Policy Transfer in a European Union: Institutional Isomorphism as a Source of Legitimacy.

This article examines public policy in the European Union (EU) by drawing upon the framework of policy transfer, which has been recently refined by comparativists, and the concept of isomorphism developed within organizational theory. Three case studies--namely, the single currency, tax policy and media ownership policy--are discussed and compared with the aim of assessing the potential of isomorphism for the analysis of policy diffusion. The author argues that European institutions, which have a serious limitation in terms of legitimacy, stimulate policy transfer by catalyzing isomorphic processes. Policy transfer, however, is constrained when there are no national cases to be imitated. Yet European institutions, most notably the European Commission, can overcome the problem by "inseminating" solutions into national political systems. [ABSTRACT FROM AUTHOR]
