Upton examines the U.S. policy process toward the five multilateral development banks-the World Bank Group, the Inter-American Development Bank, the Asian Development Bank, the African Development Bank, and the European Bank for Reconstruction and Development-as a case study in how the United States manages its participation in multilateral institutions. The management of the U.S. role in these institutions is significant primarily because these institutions play an increasingly important role in the U.S. relationship with the developing world and because, for the most part, they are mature institutions being called upon to adapt their roles and operating styles to new financial and political realities. After examining the evolving role of the MDBs from the U.S. perspective, Upon describes the U.S. policy process toward the banks and assesses its strengths and weaknesses. She then sets out recommendations for improving the process and looks at the broader, more general lessons for U.S. policy formulation on multilateral institutions. An important assessment for scholars, researchers, and policy makers involved with international relations and economic policy.
