Since the term structure of interest rates embodies information about future economic activity, we extract relative Nelson-Siegel (1987) factors from cross-country yield curve differences to proxy expected movements in future exchange rate fundamentals. Using monthly data for the United Kingdom,...

Standard estimates of the NAIRU or natural rate of unemployment are subject to considerable uncertainty. We show in this paper that using multiple indicators to extract an estimated NAIRU cuts in half uncertainty as measured by variance and gives a 33% reduction in the confidence band. The...

The life cycle/permanent income hypothesis suggests that optimization by consumers should cause marginal utility to approximate a random walk. As a consequence, purchases of nondurable goods should also approximately follow a random walk and purchases of durable goods should approximately follow...

We estimate a multivariate ARFIMA model to illustrate a cointegration testing methodology based on joint estimates of the fractional orders of integration of a cointegrating vector and its parent series. Previous cointegration tests relied on a two-step testing procedure and maintained the...
