Diffusion of regulatory impact analysis among OECD and EU member states

With the exception of few comparative case studies, the literature on regulatory reform and regulatory impact analysis (RIA) tends to focus on internal political actors, activities, and processes. Furthermore, empirical analyses of new public management have overlooked the dynamics of communications among networks of administrative reformers. This article fills these gaps, presenting results of an event history analysis on the diffusion of RIA. It probes rationales for the origin of RIA and administrative capacity explanations in combination with variables referring to international and transnational communication channels of administrative reforms. A hypothesis based on legal origin is also tested. The findings show that the decision to adopt RIA rests on transnational networks as well as administrative variables such as government expenditure and legal origin
