The Journal of Finance

The Journal of Finance publishes leading research across all the major fields of finance. It is one of the most widely cited journals in academic finance, and in all of economics. Each of the six issues per year reaches over 8,000 academics, finance professionals, libraries, and government and financial institutions around the world. The journal is the official publication of The American Finance Association, the premier academic organization devoted to the study and promotion of knowledge about financial economics.

Common Stochastic Trends in a System of Exchange Rates

Published: 03/01/1989   |   DOI: 10.1111/j.1540-6261.1989.tb02410.x

RICHARD T. BAILLIE, TIM BOLLERSLEV

Univariate tests reveal strong evidence for the presence of a unit root in the univariate time‐series representation for seven daily spot and forward exchange rate series. Furthermore, all seven spot and forward rates appear to be cointegrated; that is, the forward premiums are stationary, and one common unit root, or stochastic trend, is detectable in the multivariate time‐series models for the seven spot and forward rates, respectively. This is consistent with the hypothesis that the seven exchange rates possess one long‐run relationship and that the disequilibrium error around that relationship partly accounts for subsequent movements in the exchange rates.


Cointegration, Fractional Cointegration, and Exchange Rate Dynamics

Published: 06/01/1994   |   DOI: 10.1111/j.1540-6261.1994.tb05161.x

RICHARD T. BAILLIE, TIM BOLLERSLEV

Multivariate tests due to Johansen (1988, 1991) as implemented by Baillie and Bollerslev (1989a) and Diebold, Gardeazabal, and Yilmaz (1994) reveal mixed evidence on whether a group of exchange rates are cointegrated. Further analysis of the deviations from the cointegrating relationship suggests that it possesses long memory and may possibly be well described as a fractionally integrated process. Hence, the influence of shocks to the equilibrium exchange rates may only vanish at very long horizons.
