The Zero-Information-Limit Condition and Spurious Inference

Startz, Richard; Nelson, Charles R. - Econometric Society - 2004

The fact that weak instruments lead to spurious inference is now widely recognized. In this paper we ask whether spurious inference occurs more generally in weakly identified models. To distinguish between models where spurious inference will occur from those where it does not, we introduce the...

Efficient Semiparametric Estimation of Quantile Treatment Effects

Firpo, Sergio - Econometric Society - 2004

This paper presents calculations of semiparametric efficiency bounds for quantile treatment effects parameters when selection to treatment is based on observable characteristics. The paper also presents three estimation procedures for these parameters, all of which have two steps: a...

Treatment Effect Heterogeneity in Theory and Practice

Angrist, Joshua - Econometric Society - 2004

Instrumental Variables (IV) methods identify internally valid causal effects for individuals whose treatment status is manipulable by the instrument at hand. Inference for other populations inevitably requires some sort of homogeneity assumption. I develop a simple theoretical framework that...

Some Results on the Asymptotic Normality of k-Class Estimators in the Case of Many Weak Instruments

Swanson, Norman R.; Chao, John C. - Econometric Society - 2004

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...

Tax Interdependence in American States

Agostini, Claudio - Econometric Society - 2004

State governments finance their expenditures with multiple tax instruments, so when collections from one source decline, they are typically compensated by greater revenues from other sources. This paper addresses the important question of the extent to which personal and corporate income taxes...

Quasi Empirical Likelihood Estimation of Moment Condition Models

Sherlund, Shane M. - Econometric Society - 2004

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...

Parametric and Semi-parametric Estimations of the Return to Schooling in South Africa

Bhalotra, Sonia; Sanhueza, Claudia - Econometric Society - 2004

This paper estimates return to schooling for african and coloured women in South Africa. It compares parametric and semiparametric estimates of the sample selection model for the case of return to schooling. The parametric estimator is the one proposed by Heckman (1979) and the semiparametric...

Agent Heterogeneity and Learning: An Application to Labor Markets

Woodcock, Simon D. - Econometric Society - 2004

I develop a matching model with heterogeneous workers, firms, and worker-firm matches, and apply it to longitudinal … unemployed. Firms vary in their marginal product and cost of maintaining a vacancy. The marginal product of a worker-firm match … depends on worker and firm marginal productivities, as well as a match-specific interaction between worker and firm that I …
