Market Size and Entrepreneurship

Abstract

In order to examine the impacts of market size on entrepreneurship, we estimate a monopolistic competition model that involves entrepreneurial decision by using data on Japanese prefectures. Our results show that a larger market size measured by the population density leads to higher incentive of people to become entrepreneurs. a 10 percent increase in the population density increases the share of people who wish to become entrepreneurs by 2 percent. In contrast, the self-employment ratio is lower in prefectures with higher population density, which suggests that the market size has different impacts on the entrepreneurship in different stages.market size, entrepreneurship, density economies, market expansion
