This paper reconsiders the debate around the political determination of capital income taxes and explains why such taxes survive in most OECD countries. The political economy literature on redistributive politics (Persson and Tabellini 2003) emphasizes the role played by the lower class in the...

This paper studies the optimal fiscal treatment of addictive goods (cigarettes, drugs, fatty foods, alcohol, gambling etc.). It shows that, when agents have private information about their productivity levels and their degree of rationality, the Atkinson and Stiglitz result of optimal uniform...

We study a supply chain model where competing manufacturers located around a circle contract with privately informed and exclusive retailers. The number of brands in the market (determined by the manufacturers’ zero profit condition) depends on the level of asymmetric information within supply...

We revisit the choice of product differentiation by competing firms in the Hotelling model, under the assumption that firms are vertically separated, and that retailers choose products’ characteristics. We show that retailers with private information about their marginal costs choose to...

This paper studies an optimal taxation problem in a dynamic economy inhabited by individuals who differ in productivity (as in Kocherlakota, 2006) and in the short-term discount factor. We determine incentive compatible Pareto optimal allocations in a multidimensional screening model where...

This paper studies if external commitment devices are effectively capable of helping agents to reduce their consumption of addictive goods (alcohol, cigarettes, drugs, fatty foods etc.). The main assumption introduced in the model is that individuals are sophisticated hyperbolic discounters. The...

Strotz (1956) first suggested that individuals are more impatient when making short-run tradeoffs than long-run ones. Many experimental studies supports his conjecture. Motivated by recent evidence from the British Department of Work and Pension (2006), this paper applies this behavioral...

Motivated by the recent experimental evidence on altruistic behavior, we study a simple principal-agent model where each player cares about other players’ utility, and may reciprocate their attitude towards him. We show that, relative to the selfish benchmark, efficiency improves when players...
