This paper contributes to the ongoing debate on the relationship between austerity measures and economic growth. We propose a general equilibrium model where (i) agents have recursive preferences; (ii) economic growth is endogenously driven by investments in R&D; (iii) the government is committed to a zero-deficit policy and finances public expenditures by means of a combination of labor taxes and R&D taxes. We find that austerity measures that rely on reducing resources available to the R&D sector depress economic growth both in the short- and long-run. High debt EU members are currently implementing austerity measures based on higher taxes and/or lower investments in the R&D sector. This casts some doubts on the real ability of these countries to grow over the next years.
The implications of delegating fiscal decision making power to sub-national governments has become an area of significant interest over the past two decades, in the expectation that these reforms will lead to better and more efficient provision of public goods and services. The move towards decentralization has, however, not been homogeneously implemented on the revenue and expenditure side: decentralization has materialized more substantially on the latter than on the former, creating "vertical fiscal imbalances". These imbalances measure the extent to which sub-national governments’ expenditures are financed through their own revenues. This mismatch between own revenues and expenditures may have negative consequences for public finances performance, for example by softening the budget constraint of sub-national governments. Using a large sample of countries covering a long time period from the IMF’s Government Finance Statistics Yearbook, this paper is the first to examine the effects of vertical fiscal imbalances on fiscal performance through the accumulation of government debt. Our findings suggest that vertical fiscal imbalances are indeed relevant in explaining government debt accumulation, and call for a degree of caution when promoting fiscal decentralization.
We develop a model of managerial compensation structure and asset risk choice. The model provides predictions about how inside debt features affect the relation between credit spreads and compensation components. First, inside debt reduces credit spreads only if it is unsecured. Second, inside debt exerts important indirect effects on the role of equity incentives: When inside debt is large and unsecured, equity incentives increase credit spreads; When inside debt is small or secured, this effect is weakened or reversed. We test our model on a sample of U.S. public firms with traded CDS contracts, finding evidence supportive of our predictions. To alleviate endogeneity concerns, we also show that our results are robust to using an instrumental variable approach.

The Eurozone fiscal crisis has created pressure for institutional harmonization, but skeptics argue that cultural predispositions can prevent convergence in behavior. Our paper derives a robust cultural classification of European countries and utilizes unique data on natives and immigrants to Sweden. Classification based on genetic distance or on Hofstede’s cultural dimensions fails to identify a single ‘southern’ culture but points to a ‘northern’ culture. Significant differences in financial behavior are found across cultural groups, controlling for household characteristics. Financial behavior tends to converge with longer exposure to common institutions, but is slowed down by longer exposure to original institutions.
This is a chapter for a forthcoming volume Oxford Handbook of Financial Regulation (Oxford University Press 2014) (eds. Eilís Ferran, Niamh Moloney, and Jennifer Payne). It provides an overview of EU financial regulation from the first banking directive up until its most recent developments in the aftermath of the financial crisis, focusing on the multiple layers of multi-level governance and their characteristic conceptual difficulties. Therefore the paper discusses the need to accommodate cross-border capital flows following from the EU internal market and the resulting regulatory strategies. This includes a brief overview of the principle of home country control and the ensuing Financial Services Action Plan. Dealing with the accommodation of cross-border capital flows and their regulation necessarily require an orchestration of the underlying supervisory structures, which is therefore also discussed. In the aftermath of the financial crisis of 2007-09 an additional aspect of necessary orchestration has emerged, that is the need to control systemic risk. Specific attention is paid to microprudential supervision by the newly established European Supervisory Authorities and macroprudential supervision in the European Banking Union, the latter’s underlying drivers and the accompanying Single Supervisory Mechanism, including the SSM’s institutional framework as well as the consideration of its rationales and the Single Resolution Mechanism closely linked to it.
Die Struktur der makroprudenziellen Politik in der Europäischen Union ist ausgesprochen komplex und für den außenstehenden Betrachter fast undurchdringlich geworden. Deshalb wurde mit den Titeln der drei Kapitel des vorliegenden Aufsatzes „Der Prozess“, „Das Schloss“ und „Das Urteil“ bewusst auf Werke von Franz Kafka angespielt. Während sich der erste Teil der Arbeit vor allem mit der Komplexität des funktionellen Transmissionsprozesses in der makroprudenziellen Politik beschäftigt, widmet sich das zweite Kapitel, also der „Schloss-Teil“, ihren institutionellen Verflechtungen. Und am Ende werden die Ausführungen in einem „Wert-Urteil“ zusammengefasst.
On January 29, 2014, EU Commissioner Barnier published a draft law proposing a ban for proprietary trading by big banks in Europe. In this opinion piece, published in a German newspaper on 30 January, 2014, Jan Pieter Krahnen, who was a member of the Liikanen Commission, argues that the proposal could prove to be effective in preventing systemic risk.
Ein Freibrief für die Notenbank bedeutet, genau genommen, die Bankrotterklärung des demokratischen Verfassungsstaates vor technokratischen Beliebigkeiten, schreibt Helmut Siekmann in diesem Namensbeitrag. Er betont, dass die Europäische Union eine unverzichtbare Einrichtung ist und ein echter Bundesstaat sein sollte. Sie sei aber im Wesentlichen (nur) ein Rechtskonstrukt, weshalb es umso wichtiger sei, dass die rechtlichen Regeln, auf denen sie beruht, genauestens beachtet werden.
In the wake of the Global Financial Crisis that started in 2007, policymakers were forced to respond quickly and forcefully to a recession caused not by short-term factors, but rather by an over-accumulation of debt by sovereigns, banks, and households: a so-called “balance sheet recession.” Though the nature of the crisis was understood relatively early on, policy prescriptions for how to deal with its consequences have continued to diverge. This paper gives a short overview of the prescriptions, the remaining challenges and key lessons for monetary policy.
n a contribution prepared for the Athens Symposium on “Banking Union, Monetary Policy and Economic Growth”, Otmar Issing describes forward guidance by central banks as the culmination of the idea of guiding expectations by pure communication. In practice, he argues, forward guidance has proved a misguided idea. What is presented as state of the art monetary policy is an example of pretence of knowledge. Forward guidance tries to give the impression of a kind of rule-based monetary policy. De facto, however, it is an overambitious discretionary approach which, to be successful, would need much more (or rather better) information than is currently available. In Issing's view, communication must be clear and honest about the limits of monetary policy in a world of uncertainty.
Die „Rente mit 63“ hat wieder einmal den Blick auf den Renteneintritt gerichtet. In der öffentlichen Debatte werden dabei zwei Ereignisse regelmäßig vermischt: das Ende des Arbeitslebens und der Beginn der Rentenzahlung. Dabei müssen beide nicht unmittelbar aufeinander folgen. Unter bestimmten Umständen kann es finanziell attraktiv sein, die staatliche Rente nicht sofort nach dem Ausstieg aus dem Erwerbsleben zu beantragen, sondern die Ausgaben bis zum späteren Rentenbeginn durch den Abbau von Finanzkapital zu finanzieren. Dieser Beitrag gibt einen kurzen Einblick in die neueste Studie von Olivia Mitchell, Andreas Hubener und Raimund Maurer zur Alterssicherung in den USA und stellt auch Berechnungen für Deutschland auf.
We investigate the relationship between anchoring and the emergence of bubbles in experimental asset markets. We show that setting a visual anchor at the fundamental value (FV) in the first period only is sufficient to eliminate or to significantly reduce bubbles in laboratory asset markets. If no FV-anchor is set, bubble-crash patterns emerge. Our results indicate that bubbles in laboratory environments are primarily sparked in the first period. If prices are initiated around the FV, they stay close to the FV over the entire trading horizon. Our insights can be related to initial public offerings and the interaction between prices set on pre-opening markets and subsequent intra-day price dynamics.
he observed hump-shaped life-cycle pattern in individuals' consumption cannot be explained by the classical consumption-savings model. We explicitly solve a model with utility of both consumption and leisure and with educational decisions affecting future wages. We show optimal consumption is hump shaped and determine the peak age. The hump results from consumption and leisure being substitutes and from the implicit price of leisure being decreasing over time; more leisure means less education, which lowers future wages, and the present value of foregone wages decreases with age. Consumption is hump shaped whether the wage is hump shaped or increasing over life.
This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ranging from low to high. Attitudes towards risk and attitudes towards ambiguity are disentangled, providing pure measures of ambiguity aversion. Ambiguity aversion is captured in several ways, i.e. as a discount factor net of a risk premium, and as an estimated parameter in a generalized utility function. We find that ambiguity aversion varies across individuals, and with the level of ambiguity, being most prominent for intermediate levels. Around one third of subjects show no aversion, one third show maximum aversion, and one third show intermediate levels of ambiguity aversion, while there is almost no ambiguity seeking. While most theoretical work on ambiguity builds on maxmin expected utility, our results provide evidence that MEU does not adequately capture individual attitudes towards ambiguity for the majority of individuals. Instead, our results support models that allow for intermediate levels of ambiguity aversion. Moreover, we find risk aversion to be statistically unrelated to ambiguity aversion on average. Taken together, the results support the view that ambiguity is an important and distinct argument in decision making under uncertainty.
SAFE Newsletter : 2014, Q2
(2014)
We study consumption-portfolio and asset pricing frameworks with recursive preferences and unspanned risk. We show that in both cases, portfolio choice and asset pricing, the value function of the investor/representative agent can be characterized by a specific semilinear partial differential equation. To date, the solution to this equation has mostly been approximated by Campbell-Shiller techniques, without addressing general issues of existence and uniqueness. We develop a novel approach that rigorously constructs the solution by a fixed point argument. We prove that under regularity conditions a solution exists and establish a fast and accurate numerical method to solve consumption-portfolio and asset pricing problems with recursive preferences and unspanned risk. Our setting is not restricted to affine asset price dynamics. Numerical examples illustrate our approach.
We study self- and cross-excitation of shocks in the Eurozone sovereign CDS market. We adopt a multivariate setting with credit default intensities driven by mutually exciting jump processes, to capture the salient features observed in the data, in particular, the clustering of high default probabilities both in time (over days) and in space (across countries). The feedback between jump events and the intensity of these jumps is the key element of the model. We derive closed-form formulae for CDS prices, and estimate the model by matching theoretical prices to their empirical counterparts. We find evidence of self-excitation and asymmetric cross-excitation. Using impulse-response analysis, we assess the impact of shocks and a potential policy intervention not just on a single country under scrutiny but also, through the effect on cross-excitation risk which generates systemic sovereign risk, on other interconnected countries.
Exit strategies
(2014)
We study alternative scenarios for exiting the post-crisis fiscal and monetary accommodation using a macromodel where banks choose their capital structure and are subject to runs. Under a Taylor rule, the post-crisis interest rate hits the zero lower bound (ZLB) and remains there for several years. In that condition, pre-announced and fast fiscal consolidations dominate - based on output and inflation performance and bank stability - alternative strategies incorporating various degrees of gradualism and surprise. We also examine an alternative monetary strategy in which the interest rate does not reach the ZLB; the benefits from fiscal consolidation persist, but are more nuanced.
We study the behavioral underpinnings of adopting cash versus electronic payments in retail transactions. A novel theoretical and experimental framework is developed to primarily assess the impact of sellers’ service fees and buyers’ rewards from using electronic payments. Buyers and sellers face a coordination problem, independently choosing a payment method before trading. In the experiment, sellers readily adopt electronic payments but buyers do not. Eliminating service fees or introducing rewards significantly boosts the adoption of electronic payments. Hence, buyers’ incentives play a pivotal role in the diffusion of electronic payments but monetary incentives cannot fully explain their adoption choices. Findings from this experiment complement empirical findings based on surveys and field data.
Securities transaction tax in France: impact on market quality and inter-market price coordination
(2014)
The general concept of a Securities Transaction Tax is controversial among academics and politicians. While theoretical research is quite advanced, the empirical guidance in a fragmented market context is still scarce. Possible negative effects for market liquidity and market efficiency are theoretically predicted, but have not been empirically tested yet. In light of the agreement of eleven European member states to implement an STT, this study aims to give a comprehensive overview of the effects of the STT, introduced in France in 2012, on liquidity demand, liquidity supply, volatility and inter-market information transmission. The results show that the STT has led to a decline in liquidity demand, has had a detrimental effect on liquidity supply and negatively influences the inter-market information transmission efficiency. However, no effect on volatility can be observed.
Die Stellungnahme befasst sich mit einem wichtigen Aspekt der Offenlegung der Bezüge von Entscheidungsträgern im Bankensektor. Komplementär zu der Diskussion um die Veröffentlichung der Vergütung von Vorstandsmitgliedern börsennotierter Unternehmen ist auch auf Landeseben versucht worden, die Transparenz der Vergütung von Führungskräften kommunaler oder landeseigener Unternehmen zu erhöhen. Namentlich sind die Träger der Sparkassen durch den neuen § 19 Abs. 6 des Sparkassengesetzes von Nordrhein-Westfalen verpflichtet worden, darauf „hinzuwirken“, dass die „gewährten Bezüge jedes einzelnen Mitglieds des Vorstands, des Verwaltungsrates und ähnlicher Gremien unter Namensnennung“ veröffentlich werden. Diese Vorschrift ist jedoch weitgehend wirkungslos geblieben; nicht zuletzt weil das OLG Köln in einer einstweiligen Verfügung die Vorschrift mangels Gesetzgebungskompetenz des Landes als nichtig behandelt hat. In dieser Situation ist am 8. August 2013 der Vorschlag eines Gesetzes „zur Offenlegung der Bezüge von Sparkassenführungskräften im Internet“ durch die Fraktion der Piraten im Landtag Nordrhein-Westfalen eingebracht worden. Der Entwurf ist Gegenstand der Stellungnahme, die Helmut Siekmann für den Haushalts- und Finanzausschuss des Landtags Nordrhein-Westfalen erstellt hat. Sie stellt maßgebend darauf ab, dass die Sparkassen als Anstalten des öffentlichen Rechts einen öffentlichen Auftrag zu erfüllen haben und den Grundsätzen des Verwaltungsorganisationsrechts unterliegen. Als Teil der (leistenden) Verwaltung müssen sie Transparenz- und Kontrollansprüchen der Bürger und ihren Repräsentanten in den Parlamenten genügen.
In the United States, on April 1, 2014, the set of rules commonly known as the "Volcker Rule", prohibiting proprietary trading activities in banks, became effective. The implementation of this rule took more than three years, as “proprietary trading” is an inherently vague concept, overlapping strongly with genuinely economically useful activities such as market-making. As a result, the final Rule is a complex and lengthy combination of prohibitions and exemptions.
In January 2014, the European Commission put forward its proposal on banking structural reform. The proposal includes a Volcker-like provision, prohibiting large, systemically relevant financial institutions from engaging in proprietary trading or hedge fund-related business. This paper offers lessons to be learned from the implementation process for the Volcker rule in the US for the European regulatory process.
Der vorliegende Artikel analysiert systematisch die Erreichung der MiFID-Ziele anhand der wissenschaftlichen Literatur. Ziel der MiFID ist es, die Rahmenbedingungen für einen effizienten und kostengünstigen Wertpapierhandel zu schaffen. Erreicht werden soll dies durch die Verschärfung des Wettbewerbs, die Integration der Märkte, die Offenlegung von Handelsintentionen und -geschäften sowie die Stärkung der rechtlichen Position der Investoren. Im Ergebnis zeigt sich, dass die Förderung des Wettbewerbes als erfolgreich bewertet wird, aber die regulatorischen Möglichkeiten der Marktintegration nicht ausgeschöpft werden. Ferner wird die Forderung nach einheitlichen Transparenzbestimmungen für alle Ordermechanismen nur teilweise umgesetzt. Der Anleger erfährt letztlich gegenüber Finanzintermediären durch die MiFID keinen höheren Schutz.
Financial innovation is, as usual, faster than regulation. New forms of speculation and intermediation are rapidly emerging. Largely as a result of the evaporation of trust in financial intermediation, an exponentially increasing role is being played by the so-called peer to peer intermediation. The most prominent example at the moment is Bitcoin.
If one expects that shocks in these markets could destabilize also traditional financial markets, then it will be necessary to extend regulatory measures also to these innovations.
Fünf Jahre nach Beginn der Banken- und Staatsschuldenkrise („Finanzkrise“) kämpfen wir weiterhin mit den elementaren Problemen: Bei Märkten und Marktteilnehmern fehlt es an Stabilität und Vertrauen. Viele Banken stehen immer noch nicht auf eigenen Füßen und nehmen die ihnen in Europa traditionell zukommende zentrale Rolle für Wachstum und Entwicklung nicht wahr. Den guten Absichten, auf die sich die großen politischen Mächte während der ersten G-20 Treffen 2008 und 2009 verständigt hatten, ist eine Reihe von sinnvollen Ideen und Konzepten gefolgt. Die Voraussetzungen für einen grundlegenden reformerischen Erfolg sind somit gegeben – doch nun muss die Umsetzung folgen. Dazu bedarf es mutiger Entscheidungen. Im Jahr 2014 muss die europäische Politik gleich mehrere Weichen stellen. Der Bundesregierung kommt dabei die Schlüsselrolle zu. Sie muss den Mut haben zu radikaler Ordnungspolitik!
This article discusses the recent proposal for debt restructuring in the euro zone by Pierre Paris and Charles Wyplosz. It argues that the plan cannot realize the promised debt relief without producing moral hazard. Ester Faia revisits the Redemption Fund proposed in November 2011 by the German Council of Economic Experts and argues that this plan, up to date, still remains the most promising path towards succesful debt restructuring in Europe.
Das ursprüngliche Ziel des Erneuerbare-Energien-Gesetz war die Verringerung der Emissionen. Eigentlich hat die Politik bereits ein Instrument an der Hand, das dieses Ziel fokussiert und kostensparend erreichen kann: den Handel mit CO2-Zertifikaten. Der Autor argumentiert, dass das Nebeneinander von CO2-Handel und EEG höchst unproduktiv ist und schleunigst beendet werden sollte. Ein plausibleres Argument für den politischen Erfolg des EEG und das derzeitige Herumdoktern im Detail ist, dass die Politik mit dem EEG Industriepolitik betreiben und die Kosten auf zukünftige Parlamente und Generationen überwälzen kann.
On November 8, 2013, several members of the British House of Lords’ Subcommittee A conducted a hearing at the ECB in Frankfurt, Germany, on “Genuine Economic and Monetary Union and its Implications for the UK”. Professors Otmar Issing and Jan Pieter Krahnen were called as expert witnesses.
The testimony began with a general discussion on the elements considered necessary for a functioning internal market. Do economic union and monetary union require a fiscal union or even a political union, beyond the elements of the banking union currently being prepared? In this context, also the critique of the German current account surplus and the international expectations that Germany stimulate internal demand to support growth in crisis countries, were discussed.
With regard to the monetary union, the members of the subcommittee asked for an assessment of how European nations and the banking industry would have fared in the banking crisis that followed the Lehman collapse, had there not been a common currency. Given the important role that the ECB has played in the course of the crisis management, the members further asked for an evaluation of the OMT-program of the ECB and also if the monetary union is in need of common debt instruments, in order to provide the ECB with the possibility of buying EU liabilities, comparable to the Fed buying US Treasury bonds. Finally, the dual role of the ECB for monetary policy and banking supervision was an issue touched on by several questions.
In many cases, the dire situation of public finances calls into question the very soundness of sovereigns and prompts corrective actions with far-reaching consequences. In this context, European authorities responded with several measures on different fronts, for instance by passing the "Fiscal Compact", which entered into force on January 1, 2013. Of critical importance in this framework is the assessment of a country’s situation by way of statistical measures, in order to take corrective actions when called for according to the letter of the law. If these statistics are not correct, there is a risk of imposing draconian measures on countries that do not really need it.
Before the 2007–09 crisis, standard risk measurement methods substantially underestimated the threat to the financial system. One reason was that these methods didn’t account for how closely commercial banks, investment banks, hedge funds, and insurance companies were linked. As financial conditions worsened in one type of institution, the effects spread to others. A new method that more accurately accounts for these spillover effects suggests that hedge funds may have been central in generating systemic risk during the crisis.
Social impact bonds are a special type of bond whose purpose is to provide long term funds to projects with a social impact. Especially in the UK and in the US these bonds are increasingly being used to raise funds to finance government projects. Their return depends on the social improvements achieved. Especially in times of crisis, governments lack funds to prevent the social consequences of recessions. Faia argues that the European Union should develop an equivalent to the British Social Finance Ltd. to finance projects for social improvement.
Neither Northerners are willing to invest in a South they perceive as unwilling to undertake necessary structural reforms, nor are Southerners willing to invest in their countries in a climate of austerity and policy uncertainty imposed, in their view, by the North. This results in a vicious cycle of mistrust. However, as the author argues, big steps in the direction of reforms may provide just enough thrust to break out of this vicious cycle, propel southern countries – and especially Greece – to a much happier future, and promote the chances for more balanced economic performance in North and South.
Social Security rules that determine retirement, spousal, and survivor benefits, along with benefit adjustments according to the age at which these are claimed, open up a complex set of financial options for household decisions. These rules influence optimal household asset allocation, insurance, and work decisions, subject to life cycle demographic shocks, such as marriage, divorce, and children. Our model-based research generates a wealth profile and a low and stable equity fraction consistent with empirical evidence. We confirm predictions that wives will claim retirement benefits earlier than husbands, while life insurance is mainly purchased by younger men. Our policy simulations imply that eliminating survivor benefits would sharply reduce claiming differences by sex while dramatically increasing men’s life insurance purchases.
One of the motivations for establishing a European banking union was the desire to break the ties with between national regulators and domestic financial institutions in order to prevent regulatory capture. However, supervisory authority over the financial sector at the national level can also have valuable public benefits. The aim of this policy letter is to detail these public benefits in order to counter discussions that focus only on conflicts of interest. It is informed by an analysis of how financial institutions interacted with policy-makers in the design of national bank rescue schemes in response to the banking crisis of 2008. Using this information, it discusses the possible benefits of close cooperation between financial institutions and regulators and analyzes these in the wake of a European banking union.
This paper makes a conceptual contribution to the effect of monetary policy on financial stability. We develop a microfounded network model with endogenous network formation to analyze the impact of central banks' monetary policy interventions on systemic risk. Banks choose their portfolio, including their borrowing and lending decisions on the interbank market, to maximize profit subject to regulatory constraints in an asset-liability framework. Systemic risk arises in the form of multiple bank defaults driven by common shock exposure on asset markets, direct contagion via the interbank market, and firesale spirals. The central bank injects or withdraws liquidity on the interbank markets to achieve its desired interest rate target. A tension arises between the beneficial effects of stabilized interest rates and increased loan volume and the detrimental effects of higher risk taking incentives. We find that central bank supply of liquidity quite generally increases systemic risk.
This paper explores consequences of consumer education on prices and welfare in retail financial markets when some consumers are naive about shrouded add-on prices and firms try to exploit it. Allowing for different information and pricing strategies we show that education is unlikely to push firms to disclose prices towards all consumers, which would be socially efficient. Instead, price discrimination emerges as a new equilibrium. Further, due to a feedback on prices, education that is good for consumers who become sophisticated may be bad for consumers who stay naive and even for the group of all consumers as a whole

Banks can deal with their liquidity risk by holding liquid assets (self-insurance), by participating in interbank markets (coinsurance), or by using flexible financing instruments, such as bank capital (risk-sharing). We use a simple model to show that undiversifiable liquidity risk, i.e. the liquidity risk that banks are unable to coinsure on interbank markets, represents an important risk factor affecting their capital structures. Banks facing higher undiversifiable liquidity risk hold more capital. We posit that empirically banks that are more exposed to undiversifiable liquidity risk are less active on interbank markets. Therefore, we test for the existence of a negative relationship between bank capital and interbank market activity and find support in a large sample of U.S. commercial banks.
I analyze a critical illness insurance in a consumption-investment model over the life cycle. I solve a model with stochastic mortality risk and health shock risk numerically. These shocks are interpreted as critical illness and can negatively affect the expected remaining lifetime, the health expenses, and the income. In order to hedge the health expense effect of a shock, the agent has the possibility to contract a critical illness insurance. My results highlight that the critical illness insurance is strongly desired by the agents. With an insurance profit of 20%, nearly all agents contract the insurance in the working stage of the life cycle and more than 50% of the agents contract the insurance during retirement. With an insurance profit of 200%, still nearly all working agents contract the insurance, whereas there is little demand in the retirement stage.
I numerically solve realistically calibrated life cycle consumption-investment problems in continuous time featuring stochastic mortality risk driven by jumps, unspanned labor income as well as short-sale and liquidity constraints and a simple insurance. I compare models with deterministic and stochastic hazard rate of death to a model without mortality risk. Mortality risk has only minor effects on the optimal controls early in the life cycle but it becomes crucial in later years. A diffusive component in the hazard rate of death has no significant impact, whereas a jump component is desired by the agent and influences optimal controls and wealth evolution. The insurance is used to ensure optimal bequest such that there is no accidental bequest. In the absence of the insurance, the biggest part of bequest is accidental.
We explore the sources of household balance sheet adjustment following the collapse of the housing market in 2006. First, we use microdata from the Federal Reserve Board’s Senior Loan Officer Opinion Survey to document that banks cumulatively tightened consumer lending standards more in counties that experienced a house price boom in the mid-2000s than in non-boom counties. We then use the idea that renters, unlike homeowners, did not experience an adverse wealth shock when the housing market collapsed to examine the relative importance of two explanations for the observed deleveraging and the sluggish pickup in consumption after 2008. First, households may have optimally adjusted to lower wealth by reducing their demand for debt and implicitly, their demand for consumption. Alternatively, banks may have been more reluctant to lend in areas with pronounced real estate declines. Our evidence is consistent with the second explanation. Renters with low risk scores, compared to homeowners in the same markets, reduced their levels of nonmortgage debt and credit card debt more in counties where house prices fell more. The contrast suggests that the observed reductions in aggregate borrowing were more driven by cutbacks in the provision of credit than by a demand-based response to lower housing wealth.

In this paper, we study the effect of proportional transaction costs on consumption-portfolio decisions and asset prices in a dynamic general equilibrium economy with a financial market that has a single-period bond and two risky stocks, one of which incurs the transaction cost. Our model has multiple investors with stochastic labor income, heterogeneous beliefs, and heterogeneous Epstein-Zin-Weil utility functions. The transaction cost gives rise to endogenous variations in liquidity. We show how equilibrium in this incomplete-markets economy can be characterized and solved for in a recursive fashion. We have three main findings. One, costs for trading a stock lead to a substantial reduction in the trading volume of that stock, but have only a small effect on the trading volume of the other stock and the bond. Two, even in the presence of stochastic labor income and heterogeneous beliefs, transaction costs have only a small effect on the consumption decisions of investors, and hence, on equity risk premia and the liquidity premium. Three, the effects of transaction costs on quantities such as the liquidity premium are overestimated in partial equilibrium relative to general equilibrium.
Even though fiscal sovereignty still counts as a fundamental principle of government, global and regional economic integration as well as increasing levels of sovereign debt severely limit governments’ tax policy choices. In particular the redistributive function of taxation has suffered in the pursuit of economic competitiveness. As inequality rises and attention is directed again at taxation as a means for redistribution, international cooperation appears as an avenue to enable redistribution through taxation. Yet, one of the predominant international institutions dealing with tax matters – the OECD – with its focus on economic growth and competitiveness and resulting tax policy advice prevents rather than promotes national and international debates on taxation as a question of social justice. The paper argues that questions of taxation need to be perceived as questions of social justice and thus as questions of politics, and not merely of economics. Only if taxation is not considered a mere economic instrument can a ‘political economy’ be maintained. The paper addresses the three objectives of taxation – revenue generation, redistribution and regulation -- and how they are affected as governments aim for fiscal consolidation to conclude that governments’ power to freely pursue and calibrate these objectives has come to appear rather as a myth than the core of sovereignty. It then demonstrates how the OECD’s tax policy advice and cooperation in tax matters react to the constraints on governmental taxation powers; how they aim at economic growth and competitiveness to the detriment of (other) ideas of social justice. The paper concludes with a call for (re)integrating social and global justice concerns into debates on taxation.
Das Paper geht der Frage nach, welche Rolle Verteilungsgerechtigkeit in Völkerrecht und Völkerrechtswissenschaft spielt. Es stellt zunächst zwei Völkerrechtsprojekte der Nachkriegszeit dar, in deren Zentrum Verteilungsfragen standen: erstens den „embedded liberalism“ Kompromiss von Bretton Woods und zweitens die von den Entwicklungsländern in den 1970er Jahren geforderte Neue Weltwirtschaftsordnung. Nach kurzer Darstellung des Scheiterns von „embedded liberalism“ und Neuer Weltwirtschaftsordnung und der Gründe für ihren Misserfolg, wendet sich das paper der Völkerrechtswissenschaft zu. Zwei zeitgenössische Projekte der Völkerrechtswissenschaft – Konstitutionalisierung des Völkerrechts und Konzeptualisierung des Völkerrechts als öffentliches Recht – werden danach befragt, welche Antworten sie auf die Krise von „welfare state and welfare world“ geben. Während sich der völkerrechtliche Konstitutionalismus nur unzureichend mit dem Verhältnis von Wirtschaft und Politik befasst, verliert die Konzeptualisierung des Völkerrechts als öffentliches Recht mit ihrem Fokus auf das Völkerrecht als Instrument der Beschränkung öffentlicher Gewalt zur Sicherung individueller Freiheit viele Verteilungsfragen gänzlich aus dem Blick. Um das Potential von Recht zur Herstellung von Verteilungsgerechtigkeit auszuloten, scheint daher eine Ausweitung der Perspektive auf transnationales Recht von Nöten. Ausgehend von Gunther Teubners gesellschaftlichem Konstitutionalismus skizziert das Paper Versuche der (transnationalen) Rechtswissenschaft, Fragen ungerechter bzw. gerechter Verteilung zu thematisieren. Das Paper schließt mit der Aufforderung, dass sich eine an Verteilungsgerechtigkeit orientierte transnationale Rechtswissenschaft folgenden Aufgaben widmen sollte: erstens der Bestimmung von Verteilungskonflikten mit Hilfe politischer Ökonomie und rechtspluralistischen Ansätzen und zweitens der Identifikation von Institutionen für einen demokratischen Experimentalismus.
Dieser Beitrag stellt das transnationale Rohstoffrecht und seine Entwicklung aus einer Konfliktperspektive dar und setzt es in Beziehung zu geopolitischen Transformationen und Wandlungen des Entwicklungsbegriffs. Sachlicher Gegenstand dieses Unterfangens sind erschöpfliche Vorkommen von Rohstoffen in Entwicklungsländern, ihre Ausbeutung und der Handel mit den gewonnenen Rohstoffen. Der Fokus liegt auf Mineralien, Öl und Gas. Der Text ist ein Versuch, Verantwortlichkeiten verschiedener Akteure für anhaltende Armut trotz Rohstoffreichtums greifbarer zu machen.
In this paper, we propose a novel approach on how to estimate systemic risk and identify its key determinants. For all US financial companies with publicly traded equity options, we extract their option-implied value-at-risks (VaRs) and measure the spillover effects between individual company VaRs and the option-implied VaR of an US financial index. First, we study the spillover effect of increasing company risks on the financial sector. Second, we analyze which companies are most affected if the tail risk of the financial sector increases. We find that key accounting and market valuation metrics such as size, leverage, balance sheet composition, market-to-book ratio and earnings have a significant influence on the systemic risk profile of a financial institution. In contrast to earlier studies, the employed panel vector autoregression (PVAR) estimator allows for a causal interpretation of the results.
