This chapter provides a survey of utilitarian theories of justice. We review and discuss axiomatizations of utilitarian and generalized-utilitarian social-evaluation functionals in a welfarist framework. Section 2 introduces, along with some basic definitions, social-evaluation functionals....

We investigate how individuals think groups should aggregate members' ordinal preferences - that is, how they interpret "the will of the people." In an experiment, we elicit revealed attitudes toward ordinal preference aggregation and classify subjects according to the rules they apparently...

Social marginal welfare weights play an important role in areas of applied public policy analysis such as tax reform. These weights reflect the values of the social planner, or equivalently the underlying social welfare function. A number of recent papers have questioned the "default"...

Much economic analysis derives policy recommendations based on social welfare criteria intended to model the preferences of a policy maker. Yet, little is known about policy maker's normative views in a way amenable to this use. In a behavioral experiment, we elicit German legislators' social...

We study alternative institutional arrangements for the determination of monetary policy in a general equilibrium model with heterogeneous agents, where monetary policy has redistributive effects. Inflation is determined by a policy board using either simple-majority voting, supermajority...

In this paper we are concerned with the following question. Given an extended preference ordering under what conditions does there exist an empirical stochastic/social choice function which generates it? We use Farkas' lemma to obtain a necessary and sufficient condition under which such a...

This chapter reviews the SWFL approach to social choice. It does not attempt to be a complete and systematic survey of existing results, but to give a critical assesment of the main axioms and their role in filtering the ethically relevant information, in particular the measurability and...

Fuzzy set theory has been explicitly introduced to deal with vagueness and ambiguity. One can also use probability theory or techniques borrowed from philosophical logic. In this chapter, we consider fuzzy preferences and we survey the literature on aggregation of fuzzy preferences. We restrict...

We introduce the concept of a social choice functional and provide two axiomatic characterizations of the utilitarian social choice functional. Subsequently we consider Harsanyi's weighted utilitarianism and establish two more propositions concerning the same. While the first is an axiomatic...
