We develop a tractable framework to study the optimal design of stress scenarios. A principal wants to manage the unknown risk exposures of a set of agents. She asks the agents to report their losses under hypothetical scenarios before mandating actions to mitigate the exposures. We show how to...

We study time-consistent bank resolution mechanisms. When interventions are ex post efficient, a government cannot commit not to inject capital into the banking system. Contrary to common wisdom, we show that the government may still avoid moral hazard and implement the first best allocation by...

In countries where wages are primarily set by collective bargaining, the effects on unemployment of changes in the economic environment depend crucially on the speed of learning of unions. This speed of learning is likely to depend in turn on the quality of the dialogue that unions have with...

Until the 1990's, US markets were more competitive than European markets. Today, European markets have lower concentration, lower excess profits, and lower regulatory barriers to entry. We document this surprising outcome and propose an explanation using a model of political support. Politicians...

We provide a first evaluation of the quality of banking stress tests in the European Union. We use stress tests scenarios and banks' estimated losses to recover bank level exposures to macroeconomic factors. Once macro outcomes are realized, we predict banks' losses and compare them to actual...
