This paper investigates the impact of progressive trade openness on the formation of entrepreneurship in a two-country occupation choice model with monopolistic competition. We show that trade opening gives rise to a non-monotonic process of international specialization, in which the share of entrepreneurial firms in the large (small) country first increases (decreases) and then decreases (increases), with the global economy exhibiting first deindustrialization and then reindustrialization.
