Much of the debate about development in the past decade pitted proponents of unfettered markets against advocates of developmental states. Yet, in many developing countries what best explains variations in economic performance is not markets or states but rather the character of relations between business and government. The studies in Business and the State in Developing Countries identify a range of close, collaborative relations between bureaucrats and capitalists that enhance elements of economic performance and defy conventional expectations that such relations lead ineluctably to rent-seeking, corruption, and collusion. All based on extensive field research, the essays contrast collaborative and collusive relations in a wide range of developing countries, mostly in Latin America and Asia, and isolate the conditions under which collaboration is most likely to emerge and survive. The contributors highlight the crucial roles played by capable bureaucracies and strong business associations.
