This paper tests for purchasing power parity (PPP) using real effective exchange rate data for 90 developed and developing countries in the post-Bretton Woods period. Support for PPP is found, since the majority of countries experience finite deviations of real exchange rates from parity. The...

Univariate studies of the hypothesis of unit roots in real exchange rates have yielded consensus point estimates of the half-life of deviations from purchasing power parity (PPP) of between three to five years (Rogoff, 1996). However, conventional least-squares-based estimates of half-lives are...

There is a common perception that the prices of unrelated commodities move together. This paper re-examines this notion, using a measure of comovement of economic time series called concordance. Concordance measures the proportion of time that the prices of two commodities are concurrently in...

This paper examines the relationship between terms of trade shocks, private saving, and the current account position. The relationship between these variables is theoretically ambiguous: an adverse transitory terms of trade shock can either induce a deterioration or an improvement in the current...

This paper compares the evolution of the Australian current account balance over the period 1954–94 against an optimal current account derived from a consumption-smoothing model. The findings indicate that the Australian current account was not used to smooth consumption optimally in the...

Consensus estimates put the half-life of deviations from purchasing power parity (PPP) at about four years (Rogoff, 1996). However, conventional least squares estimates of half-lives are biased downward. Accordingly, as a preferred measure of the persistence of real exchange rate shocks, this...

This paper investigates empirically the degree of international integration of industrial and emerging country equity markets. It analyzes two issues: first, the extent to which equity prices have tended to move similarly across countries and regions in the long run; and second, the strength of...

This paper examines the duration and magnitude of commodity-price cycles. It finds that for most commodities, price slumps last longer than price booms. How far prices fall in a slump is found to be slightly larger than how far they rebound in a subsequent boom. There is little evidence of a...

Univariate studies of the hypothesis of unit roots in real exchange rates have yielded consensus point estimates of the half-life of deviations from purchasing power parity of between three to five years. However, least squares-based estimates of half-lives are biased downward. Accordingly, we...

This paper examines the optimality of international capital flows to a persistent net importer of capital, Australia, during its post-capital-controls period 1984-98. The results suggest that international capital flows were larger than optimal during the 1980s, but in the 1990s such flows have...
