The literature on currency crisis has generally not answered to the following question: which economic policies may reduce the contagion effects of a speculative shock? We use a dynamic Mundell-Fleming model extended to four countries and compute three time-consistent equilibria: a Nash...

This paper deals with Euro introduction and ask whether it is likely to increase the exchange rates volatility on a world-wide scale. Following this purpose, we present a three country-model (US, Germany and France) and compare the exchange rate volatility according to the nature of the shock...

The paper first reviews the evolution of federal fiscal rules in the United States, showing a trend towards balanced-budget rules, not golden rules. An explanation to this trend is provided in a model that includes voter's preferences that are skewed by the history of the budget structure, and...

This article studies the impact of oil shocks on the macroeconomy in two ways insofar unexploited in the literature. The analysis is conducted at the global level, and it explicitly accounts for the potentially changing nature of oil shocks. Based on an original world GDP series and a grouping...

We estimate a SVAR model of the French economy. The econometric method originates in Blanchard and Perotti [Quarterly Journal of Economics, 2002] but owes also extensively to the fiscal theory of the price level (FTPL) that investigates the interactions between government surplus, debt...

This paper addresses the issue of whether and by how much public investment or public capital can enhance economic performance. In comparison with the literature on the subject, we apply many different methodologies to answer these questions. A VAR model (for France, Italy, Germany, the UK and...

We reconsider the link between domestic public debts and average and domestic inflation rates in a monetary union, using a modified version of a model by Beetsma and Vermeylen (2002). It is thus possible to show that the causation between the inflation dynamics and the public finances might go...

Des économistes ont cru déceler dans l'économie danoise le paradigme des " contractions budgétaires expansionnistes ". L'intérêt pour le Danemark était alors dû à la simultanéité de trois phénomènes entre les années 1982 et 1986 : une reprise économique forte, une rigueur...

This paper uses the SVAR methodology to investigate the effects of public investment on growth, and more specifically, the effects of the introduction of a golden rule of public finance. We extend the existing literature by estimating a model of the British economy that takes into account long...
