This paper examines several specification errors in the M2-based P* model and develops an M1-based estimate of this model. The apparent statistical significance of M2 is shown to arise from a spurious regression that uses a non-stationary regressor and because the significance test for M2 is...

In the P-star model the price level is determined by the money stock per unit of potential output and the long-run equilibrium level of the velocity of money. This article applies this model to Austria. Problems in identifying permanent shocks to potential output and/or velocity lead to the...
