This paper provides conditions for identification and estimation of the conditional or unconditional average effect of a binary treatment or policy on a scalar outcome in models where treatment may be misclassified. Misclassification probabilities and the true probability of treatment are also...

This paper proposes shrinkage methods in instrumental variable estimations to solve the ``many instruments'' problem. Even though using a large number of instruments reduces the asymptotic variances of the estimators, it has been observed both in theoretical works and in practice that in finite...

This paper analyzes conditions under which various k-class estimators are asymptotically normal in a simultaneous equations framework with many weak instruments. In particular, our paper extends the many instruments asymptotic normality results obtained by Morimune (1983), Bekker (1994), Angrist...

In this paper, I develop a quasi empirical likelihood estimator that has good finite-sample properties when there are many moment conditions. I show that the quasi empirical likelihood estimator, which uses semiparametric efficient estimation, is an approximation to the empirical likelihood...

This paper estimates returns to education using US data. Using the NLS and NLSY79 (dataset) average wages for workers with different ability and educational levels can be estimated. Because of the high correlation between schooling and ability it is not possible to estimate across the entire...

We analyze the importance of information about individual skills for understanding economic growth and income inequality. The paper uses the framework of an OLG economy with endogenous investment in human capital. Agents in each generation differ by random individual ability, or talent, which...

In this paper, we match firm data to individual work history files in order to simultaneously estimate the wage and employment duration processes of a longitudinal sample of two million French workers employed in roughly one million firms and followed over twenty years. The particular structure...
