Generalized Method of Moments and Optimal Instruments

Part A reviews the basic estimation theory of the generalized method of moments (GMM) and Part B deals with optimal instrumental variables. 1 For the most part, we restrict attention to iid observations. Linear Regression Economists often use linear regression to quantify a relationship between economic variables. A linear regression between y and x is a relationship of the form y = x 0 β + ε (...

Generalized Method of Moments

This entry describes the basic framework for statistical estimation and inference using Generalized Method of Moments and also illustrates the types of empirical models in finance to which these techniques have been applied. GeneralizedMethod of Moments (GMM) provides a computationally convenientmethod of obtaining consistent and asymptotically normally distributed estimators of the parameters ...

Optimal bandwidth selection for robust generalized method of moments estimation

A two-step generalized method of moments estimation procedure can be made robust to heteroskedasticity and autocorrelation in the data by using a nonparametric estimator of the optimal weighting matrix. This paper addresses the issue of choosing the corresponding smoothing parameter (or bandwidth) so that the resulting point estimate is optimal in a certain sense. We derive an asymptotically op...

Stochastic Generalized Method of Moments.

The generalized method of moments (GMM) is a very popular estimation and inference procedure based on moment conditions. When likelihood-based methods are difficult to implement, one can often derive various moment conditions and construct the GMM objective function. However, minimization of the objective function in the GMM may be challenging, especially over a large parameter space. Due to th...
