The mean variance efficiency (MVE) of a portfolio of international bonds and equities is tested using a CAPM model of excess returns. The conditional variances and covariances of the portfolio returns are allowed to time-vary according to shocks in up to three global macro-economic variables...

In this paper we extend the research on the predictability of stock and bond markets to futures markets. By using stock and bond market forecasting variables we build ex ante models of the MATIF CAC 40 and DFB DAX stock index futures contracts. Since it is possible to construct a practical...
