Freeze! Financial Sanctions and Bank Responses
Deutsche Bundesbank Discussion Paper, with Stefan Goldbach and Volker Nitsch
We study the effects of financial sanctions on cross-border credit supply. Using a differences-in-differences approach to analyze eleven sanctions episodes between 2002 and 2015, we find that banks located in Germany reduce their positions in countries with sanctioned entities by 38%. The average German branch or subsidiary outside Germany does not adjust its positions after the imposition of sanctions. For affiliated banks located in countries with low financial standards, we even observe a relative increase in credit supply. These effects are stronger if sanctions are only imposed by EU member states and not by the entire UN.
Bank Bonus Pay as a Risk Sharing Contract
HEC Working Paper, with Harald Hau, Patrick Kampkötter, and Jean-Charles Rochet.
We argue that risk sharing motivates the bank-wide structure of bonus pay. In the presence of financial frictions that make external financing costly, the optimal contract between shareholders and employees involves some degree of risk sharing whereby bonus pay partially absorbs earnings shocks. Using payroll data for 1.26 million employee-years in all functional divisions of Austrian, German, and Swiss banks, we uncover several empirical patterns in bonus pay that are difficult to rationalize with incentive theories of bonus pay—but support an important risk sharing motive. In particular, bonuses respond to performance shocks that are outside the control of employees because they originate in other bank divisions or even outside the bank.
How Do Investors and Firms React to an Unexpected Currency Appreciation Shock?
SFI Working Paper, with Rüdiger Fahlenbrach, Christoph Herpfer, and Philipp Krüger.
We examine the impact of a sudden home currency appreciation on the valuation and behavior of corporations in a developed economy. The Swiss National Bank surprisingly repealed the minimum exchange rate of 1.2 Swiss francs per Euro on January 15, 2015. On that day the franc appreciated by 15% and the main stock market index dropped by 8.7%. The impact was largest for export oriented firms with high domestic costs. These firms experienced 5% lower announcement returns, subsequently faced economically sizeable reductions in sales and profitability, and responded by reducing investment by 8.1% while only slightly reducing employment.
Bank Capital Regulation with an Opportunistic Rating Agency
SFI Working Paper.
(Distinguished CESifo Affiliate Award 2013, Swiss Finance Institute best paper doctoral award 2012)
This paper models the strategic interaction between a rating agency, a bank and a bank regulator who lacks information about bank asset risk. The regulator can either (1) make bank capital requirements contingent on credit ratings; or (2) set rating-independent capital requirements. Truthful ratings provide efficiency gains because they allow the regulator to constrain high risk bank investment without simultaneously reducing overall investment volume. However, if collusion between the rating agency and the bank corrupts rating quality, rating-independent regulation enhances welfare. The welfare benefits are largest if regulators maintain rating-contingent capital requirements and discipline rating agencies.
