We investigate the expectations hypotheses of the term structure of interest rates and of the foreign exchange market using vector autoregressive methods for U.S. dollar, Deutsche mark, and British pound interest rates and exchange rates. We examine Wald, Lagrange multiplier, and distance metric tests by iterating on approximate solutions that require only matrix inversions. Bias-corrected, con...

Although they refer to currently fashionable ‘candidate genes’ – e.g. dysbindin, neuregulin and DISC1 – it appears that they do not regard these as established. I agree that there is no consistency in the findings across even the largest genome scans conducted to date (samp...
