' The Twenty Years' Crisis (New York: Harper & Row, 1964), 235-36. First published by Macmillan (London), 1939. ' Informed by problems of world order and grounded in earlier studies of international law and organization, studies of international regimes are beginning to proliferate. The first important study was Robert O. Keohane and Joseph S. Nye, Power and Interdependence (Boston: Little, Brown, 1977). See also Ernst B. Haas, "Why Collaborate? Issue-Linkage and International Regimes," World Politics 32 (April 1980), 357-405, and Oran R. Young, "International Regimes: Problems of Concept Formation," World Politics 32 (April 1980), 331-56. A recent attempt to define and illustrate the regime concept more carefully can be found in Stephen D. Krasner, ed., "International Regimes," a special issue of International Organization 36 (Spring 1982). Scholars are also beginning to use the regime concept in empirical analyses of specific international issues. See, for example, Raymond F. Hopkins and Donald J. Puchala, eds., The Global Political Economy of Food (Madison: University of Wisconsin Press, 1979), and George Quester, ed., "Nuclear Proliferation: Breaking the Chain," a special issue of International Organization 35 (Winter 1981). 3See Charles P. Kindleberger, The World in Depression, 7929-/9^9 (Berkeley: University of California Press, 1974); Robert Gilpin, U.S. Power and the Multinational Corporation (New York: Basic Books, 1975); and Robert O.
