Population age structure and real exchange rates in the OECD

Abstract

Macroeconomic theory predicts that variations in population cohort sizes will lead to demographically induced real exchange rate movements. While such effects have previously been established for individual countries, this paper exploits cross-sectional time series data to test the prediction for a larger number of economies. A reduced form model with population age shares as regressors is estimated using a panel of 25 OECD countries between 1971 and 2002. The results confirm that demographic structure has significant explanatory power for the real exchange rate and the estimated relationship supports age structure effects in accordance with the life cycle hypothesis.
