Robust Gmm Tests for Model Specification, with Applications to Conditional Moments Testing and Structural Instability Testing
نویسندگان
چکیده
Tests for model specification based on the generalized method of moments have been widely used in the literature. Most of the popular tests typically require estimators which are efficient under the hypotheses that models chosen for estimation are correctly specified. This paper develops alternative tests which can be obtained using any consistent estimator. In particular, the test statistics are designed to have the same asymptotic power properties as statistics computed with efficient estimators. Several applications of the alternative testing methods are also considered.

Robust inference with GMM estimators
The local robustness properties of generalized method of moments (GMM) estimators and of a broad class of GMM based tests are investigated in a uni"ed framework. GMM statistics are shown to have bounded in#uence if and only if the function de"ning the orthogonality restrictions imposed on the underlying model is bounded. Since in many applications this function is unbounded, it is useful to hav...
متن کاملRobust GMM tests for structural breaks
We propose a class of new robust Generalized Method of Moments (GMM) tests for endogenous structural breaks. The tests are based on supremum, average and exponential functionals derived from robust GMM estimators with bounded influence function. We study the theoretical local robustness properties of the new tests and show that they imply a uniformly bounded asymptotic sensitivity of size and p...
متن کاملSemi-Parametric Specification Tests for Discrete Probability Models
Loss functions play an important role in analyzing insurance portfolios. A fundamental issue in the study of loss functions involves the selection of probability models for claim frequencies. In this article, we propose a semiparametric approach based on the generalized method of moments (GMM) to solve the specification problems concerning claim frequency distributions. The GMM-based testing pr...
متن کاملEvaluating alternative methods for testing asset pricing models with historical data
We follow the correct Jagannathan and Wang (2002) framework for comparing the estimates and specification tests of the classical Beta and Stochastic Discount Factor/Generalized Method of Moments (SDF/GMM) methods. We extend previous studies by considering not only single but also multifactor models, and by taking into account some of the prescriptions for improving empirical tests suggested by ...
متن کاملGeneralized Spectral Tests for Conditional Mean Models in Time Series with Conditional Heteroscedasticity of Unknown Form
Economic theories in time series contexts usually have implications on and only on the conditional mean dynamics of underlying economic variables. We propose a new class of specification tests for time series conditional mean models, where the dimension of the conditioning information set may be infinite. Both linear and nonlinear conditional mean specifications are covered. The tests can detec...
