THREE ECONOMETRIC METHODOLOGIES: A CRITICAL APPRAISAL¹

Abstract

Abstract. Three econometric methodologies, associated respectively with David Hendry, Christopher Sims and Edward Leamer have been advocated and practiced by their adherents in recent years. A number of good papers have appeared about each methodology, but little has been written in a comparative vein. This paper is concerned with that task. It provides a statement of the main steps to be followed in using each of the methodologies and comments upon the strengths and weaknesses of each approach. An attempt is made to contrast and compare the techniques used, the information provided, and the questions addressed by each of the methodologies. It is hoped that such a comparison will aid researchers in choosing the best way to examine their particular problem.
