Two theorems are derived about social choice functions, which are defined on comprehensive convex subsets of utility allocation space. Theorem 1 asserts that a linearity condition, together with Pareto optimality, implies that a social choice function must be utilitarian. Theorem 2 asserts that a concavity condition, together with Pareto optimality and independence of irrelevant alternatives, implies that a social choice function must be either utilitarian or egalitarian. These linearity and… 

Consumption, Risk, and Prioritarianism

Most economic problems combining risk and equity have been studied under utilitarianism. As an alternative, we study consumption decisions under risk assuming a prioritarian social welfare function.

Linear and Utilitarian Choice Functions: Revisiting Myerson's Theorem

Myerson proved that every linear and weakly Paretian choice function is utilitarian. We revisit his model and result for the two-person case and supplement it with an “only if” direction. That is, we

Timing effect in bargaining and ex ante efficiency of the relative utilitarian solution

In this note, I provide an axiomatic characterization of the relative utilitarian bargaining solution (RU) to Nash (Econometrica 18:155–162, 1950) bargaining problems. The solution is obtained when

Disagreement point monotonicity, transfer responsiveness, and the egalitarian bargaining solution

This paper provides an axiomatization of the egalitarian bargaining solution. The central axiom used (together with some standard properties of bargaining solutions) in this characterization is a

Heterogeneous economies : implications for inequality and financial stability

In the first chapter we explore the relationship between income inequality and the Utilitarian ethic in a dynamic environment with endogenous preferences. Classical Utilitarians, like Bentham,

Utilitarianism with and without expected utility




Equity and the Informational Basis of Collective Choice

We consider the problem of a planner or ethical observer who wants to derive a collective preference ordering over a set of feasible alternatives from the knowledge of individual utility functions.

Nonlinear social welfare functions

It is argued that Bayesian decision theory is a solution of an important philosophical problem, viz. the problem of how to define rational behavior under risk and uncertainty. The author has shown in

Cardinal Welfare, Individualistic Ethics, and Interpersonal Comparisons of Utility

The naive concept of social welfare as a sum of intuitively measurable and comparable individual cardinal utilities has been found unable to withstand the methodological criticism of the Pareto

Social Choice and Individual Values

Originally published in 1951, Social Choice and Individual Values introduced "Arrow's Impossibility Theorem" and founded the field of social choice theory in economics and political science. This new

Interpersonal Comparability and Social Choice Theory

At a general level, the information that may be required to enable a planner to judge which of two states is socially preferable may be of a diverse character. It is convenient to partition this

A Theorem on Utilitarianism

In a recent paper [1], d'Aspremont and Gevers establish that if a social welfare functional (SWFL) satisfies several reasonable properties, and if interpersonal comparisons of absolute welfare levels

The super-additive solution for the Nash bargaining game

The feasible set in a Nash bargaining game is a set in the utility space of the players. As such, its points often represent expectations on uncertain events. If this is the case, the feasible set
