Asymmetry in the effects of economic fundamentals on rising and falling exchange rates

Empirical research provides evidence for exchange rates overreaction to changes in economic fundamentals over a short run, but convergence in a long run. In this research we use statistical method developed by Cox [Cox, D.R., “Regression models and life-tables,” Journal of the Royal Statistical Society. Series B (Methodological), Vol. 34, Iss. 2 (1972), 187-220.] to examine the differences in the effects of local economic fundamentals on the probability of occurrence of extreme fluctuations in exchange rates over time periods of rising and falling exchange rates. We identify an extreme fluctuation as a 10% decrease or increase in exchange rate over a three month period and 20% over a one year period. We find asymmetry in the effects of economic fundamentals on exchange rates (eight countries' exchange rates quoted as f/$) during time periods of rising and falling exchange rates: the probability of extreme fluctuation is greater during time periods of rising exchange rates as compared to falling.
