4.The literature on (neo)corporatism is vast, and definitions are not always uniform. However, most approaches converge on a concept of neocorporatism as a mode of interest group structuration and policy formulation in which (1) union and business associations tend to be monopolistic and quite centralized and (2) wage and other policies are formulated in peak-level tripartite concertation between the state and social actors, largely bypassing legislative institutions and territorial representation. The presence of prolabor or labor-based parties in government was often seen as increasing the likelihood of neocorporatist arrangements since labor would get state rewards for its cooperation. State corporatism was distinguished from the Northern European type of societal corporatism or neocorporatism. Whereas in Northern Europe, societal corporatism developed from unions and their affiliated parties and was more compatible with labor autonomy and democracy, in Latin America and Southern Europe, state corporatism was the product of state initiative and resulted in substantial regulation and control of unions if occasionally in their empowerment. Seminal works are Philippe Schmitter, “Interest Intermediation and Regime Governability in Contemporary Western Europe and North America,” in S. Berger, ed., Organizing Interests in Western Europe (Cambridge, UK: Cambridge University Press, 1982); Peter Lange and Geoffrey Garrett, “The Politics of Growth,” The Journal of Politics 47, no. 3 (1986): 792—827; and Ruth Berins Collier and David Collier, “Inducements Versus Constraints: Disaggregating `Corporatism,'” American Political Science Review 73, no. 4 (1979): 967—86; on the distinction between state and societal corporatism and the different dimensions of the concept, see David Collier, “Trajectory of a Concept: `Corporatism' in the Study of Latin American Politics,” in P. Smith, ed., Latin America in Comparative Perspective (Boulder: Westview Press, 1994). Necoporatism, in particular confederate-level wage bargaining, has been increasingly challenged by economic internationalization; yet an abundant literature, including the current debate on “varieties of capitalism” points out the resilience (and even the resurgence) of sectorally coordinated wage-bargaining and social pacts in various parts of Europe since the late 1990s; see, for example, Mario Regini, “Between Deregulation and Social Pacts: The Responses of European Economies to Globalization,” Politics and Society 28, no. 1 (2000): 5—33; and Martin Rhodes and Oscar Molina, “Corporatism: Past, Present and Future of a Concept,” Annual Review of Political Science 5, (2002): 305—31. For a more recent revision of the trajectory of the concept and practice, see “The Study of Organized Interests: Before `The Century' and After” in C. Crouch and W. Streeck, eds. The Diversity of Democracy (Cheltenham: Edward Elgar, 2006).
