The Impact of Business Cycle Conditions on Firm Dynamics and Composition.

This paper estimates the causal impact of short-term aggregate fluctuations in Egypt, 1911–48, using global cotton price shocks. Firm entry was procyclical, and exit was acyclical. There were persistent differences between cohorts over the cycle; expansionary cohorts were of lower quality. The evidence supports models of firm entry with ex-ante heterogeneity. The findings highlight the extensive margin of entry as the primary adjustment mechanism. As a result, recessions had a strong "isolation" effect. This nature of firm entry amplified and propagated temporary price shocks. [ABSTRACT FROM AUTHOR]
