TESTING CONVERGENCE TOWARD GIBRAT’S LAW FOR CZECH MANUFACTURING FIRMS

The paper attempts to examine if there is any convergence toward Gibrat’s law over time for the sample of Czech manufacturing firms over the time period of 2007 – 2015. Firstly, the validity of Gibrat’s law over the entire period from 2007 to 2015 was investigated separately for two samples – for large companies and for small and medium-sized enterprises (SMEs). The validity of Gibrat’s law was tested via the linear regression model with the first-order autoregressive process. While for large firms, there was found no relationship between firm size and firm growth, for the sample of SMEs Gibrat’s law was rejected. Secondly, we tested for both samples if there is any convergence toward Gibrat’s law over time. There is convergence toward Gibrat’s law over time for the sample of SMEs.
