It is now widely recognized that the most commonly used efficient two-step GMM estimator may have large bias in small samples. This problem has motivated the search for alternative estimators with better finite sample properties. Two classes of alternatives are considered in this paper. The...

This paper contains commentary on the chapter “Simulation and Estimation of Hedonic Models” by Heckman, Matzkin and Nesheim that appeared in the volume "Frontiers in Applied General Equilibrium Modeling," Kehoe, Srinivasan and Whalley (eds.), Cambridge University Press, 2005. I explain in...

We use the Vietnam War draft avoidance behavior documented by Card et Lemieux (2002) as a quasi-natural experiment to infer causation from education to smoking and find strong evidence that education, whether it be measured in years of completed schooling or in educational attainment categories,...

We discuss and illustrate the method of simulation extrapolation for fitting models with additive measurement error. We present this discussion in terms of generalized linear models (GLMs) following the notation defined in Hardin and Carroll (2003). As in Hardin, Schmiediche, and Carroll (2003),...

This paper examines the relationship between adherence to international standards of good practice in policy-making and two key indicators of access to capital markets and the cost of this access: spreads and sovereign ratings. In contrast to other work, this study reviews a broad set of...

International trade is a major channel for technology diffusion. However regressing trade in R&D intensive goods to evaluate the effect of technology imports on productivity in a cross section of countries may be misleading because of simultaneity bias. I identify the effect of technology trade...
