WebJun 17, 2015 · In the case of exactly identified models, he suggests setting the fnscale to a small number to force the optim minimizer to converge closer to 0. Also, he thinks the BFGS algorithm works better with GMM. summary (gmm (g, x, t0=rep (0,2), method = "BFGS", control=list (fnscale=1e-8))) Both solutions work for this example. Thanks Pierre!
