This paper presents results from a Monte Carlo study concerning inference with spatially dependent data. We investigate the impact of location/distance measurement errors upon the accuracy of parametric and nonparametric estimators of asymptotic variances. Nonparametric estimators are quite...

This paper examines whether spillovers from local market human capital are important in explaining the distribution of productivity across Malaysia. We develop an empirical method for describing local human capital distributions based on the idea that spillovers are limited in scope by costs of...

In this paper we develop new estimation methods for identifying causal effects based on the idea that the amount of selection on the observed explanatory variables in a model provides a guide to the amount of selection on the unobservables. Our approach involves the use of factor model as a way...
