Chocs budgétaires et dynamique économique en Tunisie sous une approche de type VAR Structurel

To evaluate the effectiveness of fiscal policy in Tunisia, we use the SVAR approach based on the work of Blanchard and Perotti (2002). Our paper shows the short-term macroeconomic efficiency of a structural increase in budgetary expenditure in Tunisia with a budget multiplier close to 2.7%, in line with the Keynesians models. However, the estimated effect of a structural increase in tax revenues on activity is non-Keynesian (increase in the level of economic activity). This is explained by the presence of the voracity effect in the case of the Tunisian economy. Thus, a structural shock in tax revenues leads to a rapid and immediate adjustment of budgetary expenditure, which neutralizes the recessionary effect of the tax increase on economic activity in Tunisia.
