Quantitative implications of the fiscal theory of the price level

The traditional interpretation of effect of money on prices provided by the Quantity Theory of Money (QTM) has been challenged reciently by the Fiscal Theory of the Price Level (FTP). This paper analyzes the QTM and the FTP from different angle and provides quantitative results of the alternative interpretations. The analysis is based on a general equilibrium rational expectations model driven by monetary, fiscal, and productivity shocks. If the money supply relationship is the determinant of the price level we obtein the standard effects of shocks. However, if the goverment budget constraint is the relation that determines inflation, the impulse response function to the shocks are different. These results are a reference to evaluate the relevance of alternative monetary models: the quantitative implications of a fiscal theory and a a quantitative theory are not the same.
