Centralization and Accountability : Theory and Evidence from the Clean Air Act

This paper studies fiscal federalism when voter information varies across regions. We develop a model of political agency with heterogeneously informed voters. Rent-seeking politicians provide public goods to win the votes of the informed. As a result, rent extraction is lower in regions with higher information. In equilibrium, electoral discipline has decreasing returns. Thus, political centralization reduces aggregate rent extraction. When the central government provides public goods uniformly across space, the model predicts that a region’s benefits from centralization are decreasing in its residents’ information. We test this prediction using panel data on pollutant emissions and newspaper circulation across the United States. The 1970 Clean Air Act centralized environmental policy at the federal level. In line with our theory, we find that centralization induced a faster decrease in pollution in less informed states.(This abstract was borrowed from another version of this item.)
