Empirical researchers frequently use dynamic panel data models and employ Generalized Method of Moments (GMM) estimators (Hansen, 1982) to estimate model parameters. An important practical problem in the estimation of a dynamic panel data model is the choice of moments as it provides a large number of moment conditions. Even though adding moment conditions leads to efficiency gain according to ...

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, ...

While the classical framework has a rich set of limited information procedures such as GMM and other related methods, the situation is not so in the Bayesian framework. We develop a limited information procedure in the Bayesian framework that does not require the knowledge of the full likelihood. The developed procedure is a Bayesian counterpart of the classical GMM but has advantages over the ...

This paper determines the properties of standard generalized method of moments (GMM) estimators, tests, and confidence sets (CSs) in moment condition models in which some parameters are unidentified or weakly identified in part of the parameter space. The asymptotic distributions of GMM estimators are established under a full range of drifting sequences of true parameters and distributions. The...

t his paper investigates the impact of monetary policies on the exchange rate of selected developing countries during the period 2001-2010. for this purpose, in addition to the theoretical explanation, dynamic panel data based on the generalized method of moments (gmm) have been used to estimate the model. our findings indicate that the lag of exchange rate variable has a positive and signific...

the increase of greenhouse gases (ghg) in which co2 emissions constitute the principal component, is of major environmental problems of all societies. economic growth impels intensive use of resources and as a result, more residues and wastes thrown in the nature that could lead to environmental degradation. this article tries to trace the eventual relationship between trade openness and enviro...
