We develop a three stage game model composed of a regulator and two firms. These firms compete on the same market where they offer the same homogeneous good, and can invest in R&D to lower their emission/output ratio. By means of a tax per-unit of pollution and a subsidy per-unit of R&D level,...

We propose an overlapping generations economy where households care about relative consumption, the difference between their consumption and the consumption of their reference group. An individual's consumption is driven by the comparison of his lifetime income and the lifetime income of his...

This paper considers recycling in a general equilibrium model. It is shown that recycling should be subsidized if recycling costs are high, as an incentive to recycle all of the available waste. This tax incentive should vanish if recycling is profitable enough. In this case, recycling should...

Économie très largement ouverte, intégrée, située au centre de l’Europe, la France entre en concurrence directe avec ses voisins aussi bien en termes de marchés qu’en termes d’attractivité. Il lui est impossible aujourd’hui de réfléchir à son système fiscal sans prendre en...

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...
