Abstract
This note considers testing overidentifying restrictions with incorrect weights in a generalized method of moments framework. It is shown that the test statistic under a fairly general class of non-optimal weighting matrices can be decomposed asymptotically into the sum of a chi-squared random variable and an additional quadratic form. The decomposition is used to find the distribution of the statistic.
