Exploiting Locally Exogeneous Variation in Spatial Data: Linear Regression with Many Small Units

Abstract

This article shows how researchers can exploit \textit{locally exogeneous variation} even in the presence of endogeneity, autocorrelation, or spurious correlation. It describes the infill asymptotic properties of generalized least squares estimation with county-level data, Census tract-level data, and similar regional averages, including sufficient conditions for consistency, asymptotic normality, and valid inference.
