Researchers who study the incidence and performance of organizations empirically know well the value of public policy in providing, in some contexts, sources of exogenous variation that can help with identification. This identification strategy fundamentally is predicated on the fact that differences or changes in public policy often have important consequences for organizational form decisions as well as the performance of different forms of organizations. This talk, however, emphasizes the reverse relationship, namely the important role that organizational economics can and should play in informing public policy debates. It does so by highlighting two important competition policy areas where I believe that further research using the lens of organizational economics would be especially valuable in guiding the development, application and enforcement of specific approaches and policies.
