An important assumption underlying the designation of some insurers as systemically important is that their overlapping portfolio holdings can result in common selling. We measure the overlap in holdings using cosine similarity, and show that insurers with more similar portfolios have larger subsequent common sales. This relationship can be magnified for some insurers when they are regulatory capital constrained or markets are under stress. When faced with an exogenous liquidity shock, insurers with greater portfolio similarity have even larger common sales that impact prices. Our measure can be used by regulators to predict which institutions may contribute most to financial instability through the asset liquidation channel of risk transmission.
This paper investigates inertia within and across banks in retail deposit markets using detailed panel data on consumer choices and account characteristics. In a structural choice model, I find that costs of inertia are around one third higher for switching accounts across compared to switching within banks. Observable proxies of bank-level switching costs (number and type of additional financial products) explain most of this cost premium, while online banking usage reduces inertia. Consistent with theory, I provide evidence that banks incorporate inertia in their pricing as older accounts pay lower rates than comparable newer accounts. Counterfactual policies reducing inertia shift market share to more competitive smaller banks, but only eliminating inertia within banks already results in high potential gains in consumer surplus. This suggests that facilitating bank switching alone might be insufficient to improve consumer choices.
In recent years European financial regulation has experienced a tremendous reorientation with respect to the shadow banking system, which manifested first and foremost in its reframing as market-based finance. Initially identified as a source of systemic risk certain initiatives did not only fall much behind the envisaged changes but all to the contrary have been substantially modified in a way that they now aim at revitalizing these activities. The reorientation of European regulatory agency on shadow banking post-crisis, from curtailing it to facilitating resilient market-based finance, has been a cause for irritation by academic observers, dismissed by some as mere rebranding or taken as a sign of regulatory capture. All to the contrary, this paper documents the central role of regulatory agency in shadow banking’s reconfiguration. It does so by analyzing the European initiatives concerning the regulation of Asset-Backed Commercial Paper (ABCP) and another prime example of shadow banking, Money Market Mutual Funds (MMFs). Based on documentary analysis and expert interviews we trace the way the recently published EU frameworks for MMFs and ABCP have been designed (in particular the STS, CRR and MMF regulation in 2017). Furthermore, we show how they have been transformed in such a way that their final versions allow to re-establish the shadow banking chain linking MMFs, the ABCP market and arguably the regular banking system. This transformation is driven by a new form of pro-active European regulatory agency which aims at creating a regulatory infrastructure able to sustain the orderly flow of real economy debt. Far from being captured by the industry, they did so consciously and in cooperation with private actors in order to maintain a channel for credit creation outside of bank credit, a task made more complicated by the rushed politicized final negotiations coupled with technical complexity. This paper thereby contributes to a new strand of literature, seeing the creation and reconfiguration of the shadow banking system as characterized by the active and conscious role of state actors.
We propose a unified framework to measure the effects of different reforms of the pension system on retirement ages and macroeconomic indicators in the face of demographic change. A rich overlapping generations (OLG) model is built and endogenous retirement decisions are explicitly modeled within a public pension system. Heterogeneity with respect to consumption preferences, wage profiles, and survival rates is embedded in the model. Besides the expected direct effects of these reforms on the behavior of households, we observe that feedback effects do occur. Results suggest that individual retirement decisions are strongly influenced by numerous incentives produced by the pension system and macroeconomic variables, such as the statutory eligibility age, adjustment rates, the presence of a replacement rate, and interest rates. Those decisions, in turn, have several impacts on the macro-economy which can create feedback cycles working through equilibrium effects on interest rates and wages. Taken together, these reform scenarios have strong implications for the sustainability of pension systems. Because of the rich nature of our unified model framework, we are able to rank the reform proposals according to several individual and macroeconomic measures, thereby providing important support for policy recommendations on pension systems.
The paper investigates the determinants of the idiosyncratic volatility puzzle by allowing linkages across asset returns. The first contribution of the paper is to show that portfolios sorted by increasing indegree computed on the network based on Granger causality test have lower expected returns, not related to idiosyncratic volatility. Secondly, empirical evidence indicates that stocks with higher idiosyncratic volatility have the lower exposition on the indegree risk factor.
We examine how a firms' investment behavior affects the investment of a neighboring firm. Economic theory yields ambiguous predictions regarding the direction of firm peer effects and consistent with earlier work, we find that firms display similar investment behavior within an area using OLS analysis. Exploiting time-variation in the rise of U.S. states' corporate income taxes and utilizing heterogeneity in firms' exposure to increases in corporate income tax rates, we identify the causal impact of local firms' investments. Using this as an instrumental variable in a 2SLS estimation, we find that an increases in local firms' investment reduces the investment of a local peer firm. This effect is more pronounced if local competition among firms is stronger and supports theories that firm investments are strategic substitutes due to competition.
We use minutes from 17,000 financial advisory sessions and corresponding client portfolio data to study how active client involvement affects advisor recommendations and portfolio outcomes. We find that advisors confronted with acquiescent clients stick to their standards and recommend expensive but well diversified mutual fund portfolios. However, if clients take an active role in the meetings, advisors deviate markedly from their standards, resulting in poorer portfolio diversification and lower Sharpe ratios. Our findings that advisors cater to client requests parallel the phenomenon of doctors prescribing antibiotics to insistent patients even if inappropriate, and imply that pandering diminishes the quality of advice.
This paper provides a complete characterization of optimal contracts in principal-agent settings where the agent's action has persistent effects. We model general information environments via the stochastic process of the likelihood-ratio. The martingale property of this performance metric captures the information benefit of deferral. Costs of deferral may result from both the agent's relative impatience as well as her consumption smoothing needs. If the relatively impatient agent is risk neutral, optimal contracts take a simple form in that they only reward maximal performance for at most two payout dates. If the agent is additionally risk-averse, optimal contracts stipulate rewards for a larger selection of dates and performance states: The performance hurdle to obtain the same level of compensation is increasing over time whereas the pay-performance sensitivity is declining.
Im Jahr 1564 veröffentlicht der Ulmer Militärexperte und -schriftsteller Leonhard Fronsperger die Schrift "Von dem Lob deß Eigen Nutzen", in der er darlegt, dass die konsequente Verfolgung des eigenen Nutzens als individuelle Handlungsmaxime im Ergebnis zu einer Förderung des Gemeinwohls führt. Das etwas mehr als hundert Seiten umfassende Werk wird in Frankfurt am Main, einem Zentrum des europäischen Buchdrucks und -handels, verlegt und findet Erwähnung im ersten veröffentlichten Katalog der Frankfurter Buchmesse. Fronsperger präsentiert seine für die damalige Zeit durchaus revolutionäre These in der Form eines satirischen Enkomions und unterlegt sie mit einer umfangreichen Gesellschaftsanalyse. Er stellt fest, dass die politischen Herrschaftsformen, die gesellschaftlichen Institutionen und die wirtschaftlichen Handelsbeziehungen auf einer konsequenten Verfolgung des eigenen Nutzens aller Akteure beruhen und dass sich die von der Kirche geforderte Ausrichtung des individuellen Handelns am Gemeinwohl in der Realität nicht finden lässt. Vielmehr hält er die Kritik der Theologen am egoistischen Handeln des Einzelnen für falsch, empfindet er doch den Staat, Wirtschaft und Gesellschaft im Großen und Ganzen als gut funktionierend.
Im Folgenden dokumentieren wir zunächst die Biografie des Autors, die Entstehung und Verbreitung des Werks und seine besondere literarische Form. Anschließend diskutieren wir die zentrale These in drei verschiedenen geistesgeschichtlichen Kontexten, die jeweils von besonderer Bedeutung für die Herausbildung der neuzeitlichen Gesellschafts- und Wirtschaftstheorien sind. Erkenntnis- und staatstheoretisch weist Fronspergers Werk deutliche Parallelen zu den Analysen auf, die Niccolò Machiavelli und später Giovanni Botero in Italien zur Bedeutung der auf den individuellen fürstlichen Interessen basierenden Staatsräson bzw. zu den Triebkräften erfolgreicher Stadtentwicklung vorlegten. Markante Unterschiede gibt es dagegen zu den Ansichten der deutschsprachigen Reformatoren im Anschluss an Luther, die zwar die Unterscheidung zwischen geistlicher und weltlicher Sphäre propagieren und damit die Entwicklung einer eigenständigen Moral für das Wirtschaftsleben befördern, dort allerdings mehrheitlich die Orientierung am "Gemeinen Nutzen" propagieren. Indem Fronsperger dagegen die Verfolgung des Eigennutzes fordert, nimmt er wirtschafts- und gesellschaftstheoretische Einsichten über das Wesen und die Auswirkungen der Arbeitsteilung vorweg, die erst 150 Jahre und später von Bernard Mandeville und Adam Smith in England und Schottland formuliert wurden. Das Werk Fronspergers bietet damit ein herausragendes Beispiel dafür, wie sich aus dem Zusammenspiel von wirtschaftlichem Erfolg, einem realistischen Menschenbild und manchen Aspekten der Reformation in deren Folge ein neues normatives Verständnis von den Antriebskräften ökonomischer und gesellschaftlicher Dynamik entwickelt, das später als der "Geist des Kapitalismus" bezeichnet wird.

This study explores anomalies in stock returns found in their seasonal patterns. These are verified through multiple trading strategies based on past-performance returns that require information up to 20 years in the past. Some of the presented strategies deliver relatively high performance, especially for those strategies based on returns in the same calendar month from past years. In order to minimize any possible bias due to omitted delisting returns, those are incorporated into the monthly returns. Furthermore, to find an explanation for this seasonal effect, behavioral theories are discussed and the returns are controlled for risk and mispricing factors. However, empirical evidence indicates no evidence of explanation based on these factors for the seasonal patterns. Furthermore, possible reasons why the returns persist are discussed.
A growing body of literature shows the importance of financial literacy in households' financial decisions. However, fewer studies focus on understanding the determinants of financial literacy. Our paper fills this gap by analyzing a specific determinant, the educational system, to explain the heterogeneity in financial literacy scores across Germany. We suggest that the lower financial literacy observed in East Germany is partially caused by a different institutional framework experienced during the Cold War, more specifically, by the socialist educational system of the GDR which affected specific cohorts of individuals. By exploiting the unique set-up of the German reunification, we identify education as a channel through which institutions and financial literacy are related in the German context.
How demanding and consistent is the 2018 stress test design in comparison to previous exercises?

Bank regulators have the discretion to discipline banks by executing enforcement actions to ensure that banks correct deficiencies regarding safe and sound banking principles. We highlight the trade-offs regarding the execution of enforcement actions for financial stability. Following this we provide an overview of the differences in the legal framework governing supervisors’ execution of enforcement actions in the Banking Union and the United States. After discussing work on the effect of enforcement action on bank behaviour and the real economy, we present data on the evolution of enforcement actions and monetary penalties by U.S. regulators. We conclude by noting the importance of supervisors to levy efficient monetary penalties and stressing that a division of competences among different regulators should not lead to a loss of efficiency regarding the execution of enforcement actions.
A new governance architecture for european financial markets? Towards a european supervision of CCPs
(2018)
Does the new European outlook on financial markets, as voiced by the EU Commission since the beginning of the Capital Market Unions imply a movement of the EU towards an alignment of market integration and direct supervision of common rules? This paper sets out to answer this question for the case of common supervision for Central Counterparties (CCPs) in the European Union. Those entities gained crucial importance post-crisis due to new regulation which requires the mandatory clearing of standardized derivative contracts, transforming clearing houses into central nodes for cross-border financial transactions. While the EU-wide regulatory framework EMIR, enacted in 2012, stipulates common regulatory requirements, the framework still relies on home-country supervision of those rules, arguably leading to regulatory as well as supervisory arbitrage. Therefore, the regulatory reform to stabilize the OTC derivatives market replicated at its center a governance flaw, which had been identified as one of the major causes for the gravity of the financial crisis in the EU: the coupling of intense competition based on private risk management systems with a national supervision of European rules. This paper traces the history of this problem awareness and inquires which factors account for the fact that only in 2017 serious negotiations at the EU level ensued that envisioned a common supervision of CCPs to fix the flawed system of governance. Analyzing this shift in the European governance architecture, we argue that Brexit has opened a window of opportunity for a centralization of supervision for CCPs. Brexit aligns the urgency of the problem with material interests of crucial political stakeholder, in particular of Germany and France, providing the possibility for a grand European bargain.
Improving financial conditions of individuals requires an understanding of the mechanisms through which bad financial decision-making leads to worse financial outcomes. From a theoretical point of view, a key candidate inducing mistakes in financial decision-making are so called present-biased preferences, which are one of the cornerstones of behavioral economics. According to theory, present-biased households should behave systematically different when it comes to consumption and saving decisions, as they should be more prone to spending too much and saving too little.
In this policy letter we show how high frequency financial transaction data available in digitized form allows to precisely categorize individual financial-decision making to be present-biased or not. Using this categorization, we find that one out of five individuals in our sample exhibits present-bias and that this present-biased behavior is associated with a stronger use of overdrafts. As overdrafts represent a particularly expensive way of short-term borrowing, their systematic use can be interpreted as a measure of suboptimal financial-decision making. Overall, our results indicate that the combination of economic theory and Big Data is able to generate valuable insights with applications for policy makers and businesses alike.
We develop a model that reproduces the average return and volatility spread between sin and non-sin stocks. Our investors do not necessarily boycott sin companies. Rather, they are open to invest in any company while trading off dividends against ethicalness. We show that when dividends and ethicalness are complementary goods and investors are sufficiently risk averse, the model predicts that the dividend share of sin companies exhibits a positive relation with the future return and volatility spreads. Our empirical analysis supports the model's predictions.
In the last decade, central bank interventions, flights to safety, and the shift in derivatives clearing resulted in exceptionally high demand for high quality liquid assets, such as German treasuries, in the securities lending market besides the traditional repo market activities. Despite the high demand, the realizable securities lending income has remained economically negligible for most beneficial owners. We provide empirical evidence of pricing inefficiencies in the non-transparent, oligopolistic securities lending market for German treasuries from 2006 to 2015. Consistent with Duffie, Gârleanu and Pedersen (2005)’s theory, we find that the less connected market participants’ interests are underrepresented, evident in the longer maturity segment, where lenders are more likely to be conservative passive investors, such as pension funds and insurance firms. The low price elasticity in this segment hinders these beneficial owners to fully capitalize on the additional income from securities lending, giving rise to important negative welfare implications.
In this study we investigate which economic ideas were prevalent in the macroprudential discourse post-crises in order to understand the availability of ideas for reform minded agents. We base our analysis on new findings in the field of ideational shifts and regulatory science, which posit that change-agents engage with new ideas pragmatically and strategically in their effort to have their economic ideas institutionalized. We argue that in these epistemic battles over new regulation, scientific backing by academia is the key resource determining the outcome. We show that the present reforms implemented internationally follow this pattern. In our analysis we contrast the entire discourse on systemic risk and macroprudential regulation with Borio’s initial 2003 proposal for a macroprudential framework. We find that mostly cross-sectional measures targeted towards increasing the resilience of the financial system rather than inter-temporal measures dampening the financial cycle have been implemented. We provide evidence for the lacking support of new macroprudential thinking within academia and argue that this is partially responsible for the lack of anti-cyclical macroprudential regulation. Most worryingly, the financial cycle is largely absent in the academic discourse and is only tacitly assumed instead of fully fledged out in technocratic discourses, pointing to the possibility that no anti-cyclical measures will be forthcoming.

Der Beitrag analysiert die Voraussetzungen für stabiles Geld und setzt sich dabei grundlegend mit Hayeks Thesen zu alternativen Währungssystemen sowie dessen fundamentaler Kritik an der Möglichkeit zur Gestaltung der Geldpolitik auf wissenschaftlicher Basis auseinander. Er prüft Hayeks Vorschlag zur Entnationalisierung des Geldes und seine Thesen zur Überlegenheit des im privaten Wettbewerb geschaffenen Geldes. In diesem Zusammenhang schlägt der Beitrag einen Bogen zur aktuellen Diskussion über Kryptowährungen und wirft die Frage auf, ob virtuelle Währungen wie etwa Bitcoin geeignet sind, den Hayekschen Währungswettbewerb zu entfalten. Sodann wird im Gegensatz zu Hayeks Forderung nach einer Abschaffung der Zentralbanken deren entscheidende Rolle für anhaltendes Wachstum bei stabilen Preisen skizziert und die Wichtigkeit der Unabhängigkeit von Notenbanken für die dauerhafte Durchführung einer stabilitätsorientierten Geldpolitik hervorgehoben. Gleichwohl ergeht der Hinweis, dass Notenbanken mit der Überschreitung ihres Mandats auf lange Sicht gesehen selbst den Status ihrer Unabhängigkeit unterminieren können und damit die Rückübertragung der Kompetenz für zentrale geldpolitische Entscheidungen auf Regierung und Parlament provozieren. Die Gefahren der weitgehenden Unabhängigkeit einiger weniger an der Spitze der Notenbanken anerkennend wird anschließend die Bedeutung ihrer Rechenschaftspflicht und Transparenz ihrer Entscheidungen unterstrichen.
In the context of Brexit, changes to the regulatory architecture of CCPs that empower the European securities markets regulator are under way to prevent the threat of a regulatory race to the bottom. However, this empowerment currently leaves the national supervision of common European rules within the EU intact. This policy letter argues that supervisory arbitrage is as much a threat within the EU as outside of it, wherefore a common supervision of CCP rules in the EU is called for. The paper traces the origins of the current set-up and criticizes the current regulatory proposal by the EU Commission as too cumbersome while discussing possible ways forward to achieve European supervision. In contrast to the current proposal of the Commission, we call for a unified supervision within ESMA, combined with a European fiscal backstop.
This policy letter provides evidence for the crucial importance of the initial regulatory treatment for the further development of financial innovations by exploring the emergence and initial legal framing of off-balance-sheet leasing in Germany. Due to a missing legal framework, lease contracts occurred as an innovative social practice of off-balance-sheet financing. However, this lacking legal framing impeded the development of this financial innovation as it also created legal uncertainties. This was about to change after the initial legal framing of leasing in the 1970’s which eliminated those legal uncertainties and off-balance-sheet leasing entered into a stunning period of growth while laying the foundation of a regulatory resiliency against efforts that seek to abandon the off-balance-sheet treatment of leases. As the initial legal framing is crucial for the further development of a financial innovation, we propose the French approach for the initial vindication of new financial products in which the principles-based rules are aligned with the capabilities of regulators to intervene, even when a financial innovation complies with the letter of the law. In this way, regulators could regulate the frontier of financial innovations and weed out those which are entirely or mainly driven by regulatory arbitrage considerations while maintaining the beneficial elements of those products.
While the debate about the needs and merits of cryptocurrency regulation is ongoing, the unprecedented price hikes of cryptocurrencies towards the end of 2017 triggered a somewhat unexpected sort of regulation in the form of public statements by governments and financial supervisors. It kicked in rather quickly and turned out to be much more effective than imagined. These interventions can be identified as one of the main factors that drove asset prices down, thereby preventing destabilizing bubbles. The experience of the supervisory response to the cryptocurrency bubble of the past months keeps important insights for any prospective regulation of cryptocurrencies. First, public statements are a highly effective regulatory tool in the short term as they manage market expectations, a fact which is well-known as forward guidance in monetary policy. So far, the legal framework in the EU takes insufficient account of the regulatory role of public statements. Second, regulation needs to keep up with the incredible speed of fintech innovations. Some regulators addressed the challenge by adopting a ‘sandbox’ approach. However, the ‘sandbox’ approach clearly calls for international cooperation. To achieve a balance between safety and innovation, international cooperation should emulate the experimental character of sandboxes. One could conceive of a ‘sandbox for regulators’, an arrangement which would facilitate the exchange of information on regulatory initiatives among authorities but also the coordination of communication and forward guidance.
To estimate demand for labor, we use a combination of detailed employment data and the outcomes of procurement auctions, and compare the employment of the winner of an auction with the employment of the second ranked firm (i.e. the runner-up firm). Assuming similar ex-ante winning probabilities for both firms, we may view winning an auction as an exogenous shock to a firm’s production and its demand for labor. We utilize daily data from almost 900 construction firms and about 3,000 auctions in Austria in the time period 2006 until 2009. Our main results show that the winning firm significantly increases labor demand in the weeks following an auction but only in the years before the recent economic crisis. It employs about 80 workers more after the auction than the runner-up firm. Most of the adjustment takes place within one month after the demand shock. Winners predominantly fire fewer workers after winning than runner-up firms. In the crisis, however, firms do not employ more workers than their competitors after winning an auction. We discuss explanations like labor hoarding and productivity improvements induced by the crisis as well discuss implications for fiscal and stimulus policy in the crisis.
Departing from the principle of absolute priority, CoCo bonds are particularly exposed to bank losses despite not having ownership rights. This paper shows the link between adverse CoCo design and their yields, confirming the existence of market monitoring in designated bail-in debt. Specifically, focusing on the write-down feature as loss absorption mechanism in CoCo debt, I do find a yield premium on this feature relative to equity-conversion CoCo bonds as predicted by theoretical models. Moreover, and consistent with theories on moral hazard, I find this premium to be largest when existing incentives for opportunistic behavior are largest, while this premium is non-existent if moral hazard is perceived to be small. The findings show that write-down CoCo bonds introduce a moral hazard problem in the banks. At the same time, they support the idea of CoCo investors acting as monitors, which is a prerequisite for a meaningful role of CoCo debt in banks' regulatory capital mix.
Bargaining with a bank
(2018)
This paper examines bargaining as a mechanism to resolve information problems. To guide the analysis, I develop a parsimonious model of a credit negotiation between a bank and firms with varying levels of impatience. In equilibrium, impatient firms accept the bank’s offer immediately, while patient firms wait and negotiate price adjustments. I test the empirical predictions using a hand-collected dataset on credit line negotiations. Firms signing the bank’s offer right away draw down their line of credit after origination and default more than late signers. Late signers negotiate price adjustments more frequently, and, consistent with the model, these adjustments predict better ex post performance.
We show that time-varying volatility of volatility is a significant risk factor which affects the cross-section and the time-series of index and VIX option returns, beyond volatility risk itself. Volatility and volatility-of-volatility measures, identified model-free from the option price data as the VIX and VVIX indices, respectively, are only weakly related to each other. Delta-hedged index and VIX option returns are negative on average, and are more negative for strategies which are more exposed to volatility and volatility-of-volatility risks. Volatility and volatility of volatility significantly and negatively predict future delta-hedged option payoffs. The evidence is consistent with a no-arbitrage model featuring time-varying market volatility and volatility-of-volatility factors, both of which have negative market price of risk.
This paper studies the distributional consequences of a systematic variation in expenditure shares and prices. Using European Union Household Budget Surveys and Harmonized Index of Consumer Prices data, we construct household-specific price indices and reveal the existence of a pro-rich inflation in Europe. Particularly, over the period 2001-15, the consumption bundles of the poorest deciles in 25 European countries have, on average, become 10.5 percentage points more expensive than those of the richest decile. We find that ignoring the differential inflation across the distribution underestimates the change in the Gini (based on consumption expenditure) by up to 0.03 points. Cross-country heterogeneity in this change is large enough to alter the inequality ranking of numerous countries. The average inflation effect we detect is almost as large as the change in the standard Gini measure over the period of interest.
The paper analyses the contagion channels of the European financial system through the stochastic block model (SBM). The model groups homogeneous connectivity patterns among the financial institutions and describes the shock transmission mechanisms of the financial networks in a compact way. We analyse the global financial crisis and European sovereign debt crisis and show that the network exhibits a strong community structure with two main blocks acting as shock spreader and receiver, respectively. Moreover, we provide evidence of the prominent role played by insurances in the spread of systemic risk in both crises. Finally, we demonstrate that policy interventions focused on institutions with inter-community linkages (community bridges) are more effective than the ones based on the classical connectedness measures and represents consequently, a better early warning indicator in predicting future financial losses.
The increase in alternative working arrangements has sparked a debate over the positive impact of increased flexibility against the negative impact of decreased financial security. We study the prevalence and determinants of intermediated work in order to document the relative importance of the arguments for and against this recent labor market trend. We link data on individual participation and losses from a Federal Trade Commission settlement with a Multi-Level Marketing firm with detailed county-level information. Participation is greater in middle-income areas and in areas where female labor market non-participation is higher, suggesting that flexibility offers real benefits. However, losses from MLM participation are higher in areas with lower education levels and higher income inequality, suggesting that the downsides of alternative work are particularly high in certain demographics. Our results illustrate that the advantages and disadvantages of alternative work arrangements accrue to different groups.
We develop a simple theoretical model to motivate testable hypotheses about how peer-to-peer (P2P) platforms compete with banks for loans. The model predicts that (i) P2P lending grows when some banks are faced with exogenously higher regulatory costs; (ii) P2P loans are riskier than bank loans; and (iii) the risk-adjusted interest rates on P2P loans are lower than those on bank loans. We confront these predictions with data on P2P lending and the consumer bank credit market in Germany and find empirical support. Overall, our analysis indicates the P2P lenders are bottom fishing when regulatory shocks create a competitive disadvantage for some banks.
In contrast to the popularity of financial education interventions worldwide, studies on the economic effects of those interventions report mixed results. With a focus on the effect on disadvantaged groups, we review both the theoretical and empirical findings in order to understand why this discrepancy exists. The survey first highlights that it is necessary to distinguish between the concepts of, and the relationships between, financial education, financial literacy and financial behavior to identify the true effects of financial education. The review addresses possible biases caused by third factors such as numeracy. Next, we review theories on financial literacy which make clear that the effect of financial education interventions is heterogeneous across the population. Last, we look closely at main empirical studies on financial education targeted at the migrants/immigrants, the low-income earners and the young, and compare their methodologies. There seems to be a positive effect on short-term financial knowledge and awareness of the young, but there is no proven evidence on long-term behavior after being grown up. Studies on financial behavior of migrants and immigrants show almost no effect of financial education.
This paper investigates the effect of the conventional and unconventional (e.g. Quantitative Easing - QE) monetary policy intervention on the insurance industry. We first analyze the impact on the stock performances of 166 (re)insurers from the last QE programme launched by the European Central Bank (ECB) by constructing an event study around the announcement date. Then we enlarge the scope by looking at the monetary policy surprise effects on the same sample of (re)insurers over a timeframe of 12 years, also extending the analysis to the Credit Default Swaps (CDS) market. In the second part of the paper by building a set of balance sheet-based indices, we identify the characteristics of (re)insurers that determine sensitivity to monetary policy actions. Our evidences suggest that a single intervention extrapolated from the comprehensive strategy cannot be utilized to estimate the effect of monetary policy intervention on the market. With respect to the impact of monetary policies, we show how the effect of interventions changes over time. Expansionary monetary policy interventions, when generating an instantaneous reduction of interest rates, generated movement in stock prices in the same direction till September 2010. This effect turned positive during the European sovereign debt crisis. However, the effect faded away in 2014-2015. The pattern is confirmed by the impact on the CDS market. With regard to the determinants of these effects, our analysis suggests that sensitivity is mainly driven by asset allocation and in particular by exposure to fixed income assets.
his paper studies heterogeneity in the reaction to rank feedback. In a laboratory experiment, individuals take part in a series of dynamic real-effort contests with intermediate feedback. To solve the identification problem in estimating the causal effect of rank feedback on subsequent effort provision we implement a random multiplier in the first round of each contest. The realization of this multiplier then serves as a valid instrument for rank feedback. While rank feedback has a robust effect on subsequent effort provision on average, an explicit analysis of between-subject heterogeneity reveals that a substantial fraction of participants in fact react entirely opposite than the aggregated results indicate. We further show that this heterogeneity has consequences for overall outcomes, thereby arguing that heterogeneous sensitivities to rank feedback could have implications for the design of various policies in education and organizations.
With a notional amount outstanding of more than USD 500 trillion, the market for OTC derivatives is of vital importance for global financial stability. A growing proportion of these contracts are cleared via central counterparties (CCPs), which means that CCPs are gaining in importance as critical financial market infrastructures. At the same time, there is growing concern that a new "too big to fail" problem could arise, as the CCP industry is highly concentrated due to economies of scale. From a European perspective, it should be noted that the clearing of euro-denominated OTC derivatives mainly takes place in London, hence outside the EU in the foreseeable future. For some time there has been a controversial discussion as to whether this can remain the case post Brexit.
CCPs, which clear a significant proportion of euro OTC derivatives and are systemically relevant from an EU perspective, should be subject to direct supervision by EU authorities and should be established in the EU. This would represent an important building block for a future Capital Markets Union in Europe, as regulatory or supervisory arbitrage in favour of systemically important third- ountry CCPs could be prevented. In addition, if a systemically relevant CCP handling a considerable portion of the euro OTC derivatives business were to run into serious difficulties, this may impact ECB monetary policy. This applies both to demand for central bank money and to the transmission of monetary policy measures, which can be significantly impaired, particularly in the event that the repo market or payment systems are disrupted. It is therefore essential for the ECB to be closely involved in the supervision of CCPs. Against this background, the draft amendment of EMIR (European Market Infrastructure Regulation) presented on 13 June 2017 is a step in the right direction. In addition, there is an urgent need to introduce a recovery and resolution mechanism for CCPs in the EU to complement the existing single resolution mechanism (SRM) for banks in the eurozone. Only then can the diverse interdependencies between banks and CCPs be adequately taken into account in the recovery and resolution programmes required in a financial crisis.

We investigate whether and how the shift from discretionary forward-looking provisioning to the restrictive incurred loss approach under International Financial Reporting Standards (IFRS) in the European Union (EU) affects the cross-country comparability and predictive ability of loan loss allowances. Given bank supervisors’ keen interest in comparable and adequate loan loss allowances, we also examine the role of supervisors in determining financial statement effects around IFRS adoption. We find that the application of the incurred loss approach has led to more comparable loan loss allowances. However, some differences persist in countries where supervisors were reluctant to enforce the incurred loss approach. Our results also suggest that the predictive ability of loan loss allowances improved following IFRS adoption. Finally, in supplemental analyses we document that increased comparability of loan loss allowances is associated with the cross-country convergence of the risk sensitivity of bank leverage indicating an improvement in the effectiveness of market discipline in the EU.
Even if the importance of micro data transparency is a well-established fact, European institutions are still lacking behind the US when it comes to the provision of financial market data to academics. In this Policy Letter we discuss five different types of micro data that are crucial for monitoring (systemic) risk in the financial system, identifying and understanding inter-linkages in financial markets and thus have important implications for policymakers and regulatory authorities. We come to the conclusion that for all five areas of micro data, outlined in this Policy Letter (bank balance sheet data, asset portfolio data, market transaction data, market high frequency data and central bank data), the benefits of increased transparency greatly offset potential downsides. Hence, European policymakers would do well to follow the US example and close the sizeable gap in micro data transparency. For most cases, relevant data is already collected (at least on national level), but just not made available to academics for partly incomprehensible reasons. Overcoming these obstacles could foster financial stability in Europe and assure level playing fields with US regulators and policymakers.
Does economic policy uncertainty affect household stockholding? To answer this question we create a novel measure of household exposure to economic policy uncertainty news by combining survey information on the hours a household spends in reading newspapers and the frequency of such news in the popular press during a household’s pre-interview period. After controlling for household fixed effects, month-year fixed effects and time-varying cognitive skills, we find that households with a higher exposure to economic policy uncertainty news are less likely to invest in stocks held directly or through mutual funds. This effect is independent from the market volatility index and household (first-moment) expectations about the stock market index.
Germany Inc. was an idiosyncratic form of industrial organization that put financial institutions at the center. This paper argues that the consumption of private benefits in related party transactions by these key agents can be understood as a compensation for their coordinating and monitoring function in Germany Inc. As a consequence, legal tools apt to curb tunneling remained weak in Germany from the perspective of outside shareholders. While banks were in a position to use their firm-level knowledge and influence to limit rent-seeking by other related parties, their own behavior was not subject to meaningful controls. With the dismantling of Germany Inc. banks seized their monitoring function and left an unprecedented void with regard to related party transactions. Hence, a “traditionalist” stance which opposes law reform for related party transactions in Germany negatively affects capital market development, growth opportunities and ultimately social welfare.
We characterize the optimal linear tax on capital in an Overlapping Generations model with two period lived households facing uninsurable idiosyncratic labor income risk. The Ramsey government internalizes the general equilibrium feedback of private precautionary saving. For logarithmic utility our full analytical solution of the Ramsey problem shows that the optimal aggregate saving rate is independent of income risk. The optimal time-invariant tax on capital is increasing in income risk. Its sign depends on the extent of risk and on the Pareto weight of future generations. If the Ramsey tax rate that maximizes steady state utility is positive, then implementing this tax rate permanently generates a Pareto-improving transition even if the initial equilibrium is dynamically efficient. We generalize our results to Epstein-Zin-Weil utility and show that the optimal steady state saving rate is increasing in income risk if and only if the intertemporal elasticity of substitution is smaller than 1.
This paper investigates the roles psychological biases play in empirically estimated deviations between subjective survival beliefs (SSBs) and objective survival probabilities (OSPs). We model deviations between SSBs and OSPs through age-dependent inverse S-shaped probability weighting functions (PWFs), as documented in experimental prospect theory. Our estimates suggest that the implied measures for cognitive weakness, likelihood insensitivity, and those for motivational biases, relative pessimism, increase with age. We document that direct measures of cognitive weakness and motivational attitudes share these trends. Our regression analyses confirm that these factors play strong quantitative roles in the formation of subjective survival beliefs. In particular, cognitive weakness is an increasingly important contributor to the overestimation of survival chances in old age.
This paper is the national report for Germany prepared for the to the 20th General Congress of the International Academy of Comparative Law 2018 and gives an overview of the regulation of crowdfunding in Germany and the typical design of crowdfunding campaigns under this legal framework. After a brief survey of market data, it delineates the classification of crowdfunding transactions in German contract law and their treatment under the applicable conflict of laws regime. It then turns to the relevant rules in prudential banking regulation and capital market law. It highlights disclosure requirements that flow from both contractual obligations of the initiators of campaigns vis-à-vis contributors and securities regulation (prospectus regime). After sketching the most important duties of the parties involved in crowdfunding, the report also looks at the key features of the respective transactions’ tax treatment.
This paper revisits the macroeconomic effects of the large-scale asset purchase programmes launched by the Federal Reserve and the Bank of England from 2008. Using a Bayesian VAR, we investigate the macroeconomic impact of shocks to asset purchase announcements and assess changes in their effectiveness based on subsample analysis. The results suggest that the early asset purchase programmes had significant positive macroeconomic effects, while those of the subsequent ones were weaker and in part not significantly different from zero. The reduced effectiveness seems to reflect in part better anticipation of asset purchase programmes over time, since we find significant positive macroeconomic effects when we consider shocks to survey expectations of the Federal Reserve’s last asset purchase programme. Finally, in all estimations we find a significant and persistent positive impact of asset purchase shocks on stock prices.
Coordination of circuit breakers? Volume migration and volatility spillover in fragmented markets
(2018)
We study circuit breakers in a fragmented, multi-market environment and investigate whether a coordination of circuit breakers is necessary to ensure their effectiveness. In doing so, we analyze 2,337 volatility interruptions on Deutsche Boerse and research whether a volume migration and an accompanying volatility spillover to alternative venues that continue trading can be observed. Different to prevailing theoretical rationale, trading volume on alternative venues significantly decreases during circuit breakers on the main market and we do not find any evidence for volatility spillover. Moreover, we show that the market share of the main market increases sharply during a circuit breaker. Surprisingly, this is amplified with increasing levels of fragmentation. We identify high-frequency trading as a major reason for the vanishing trading activity on the alternative venues and give empirical evidence that a coordination of circuit breakers is not essential for their effectiveness as long as market participants shift to the dominant venue during market stress.
We investigate different designs of circuit breakers implemented on European trading venues and examine their effectiveness to manage excess volatility and to preserve liquidity. Specifically, we empirically analyze volatility and liquidity around volatility interruptions implemented on the German and Spanish stock market which differ regarding specific design parameters. We find that volatility interruptions in general significantly decrease volatility in the post interruption phase. Unfortunately, this decrease in volatility comes at the cost of decreased liquidity. Regarding design parameters, we find tighter price ranges and shorter durations to support volatility interruptions in achieving their goals.
