“The Economics of Supranational Bank Supervision" (with Thorsten Beck and Consuelo Silva-Buston)

Abstract: We document large variation in the propensity and the intensity in which countries cooperate in the supervision of banks. We show that these variations can be linked to differences in cooperation gains. Using hand-collected data on supranational agreements for 4,278 country pairs during the period 1995-2013, we find that proxies for bilateral cooperation gains a) increase the likelihood of cooperation, b) accelerate the adoption of cooperation, c) make intense forms of cooperation more likely. An analysis of regional cooperation shows that their make-up, as well as their evolution, is broadly consistent with predicted cooperation gains. Our findings suggests that a uniform approach to supranational supervision is not necessarily desirable as countries differ considerably in the extent to which they benefit from cooperation.

"Slow Bank-Runs and Early Intervention"

Abstract: In the recent Eurozone crisis, slow-motion runs have occurred that started with the slow capital outflow and eventually culminated in bank runs. We analyze the dynamics of such a run. Few sophisticated investors can gather information on the bank’s actual asset value and quickly withdraw their investments in case the bank’s asset value is low. Less informed investors can defer their withdrawal decision to observe the behavior of informed investors and mimic their withdrawal behavior. Waiting avoids inefficient liquidation but leaves late investors with less security. The more investors become informed, the more likely are preemptive panic runs. In these situations of distress, a regulator may prefer early capital injections to later bailouts in order to prevent information acquisition by investors. This may explain repeated capital injections in the European sovereign debt crisis.

"A Theory of Collateral for the Lender of Last Resort"

Abstract: We take a macroprudential approach to analyze the optimal lending policy for the central bank, focusing on externalities that policy imposes on private markets. Lending against high-quality collateral protects central banks against losses but can adversely afect liquidity creation in markets since high-quality collateral gets locked up in the central bank rather than circulating in markets. Lending against low-quality collateral creates counterparty risk but can improve liquidity in markets. We characterize the optimal central bank policy incorporating these trade-offs. We show that, contrary to what is generally accepted, lending against highquality collateral can have negative effects, whereas it may be optimal to lend against lowquality collateral.
