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.
