Empirical Approaches to Fiscal Policy Modelling

Alberto Heimler and Daniele Meulders In the last decade the modelling of the interrelationship between public finance and the rest of the economy has seen substantial advances, reflected in many of the papers delivered to the Applied Econometrics Association Conference held at Confindustria, Rome, on 30 November and 1 December 1989. In particular, the development of the literature on applied general-equilibrium modelling has found most of its applications in the field of taxation, enlarging and completing the estimation of the welfare loss due to distortionary taxes. In this context an important extension has been the introduction of overlapping-generation models. Furthermore, it has become clear that most individual decisions, especially the decision whether or not to work, are dependent upon the tax system, in the sense that the higher the marginal income tax the larger the wedge between labour cost and take-home pay, the last one being the decision variable in the demand for leisure. Finally, in the European context, the completion of the internal market has brought about the necessity to harmonize fiscal systems in the EEC member countries. A number of papers study, therefore, the effects of fiscal reform on efficiency, welfare and growth.
