Reallocation and Learning Over the Business Cycle.

I show how cyclical aggregate shocks can stimulate structural reallocation activities, which in turn amplify the effect of the shock. I emphasize the informational aspects related to restructuring activities and their potential interplay with aggregate shocks. Building on work by Caplin and Leahy (1994), I develop a model in which production units are uncertain about the value of staying in the market and learn about it over time in a Bayesian fashion. In addition to their own private assessment, they can also learn from observing other units' decisions.
