Abstract

or a well-identified class of forward-looking models under rational expectations and time-varying parameters, it is shown that there exists always a solution having the property of being the closest, in mean square, to the state motion of the autoregressive dynamic equation governing the “ideal” behavior of the economic system. A recursive algorithm—based upon Kalman filtering—providing the exact expression for the conditional expectations (hence, the solution) and the optimal filtering estimate, is also presented.
