The paper characterizes the optimal tax scheme in an open economy with structural inefficiencies on the labor market and on government size. On analytical grounds first, we show that the economy can use fiscal revaluation to exploit the terms of trade externality and to dampen the impact of an...

Most European countries suffer from a structural weakness of employment and competitiveness. Can an optimal tax system reinforce European countries in this respect? If so, does this long-term policy act as a devaluation or a revaluation? In this paper, we show that fiscal devaluation can be an...

We provide a first attempt to include o?-balance sheet, implicit insurance to SIFIs into a consistent assessment of fiscal sustainability, for 27 countries of the European Union. We first calculate tax gaps a la Blanchard (1990) and Blanchard et al. (1990). We then introduce two alternative...

The unprecedented tax hikes implemented in Greece in 2010 generated a much lower than expected increase in tax revenues. In this paper, we document a new stylized fact explaining this gap: the strong increase of tax evasion. We then analyze the response of the economy to tax hikes in a stylized...

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...

In this paper we assess the impact of commodity price volatility on tax revenues, while existing works were concentrated on its effect on economic growth. Our empirical analysis is carried out on 80 developing countries over 1980-2008. We compute country-specific indices which measure the...

In this paper, we assess the impact of fiscal consolidation on income inequality. Using a panel of 18 industrialized countries from 1978 to 2009, we find that income inequality significantly rises during periods of fiscal consolidation. In addition, while fiscal policy that is driven by spending...

This paper studies the local dynamic properties of a simple general equilibrium model with Social VAT. Strict balanced budget rules often lead to real indeterminacy of aggregate equilibrium, leaving room for «sunspots» fluctuations. In a closed-economy setup, social VAT escapes this property...

This article analyses the impact of the electoral calendar on the composition of tax revenue (direct versus indirect taxes). It thus represents an extension of traditional political budget-cycle analyses assessing the impact of elections on overall revenue. Panel data from 56 developing...

This paper shows that government debt creates a so far neglected wealth effect that has sizable effects on business cycle fluctuations. We present a new channel through which governments can influence cyclical fluctuations generated by any type of shock and contribute to macroeconomic stability....
