It is generally accepted that moving from an unfunded to a funded social security sys- tem implies a welfare loss for the transition generation, that is the generation that has to pay twice: first, saving for its own retirement and second, contributing to the pensions of the then retired...

The purpose of this paper is to provide a critical evaluation of theoretical models showing that shifting from pay-as-you-go to funded social security schemes can be made Pareto-improving. Further, it argues that what often makes a reform toward funded schemes attractive is a number of...

This paper addresses the issue of optimum population with two concerns : avoiding both the absolute repugnant solution that amounts to giving to an infinite number an infinitesimal amount and the marginal repugnant solution in which equilibrium consumption decresases with income. To avoid these...

This paper examines efficiency rationales behind uniformity of taxation for public projects. Let a benevolent risk neutral 'constitutional designer' to set an optimal cost-sharing rule for a legislature operating under majority rule. Then the designer will choose 'more equal taxes' for a country...

We study the impact of transfer pricing rules on sales prices, firms’ organizational structure, and consumers’ utility within a two-country monopolistic competition model featuring source-based profit taxes that differ across countries. Firms can either become multinationals, i.e., they...

We analyze the two-country model of fiscal competition of Kanbur and Keen (1993) where countries differ in size and use a commodity tax to reach their objective of revenue maximization. Due to fiscal externalities, the non-cooperative outcome is inefficient. Besides, the international optimum...

Despite the fact that all developed economies levy broadly-based indirect taxes alongside direct taxes, little theory is devoted to explaining the direct-indirect tax mix. Our purpose is to show that if different taxes have different evasion characteristics, some optimal tax mix emerges...
