Although nation-based systems of financial regulation constitute a second-best approach to global welfare maximization, treacherous accountability problems must be acknowledged and resolved before regulatory cooperation can deal fairly and efficiently with cross-border issues. To track and...

This paper argues that the recent Southeast Asian currency crisis was caused by large prospective deficits associated with implicit bailout guarantees to failing banking systems. We articulate this view using a simple dynamic general equilibrium model whose key feature is that a speculative...

There is a new and now extensive literature analyzing government policies for financial stability based on models with endogenous borrowing constraints. These normative analyses often build upon the concept of constrained efficient allocation, where the social planner is constrained by the same...

We study the interplay of optimal ex-ante (macroprudential) and ex-post (monetary or fiscal stimulus) measures to respond to systemic financial crises in a tractable model of fire sales. We find that it is generally optimal to use both, rejecting the Greenspan doctrine to only intervene ex post....
