Competition, Risk-Shifting,and Public Bail-out Policies

This paper empirically investigates the effect of government bail-out policies on banks outside the safety net. We construct a measure of bail-out perceptions by using rating information. From there, we construct the market shares of insured competitor banks for any given bank, and analyze the impact of this variable on banks’ risk-taking behavior, using a large sample of banks from OECD countries. Our results suggest that government guarantees strongly increase the risk-taking of competitor banks. In contrast, there is no evidence that public guarantees increase the protected banks’ risk-taking, except for banks that have outright public ownership. These results have important implications for the effects of the recent wave of bank bail-outs on banks’ risk-taking behavior.

Liquidity and Contagion: The Crisis of 1763

The financial crisis that swept across northern Europe in 1763 bears a strong resemblance to more recent episodes of financial distress. The combination of the specific contractual arrange-ments at the time, interlocking credit relationships, and the high leverage of market participants triggered distress sales of assets, leading to a severe liquidity crisis. Hence, the crisis is an early instance of contagion on the asset side of the balance sheet. We highlight the salient features of the 1763 crisis and propose a stylized model of the events. While the financial institutions have changed fundamentally in the intervening 200 or so years, the underlying problems appear to be universal.

Moral Hazard and International Crisis Lending; A Test

We test for the existence of a moral hazard effect attributable to official crisis lending by analyzing the evolution of sovereign bond spreads in emerging markets before and after the Russian crisis. The nonbailout of Russia in August 1998 is interpreted as an event that decreased the perceived probability of future crisis lending to emerging markets. In the presence of moral hazard, such an event should raise not only the level of spreads, but also the sensitivity with which spreads reflect fundamentals as well as their cross-country dispersion. We find strong evidence for all three effects.

Credit Risk Transfer and Bank Competition

We present a banking model with imperfect competition in which borrowers’ access to credit is improved when banks are able to transfer credit risks. However, the market for credit risk transfer (CRT) works smoothly only if the quality of loans is public information. If the quality of loans is private information, banks have an incentive to grant unprofitable loans in order to transfer them to other parties, leading to an increase in aggregate risk. Nevertheless, the introduction of CRT generally increases welfare in our setup. However, under private information, higher competition induces an expansion of loans to unprofitable firms, which in the limit offsets the welfare gains from CRT completely.

Public Ownership of Banks and Economic Growth

In an influential article, La Porta et al. (2002) argue that public ownership of banks is associated with lower GDP growth. We show that this relationship does not hold for all countries, but depends on a countrys initial conditions, in particular its financial development and political institutions. Public ownership is harmful only if a country has low financial development and low institutional quality. The negative impact of public ownership on growth fades quickly as the financial and political system develops. In highly developed countries, we find no or even positive effects. Policy conclusions for individual countries are likely to be misleading if such heterogeneity is ignored.

Why banks are not too big to fail – evidence from the CDS market

This paper argues that bank size is not a satisfactory measure of systemic risk because it neglects aspects such as interconnectedness, correlation, and the economic context. In order to differentiate the effect of bank size from that of systemic importance, we control for systemic risk using the CoVaR measure introduced by Adrian and Brunnermeier (2011). We show that a banks contribution to systemic risk has a significant negative effect on banks’ credit default swap (CDS) spreads, supporting the too‐systemic‐to‐fail hypothesis. Once we control for systemic risk, bank size (relative to gross domestic product (GDP)) has either no or a positive effect on banks’ CDS spreads. The effect of bank size increases in the home countrys debt ratio and turns positive already at moderate debt ratios. This result is consistent with the too‐big‐to‐save hypothesis. We show further that the effect of systemic risk rises sharply at the onset of the financial crisis in August 2007, but weakens after the failure of Lehman Brothers, reflecting changing bailout expectations. Taken together, our results suggest that banks are not too big to fail, but they may be too systemic to fail and too big to save.

The Threat of Capital Drain: A Rationale for Public Banks?

This paper yields a rationale for why subsidized public banks may be desirable from a regional perspective in a financially integrated economy. We present a model with credit rationing and heterogeneous regions in which public banks prevent a capital drain from poorer to richer regions by subsidizing local depositors, for example, through a public guarantee. Under some conditions, cooperative banks can perform the same function without any subsidization; however, they may be crowded out by public banks. We also discuss the impact of the political structure on the emergence of public banks in a political-economy setting and the role of interregional mobility.

Public Ownership of Banks and Economic Growth – The Role of Heterogeneity

In an influential paper, La Porta, Lopez-De-Silanes and Shleifer (2002) argued that public ownership of banks is associated with lower GDP growth. We show that this relationship does not hold for all countries, but depends on a country’s financial development and political institutions. Public ownership is harmful only if a country has low financial development and low institutional quality. The negative impact of public ownership on growth fades quickly as the financial and political system develops. In highly developed countries, we find no or even positive effects. Policy conclusions for individual countries are likely to be misleading if such heterogeneity is ignored.

The Threat of Capital Drain: A Rationale for Regional Public Banks?

This paper yields a rationale for why subsidized public banks may increase regional welfare in a financially integrated economy. We present a model with credit rationing and heterogeneous regions in which public banks prevent a capital drain from poorer to richer regions by subsidizing local depositors, for example, through public guarantees. Under some conditions, cooperative banks can perform the same function without any subsidies; however, they may be crowded out by public banks. We also discuss the influence of the political structure on the emergence of public banks in simple political-economy settings and the role of interregional mobility.

Family and gender still matter: the heterogeneity of returns to education in Germany

Using information on family background, we estimate returns to education, allowing for the heterogeneity of returns. In order to control for the unobserved heterogeneity shared by family members, we construct a siblings sample and employ family fixed-effects and family correlated random-effects models. Our main result is that family background still matters despite the substantial political efforts to equalize educational opportunities in Germany. Persons with less-educated parents earn lower wages, but have higher returns to education. This supports the view that persons from less-educated backgrounds still face higher marginal costs in the educational system. The same interplay between the wage level and marginal returns is found for the effect of gender and cohort.
