This paper investigates systemic risk in the insurance industry. We first analyze the systemic contribution of the insurance industry vis-à-vis other industries by applying 3 measures, namely the linear Granger causality test, conditional value at risk and marginal expected shortfall, on 3 groups, namely banks, insurers and non-financial companies listed in Europe over the last 14 years. We then analyze the determinants of the systemic risk contribution within the insurance industry by using balance sheet level data in a broader sample. Our evidence suggests that i) the insurance industry shows a persistent systemic relevance over time and plays a subordinate role in causing systemic risk compared to banks, and that ii) within the industry, those insurers which engage more in non-insurance-related activities tend to pose more systemic risk. In addition, we are among the first to provide empirical evidence on the role of diversification as potential determinant of systemic risk in the insurance industry. Finally, we confirm that size is also a significant driver of systemic risk, whereas price-to-book ratio and leverage display counterintuitive results.
This study examines the role of actual and perceived financial sophistication (i.e., financial literacy and confidence) for individuals' wealth accumulation. Using survey data from the German SAVE initiative, we find strong gender- and education-related differences in the distribution of the two variables and their effects on wealth: As financial literacy rises in formal education, whereas confidence increases in education for men but decreases for women, we observe that women become strongly underconfident with higher education, while men remain overconfident.Regarding wealth accumulation, we show that financial literacy has a positive effect that is stronger for women than for men and that is increasing (decreasing) in education for women (men). Confidence, however, supports only highly-educated men's wealth. When considering different channels for wealth accumulation, we observe that financial literacy is more important for current financial market participation, whereas confidence is more strongly associated with future-oriented financial planning. Overall, we demonstrate that highly-educated men's wealth levels benefit from their overconfidence via all financial decisions considered, but highly-educated women's financial planning suffers from their underconfidence. This may impair their wealth levels in old age.
As the financial crisis gathered momentum in 2007, the United States Federal Reserve brought its policy interest rate aggressively down from 5¼ percent in September 2007 to virtually zero by December 2008. In contrast, although facing the same economic and financial stress, the European Central Bank’s first action was to raise its policy rate in July 2008. The ECB began lowering rates only in October 2008 once near global financial meltdown left it with no choice. Thereafter, the ECB lowered rates slowly, interrupted by more hikes in April and July 2011. We use the “abnormal” increase in stock prices — the rise in the stock price index that was not predicted by the trend in the previous 20 days — to measure the market’s reaction to the announcement of the interest rate cuts. Stock markets responded favorably to the Fed interest rate cuts but, on average, they reacted negatively when the ECB cut its policy rate. The Fed’s early and aggressive rate cuts established its intention to provide significant monetary stimulus. That helped renew market optimism, consistent with the earlier economic recovery. In contrast, the ECB started building its shelter only after the storm had started. Markets interpreted even the simulative ECB actions either as “too little, too late” or as signs of bad news. We conclude that by recognizing the extraordinary nature of the circumstances, the Fed’s response not only achieved better economic outcomes but also enhanced its credibility. The ECB could have acted similarly and stayed true to its mandate. The poorer economic outcomes will damage the ECB’s long-term credibility.
Chen and Zadrozny (1998) developed the linear extended Yule-Walker (XYW) method for determining the parameters of a vector autoregressive (VAR) model with available covariances of mixed-frequency observations on the variables of the model. If the parameters are determined uniquely for available population covariances, then, the VAR model is identified. The present paper extends the original XYW method to an extended XYW method for determining all ARMA parameters of a vector autoregressive moving-average (VARMA) model with available covariances of single- or mixed-frequency observations on the variables of the model. The paper proves that under conditions of stationarity, regularity, miniphaseness, controllability, observability, and diagonalizability on the parameters of the model, the parameters are determined uniquely with available population covariances of single- or mixed-frequency observations on the variables of the model, so that the VARMA model is identified with the single- or mixed-frequency covariances.
It has been forty years since the oil crisis of 1973/74. This crisis has been one of the defining economic events of the 1970s and has shaped how many economists think about oil price shocks. In recent years, a large literature on the economic determinants of oil price fluctuations has emerged. Drawing on this literature, we first provide an overview of the causes of all major oil price fluctuations between 1973 and 2014. We then discuss why oil price fluctuations remain difficult to predict, despite economists’ improved understanding of oil markets. Unexpected oil price fluctuations are commonly referred to as oil price shocks. We document that, in practice, consumers, policymakers, financial market participants and economists may have different oil price expectations, and that, what may be surprising to some, need not be equally surprising to others.
The European Central Bank (ECB) increased the emergency liquidity assistance (ELA) for Greek banks from €50 billion in February 2015 to approximately €90 billion in June 2015. Its actions were accompanied by a discussion among academics, politicians and practitioners regarding the legitimacy of the ELA. Some have even accused the ECB of deliberately delaying the bankruptcy filing of already insolvent Greek banks.
We take the claim regarding insolvency delay as an opportunity to highlight the underlying economics of the ELA program and discuss its legitimacy in the current situation. We start by characterizing the complex interrelationship of the European Union, the ECB and the Greek banks through the lens of financial economics, with a particular focus on the political economy of a monetary union with incomplete fiscal union (or fiscal consolidation). Combining these two issues, we examine the decision of the ECB to continue the provision of ELA to Greek banks. Our conclusions, drawn from the analysis, do not support the claim that the ECB’s actions are consistent with a delayed filing for insolvency.
Von Februar bis Juni 2015 hat die Europäische Zentralbank (EZB) die Notfall-Liquiditätshilfen (emergency liquidity assistance, ELA) für griechische Banken von 50 auf etwa 90 Milliarden Euro ausgeweitet. Dies hat zu einer Diskussion unter Wissenschaftlern, Politikern und Praktikern geführt, ob diese Liquiditätshilfen rechtmäßig sind. Es wurde der Vorwurf erhoben, die EZB trage bewusst zu einer Konkursverschleppung der bereits insolventen griechischen Banken bei.
Wir nehmen diesen Vorwurf zum Anlass, die Grundsätze des ELA-Programms genauer zu betrachten und die Frage zu diskutieren, ob das Programm in der aktuellen Situation rechtmäßig war. Zunächst beschreiben wir hierfür aus finanzwirtschaftlicher Perspektive die komplexe Beziehung zwischen der Europäischen Union, der EZB und den griechischen Banken. Dabei gehen wir insbesondere auf die wirtschaftspolitischen Grundsätze einer Währungsunion mit einer unvollständigen Fiskalunion (oder Haushaltskonsolidierung) ein. Vor diesem Hintergrund analysieren wir dann die Entscheidung der EZB, weiterhin Liquiditätshilfen an griechische Banken bereitzustellen. Wir kommen zu dem Ergebnis, dass das Vorgehen der EZB nicht als Konkursverschleppung zu bezeichnen ist.
Investors and insurance policyholders are often confronted with complex products and providers' opaque organisational structures. At the same time, the possibility that their claims will not be honoured often poses an existential risk. Financial regulation therefore aims at putting in place a financial services framework that will safeguard market processes whilst also protecting consumers. However, benefits of regulation are accompanied by certain risks, as can be exemplified with the case of insurance regulation.
Kapitalanleger wie Versicherungsnehmer werden oft konfrontiert mit komplexen Produkten und nicht durchschaubaren Unternehmensstrukturen der Anbieter. Gleichzeitig stellt die mögliche Nichterfüllung ihrer Ansprüche häufig ein existenzielles Risiko dar. Deshalb ist es Ziel der Finanzregulierung, Rahmenbedingungen im Finanzdienstleistungsbereich zu schaffen, die wirtschaftliche Abläufe gewährleisten und gleichzeitig den Konsumenten schützen. Dem Nutzen der Regulierung stehen aber auch Risiken gegenüber, die im diesem Artikel am Beispiel der Versicherungsregulierung dargelegt werden.
The paper discusses an additional reform proposal for enhancing Social Security solvency which reframes the existing debate in a different light. In our research, we focus on incentives to prolong working years and to delay benefits claiming as a way of sustaining Social Security. Specifically, we analyze how the offer of a budget-neutral, actuarially fair lump sum payment - instead of the current delayed retirement credit – would encourage people to delay claiming their OASI benefits and work longer. The results of our research will be useful for policymakers, namely in (1) measuring who would delay claiming benefits if offered a lump sum instead of higher annuity payments, (2) examining how long they would wait, and (3) how much longer, if at all, they would continue working in the interim.
IFRS 9 introduces new impairment rules responding to the G20 critique that IAS 39 results in the delayed and insufficient recognition of credit losses. In a case study of a Greek government bond for the period 2009 to 2011 when Greece’s credit rating declined sharply, this study highlights the discretion that preparers have when estimating impairments. IFRS 9 relies more on management expectations and will lead to earlier impairments. However, these appear still delayed and low if compared to the fair value losses.
European households face tremendous obstacles when intending to open a savings account outside their home country. The shortage of deposits has become a major reason for banks’ declining loan supply and ultimately is responsible for a substantial part of the investment weakness and GDP decline in affected European countries.
Policy makers have made important efforts to promote European deposit market integration and to stimulate cross border flows of savings within the European Union. But these efforts will only yield the intended benefits if a number of additional non-tariff trade barriers are removed. Currently, these barriers prevent households in surplus countries to transfer their savings to banks in deficit countries where their deposits are most urgently needed.
This Paper gives an overview of the German banking system and current challenges it is facing. It starts with an overview of the so-called ‘Three-Pillar-Banking-System’ and a detailed description of the current structure of the banking system in Germany. A brief comparison of the banking system in Germany with the ones in other European countries points out its uniqueness. The consequences of the financial crisis of 2007/2008 and further challenges for the German banking system are discussed, as well as the the ongoing debate around the question whether the strong government involvement should be sustained.
The Liikanen Group proposes contingent convertible (CoCo) bonds as instruments to enhance financial stability in the banking industry. Especially life insurance companies could serve as CoCo bond holders as they are already the largest purchasers of bank bonds in Europe. The growing number of banks issuing CoCo bonds leads to a rising awareness of these hybrid securities among life insurers as they are increasingly looking for higher?yielding investments into bond?like asset classes during the current low interest rate period. Our contribution provides an insight for life insurance companies to understand the effects of holding CoCo bonds as implied by the Solvency II standards that will become effective by 2016.
The global financial crisis (as well as the European sovereign debt crisis) has led to a substantial redesign of rules and institutions – aiming in particular at underwriting financial stability. At the same time, the crisis generated a renewed interest in properly appraising systemic financial vulnerabilities. Employing most recent data and applying a variety of largely only recently developed methods we provide an assessment of indicators of financial stability within the Euro Area. Taking a “functional” approach, we analyze comprehensively all financial intermediary activities, regardless of the institutional roof – banks or non-bank (shadow) banks – under which they are conducted. Our results reveal a declining role of banks (and a commensurate increase in non-bank banking). These structural shifts (between institutions) are coincident with regulatory and supervisory reforms (implemented or firmly anticipated) as well as a non-standard monetary policy environment. They might, unintendedly, actually imply a rise in systemic risk. Overall, however, our analyses suggest that financial imbalances have been reduced over the course of recent years. Hence, the financial intermediation sector has become more resilient. Nonetheless, existing (equity) buffers would probably not suffice to face substantial volatility shocks.
There is a large, but yet growing debate about the need to complement the European monetary union with a stronger fiscal union. This paper reviews the potential trade-offs between effectiveness, moral hazard problems, and permanent redistribution. In particular, we contribute to the question of how member states may be willing to enter into a stronger fiscal union if the evolution of this union may imply large redistribution under incomplete contracting. We discuss clawback mechanisms that have been suggested in the literature, but conclude that clawbacks are undesirable, as they would essentially destroy the insurance value of a fiscal union. Instead, we propose that a clearly defined exit option as a guarantee against involuntary redistribution can make entry into a stronger fiscal union less risky and hence more attractive for member states.
Euro crash risk

A premise of the capabilities perspective in strategy is that firm-specific capabilities allow some firms to be unusually adept at exploiting growth opportunities. Since few firms have the capacity to internally generate the quantity or variety of strategic resources needed to exploit growth opportunities, the ability to externally acquire complementary resources is critical to the acquisition of competitive advantage. However, the external sourcing of resources exposes the firm’s strategic resources to risks of expropriation. We argue this threat gives capable firms incentive to use internally generated strategic resources to pursue growth opportunities before turning to external sources. A pecking order theory of strategic resource deployment is implied. Data from a 22-year sample of cross-border investment partnership decisions made by U.S.-based venture capital firms lend support to our theory.
We investigate the effect of the tone of news on investor stock price expectations and beliefs. In an experimental study we ask subjects to estimate a future stock price for twelve real listed companies. As additional information we provide them with historical stock prices and extracts from real newspaper articles. We propose a way to manipulate the tone of news extracts without distorting its content. Subjects in different treatment groups read news items that are written either in positive or negative tone for each stock. We find that subjects tend to predict a significantly higher (lower) return for stocks after reading positive (negative) tone news. The effect is especially pronounced for stocks with poor past performance. Subjects are more likely to be optimistic (pessimistic) about the economy and to buy (sell) stocks after reading positive (negative) than negative (positive) tone news. Our results show that the news media might affect not only how investors perceive information, but also what they do in response to it.
We present an accessible narrative of the Turkish economy since its great 2001 crisis. We broadly survey economic developments and pay particular attention to monetary policy. The data suggests that the Central Bank of Turkey was a strong inflation targeter early in this period but began to pay less attention to inflation after 2009. Loss of the strong nominal anchor is visible in the break we estimate in Taylor-type rules as well as in asset prices. We also argue that recent discrete jumps in Turkish asset prices, especially the exchange value of the lira, are due more to domestic factors. In the post-2009 period the Central Bank was able to stabilize expectations and asset prices when it chose to do so, but this was the exception rather than the rule.
We show that the size of collateralized household debt determines an economy’s vulnerability to crises of confidence. The house price feeds back on itself by contributing to a liquidity effect, which operates through the value of housing in a collateral constraint. Over a specific range of debt levels this liquidity feedback effect is strong enough to give rise to multiplicity of house prices. In a dynamic setup, we conceptualize confidence as a realization of rationally entertainable belief-weightings of multiple future prices. This delivers debt-level-dependent bounds on the extent to which confidence may drive house prices and aggregate consumption.
Signaling cooperation
(2015)
We examine what an applicant’s vita signals to potential employers about her willingness to cooperate in teams. Intensive social engagement may credibly reveal that an applicant cares about the well-being of others and therefore is less likely to free-ride in teamwork situations. We find that contributions in a public goods game strongly increase in a subject’s degree of social engagement as indicated on her résumé (and rated by an independent third party). Engagement in other domains, such as student or sports associations, is not positively correlated with contributions. In a prediction experiment with human resource managers from various industries, we find that managers use résumé content effectively to predict relative differences in subjects’ willingness to cooperate. Thus, young professionals signal important behavioral characteristics to potential employers through the choice of their extracurricular activities.
We offer evidence of a new stylized feature of corporate financing decisions: the tendency of managers to rely more on debt financing when earnings prospects are poor. We term this 'leaning against the wind' and consider three possible explanations: market timing, precautionary financing, and 'making the numbers'. We find no evidence in favor of the first two hypotheses, and provisionally accept the 'making the numbers' hypothesis that managers who are under pressure because of unrealistically optimistic earnings expectations by analysts and deteriorating real opportunities, will rely more heavily on debt financing to boost earnings per share and return on equity.
We build a novel leading indicator (LI) for the EU industrial production (IP). Differently from previous studies, the technique developed in this paper is able to produce an ex-ante LI that is immune to “overlapping information drawbacks”. In addition, the set of variables composing the LI relies on a dynamic and systematic criterion. This ensures that the choice of the variables is not driven by subjective views. Our LI anticipates swings (including the 2007-2008 crisis) in the EU industrial production – on average – by 2 to 3 months. The predictive power improves if the indicator is revised every five or ten years. In a forward-looking framework, via a general-to-specific procedure, we also show that our LI represents the most informative variable in approaching expectations on the EU IP growth.
The interbank market is important for the efficient functioning of the financial system, transmission of monetary policy and therefore ultimately the real economy. In particular, it facilitates banks' liquidity management. This paper aims at extending the literature which views interbank markets as mutual liquidity insurance mechanism by taking into account persistence of liquidity shocks. Following a theory of long-term interbank funding a financial system which is modeled as a micro-founded agent based complex network interacting with a real economic sector is developed. The model features interbank funding as an over-the-counter phenomenon and realistically replicates financial system phenomena of network formation, monetary policy transmission and endogenous money creation. The framework is used to carry out an optimal policy analysis in which the policymaker maximizes real activity via choosing the optimal interest rate in a trade-off between loan supply and financial fragility. It is shown that the interbank market renders the financial system more efficient relative to a setting without mutual insurance against persistent liquidity shocks and therefore plays a crucial role for welfare.
This paper undertakes a quantitative investigation of the effects of anticipated inflation on the distribution of household wealth and welfare. Consumer Finance Data on household financial wealth suggests that about a third of the US population holds all its financial assets in transaction accounts. The remaining two-third of the US population holds most of their financial assets outside transaction accounts. To account for this evidence, I introduce a portfolio choice in a standard incomplete markets model with heterogeneous agents. I calibrate the model economy to SCF 2010 US data and use this environment to study the distributive effects of changes in anticipated inflation. An increase in anticipated inflation leads households to reshuffle their portfolio towards real assets. This crowding-in of supply for real assets lowers equilibrium interest rates and thereby redistributes wealth from creditors to borrowers. Because borrowers have a higher marginal utility, this redistribution improves aggregate welfare. First, this paper shows that inflation acts not only a regressive consumption tax as in Erosa and Ventura (2002), but also as a progressive tax. Second, this paper shows that the welfare cost of inflation are even lower than the estimates computed by Lucas (2000) and Ireland (2009). Finally, this paper offers insights into why deflationary environments should be avoided.
We study the life cycle of portfolio allocation following for 15 years a large random sample of Norwegian households using error-free data on all components of households’ investments drawn from the Tax Registry. Both, participation in the stock market and the portfolio share in stocks, have important life cycle patterns. Participation is limited at all ages but follows a hump-shaped profile which peaks around retirement; the share invested in stocks among the participants is high and flat for the young but investors start reducing it as retirement comes into sight. Our data suggest a double adjustment as people age: a rebalancing of the portfolio away from stocks as they approach retirement, and stock market exit after retirement. Existing calibrated life cycle models can account for the first behavior but not the second. We show that incorporating in these models a reasonable per period participation cost can generate limited participation among the young but not enough exit from the stock market among the elderly. Adding also a small probability of a large loss when investing in stocks, produces a joint pattern of participation and of the risky asset share that resembles the one observed in the data. A structural estimation of the relevant parameters that target simultaneously the portfolio, participation and asset accumulation age profiles of the model reveals that the parameter combination that fits the data best is one with a relatively large risk aversion, small participation cost and a yearly large loss probability in line with the frequency of stock market crashes in Norway.
n this paper we analyze an economy with two heterogeneous investors who both exhibit misspecified filtering models for the unobservable expected growth rate of the aggregated dividend. A key result of our analysis with respect to long-run investor survival is that there are degrees of model misspecification on the part of one investor for which there is no compensation by the other investor's deficiency. The main finding with respect to the asset pricing properties of our model is that the two dimensions of asset pricing and survival are basically independent. In scenarios when the investors are more similar with respect to their expected consumption shares, return volatilities can nevertheless be higher than in cases when they are very different.
We analyze the macroeconomic implications of increasing the top marginal income tax rate using a dynamic general equilibrium framework with heterogeneous agents and a fiscal structure resembling the actual U.S. tax system. The wealth and income distributions generated by our model replicate the empirical ones. In two policy experiments, we increase the statutory top marginal tax rate from 35 to 70 percent and redistribute the additional tax revenue among households, either by decreasing all other marginal tax rates or by paying out a lump-sum transfer to all households. We find that increasing the top marginal tax rate decreases inequality in both wealth and income but also leads to a contraction of the aggregate economy. This is primarily driven by the negative effects that the tax change has on top income earners. The aggregate gain in welfare is sizable in both experiments mainly due to a higher degree of distributional equality.
IT-driven trading innovations offer institutional investors alternative trading channels to broker delegated order handling. Motivated by the impact on intermediation relationships in securities trading and the adoption rate of such trading channels, the new option of self-directed order handling is analyzed. To capture the prerequisites for institutional investors to insource their order handling, an order-channel management (OCM) framework is introduced. It is based on a structural approach to account for the increasing complexity in comparison to traditional intermediary services. Drivers for the adoption of an OCM framework are investigated from the strategic perspective. Operational OCM is based on the business value of IT analysis of distinct trading innovations. It includes smart order router technology, low latency technology as an upgrade for existing IT-driven trading channels as well as negotiation dark pools, representing alternative trading venues. Evidence that all investigated IT-driven trading innovations generate additional business value is provided as one result. However, it is also shown that they exhibit entry barriers tightly related to investor size. Further, Task-Technology Fit is proven to be the major driver for the adoption decision. Consequently, IT-driven trading innovations should increase trading control, satisfy high anonymity and varying urgency demands.
There is a growing debate about complementing the European Monetary Union by a more comprehensive fiscal union. Against this background, this paper emphasizes that there is a trade-off in designing a system of fiscal transfers ("fiscal capacity") in a union between members of different size. A system cannot guarantee symmetric treatment of members and simultaneously ensure a balanced budget. We compute hypothetical transfers for the Eurozone members from 2001 to 2012 to illustrate this trade-off. Interestingly, a symmetric system that treats shocks in small and large countries symmetrically would have produced large budgetary surpluses in 2009, the worst year of the financial crisis.
Mehr als 18 Milliarden Euro hat die Commerzbank im Zuge der Finanzkrise in Form von staatlichen Garantien, Kapitalspritzen oder Einlagen erhalten. Auch die Hypo Real Estate, die WestLB, die SachsenLB und die IKB profitierten von Stützungsmaßnahmen. Die EU genehmigte diese und andere staatlichen Hilfsmaßnahmen. Grundsätzlich sind staatliche Stützungsmaßnahmen jedoch als wirtschaftlicher Vorteil zu werten und damit zunächst eine verbotene Beihilfe. In seinem Working Paper betrachtet Tuschl die rechtlichen Grundlagen des EU-Beihilferechts und zeigt die teilweise differierende Praxis der EU-Kommission auf.
The Federal Reserve’s muddled mandate to attain simultaneously the incompatible goals of maximum employment and price stability invites short-term-oriented discretionary policymaking inconsistent with the systematic approach needed for monetary policy to contribute best to the economy over time. Fear of liftoff—the reluctance to start the process of policy normalization after the end of a recession—serves as an example. Causes of the problem are discussed, drawing on public choice and cognitive psychology perspectives. The Federal Reserve could adopt a framework that relies on a simple policy rule subject to periodic reviews and adaptation. Replacing meeting-by-meeting discretion with a simple policy rule would eschew discretion in favor of systematic policy. Periodic review of the rule would allow the Federal Reserve the flexibility to account for and occasionally adapt to the evolving understanding of the economy. Congressional legislation could guide the Federal Reserve in this direction. However the Federal Reserve may be best placed to select the simple rule and could embrace this improvement on its own, within its current mandate, with the publication of a simple rule along the lines of its statement of longer-run goals.
This paper investigates the effect of a change in informational environment of borrowers on the organizational design of bank lending. We use micro-data from a large multinational bank and exploit the sudden introduction of a credit registry, an information-sharing mechanism across banks, for a subset of borrowers. Using within borrower and loan officer variation in a difference-in-difference empirical design, we show that expansion of credit registry led to an improvement in allocation of credit to affected
borrowers. There was a concurrent change in the organizational structure of the bank that involved a dramatic increase in delegation of lending decisions of affected borrowers to loan officers. We also find a significant expansion in scope of activities of loan officers who deal primarily with affected borrowers, as well as of their superiors. There is suggestive evidence that larger banks in the economy were better able to implement similar changes as our bank. We argue that these patterns can be understood within the framework of incentive-based and information cost processing theories. Our findings could help rationalize why improvements in the information environment of borrowers may be altering the landscape of lending by moving decisions outside the boundaries of financial intermediaries.
This chapter outlines the conditions under which accounting-based smoothing can be beneficial for policyholders who hold with-profit or participating payout life annuities (PLAs). We use a realistically-calibrated model of PLAs to explore how alternative accounting techniques influence policyholder welfare as well as insurer profitability and stability. We find that accounting smoothing of participating life annuities is favorable to consumers and insurers, as it mitigates the impact of short-term volatility and enhances the utility of these long-term annuity contracts.
We investigate the determinants of firms’ implicit insurance to employees, using a difference-in-difference approach: we rely on differences between family and non-family firms to identify the supply of insurance, and exploit variation in unemployment insurance across and within countries to gauge workers’ demand for insurance. Using a firm-level panel from 41 countries, we find that family firms feature more stable employment, greater wage flexibility and lower labor cost than non-family ones. Employment stability in family firms is greater, and the wage discount larger, in countries with more generous public unemployment insurance: private and public provision of employment insurance are substitutes.
We propose a multivariate dynamic intensity peaks-over-threshold model to capture extreme events in a multivariate time series of returns. The random occurrence of extreme events exceeding a threshold is modeled by means of a multivariate dynamic intensity model allowing for feedback effects between the individual processes. We propose alternative specifications of the multivariate intensity process using autoregressive conditional intensity and Hawkes-type specifications. Likewise, temporal clustering of the size of exceedances is captured by an autoregressive multiplicative error model based on a generalized Pareto distribution. We allow for spillovers between both the intensity processes and the process of marks. The model is applied to jointly model extreme returns in the daily returns of three major stock indexes. We find strong empirical support for a temporal clustering of both the occurrence of extremes and the size of exceedances. Moreover, significant feedback effects between both types of processes are observed. Backtesting Value-at-Risk (VaR) and Expected Shortfall (ES) forecasts show that the proposed model does not only produce a good in-sample fit but also reliable out-of-sample predictions. We show that the inclusion of temporal clustering of the size of exceedances and feedback with the intensity thereof results in better forecasts of VaR and ES.
Expectations of Sterling returning to Gold have been disregarded in empirical work on the US dollar – Sterling exchange rate in the early 1920s. We incorporate such considerations in a PPP model of the exchange rate, letting the probability of a return to gold follow a logistic function. We draw several conclusions: (i) the PPP model works well from spring 1919 to spring 1925; (ii) wholesale prices outperform consumer prices; (iii) allowing for a return to gold leads to a higher speed of adjustment of the exchange rate to PPP; (iv) interest rate differentials and the relative monetary base are crucial determinants of the expected return to gold; (v) the probability of a return to Gold peaked at about 72% in late 1924 and but fell to about 60% in early 1925; and (vi) our preferred model does not support the Keynes’ view that Sterling was overvalued after the return to gold.
Since the 1970s, the overarching view in the literature has been that a Phillips curve relationship did not exist in Ireland prior to the 1979 exchange rate break with Sterling. It was argued that, as a small open economy, prices were determined externally. To test this relationship, we study the determination of inflation between 1926 and 2012, a longer sample period than any previously used. We find that the difference between unemployment and the NAIRU is a significant determinant of inflation both in the full sample and in the subsamples spanning the periods before and after the Sterling parity link.
In this paper we assemble an annual data set on broad and narrow money, prices, real economic activity and interest rates in Ireland from a variety of sources for the period 1933-2012. We discuss in detail how the data set is constructed and what assumptions we have made to do so. Furthermore, we estimate a simple SVAR model to provide some empirical evidence on the behaviour of these time series. Money supply shocks appear to be the most important drivers of both money and prices. Interest rate shocks, which capture monetary policy, play an important role driving output and, of course, interest rates. The GDP shocks, which raise prices, seem of less importance.
We model education as an investment in human capital that, like other investments, is appropriately evaluated in a framework that accounts for risk as well as return. In contrast to dominant wage-premia approach to calculating the returns to education, but which implicitly ignores risk, we evaluate the returns by treating the value of human capital as the price of a non-tradable risky asset. We do so using a lifecycle framework that incorporates risk preferences and earnings risk, as well as a progressive income tax and social insurance system. Our baseline estimate is that a college degree provides a $440K dollar increase in annual certainty-equivalent consumption. Although significantly smaller than traditional estimates of the value of education, these returns are still large enough to offset both the direct and indirect cost of college education for a large range of plausible preference parameters. Importantly, however, we find that accounting for risk reverses the finding from the education wage-premia literature regarding the trends in the returns to education. In particular, we find that the risk-adjusted gains from college completion actually decreased rather than increased in the recent period. Overall, our results show the importance of earnings risks in assessing the value of education.
We examine how U.S. monetary policy affects the international activities of U.S. Banks. We access a rarely studied US bank‐level dataset to assess at a quarterly frequency how changes in the U.S. Federal funds rate (before the crisis) and quantitative easing (after the onset of the crisis) affects changes in cross‐border claims by U.S. banks across countries, maturities and sectors, and also affects changes in claims by their foreign affiliates. We find robust evidence consistent with the existence of a potent global bank lending channel. In response to changes in U.S. monetary conditions, U.S. banks strongly adjust their cross‐border claims in both the pre and post‐crisis period. However, we also find that U.S. bank affiliate claims respond mainly to host country monetary conditions.
No. And not only for the reason you think. In a world with multiple inefficiencies the single policy tool the central bank has control over will not undo all inefficiencies; this is well understood. We argue that the world is better characterized by multiple inefficiencies and multiple policy makers with various objectives. Asking the policy question only in terms of optimal monetary policy effectively turns the central bank into the residual claimant of all policy and gives the other policymakers a free hand in pursuing their own goals. This further worsens the tradeoffs faced by the central bank. The optimal monetary policy literature and the optimal simple rules often labeled flexible inflation targeting assign all of the cyclical policymaking duties to central banks. This distorts the policy discussion and narrows the policy choices to a suboptimal set. We highlight this issue and call for a broader thinking of optimal policies.
We examine firms’ simultaneous choice of investment, debt financing and liquidity in a large sample of US corporates between 1980 and 2014. We partition the sample according to the firms’ financial constraints and their needs to hedge against future shortfalls in operating income. In contrast to earlier work, our joint estimation approach shows that cash flows affect the corporate decisions of unconstrained firms more strongly than those of constrained firms. Investment-cash flow sensitivities are particularly intense for unconstrained firms with high hedging needs. Investment opportunities (as proxied by Q), however, play a larger role for constrained firms with the effects being strongest in case of low hedging needs. Interestingly, constrained firms with low hedging needs are found to employ more debt to finance their investment opportunities and build up significant cash holdings at the same time. Our results hence indicate overinvestment behavior for unconstrained firms but no underinvestment for constrained firms if they have low hedging needs.
We develop a dynamic recursive model where political and economic decisions interact, to study how excessive debt-GDP ratios affect political sustainability of prudent fiscal policies. Rent seeking groups make political decisions – to cooperate (or not) – on the allocation of fiscal budgets (including rents) and issuance of sovereign debt. A classic commons problem triggers collective fiscal impatience and excessive debt issuing, leading to a vicious circle of high borrowing costs and sovereign default. We analytically characterize debt-GDP thresholds that foster cooperation among rent seeking groups and avoid default. Our analysis and application helps in understanding the politico-economic sustainability of sovereign rescues, emphasizing the need for fiscal targets and possible debt haircuts. We provide a calibrated example that quantifies the threshold debt-GDP ratio at 137%, remarkably close to the target set for private sector involvement in the case of Greece.
In 2000 Italy replaced its traditional system of severance pay for public employees with a new system. Under the old regime, severance pay was proportional to the final salary before retirement; under the new regime it is proportional to lifetime earnings. This reform entails substantial losses for future generations of public employees, in the range of €20,000-30,000, depending on seniority. Using a difference-in-difference framework, we estimate the impact of this unanticipated change in lifetime resources, on the current consumption and wealth accumulation of employees affected by the reform. In line with theoretical simulations, we find that each euro reduction in severance pay reduces the average propensity to consume by 3 cents and increases the wealth-income ratio by 0.32. The response is stronger for younger workers and for households where both spouses are public sector employees.
We examine the inter-linkages between financial factors and real economic activity. We review the main theoretical approaches that allow financial frictions to be embedded into general equilibrium models. We outline, from a policy perspective, the most recent empirical papers focusing on the propagation of exogenous shocks to the economy, with a particular emphasis on works dealing with time variation of parameters and other types of nonlinearities. We then present an application to the analysis of the changing transmission of financial shocks in the euro area. Results show that the effects of a financial shock are time-varying and contingent on the state of the economy. They are of negligible importance in normal times but they greatly matter in conditions of stress.
Demographic change belongs to the mega-trends of the 20th and the 21st century. The ongoing aging process in major industrialized countries gives rise to the relative scarcity of raw labor and the relative abundance of physical capital. Standard macroeconomic models suggest that this depresses asset returns and increases wages which, in turn, provides incentives for more human capital accumulation. This thesis quantifies the macroeconomic effects of demographic change and reveals the importance of human capital adjustments for price and welfare effects within and across generations. Chapter 1 investigates the distributions of income, skills, and welfare in the German economy along the inter- and the intra-generational dimension. It shows that demographic change leads to a more capital- and skill-intensive economy and that high-school households loose compared to college households in terms of welfare. Chapter 2 disentangles the effect of demographic change on returns to risk-free and risky assets in the U.S. and measures the net effect on the equity premium. It shows that both returns decline while the equity premium increases slightly. Endogenous human capital adjustments are crucial for relatively small effects. Chapter 3 develops a method for computing transitional dynamics in heterogeneous agent models with aggregate risk if these transitions are induced by exogenous deterministic dynamics such as demographic change. The application of the method to a simple illustrative example shows a large reduction in total computing time while approximation errors are small.
Challenging voluntary CSR-initiatives – a case study on the effectiveness of the Equator Principles
(2015)
The Equator Principles (EPs) are a voluntary and self-regulatory Corporate Social Responsibility (CSR) initiative in the field of project finance. The EPs provide a number of principles to businesses to reduce the negative impacts of lending practices linked to environment-damaging projects. The paper argues that the actual impact of the EPs even now as revised version is still limited. This is due to their voluntary nature and their lack of adequate governance mechanisms, that is, enforcement, monitoring and sanctioning. With the help of RepRisk, which provides a database capturing third-party criticism as well as a company’s or project’s exposure to controversial socio-environmental issues, the paper evaluates the on-the-ground performances of the two ‘Equator banks’ Barclays and JPMorgan Chase and compares their performance with the one of the two non-Equator banks Deutsche Bank and UBS. The paper shows that the EPs do not have a substantial influence on the broader CSR-performance of multinational banks due to the EPs’ limited scope – focusing mainly on project finance – and the (still) existing various loopholes, grey areas and discretionary leeway. The paper also gives an overview of the main institutional shortcomings of the EPs and their association and discusses some potential reform steps which should be taken to further strengthen and ‘harden’ this ‘soft law’ EP-framework. The paper thus argues in favor of (more) mandatory and legally binding rules and standards at the transnational level to overcome the EPs’ ‘voluntariness bias’.

We analyze the macroeconomic implications of increasing the top marginal income tax rate using a dynamic general equilibrium framework with heterogeneous agents and a fiscal structure resembling the actual U.S. tax system. The wealth and income distributions generated by our model replicate the empirical ones. In two policy experiments, we increase the statutory top marginal tax rate from 35 to 70 percent and redistribute the additional tax revenue among households, either by decreasing all other marginal tax rates or by paying out a lump-sum transfer to all households. We find that increasing the top marginal tax rate decreases inequality in both wealth and income but also leads to a contraction of the aggregate economy. This is primarily driven by the negative effects that the tax change has on top income earners. The aggregate gain in welfare is sizable in both experiments mainly due to a higher degree of distributional equality.
This paper looks into the specific influence that the European banking union will have on (future) bank client relationships. It shows that the intended regulatory influence on market conditions in principle serves as a powerful governance tool to achieve financial stability objectives.
From this vantage, it analyzes macro-prudential instruments with a particular view to mortgage lending markets – the latter have been critical in the emergence of many modern financial crises. In gauging the impact of the new European supervisory framework, it finds that the ECB will lack influence on key macro-prudential tools to push through more rigid supervisory policies vis-à-vis forbearing national authorities.
Furthermore, this paper points out that the current design of the European bail-in tool supplies resolution authorities with undue discretion. This feature which also afflicts the SRM imperils the key policy objective to re-instill market discipline on banks’ debt financing operations. The latter is also called into question because the nested regulatory technique that aims at preventing bail-outs unintendedly opens additional maneuvering space for political decision makers.
In Absatz 3 des Artikel 136 des Vertrags über die Arbeitsweise der EU (AEUV) wurde für die Verwendung von ESM Geldern festgelegt, dass diese nur dann zur Gewährung von Finanzhilfen verwendet werden dürfen, wenn „... dies unabdingbar ist, um die Stabilität des Euro-Währungsgebiets insgesamt zu wahren." Im vorliegenden Artikel argumentiert Alfons Weichenrieder, dass die nach dem griechischen Referendum entstandene Situation, die Stabilität des “Euro-Währungsgebiets insgesamt" nicht bedroht, so dass die Vergabe von neuen Krediten, zumal diese voraussichtlich unter weichen und im Zweifel nicht durchsetzbaren Auflagen vergeben würden, ein offensichtlicher Verstoß gegen die Grundlagen des ESM wäre.
In this statement the European Shadow Financial Regulatory Committee (ESFRC) is advocating a conditional relief of Greek’s government debt based on Greece meeting certain targets for structural economic reforms in areas such as its labor market and pensions sector.The authors argue that the position of the European institutions that debt relief for Greece cannot be part of an agreement is based on the illusion that Greece will be able to service its sovereign debt and reduce its debt overhang after implementing a set of fiscal and structural reforms. However, the Greek economy would need to grow at an unrealistig level to achieve debt sustainability soley on the basis of reforms.The authors therefore view a substantial debt relief as inevitable and argue that three questions must be resolved urgently, in order to structure debt relief adequately: First, which groups must accept losses associated with debt relief. Second, how much debt relief should be offered. Third, under what conditions should relief be offered.
In light of the failed negotiations with Greece, Jan Krahnen argues that an effective reform agenda for Greece can only be designed by the elected government. Fundamental reforms will take time to take full effect and euro area member states will, in the meantime, have to offer Greece a basic level of economic security.
Krahnen demands that policy makers and the professional public involved view the Greek crisis as an opportunity to take the next necessary steps to formulate a reform agenda for the European Monetary Union. A community of supranational and non-party researchers and intellectuals could take the initiative and in a structured process develop a trustworthy and realistic concept that drafts the next big step towards a political union of Europe, including elements of a fiscal union.
Mit Blick auf die gescheiterten Verhandlungen mit Griechenland, argumentiert Jan Krahnen im vorliegenden Policy Beitrag, dass eine zielführende Reformagenda nur von der gewählten Regierung Griechenlands formuliert werden kann. Die Euro-Staaten müssten Griechenland für die Zeitdauer einer Restrukturierungszeit eine Grundsicherung zusagen. Die EU-Staaten fordert Krahnen dazu auf, aus der Griechenlandkrise die notwendigen Konsequenzen zu ziehen. Auch die Eurozone brauche eine effektive Reformagenda. Die Verschuldungsdynamik innerhalb der Währungsunion, deren Auswüchse am Beispiel Griechenlands besonders deutlich werden, könne bei fehlendem guten Willen nur durch eine politische Union und eine in sie eingebettete Fiskalunion aufgelöst werden. Krahnen argumentiert, dass ein Weiterverhandeln über Restrukturierungsauflagen aus der derzeitigen verfahrenen Situation nicht herausführen wird. Entscheidend sei, ein mehr oder weniger umfassendes Paket zu schnüren, das Elemente eines teilweisen internationalen Haftungsverbunds mit Elementen eines partiellen nationalen Souveränitätsverzichts verbindet.
Negative Zinsen auf Einlagen – juristische Hindernisse und ihre wettbewerbspolitischen Auswirkungen
(2015)
Im anhaltenden Niedrigzinsumfeld tun Banken sich schwer damit, die ihnen zur Verfügung gestellte Liquidität einer renditeträchtigen Nachfrage zuzuführen. Darüberhinaus müssen sie auf Liquiditätsüberschüsse, die im Rahmen der Einlagenfazilität des Eurosystems über Nacht bei den nationalen Zentralbanken der Eurozone deponiert werden, Strafzinsen entrichtet. Vor diesem Hintergrund könnten Banken durch negative Einlagenzinsen das Anliegen verfolgen, die Nachfrage nach Aufbewahrung von (Sicht)Einlagen zu verringern. Einer solchen Strategie stehen aber aus juristischer Sicht Hindernisse entgegen, soweit der beschriebene Paradigmenwechsel auch im Rahmen existierender Kundenbeziehungen einseitig vorgenommen werden soll. Die rechtlichen Hürden sind weder Ausdruck einer realitätsfernen Haarspalterei, noch eines verbraucherschützenden Furors. Vielmehr ermöglichen sie privaten und gewerblichen Bankkunden, im Zeitpunkt der angestrebten Zinsanpassung bewusst über die Verwendung ihrer liquiden Mittel zu entscheiden.
We study the effect of weakening creditor rights on distress risk premia via a bankruptcy reform that shifts bargaining power in financial distress toward shareholders. We find that the reform reduces risk factor loadings and returns of distressed stocks. The effect is stronger for firms with lower firm-level shareholder bargaining power. An increase in credit spreads of riskier relative to safer firms, in particular for firms with lower firm-level shareholder bargaining power, confirms a shift in bargaining power from bondholders to shareholders. Out-of-sample tests reveal that a reversal of the reform's effects leads to a reversal of factor loadings and returns.

When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations. We derive the equilibrium dynamics in closed form and show that joint presence of both risks leads to over-proportional risk exposure for households. This implies that the whole benefit from insurance through social security is greater than the sum of the benefits from insurance against each of the two risks in isolation. We measure this through interaction effects which appear even though the two risks are orthogonal by construction. While the interactions unambiguously increase the welfare benefits from insurance, they can in- or decrease the welfare costs from crowding out of capital formation. The net effect depends on the relative strengths of the opposing forces.
We investigate the relationship between anchoring and the emergence of bubbles in experimental asset markets. We show that setting a visual anchor at the fundamental value (FV) in the first period only is sufficient to eliminate or to significantly reduce bubbles in laboratory asset markets. If no FV-anchor is set, bubble-crash patterns emerge. Our results indicate that bubbles in laboratory environments are primarily sparked in the first period. If prices are initiated around the FV, they stay close to the FV over the entire trading horizon. Our insights can be related to initial public offerings and the interaction between prices set on pre-opening markets and subsequent intra-day price dynamics.
The pressure on tax haven countries to engage in tax information exchange shows first effects on capital markets. Empirical research suggests that investors do react to information exchange and partially withdraw from previous secrecy jurisdictions that open up to information exchange. While some of the economic literature emphasizes possible positive effects of tax havens, the present paper argues that proponents of positive effects may have started from questionable premises, in particular when it comes to the effects that tax havens have for emerging markets like China and India.
n this paper we compute the optimal tax and education policy transition in an economy where progressive taxes provide social insurance against idiosyncratic wage risk, but distort the education decision of households. Optimally chosen tertiary education subsidies mitigate these distortions. We highlight the importance of two different channels through which academic talent is transmitted across generations (persistence of innate ability vs. the impact of parental education) for the optimal design of these policies and model different forms of labor as imperfect substitutes, thereby generating general equilibrium feedback effects from policies to relative wages of skilled and unskilled workers. We show that subsidizing higher education has important redistributive benefits, by shrinking the college wage premium in general equilibrium. We also argue that a full characterization of the transition path is crucial for policy evaluation. We find that optimal education policies are always characterized by generous tuition subsidies, but the optimal degree of income tax progressivity depends crucially on whether transitional costs of policies are explicitly taken into account and how strongly the college premium responds to policy changes in general equilibrium.

In an experimental setting in which investors can entrust their money to traders, we investigate how compensation schemes affect liquidity provision and asset prices. Investors face a trade-off between risk and return. At the benefit of a potentially higher return, they can entrust their money to a trader. However this investment is risky, as the trader might not be trustworthy. Alternatively, they can opt for a safe but low return. We study how subjects solve this trade-off when traders are either liable for losses or not, and when their bonuses are either capped or not. Limited liability introduces a conflict of interest because it makes traders value the asset more than investors. To limit losses, investors should thus restrict liquidity provision to force traders to trade at a lower price. By contrast, bonus caps make traders value the asset less than investors. This should encourage liquidity provision and decrease prices. In contrast to these predictions, we find that under limited liability investors contribute to asset price bubbles by increasing liquidity provision and that caps fail to tame bubbles. Overall, giving investors skin in the game fosters financial stability.
Since August 2009, German legislation allows for voluntary Say on Pay Votes (SoPV) during Annual General Meetings (AGMs). We examine 1,169 AGMs of all German listed firms with more than 10,000 agenda items over the period 2010-2013 to identify (1) determinants and approval rates of voluntary SoPVs, (2) the effect of voluntary SoPVs on AGM participation, and (3) the effect of SoP on executive compensation. Our data reveals that in the first four years of the voluntary say on pay regime every second firm in our sample has opted for having a SoPV. The propensity for a SoPV increases with firm size, abnormal executive compensation and free float of shares. Indeed, smaller firms with concentrated ownership do not only have a lower propensity for a SoPV, but also show a higher propensity to opt for only limited disclosure of executive compensation. Approval rates of SoPVs are lower than the approval rate for the average AGM agenda item and this effect is stronger in (i) widely held firms as well as in (ii) firms with abnormal executive compensation. Additionally, SoPVs actually can increase AGM participation; however, this result is particularly evident for widely held firms. Finally, we find stronger pay for performance elements within total executive compensation, particularly when the effect of executive compensation is lagged over the years following the vote. Overall, our results are consistent with the view that firms use voluntary SoPV to gain legitimation for executive remuneration policies in firms with low ownership concentration. This is enforced, where (small) shareholders consider executive compensation a part of the agency problem of listed firms, and where (small) shareholders consider SoPVs as a possibility to actively influence corporate decisions, with these decisions leading to a higher degree of alignment between executive management boards and shareholders.
The standard view suggests that removing barriers to entry and improving judicial enforcement reduces informality and boosts investment and growth. However, a general equilibrium approach shows that this conclusion may hold to a lesser extent in countries with a constrained supply of funds because of, for example, a more concentrated banking sector or lower financial openness. When the formal sector grows larger in those countries, more entrepreneurs become creditworthy, but the higher pressure on the credit market limits further capital accumulation. We show empirical evidence consistent with these predictions.
Empirical credit demand analysis undertaken at the aggregate level obscures potential behavioral heterogeneity between various borrowing sectors. Looking at disaggregated data and analyzing bank loans to non-financial companies, to financial companies, to households for consumption and for house purchases separately with respect to a common set of macroeconomic determinants may facilitate more accurate empirical relationships and more reliable insights for economic policy. Using quarterly Euro area panel data between 2003 and 2013, empirical evidence for heterogeneity in borrowing behavior across sectors and the credit cycle with respect to interest rates, output and house prices is found. The results motivate sector-specific, counter-cyclical capital requirements.
This paper empirically investigates how organizational hierarchy affects the allocation of credit within a bank. Using an exogenous variation in organizational design, induced by a reorganization plan implemented in roughly 2,000 bank branches in India during 1999-2006, and employing a difference-in-differences research strategy, we find that increased hierarchization of a branch decreases its ability to produce "soft" information on loans, leads to increased standardization of loans and rationing of "soft information" loans. Furthermore, this loss of information brings about a reduction in performance on loans: delinquency rates and returns on similar loans are worse in more hierarchical branches. We also document how hierarchical structures perform better in environments that are characterized by a high degree of corruption, thus highlighting the benefits of hierarchical decision making in restraining rent seeking activities. Finally, we document a channel - managerial interference - through which hierarchy affects loan outcomes.
Our paper evaluates recent regulatory proposals mandating the deferral of bonus payments and claw-back clauses in the financial sector. We study a broadly applicable principal agent setting, in which the agent exerts effort for an immediately observable task (acquisition) and a task for which information is only gradually available over time (diligence). Optimal compensation contracts trade off the cost and benefit of delay resulting from agent impatience and the informational gain. Mandatory deferral may increase or decrease equilibrium diligence depending on the importance of the acquisition task. We provide concrete conditions on economic primitives that make mandatory deferral socially (un)desirable.
In its meeting on 6 September 2012, the Governing Council of the ECB took decisions on a number of technical features regarding the Eurosystem’s outright transactions in secondary sovereign bond markets (OMT). This decision was challenged in the German Federal Constitutional Court (GFCC) by a number of constitutional complaints and other petitions. In its seminal judgment of 14 January 2014, the German court expressed serious doubts on the compatibility of the ECB’s decision with the European Union law.
It admitted the complaints and petitions even though actual purchases had not been executed and the control of acts of an organ of the EU in principle is not the task of the GFCC. As justification for this procedure the court resorted to its judicature on a reserved “ultra vires” control and the defense of the “constitutional identiy” of Germany. In the end, however, the court referred the case pursuant to Article 267 TFEU to the European Court of Justice (ECJ) for preliminary rulings on several questions of EU law. In substance, the German court assessed OMT as an act of economic policy which is not covered by the competences of the ECB. Furthermore, it judged OMT as a – by EU primary law – prohibited monetary financing of sovereign debt. The defense of the ECB (disruption of monetary policy transmission mechanism) was dismissed without closer scrutiny as being “irrelevant”. Finally the court opened, however, a way for a compromise by an interpretation of OMT in conformity with EU law under preconditions, specified in detail.
Procedure and findings of this judgment were harshly criticized by many economists but also by the majority of legal scholars. This criticism is largely convincing in view of the admissibility of the complaints. Even if the “ultra vires” control is in conformity with prior decisions of court it is in this judgment expanded further without compelling reasons. It is also questionable whether the standing of the complaining parties had to be accepted and whether the referral to the ECJ was indicated. The arguments of the court are, however, conclusive in respect of the transgression of competences by the ECB and – to somewhat lesser extent – in respect of the monetary debt financing. The dismissal of the defense as “irrelevant” is absolutey persuasive.
The Treaty of Maastricht imposed the strict obligation on the European Union (EU) to establish an economic and monetary union, now Article 3(4) TEU. This economic and monetary union is, however, not designed as a separate entity but as an integral part of the EU. The single currency was to become the currency of the EU and to be the legal tender in all Member States unless an exemption was explicitly granted in the primary law of the EU, as in the case of the UK and Denmark. The newly admitted Member States are obliged to introduce the euro as their currency as soon as they fulfil the admission criteria. Technically, this has been achieved by transferring the exclusive competence for the monetary policy of the Member States whose currency is the euro on the EU, Article 3(1)(c) TFEU and by bestowing the euro with the quality of legal tender, the only legal tender in the EU, Article 128(1) sentence 3 TFEU.
Savings accounts are owned by most households, but little is known about the performance of households’ investments. We create a unique dataset by matching information on individual savings accounts from the DNB Household Survey with market data on account-specific interest rates and characteristics. We document considerable heterogeneity in returns across households, which can be partly explained by financial sophistication. A one-standard deviation increase in financial literacy is associated with a 13% increase compared to the median interest rate. We isolate the usage of modern technology (online accounts) as one channel through which financial literacy has a positive association with returns.
A theory of the boundaries of banks with implications for financial integration and regulation
(2015)
We offer a theory of the "boundary of the
rm" that is tailored to banking, as it builds on a single ine¢ ciency arising from risk-shifting and as it takes into account both interbank lending as an alternative to integration and the role of possibly insured deposit funding. Amongst others, it explains both why deeper economic integration should cause also greater financial integration through both bank mergers and interbank lending, albeit this typically remains ine¢ ciently incomplete, and why economic disintegration (or "desychronization"), as currently witnessed in the European Union, should cause less interbank exposure. It also suggests that recent policy measures such as the preferential treatment of retail deposits, the extension of deposit insurance, or penalties on "connectedness" could all lead to substantial welfare losses.
n the EU there are longstanding and ongoing pressures towards a tax that is levied on the EU level to substitute for national contributions. We discuss conditions under which such a transition can make sense, starting from what we call a "decentralization theorem of taxation" that is analogous to Oates (1972) famous result that in the absence of spill-over effects and economies of scale decentralized public good provision weakly dominates central provision. We then drop assumptions that turn out to be unnecessary for this results. While spill-over effects of taxation may call for central rules for taxation, as long as spill-over effects do not depend on the intra-regional distribution of the tax burden, decentralized taxation plus tax coordination is found superior to a union-wide tax.
Do markets correct individual behavioral biases? In an experimental asset market, we compare the outcomes of a standard market economy to those of a an island economy that removed market interactions. We observe asset price bubbles in the market economy while prices are stable in the island economy. We also find that subjects took more risk following larger losses, resulting in larger prices and consistent with a gambling for resurrection motive. This motive can translate into bubbles in the market economy because higher prices increase average losses and thus reinforce the desire to resurrect. By contrast, the absence of such a strategic complementarity in island economies can explain the more stable outcome. These results suggest that markets do not correct behavioral biases, rather the contrary.
This paper analyzes sovereign risk shift-contagion, i.e. positive and significant changes in the propagation mechanisms, using bond yield spreads for the major eurozone countries. By emphasizing the use of two econometric approaches based on quantile regressions (standard quantile regression and Bayesian quantile regression with heteroskedasticity) we find that the propagation of shocks in euro's bond yield spreads shows almost no presence of shift-contagion. All the increases in correlation we have witnessed over the last years come from larger shocks propagated with higher intensity across Europe.
Research on interbank networks and systemic importance is starting to recognise that the web of exposures linking banks balance sheets is more complex than the single-layer-of-exposure paradigm. We use data on exposures between large European banks broken down by both maturity and instrument type to characterise the main features of the multiplex structure of the network of large European banks. This multiplex network presents positive correlated multiplexity and a high similarity between layers, stemming both from standard similarity analyses as well as a core-periphery analyses of the different layers. We propose measures of systemic importance that fit the case in which banks are connected through an arbitrary number of layers (be it by instrument, maturity or a combination of both). Such measures allow for a decomposition of the global systemic importance index for any bank into the contributions of each of the sub-networks, providing a useful tool for banking regulators and supervisors. We use the dataset of exposures between large European banks to illustrate the proposed measures.
Although banks are at the center of systemic risk, there are other institutions that contribute to it. With the publication of the leveraged lending guideline in March 2013, the U.S. regulators show that they are especially worried about the private equity firms with their high-risk deals. Given these risks and the interconnectedness of the banks through the LBO loan syndicates, I shed light on the impact of a bank’s LBO loan exposure on its systemic risk. By using 3,538 observations between 2000 and 2013 from 165 global banks, I show that banks with higher LBO exposure also have a higher level of systemic risk. Other loan purposes do not show this positive relationship. The main drivers influencing this relationship positively are the bank’s interconnectedness to other LBO financing banks and its size. Lending experience with a specific PE sponsor, experience with leading LBO syndicates or a bank’s credit rating, however, lead to a lower impact of the LBO loan exposure on systemic risk.
In the mid-1990s, institutional investors entered the syndicated loan market and started to serve borrowers as lead arrangers. Why are non-banks able to compete for this role against banks? How do the composition of syndicates and loan pricing differ among lead arrangers? By using a dataset of 12,847 leveraged loans between 1997 and 2012, I aim to answer these questions. Non-banks benefit from looser regulatory requirements, have industry expertise which helps them in the screening and monitoring of borrowers and focus on firms that ask for loans only instead of additional cross-selling of other services. I can show that non-banks specialize on more opaque and less experienced borrowers, are more likely than banks to choose participants that help to reduce potentially higher information asymmetries and earn 105 basis points more than banks.
This paper analyzes the influence Leveraged Buyouts (LBOs) have on the operating performance of the LBO target companies’ direct competitors. A unique and hand-collected data set on LBOs in the United States in the period 1985-2009 allows us to analyze the effects different restructuring activities as part of the LBO have on the competitors’ revenues. These restructuring activities include changes to leverage, governance, or operating business, as well as M&A activities of the LBO target company. We find that although LBOs itself have a negative influence on competitors’ revenue growth, some restructuring mechanisms might actually benefit competing companies.
The Liikanen Group proposes contingent convertible (CoCo) bonds as a potential mechanism to enhance financial stability in the banking industry. Especially life insurance companies could serve as CoCo bond holders as they are already the largest purchasers of bank bonds in Europe. We develop a stylized model with a direct financial connection between banking and insurance and study the effects of various types of bonds such as non-convertible bonds, write-down bonds and CoCos on banks' and insurers' risk situations. In addition, we compare insurers' capital requirements under the proposed Solvency II standard model as well as under an internal model that ex-ante anticipates additional risks due to possible conversion of the CoCo bond into bank shares. In order to check the robustness of our findings, we consider different CoCo designs (write-down factor, trigger value, holding time of bank shares) and compare the resulting capital requirements with those for holding non-convertible bonds. We identify situations in which insurers benefit from buying CoCo bonds due to lower capital requirements and higher coupon rates. Furthermore, our results highlight how the Solvency II standard model can mislead insurers in their CoCo investment decision due to economically irrational incentives.
