GMM with many weak moment conditions
Using many moment conditions can improve efficiency but makes the usual GMM inferences inaccurate. Two step GMM is biased. Generalized empirical likelihood (GEL) has smaller bias but the usual standard errors are too small in instrumental variable settings. In this paper we give a new variance estimator for GEL that addresses this problem. It is consistent under the usual asymptotics and under ...
متن کاملGmm with Many Moment Conditions By
1 This paper provides a first order asymptotic theory for generalized method of moments (GMM) estimators when the number of moment conditions is allowed to increase with the sample size and the moment conditions may be weak. Examples in which these asymptotics are relevant include instrumental variable (IV) estimation with many (possibly weak or uninformed) instruments and some panel data model...
متن کاملAdaptive Elastic Net GMM Estimator with Many Invalid Moment Conditions: A Simultaneous Model and Moment Selection
This paper develops an adaptive elastic-net GMM estimator with many possibly invalid moment conditions. We allow for the number of structural parameters (p0) as well as the number of moment conditions increasing with the sample size (n). The new estimator conducts simultaneous model and moment selection. We estimate the structural parameters along with parameters associated with the invalid mom...
متن کاملAdaptive Elastic Net GMM Estima- tion with Many Invalid Moment Conditions: Simultaneous Model and Moment Selection CENTER FOR POLICY RESEARCH –Spring 2015
This paper develops the adaptive elastic net GMM estimator in large dimensional models with many possibly invalid moment conditions, where both the number of structural parameters and the number of moment conditions may increase with the sample size. The basic idea is to conduct the standard GMM estimation combined with two penalty terms: the quadratic regularization and the adaptively weighted...
متن کاملTesting for Identication in GMM under Conditional Moment Restrictions
This paper proposes a simple test for global identi cation of Generalized Method of Moments (GMM) estimators in models de ned by conditional moment restrictions. The test is based on comparing two estimators, one which is always consistent, even under global identi cation failure of the unconditional model, and the GMM estimator. It is shown that the test is able to detect Pitman alternatives, ...
