I am heading to the LSE for a conference on Freedom and Economic Development. Other presenters include Joseph Stiglitz, Andrei Shleifer, Daron Acemoglu, Anne Krueger, Robin Burgess and Tim Besley. Pete Leeson and I are delivering a paper titled "Two Tiered Entrepreneurship and Economic Development" and the basic point made in the paper is that there is positive relationship between entrepreneurship and economic development provided the rules of the game are such that they encourage productive entrepreneurship (arbitrage and innovation), but there is also entrepreneurship over the rules of the game to minimize the opportunities for predation by private and public actors. The form of entrepreneurship over the rules governing social interaction has been overlooked to a considerable degree --- especially the private mechanisms of enforcement in underdeveloped economies that emerge in the small-scale trading behavior of individuals. The paper by Pete and I build on the great work of P.T. Bauer, who is being honored at this meeting.
