Explaining international differences in entrepreneurship

"We use a micro dataset that collects information across individuals, countries, and time to investigate the determinants of entrepreneurial activity in thirty-seven developed and developing nations. We focus both on individual characteristics and on countries' regulatory differences. We show that individual characteristics, such as gender, age, and status in the workforce are important determinants of entrepreneurship, and we also highlight the relevance of social networks, self-assessed skills, and attitudes toward risk. Moreover, we find that regulation plays a critical role, particularly for those individuals who become entrepreneurs to pursue a business opportunity. The individual characteristics that are impacted most by regulation are those measuring working status, social network, business skills, and attitudes toward risk"--National Bureau of Economic Research web site.
