The output multiplier turns negative before a deficit spending program expires.We show the generality of this unpleasant finding for the standard real business cyclemodel. We then calibrate an extended model for the US and demonstrate how fiscalstimulus slows down economic recovery from...

This paper develops a comprehensive endogenous growth framework to determinethe optimal mix of growth policies. The analysis is novel in that we captureimportant elements of the tax-transfer system and fully take into account transitionaldynamics in our numerical analysis. Currently, for...

Previous research on optimal R&D subsidies has focussed on the long run.This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method.Starting from the steady state under current R&D subsidization in the...

When a deficit occurs in the funding of collective goods, it is usually covered by raising theamount of taxes or by rationing the supply of the goods. This article compares the efficiencyof these institutions. We report the results of a 2x2 experiment based on a game in the firststage of which...

We use a stylized model to show that, if transfers to the poor arefounded on a security argument, there is a negative trade-off betweenlaw enforcement expenditures and criminality. In contrast, if transfersare based on altruism, the correlation between the same variables mayappear positive. We...

By using official time series of the Italian evaded VAT base (Ministry of Finance) for the period 1980-2004 we investigate empirically the long-run characteristics of tax evasion and the relationship with the tax burden. We focus on three important issues not analyzed so far[...]
