While the study of international entrepreneurship has been dominated by studies of international new ventures, the study of comparative international entrepreneurship has received relatively little attention. We argue that since such international differences are often the underlying drivers for entrepreneurship that crosses borders, this area of research has a rich potential to improve our understanding of international entrepreneurship. In this paper, we develop a theoretical framework to examine the effects of the external business environment (the soil) on the entrepreneurial entry by individuals (the seeds). This leads us to fundamental predictions regarding differences in the extent of entrepreneurship in different national contexts. While in developed economies business ventures are more likely to be launched when the turnover rate of incumbent firms is high, the opposite is true in developing economies. Estimates generated using a largescale data set provide empirical support for our theoretical predictions. Our findings suggest important avenues for new research regarding the role of factors such as the liability of newness and the stigma of failure in different national contexts, as well as the manner in which entrepreneurial dynamics evolve over time.Keywords Comparative entrepreneurship Á Corporate instability Á Entry Á Liability of newness Á Stigma of failure JEL Classification L26 Á L22 Á M16
