The relative dynamics of investment and the current account in the G7-economies

This paper contributes to the empirics of the intertemporal approach to the current account. We use a cointegrated VAR framework to identify permanent and transitory components of country-specific and global shocks. Our approach allows us to investigate empirically the sensitivity to persistence implied by many forward-looking models and our results shed new light on the excess volatility of investment encountered by Glick and Rogoff (1995). In G7 data, we find the relative current-account and investment response to be in line with the intertemporal approach
