For a large class of additive random utility discrete choice models with income effects, we compute the probability distribution of the compensating variation. We show that the cumulative distribution function only depends on the choice probabilities. Our results are used to compute the...

De tous les problèmes conçus par la théorie de la décision, le paradoxe d'Allais est peut-être celui qui aura suscité l'intérêt le plus persistant. La théorie y a consacré assez de travaux techniques remarquables pour qu'il soit désormais possible à l'histoire et à la philosophie...

In the heart of the Great Crisis, amidst great uncertainty and concerns surrounding the future of capitalism, John Maynard Keynes launched his optimistic prophecy that growth and technological change would allow mankind to solve its economic problem within a century. He envisioned a world where...

We consider Rubinstein's two-person alternating-offer bargaining model with two-sided incomplete information. We investigate the effects of one party having relative concerns on the bargaining outcome and the delay in reaching an agreement. We find that facing an opponent having stronger...

Behavioral economics has shaken the view that individuals have well-defined, consistent and stable preferences. This raises a challenge for welfare economics, which takes as a key postulate that individual preferences should be respected. We agree with Bernheim (2009) and Bernheim and Rangel...

We consider a model of wage determination with private information in a duopoly. We investigate the effects of unions having relative concerns on the negotiated wage and the strike activity. We show that an increase of unions' relative concerns has an ambiguous effect on the strike activity.

We study a model in which heterogenous agents first form a trading network where link formation is costless. Then, a seller and a buyer are randomly selected among the agents to bargain through a chain of intermediaries. We determine both the trading path and the allocation of the surplus among...

A nudge is a non-coercive paternalistic intervention that attempts to improve choices by manipulating the framing of a decision problem. As any paternalism, it faces the difficulty of determining the appropriate welfare criterion. We propose a welfare-theoretic foundation for nudging similar in...

A social state is irreducible if, and only if for any non-trivial partition of individuals with two groups, there exists another feasible social state at which every individual in the first group is equally well-off and someone strictly better-off. Competitive equilibria decentralize irreducible...

At a Nash - Walras equilibrium, individuals exchange commodities competitively, and, simultaneously, they interact strategically. Under standard assumptions, NashWalras equilibria exist, equilibrium profiles of actions are, typically, determinate but Pareto suboptimal, though not constrained...
