Abstract

Firm-size distributions for the one hundred largesr UK firms in 1981, 1975 and 1971 are analysed using simple and piecewise regression techniques. The concavity observed for the Pareto plots in each case, it is argued, relate to existence of contiguous classes in each data set. Our results lend support to the theoretical approach to firm-size distributions based on Gibrat's weakened distribution. A study of the size classes estimated shows that the hirerarchical structure of the largest UK firms has altered radically over a ten year timescale.
