Use of Spectral Analytic Techniques in Economics.

摘要

In recent years spectral analysis has become an increasingly popular tool for use in the estimation of econometric models. The interest in spectral analysis stems largely from the desire to have additional methodologies for estimating economic time series relationships when the more traditional time-domain methods are not satisfactory. However, there has been relatively little discussion on the advisability of using spectral analysis for such purposes. In this paper the author comments upon the applicability of spectral analysis to econometric problems and provides some guidelines as to when spectral analysis may prove a useful tool for economists.
