In this variant, monetary policy is the only reason for serial correlation in GNP. It is premature, therefore, to conclude, as some authors, have, that the presence of such a root in U.S. GNP is inconsistent with either a stationary natural rate or with nominal shocks playing a major role in the business cycle.
