He is the founding, General Editor of the Cambridge University Press Series on Business and Public Policy and the co-editor of the Journal of Policy Analysis and Management. Professor Prakash's research examines core issues in the study of governance: how do institutions emerge, how they diffuse and get adopted, and how they impact outcomes. In doing so, he studies the complex relationship of businesses with governments and non-governmental organizations. His recent work focuses on the emergence, recruitment/diffusion, and efficacy of voluntary programs in the for-profit as well as the non-profit sectors. He is also examining issues pertaining to (1) NGO advocacy, (2) Corporate Responsibility, and (3) the influence of trade and FDI networks on the cross-country diffusion of rules, standards, and norms in areas such as the environment, human rights, labor rights, property rights and women's rights.

'When do firms choose to follow voluntary environmental standards? Why do they apparently seek less freedom to pollute? Using the theory of green clubs and evidence from ISO 14001, Prakash and Potoski help resolve these policy mysteries. The Voluntary Environmentalists should interest readers concerned with finding innovative ways to improve environmental performance.' James T. Hamilton, Duke University
