Exchange rate fluctuations are regularly monitored with great interest by policy makers, practitioners and academics. It is not surprising, therefore, that exchange rate predictability has long been at the top of the research agenda in international finance. Starting with the seminal contribution of Meese and Rogoff (1983), a large body of empirical research finds that models which condition on economically meaningful variables do not provide reliable exchange rate forecasts. This has lead to the prevailing view that exchange rates follow a random walk and hence are not predictable, especially at short horizons.
Kydland and Prescott (1982) and Prescott (1986) established that productivity shocks could account for most post-World War II business cycle volatility. Business cycle volatility was roughly constant up through the period studied by Kydland and Prescott, but has changed substantially since then. Kim and Nelson (1999), McConnell and Perez-Quiros (2000) and Stock and Watson (2002) all identify a large and statistically significant permanent decline in U.S. GDP volatility beginning in the first quarter of 1984.
