In this paper, we argue that institutions affect the allocation of entrepreneurship across new and established organizations. This is confirmed by empirical analysis of the Global Entrepreneurship Monitor (GEM) data on early-stage (independent) entrepreneurial activity and entrepreneurial employee behavior. Most comparative international research on entrepreneurship has focused on independent new ventures and has ignored the pursuit of entrepreneurial opportunities within established organizations (intrapreneurship). However, in developed economies the prevalence of entrepreneurial employee behavior is on average found to be in the same order of magnitude as that of independent entrepreneurial activity. At the same time prevalence rates of these two types of entrepreneurship vary substantially between countries. We analyze the allocation of entrepreneurial activity across early-stage independent entrepreneurial activity (entrepreneurship in new organizations) and entrepreneurial employee activity (entrepreneurship in established organizations) in 36 countries, taking into account effects of the level of economic development as well as the formal and informal institutional setting. We find that labor market institutions and the extent to which societies value autonomy affect the allocation of entrepreneurship across new and established organizations.
