The article attempts to explain the expansion of the European Community (EC) policy agenda to new policy areas such as the environment, regional development and research and technological development, and the variations in policy development from one area to another. Lowi's classification of policy types-regulatory, redistributive and distributive-is adapted for use in the EC context. Each policy type, it is argued, deals with a distinct arena featuring different actors, different institutional decision rules, and different types of Council bargaining, and each therefore corresponds to a distinctive pattern of task expansion. Thus, regulatory policies can be explained in terms of functional spillover from the Internal Market, while redistributive policies can be understood as side-payments in larger intergovernmental bargains, and distributive policies are the result of the Commission's policy entrepreneurship and log-rolling Council bargaining. These three patterns of task expansion are examined in an empirical study of policy development across six areas.

A central question in the welfare state debate has been whether or not social policies in industrialized countries converge. Originally linked to the logic of industrialism perspective, this idea has been criticized by researchers focusing on differences in timing and differences in the institutional set up of social security schemes across countries. Nonetheless, I argue that social security arrangements in European as well as Anglo-American countries may gradually become more similar. Using pension politics as the primary example, the article locates similar social and political mechanisms at work in different countries, pushing toward convergence in policy outcomes, despite persistent variation in institutional arrangements. In the final section of the article, I extract a model from the analysis, aimed at explaining political change while maintaining a connection between the micro and macro level of analysis.

The Advocacy Coalition Framework (ACF) was developed to provide a causal theory of the policy process which would serve as one of several alternatives to the familiar stages heuristic, with its recognized limitations. This paper first summarizes the central features of the ACF, including a set of underlying assumptions and specific hypotheses. We next review the implications for the framework of six case studies by various authors dealing with Canadian education and with American transportation, telecommunications, water, environmental, and energy policy. While generally supportive of the ACF, the case studies also suggest several revisions.

A policy-focused human capital approach to development, incorporating industrial policy but stressing land reform, education, and labor-intensive production, is used to explain why South Korea and Taiwan have developed more successfully since 1960 than Argentina, Brazil, or Mexico. The policy-focused human capital approach is contrasted to free-market and cultural-values approaches.
