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...

We consider allocation problems with indivisible goods when agents' preferences are single-peaked. We propose natural rules (called up methods) to solve such a class of problems. We analyzed the properties those methods satisfy and we provide a characterization of them. We also prove that these...

This paper provides a discussion on the empirical findings surrounding the design of human development, inequality and poverty measures. We focus on the United Nations Development Program approach to those issues, in particular regarding the human development index and the multidimensional...

This paper is devoted to the discussion of the measurement of human development and poverty, especially in United Nations Development Program’s global Human Development Reports. We first outline the methodological evolution of different indices over the last two decades, focusing on the...
