Nigeria has been depending on oil as its major export commodity for decades leading to the neglect of other vital economic resources. This situation led to massive unemployment as a result of an undiversified economic system, which in turn created an alarming paucity of external accruals to...

This paper reports new evidence of a time-varying risk premium, and against the usual interpretation of irrationality, in survey data for three major currency markets. Using the cointegrated VAR to better focus on the issue of persistence, the deviations from Uncovered Interest Parity are found...

This paper develops a wavelet (spectral) approach to estimate the parameters of a linear regression model where the regressand and the regressors are persistent processes and contain a measurement error. We propose a wavelet filtering approach which does not require instruments and yields...

Using genetic programming techniques to find technical trading rules, we find strong evidence of economically significant out-of-sample excess returns to those rules for each of six exchange rates, over the period 1981-1995. Further, when the dollar/deutschemark rules are allowed to determine...

This article investigates a trading strategy that relies on private information in an electronic spot foreign exchange market. In a structural microstructure model extended for high-frequency data, our analysis links the informational content of trading activity to order size. We find that large...

This paper develops a wavelet (spectral) approach to test the presence of a unit root in a stochastic process. The wavelet approach is appealing, since it is based directly on the different behavior of the spectra of a unit root process and that of a short memory stationary process. By...

Differences in real interest rates across developed economies are puzzlingly large and persistent. I propose a simple explanation: Bonds issued in the currencies of larger economies are expensive because they insure against shocks that affect a larger fraction of the world economy. I show that...

L’approche multifractale en finance a fait dernierement l’objet de developpements theoriques que l’on doit principalement a Calvet et Fisher (2001, 2002). Dans cet article, nous presentons la modelisation multifractale (Multifractal Model of Asset Returns, MMAR) dont nous proposons une...

Output fluctuations in nontraded sectors are a primary country-specific risk factor because nontraded outputs are consumed domestically. While nontraded sector growth risks are mostly non-diversifiable, they can be partially mitigated by international trades in other sectors. The mitigation...
