Resource egalitarianism and welfare egalitarianism are two focal conceptions of distributive justice. We show in this paper that they share a solid common ground. To do so, we analyze a simple model of resource allocation in which agents’ abilities (to transform the resource into an...

We investigate the implications and logical relations between progressivity (a principle of distributive justice) and merging-proofness (a strategic principle) in taxation. By means of two characterization results, we show that these two principles are intimately related, despite their different...

In this work we deal with the theory of price determination in Steuart’s writings; in particular with the concept of Double competition. The background is the evolution of the concept of market during the 18th century. Steuart proposed a theoretical construction in order to tackle the problem...

Competitive pricing is a pricing rule that combines two principles that are present in competitive markets. The profit principle (an action will be chosen only if it yields maximal payoffs), and the scarcity principle (markets make expensive those commodities that restrict production...

The purpose of this paper is to re-examine the notion of price determination in A.-R.-J. Turgot’s writings. Consideration is given to the evolution of the concept of market during the 18th century. It is argued that Turgot provided a model of multiple exchanges with merchants, called General...

We study how a behavior (an idea, buying a product, having a disease, adopting a cultural fad or a technology) spreads among agents in an a social network that exhibits segregation or homophily (the tendency of agents to associate with others similar to themselves). Individuals are distinguished...

We study optimal wage schemes for teams, under the presence of budget constraints, in a model in which agents’ effort decisions are mapped into the probability of the team’s success. We show that (first-best) efficiency can only be attained with complex contracts that are vulnerable to ex...

Based on the ethical principle of equality of opportunity, this paper presents a measure of the welfare loss that is caused by an unfair distribution of a particular outcome (income, health, education, etc). The key idea is that a fair society should produce outcomes that depend on...

We provide a general coalitional procedure that characterizes a family of rules for bankruptcy problems inspired by the Talmud.

We consider the problem of assigning agents to slots on a line, where only one agent can be served at a slot and each agent prefers to be served as close as possible to his target. Our focus is on aggregate gap minimizing methods, i.e., those that minimize the total gap between targets and...
