Governments around the world redistribute to distressed areas by conditioning taxes and transfers on location. We show that when poor households are spatially concentrated, transfers from one location to another can yield equity gains that outweigh their efficiency costs, even when income-based...

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...

This paper develops methods for assessing the sensitivity of empirical conclusions regarding conditional distributions to departures from the missing at random (MAR) assumption. We index the degree of non-ignorable selection governing the missingness process by the maximal Kolmogorov-Smirnov...

This paper posits that individuals can more easily form social connections with persons of the same race. If true, the greater the incidence among his neighbors of persons of his race, the more likely an individual is to make neighborhood social capital connections, and the more likely he is to...

Structural econometric methods are often criticized for being sensitive to functional form assumptions. We study parametric estimators of the local average treatment effect (LATE) derived from a widely used class of latent threshold crossing models and show they yield LATE estimates...
