Theoretical and Empirical Issues in the Comparative Measurement of Union Power and Corporatism

What aspects of national trade-union movements systematically affect national policy making and economic performance? While there is general agreement that union density, the proportion of the workforce organized in unions, is an important element of union strength, social scientists are only beginning to identify the other critical elements. That union density is not the whole story can quickly be appreciated by comparing the influence of unions in Britain and Germany. For much of the post-war period, union density has been higher in Britain than Germany, although German unions have sustained at least as important a political and economic role as British unions. An influential theory of group-government relations directed our attention to the degree of hierarchy and monopoly present in an interest structure and to the degree of institutionalized access to policy-making circles, wrapping these characteristics together in the concept of corporatism. Yet there is a developing interest, particularly in the analysis of labour movements, in disaggregating corporatism as part of an effort to understand the specific characteristics that produce political and economic influence.
