This paper deals with public good provision and rent-seeking in an economy consisting of two regions with different preferences over public good consumption. The government either provides a national public good or two regional public goods with spillover effects. Since public expenditures are financed by general taxation, individuals in both regions try to influence policy-making in their preferred direction. Interesting results emerge from the analysis and in particular: rent seeking or influence activities for a national public good are increasing in the degree of heterogeneity across regions and there are also increasing in the degree of spillovers of local public goods.
