Network Effects in Policy Diffusion: Evidence from U.S. State Legislatures

Dear Dr. Kim, Thank you for your patience. The reviewer sees promise in the network design but asks for a major revision before we can continue. Please add a temporal robustness check, report the block-model diagnostics, and clarify how the paper separates geographic spillovers from shared partisan control. We would be glad to consider a revised manuscript with a point-by-point response. Best regards, The Editors

Dear Editors, Please find attached the revised manuscript. We have carefully addressed all reviewer comments. In particular, we have added a robustness check using a temporal exponential random graph model and clarified the partisan-homophily result with event-history regressions. Sincerely, Daniel Kim
