In order to examine the impacts of market size on entrepreneurship, we estimate a monopolistic competition model that involves the workers' decisions to pursue entrepreneurship by using data on Japanese prefectures. Our results show that a larger market size in terms of population density leads to a higher incentive for individuals to become entrepreneurs. A 10% increase in the population density increases the share of people who wish to become entrepreneurs by approximately 1%. In contrast, such a positive effect on the self-employment rate is observed only for prefectures with very high or very low densities. The self-employment ratio is negatively associated with population density in prefectures with medium densities.
