We explore the relationship between proportionality and manipulation (via merging or splitting agents' claims) in bankruptcy problems. We provide an alternative proof to the well-known result that, in an unrestricted domain, immunity to manipulation is equivalent to requiring proportional...

This article studies a model of coalition formation for the joint production (and finance) of public projects, in which agents may belong to multiple coalitions. We show that, if projects are divisible, there always exists a stable (secession-proof) structure, i.e., a structure in which no...

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...

Standard models for the evaluation of population health, such as the so-called models of aggregate Quality Adjusted Life Years (QALYs), or aggregate Healthy Years Equiva- lent (HYEs), are usually criticized on equity grounds. We provide in this paper normative justi_cations for alternative...

In this paper we explore the implications of fundamental principles for the evaluation of population health. We formalize those principles as axioms for social preferences over dis- tributions of health for a given population. We single out several focal population health evaluation functions,...

We explore in this paper the axiomatic approach to the problem of sharing the revenue from museum passes. 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 consider the problem of assigning agents to a facility, represented by slots on a line, where only one agent can be served at a time. There is a finite number of agents, and each one wants to be served as close as possible to his preferred slot. We first consider deterministic assignment of...

We analyze a general model of rationing in which agents have baselines, in addition to claims against the (insufficient) endowment of the good to be allocated. Many real-life problems fit this general model (e.g., bankruptcy with prioritized claims, resource allocation in the public health care...

We analyze a general model of rationing in which agents have baselines, in addition to claims against the (insufficient) endowment of the good to be allocated. Many real-life problems fit this extended model (e.g., bankruptcy with prioritized claims, resource allocation in the public health care...

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...
