Purchasing Power Parity is tested for in post-Bretton Woods real exchange rate data from 20 developed countries using univariate tests and covariate augmented versions of the Augmented Dickey-Fuller (CADF) and feasible point optimal (CPT) unit root tests. The covariates are a combination of...

Many countries, both industrialized and developing, appear to have experienced a slowdown in economic growth. We examine a large sample of countries and find that a majority exhibit a significant structural break in their post-war growth rates. In nearly all of these cases the break was followed...

This paper evaluates out-of-sample exchange rate predictability of Taylor rule models, where the central bank sets the interest rate in response to inflation and either the output or the unemployment gap, for the euro/dollar exchange rate with real-time data before, during, and after the...

In light of the substantial movement towards trade liberalization during the postwar period, this paper attempts to determine if, and when, countries experienced statistically significant changes in the paths of their export-GDP and import-GDP ratios. We find that: (1) most trade ratios...

This paper proposes an explicit test for determining the significance and the timing of" slowdowns in economic growth during the postwar period. We examine a large sample of" countries (both industrialized and developing), and find that a majority though not all " exhibit a significant...

This paper investigates the relationship between the new monetary control procedures, implemented by the Federal Reserve Board in October 1979, and the subsequent increase in exchange rate variability for the United States. It shows that, in the context of a stochastic, rational expectations...

Recent literature has documented the sensitivity of unit root tests to failure to account for structural change. This paper reconsiders international evidence on the unit root hypothesis while allowing for two structural breaks. We find evidence of two breaks in three-quarters of the data,...
