Households buy life insurance as part of their liquidity management. The option to surrender such a policy can serve as a buffer when a household faces a liquidity need. In this study, we investigate empirically which individual and household specific sociodemographic factors influence the surrender behavior of life insurance policyholders. Based on the Socio-Economic Panel (SOEP), an ongoing wide-ranging representative longitudinal study of around 11,000 private households in Germany, we construct a proxy to identify life insurance surrender in the data. We use this proxy to conduct fixed effect regressions and support the results with survival analyses. We find that life events that possibly impose a liquidity shock to the household, such as birth of a child and divorce increase the likelihood to surrender an existing life insurance policy for an average household in the panel. The acquisition of a dwelling and unemployment are further aspects that can foster life insurance surrender. Our results are robust with respect to different models and hold conditioning on region specific trends; they vary however for different age groups. Our analyses contribute to the existing literature supporting the emergency fund hypothesis. The findings obtained in this study can help life insurers and regulators to detect and understand industry specific challenges of the demographic change.

Higher capital ratios are believed to improve system-wide financial stability through three main channels: (i) higher loss-absorption capacity, (ii) lower moral hazard, (iii) stabilization of the financial cycle if capital ratios are increased during good times. We examine these mechanisms in a laboratory asset market experiment with indebted participants. We find support for the loss-absorption channel: higher capital ratios reduce the bankruptcy rate. However, we do not find support for the moral hazard channel. Higher capital ratios (insignificantly) increase asset price bubbles, an aggregate measure of excessive risk-taking. Additional evidence suggests that bankruptcy aversion explains this surprising result. Finally, the evidence supports the idea that higher capital ratios in good times stabilize the financial cycle.
Zum ersten Mal wurde in Deutschland eine groß angelegte wissenschaftliche Studie zur Machbarkeit und zum Nutzen einer säulenübergreifenden Renteninformationsplattform durchgeführt, unter realen Bedingungen und mit mehreren tausend Teilnehmern. Die beiden zentralen Ergebnisse sind, dass ein elektronisches Rentencockpit auch in Deutschland technisch machbar ist und beträchtlichen individuellen Zusatznutzen für die Bürgerinnen und Bürger stiften würde. Die Langfristanalysen der Pilotstudie zeigen, dass selbst die einmalige Schaffung von Rententransparenz für viele Teilnehmer Anlass genug ist, ihren Rentenplan zu überdenken und sich aktiv mit ihrer Altersvorsorge auseinanderzusetzen und ihr Verhalten zu ändern. Teilnehmer mit Zugang zu einem elektronischen Rentencockpit fühlen sich nach der Studie deutlich besser informiert und neigen dazu ihr Sparverhalten stärker anzupassen als Personen ohne Zugang. Die außerordentlich hohe Bereitschaft zur Teilnahme und die Antworten in den Online-Befragungen sind zudem Beleg für den großen Bedarf an systemgestützter, individueller Rententransparenz. Soll ein Rentencockpit Verbreitung in Deutschland finden, scheint eine automatisierte, elektronische Bereitstellung von Vertragsdaten von Seiten der Rententräger jedoch unabdingbar, da die eigenständige Suche und teilmanuelle Bereitstellung von Standmitteilungen für die meisten Studienteilnehmer ein großes Hindernis darstellt.
Much ado about nothing : a study of differential pricing and liquidity of short and long term bonds
(2018)
Are yields of long-maturity bonds distorted by demand pressure of clientele investors, regulatory effects, or default, flight-to-safety or liquidity premiums? Using data on German nominal bonds between 2005 and 2015, we study the differential pricing and liquidity of short and long maturity bonds. We find statistically significant, but economically negligible segmentation in yields and some degree of liquidity segmentation of short-term versus long-term bonds. These results have important policy implications for the e17.5 trillion European pension and insurance industries: long maturity bond yields seem appropriate for the valuation of long-term liabilities.
A number of recent studies have concluded that consumer spending patterns over the month are closely linked to the timing of income receipt. This correlation is interpreted as evidence of hyperbolic discounting. I re-examine patterns of spending in the diary sample of the U.S. Consumer Expenditure Survey, incorporating information on the timing of the main consumption commitment for most households - their monthly rent or mortgage payment. I find that non-durable and food spending increase with 30-48% on the day housing payments are made, with smaller increases in the days after. Moreover, households with weekly, biweekly and monthly income streams but the same timing of rent/mortgage payments have very similar consumption patterns. Exploiting variation in income, I find that households with extra liquidity decrease non-durable spending around housing payments, especially those households with a large budget share of housing.
Asset transaction prices sampled at high frequency are much staler than one might expect in the sense that they frequently lack new updates showing zero returns. In this paper, we propose a theoretical framework for formalizing this phenomenon. It hinges on the existence of a latent continuous-time stochastic process pt valued in the open interval (0; 1), which represents at any point in time the probability of the occurrence of a zero return. Using a standard infill asymptotic design, we develop an inferential theory for nonparametrically testing, the null hypothesis that pt is constant over one day. Under the alternative, which encompasses a semimartingale model for pt, we develop non-parametric inferential theory for the probability of staleness that includes the estimation of various integrated functionals of pt and its quadratic variation. Using a large dataset of stocks, we provide empirical evidence that the null of the constant probability of staleness is fairly rejected. We then show that the variability of pt is mainly driven by transaction volume and is almost unaffected by bid-ask spread and realized volatility.
Through the lens of market participants' objective to minimize counterparty risk, we provide an explanation for the reluctance to clear derivative trades in the absence of a central clearing obligation. We develop a comprehensive understanding of the benefits and potential pitfalls with respect to a single market participant's counterparty risk exposure when moving from a bilateral to a clearing architecture for derivative markets. Previous studies suggest that central clearing is beneficial for single market participants in the presence of a sufficiently large number of clearing members. We show that three elements can render central clearing harmful for a market participant's counterparty risk exposure regardless of the number of its counterparties: 1) correlation across and within derivative classes (i.e., systematic risk), 2) collateralization of derivative claims, and 3) loss sharing among clearing members. Our results have substantial implications for the design of derivatives markets, and highlight that recent central clearing reforms might not incentivize market participants to clear derivatives.
A tale of one exchange and two order books : effects of fragmentation in the absence of competition
(2018)
Exchanges nowadays routinely operate multiple, almost identically structured limit order markets for the same security. We study the effects of such fragmentation on market performance using a dynamic model where agents trade strategically across two identically-organized limit order books. We show that fragmented markets, in equilibrium, offer higher welfare to intermediaries at the expense of investors with intrinsic trading motives, and lower liquidity than consolidated markets. Consistent with our theory, we document improvements in liquidity and lower profits for liquidity providers when Euronext, in 2009, consolidated its order ow for stocks traded across two country-specific and identically-organized order books into a single order book. Our results suggest that competition in market design, not fragmentation, drives previously documented improvements in market quality when new trading venues emerge; in the absence of such competition, market fragmentation is harmful.
This paper presents new evidence on the expectation formation process from a Dutch household survey. Households become too optimistic about their future income after their income has improved, consistent with the over-extrapolation of their experience. We show that this effect of experience is persistent and that households over-extrapolate income losses more than income gains. Furthermore, older households over-extrapolate more, suggesting that they did not learn over time to form more accurate expectations. Finally, we study the relationship between expectation errors and consumption. We find that more over-optimistic households intend to consume more and subsequently report higher consumption, even though they do not consume as much as they intended to. These results suggests that overextrapolation hurts consumers and amplify business cycles.
This paper argues that the introduction of the Banking Recovery and Resolution Directive (BRRD) improved market discipline in the European bank market for unsecured debt. The different impact of the BRRD on bank bonds provides a quasi-natural experiment that allows to study the effect of the BRRD within banks using a difference-in-difference approach. Identification is based on the fact that (otherwise identical) bonds of a given bank maturing before 2016 are explicitly protected from BRRD bail-in. The empirical results are consistent with the hypothesis that debt holders actively monitor banks and that the BRRD diminished bail-out expectations. Bank bonds subject to BRRD bail-in carry a 10 basis points bail-in premium in terms of the yield spread. While there is some evidence that the bail-in premium is more pronounced for non-GSIB banks and banks domiciled in peripheral European countries, weak capitalization is the main driver.
The authors relax the standard assumption in the dynamic stochastic general equilibrium (DSGE) literature that exogenous processes are governed by AR(1) processes and estimate ARMA (p,q) orders and parameters of exogenous processes. Methodologically, they contribute to the Bayesian DSGE literature by using Reversible Jump Markov Chain Monte Carlo (RJMCMC) to sample from the unknown ARMA orders and their associated parameter spaces of varying dimensions.
In estimating the technology process in the neoclassical growth model using post war US GDP data, they cast considerable doubt on the standard AR(1) assumption in favor of higher order processes. They find that the posterior concentrates density on hump-shaped impulse responses for all endogenous variables, consistent with alternative empirical estimates and the rigidities behind many richer structural models. Sampling from noninvertible MA representations, a negative response of hours to a positive technology shock is contained within the posterior credible set. While the posterior contains significant uncertainty regarding the exact order, the results are insensitive to the choice of data filter; this contrasts with the authors’ ARMA estimates of GDP itself, which vary significantly depending on the choice of HP or first difference filter.
What institutional arrangements for an independent central bank with a price stability mandate promote good policy outcomes when unconventional policies become necessary? Unconventional monetary policy poses challenges. The large scale asset purchases needed to counteract the zero lower bound on nominal interest rates have uncomfortable fiscal and distributional consequences and require central banks to assume greater risks on their balance sheets.
In his paper, Athanasios Orphanides draws lessons from the experience of the Bank of Japan (BoJ) since the late 1990s for the institutional design of independent central banks. He comes to the conclusion that lack of clarity on the precise definition of price stability, coupled with concerns about the legitimacy of large balance sheet expansions, hinders policy: It encourages the central bank to eschew the decisive quantitative easing needed to reflate the economy and instead to accommodate too-low inflation. The BoJ’s experience with the zero lower bound suggests important benefits from a clear definition of price stability as a symmetric 2% goal for inflation, which the Bank adopted in 2013.
Für Zwecke des privaten Konsums werden ständig Gegenwarts- und Zukunftsgüter bewertet und gehandelt. Ein zuverlässiges und umfassendes Maß für die allgemeine Kaufkraft des Geldes und deren Veränderung sollte diesem Grundsachverhalt Rechnung tragen. Im Unterschied zu konventionellen statistischen Verbraucherpreisindizes ist ein ökonomischer Lebenskostenindex intertemporal angelegt, da er die effektiven Konsumgüterpreise (Effektivpreise) über den Planungshorizont der privaten Haushalte bündelt. Ein Preisstabilitätsstandard, der diesen Zusammenhang ausblendet, ist tendenziell verzerrt und leistet einer asymmetrischen Geldpolitik Vorschub.
Effektivpreise sind Gegenwartspreise für künftigen Konsum, sie berücksichtigen Güterpreise und Zinsen bzw. Vermögenspreisänderungen, sind konsumtheoretisch und wohlfahrtsökonomisch fundiert und bilden die zentralen Bausteine für die Modellklasse der ökonomischen Lebenskostenindizes. Nutzentheoretisch gesehen sind Effektivpreise bewerteter Grenznutzen der letzten konsumierten Gütereinheit, und die daraus abgeleiteten Effektiven Inflationsraten sind intertemporale Grenzraten der Substitution.
Die Autoren entwickeln einen intertemporalen Lebenskostenindex auf der Grundlage des Konzepts der Effektivpreise und stellen empirische Zeitreihen und kohortenspezifische Szenarioanalysen für Deutschland vor.
The paper illustrates based on an example the importance of consistency between the empirical measurement and the concept of variables in estimated macroeconomic models. Since standard New Keynesian models do not account for demographic trends and sectoral shifts, the authors proposes adjusting hours worked per capita used to estimate such models accordingly to enhance the consistency between the data and the model. Without this adjustment, low frequency shifts in hours lead to unreasonable trends in the output gap, caused by the close link between hours and the output gap in such models.
The retirement wave of baby boomers, for example, lowers U.S. aggregate hours per capita, which leads to erroneous permanently negative output gap estimates following the Great Recession. After correcting hours for changes in the age composition, the estimated output gap closes gradually instead following the years after the Great Recession.
Helmut Siekmann erläutert in seinem Beitrag die Einstandspflicht der Bundesrepublik Deutschland für die Deutsche Bundesbank und die Europäische Zentralbank. Dabei kommt er zu dem Schluss, dass weder eine „Haftung der Bundesrepublik Deutschland für Verluste der EZB noch eine Verpflichtung zur Auffüllung von aufgezehrtem Eigenkapital“ besteht.
Dieser Beitrag ist zuerst erschienen in: Festschrift für Theodor Baums zum siebzigsten Geburtstag, S. 1145-1179, Helmut Siekmann, Andreas Cahn, Tim Florstedt, Katja Langenbucher, Julia Redenius-Hövermann, Tobias Tröger, Ulrich Segna, Hrsg., Tübingen, Mohr Siebeck 2017
Financial market interactions can lead to large and persistent booms and recessions. Instability is an inherent threat to economies with speculative financial markets. A central bank’s interest rate setting can amplify the expectation feedback in the financial market and this can lead to unstable dynamics and excess volatility. The paper suggests that policy institutions may be well-advised to handle tools like asset price targeting with care since such instruments might add a structural link between asset prices and macroeconomic aggregates. Neither stock prices nor indices are a good indicator to base decisions on.
The level of capital tax gains has high explanatory power regarding the question of what drives economic inequality. On this basis, the authors develop a simple, yet micro-founded portfolio selection model to explain the dynamics of wealth inequality given empirical tax series in the US. The results emphasize that the level and the transition of speed of wealth inequality depend crucially on the degree of capital taxation. The projections predict that – continuing on the present path of capital taxation in the US – the gap between rich and poor is expected to shrink whereas “massive” tax cuts will further increase the degree of wealth concentration.
Über Scheinriesen: Was TARGET-Salden tatsächlich bedeuten : eine finanzökonomische Überprüfung
(2018)
Der TARGET-Saldo der Bundesbank beläuft sich gegenwärtig auf knapp 1 Billion Euro. Kritikern zufolge birgt dieser Umstand hohe Lasten und Risiken für den deutschen Steuerzahler und zeigt, dass Deutschland zu einem „Selbstbedienungsladen“ im Eurosystem geworden sei. Vor diesem Hintergrund erörtert das Papier im Detail, wie TARGET-Salden überhaupt entstehen und was sie finanzökonomisch bedeuten. Die wirtschaftspolitische Analyse kommt zu dem Schluss, dass - anders als von den Kritikern behauptet- unter den Bedingungen einer Währungsunion im Normalbetrieb - TARGET-Salden lediglich Verrechnungssalden ohne weitere Implikationen sind, die aber nützliche Informationen über ökonomisch tieferliegende, regionale Verschiebungen geben können. Unter dem Extremszenario eines Zerfalls der Währungsunion können TARGET-Salden zwar als offene Positionen interpretiert werden, deren spätere Erfüllung würde aber ähnlich dem Brexit von komplizierten politischen Verhandlungen abhängen, sodass über die Werthaltigkeit allenfalls spekuliert werden kann. Sollte man das Extremszenario für bedeutend halten, und politisches Handeln fordern, erscheinen zwei Lösungen sinnvoll. Beide Vorschläge führen zu einer institutionellen Stärkung der Eurozone: i) die Einführung einer Tilgungspraxis, wie sie im US-amerikanischen Fedwire-System angewandt wird. Dabei handelt es sich um eine rein fiktive Tilgung in Form einer Umbuchung auf einem gemeinsamen (Offenmarkt-)Konto bei der EZB; ii) die Bündelung aller monetären Aktivitäten bei der EZB, sodass eine regionale Abgrenzung von Zahlungsvorgängen entfällt (und damit die TARGET-Salden verschwinden), weil alle Banken in direkter Beziehung zu ein und derselben Zentralbank stehen und der Zahlungsverkehr direkt zwischen den beteiligten Banken stattfindet.
We study the introduction of single-market liquidity provider incentives in fragmented securities markets. Specifically, we investigate whether fee rebates for liquidity providers enhance liquidity on the introducing market and thereby increase its competitiveness and market share. Further, we analyze whether single-market liquidity provider incentives increase overall market liquidity available for market participants. Therefore, we measure the specific liquidity contribution of individual markets to the aggregate liquidity in the fragmented market environment. While liquidity and market share of the venue introducing incentives increase, we find no significant effect for turnover and liquidity of the whole market.
We study the impact of transparency on liquidity in OTC markets. We do so by providing an analysis of liquidity in a corporate bond market without trade transparency (Germany), and comparing our findings to a market with full post-trade disclosure (the U.S.). We employ a unique regulatory dataset of transactions of German financial institutions from 2008 until 2014 to find that: First, overall trading activity is much lower in the German market than in the U.S. Second, similar to the U.S., the determinants of German corporate bond liquidity are in line with search theories of OTC markets. Third, surprisingly, frequently traded German bonds have transaction costs that are 39-61 bp lower than a matched sample of bonds in the U.S. Our results support the notion that, while market liquidity is generally higher in transparent markets, a sub-set of bonds could be more liquid in more opaque markets because of investors "crowding" their demand into a small number of more actively traded securities.
This paper analyzes how the combination of borrowing constraints and idiosyncratic risk affects the equity premium in an overlapping generations economy. I find that introducing a zero-borrowing constraint in an economy without idiosyncratic risk increases the equity premium by 70 percent, which means that the mechanism described in Constantinides, Donaldson, and Mehra (2002) is dampened because of the large number of generations and production. With social security the effect of the zero-borrowing constraint is a lot weaker. More surprisingly, when I introduce idiosyncratic labor income risk in an economy without a zero-borrowing constraint, the equity premium increases by 50 percent, even though the income shocks are independent of aggregate risk and are not permanent. The reason is that idiosyncratic risk makes the endogenous natural borrowing limits much tighter, so that they have a similar effect to an exogenously imposed zero-borrowing constraint. This intuition is confirmed when I add idiosyncratic risk in an economy with a zero-borrowing constraint: neither the equity premium nor the Sharpe ratio change, because the zero-borrowing constraint is already tighter than the natural borrowing limits that result when idiosyncratic risk is added.
We propose a spatiotemporal approach for modeling risk spillovers using time-varying proximity matrices based on observable financial networks and introduce a new bilateral specification. We study covariance stationarity and identification of the model, and analyze consistency and asymptotic normality of the quasi-maximum-likelihood estimator. We show how to isolate risk channels and we discuss how to compute target exposure able to reduce system variance. An empirical analysis on Euro-area cross-country holdings shows that Italy and Ireland are key players in spreading risk, France and Portugal are the major risk receivers, and we uncover Spain's non-trivial role as risk middleman.
We show that bond purchases undertaken in the context of quantitative easing efforts by the European Central Bank created a large mispricing between the market for German and Italian government bonds and their respective futures contracts. On top of the direct effect the buying pressure exerted on bond prices, we show three indirect effects through which the scarcity of bonds, resulting from the asset purchases, drove a wedge between the futures contracts and the underlying bonds: the deterioration of bond market liquidity, the increased bond specialness on the repurchase agreement market, and the greater uncertainty about bond availability as collateral.
We study the role of various trader types in providing liquidity in spot and futures markets based on complete order-book and transactions data as well as cross-market trader identifiers from the National Stock Exchange of India for a single large stock. During normal times, short-term traders who carry little inventory overnight are the primary intermediaries in both spot and futures markets, and changes in futures prices Granger-cause changes in spot prices. However, during two days of fast crashes, Granger-causality ran both ways. Both crashes were due to large-scale selling by foreign institutional investors in the spot market. Buying by short-term traders and cross-market traders was insufficient to stop the crashes. Mutual funds, patient traders with better trade-execution quality who were initially slow to move in, eventually bought sufficient quantities leading to price recovery in both markets. Our findings suggest that market stability requires the presence of well-capitalized standby liquidity providers.
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.

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?
(2018)
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.
