The Validity of Gibrat's Law: Focus on Gender Composition of Top Management

Summary/Abstract: The study is focused on relationship between firm size and firm growth in the context of gender composition of top management of the firms. In accordance with Gibrat´s law, firm growth is the stochastic process that does not depend on firm size. The aim of this study is to find out if the confirmation or rejection of Gibrat´s law validity might be related to the gender composition of management. The data for 20,073 Czech firms in the period 2008 – 2013 is used. To examine the relationship between firm size and firm growth, the linear auto-regression model is applied. The study concludes that the gender composition of top management is not the key factor affecting the validity of Gibrat´s law. The validity of Gibrat´s law is rejected at the aggregate level and also for both men-led and women-led firms. Smaller firms tend to growth faster than their bigger counterparts.
