This paper analyses a growth model wherein saving results from bequestas-consumption. It first looks at the market equilibrium and at the optimal solution. Then it turns to the issue of decentralizing the optimal solution with various taxes and transfers. Depending on the available instruments,...

This paper establishes, in the context of the Diamond (1965) overlapping generations economy with production, that the risk that savings in unbacked assets (like fiat money or public debt) become worthless implies that, not only the first-best steady state, but even the best steady state...

I show in this paper that in an overlapping generations economy with production à la Diamond (1970) in which the agents can only save in terms of capital (i.e. with no asset bubbles à la Tirole (1985) or public debt as in Diamond (1965)), there is a period-by- period balanced fiscal policy...

Then it turns to the issue of decentralizing the optimal solution with various taxes and transfers. Depending on the available instruments,...

The achievements and limitations of the classical theory of optimal labor-income taxation based on social welfare functions are now well known, although utilitarianism still dominates public economics. We review the recent interest that has arisen for broadening the normative approach and making...

Nous proposons une méthode pour évaluer la capacité des systèmes de taxation du revenu de diminuer la pauvreté, lorsque celle-ci est définie en cohérence avec une notion de niveau de vie issue de l’éthique de la responsabilité. Selon cette éthique, toutes les inégalités ne sont pas...

This thesis consists of a summary and four self-contained papers. <p> Paper [I] Following the 1987 report by The World Commission on Environment and Development, the genuine saving has come to play a key role in the context of sustainable development, and the World Bank regularly publishes numbers...</p>

This paper concerns optimal income taxation in a two-country OLG economy, where each country is characterized by asymmetric information between the government and the private sector, and where one of the countries outsources part of its production to the other. In the country whose firms...

This paper concerns optimal taxation and environmental policy in the presence of transboundary environmental damage and labour market distortions, where the latter gives rise to wage bargaining externalities between countries. I consider a decentralized economic federation where the federal...

This paper concerns the optimal provision of a state-variable public good, where the global climate is the prime example. The analysis is based on a two-type optimal income tax model with overlapping generations, where people care about their relative consumption. We consider both...
