We explore the impact of rising incomes at the top of the distribution on spatial sorting patterns within large U.S. cities. We develop and quantify a spatial model of a city with heterogeneous agents and non-homothetic preferences for neighborhoods with endogenous amenity quality. As the rich...

We study trends in income inequality across U.S. states and counties 1960-2019 using a mix of administrative and survey data sources. Both states and counties have diverged in terms of per-capita pre-tax incomes since the late 1990s, with transfers serving to dampen this divergence. County...

We study optimal spatial policies in quantitative trade and geography frameworks with spillovers and sorting of heterogeneous workers. We characterize the spatial transfers that must hold in efficient allocations, as well as labor subsidies that would implement them. Assuming homogeneous workers...

How do political preferences shape transportation policy? We study this question in the context of California's High-Speed Rail (CHSR). Combining geographic data on votes in a referendum on the CHSR with a model of its expected economic benefits, we estimate the weight of economic and...
