This paper studies local governments' public policies in a metropolitan area plagued by traffic congestion, where both residents and workers consume local public goods. We develop a new spatial sub-metropolitan tax competition model which features a central city surrounded by suburban towns linked by mobile capital and mobile residents who commute to work. We show that Pareto-efficiency is...

This paper proposes an identification strategy that makes use of a multi-tier federal system. State-level fiscal reforms provide an arguably exogenous source of variation in tax rates of local jurisdictions. Moreover, state borders spatially bound the effects of state-level...
