AbstractThe Edgeworth expansion is derived for the GMM distance statistic for a real-valued nonlinear restriction on a normal linear regression. A refinement of the Edgeworth expansion for the Wald statistic (Park and Phillips 1988) is provided. The leading coefficients are shown to be the same in these two expansions. This establishes that, to the order of approximation of the Edgeworth expansion, the GMM distance statistic has a better approximation to the chi-square distribution than does the Wald statistic. The Monte Carlo simulation of Gregory and Veall (1985) is updated to include both heteroskedasticity-robust covariance matrix estimation and the GMM distance statistic. If the robust covariance matrix is calculated under the null, the GMM has near perfect finite sample type I error even in sample sizes as small as 20.
