Diffusion Processes in International Political Economy
This article provides an overview of recent literature on diffusion within the field of International Political Economy (IPE). It considers some of the more significant channels through which diffusion can occur, as well as the major causal processes that are likely to be responsible for the diffusion. After providing a brief overview of the modeling strategy adopted by many of the more influential diffusion studies, it goes on to discuss a number of promising directions for future research. It suggests that the literature has moved away from answering the question of whether diffusion is occurring in different contexts and is now more focused on understanding the conditions under which diffusion is more or less likely to occur. It argues that the study of diffusion within IPE tends to be problem-centered in its approach and stands to benefit from more engagement between quantitative and qualitative research.
