On the Evolution of the Firm Size Distribution: Facts and Theory

Luis Cabral and José Mata

No 3045, CEPR Discussion Papers from Centre for Economic Policy Research

Abstract: Using a comprehensive data set of Portuguese manufacturing firms, we show that the firm size distribution is significantly right-skewed, evolving over time toward a log-normal distribution. We also show that selection accounts for very little of this evolution. Instead, we propose a simple theory based on financing constraint. A calibrated version of our model does a good job at explaining the evolution of the firm size distribution.
