Conclusions
In this paper, we have tested to what extent and how institutional quality drives productive entrepreneurship that in turn promotes economic growth. With this we obtained improved estimates of the impact of entrepreneurship enhancing institutions on economic growth. To do so, we first augmented the well-established model of Islam (1995) and included various measures of entrepreneurial activity in the panel regressions for a sample of 25 European countries covering 2003–2014. Based on the existing literature on institutions and entrepreneurship, we identified relevant indicators fitting each of the three components identified by Scott (1995): regulative, cognitive, and normative. As for the regulative component, we showed that the regulation of credit, labor, and business is positively—while the size of the government is negatively—related to entrepreneurial activity. Concerning the cognitive element, nurturing a culture of entrepreneurship that stimulates awareness and perceived capabilities was found to be conducive to entrepreneurial activity. And we found a positive link between these institutional variables and GDP per capita growth that operates through all types of entrepreneurial activity. A robustness check, adopting Caselli et al. (1996) proposed econometric technique (GMM-sys) for dealing with panel data structures and one where we also allow the institutional variables under investigation to operate through factor accumulation, corroborate our main findings.
