following the classical approach based on I(0) stationarity or I(1) cointegrating relationships, we use fractional integration/cointegration … three variables are I(1). But we only find cointegration in the presence of autocorrelated disturbances, which means that … opposed to classical cointegration, which implies long memory and slow reversion to equilibrium. This suggests that an …
