- Abstract
- Shocks to a bank’s ability to raise liquidity at short notice can trigger depositor panics. Why don’t banks take a more active role in managing these risks? We study contingent risk management (hedging) in a standard global-games model of a bank run. Banks fail to hedge precisely when the exposure to a shock is most severe, just when risk management would have the biggest impact. Higher bank capital and broader deposit-insurance coverage crowd out hedging by banks that already manage risk, yet encourage more banks to establish risk management desks in the first place. The model also yields testable implications for hedging incentives and policy design.

- Abstract
- Bank market power, both in the loan and deposit market, has important implications for credit provision and for financial stability. This article discusses these issues through the lens of a simple theoretical framework. On the asset side, banks choose the quality and quantity of loans. On the liability side, they may be subject to depositor runs whenever they offer demandable contracts. Thisstructure allows us to review the literature on the role of market power for credit provision and stability and also highlight the interactions between the two sides of banks’ balance sheets. Our approach identifies relevant channels that deserve further analysis, especially given the rising importance of bank market power for monetary policy transmission and the rise of the digital economy.

- Abstract
- Loan guarantees represent a form of government intervention to support bank lending. However, their use raises concerns as to their effect on bank risk-taking incentives. In a model of •nancial fragility that incorporates bank capital and a bank incentive problem, we show that loan guarantees reduce depositor runs and improve bank underwriting standards, except for the most poorly capitalized banks. We highlight a novel feedback effect between banks•' underwriting choices and depositors' •run decisions, and show that the effect of loan guarantees on banks' incentives is different from that of other types of guarantees, such as deposit insurance.
