To address the challenges posed by global systemically important banks (G-SIBs), the Basel Committee on Banking Supervision recommended an "additional loss absorbency requirement" for these institutions. Along these lines, I develop a microfounded design of capital surcharges that target the...

I study central supervision of local financial regulators in an economic union. Regulators each privately observe benefits from lenient local macroprudential policies. Separate deposit insurance funds allow no discretion to set policies because, with integrated financial markets, regulators...

Modern banking systems are highly interconnected. Despite their various benefits, the linkages that exist between banks carry the risk of contagion. In this paper we investigate how banks decide on direct balance sheet linkages and the implications for contagion risk. In particular, we model a...

We study the functioning and possible breakdown of the interbank market in the presence of counterparty risk. We allow banks to have private information about the risk of their assets. We show how banks’ asset risk affects funding liquidity in the interbank market. Several interbank market...

I argue that systemic bankruptcy of firms can originate from coordination failure in an economy with investment complementarities. This new explanation about the origin of systemic bankruptcy promotes better understanding of how financial fragility arises, and provides theoretical guidance for...

We show that political booms, measured by the rise in governments’ popularity, predict financial crises above and beyond other better-known early warning indicators, such as credit booms. This predictive power, however, only holds in emerging economies. We show that governments in emerging...

By allowing for imperfectly informed markets and the role of private information, we offer newinsights about observed deviations of portfolio concentrations in domestic relative to foreignrisky assets, or “home bias”, from what standard finance models predict. Our model ascribesthe...
