Abstract
Administrative reform has been a very common activity of governments in almost all industrialised democracies, including those in Western Europe. The frequent contacts among these governments, and the presence of organisations such as the OECD that are spreading the reforms, might be expected to produce widespread diffusion of administrative innovations. That diffusion is not, however, as widespread as might have been expected and there are marked differences among countries as well as among types of reform. Using Boolean algebra, this article analyses the correlates of the diffusion of reform among European countries and the implications of that diffusion for public administration in these countries.
