摘要
An immediate implication of cointegration is the existence of Granger-causal orderings among cointegrated series. This implies that asset prices determined in a weakly efficient market cannot be cointegrated. This proposition is tested using daily data for 18 foreign currencies. Tests are conducted for both pairwise combinations of currencies and higher-order systems. No significant evidence of cointegration among exchange rates is found. © 1990.
