Understanding the processes of firm growth - a closer look at serial growth rate correlation

Serial correlation in annual growth rates carries a lot of information on growth processes - it allows us to directly observe firm performance as well as to test hypotheses. Using a 7-year balanced panel of 10 000 French manufacturing firms, we observe that small firms typically are subject to negative correlation of growth rates, whereas larger firms display positive correlation. Furthermore, we find that those small firms that experience extreme positive or negative growth in any one year are unlikely to repeat this performance in the following year.
