A Bivariate Causality between Stock Prices and Exchange Rates : Evidence from Recent Asia Flu

This paper applies recently developed unit root and cointegration models to determine the appropriate Granger causality relations between stock prices and exchange rates using recent Asian flu data. Coupled with impulse response functions, it is found that data from Japan and Thailand are in agreement with this approach, so that exchange rates leads stock prices with positive correlation. On the other hand, data of Taiwan suggests the result predicted by the portfolio approach: stock prices lead exchange rates with negative correlation. Data from Indonesia, Korea, Malaysia, and the Philippines indicate strong feedback relations while that of Singapore fails to reveal any recognizable pattern
