We argue that social capital places strong constraints on an entrepreneur’s ability to found a firm in a region in which he or she does not have connections. We examine this thesis using comprehensive data on the Danish population and find evidence broadly consistent with this claim. Entrepreneurs tend to open businesses in regions in which they have deep roots (”home” regions). We further find that their ventures perform better (survive longer) when they locate in these home regions. The value of social capital moreover appears substantial, similar in magnitude to the value of having prior experience in the industry entered (i.e. human capital).

This paper explores the firm growth rate distribution in a Gibrat’s Law context. The aim is to provide an empirical exploration of the determinants of firm growth. The work is novel in two respects. First, rather than limiting the analysis to focus on the conditional mean growth level, we investigate the complete shape of the distribution. Second, we show that the differences in the firm growth rate process between large and small firms are highly circumstantial. That industry dynamics have a substantial influence on the relationship between firm size and firm growth. The data used includes more than 9000 Danish firms from manufacturing, services and construction. We provide robust evidence indicating that firm growth studies should be less obsessed with explaining means and instead look to other parts of the firm growth rate distribution.

Using Danish firm data covering almost 9000 observations, we find significant proof that firm growth cannot be considered as a simple Gibrat growth process. Key variables, such as size, age, geographical location and industry structure are tested against firm growth rates in turnover and employment. Besides running the regressions on all observations, we also consider and find highly interesting patterns in an industry context. Thus, we conclude that firm growth cannot be considered idiosyncratic. Firm growth is highly dependent on industry and geography.
