In a federation, local policies with inter-regional spillovers depend on the extent and the nature of local capture. Local lobbyists who have multi-regional scope internalize inter-jurisdictional externalities to a larger extent than the lobbyists with interests in a single region. In particular, multi-regional industrial groups lobby for lower interregional trade barriers than local industrial lobbies. The results are based on a simple model, case-study evidence, and econometric analysis of micro-level panel data from Russia. Controlling for firm-level fixed effects, the performance of firms increases with an increase in the number of neighboring regions captured by multiregional groups. The paper has implications for international trade: lobbying by multinationals should lead to lower protectionism compared to lobbying by national corporations.
