A collective decision problem is described by a set of agents, a profile of single-peaked preferences over the real line and a number k of public facilities to be located. We consider public facilities that do not suffer from congestion and are non-excludable. We provide a characterization of...

This paper studies the problem of fairly allocating an amount of a divisible resource when preferences are single-peaked. We characterize the class of envy-free and peak-only rules and show that the class forms a complete lattice with respect to a dominance relation. We also pin down the...

Climate change is an externality since those who emit greenhouse gases do not pay the long-term negative consequences of their emissions. In view of the resulting inefficiency, it has been claimed that climate policies can be evaluated by the Pareto principle. However, climate policies lead to...

Are the probable future negative effects of climate change an argument for decreasing the discount rate to promote the interests of future generations? The analysis of the present paper suggests that such stronger intergenerational altruism might undermine future wellbeing if not complemented by...

We model problems of allocating disputed properties as generalized exchange economies. Therein, agents have preferences and claims over multiple goods, and the social endowment of each good may not be sufficient to satisfy all individual claims. We focus on market-based allocation rules that...

The case for progressive income taxation is often based on the classic result of Jakobsson (1976) and Fellman (1976), according to which progressive and only progressive income taxes - in the sense of increasing average tax rates on income - ensure a reduction in income inequality. This result...

The paper presents the results of a lab-in-the-field experiment in three South African townships located in the suburbs of Cape Town. The experimental design consists of a set of decisions on how the members of a naturally occurring group allocate an endowment to a private or to a public...

In this paper we propose different criteria to rank income distributions according to equality of opportunity. Different from existing ones, our criteria explicitly recognize the interplay between circumstances and effort. We characterize them axiomatically and we compare them with existing...

We suggest that procedures of monetarized bidding can facilitate co-operation in Elinor Ostrom type common(s) projects without crowding out communitarian faculties of "self-governance". Axioms securing procedurally egalitarian bidding on the basis of declared monetary evaluations are introduced....

This paper explores the view that a criterion of intergenerational equity serves to make choices according to ethical intuitions on a domain of relevant technological environments. In line with this view I first calibrate different criteria of intergenerational equity in the AK model of economic...
