Using a novel geospatial panel combined with data from the 2015 American Community Survey (ACS), we investigate the effect of topography – altitude and terrain unevenness – on income segregation at the neighborhood level. Specifically, we perform large-scale counterfactual simulations by...

Dynamic equilibrium models are specifted to track time series with unit root-like behavior. Thus, unit roots are typically introduced and the optimality conditions adjusted. This step requires tedious algebra and often leads to algebraic mistakes, especially in models with several unit roots. We...

As I document using evidence from a journal data repository that I manage, the datasets used in empirical work are getting larger. When we use very large datasets, it can be dangerous to rely on standard methods for statistical inference. In addition, we need to worry about computational issues....
