The quantitative and dynamic consequence of a social VAT reform, i.e. a fiscal reform consisting in substituting VAT for social contributions, is assessed using two general equilibrium models. The first one is a Walrasian model with no other frictions than distortionary taxation of labor and...

This paper investigates the characteristics of the Laffer curve in a neoclassical growth model of the US economy with incomplete markets and heterogeneous agents. The shape of the Laffer curve changes depending on which of transfers or government debt are varied to balance the government budget...

Les règles fiscales auto–financées conduisent souvent à une indétermination réelle de l'équilibre macroéconomique, laissant ainsi la place à des fluctuations de type «taches solaires». Dans le cadre d'une économie fermée, la TVA sociale échappe à cette propriété et réduit...

This paper examines issues related to the estimation of the government spending multiplier (GSM) in a Dynamic Stochastic General Equilibrium context. We stress a potential source of bias in the GSM arising from the combination of Edgeworth complementarity/substitutability between private...

Cet article étudie les effets des politiques de désin?ation sur la dynamique macroéconomique américaine. Les politiques de désin?ation sont identifiées à l?aide d?une technique d?épisode comme des chocs réduisant de façon permanente le niveau d?in?ation de long terme. Nous montrons que...

This paper assesses the time series properties of rational expectations models with news shocks. We show that news shocks allows to substantially improve the dynamic behavior of such models in generating higher persistence. We also warn the use of SVAR models to uncover news shocks.

Standard business cycle models face difficulties generating (i) government spending multipliers exceeding unity and (ii) stabilizing effects of government size. Using a simple model with externality in labor supply, we show that a sufficient degree of complementarity between aggregate and...

This article assesses monetary policy’s performances in the Euro zone in the face of supply shocks. We determine the responses of output, inflation, labor share and the nominal interest rate to a supply shock as identified through a structural var model. We then develop a dsge model with...
