Public Policy and Foreign Policy: Divergences,Intersections, Exchange

Policy studies tend to be divided between domestic matters and foreign affairs. Scholars seldom employ one another's literature, and they largely draw on different traditions within political science. This article explores the potential for cross‐fertilization and calls for greater integration of these related subfields. The argument considers the case for unity, parallelism, and overlap between domestic public policy studies and foreign policy studies. It examines the reasons for the divide and surveys a variety of attempts to find solutions for the problem of intersection at the boundary between national life and the international environment. It places the dichotomy in a broader context of political science as a whole and offers suggestions about potentially fruitful exchanges. It treats globalization and suggests that a theory of the state could be helpful to both tendencies in policy studies.
