We develop a term structure model where the short interest rate and the market price of risks are subject to discrete regime shifts. Empirical evidence from efficient method of moments estimation provides considerable support for the regime shifts model. Standard models, which include affine...

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...

The behavior of quote arrivals and bid-ask spreads is examined for continuously recorded deutsche mark-dollar exchange rate data over time, across locations, and by market participants. A pattern in the intraday spread and intensity of market activity over time is uncovered and related to...

Recent empirical evidence suggests that the interdaily volatility clustering for most speculative returns are best characterized by a slowly mean-reverting fractionally integrated process. Meanwhile, much shorter lived volatility dynamics are typically observed with high frequency intradaily...

Multivariate tests due to Soren Johansen, as implemented by Richard T. Baillie and Tim Bollerslev (1989) and Francis X. Diebold, Javier Gardeazabal, and Kamil Yilmaz (1994), reveal mixed evidence on whether a group of exchange rates are cointegrated. Further analysis of the deviations from the...

This paper provides a detailed characterization of the volatility in the deutsche mark-dollar foreign exchange market using an annual sample of five-minute returns. The approach captures the intraday activity patterns, the macroeconomic announcements, and the volatility persistence (ARCH) known...
