Discretionary Policy Interactions and the Fiscal Theory of the Price Level: A SVAR Analysis on French Data

We estimate a structural vector autoregressive (SVAR) model of the French economy. The econometric method originates in Blanchard and Perotti [Quarterly Journal of Economics, 2002] but owes also extensively to the fiscal theory of the price level (FTPL) that investigates the interactions between government surplus, debt accumulation and price dynamics. We have the objective, on the one hand, of assessing the effects of fiscal and monetary policy shocks on the economy; and, on the other, of studying the strategic interactions between fiscal and monetary authorities. As a consequence, the theoretical restrictions to identify our model are derived from a FTPL framework. Our estimations reveal so-called Keynesian features of fiscal and monetary shocks; meanwhile, they are consistent with the prediction of the FTPL as regards price dynamics. Although the first part of our findings agree with most of the recent literature on the subject, the non-rejection of the FTPL is an originality.
