his paper analyses the consumption-investment problem of a loss averse investor equipped with s-shaped utility over consumption relative to a time-varying reference level. Optimal consumption exceeds the reference level in good times and descend to the subsistence level in bad times. Accordingly, the optimal portfolio is dominated by a mean-variance component in good times and rebalanced more aggressively toward stocks in bad times. This consumption-investment strategy contrasts with customary portfolio theory and is consistent with several recent stylized facts about investors' behaviour. I also analyse the joint effect of loss aversion and persistence of the reference level on optimal choices. Finally, the strategy of the loss averse investor outperforms the conventional Merton-style strategies in bad times, but tend to be dominated by the conventional strategies in good times.
We introduce long-run investment productivity risk in a two-sector production economy to explain the joint behavior of macroeconomic quantities and asset prices. Long-run productivity risk in both sectors, for which we provide economic and empirical justification, acts as a substitute for shocks to the marginal efficiency of investments in explaining the equity premium and the stock return volatility differential between the consumption and the investment sector. Moreover, adding moderate wage rigidities allows the model to reproduce the empirically observed positive co-movement between consumption and investment growth.
This paper introduces endogenous preference evolution into a Lucas-type economy and explores its consequences for investors' trading strategy and the dynamics of asset prices. In equilibrium, investors herd and hold the same portfolio of risky assets which is biased toward stocks of sectors that produce a socially preferred good. Price-dividend ratios, expected returns and return volatility are all time varying. In this way, preference evolution helps rationalize the observed under-performance and local biases of investors' portfolios and many empirical regularities of stock returns such a time variation, the value-growth effect and stochastic volatility.

We investigate the role of competition on the outcome of Austrian Treasury auctions. Austria's EU accession led to an increase in the number of banks participating in treasury auctions. We use structural estimates of bidders' private values to examine the effect of increased competition on auction performance: We find that increased competition reduced bidder surplus substantially, but less than reduced form estimates would suggest. A significant component of the surplus reduction is due to more aggressive bidding. Counterfactuals establish that as competition increases, concerns regarding auction format play a smaller role.
Private equity fund managers are typically required to invest their own money alongside the fund. We examine how this coinvestment affects the acquisition strategy of leveraged buyout funds. In a simple model, where the investment and capital structure decisions are made simultaneously, we show that a higher coinvestment induces managers to chose less risky firms and use more leverage. We test these predictions in a unique sample of private equity investments in Norway, where the fund manager's taxable wealth is publicly available. Consistent with the model, portfolio company risk decreases and leverage ratios increase with the coinvestment fraction of the manager's wealth. Moreover, funds requiring a relatively high coinvestment tend to spread its capital over a larger number of portfolio firms, consistent with a more conservative investment policy.
This paper describes cash equity markets in Germany and their evolution against the background of technological and regulatory transformation. The development of these secondary markets in the largest economy in Europe is first briefly outlined from a historical perspective. This serves as the basis for the description of the most important trading system for German equities, the Xetra trading system of Deutsche Börse AG. Then, the most important regulatory change for European and German equity markets in the last ten years is illustrated: the introduction of the Markets in Financial Instruments Directive (MiFID) in 2007. Its implications on equity trading in Germany are analyzed against the background of the current status of competition in Europe. Recent developments in European equity markets like the emergence of dark pools and algorithmic / high frequency trading are portrayed, before an outlook on new regulations (MiFID II, MiFIR) that will likely come into force in early 2018 will close the paper.
In the wake of the recent financial crisis, significant regulatory actions have been taken aimed at limiting risks emanating from trading in bank business models. Prominent reform proposals are the Volcker Rule in the U.S., the Vickers Report in the UK, and, based on the Liikanen proposal, the Barnier proposal in the EU. A major element of these reforms is to separate “classical” commercial banking activities from securities trading activities, notably from proprietary trading. While the reforms are at different stages of implementation, there is a strong ongoing discussion on what possible economic consequences are to be expected. The goal of this paper is to look at the alternative approaches of these reform proposals and to assess their likely consequences for bank business models, risk-taking and financial stability. Our conclusions can be summarized as follows: First, the focus on a prohibition of only proprietary trading, as envisaged in the current EU proposal, is inadequate. It does not necessarily reduce risk-taking and it likely crowds out desired trading activities, thereby negatively affecting financial stability. Second, there is potentially a better solution to limit excessive trading risk at banks in terms of potential welfare consequences: Trading separation into legally distinct or ring-fenced entities within the existing banking organizations. This kind of separation limits cross-subsidies between banking and proprietary trading and diminishes contagion risk, while still allowing for synergies across banking, non-proprietary trading and proprietary trading.
An important prerequisite for the efficiency of bail-in as a regulatory tool is that debt holders are able to bear the cost of a bail-in. Examining European banks’ subordinated debt we caution that households may be investors in bail-in able bonds. Since households do not fulfil the aforementioned prerequisite, we argue that European bank supervisors need to ensure that banks’ bail-in bonds are held by sophisticated investors. Existing EU market regulation insufficiently addresses mis-selling of bail-in instruments.
A number of contributions to research on monetary policy have suggested that policy should be asymmetric near the lower bound on nominal interest rates. As inflation and economic activity decline, policy should ease more aggressively than it would in the absence of the lower bound. As activity recovers and inflation picks up, the central bank should act to keep interest rates lower for longer than without the bound. In this note, we investigate to what extent the policy easing implemented by the ECB since summer 2013 mirrors the rate recommendations of a simple policy rule or deviates from it in a way that indicates a “lower for longer” approach to policy near zero interest rates.
Die Studie untersucht die Frage, ob der Gesetzgeber des ARUG die Ziele erreicht hat, die mit der Reform des Rechts der Anfechtung von HVBeschlüssen verfolgt wurden. Darüber hinaus gehend soll die Entwicklung der Beschlußmängelklagen seit der letzten Studie der Verfasser hierzu nachgezeichnet werden. Unsere Studie zeigt, daß seit Inkrafttreten des ARUG ein deutlicher Rückgang der Beschlußmängelklagen und Freigabeverfahren zu verzeichnen ist. Dagegen ist der Anteil der von „Berufsklägern“ erhobenen Klagen und Nebeninterventionen gleich geblieben, wobei sich die Anzahl der Personen in der Gruppe der „Berufskläger“ nochmals vergrößert hat. Das ARUG hat insoweit keine erkennbare Wirkung gehabt...
Schätzwerte mittelfristiger Gleichgewichtszinsen mit der Methode nach Laubach und Williams (2003) werden inzwischen vielfach in der Diskussion um die Geld- und Fiskalpolitik zitiert. Unter anderem wurden sie von Summers (2014a) als Evidenz für eine säkulare Stagnation angeführt und von Yellen (2015) zur Rechtfertigung der Nullzinspolitik verwendet. In diesem Papier nehmen wir eine umfangreiche Untersuchung und Sensitivitätsanalyse dieser Schätzwerte für die Vereinigten Staaten, Deutschland und den Euro-Raum vor. Aufgrund der hohen Unsicherheit und Sensitivität, die mit den Schätzwerten mittelfristiger Gleichgewichtszinsen mit der Laubach-Williams-Methode und ähnlichen Ansätzen verbunden ist, sollten diese Schätzungen nicht den Ausschlag für entscheidende Weichenstellungen in der Geld- und Fiskalpolitik geben.
This paper studies the life cycle consumption-investment-insurance problem of a family. The wage earner faces the risk of a health shock that significantly increases his probability of dying. The family can buy long-term life insurance that can only be revised at significant costs, which makes insurance decisions sticky. Furthermore, a revision is only possible as long as the insured person is healthy. A second important feature of our model is that the labor income of the wage earner is unspanned. We document that the combination of unspanned labor income and the stickiness of insurance decisions reduces the long-term insurance demand significantly. This is because an income shock induces the need to reduce the insurance coverage, since premia become less affordable. Since such a reduction is costly and families anticipate these potential costs, they buy less protection at all ages. In particular, young families stay away from long-term life insurance markets altogether. Our results are robust to adding short-term life insurance, annuities and health insurance.
We consider the continuous-time portfolio optimization problem of an investor with constant relative risk aversion who maximizes expected utility of terminal wealth. The risky asset follows a jump-diffusion model with a diffusion state variable. We propose an approximation method that replaces the jumps by a diffusion and solve the resulting problem analytically. Furthermore, we provide explicit bounds on the true optimal strategy and the relative wealth equivalent loss that do not rely on quantities known only in the true model. We apply our method to a calibrated affine model. Our findings are threefold: Jumps matter more, i.e. our approximation is less accurate, if (i) the expected jump size or (ii) the jump intensity is large. Fixing the average impact of jumps, we find that (iii) rare, but severe jumps matter more than frequent, but small jumps.
Based on a cognitive notion of neo-additive capacities reflecting likelihood insensitivity with respect to survival chances, we construct a Choquet Bayesian learning model over the life-cycle that generates a motivational notion of neo-additive survival beliefs expressing ambiguity attitudes. We embed these neo-additive survival beliefs as decision weights in a Choquet expected utility life-cycle consumption model and calibrate it with data on subjective survival beliefs from the Health and Retirement Study. Our quantitative analysis shows that agents with calibrated neo-additive survival beliefs (i) save less than originally planned, (ii) exhibit undersaving at younger ages, and (iii) hold larger amounts of assets in old age than their rational expectations counterparts who correctly assess their survival chances. Our neo-additive life-cycle model can therefore simultaneously accommodate three important empirical findings on household saving behavior.
This paper investigates the potential implications of say on pay on management remuneration in Germany. We try to shed light on some key aspects by presenting quantitative data that allows us to gauge the pertinent effects of the German natural experiment that originates with the 2009 amendments to the Stock Corporation Act of 1965. In order to do this, we deploy a hand-collected data set for Germany's major firms (i.e. DAX 30), for the years 2006-2012. Rather than focusing exclusively on CEO remuneration we collected data for all members of the management board for the whole period under investigation. We observe that the compensation packages of management board members of Germany's DAX30-firms are quite closely linked to key performance measures. In addition, we find that salaries increase with the size of the company and that ownership concentration has no significant effect on compensation. Also, our findings suggest that the two-tier system seems to matter a lot when it comes to compensation. However, it would be misleading to state that we see no significant impact of the introduction of the German say on pay-regime. Our findings suggest that supervisory boards anticipate shareholder-behavior.
In a production economy with trade in financial markets motivated by the desire to share labor-income risk and to speculate, we show that speculation increases volatility of asset returns and investment growth, increases the equity risk premium, and reduces welfare. Regulatory measures, such as constraints on stock positions, borrowing constraints, and the Tobin tax have similar effects on financial and macroeconomic variables. Borrowing limits and a financial transaction tax improve welfare because they substantially reduce speculative trading without impairing excessively risk-sharing trades.
The old boy network: the impact of professional networks on remuneration in top executive jobs
(2016)
We investigate the impact of social networks on earnings using a dataset of over 20,000 senior executives of European and US firms. The size of an individual's network of influential former colleagues has a large positive association with current remuneration. An individual at the 75th percentile in the distribution of connections could expect to have a salary nearly 20 per cent higher than an otherwise identical individual at the median. We use a placebo technique to show that our estimates reflect the causal impact of connections and not merely unobserved individual characteristics. Networks are more weakly associated with women's remuneration than with men's. This mainly reflects an interaction between unobserved individual characteristics and firm recruitment policies. The kinds of firm that best identify and advance talented women are less likely to give them access to influential networks than are firms that do the same for the most talented men.
The dynamics of entrepreneurial careers in high-tech ventures: experience, education, and exit
(2016)
We investigate the career dynamics of high-tech entrepreneurs by analyzing the exit choice of entrepreneurs: to found another firm, to become dependently employed, or to act as a business angel. Our detailed data resting on the CrunchBase online database indicate that founders stick with entrepreneurship as a serial entrepreneur or as an angel investor only in cases where the founder (1) had experience either in founding other startups or working for a startup, (2) had a ‘jack-of-all-trades’ education, or (3) achieved substantial financial success upon a venture capital exit transaction.
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.
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.
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.
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.
