Freeze! Financial Sanctions and Bank Responses
R&R The Review of Financial Studies, with Stefan Goldbach and Volker Nitsch
(SFS Cavalcade Award 2019 for the Best Paper in CF)
When the UN or another political body impose financial sanctions on a country, banks are typically required to end business relations with targeted counterparties. Based on German regulatory data for years 2002-15, we show that parent institutions of multinational banking groups reduce their positions in sanctioned countries by -38%. However, their branches and subsidiaries in countries with weak policies against financial crime increase lending by +66% after sanctions are imposed. These branches and subsidiaries receive additional intra-group credit from their parent banks. The evidence suggests that credit is rerouted to sanctioned countries through bank branches and subsidiaries in offshore locations.
How Do Investors and Firms React to an Unexpected Currency Appreciation Shock?
R&R The Review of Corporate Finance Studies, with Rüdiger Fahlenbrach, Christoph Herpfer, and Philipp Krüger.
Past research suggests that firms can significantly reduce their exposure to moderate exchange rate fluctuations by means of pass-through and hedging. Studying the appreciation of the Swiss franc by 17 percent on January 15, 2015, we show that firms remain exposed to extreme currency events. Pass-through, a way to share the costs of exchange rate risk with foreign customers, fails after extreme exchange rate shocks, in particular in competitive industries. Firms’ exposure to currency tail risk has real consequences for their investment. The decrease in investment is explained by a reduction in profitable investment opportunities and not by financial constraints.
Bank Bonus Pay as a Risk Sharing Contract
HEC Working Paper, with Harald Hau, Patrick Kampkötter, and Jean-Charles Rochet.
(Best Paper Award at Paris December Finance Meeting 2019)
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 exclusively with incentive theories of bonus pay—but support an important risk sharing motive.
Risk Managers in Banks
HEC Working Paper, with Patrick Kampkötter.
How do banks remunerate risk managers and what are the implications for risk-taking? Studying 127 German banks during the years 2003 to 2007, we show that risk managers’ remuneration is positively aligned with performance-linked pay in front offices (FOs). When bonuses in FOs increase by one Euro, the bonus of a risk manager increases by 13.6 to 33.5 Cents, depending on the risk manager’s seniority. Risk-sharing among employees or labor market competition do not explain this finding. Banks with more aligned incentive pay between risk management and FOs during the years before the crisis of 2008-2009 performed better in the crisis.
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.
