We consider a model of social interactions in which agents are assumed to acquire information from others through a certain sampling process that generates an influence network. These networks comprise a wide array of options depending on the level of correlation assumed between agents' in and...

Some behaviors, ideas or technologies spread and become persistent in society, whereas others vanish. This paper analyzes the role of social influence in determining such distinct collective outcomes. Agents are assumed to acquire information from others through a certain sampling process that...

We study the optimal management of teams in which agents’ effort decisions are mapped (via a production technology) into the probability of the team’s success. Optimal wage schemes in such context are largely discriminatory, but we show that the extent of the discrimination crucially depends...

In a recent article, Fragnelli and Gagliardo [Cooperative models for allocating an object, Economics Letters 117 (2012) 227-229] propose several procedures to solve a basic problem of fair allocation. We scrutinize their proposal and contextualize it into recent developments of the literature on...

We explore in this paper the axiomatic approach to the problem of sharing the revenue from bundled pricing. We formalize two models for this problem on the grounds of two different informational bases. In both models, we provide axiomatic rationale for natural rules to solve the problem. We,...

We introduce a new operator for general rationing problems in which, besides conflicting claims, individual baselines play an important role in the rationing process. The operator builds onto ideas of composition, which are not only frequent in rationing, but also in related problems such as...

In a recent paper, Thomson and Yeh [Operators for the adjudication of conflicting claims, Journal of Economic Theory 143 (2008) 177-198] introduced the concept of operators on the space of rules for the problem of adjudicating conflicting claims. They focussed on three operators in order to...

We explore the implications of four natural axioms in taxation: continuity (small changes in the data of a taxation problem should not lead to large changes in the tax allocation), equal treatment of equals (agents with the same pre-tax incomes pay equal taxes), consistency (the way in which a...
