Peter Boettke of George Mason University and author of Challenging Institutional Analysis and Development: The Bloomington School (co-authored with Paul Dragos Aligica), talks with EconTalk host Russ Roberts about the Bloomington School--the political economy of Elinor Ostrom (2009 Nobel Laureate in Economics), Vincent Ostrom, and their students and colleagues at Indiana University. The discussion begins with the empirical approach of Elinor Ostrom and others who have studied the myriad of ways that actual communities have avoided the tragedy of commons. Boettke emphasizes the distinction between privatization vs. informal norms and cultural rules that prevent overuse. The conversation also looks at urban development and the benefits and costs of multiple municipalities vs. a single, large city. Throughout, Boettke embeds the conversation in the Ostroms' interest in how the citizenry can be self-governing and the challenges of implementing local knowledge.
