We endow individuals that differ in skill levels and tastes for working with altruistic preferences for redistribution in a voting model where a unidimensional redistributive parameter is chosen by majority voting in a direct democracy. When altruistic preferences are desert-sensitive, i.e. when...

This paper reports an experimental study on three well-known solutions for problems of adjudicating con icting claims: the constrained equal-awards, the proportional, and the constrained equal-losses rules. We first let subjects play three games designed such that the unique equilibrium...

A set of agents with possibly different waiting costs have to receive the same service one after the other. Efficiency requires to maximize total welfare. Equity requires to at least treat equal agents equally. One must form a queue, set up monetary transfers to compensate agents having to wait,...

In this paper we consider a model with multiple jurisdictions where each formed jurisdiction selects a public project from the given uni-dimensional set, equally shares its cost among its members and places the project at the location of its median resident. We examine a cooperative concept of...

In this note we consider a society that partitions itself into disjoint jurisdictions, each choosing a location of its public project and a taxation scheme to finance it. The set of public project is multi-dimensional, and their costs could vary from jurisdiction to jurisdiction. We impose two...

This paper shows how the role of the market, the state and the family in providing financial support at old age has evolved over time with changes in factors such as the reliability and the effectiveness of family support, the rate of interest, the cost of public funds and earning inequality. We...

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,...

In this paper we study the optimal design of a long term care policy in a setting that includes three types of care to dependent parents: public nursing homes, financial assistance by children and assistance in time by children. The instruments are public nursing homes and subsidies to aiding...

We explore the evolutionary dynamics of a population that consists of cooperators and defectors, wherein each member of the many pairs of players of a one-shot prisoner's dilemma game is drawn at random, and the number of descendents positively depends on the payoffs in the game. We demonstrate...

In their recent paper Goeree et al. (2005) determine that all-pay auctions are better for fundraising activities than lotteries. We show that the introduction of asymmetry among valuations with complete information could reverse this result. Complete information seems well suited to some charity...
