Abstract: The time series methodology casts some doubt on Sargent-Wallace's joint hypothesis that expectations are rational and the money supply is endogenous. It is to perform an alternative test of whether their model is consistent with the data. The procedure employed is basically to test the cross-equation restrictions imposed by the rationality of expectations. In contrast of the previous findings a key result of this procedure is that it provides empirical support for their joint hypothesis.
