What determines the size distribution of business firms? What kind of firm dynamics may be underlying observed firm size distributions? Which candidate distributions may be used for fitting purposes? We here address these questions from a stochastic model perspective. We construct a firm dynamics process that leads to a Dagum distribution of firm size at equilibrium. An empirical study shows that the proposed model captures the empirical regularities of firm size distributions with considerable accuracy.

Abstract
What determines the size distribution of business firms? What kind of firm dynamics may be underlying observed firm size distributions? Which candidate distributions may be used for fitting purposes? We here address these questions from a stochastic model perspective. We construct a firm dynamics process that leads to a Dagum distribution of firm size at equilibrium. An empirical study shows that the proposed model captures the empirical regularities of firm size distributions with considerable accuracy.
