In particular, the estimators may be strongly biased for certain choices of moment conditions. In response to

WebThe idea behind Method of Moments (MoM) estimation is that: to nd a good estimator, we should have the true and sample moments match as best we can. That is, I should choose the parameter such that the rst true moment E[X] is equal to the rst sample moment x. Examples always make things clearer! Example(s) Let’s say x 1;x 2;:::;x WebThe method of simulated moments approach to estimating model parameters is to minimize a certain distance between observed moments and simulated moments with respect to the parameters that generate the simulated model. Denote X our observed data and m ( X) the vector of observed moments.
