Data and Code for: Heterogeneous Workers and Federal Income Taxes in a Spatial Equilibrium

We study the geographic incidence and efficiency of an income tax by estimating a spatial equilibrium model with heterogeneous workers. The US income tax shifts households out of high-productivity cities, leading to locational inefficiency of 0.28% of output. Removing spatial tax distortions increases inequality because more educated households are more mobile and own larger shares of land. Flattening the tax schedule, or introducing cost-of-living adjustments or local wage adjustments leads to efficiency gains but causes substantial increases in inequality. Differences in mobility and land ownership across skill groups create an equity-efficiency trade-off that is unique to spatial settings.
