Relative Nash Welfarism
نویسنده
چکیده
Relative Nash welfarism is a solution to the problem of aggregating von NeumannMorgenstern preferences over a set of lotteries. It ranks such lotteries according to the product of any collection of 0—normalized von Neumann-Morgenstern utilities they generate. We show that this criterion is characterized by the Weak Pareto Principle, Anonymity, and Independence of Harmless Expansions: the social ranking of two lotteries is unaffected by the addition of any alternative that every agent deems at least as good as the one she originally found worst. Relative Nash welfarism is more appealing than relative utilitarianism in contexts where the best relevant alternative for an agent is diffi cult to identify with confidence.

Axiomatic Bargaining on Economic Environments with Lotteries∗
Most contributions in axiomatic bargaining are phrased in the space of utilities. This comes in sharp contrast with standards in most other branches of economic theory. The present paper shows how Nash’s original axiomatic system can be rephrased in a natural class of economic environments with lotteries, and how his uniqueness result can be recovered, provided one completes the system with a p...
متن کاملMulti_profile welfarism: a generalization
This paper characterizes welfarist social evaluation in a multi-profile setting where, in addition to multiple utility profiles, there may be more than one profile of nonwelfare information. We prove a new version of the welfarism theorem in this alternative framework, and we demonstrate that adding a plausible and weak anonymity property to the welfarism axioms generates welfarist social-evalu...
متن کاملWelfarism vs. extra-welfarism.
'Extra-welfarism' has received some attention in health economics, yet there is little consensus on what distinguishes it from more conventional 'welfarist economics'. In this paper, we seek to identify the characteristics of each in order to make a systematic comparison of the ways in which they evaluate alternative social states. The focus, though this is not intended to be exclusive, is on h...

This paper characterizes welfarist social evaluation in a multi-profile setting where, in addition to multiple utility profiles, it is assumed that there are several profiles of non-welfare information. We prove new versions of the welfarism theorems in this alternative framework, and we illustrate that a very plausible and weak anonymity property is sufficient to generate anonymous social-eval...
