The authors extend Daniel McFadden's (1989) method of simulated moments to approximating efficient estimators in general estimation problems. The general approach applies a simulated bias correction to an approximation of the efficient score. They discuss a general trade-off in estimator inefficiency between bias correction and moment approximation. Copyright 1994 by MIT Press.
