WebDownloadable (with restrictions)! In the seminal book “Les Inégalités Économiques,” Gibrat (Les Inégalités Économiques, Librairie du Recueil Sirey, Paris, 2013) proposed the law of proportional effect and claimed that a variety of empirical size distributions—such as income, wealth, firm size, and city size—obey the lognormal distribution. Web1 de abr. de 2009 · [5], [4] is inconsistent with a Gibrat growth process and, second, that the Gibrat process with Laplace growth rates is inconsistent with a Pareto size distribution. These proofs are based on the analysis of the asymptotic behavior of the relevant distributions for large sizes, so they still hold true if one assumes that the previous …

These studies generally observed a lognormal size distribution, that can be explained by a Gibrat process (Gibrat 1931; Hart and Prais 1956; Simon and Bonini 1958).More recently, research has shown …

WebAnother implication of Gibrat's law is that the relative dispersion of the size of firms tends to increase with time. The dispersion of firms that remained in existence over the period increased from 2.89 in 1950/1 to 4.18 in 1959/60. A test was carried out on the bivariate distribution to see if firms regressed towards the mean size.
