Abstract
This article challenges the traditional view of French industry—that small, inefficient family firms retarded France's economic growth—by examining data for the French textile and flour milling industries taken from the industry census of 1861–1865. The evidence suggests that the average size of French firms suited the economic and technological conditions of the day. The industries studied exhibit constant returns to scale over a wide output range. France would not seem likely to have gained much from larger firms. This is consistent with revisionist contentions that French industry was as rational as that of other nations.
