France has a track record of persistent general government deficits, partly reflecting pro-cyclical fiscal policies in upswings. This has resulted in a quadrupling of its public debt-to-GDP ratio since the 1970s to above 80% of GDP. Reducing public debt is crucial because a high level of public...

The recent fears of a sovereign debt crisis have spurred interest in the sustainability of public debt. There are two different approaches to the assessment of sustainability: the use of sustainability gap indicators (Blanchard et al., 1990) and the time series approach (Trehan and Walsh, 1988)....

We study the dynamic Ramsey problem of finding optimal public debt and linear taxes on capital and labor income within a tractable infinite horizon model with incomplete markets. With zero public expenditure and debt, it is optimal to tax the risky labor income and subsidize capital, while a...

This paper analyses the dynamic effects of fiscal imbalances in a given EMU member state on the borrowing costs of other countries in the euro area. The estimation of a multivariate, multi-country time series model (specifically a Global VAR, or GVAR) using quarterly data for the EMU period...

We consider an economy where competing political parties alternate in office. Due to rent-seeking motives, incumbents have an incentive to set public expenditures above the socially optimum level. Parties cannot commit to future policies, but they can forge a political compromise where each...

The aim of this paper is to analyze the sustainability of public debt in Italy during the last 150 years (1861-2010) by employing a database containing several statistical novelties: new time series estimates of public debt and GDP (respectively Bank of Italy and Baffigi, 2011) and an original...

We assess the sustainability of public finances in the EU15 using stationarity and cointegration analysis. Specifically, we use panel unit root tests of the first and second generation allowing in some cases for structural breaks. We also apply modern panel cointegration techniques developed by...

This paper analyses optimal income taxes over the business cycle under a balanced-budget restriction, for low, middle and high income households. A model incorporating capital-skill complementarity in production and differential access to capital and labour markets is de-veloped to capture the...

Large and growing levels of public debt in the United States, United Kingdom, Japan and the Euro Area raise new interest in the cross-country effects of a large open economy’s deficits. We consider a dynamic optimising model with costly tax collection and exogenously given public spending and...
