This collection of seminal readings in international political economy charts the historical and theoretical evolution of the field from the eighteenth century to the present day. Bringing together classic works and leading contemporary arguments, this book outlines the development of three schools of IPE thought -- Liberalism, Marxism, and Realism -- and also includes recent syntheses of these approaches to show how conventional theoretical categories are giving way to more eclectic conceptual schemes. The second edition features an added section on the postmodern turn in the study of international political economy, and includes a number of new readings. The readings include works by Alexander Hamilton, Friedrich List, David Ricardo, Adam Smith, Lenin, Karl Marx, Friedrich Engels, Richard Cooper, Robert O. Keohane, Joseph S. Nye, Christopher Chase-Dunn, Robert Cox, Robert Gilpin, Mancur Olson, Richard Zeckhauser, Bruno S. Frey, Immanuel Wallerstein, Susan Strange, Donald J. Puchala, Raymond F. Hopkins, Alice A. Amsden, Peter M. Haas, David Harvey, and Michael J. Shapiro. Providing many of the most frequently cited IPE references in a single volume, the second edition of The Theoretical Evolution of International Political Economy will no doubt be a valuable resource for students of international relations and international economics.
