Recent studies calling for a more disaggregated approach to the study of the state risk rejecting those conceptual tools such as policy style and state tradition that have been developed for studying macropolitical institutions. Taking as a point of departure Dyson's attempt to relate state traditions and modes of interest-group politics, it is demonstrated that a certain symmetry exists between different types of states and the structures of systems of comprehensive business associations. Specifically, France is shown to have a dualistic system corresponding to its dualist polity, West Germany a system specialized by policy area corresponding to its accommodative polity, and Britain, Canada and the US to have competitive, pluralist systems consistent with their adversarial polities. Such correspondence supports trying to treat as a variable the relationship between macropolitical traditions or policy styles and sectoral policy communities.
