Integration of Long-Term Interest Rates: Empirical Evidence for G7 Countries

This article investigates the fractional cointegration relationship between long-term interest rates of G7 countries over the period from 1990: 01 to 2010: 04 by estimating the cointegrating regressions for possible bivariate, trivariate and four-variate subsystems as well as the full system. The obtained results indicate that long-term interest rates are fractionally cointegrated for bivariate subsystems of Canada-France, Canada-Japan and Canada-UK and four-variate subsystem of Canada-USA-France-UK, implying integration.
