Assessing convergence to purchasing power parity: A panel study for ten OECD countries
Tóm tắt
Assessing Convergence to Purchasing Power Parity: A Panel Study for 10 OECD Countries. — The paper analyzes whether post-Bretton Woods real exchange rates of ten OECD countries are nonstationary so that long-run purchasing power parity (PPP) can be considered to hold. A test procedure is proposed which treats the various real exchange rates as a panel but still allows to assess the rate of convergence to PPP for each pair of currencies separately. It is shown that long-run (tradables-) PPP holds between all countries analyzed. Rates of convergence to PPP, however, are found to be quite different across countries. For most of the OECD countries convergence takes place faster than previously indicated.
