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.

Data from Indonesia, Korea, Malaysia, and the Philippines indicate strong feedback relations while that of Singapore fails to reveal any recognizable patter
