Empirical Analysis of the Psychological Hypothesis on Exchange Rate Determination and Testing Its Forecastability

Empirical Analysis of the Psychological Hypothesis on Exchange Rate Determination and Testing Its Forecastability: The Korean Experience

The role of psychological impact is examined by investigating the determination of exchange rates, especially the U.S. Dollar. It has been applied to the Korean economic crisis which occurred between January 1997 and June 1999. The basic idea is that psychological information can be used in generating rational expectation, and accourdingly, it would induce exchange market clearance. While psychological hypothesis is weakly supported, results reveal that the U.S. Dollar can be determined by psychological impact. The ex-post simulation process also proves it. The understanding of psychological impact is necessary for the implementation of foreign exchange policies.
