THE EFFECTS OF FISCAL SHOCKS ON CONSUMPTION: RECONCILING THEORY AND DATA*

In: The Manchester School, Band 75, Heft 2, S. 193-209

Abstract

Recent research has stressed the inconsistency between empirical evidence and the theoretical prediction of both the standard real business cycle and the New Keynesian models regarding the impact of fiscal shocks on consumption. Some authors have attempted to bridge this gap by relying on assumptions about the effects of government spending on preferences and production, or on deviations from the intertemporal optimizing framework. In this paper we follow a different route. We show that introducing at the same time imperfect competition, sticky prices and deviations from Ricardian equivalence through an overlapping generations model helps to solve the inconsistency between theory and data. Our paper can also be seen in the light of the classic controversy between Keynesians and monetarists on the effectiveness of fiscal policy. From this angle, our model can be considered a reincarnation of the classic work of Blinder and Solow (Journal of Public Economics, Vol. 2 (1973), pp. 319–337).
