Working Paper
Stress tests and information disclosure
Superseded by Working Paper 15-10. We study an optimal disclosure policy of a regulator who has information about banks? ability to overcome future liquidity shocks. We focus on the following trade-off: Disclosing some information may be necessary to prevent a market breakdown, but disclosing too much information destroys risk-sharing opportunities (Hirshleifer effect). We find that during normal times, no disclosure is optimal, but during bad times, partial disclosure is optimal. We characterize the optimal form of this partial disclosure. We also relate our results to the debate on the ...
Working Paper
Market-based regulation and the informational content of prices
Various laws and policy proposals call for regulators to make use of the information reflected in market prices. We focus on a leading example of such a proposal, namely that bank supervision should make use of the market prices of traded bank securities. We study the theoretical underpinnings of this proposal in light of a key problem: if the regulator uses market prices, prices adjust to reflect this use and potentially become less revealing. We show that the feasibility of this proposal depends critically on the information gap between the market and the regulator. Thus, there is a strong ...

Enhancing prudential standards in financial regulations
The financial crisis has generated fundamental reforms in the financial regulatory system in the U.S. and internationally. Much of this reform was in direct response to the weaknesses revealed in the precrisis system. The new ?macroprudential? approach to financial regulations focuses on risks arising in financial markets broadly, as well as the potential impact on the financial system that may arise from financial distress at systemically important financial institutions. Systemic risk is the key factor in financial stability, but our current understanding of systemic risk is rather limited. ...

Stress tests and information disclosure
Supersedes Working Paper 13-26 . We study an optimal disclosure policy of a regulator that has information about banks? ability to overcome future liquidity shocks. We focus on the following tradeoff: Disclosing some information may be necessary to prevent a market breakdown, but disclosing too much information destroys risk-sharing opportunities (the Hirshleifer effect). We find that during normal times, no disclosure is optimal, but during bad times, partial disclosure is optimal. We characterize the optimal form of this partial disclosure. We relate our results to the Bayesian persuasion ...
Working Paper
Stress Tests and Information Disclosure
We study an optimal disclosure policy of a regulator that has information about banks (e.g., from conducting stress tests). In our model, disclosure can destroy risk-sharing opportunities for banks (the Hirshleifer effect). Yet, in some cases, some level of disclosure is necessary for risk sharing to occur. We provide conditions under which optimal disclosure takes a simple form (e.g., full disclosure, no disclosure, or a cutoff rule). We also show that, in some cases, optimal disclosure takes a more complicated form (e.g., multiple cutoffs or nonmonotone rules), which we characterize. We ...

The Interplay Among Financial Regulations, Resilience, and Growth
Interconnectedness has been an important source of market failures, leading to the recent financial crisis. Large financial institutions tend to have similar exposures and thus exert externalities on each other through various mechanisms. Regulators have responded by putting more regulations in place with many layers of regulatory complexity, leading to ambiguity and market manipulation. Mispricing risk in complex models and arbitrage opportunities through regulatory loopholes have provided incentives for certain activities to become more concentrated in regulated entities and for other ...
