We propose in this article some new extensions of the well-known social preferences model of Fehr and Schmidt [1999]: the introduction of opponents? payoffs differences and a simple element of reciprocity. To test their robustness, we estimate fixed-effects Logit models with collected data on a...

The burden sharing of pollution abatement costs, e.g. in the Kyoto protocol context, raises the debated question to know who (which country or which region) should bear what cost. With a model of specific factors reflecting international specialization, we show that it is impossible to abate...

This paper examines a reform of the French welfare system. More precisely, it is a question of granting a decreasing benefit according to earned income. The modulation of this benefit according to the family size and the rent is clarified in detail. Several alternatives of the reform are...

Many recent analyses have attempted to measure and explain income-related health and health care inequalities in France. Nevertheless aspects related to equity have not systematically been emphasised. This paper considers the question of equity in recent empirical research. It adopts a...

How to understand the frequently conflicting relationships between sociology and economy? Noticing that the accusations which are exchanged from one discipline to the other are most often unconvincing, we will propose the following interpretation: underlying these oppositions one can identify a...

To evaluate the inequality effects of 35 hours, we use a very general labour demand framework taking into account various skills and the impact of the work duration on wages, productivity and labour organization. Numerical simulations include several constituents of devices Aubry and consider...

This paper presents various effects of three simulated reforms of the European pay-as-you-go system. These are investigated with INGENUE : a multi-region, general equilibrium, overlapping-generation model of the world economy. Reforms are presented around a baseline scenario where constant...

We estimate structural models of guilt aversion to measure the population level of willingness to pay (WTP) to avoid feeling guilt by letting down another player. We compare estimates of WTP under the assumption that higher-order beliefs are in equilibrium (i.e. consistent with the choice...

I provide a selective review of discounting and climate policy. After reviewing evidence on the importance of the discount rate in setting policy, I ask whether standard models tend to exaggerate the sacrifices that the current generation needs to undertake in order to internalize climate...
