Who Are Your Neighbors? The Role of Ideology and Decline of Geographic Proximity in the Diffusion of Policy Innovations
Summary. This study examines how U.S. states adopt policy innovations between 1960 and 2014, analyzing 556 policies to understand what drives adoption decisions. The research finds that ideological similarity between states remains a stable predictor of policy adoption, while geographic proximity to neighboring states has become less influential over time. Political polarization strengthens the role of ideology in shaping which states copy each other's policies.
