Abstract: | This study uses herefore unavailable daily data on official intervention to test the joint hypotheses of perfect asset substitutability and exchange market efficiency. This joint hypothesis is generally soundly rejected for six exchange rates over various sample periods. In contrast to evidence elsewhere from weekly or monthly data, lagged intervention is a significant determinant of realized profits in about half the cases; this evidence is consistent with existence of a portfolio-balance channel, at least in the short-run. Other evidence indicates that coordinated intervention sometimes may have an impact significantly different from intervention by one central bank alone. |
