From an iron triangle to an iron duet?

Abstract

Abstract. The paper addresses five constructs of policy making: policy curtain, iron triangle, issue network, policy community and an iron duet. The five constructs are distinguished on the basis of two variables: exclusion, denoting the degree of openness to new participants, and interdependence, pertaining to relationship between participants. A policy curtain prevails in the pre‐agenda stage denoting both exclusion and lack of dependence. Iron triangle is characterized by exclusion and interdependence; issue network portrays inclusion and lack of interdependence; a policy community features inclusion and interdependence. A fifth construct — an iron duet combines characteristics of an iron triangle, an issue network and a policy community. The paper suggests that the five constructs of policy making are not only products of political environment but are affected by distribution of resources and primacy of values within a specific issue‐area. It further argues that a sequential development may take place following alterations in the division of power between state agencies and organized groups. The involvement of powerful groups of professionals in a policy community, produced by mutual dependence of state and association, may lead to formation of a policy (iron) duet. The historical evolution of specialization entitlement in Israeli health policy serves as a case study to illustrate the major arguments of the paper.
