The Emotions of London
(2016)
A few years ago, a group formed by Ben Allen, Cameron Blevins, Ryan Heuser, and Matt Jockers decided to use topic modeling to extract geographical information from nineteenth-century novels. Though the study was eventually abandoned, it had revealed that London-related topics had become significantly more frequent in the course of the century, and when some of us were later asked to design a crowd-sourcing experiment, we decided to add a further dimension to those early findings, and see whether London place-names could become the cornerstone for an emotional geography of the city.
Literature, measured
(2016)
There comes a moment, in digital humanities talks, when someone raises the hand and says: "Ok. Interesting. But is it really new?" Good question... And let's leave aside the obvious lines of defense, such as "but the field is still only at its beginning!", or "and traditional literary criticism, is that always new?" All true, and all irrelevant; because the digital humanities have presented themselves as a radical break with the past, and must therefore produce evidence of such a break. And the evidence, let's be frank, is not strong. What is there, moreover, comes in a variety of forms, beginning with the slightly paradoxical fact that, in a new approach, not everything has to be new. When "Network Theory, Plot Analysis” pointed out, in passing, that a network of Hamlet had Hamlet at its center, the New York Times gleefully mentioned the passage as an unmistakable sign of stupidity. Maybe; but the point, of course, was not to present Hamlet’s centrality as a surprise; it was exactly the opposite: had the new approach not found Hamlet at the center of the play, its plausibility would have disintegrated. Before using network theory for dramatic analysis, I had to test it, and prove that it corroborated the main results of previous research.
The Multilingual Assessment Instrument for Narratives (MAIN) was designed in order to assess narrative skills in children who acquire one or more languages from birth or from early age. MAIN is suitable for children from 3 to 10 years and evaluates both comprehension and production of narratives. Its design allows for the assessment of several languages in the same child, as well as for different elicitation modes: Model Story, Retelling, and Telling. MAIN contains four parallel stories, each with a carefully designed six-picture sequence. The stories are controlled for cognitive and linguistic complexity, parallelism in macrostructure and microstructure, as well as for cultural appropriateness and robustness. The instrument has been developed on the basis of extensive piloting with more than 550 monolingual and bilingual children aged 3 to 10, for 15 different languages and language combinations. Even though MAIN has not been norm-referenced yet, its standardized procedures can be used for evaluation, intervention and research purposes. MAIN is currently available in the following languages: English, Afrikaans, Albanian, Basque, Bulgarian, Croatian, Cypriot Greek, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hebrew, Icelandic, Italian, Lithuanian, Norwegian, Polish, Russian, Spanish, Standard Arabic, Swedish, Turkish, Vietnamese, and Welsh.
The Shared Task on Source and Target Extraction from Political Speeches (STEPS) first ran in 2014 and is organized by the Interest Group on German Sentiment Analysis (IGGSA). This volume presents the proceedings of the workshop of the second iteration of the shared task. The workshop was held at KONVENS 2016 at Ruhr-University Bochum on September 22, 2016.
As in the first edition of the shared task the main focus of STEPS was on fine-grained sentiment analysis and offered a full task as well as two subtasks for the extraction Subjective Expressions and/or their respective Sources and Targets.
In order to make the task more accessible, the annotation schema was revised for this year’s edition and an adjudicated gold standard was used for the evaluation. In contrast to the pilot task, this iteration provided training data for the participants, opening the Shared Task for systems based on machine learning approaches.
The gold standard1 as well as the evaluation tool2 have been made publicly available to the research community via the STEPS’ website.
We would like to thank the GSCL for their financial support in annotating the 2014 test data, which were available as training data in this iteration. A special thanks also goes to Stephanie Köser for her support on preparing and carrying out the annotation of this year’s test data. Finally, we would like to thank all the participants for their contributions and discussions at the workshop.
NLP4CMC III : 3rd workshop on natural language processing for computer-mediated communication
(2016)
The present paper reports the first results of the compilation and annotation of a blog corpus for German. The main aim of the project is the representation of the blog discourse structure and relations between its elements (blog posts, comments) and participants (bloggers, commentators). The data included in the corpus were manually collected from the scientific blog portal SciLogs. The feature catalogue for the corpus annotation includes three types of information which is directly or indirectly provided in the blog or can be construed by means of statistical analysis or computational tools. At this point, only directly available information (e.g., title of the blog post, name of the blogger etc.) has been annotated. We believe, our blog corpus can be of interest for the general study of blog structure or related research questions as well as for the development of NLP methods and techniques (e.g. for authorship detection).

Der vorliegende Text ist das Ergebnis einer sondierenden Vorstudie zur Vorbereitung einer qualitativen empirischen Befragung zum Umgang mit Wasser in chinesischen Haushalten, die im November 2015 im Rahmen des Projekts SEMIZENTRAL in Qingdao, China, durchgeführt wurde (Publikation in Vorbereitung). Das vom BMBF geförderte Projekt SEMIZENTRAL wird vom Institut IWAR der Technischen Universität Darmstadt geleitet (siehe http://www.semizentral.de/home/). Das ISOE ist Partner im Forschungsverbund und führt eine Stoffstrom- und eine damit verbundene Vulnerabilitätsanalyse für das Gebiet der Implementierung durch. In diesem Zusammenhang ist es wichtig, Einflussfaktoren des Umgangs mit Wasser durch die Bevölkerung kennenzulernen.
Gestützt auf das integrative Konzept der Wasserkultur werden im nachfolgenden Text die Ergebnisse einer diesbezüglichen Recherche vorgestellt. Dabei werden natürliche, infrastrukturelle, soziale, kulturelle, ökonomische und verhaltensbezogene Aspekte der Wasserverfügbarkeit, der Ansprüche an Wasserqualität und des Umgangs mit Wasser in China thematisiert.
Euro area shadow banking activities in a low-interest-rate environment: a flow-of-funds perspective
(2016)
Very low policy rates as well as the substantial redesign of rules and supervisory institutions have changed background conditions for the Euro Area’s financial intermediary sector substantially. Both policy initiatives have been targeted at improving societal welfare. And their potential side effects (or costs) have been discussed intensively, in academic as well as policy circles. Very low policy rates (and correspondingly low market rates) are likely to whet investors’ risk taking incentives. Concurrently, the tightened regulatory framework, in particular for banks, increases the comparative attractiveness of the less regulated, so-called shadow banking sector. Employing flow-of-funds data for the Euro Area’s non-bank banking sector we take stock of recent developments in this part of the financial sector. In addition, we examine to which extent low interest rates have had an impact on investment behavior. Our results reveal a declining role of banks (and, simultaneously, an increase in non-bank banking). Overall intermediation activity, hence, has remained roughly at the same level. Moreover, our findings also suggest that non-bank banks have tended to take positions in riskier assets (particularly in equities). In line with this observation, balance-sheet based risk measures indicate a rise in sector-specific risks in the non-bank banking sector (when narrowly defined).
Der Beitrag untersucht das in jüngerer Zeit verstärkt diskutierte Phänomen einer – tatsächlichen oder vermeintlichen – „anglo-amerikanischen Rechts-hegemonie“. Es geht dabei um die Frage, ob die Rechtsordnungen Deutschlands und der Europäischen Union unter eine Vormachtstellung des amerikanischen Rechtsdenkens und amerikanischer Regelungsmuster geraten sind oder eine solche vielleicht sogar selbst aktiv befördert haben. In dem Beitrag wird diese Diskussion aus zivilrechtlicher Perspektive aufgegriffen. Nach einer Konkretisierung des Topos der Rechtshegemonie werden dabei zunächst einige Grundcharakteristika des amerikanischen Rechtssystems und des deutschen Rechtssystems gegenübergestellt und zusammengefasst, in welchen Bereichen das deutsche und das europäische Recht in den vergangenen Jahrzehnten durch amerikanische Denk- und Regelungsmuster überformt worden sind. Im Anschluss erfolgt eine Bewertung der zuvor skizzierten Entwicklung, wobei die Unterscheidung zwischen einem intrinsisch orientierten und einem funktional orientierten Verständnis von Rechtskultur als ein Kernproblem der jüngeren rechtsvergleichenden Diskussion im Zentrum steht. Im Ergebnis wird eine tendenziell skeptische Perspektive gegenüber dem suggestiven Bild eines Wettbewerbs der Rechtsordnungen eingenommen und die in jüngerer Zeit häufig geäußerte These der globalfunktionalen Überlegenheit eines wettbewerbsorientierten Rechtsmodells in Zweifel gezogen.

We use detailed data on exporters from Costa Rica, Ecuador and Uruguay as well as on their buyers to show that: aggregate exports are disproportionally driven by few multi-buyers exporters; and each multi-buyer exporter's foreign sales of any product are in turn accounted for by few dominant buyers. We propose an analytically solvable multi-country model of endogenous selection in which dominant exporters, dominant products and dominant buyers emerge in parallel as multi-product sellers with heterogeneous technologies compete for buyers with heterogeneous needs. The model not only provides an explanation of the existence of dominant buyers but also makes specific predictions on how the relative importance of dominant buyers should vary across export destinations depending on their market size and accessibility. We show that these predictions are borne out by our data and discuss their welfare implications in terms of gains from trade.
100 Jahre Fachbereich Rechtswissenschaft ist auch ein Grund, derer zu gedenken, die über eine lange Strecke dieser Zeitspanne das Bild des Fachbereichs entscheidend mitgeprägt haben, aber nicht mehr mitfeiern können. Darunter verdient ein Strafrechtsprofessor und Rechtsphilosoph besondere Hervorhebung und Würdigung. Prof. Dr. Dr. h.c. mult. Winfried Hassemer. Das Verständnis von der gegenseitigen Befruchtung in Theorie-Praxis-Projekten brachte Hassemer aus der akademischen Welt mit in seine hohen Staatsämter: Hessischer Datenschutzbeauftragter, Richter und Vizepräsident des Bundesverfassungsgerichts. Schließlich konnte er in der Rolle des Anwalts gleichsam als „Gegenprobe“ auch noch seine schon lange gezeigte Zuneigung zum Beruf des Strafverteidigers erleben. Der fruchtbare Dialog zwischen Theorie und Praxis setzte sich 12 Jahre lang im „Frankfurter Arbeits-Kreis Strafrecht“ („FAKS“) fort, zu dessen Gründern Hassemer gehörte. Dabei haben Strafverteidiger, Richter, Staatsanwälte, Ministerialbürokratie, Strafvollzugs und Polizeibeamte mit auch Rechtswissenschaftlern im konstruktiven Diskurs die Abstände zwischen unseren „Berufswelten“ verringert. Im Zentrum stand sein Bekenntnis, dass das staatliche Strafen ein „blutiges Geschäft“ ist, das nur als ultima ratio und auch nur dann zu rechtfertigen ist, wenn „schützende Formen“ des Verfahrensrechts strafbegrenzend wirken. Der Fachbereich Rechtswissenschaft wird auch in dem jetzt beginnenden zweiten Jahrhundert seines Bestehens das Andenken an Winfried Hassemer hoch halten.
This paper studies the role of the Community Reinvestment Act (CRA) in the recent US housing boom-bust cycle. Using a difference-in-differences matching estimation, I find that the enhancement of CRA enforcement in 1998 caused a 7.7 percentage points increase in annual growth rate of mortgage lending by CRA-regulated banks to CRA-eligible census tracts relative to a group of similar-income CRA-ineligible census tracts within the same state. Financial institutions which are not subject to the CRA, however, do not show any change in their mortgage supply between these two types of census tracts after 1998. I take advantage of this exogenous shift in mortgage supply within an instrumental variable framework to identify the causal effect of mortgage supply on housing prices. I find that every 1 percentage point higher annual growth rate of mortgage supply leads to 0.3 percentage points higher annual growth rate of housing prices. Reduced form regressions show that CRA-eligible neighborhoods experienced higher house price growth during the boom and sharper decline during the bust period. I use placebo tests to confirm that this effect is in fact channeled through the shift in mortgage supply by CRA-regulated banks and not by unobserved demand factors. Furthermore, my results indicate that CRA-induced mortgages went to borrowers with lower FICO scores, carried higher interest rates, and encountered more frequent delinquencies.
Within the framework of the Transboundary Waters Assessment Programme (TWAP), initiated by the Global Environment Facility (GEF), we contributed to a comprehensive baseline assessment of transboundary aquifers (TBAs) by quantifying different groundwater indicators using the global water resources and water use model WaterGAP 2.2. All indicators were computed under current (2010) and projected conditions in 2030 and 2050 for 91 selected TBAs larger than 20,000 km2 and for each nation’s share of the TBAs (TBA-CU: country unit). TBA outlines were provided by the International Groundwater Resources Assessment Centre (IGRAC). The set of indicators comprises groundwater recharge, groundwater depletion, per-capita groundwater recharge, dependency on groundwater, population density, and groundwater development stress (groundwater withdrawals to groundwater recharge). Only the latter four indicators were projected to 2030 and 2050. Current-state indicators were quantified using the Watch Forcing Data climate dataset, while projections were based on five climate scenarios that were computed by five global climate models for the high-emissions scenario RCP 8.5. Water use projections were based on the Shared Socio-economic Pathway SSP2 developed within ISI-MIP. Furthermore, two scenarios of future irrigated areas were explored. For individual water use sectors, the fraction of groundwater abstraction was assumed to remain at the current level.
According to our assessment, aquifers with the highest current groundwater depletion rates worldwide are not transboundary. Exceptions are the Neogene Aquifer System (Syria) with 53 mm/yr between 2000 and 2009 and the Indus River Plain aquifer (India) with 28 mm/yr. For current conditions, we identified 20 out of 258 TBA-CUs suffering from medium to very high groundwater development stress, which are located in the Middle East and North Africa region, in South Asia, China, and the USA. Considering projections, ensemble means of per-cent changes or percent point changes to current conditions were determined. Per-capita groundwater recharge is projected to decrease in 80-90% of all TBA-CUs until 2030/2050. Due to the strongly varying projections of the global climate models, we applied a worst-case scenario approach to define future hotspots of groundwater development stress, taking into account the strongest computed increase until either 2030 or 2050 among all scenarios and individual GCMs. Based on this approach, the number of TBA-CUs under at least medium groundwater development stress increases from 20 to 58, comprising all hotspots under current conditions. New hotspots are projected to develop mainly in Sub-Saharan Africa, China, and Mexico.
I show that disruptions to personal sources of financing, aside from commercial lending supply shocks, impair the survival and growth of small businesses. Entrepreneurs holding deposit accounts at retail banking institutions that defaulted following the financial crisis reduce personal borrowing and are consequently more likely to exit their firm. Exposure to the corresponding investment losses from delisted publicly traded bank stocks strongly reduces the rate of firm survival, particularly for early-stage ventures. At the intensive margin, owners who remain in business reduce employees after personal wealth losses. My results suggest that personal finance is an important component of firm financing.
We investigate the role of competition on the outcome of Austrian Treasury auctions. Austria's EU accession led to an increase in the number of banks participating in treasury auctions. We use structural estimates of bidders' private values to examine the effect of increased competition on auction performance: We find that increased competition reduced bidder surplus substantially, but less than reduced form estimates would suggest. A significant component of the surplus reduction is due to more aggressive bidding. Counterfactuals establish that as competition increases, concerns regarding auction format play a smaller role.
Bei Erlass des PUAG verzichtete der einfache Gesetzgeber bewusst auf eine mögliche Vereidigung von Zeugen vor Untersuchungsausschüssen. Das Recht zur Zeugenvereidigung ist aber, wie dargelegt wird, in der Verfassung selbst gewährleistet. Damit sind intrikate Fragen sowohl zum Verhältnis von Verfassung und Gesetz sowie im bundesstaatlichen Verhältnis aufgeworfen. Dem einfachen Gesetzgeber steht zwar die Befugnis zu, ein Gesetz über Untersuchungsausschüsse zu erlassen, fraglich ist aber, ob er berechtigt ist, Untersuchungsausschüssen des Bundestages Rechte zu nehmen, die ihnen nach dem Grundgesetz zustehen; dies ist im Ergebnis zu verneinen. Die bundesrechtlichen Änderungen zeitigten indes sogar Folgen für das Verfassungsrecht der Länder. Infolge der mit Einführung des PUAG gleichzeitig erfolgten Änderung des StGB entschied der Hessische Staatsgerichtshof im Jahr 2011, dass Untersuchungsausschüssen des Landtages ein Vereidigungsrecht nicht mehr zustehe, welches er zuvor aus der Hessischen Verfassung abgeleitet hatte. Der Gerichtshof gesteht dadurch dem Strafrecht die Macht zu, öffentlich-rechtliche Kompetenzen in den Ländern zu ändern.
From 1963 through 2015, idiosyncratic risk (IR) is high when market risk (MR) is high. We show that the positive relation between IR and MR is highly stable through time and is robust across exchanges, firm size, liquidity, and market-to-book groupings. Though stock liquidity affects the strength of the relation, the relation is strong for the most liquid stocks. The relation has roots in fundamentals as higher market risk predicts greater idiosyncratic earnings volatility and as firm characteristics related to the ability of firms to adjust to higher uncertainty help explain the strength of the relation. Consistent with the view that growth options provide a hedge against macroeconomic uncertainty, we find evidence that the relation is weaker for firms with more growth options.
We consider an infinitely repeated game in which a privately informed, long-lived manager raises funds from short-lived investors in order to finance a project. The manager can signal project quality to investors by making a (possibly costly) forward-looking disclosure about her project’s potential for success. We find that if the manager’s disclosures are costly, she will never release forward-looking statements that do not convey information to external investors. Furthermore, managers of firms that are transparent and face significant disclosure-related costs will refrain from forward-looking disclosures. In contrast, managers of opaque and profitable firms will follow a policy of accurate disclosures. To test our findings empirically, we devise an index that captures the quantity of forward-looking disclosures in public firms’ 10-K reports, and relate it to multiple firm characteristics. For opaque firms, our index is positively correlated with a firm’s profitability and financing needs. For transparent firms, there is only a weak relation between our index and firm fundamentals. Furthermore, the overall level of forward-looking disclosures declined significantly between 2001 and 2009, possibly as a result of the 2002 Sarbanes-Oxley Act.
An important prerequisite for the efficiency of bail-in as a regulatory tool is that debt holders are able to bear the cost of a bail-in. Examining European banks’ subordinated debt we caution that households may be investors in bail-in able bonds. Since households do not fulfil the aforementioned prerequisite, we argue that European bank supervisors need to ensure that banks’ bail-in bonds are held by sophisticated investors. Existing EU market regulation insufficiently addresses mis-selling of bail-in instruments.
owards their best performing products; and also extend the range of products sold to that market. We develop a theoretical model of multiproduct firms and derive the specific demand and cost conditions needed to generate these product-mix reallocations. Our theoretical model highlights how the increased competition from demand shocks in export markets - and the induced product mix reallocations - induce productivity changes within the firm. We then empirically test for this connection between the demand shocks and the productivity of multi-product firms exporting to those destinations. We find that the effect of those demand shocks on productivity are substantial - and explain an important share of aggregate productivity fluctuations for French manufacturing.
This paper explores the impact of immigrants on the imports, exports and productivity of service- producing firms in the U.K. Immigrants may substitute for imported intermediate inputs (offshore production) and they may impact the productivity of the firm as well as its export behavior. The first effect can be understood as the re-assignment of offshore productive tasks to immigrant workers. The second can be seen as a productivity or cost cutting effect due to immigration, and the third as the effect of immigrants on specific bilateral trade costs. We test the predictions of our model using differences in immigrant inflows across U.K. labor markets, instrumented with an enclave-based instrument that distinguishes between aggregate and bilateral immigration, as well as immigrant diversity. We find that immigrants increase overall productivity in service-producing firms, revealing a cost cutting impact on these firms. Immigrants also reduce the extent of country-specific offshoring, consistent with a reallocation of tasks and, finally, they increase country-specific exports, implying an important role in reducing communication and trade costs for services.
Intrinsic motivation for honesty is perceived as an important determinant of large and persistent variation in cheating behavior. However, little is known about its actual role due to challenges in obtaining precise measures of motivation for honesty, as well as field outcomes on cheating. We fill these gaps using a unique setting of informal milk markets in India. A novel behavioral experiment, which combines a standard die roll task with Bluetooth technology, is used to measure motivation for honesty of milkmen at both extensive and intensive margins. We then buy milk from the same milkmen and show that cheating in the field, measured by the amount of water added to milk, widens significantly with a milkman’s degree of dishonesty. Additional analyses show that conventional binary measure of motivation for honesty suffers from measurement errors, resulting in underestimation of this association.
Understanding the shift from micro to macro-prudential thinking: a discursive network analysis
(2016)
While some economists argued for macro-prudential regulation pre-crisis, the macro-prudential approach and its emphasis on endogenously created systemic risk have only gained prominence post-crisis. Employing discourse and network analysis on samples of the most cited scholarly works on banking regulation as well as on systemic risk (60 sources each) from 1985 to 2014, we analyze the shift from micro to macro-prudential thinking in the shift to the post crisis period. Our analysis demonstrates that the predominance of formalism, particularly, partial equilibrium analysis along with the exclusion of historical and practitioners’ styles of reasoning from banking regulatory studies impeded economists from engaging seriously with the endogenous sources of systemic risk prior to the crisis. Post-crisis, these topics became important in this discourse, but the epistemological failures of banking regulatory studies pre-crisis were not sufficiently recognized. Recent attempts to conceptualize and price systemic risk as a negative externality point to the persistence of formalism and equilibrium thinking, with its attending dangers of incremental innovation due to epistemological barriers constrains theoretical progress, by excluding observed phenomena, which cannot yet be accommodated in mathematical models.
This paper investigates whether the overpricing of out-of-the money single stock calls can be explained by Tversky and Kahneman’s (1992) cumulative prospect theory (CPT). We argue that these options are overpriced because investors overweight small probability events and overpay for such positively skewed securities, i.e., characteristics of lottery tickets. We match a set of subjective density functions derived from risk-neutral densities, including CPT with the empirical probability distribution of U.S. equity returns. We find that overweighting of small probabilities embedded in CPT explains on average the richness of out-of-the money single stock calls better than other utility functions. The degree that agents overweight small probability events is, however, strongly timevarying and has a horizon effect, which implies that it is less pronounced in options of longer maturity. We also find that time-variation in overweighting of small probabilities is strongly explained by market sentiment, as in Baker and Wurgler (2006).
We use the Italian Survey of Household Income and Wealth, a rather unique dataset with a long time dimension of panel information on consumption, income and wealth, to structurally estimate a buffer-stock saving model. We exploit the information contained in the joint dynamics of income, consumption and wealth to quantify the degree of insurance against income risk. The estimated model implies that Italian households can insure between 89 and 95 percent of a transitory and between 7 and 9 percent of a permanent income shock. Compared to existing empirical estimates for the same dataset, our findings suggest that Italian households do not have access to significant insurance beyond self-insurance.
We provide an assessment of the Basel Committee on Banking Supervision (BCBS) proposal to restrict the internal ratings-based approach on bank risk and to introduce risk-weighted asset floors. If well enforced, risk-sensitive capital regulation results in a more efficient credit allocation compared to the standard approach. Thus, the internal ratings-based approach should be maintained. Further, the use of internal ratings-based output floors potentially results in unintended negative side effects. Input floors are likely a valuable tool to achieve risk-weighted assets comparability. Finally, the proposed measures have a potential detrimental impact for European banks as compared to others.
Die Goethe-Universität befindet sich seit einigen Jahren in einem deutlichen Wandel. Der Campus Westend wird zum Zentralcampus ausgebaut und auch personell wächst die Goethe-Universität. Fast 47.000 Studierende und mehr als 5.000 Beschäftigte (Stand Herbst 2014) studieren und arbeiten an den Campussen.
Die Goethe-Universität ist damit einer der bedeutendsten Verkehrserzeuger in Frankfurt, da nahezu täglich über 50.000 Personen ihren Studien- oder Arbeitsplatz an der Goethe-Universität erreichen müssen und auch zwischen den verschiedenen Standorten pendeln.
Das folgende Arbeitspapier befasst sich mit der Mobilität der Studierenden und der Beschäftigten der Goethe-Universität, die mittels zweier Online-Befragungen erhoben und analysiert wurden. Es werden die zentralen Erkenntnisse bezüglich der vorhandenen Mobilitätsressourcen und wohnungsnahen Mobilitätsangebote, des Verkehrsverhaltens hinsichtlich der Häufigkeit, Dauer und Länge von Wegen zu und zwischen den Campussen und der Nutzung von Verkehrsmitteln, den Einstellungen zu den verschiedenen Verkehrsmitteln und die Nutzungsbereitschaft bezüglich optionaler Mobilitätsangebote der Universität vorgestellt.
Abschließend wird ein Resümee über den durch die Universität erzeugten Verkehr gezogen und auf Basis umfassender zielgruppenspezifischer Erkenntnisse werden Vorschläge zur Entzerrung, Verlagerung und Optimierung für ein universitäres Mobilitätsmanagement entwickelt.
Chen and Zadrozny (1998) developed the linear extended Yule-Walker (XYW) method for determining the parameters of a vector autoregressive (VAR) model with available covariances of mixed-frequency observations on the variables of the model. If the parameters are determined uniquely for available population covariances, then, the VAR model is identified. The present paper extends the original XYW method to an extended XYW method for determining all ARMA parameters of a vector autoregressive moving-average (VARMA) model with available covariances of single- or mixed-frequency observations on the variables of the model. The paper proves that under conditions of stationarity, regularity, miniphaseness, controllability, observability, and diagonalizability on the parameters of the model, the parameters are determined uniquely with available population covariances of single- or mixed-frequency observations on the variables of the model, so that the VARMA model is identified with the single- or mixed-frequency covariances.
Who gains from inter-corporate credit? To answer this question we measure the impact of the announcements of inter-corporate loans in China on the stock prices of the firms involved. We find that the average abnormal return for the issuers of inter-corporate loans is significantly negative, whereas it is positive for the receivers. Issuing firms may be perceived by investors to have run out of worthwhile projects to finance, while receiving firms are being certified as creditworthy. Subsequent firm performance and investment confirms these valuations as overall accurate.
Rechtsvergleichend wird betrachtet, wem in Deutschland und den USA das Recht zu wählen zusteht. Es wird dargestellt, dass die gleichheitsrechtlich begründete Ausdehnung des Wahlrechts auf früher exkludierte Personengruppen keine lineare Fortschrittsgeschichte ist.
Der Kampf um das Wahlrecht in den USA war weitgehend Teil des Kampfes gegen Rassendiskriminierung. Änderungen des Wahlrechts in bestimmten Einzelstaaten der USA stellen einen erheblichen Rückschritt im Hinblick auf die Allgemeinheit der Wahl dar, da sie Verschärfungen mit sich bringen, die ohnehin schon benachteiligte Bevölkerungsgruppen faktisch vom Wahlrecht ausschließen.
Auch in Deutschland war es ein langwieriger Prozess, bis sich die Allgemeinheit der Wahl durchsetzte. Aber auch in Deutschland ist die Allgemeinheit der Wahl noch in mehrfacher Hin-sicht beschränkt. Insbesondere die Einschränkungen des Wahlrechts für Strafgefangene wie auch das Wahlrecht für Auslandsdeutsche sind verfassungsrechtliche sehr problematisch. Auch Reformvorschläge, wie etwa die Einführung eines Kinderwahlrechts, treuhänderisch durch die Eltern ausgeübt, sind verfassungsrechtlich äußerst bedenklich.
In a production economy with trade in financial markets motivated by the desire to share labor-income risk and to speculate, we show that speculation increases volatility of asset returns and investment growth, increases the equity risk premium, and reduces welfare. Regulatory measures, such as constraints on stock positions, borrowing constraints, and the Tobin tax have similar effects on financial and macroeconomic variables. Borrowing limits and a financial transaction tax improve welfare because they substantially reduce speculative trading without impairing excessively risk-sharing trades.
This study looks at the interrelationship between fiscal policy and safe assets as there is surprisingly little analysis about this beyond fleeting references. The study argues that from a certain point more public debt will not “buy” more safety: countries face a kind of “safe-assets Laffer curve” with a maximum amount of safe assets at some level of indebtedness. The position and “stability” of this curve depend on a number of national and international factors, including the international risk appetite and, as a more recent factor, QE policies by central banks. The study also finds evidence of declining safe assets as reflected in government debt ratings.
In the wake of the recent financial crisis, significant regulatory actions have been taken aimed at limiting risks emanating from trading in bank business models. Prominent reform proposals are the Volcker Rule in the U.S., the Vickers Report in the UK, and, based on the Liikanen proposal, the Barnier proposal in the EU. A major element of these reforms is to separate “classical” commercial banking activities from securities trading activities, notably from proprietary trading. While the reforms are at different stages of implementation, there is a strong ongoing discussion on what possible economic consequences are to be expected. The goal of this paper is to look at the alternative approaches of these reform proposals and to assess their likely consequences for bank business models, risk-taking and financial stability. Our conclusions can be summarized as follows: First, the focus on a prohibition of only proprietary trading, as envisaged in the current EU proposal, is inadequate. It does not necessarily reduce risk-taking and it likely crowds out desired trading activities, thereby negatively affecting financial stability. Second, there is potentially a better solution to limit excessive trading risk at banks in terms of potential welfare consequences: Trading separation into legally distinct or ring-fenced entities within the existing banking organizations. This kind of separation limits cross-subsidies between banking and proprietary trading and diminishes contagion risk, while still allowing for synergies across banking, non-proprietary trading and proprietary trading.
Essayistisch setzt sich diese Kolumne mit der Bevölkerungspolitik auseinander. Die Geburtenrate und die Angst vor dem Bevölkerungsschwund sind zu einem wesentlichen Thema im medialen und politischen Tagesgeschehen geworden. Die Sorge um den ausbleibenden Nachwuchs führt zu Forderungen, dass der Staat zur Erhöhung der Geburtenrate tätig werden müsse im Sinne einer obligatorischen Staatsaufgabe, z.B. um die Sozialsysteme zu sichern. Doch die Steigerung der Geburtenrate ist kein legitimes staatliches Ziel. Die grundrechtliche Freiheit der Eltern verlangt, dass der Staat sich eines Einflusses enthält und keine Anreize zum Kinderbekommen setzt. Familienförderung hat lediglich dafür zu sorgen, dass die Bedingungen für die bereits bestehenden Familien adäquat sind und muss sich als „Ausgleich“ für (finanzielle) Lasten deuten lassen. Einige Förderungsmittel sind kritisch zu be-trachten, da sie überproportional relativ wohlhabenden Familien zugutekommen sowie Anreize setzen, viele Kinder zu bekommen - durch die Anrechnung auf Sozialleistungen jedoch nicht bei armen Familien. Die Veränderung in der Bevölkerungsentwicklung wird Folgen haben, die sich nicht durch eine rückwärtsgewandte, allein an der Steigerung der Geburtenrate orientierte Politik verhindern lassen. Stattdessen ist es an der Zeit, die notwendigen Anpassungsprozesse anzugehen und zu gestalten.
Der Aufsatz untersucht das Verhältnis von Antidiskriminierungsrecht und Diversität in der Rechtswissenschaft. Das Verhältnis der beiden Begriffe zueinander ist nicht spannungsfrei. Der Aufsatz befasst sich näher mit der Frage, wie Gleichheit zu verstehen ist und stellt zwei Modelle zum Verständnis von Gleichheit vor: Differenzierungsverbot und Dominierungsverbot. Im Vergleich erweist sich ein Verständnis als Dominierungsverbot wesentlich leistungsfähiger als eine Deutung als Differenzierungsverbot, jedenfalls wenn es um komplexere Formen von Benachteiligung geht.
Im Anschluss wird erörtert, welche Faktoren die Leistungsfähigkeit des Antidiskriminierungsrechts im Hochschulbereich, in dem Frauen auf höheren Positionen immer noch unterrepräsentiert sind, beeinflussen. Hierbei werden verschiedene Erklärungsansätze dargestellt und strukturelle Hürden des Antidiskriminierungsrechts aufgezeigt. Denn die Frage der Durchsetzbarkeit rechtlicher Normen ist ein zentrales Thema für die praktische Wirksamkeit von Antidiskriminierungsrecht. Insoweit ist freilich auch ein Rückgriff auf die Herstellung von Diversität wenig erfolgversprechend.
In this paper, we examine how the institutional design affects the outcome of bank bailout decisions. In the German savings bank sector, distress events can be resolved by local politicians or a state-level association. We show that decisions by local politicians with close links to the bank are distorted by personal considerations: While distress events per se are not related to the electoral cycle, the probability of local politicians injecting taxpayers’ money into a bank in distress is 30 percent lower in the year directly preceding an election. Using the electoral cycle as an instrument, we show that banks that are bailed out by local politicians experience less restructuring and perform considerably worse than banks that are supported by the savings bank association. Our findings illustrate that larger distance between banks and decision makers reduces distortions in the decision making process, which has implications for the design of bank regulation and supervision.
In order to better differentiate the drivers of corporations’ actions, in particular shareholder wealth and stakeholder interests, the paper explores the significance of the comply or explain-principle and its underlying enforcement mechanisms more generally. Against this background, compliance rates with specific provisions may shed a light on companies’ reasons for following the code. An analysis of these rates at the example of distinct provisions of the German Corporate Governance Code is therefore entered into. In light of the current corporate governance debate and the legitimacy problems that are raised, among the code provisions that exemplify these questions very well are those regulating incentive pay, severance pay caps, and age limits for supervisory board members. Their analysis will lay a basis for an answer to the question about what motivates companies to comply with the code. The motivation then paves the way to arrive at a further specification of the determinants of the regulatory evolution of the Code and the range of stakeholders and their concerns that enter into it.
Scholarship and practice
(2016)
How can I as an international lawyer, conscious that international law is deeply implicated in today’s global injustices and that the course of history will not be changed by any grand legal design, practice law responsibly? Taking as a point of departure my own desire not to seek comfort in the formulation of a critique of law, but to aspire to a responsible practice, I consult two quite different bodies of work: first, critical theory of law and second, recent scholarship on international law that argues a practice guided by ethics may enhance the legitimacy of international law. I turn then to my own practice of international economic law focusing on my occasional role as legal expert on the so-called megaregionals the EU aims to conclude with Canada and the United States. I propose that the debate on international economic law lacks an investigation into the role of law in shaping political economy; that this lack can be explained by the compartmentalization of expertise which leads to justification gaps with respect to projects such as the megaregionals. One way how lawyers can assume responsibility is to work on closing these gaps even if it means leaving the ‘inside’ of the legal discipline. Finally, I suggest that a responsible legal practice of social change might follow Roberto Unger’s call for institutional imagination. Maybe I can satisfy my wish for a transformative practice by joining forces with friends in experimenting with institutions, hoping to build an alternative political economy.
Mediation in der Türkei : Betrachtung ausgewählter Aspekte im Vergleich zur Mediation in Deutschland
(2016)
Angesichts der vergleichsweise noch sehr jungen Entwicklung der Mediation in der Türkei mag man es auf den ersten Blickerstaunlich finden, dass in der Türkei zeitgleich mit Deutschland ein Mediationsgesetz geschaffen wurde. Die Mediation als außergerichtliches Vermittlungsverfahren gründet darauf, dass Streitparteien freiwillig und selbstbestimmt ihren Konflikt mit Unterstützung eines Mediators einer gemeinsam entwickelten Lösung zuführen. Dies sind die Grundprinzipien der Mediation, die sowohl dem deutschen als auch dem türkischen Mediationsgesetz als Basis dienen.
Trotz vieler Ähnlichkeiten haben die kulturellen Besonderheiten beider Länder Einfluss auf die rechtliche Ausgestaltung dieses Einigungsverfahrens sowie dessen Umsetzung in der Praxis .Ziel des vorliegenden Arbeitspapiers ist es, dem Leser einen Einblick in die Unterschiede und Gemeinsamkeiten der Mediation in der Türkei und Deutschland zu vermitteln und dabei vergleichend zu untersuchen , ob und inwieweit landestypischen Spezifika in der Entstehungsgeschichte, den Grundlagen und der Praxis der Mediation erkennbar und durch gesellschaftliche und kulturelle Faktoren erklärbar sind.
This paper describes cash equity markets in Germany and their evolution against the background of technological and regulatory transformation. The development of these secondary markets in the largest economy in Europe is first briefly outlined from a historical perspective. This serves as the basis for the description of the most important trading system for German equities, the Xetra trading system of Deutsche Börse AG. Then, the most important regulatory change for European and German equity markets in the last ten years is illustrated: the introduction of the Markets in Financial Instruments Directive (MiFID) in 2007. Its implications on equity trading in Germany are analyzed against the background of the current status of competition in Europe. Recent developments in European equity markets like the emergence of dark pools and algorithmic / high frequency trading are portrayed, before an outlook on new regulations (MiFID II, MiFIR) that will likely come into force in early 2018 will close the paper.
The article, which summarizes key findings of my German book ‘Die Gemeinfreiheit. Begriff, Funktion, Dogmatik’ (‘The Public Domain: Theory, Func-tion, Doctrine’), asks whether there are any provisions or principles under Ger-man and EU law that protect the public domain from interference by the legisla-ture, courts and private parties. In order to answer this question, it is necessary to step out of the intellectual property (IP) system and to analyze this body of law from the outside, and – even more important – to develop a positive legal conception of the public domain as such. By giving the public domain a proper doctrinal place in the legal system, the structural asymmetry between heavily theorized and protected IP rights on the one hand and a neglected public do-main on the other is countered. The overarching normative purpose is to devel-op a framework for a balanced IP system, which can only be achieved if the public domain forms an integral part of the overall regulation of information.
Rechtswissenschaftliche Abhandlungen und Veranstaltungen zu internationalen Gerichten stehen häufig unter dem Titel „Internationale Streitbeilegung“. Es wäre aber viel besser, so die Leitthese dieses Beitrags, solche Texte und Veranstaltungen als „internationale Gerichtsbarkeit“ zu betiteln. Dies ist keineswegs ein bloßer Streit um Worte, da hinter diesen Alternativen unterschiedliche rechtswissenschaftliche Auffassungen stehen. Im Folgenden sei gezeigt, dass anders als die Be-zeichnung „Internationale Streitbeilegung“ suggeriert, nicht nur eine, sondern vier Funktionen die Rechtsprechung heutiger internationaler Gerichte kennzeichnen. Es handelt sich dabei um: Streitbeilegung im Einzelfall, Stabilisierung normativer Erwartungen, Rechtschöpfung sowie Kontrolle und Legitimation öffentlicher Gewalt. Die Ana-lyse dieser Funktionen zeigt, dass die Bezeichnung „Internationale Streitbeilegung“ überkommen ist. Entsprechend sollte die Bezeichnung des Fachs geändert und es als Teil des Fachs internationale Institutionen verortet werden.
As the financial crisis gathered momentum in 2007, the United States Federal Reserve brought its policy interest rate aggressively down from 5¼ percent in September 2007 to virtually zero by December 2008. In contrast, although facing the same economic and financial stress, the European Central Bank’s first action was to raise its policy rate in July 2008. The ECB began lowering rates only in October 2008 once near global financial meltdown left it with no choice. Thereafter, the ECB lowered rates slowly, interrupted by more hikes in April and July 2011. We use the “abnormal” increase in stock prices — the rise in the stock price index that was not predicted by the trend in the previous 20 days — to measure the market’s reaction to the announcement of the interest rate cuts. Stock markets responded favorably to the Fed interest rate cuts but, on average, they reacted negatively when the ECB cut its policy rate. The Fed’s early and aggressive rate cuts established its intention to provide significant monetary stimulus. That helped renew market optimism, consistent with the earlier economic recovery. In contrast, the ECB started building its shelter only after the storm had started. Markets interpreted even the simulative ECB actions either as “too little, too late” or as signs of bad news. We conclude that by recognizing the extraordinary nature of the circumstances, the Fed’s response not only achieved better economic outcomes but also enhanced its credibility. The ECB could have acted similarly and stayed true to its mandate. The poorer economic outcomes will damage the ECB’s long-term credibility.
On 14 September 2016, the European Commission proposed a Directive on “copyright in the Digital Single Market”. This proposal includes an Article 11 on the “protection of press publications concerning digital uses”, according to which “Member States shall provide publishers of press publications with the rights provided for in Article 2 and Article 3(2) of Directive 2001/29/EC for the digital use of their press publications.” Relying on the experiences and debates surrounding the German and Spanish laws in this area, this study presents a legal analysis of the proposal for an EU related right for press publishers (RRPP). After a brief overview over the general limits of the EU competence to introduce such a new related right, the study critically examines the purpose of an RRPP. On this basis, the next section distinguishes three versions of an RRPP with regard to its subject-matter and scope, and considers the practical and legal implications of these alternatives, in particular having regard to fundamental rights.
Die Entwicklung des europäischen und deutschen Markenrechts in den letzten Jahrzehnten lässt sich auf die Kurzformel „vom Warenzeichen zum Markeneigentum“ bringen. An die Stelle einer lauterkeitsrechtlich fundierten Gewährleistung unverfälschten Wettbewerbs ist ein abstrak-tes, fungibles Eigentum an allen potentiell unterscheidungskräftigen Zeichen getreten. Im Beitrag wird dieser Paradigmenwechsel in Anlehnung an Thesen des 1944 erschienenen, wirtschaftssoziologischen Klassikers „The Great Transformation. Politische und ökonomische Ursprünge von Gesellschaften und Wirtschaftssystemen“ von Karl Polanyi gedeutet. In einem ersten Schritt wird erläutert, inwieweit Po-lanyis Ausgangsthese, wonach in einer Marktwirtschaft alle In- und Outputfaktoren kommodifiziert wer-den müssen, auf Marken und andere Kennzeichen übertragbar ist. Sodann wird Polanyis zentrale Er-kenntnis, dass die Kommodifizierung von Arbeit und Boden, aber eben auch von Zeichen als Kommu-nikationselementen kontingent, sogar fiktional und insgesamt alles andere als unproblematisch ist, für eine Kritik des gegenwärtigen Markenrechts fruchtbar gemacht. Und in der Tat ist auch in diesem Be-reich eine Entbettung des Marktes aus der Gesellschaft zu beobachten: Die Markenkommunikation wird gegenüber nicht-marktlicher Kommunikation abgeschirmt, z.B. vor Markenparodien und -kritik. Dies löst nach Polanyi Gegenbewegungen aus, die im Markenrecht bereits so stark geworden sind, dass es nicht einmal mehr ausgeschlossen erscheint, dass sie das Markenrecht auf seinen Ausgangspunkt zurück-werfen: auf das Recht gegen unlauteren Wettbewerb.
Das Kapitalmarktrecht entwickelt sich in der Berliner Republik zu einem voll integrierten Kernbestandteil des unternehmensrechtlichen Diskurses in der Rechtswissenschaft, während es in den vorausgehenden Dekaden primär eine in den normativen Grundlagen wenig durchdrungene Praktikermaterie darstellte. Das vorliegende Essay versucht eine Erklärung für diese Beobachtung zu skizzieren, die auf einem breiten Jurisdiktionen und Nationalökonomien übergreifenden Kontext beruht, der mit den Schlagworten Europäisierung und Globalisierung nur platt und unscharf umschrieben ist. Dabei geht es einerseits um eine Ausweichbewegung deutscher Unternehmen, die mit einer verstärkten Kapitalmarktorientierung eine Klemme in der Unternehmensfinanzierung zu lösen, die durch den Rückzug der vom globalen Wettbewerb erfassten Finanzindustrie aus derselben ausgelöst wurde. Auf der anderen Seite findet in der Altersvorsoge eine Abkehr von Umverteilungssystemen und eine Hinwendung zur kapitalbasierten Vorsorge statt, durch die nicht nur mehr Kapital für Investitionen statt für Konsum zur Verfügung steht, sondern auch die Interessen der Mittelschicht in vielerlei Hinsicht stärker von einer anlegerorientierten Regelung im Gesellschafts- und Kapitalmarktrecht abhängen, als von einer Arbeitnehmerorientierung im Unternehmensrecht.
This text is an only slightly modified version of the Herbert Krüger Memorial Lecture that I held upon invitation of the Arbeitskreis Überseeische Verfassungsvergleichung on 4 July 2014 at Bucerius Law School in Hamburg. My point of departure is the observation that even though the economic exploitation of natural resources triggers a multitude of distribution conflicts, international and transnational law treat these conflicts inadequately. While the New International Economic Order had as one of its objectives distributional justice between resource exporting poor states (former colonies) and resource importing high income states (mostly former imperial powers) its demands were never fully realized. Instead a transnational economic law emerged which can be interpreted as itself establishing a distribution order -- albeit a distribution order that is not oriented towards distributional justice, but rather posits the market as the best distribution device. This distribution order has depoliticized and deterritorialized distribution conflicts between resource exporting and resource importing states and has secured – through the promotion of privatizations, protection of foreign investments and dismantling of trade barriers – access to resources for the resource importing states. At the same time it has freed importing states from responsibility for the harms that accrue from resource exploitation to the resource exporting states and their populations. I call in this text for a repoliticization of distribution conflicts at the international as well as the (trans)national level, a repoliticization that may be achieved not only through the reform of political, but also economic institutions.
Die „Frankfurter Schule des Strafrechts“, eine strafrechtskritische, aber nicht abolitionistische Perspektive auf das Strafrecht, verneint die Möglichkeit eines gänzlich unpolitischen Strafrechts, und betreibt, an der Wirklichkeit des Strafrechts interessiert, grundlagenorientiert Strafrechtstheorie und -dogmatik. In dieser Tradition werden die kriminalpolitischen Herausforderungen gekennzeichnet: Das Strafrecht in der globalisierten und ökonomisierten Mediengesellschaft zunehmender Pluralität und Diversität. Die Herausforderungen, die mit diesen gesellschaftlichen Entwicklungen verbunden sind, lassen sich kennzeichnen als Balanceakt zwischen Flexibilität und Prinzipientreue. Das Strafrecht darf sich nicht fundamentalistisch auf das beschränken, was schon seit Ewigkeiten Straftat ist, muss aber auf seinem Charakter als ultima ratio beharren, und darf sich und seine Zurechnungsprinzipien, provoziert durch die neuen Gegenstände (wie z.B. die Wirtschafts- und Umweltkriminalität) und die steigenden Sicherheitsbedürfnisse einer verunsicherten und nach Prävention strebenden Gesellschaft, nicht bis zur Unkenntlichmachung verbiegen lassen.
Mobilizations in defence of ‘companion animals’ have become major sites of contestation in Chinese society in recent years. They often reject the existing ambiguity between the use of these animals as pets and as meat, demanding unambiguous respect for and protection of dogs. However, in a society where inequalities are as significant as in China, where the level of poverty, sickness, and environmental and industrial tragedies appears overwhelming, one may ask how pets’ destinies have become such a symbolic focus and source of occasional fury – for both Chinese and foreign audiences. Taking this question seriously, this article aims to examine such mobilizations in China – demanding the protection of dogs – as a starting point to theoretically unwrap the more general problem of how the perception of certain beings as ‘weak’ and as deserving the protection of society is socially constructed, and what the related choices imply. I argue that to better understand these mobilizations to protect dogs, we should not separate the focus of the calls for protection from the social web of relationships and oppositions in which they are entrenched.
Science is under pressure. In times when it is a matter of nothing less that a transformation toward sustainable development, society and politics are demanding not just reliable knowledge but above all useful knowledge. In order to be able to produce such knowledge science must change its structures and ways of working. A renewed understanding of critique can provide guidance to the process of change that must be actively shaped by science itself.* The “Great Transformation” in the direction of sustainable development is a global challenge for society (WBGU2011). All involved have stressed that this transformation, if it succeeds, will lead to profound changes in all parts of society (see PIK 2007). This applies to science as well, which after all is a part of society (WBGU2011, pp. 341 f.). For in view of an unprecedented social-ecological crisis science is coming increasingly under pressure to provide knowledge that is not only methodically reliable but also useful for dealing with the challenges ahead. It is obvious this pressure can strike at the very core of the scientific project: Any orientation toward nonscientific criteria with respect to what is to count as relevant knowledge threatens to undermine the reflexive and cooperative search for “true knowledge.”
In this situation we believe it to be crucial that science does not allow itself to become a plaything of calls for change, but rather that it itself shapes its own response to the new historical challenges. In the following, we argue that a renewed understanding of critique should be the starting point for such an endeavor.1 We will illustrate what a renewed understanding of critique might look like by posing nine theses.2 We see these theses as a contribution to the ongoing discourse on sustainability science or research for sustainable development.
Um weltweit die Wasser- und die Sanitärversorgung zu sichern, muss zeitnah in großem Umfang in neue Trinkwasser- bzw. Abwassersysteme investiert werden. Nicht nur die Länder des globalen Südens stehen im Wassersektor vor erheblichen Herausforderungen, auch die meisten Industrieländer haben Nachholbedarf und massive Investitionserfordernisse. Angesichts des globalen Investitionsbedarfes ist mit einem rasant wachsenden Markt für Wasser- und Abwassertechnologien zu rechnen, der auch der deutschen Industrie gute Absatzchancen bietet. Die vorhandenen Stärken der deutschen Wasserwirtschaft auszubauen und deren Innovationsfähigkeit zu fördern, ist daher eine zentrale politische und gesellschaftliche Aufgabe. Dafür muss die derzeitige Forschungs- und Entwicklungsförderung intensiviert und neu justiert werden, wobei auf sehr guten Vorarbeiten aufgebaut werden kann.
Der Islam stellt in Deutschland derzeit die größte religiöse Minderheit dar. Für ein friedliches Zusammenleben und einen Ausgleich zwischen verschiedenen Interessen, stellt das Recht wegen der Möglichkeit der Durchsetzbarkeit einen besonders wichtigen Faktor dar. Gegenstand des Aufsatzes ist die Frage, wie die deutsche Rechtsordnung mit religiösen Konflikten umgeht, inwieweit also die Interessen von Muslimen rechtlich geschützt werden. Dazu werden zunächst die verfassungsrechtlichen Maßstäbe zur Religionsfreiheit darge-stellt und die zentralen Kritikpunkte an der bisher ausgesprochen religionsfreundlichen Rechtsprechung analysiert. Sodann wird die Bedeutung dieser Maßstäbe für drei Einzelfragen näher betrachtet. Behandelt werden zum einen Konfliktfelder durch Religionsausübung in der Schule: das freiwillige Gebet von Schülern in Unterrichtspausen, die Befreiung vom Schwimmunterricht sowie die Kopftuchdebatte. Zum anderen werden die Fragestellungen erörtert, ob und inwieweit Scharia vor deutschen Gerichten Anwendung findet und ob und inwieweit sich innerhalb Deutschlands eine Paralleljustiz entwickelt. Abschließend befasst sich der Aufsatz mit der Beschneidung minderjähriger Jungen aus religiösen Gründen. Dieses Thema hat durch ein Urteil des LG Köln aus dem Jahre 2012 politische Aufmerksamkeit erlangt und schnelle Reaktionen des Gesetzgebers ausgelöst.
The recent financial crisis has demonstrated that a failure of Systemically Important Financial Institutions (SIFIs) could seriously damage the stability of the financial system. A precise and consistent definition of a SIFI is pivotal to ensure efficient and effective regulation of the global financial sector. This paper proposes a threefold test logic that allows to classify Financial Institutions as systemically important across the various industry segments.
Dokumentation von Best-Practice-Beispielen zum Umgang mit dem Fahren ohne (gültigen) Fahrschein
(2016)
In Deutschland und Europa versuchen Verkehrsunternehmen und -verbünde bereits seit längerer Zeit gegen das Fahren ohne (gültigen) Fahrschein vorzugehen, ihre Fahrgeldeinnahmen zu sichern und zu steigern sowie die Quote der Personen, die den ÖPNV ohne (gültiges) Ticket nutzen, zu minimieren. Auf Grundlage des ersten Arbeitspaketes (Literaturanalyse zum Stand der Forschung: Schwerdtfeger et al. 2016) wurden Maßnahmen untersucht, die zum Erreichen der genannten Ziele beitragen. Der Fokus liegt dabei auf Best Practice Beispielen, also Maßnahmen, die in der Praxis als erfolgreich hinsichtlich der Reduzierung des Fahrens ohne (gültigen) Fahrschein sowie hinsichtlich der Einnahmesicherung und -steigerung angesehen werden. Das Ergebnis der Untersuchung ist eine umfangreiche Auseinandersetzung mit Best Practice Beispielen in Bezug auf das Fahren ohne (gültigen) Fahrschein. Außerdem wurden aktuell diskutierte Ansätze alternativer Finanzierungsinstrumente hinsichtlich ihrer Eignung zur Finanzierung des ÖPNV untersucht. Zwar können alternative Finanzierungsinstrumente derzeit noch nicht als Best Practice eingestuft werden, allerdings stehen sie in direkter Beziehung zur Einnahmesicherung im ÖPNV-Sektor.
Das Fahren ohne (gültigen) Fahrschein wird bereits seit den späten 1980er Jahren in der Wissenschaft thematisiert. Bis heute wird das Thema vorwiegend aus einer rechtswissenschaftlichen, einer betriebswirtschaftlichen sowie einer kriminologischen Perspektive betrachtet. Weiterhin wird das Fahren ohne (gültigen) Fahrschein in Ansätzen sozialwissenschaftlich betrachtet. Eine Analyse des Themas aus der Perspektive der sozialwissenschaftlichen Mobilitätsforschung würde den wissenschaftlichen Diskurs erweitern. In den Print- und Onlinemedien wird das Thema ebenfalls relativ häufig thematisiert. Der Forschungsstand spiegelt sich in den Medien wieder, allerdings ist die Auseinandersetzung weitaus differenzierter, da beispielsweise auch politische Motivationen zum Fahren ohne (gültigen) Fahrschein angesprochen werden. Insgesamt lässt sich feststellen, dass Das Fahren ohne (gültigen) Fahrschein bereits Einzug in wissenschaftliche Untersuchungen und Debatten gefunden hat. Das Arbeitspapier fasst den Stand der Forschung zum Fahren ohne (gültigen) Fahrschein zusammen und bildet somit einen Einstieg für die Fokussierung des Themas aus Sicht der sozialwissenschaftlichen Mobilitätsforschung.
Under ordinary circumstances, the fiscal implications of central bank policies tend to be seen as relatively minor and escape close scrutiny. The global financial crisis of 2008, however, demanded an extraordinary response by central banks which brought to light the immense power of central bank balance sheet policies as well as their major fiscal implications. Once the zero lower bound on interest rates is reached, expanding a central bank’s balance sheet becomes the central instrument for providing additional monetary policy accommodation. However, with interest rates near zero, the line separating fiscal and monetary policy is blurred. Furthermore, discretionary decisions associated with asset purchases and liquidity provision, as well as with lender-of-last-resort operations benefiting private entities, can have major distributional effects that are ordinarily associated with fiscal policy. In the euro area, discretionary central bank decisions can have immense distributional effects across member states. However, decisions of this nature are incompatible with the role of unelected officials in democratic societies. Drawing on the response to the crisis by the Federal Reserve and the ECB, this paper explores the tensions arising from central bank balance sheet policies and addresses pertinent questions about the governance and accountability of independent central banks in a democratic society.
Studies employing micro price data suggest that price dispersion is larger between regions in different countries than between regions in the same country. To investigate the strength of this border effect, deviations from the law of one price are used in most studies to provide statistical evidence on the effect of borders on price dispersion. I propose an alternative measure of the economic costs of borders which has an explicit welfare-theoretic foundation. Employing a unique micro price data set from households in Belgium, Germany and the Netherlands I provide evidence on the economic importance of price differences for households. I find that price dispersion within countries has only small economic importance, but that price dispersion between Belgium and Germany (and Belgium and the Netherlands) has considerable economic importance.
Microeconometric evidence on demand-side real rigidity and
implications for monetary non-neutrality
(2016)
To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data set for three European countries, including prices and quantities bought for a large number of goods, in addition to consumer characteristics, we provide estimates of price elasticities of demand and on the degree of demand-side real rigidities. We find that price elasticites of demand are about 4 in the median. Furthermore, we find evidence for demand-side real rigidities. These are, however, much smaller than what is often assumed in macroeconomic models. The median estimate for demand-side real rigidity, the super-elasticity, is in a range between 1 and 2. To quantitatively assess the implications of our empirical estimates, we calibrate a menu-cost model with the estimated super-elasticity. We find that the degree of monetary non-neutrality doubles in the model including demand-side real rigidity, compared to the model with only nominal rigidity, suggesting a multiplier effect of around two. However, the model can explain only up to 6% of the monetary non-neutrality observed in the data, implying that additional multipliers are necessary to match the behavior of aggregate variables.
Using novel monthly data for 226 euro-area banks from 2007 to 2015, we investigate the determinants of changes in banks’ sovereign exposures and their effects during and after the crisis. First, public, bailed out and poorly capitalized banks responded to sovereign stress by purchasing domestic public debt more than other banks, with public banks’ purchases growing especially in coincidence with the largest ECB liquidity injections. Second, bank exposures significantly amplified the transmission of risk from the sovereign and its impact on lending. This amplification of the impact on lending does not appear to arise from spurious correlation or reverse causality.
Klimawandel, demographische Veränderungen, steigende Energiepreise, politische Rahmensetzungen und rechtliche Zielvorgaben erfordern eine Neuausrichtung der siedlungswasserwirtschaftlichen Leistungserbringung. Ziel ist, die Siedlungswasserwirtschaft nachhaltig und zukunftsfähig zu gestalten.
Das vorliegende Papier skizziert zum Thema „Instandhaltung der Wasserinfrastruktur:
finanzielle und organisatorische Spielräume“ Maßnahmen, die eine nachhaltige und zukunftsfähige Ausrichtung der siedlungswasserwirtschaftlicher Praxis unterstützen.
Die Maßnahmen wurden im Projekt im Rahmen von zwei szenariobasierten Planspielworkshops entwickelt. Ausgehend von den Diskussionsergebnissen legt das Papier dar, wo Handlungsmöglichkeiten ansetzen können und gibt zugleich Hinweise für die Umsetzung und Bewertung der vorgestellten Maßnahmen. Der Katalog ist dabei als Anstoß für eine stärkere Integration von Nachhaltigkeit in das unternehmerische Handeln zu verstehen.
Recently there has been an explosion of research on whether the equilibrium real interest rate has declined, an issue with significant implications for monetary policy. A common finding is that the rate has declined. In this paper we provide evidence that contradicts this finding. We show that the perceived decline may well be due to shifts in regulatory policy and monetary policy that have been omitted from the research. In developing the monetary policy implications, it is promising that much of the research approaches the policy problem through the framework of monetary policy rules, as uncertainty in the equilibrium real rate is not a reason to abandon rules in favor of discretion. But the results are still inconclusive and too uncertain to incorporate into policy rules in the ways that have been suggested.
Der Artikel untersucht Rassismus und Sexismus und ihre materiellen und diskursiven Artikulationen an dem spezifischen Artikulationsort Haar, bzw. Locken. Anhand von biographisch-narrativen Interviews mit Frauen of Color und mit Hilfe von Ansätzen der Grounded Theory werden Fragen danach aufgeworfen, welche symbolischen Bedeutungen von Locken es gibt; Welche Umgangsformen mit Haar es gibt; Wie Haar eingesetzt wird; Ob es Widersprüche gibt; Wie sich diese artikulieren und wie Subjekte trotz rassistischer, sexistischer Diskurse und der damit verbundenen materiellen Unterdrückung handlungsmächtige Akteurinnen ihrer eigenen Biographien werden. Parallel wird der Forschungsprozess aus dekolonialer, feministischer Perspektive entwickelt, beschrieben und reflektiert und damit eine dekolonial feministische Methodologie entworfen.
This working paper is based on a lecture given at the Summer School “Multiple Inequalities in the Age of Transnationalization”, June 23-27 2014 at Goethe University Frankfurt. In it, I explore the linkages between sexuality and migration and aim to show that instead of deeming them a narrow subfield of migration studies, thinking through these linkages has much wider implications for different fields, including post- and decolonial queer studies, the study of race and sexuality, the study of citizenship and state projects of inclusion/exclusion, and for work that attempts to ce-center the predominant knowledge production focused on the Global North.
Highly-skilled labour migration in Switzerland: household strategies and professional careers
(2016)
The article investigates household strategies in the context of highly-skilled labour migration. It focuses on the ways highly-skilled migrants are taking up residence in Switzerland. The analysis shows different household strategies based on the perception of a further professional move. The perceived likeliness of a further move implies household strategies characterized by a high motility: the household remains ready to move and mobilises dedicated organisations (like outplacement agencies or international schools). When a further move is neither perceived nor wanted, the household develops more anchored strategies which are often cheaper. In order to cope with frequent mobilities, the analysis shows that household strategies are deeply gendered.
Die Empfehlung des Corporate Governance-Kodex (Ziff. 5.4.2), „dem Aufsichtsrat soll eine nach seiner Einschätzung angemessene Anzahl unabhängiger Mitglieder angehören“, wirft in der Praxis nach wie vor Fragen auf. Im Folgenden sollen einige Thesen zur Auslegung dieser Empfehlung aufgestellt werden. Eine rechtspolitische Auseinandersetzung mit ihr und Änderungsvorschläge sind an dieser Stelle nicht beabsichtigt.
André Prüm has asked me to talk about “La Théorie de l´organe” supposing that this is a German invention. Well, we cannot claim the authorship or copyright for that, but it is true that this doctrine is still dominating German doctrinal thinking in company law. Let me first look at the historical development and background of this theory and then ask for its actual meaning and practical consequences.
Private equity fund managers are typically required to invest their own money alongside the fund. We examine how this coinvestment affects the acquisition strategy of leveraged buyout funds. In a simple model, where the investment and capital structure decisions are made simultaneously, we show that a higher coinvestment induces managers to chose less risky firms and use more leverage. We test these predictions in a unique sample of private equity investments in Norway, where the fund manager's taxable wealth is publicly available. Consistent with the model, portfolio company risk decreases and leverage ratios increase with the coinvestment fraction of the manager's wealth. Moreover, funds requiring a relatively high coinvestment tend to spread its capital over a larger number of portfolio firms, consistent with a more conservative investment policy.
We argue two alternative routes that lead entrepreneurial start-ups to acquisition outcomes instead of liquidation. On one hand, acquisitions can come about through the control route with external financers such as venture capitalists (VCs). VCs take control through their board seats along with other contractual rights that can bring about changes in a start-up necessary to successfully attract a strategic acquirer. Consistent with this view, we show that VCs often replace the founding entrepreneur as CEO long before an acquisition exit. On the other hand, acquisitions can come about through advice and support provided to the start-up, such as that provided by an incubator or technology park. Based on a sample of 251 Crunchbase companies in the U.S. over the years 2007 to 2014, we present evidence that is strongly consistent with these propositions. Further, we show that the data indicate a tension between VC-backing of start-ups resident in technology parks insofar as such start-ups are slower to become, and less likely to be, acquired.
The dynamics of entrepreneurial careers in high-tech ventures: experience, education, and exit
(2016)
We investigate the career dynamics of high-tech entrepreneurs by analyzing the exit choice of entrepreneurs: to found another firm, to become dependently employed, or to act as a business angel. Our detailed data resting on the CrunchBase online database indicate that founders stick with entrepreneurship as a serial entrepreneur or as an angel investor only in cases where the founder (1) had experience either in founding other startups or working for a startup, (2) had a ‘jack-of-all-trades’ education, or (3) achieved substantial financial success upon a venture capital exit transaction.
Little evidence exists on the financing decisions of newly founded firms or on the financing dynamics of these firms over their life cycle. We aim to help filling this gap by investigating the financing dynamics of 2,456 French manufacturing firms founded between 2004 and 2006 through their legally required and reported financial statements. Because we observe significant heterogeneity in the financing decision in the firms' founding year, we focus on analyzing whether these differences widen, persist, or converge by using different convergence concepts. We identify a persistence-cum-convergence pattern. We find the existence of ß-convergence (implying that e.g. firms with lower initial levels of debt accumulate more debt over time) but not of σ-convergence (i.e. we observe an increase in the cross-sectional dispersion of the financing structure). We also show that the dynamics of financing matter for the growth path of the firms.
Of the novelties introduced by digitization in the study of literature, the size of the archive is probably the most dramatic: we used to work on a couple of hundred nineteenth-century novels, and now we can analyze thousands of them, tens of thousands, tomorrow hundreds of thousands. It's a moment of euphoria, for quantitative literary history: like having a telescope that makes you see entirely new galaxies. And it's a moment of truth: so, have the digital skies revealed anything that changes our knowledge of literature? This is not a rhetorical question. In the famous 1958 essay in which he hailed "the advent of a quantitative history" that would "break with the traditional form of nineteenth-century history", Fernand Braudel mentioned as its typical materials "demographic progressions, the movement of wages, the variations in interest rates [...] productivity [...] money supply and demand." These were all quantifiable entities, clearly enough; but they were also completely new objects compared to the study of legislation, military campaigns, political cabinets, diplomacy, and so on. It was this double shift that changed the practice of history; not quantification alone. In our case, though, there is no shift in materials: we may end up studying 200,000 novels instead of 200; but, they're all still novels. Where exactly is the novelty?
Das Leistungsfähigkeitsprinzip als zentraler Grundsatz der Einkommensbesteuerung ist in hohem Maße konkretisierungsbedürftig und damit für Wertentscheidungen offen. Diese Offenheit wird von der traditionellen Steuerrechtswissenschaft mit Wertungen gefüllt, die aus der Perspektive der Geschlechtergerechtigkeit äußerst problematisch sind. In diesem Aufsatz werden zunächst Einnahmenseite und Ausgabenseite des Einkommens für die Bemessung der Leistungsfähigkeit betrachtet. Dabei wird aufgezeigt, dass die fehlende Berücksichtigung der Reproduktionsarbeit in Kombination mit dem Ehegattensplitting auf Seite der Einnahmen das Leistungsfähigkeitsprinzip erheblich verzerrt und die Verweigerung der vollen Absetzbarkeit von Kinderbetreuungskosten beispielsweise auf Seite der Ausgaben das traditionelle Familienmodell weiterhin begünstigt. Einem solchen Steuerrecht, das die Genderperspektive systematisch ausblendet, stehen aber Verfassungsnormen entgegen, die im Folgenden anhand der argumentativen Leitlinien skizziert werden. Daher muss das Steuerrecht weiter entwickelt und an die verfassungsrechtlichen Anforderungen an Gleichberechtigung von Mann und Frau gekoppelt werden.
In the wake of the recent financial crisis, significant regulatory actions have been taken aimed at limiting risks emanating from banks’ trading activities. The goal of this paper is to look at the alternative reforms in the US, the UK and the EU, specifically with respect to the role of proprietary trading. Our conclusions can be summarized as follows: First, the focus on a prohibition of proprietary trading, as reflected in the Volcker Rule in the US and in the current proposal of the European Commission (Barnier proposal), is inadequate. It does not necessarily reduce risk-taking and it is likely to crowd out desired trading activities, thereby possibly affecting financial stability negatively. Second, trading separation into legally distinct or ring-fenced entities within the existing banking organizations, as suggested under the Vickers Report for the UK and the Liikanen proposal for the EU, is a more effective solution. Separation limits cross-subsidies between banking and proprietary trading and diminishes contagion risk, while still allowing for synergies and risk management across banking, non-proprietary trading and proprietary trading.
We study the impact of higher capital requirements on banks’ balance sheets and its transmission to the real economy. The 2011 EBA capital exercise provides an almost ideal quasi-natural experiment, which allows us to identify the effect of higher capital requirements using a difference-in-differences matching estimator. We find that treated banks increase their capital ratios not by raising their levels of equity, but by reducing their credit supply. We also show that this reduction in credit supply results in lower firm-, investment-, and sales growth for firms which obtain a larger share of their bank credit from the treated banks.
We employ a unique dataset on members of an elite service club in Germany to investigate how elite networks affect the allocation of resources. Specifically, we investigate credit allocation decisions of banks to firms inside the network. Using a quasi-experimental research design, we document misallocation of bank credit inside the network, with state-owned banks engaging most actively in crony lending. The aggregate cost of credit misallocation amounts to 0.13 percent of annual GDP. Our findings, thus, resonate with existing theories of elite networks as rent extractive coalitions that stifle economic prosperity.
The euro crisis was fueled by the diabolic loop between sovereign risk and bank risk, coupled with cross-border flight-to-safety capital flows. European Safe Bonds (ESBies), a union-wide safe asset without joint liability, would help to resolve these problems. We make three contributions. First, numerical simulations show that ESBies would be at least as safe as German bunds and approximately double the supply of euro safe assets when protected by a 30%-thick junior tranche. Second, a model shows how, when and why the two features of ESBies — diversification and seniority — can weaken the diabolic loop and its diffusion across countries. Third, we propose a step-by-step guide on how to create ESBies, starting with limited issuance by public or private-sector entities.
Die dynamische Entwicklung im Bereich neuer Mobilitätsdienstleistungen hat dazu geführt, dass der städtische Mobilitätsmarkt von einer hohen Dynamik und einer Vielzahl neuer Akteure gekennzeichnet ist. Smartphones und mobiles Internet unterstützen die neuen Angebote wie flexibles, stationäres oder Peer-to-Peer-Carsharing sowie Mitnahme- und Fahrradverleihsysteme. Die neuen Angebote reagieren auf eine veränderte Nachfrage, generieren aber wiederum auch neue Nutzungsmuster. Kommunale und regionale Akteure stehen vor der Aufgabe, auf die neuen Herausforderungen, die sich in räumlichen und politischen Konflikten niederschlagen können, zu reagieren. Die vorliegende Studie zeigt auf Basis einer Bestandsaufnahme von Sharing-Systemen in der Region FrankfurtRheinMain Handlungsoptionen für Vertreter aus Politik und Verwaltung auf, um die neuen Angebote im Sinne einer nachhaltigen Verkehrs- und Stadtentwicklung zu integrieren. Dabei zeigt sie zunächst die Chancen und Herausforderungen auf, die sich aus den jüngsten Entwicklungen ergeben. Anschließend folgt eine ausführliche Bestandsaufnahme, die sich in sechs Handlungsfelder gliedert: Fahrradverleihsysteme, Carsharing, Mitnahmeangebote und Mitfahrparkplätze, Verknüpfung des öffentlichen Verkehrs mit multimodalen Angeboten, multimodale Mobilitätsapps und -plattformen sowie Parken. Dabei werden Aussagen zu Angebotsformen, verkehrlichen und ökologischen Wirkungen sowie zu regionalen Entwicklungen getroffen. Anschließend werden auf Basis vorhandener Untersuchungen und im Rahmen des Projekts durchgeführter Fokusgruppen Nutzungsmuster, Bekanntheit und Attraktivität von Sharing-Systemen dargestellt. Die Handlungsempfehlungen wurden in mehreren Workshops mit regionalen Praxisakteuren aus den Bereichen Stadtverwaltung, Carsharing, Verkehrsverbund, Fahrradverleihsysteme, Mitfahrangebote etc. und vertiefenden Expertengesprächen entwickelt.
Die Globalisierung hat nicht, wie es sowohl ordoliberale als auch kritische Theorien einer globalen „economic constitution“ erwarten, eine einheitliche Weltwirtschaftsverfassung hervorgebracht, sondern eine fragmentierte Kollisionsverfassung, d.h. eine Metaverfassung von Verfassungskonflikten. Als deren kollidierende Einheiten fungieren nicht mehr die Nationalstaaten, sondern transnationale Produktionsregimes. Die von Böhm und Sinzheimer für den Nationalstaat formulierte Alternative von ordoliberaler Wirtschaftsverfassung und sozialdemokratischer Wirtschaftsdemokratie ist in der transnationalen Wirtschaftsverfassung vom Gegensatz zwischen den neokorporatistisch organisierten Produktionsregimes Kontinentaleuropas und den finanzkapitalistisch geprägten Produktionsregimes anglo-amerikanischer Prägung, abgelöst worden. Entgegen allen Voraussagen haben die neo-korporatistischen Wirtschaftsverfassungen Kontinentaleuropas trotz Globalisierung und Wirtschaftskrise eine erstaunliche Resilienz bewiesen. Einer wirtschaftsdemokratischen Konstitutionalisierung eröffnen sich hier neue Chancen dadurch, dass, wie am Beispiel der Corporate Codes gezeigt wird, unternehmensexterne gesellschaftliche Kräfte, also neben staatlichen Interventionen rechtliche Normierungen und „zivilgesellschaftliche“ Gegenmacht aus anderen Kontexten so massiven Druck auf die Unternehmen ausüben, dass sie gezwungen sind, gemeinwohlbezogene Selbstbeschränkungen aufzubauen.
Prozesse der Konstitutionalisierung jenseits des Nationalstaates ver-laufen in zwei unterschiedlichen Richtungen: in transnationalen Politikprozessen jenseits der Nationalstaatsverfassungen, gleichzeitig außerhalb der internationalen Politik in den “privaten” Sektoren der Weltgesellschaft. Die Verfassungssoziologie, die solche Prozesse analysiert, distanziert sich damit von den Verengungen des traditionellen Konstitutionalismus auf den Nationalstaat und fokussiert gesellschaftliche Verfassungen im nationalen und transnationalen Raum. Doch was ist das Gesellschaftliche im gesellschaftlichen Konstitutionalismus? Dies ist aktuell Gegenstand einer vielstimmigen Kontroverse über die Subjekte nichtstaatlicher Verfassungen, ihren Ursprung, ihre Legitimation, ihre Reichweite und ihre inneren Strukturen. Der Beitrag versteht die Kontroverse als „Thema mit Variationen“ und stellt folgende Leitfragen an die zahlreichen Variationen: Was ist in der einzelnen Variation das jeweilige „Kompositionsprinzip“? Welche Schwierigkeiten zeigen sich in dessen Durchführung? Welches sind seine aufhebenswerten Motive? In diesem Sinn wird zunächst das von David Sciulli vorgegebene Thema des gesellschaftlichen Konstitutionalismus kurz vorgestellt. Dann werden sechs Variationen in zwei unterschiedlichen Variationsreihen vorgeführt, einer ersten, die Konstitutionalisierung als Expansion einer einzigen Rationalität in alle gesellschaftlichen Bereiche versteht, einer zweiten, welche trotz der Pluralität des gesellschaftlichen Konstitutionalismus auf der Einheit der Verfassung besteht. Im Schlussteil nehmen drei weitere Variationen schließlich die Motive, die sich als aufhebenswert herausgestellt haben – Meta-Verfassung, Nomos und Narrativ, mediale Reflexivität - wieder auf und entwickeln sie weiter.
Constitutionalization beyond the nation state can be observed as an evolutionary process that leads in two quite different directions: (1) constitutions evolve in transnational political processes outside the nation state; (2) simulta-neously, constitutions evolve outside international politics in global society’s ‘private’ sectors. What, however, is the specifically societal element in societal constitutionalism? This is currently the object of a controversy regarding the subjects of non-state constitutions, their origin, their legitimization, their scope, and their internal structures. This article interprets the controversy as a theme with a number of variations. What is the distinctive ‘compositional principle’ in each particular variation? Which problems become evident in its ‘development’? What are its most valuable ‘motifs’? The article starts with David Sciulli’s theme of societal constitutionalism. Then it presents six variations on Sciulli. In a first group, constitutionalization is perceived as the expansion of a single rationality into all spheres of society. In a second group, the motif of the unity of the consti-tution can still be heard, despite the essential pluralism of societal constitution-alism. In the final movement, three further variations will then reprise and devel-op further the most important motifs, in a resumption of the original theme.
The eurozone remains in a deep, largely macro-economic crisis. A robust global economy and falling oil prices have supported Europe’s economy for some time, but by now it is clear that the eurozone will only be able to pull itself out of this crisis by means of more decisive action. One response, the recent easing of monetary policy by the European Central Bank (ECB), has, for the most part, been sharply and one-sidedly criticised in Germany. Monetary policy inaction seems to be the preferred option of many in Germany.
The authors discuss the following question: What would happen if the ECB failed to respond to the excessively low inflation and the weak economy? And what economic policy would be suitable under the current circumstances, if not monetary policy?
Steueroasen besitzen drei wichtige Merkmale, die aus der Sicht von Steuerhinterziehern und Steuervermeidern anderer Länder besondere Anziehungskraft haben. Sie bieten niedrige Steuersätze für alle oder für bestimmte Kapitaleinkommen. Sie weisen eine hohe politische Stabilität und funktionierende Institutionen auf. Schließlich verbinden sie dies mit einem hohen Maß an faktischer Intransparenz in den Besitzstrukturen von Briefkastenfirmen sowie einer ausgeprägten Vertraulichkeit von Bankdaten. Unter Führung der OECD hat sich in den letzten Jahren der politische Druck auf die internationalen Steueroasen erhöht und zu einer Reihe von bilateralen und multilateralen Abkommen zum Informationsaustausch geführt. Da diese Abkommen nicht alle Steueroasen umfassen, haben sie die Gesamtanlagen in den Steueroasen allerdings bisher nur in sehr geringem Umfang reduzieren können. In Deutschland werden die internationalen Abkommen der letzten Jahre von Seiten der Steuerpolitik aber bereits als Erfolg verbucht und eine stärker progressive Besteuerung von Kapitaleinkünften diskutiert. Falls weiterhin ein Teil der einschlägigen Steueroasen dem Informationsaustausch fernbleibt, bietet es sich an, auf bilateralem Wege Verhandlungen aufzunehmen oder den Druck über multilaterale Verfahren und Sanktionen zu erhöhen.
Das Ergebnis des Volksentscheids im Vereinigten Königreich ist ein Weckruf. Alle Entscheidungsträger der Europäischen Union und ihrer Mitgliedstaaten sind aufgerufen, grundlegende Reformen der Verfassung einer Europäischen Union, möglicherweise nur noch einer europäischen „Kontinentalunion“ unverzüglich in Angriff zu nehmen. Unverzüglich bedeutet, einen Reformprozess nicht erst dann zu beginnen, wenn die Verhandlungen über ein Austrittsabkommen beendet worden sind. Eine Rückentwicklung der Europäischen Union zu einer bloßen Wirtschaftsgemeinschaft dürfte dabei keine Lösung sein. Es ist jetzt angezeigt, offen und – notfalls kontrovers – zu diskutieren, wie ein künftiger Bundesstaat auf europäischer Ebene aussehen könnte.
Mis-selling by banks has occurred repeatedly in many nations over the last decade. While clients may benefit from competition – enabling them to choose financial services at lowest costs – economic frictions between banks and clients may give rise to mis-selling. Examples of mis-selling are mis-representation of information, overly complex product design and non-customized advice. European regulators address the problem of mis-selling in the "Markets in Financial Instruments Directive" (MiFID) I and II and the "Markets in Financial Instruments Regulation" (MiFIR), by setting behavioral requirements for banks, regulating the compensation of employees, and imposing re-quirements on offered financial products and disclosure rules.
This paper argues that MiFID II protects clients but is not as effective as it could be. (1) It does not differentiate between client groups with different levels of financial literacy. Effective advice requires different advice for different client groups. (2) MiFID II uses too many rules and too many instruments to achieve identical goals and thereby generates excessive compliance costs. High compliance costs and low revenues would drive banks out of some segments of retail business.
We show that the net corporate payout yield predicts both the stock market index and house prices and that the log home rent-price ratio predicts both house prices and labor income growth. We incorporate the predictability in a rich life-cycle model of household decisions involving consumption of both perishable goods and housing services, stochastic and unspanned labor income, stochastic house prices, home renting and owning, stock investments, and portfolio constraints. We find that households can significantly improve their welfare by optimally conditioning decisions on the predictors. For a modestly risk-averse agent with a 35-year working period and a 15-year retirement period, the present value of the higher average life-time consumption amounts to roughly $179,000 (assuming both an initial wealth and an initial annual income of $20,000), and the certainty equivalent gain is around 5.5% of total wealth (financial wealth plus human capital). Furthermore, every cohort of agents in our model would have benefited from applying predictor-conditional strategies along the realized time series over our 1960-2010 data period.
Most defined contribution pension plans pay benefits as lump sums, yet the US Treasury has recently encouraged firms to protect retirees from outliving their assets by converting a portion of their plan balances into longevity income annuities (LIA). These are deferred annuities which initiate payouts not later than age 85 and continue for life, and they provide an effective way to hedge systematic (individual) longevity risk for a relatively low price. Using a life cycle portfolio framework, we measure the welfare improvements from including LIAs in the menu of plan payout choices, accounting for mortality heterogeneity by education and sex. We find that introducing a longevity income annuity to the plan menu is attractive for most DC plan participants who optimally commit 8-15% of their plan balances at age 65 to a LIA that starts paying out at age 85. Optimal annuitization boosts welfare by 5-20% of average retirement plan accruals at age 66 (assuming average mortality rates), compared to not having access to the LIA. We also compare the optimal LIA allocation versus two default options that plan sponsors could implement. We conclude that an approach where a fixed fraction over a dollar threshold is invested in LIAs will be preferred by most to the status quo, while enhancing welfare for the majority of workers.
We designed and fielded an experimental module in the 2014 HRS which seeks to measure older persons’ willingness to voluntarily defer claiming of Social Security benefits. In addition we evaluate the stated willingness of older individuals to work longer, depending on the Social Security incentives offered to delay claiming their benefits. Our project extends previous work by analyzing the results from our HRS module and comparing findings from other data sources, which included very much smaller samples of older persons. We show that half of the respondents would delay claiming if no work requirement were in place under the status quo, and only slightly fewer, 46 percent, with a work requirement. We also asked respondents how large a lump sum they would need with or without a work requirement. In the former case, the average amount needed to induce delayed claiming was about $60,400, while when part-time work was required, the average was $66,700. This implies a low utility value of leisure foregone of only $6,300, or about 10 percent of older households’ income.
In this chapter, I examine the relationship between customary international law and general principles of law. Both are distinct sources of public international law (Art. 38(1)(b) and (c) of the Statue of the International Court of Justice). In a first step, I analyze the different meanings of principles as a “source” of international law. Second, I consider different approaches to principles as a norm type in legal theory. Third, I discuss attempts in international legal doctrine to facilitate conceptual issues by either unifying general principles as a source with the source of customary international law or by equating general principles as a source and as a norm type. Finally, I propose that the delimitation between customary international law and general principles of law as sources of international law should follow the distinction between situations dominated by factual reciprocity (which justify customary norms) and situations where such factual reciprocity is absent (which justify general principles). The jurisgenerative processes leading to the emergence of general principles of international law are processes of changing identities and argumentative self-entrapment.
The old boy network: the impact of professional networks on remuneration in top executive jobs
(2016)
We investigate the impact of social networks on earnings using a dataset of over 20,000 senior executives of European and US firms. The size of an individual's network of influential former colleagues has a large positive association with current remuneration. An individual at the 75th percentile in the distribution of connections could expect to have a salary nearly 20 per cent higher than an otherwise identical individual at the median. We use a placebo technique to show that our estimates reflect the causal impact of connections and not merely unobserved individual characteristics. Networks are more weakly associated with women's remuneration than with men's. This mainly reflects an interaction between unobserved individual characteristics and firm recruitment policies. The kinds of firm that best identify and advance talented women are less likely to give them access to influential networks than are firms that do the same for the most talented men.
Schätzwerte mittelfristiger Gleichgewichtszinsen mit der Methode nach Laubach und Williams (2003) werden inzwischen vielfach in der Diskussion um die Geld- und Fiskalpolitik zitiert. Unter anderem wurden sie von Summers (2014a) als Evidenz für eine säkulare Stagnation angeführt und von Yellen (2015) zur Rechtfertigung der Nullzinspolitik verwendet. In diesem Papier nehmen wir eine umfangreiche Untersuchung und Sensitivitätsanalyse dieser Schätzwerte für die Vereinigten Staaten, Deutschland und den Euro-Raum vor. Aufgrund der hohen Unsicherheit und Sensitivität, die mit den Schätzwerten mittelfristiger Gleichgewichtszinsen mit der Laubach-Williams-Methode und ähnlichen Ansätzen verbunden ist, sollten diese Schätzungen nicht den Ausschlag für entscheidende Weichenstellungen in der Geld- und Fiskalpolitik geben.
This paper compares the dynamics of the financial integration process as described by different empirical approaches. To this end, a wide range of measures accounting for several dimensions of integration is employed. In addition, we evaluate the performance of each measure by relying on an established international finance result, i.e., increasing financial integration leads to declining international portfolio diversification benefits. Using monthly equity market data for three different country groups (i.e., developed markets, emerging markets, developed plus emerging markets) and a dynamic indicator of international portfolio diversification benefits, we find that (i) all measures give rise to a very similar long-run integration pattern; (ii) the standard correlation explains variations in diversification benefits as well or better than more sophisticated measures. These Findings are robust to a battery of robustness checks.
his paper examines whether investor mood, driven by World Health Organization (WHO) alerts and media news on globally dangerous diseases, is priced in pharmaceutical companies' stocks in the United States. We concentrate on irrational investors who buy and sell pharmaceutical companies' stocks guided by beliefs as opposed to rational expectations. We argue that disease-related news (DRNs) should not trigger rational trading. We find that DRNs have a positive and significant sentiment effect among investors (on Wall Street). The effect is stronger (weaker) for small (large) companies, who are less (more) likely to engage in the development of new vaccines in the wake of DRNs. A potential negative mood (on Main Street) – induced by disease related fear – does not alter the positive sentiment effect. Our findings give rise to profitable trading strategies leading to significantly positive performances. Overall, this unparalleled research shows that large events of devastating nature to the economy can be considered as good news to some groups of interest, such as stock market traders.
