Abstract
The efficient instruments for Method of Moments estimation of nonlinear models are often of unknown or intractable functional form. Existing semiparametric results on this are geared to situations either of random sampling or limited forms of time dependence. This paper considers a popular empirical example from the econometrics time series literature to illustrate that a substantial efficiency gain is possible using a semiparametric approach.
