The article aims to investigate empirically the effects of innovative activities on corporate profitability, using a panel of 267 UK manufacturing firms, over the period 1988-1992. Using the Bayesian approach to, explicitly, consider heterogeneity among firms, we find: (i) a positive and...

Gibrat's law is a referent model of corporate growth dynamics. This paper employs Bayesian panel data methods to test for Gibrat's law and its implications. Using a Pharmaceutical Industry Database (1987-1998), we find evidence against Gibrat's law on average, within or across industries....

In this paper we investigate some properties of the patterns of firms’ growth. Several recent studies about this topic are based on some version of the so-called Gibrat’s Law, which assumes that firms’ growth is erratic. We aimed at testing Gibrat’s Law, as a first step towards a more...

We aim at testing Gibrat's Law, a building block of the corporate growth dynamics. Using a Bayesian statistical framework that nests previous approaches, we provide evidence against Gibrat's law on average, within or across industries. Notwithstanding, data show only weak evidence of mean...
