Diffusion processes in IGO networks: The case of democracy

In this paper, I examine the network of intergovernmental organizations, or IGOs, and its impact on the diffusion of democracy around the world. I propose that IGOs facilitate this diffusion by transmitting information between their member states and by interpreting that information according to the prevailing norms in the world society, where democracy is viewed as the legitimate form of government. In my empirical analysis, I find that democracy does diffuse through IGO networks, and that the influence of democratic countries is stronger than that of undemocratic countries, providing support for the role of IGOs as facilitators of communication and interpreters of information. I conclude with a discussion of future research directions and practical implications of this research.
