The long-run dependence in exchange courses
Abstract
This study provides empirical evidence of the long-run dependence in the returns and volatility of rouble exchange courses. The measures of long-term persistence employed are the modified rescaled range statistics (R/S) proposed by Lo (1991) and the KPSS test. Significant long-run memory is conclusively demonstrated in the volatility measures, while there is a little evidence for the presence of long-run memory in the returns themselves.
