A stochastic forward-looking model to assess the profitability and solvency of European insurers
(2016)
In this paper, we develop an analytical framework for conducting forward-looking assessments of profitability and solvency of the main euro area insurance sectors. We model the balance sheet of an insurance company encompassing both life and non-life business and we calibrate it using country level data to make it representative of the major euro area insurance markets. Then, we project this representative balance sheet forward under stochastic capital markets, stochastic mortality developments and stochastic claims. The model highlights the potential threats to insurers solvency and profitability stemming from a sustained period of low interest rates particularly in those markets which are largely exposed to reinvestment risks due to the relatively high guarantees and generous profit participation schemes. The model also proves how the resilience of insurers to adverse financial developments heavily depends on the diversification of their business mix. Finally, the model identifies potential negative spillovers between life and non-life business thorugh the redistribution of capital within groups.
Households buy life insurance as part of their liquidity management. The option to surrender such a policy can serve as a buffer when a household faces a liquidity need. In this study, we investigate empirically which individual and household specific sociodemographic factors influence the surrender behavior of life insurance policyholders. Based on the Socio-Economic Panel (SOEP), an ongoing wide-ranging representative longitudinal study of around 11,000 private households in Germany, we construct a proxy to identify life insurance surrender in the data. We use this proxy to conduct fixed effect regressions and support the results with survival analyses. We find that life events that possibly impose a liquidity shock to the household, such as birth of a child and divorce increase the likelihood to surrender an existing life insurance policy for an average household in the panel. The acquisition of a dwelling and unemployment are further aspects that can foster life insurance surrender. Our results are robust with respect to different models and hold conditioning on region specific trends; they vary however for different age groups. Our analyses contribute to the existing literature supporting the emergency fund hypothesis. The findings obtained in this study can help life insurers and regulators to detect and understand industry specific challenges of the demographic change.
In this paper I assess the effect of interest rate risk and longevity risk on the solvency position of a life insurer selling policies with minimum guaranteed rate of return, profit participation and annuitization option at maturity. The life insurer is assumed to be based in Germany and therefore subject to German regulation as well as to Solvency II regulation. The model features an existing back book of policies and an existing asset allocation calibrated on observed data, which are then projected forward under stochastic financial markets and stochastic mortality developments. Different scenarios are proposed, with particular focus on a prolonged period of low interest rates and strong reduction in mortality rates. Results suggest that interest rate risk is by far the greatest threat for life insurers, whereas longevity risk can be more easily mitigated and thereby is less detrimental. Introducing a dynamic demand for new policies, i.e. assuming that lower offered guarantees are less attractive to savers, show that a decreasing demand may even be beneficial for the insurer in a protracted period of low interest rates. Introducing stochastic annuitization rates, i.e. allowing for deviations from the expected annuitization rate, the solvency position of the life insurer worsen substantially. Also profitability strongly declines over time, casting doubts on the sustainability of traditional life business going forward with the low interest rate environment. In general, in the proposed framework it is possible to study the evolution over time of an existing book of policies when underlying financial market conditions and mortality developments drastically change. This feature could be of particular interest for regulatory and supervisory authorities within their financial stability mandate, who could better evaluate micro- and macro-prudential policy interventions in light of the persistent low interest rate environment.
The modern tontine: an innovative instrument for longevity risk management in an aging society
(2016)
The changing social, financial and regulatory frameworks, such as an increasingly aging society, the current low interest rate environment, as well as the implementation of Solvency II, lead to the search for new product forms for private pension provision. In order to address the various issues, these product forms should reduce or avoid investment guarantees and risks stemming from longevity, still provide reliable insurance benefits and simultaneously take account of the increasing financial resources required for very high ages. In this context, we examine whether a historical concept of insurance, the tontine, entails enough innovative potential to extend and improve the prevailing privately funded pension solutions in a modern way. The tontine basically generates an age-increasing cash flow, which can help to match the increasing financing needs at old ages. However, the tontine generates volatile cash flows, so that - especially in the context of an aging society - the insurance character of the tontine cannot be guaranteed in every situation. We show that partial tontinization of retirement wealth can serve as a reliable supplement to existing pension products.
Common systemic risk measures focus on the instantaneous occurrence of triggering and systemic events. However, systemic events may also occur with a time-lag to the triggering event. To study this contagion period and the resulting persistence of institutions' systemic risk we develop and employ the Conditional Shortfall Probability (CoSP), which is the likelihood that a systemic market event occurs with a specific time-lag to the triggering event. Based on CoSP we propose two aggregate systemic risk measures, namely the Aggregate Excess CoSP and the CoSP-weighted time-lag, that reflect the systemic risk aggregated over time and average time-lag of an institution's triggering event, respectively. Our empirical results show that 15% of the financial companies in our sample are significantly systemically important with respect to the financial sector, while 27% of the financial companies are significantly systemically important with respect to the American non-financial sector. Still, the aggregate systemic risk of systemically important institutions is larger with respect to the financial market than with respect to non-financial markets. Moreover, the aggregate systemic risk of insurance companies is similar to the systemic risk of banks, while insurers are also exposed to the largest aggregate systemic risk among the financial sector.

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.
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?
This working paper gives insights on a theoretical perspective on class formation in the context of global financial markets and presents first empirical findings regarding the formation of a global financial class. It draws on numerous encounters with financial professionals that were inter- viewed in Frankfurt (Germany) and Sydney (Australia). As a preliminary conclusion from those inves- tigations on a micro-perspective, we state that acting on the market creates a sense of global socia- bility, whereby organizations only play a secondary role. Careers in finance follow internationally homogenized pathways. This process of global class formation is taking place prominently in global financial centers. Therefore we link the level of investigation on a micro-perspective (experience of financial professionals) with global city life and the fabric of the city. This results in empirical findings on a meso-level from an ethnography of the social and professional urban environment of finance in the two global cities. Symbolic struggles engraved in the built environment of Frankfurt and Sydney are traced and discussed against the background of every-day-practices of aspiration in the financial districts investigated.
Sozialräume der Global Financial Class : Untersuchungen in den Finanzzentren Frankfurt und Sydney
(2016)
Dieses Working Paper untersucht die Bedeutung von Global Cities für die Formierung einer globalen Finanzklasse anhand der Finanzzentren Frankfurt und Sydney. In einer vergleichenden Ethnographie dieser beiden Städte werden urbane Räume und soziale Kontexte erforscht, die durch die kulturellen Praktiken und stilistischen Gemeinsamkeiten der modernen Finanzklasse geprägt sind. Es werden dabei vier charakteristische kulturelle Muster identifiziert: Dies sind die Muster der Repräsentation, der Exklusivität, der Aspiration und der sozialen Durchlässigkeit.
Im Muster der Repräsentation verbindet sich das Finanzwesen auf eine symbolische Weise mit Politik und Gesellschaft, während im Muster der Exklusivität der Kern ökonomischer Praktiken dem Zugriff der Allgemeinheit entzogen wird. Das Muster der Aspiration ermöglicht Praktiken der Herstellung und des Austestens von Zugehörigkeit, während der Modus sozialer Durchlässigkeit eine Auseinandersetzung mit anderen gesellschaftlichen Gruppen und die Aufnahme fremder kultureller Muster durch Praktiken der cultural omnivorousness ermöglicht.
Die Praktiken, die diese vier typischen Muster konstituieren, nehmen dabei jeweils lokale Eigenhei- ten auf, die in einen global verlaufenden Klassenbildungsprozess eingespeist werden und diese glo- bale Klasse in den Städten verankern.
Die "Digitalisierung" ist ein gesamtgesellschaftlicher und globaler Trend, der nahezu alle Bereiche der Lebens- und Arbeitswelt durchzieht und insofern auch das Studieren an (allen) Hochschulen betrifft. Das Schlagwort "Digitalisierung" verweist auch auf alle Varianten der Nutzung von digitalen Technologien im Bereich Studium und Lehre. Lange Zeit stand vor allem das E-Learning im Vordergrund der Diskussion und damit die Nutzung von digitalen Technologien im engeren Lehr-Lernkontext zur Unterstützung der Interaktion von Lehrenden und Studierenden. Heute werden an den Hochschulen zunehmend die weiteren Möglichkeiten der digitalen Technik für Studium und Lehre erkannt und immer mehr in der Praxis an Hochschulen genutzt: Von der Werbung um Studierende bis hin zur Ansprache von Alumni können sie die Qualität, die Leistungsfähigkeit, die Öffnung, Vermarktung und Internationalisierung der Hochschullehre unterstützen (Kerres 2013, Bischof und von Stuckrad 2013); und einige Hochschulen nutzen die Digitalisierung von Lehre und Studium zur Profilbildung und zur besseren Positionierung im nationalen und internationalen Wettbewerb zwischen Hochschulen. ...
Transforming the current rather centralized electricity generating system into a climate neutral system based on renewable energy is an important approach to reduce greenhouse gas emissions and thus mitigate climate change. Stakeholders have each of them their own perception of the best strategies to achieve such a transformation. All perspectives are equally legitimate and needed for developing a specific transformation strategy suited for the region in focus....
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 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 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 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.
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.
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.
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 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).
Der vorliegende Text ist ein Bericht über die Ergebnisse einer qualitativen empirischen Befragung, die im Herbst 2015 in Haushalten eines Quartiers der Stadt Qingdao in China im Rahmen des BMBF-Projekts SEMIZENTRAL durchgeführt wurde. Das Gesamtprojekt umfasst die erstmalige Realisierung eines Resource Recovery Centers (RRC) als flexibles System mit Wasserrückgewinnung und Wiederverwertung in einer schnell wachsenden Stadt. Das Fachgebiet Abwassertechnik am Institut IWAR der Technischen Universität Darmstadt leitet das Projekt. 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 und Abwasser durch die Bewohner und Bewohnerinnen zu erfassen. Thematischer Schwerpunkt der Befragung war, welche Alltagspraxis in Bezug auf Wasser und Abwasser die Bewohnerinnen und Bewohner haben und wie sich diese durch den Umzug aus einer traditionellen Dorfstruktur in ein modernes Wohnquartier verändert hat. Gleichzeitig sollte die Bekanntheit und Akzeptanz des Konzepts des RRC empirisch untersucht werden.
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 develop a model that endogenizes the manager's choice of firm risk and of inside debt investment strategy. Our model delivers two predictions. First, managers have an incentive to reduce the correlation between inside debt and company stock in bad times. Second, managers that reduce such a correlation take on more risk in bad times. Using a sample of U.S. public firms, we provide evidence consistent with the model's predictions. Our results suggest that the weaker link between inside debt and company stock in bad times does not translate into a mitigation of debt-equity conflicts.
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.
In a field study with more than 1.500 customers of an online-broker we test what happens when investors receive repeated feedback on their investment success in a monthly securities account report. The reports show investors’ last year’s returns, costs, their current level of risk and their portfolio diversification. We find that receiving a report results in investors trading less, diversifying more and having higher risk-adjusted returns. Results are robust to controlling for potential play money accounts and changes in report designs. We also find that investors who are less likely to subscribe equally benefit from the report.
It is commonly believed that the response of the price of corn ethanol (and hence of the price of corn) to shifts in biofuel policies operates in part through market expectations and shifts in storage demand, yet to date it has proved difficult to measure these expectations and to empirically evaluate this view. We utilize a recently proposed methodology to estimate the market’s expectations of the prices of ethanol, unfinished motor gasoline and crude oil at horizons from three months to one year. We quantify the extent to which price changes were anticipated by the market, the extent to which they were unanticipated, and how the risk premium in these markets has evolved. We show that the Renewable Fuel Standard (RFS) is likely to have increased ethanol price expectations by as much $1.45 in the year before and in the year after the implementation of the RFS had started. Our analysis of the term structure of expectations provides support for the view that a shift in ethanol storage demand starting in 2005 caused an increase in the price of ethanol. There is no conclusive evidence that the tightening of the RFS in 2008 shifted market expectations, but our analysis suggests that policy uncertainty about how to deal with the blend wall raised the risk premium in the ethanol futures market in mid-2013 by as much as 50 cents at longer horizons. Finally, we present evidence against a tight link from ethanol price expectations to corn price expectations and hence to storage demand for corn in 2005-06.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
„Corporate groups are a fact of life“.1 This was the starting point for a group of renowned European experts to deliver a report on a possible Directive on corporate group law in 2000.2 We all know that no such Directive has been issued.3 However, these days a fresh group of eminent experts has started, among other things, to develop an initiative „on groups of companies“.4 One reason for a European regulation to take its time might be the enormous national differences in dealing with group situations. While some countries, notably the UK,5 rely on general company law to deal with corporate groups, others provide most detailed rules specifically for groups of companies.6 German law provides an example for the latter. Do we need a law of corporate groups? Most countries regulate one or another aspect of group law.7
This is probably most common for tax and for accounting law. Insolvency law will often take group situations into account and the same is true for labour law. Regulatory oversight for financial institutions or insurance companies usually includes a group dimension. Competition law necessarily does so as well. However, in what follows when we speak about „group law“ we will focus on regulation more specifically tuned to genuine questions of company law such as the protection of minority shareholders or creditors, the standards for managerial behavior and the „enabling“ function of legal structures.
Die Krisenproteste in Frankfurt am Main und insb. das Blockupy-Bündnis und dessen Praxen zwischen 2012 und 2015 stehen im Mittelpunkt der folgenden Auseinandersetzung. Insgesamt stellt Blockupy den wohl breitesten Versuch dar, in Deutschland Widerstand gegen das „europäische Krisenregime“ zu organisieren. Hierfür trat das Bündnis 2012 und 2013 mit Aktionen des zivilen Ungehorsams in Frankfurt, im Mai 2014 mit dezentralen Aktionen in ganz Europa sowie der Mobilisierung gegen die Eröffnungsfeier des Neubaus der EZB im Frankfurter Ostend 2015 in Erscheinung. In dichter Form werden die Ereignisse skizziert und abschließend bewertet. Zentralgestellt werden in der Auseinandersetzung mit Blockupy dessen Praxen des Widerspruchs, die Aktionsformen sowie die Prozesse der Bündnisbildung. Gefragt wird nach Blockupys Organisation, den vollzogenen Lernprozessen sowie den inhaltlichen und praxisbezogenen Verschiebungen. Herausgearbeitet wird, dass Blockupy zunächst stark auf die Kritik an „Banken und Konzernen“ abzielte, dann aber immer expliziter auf die EZB fokussierte und eine antikapitalistische Position entwickelte. Immer stärker wird auch die internationale Ausrichtung des Bündnisses, womit die Zielsetzung der Etablierung eines ‚Europas von unten‘ entgegen der ‚autoritären EU von oben‘ einherging.
