This article provides an introduction to the use of social welfare functions for the comparative evaluation of social alternatives. Three main approaches are considered: Bergson–Samuelson social welfare functions, Arrovian social welfare functions, and Sen's social welfare functionals....

Majority voting over the nonlinear tax schedules proposed by a continuum of citizen candidates is considered. The analysis extends the finite-individual model of Röell (unpublished manuscript, 2012). Each candidate proposes the tax schedule that is utility maximal for him subject to budget and...

In Democratic Reason, Hélène Landemore has built a case for the epistemic virtues of inclusive deliberative democracy based on the cognitive diversity of the group engaged in making collective decisions. She supports her thesis by appealing to the Diversity Trumps Ability Theorem of Lu Hong...

There are a number of single-profile impossibility theorems in social choice theory and welfare economics that demonstrate the incompatibility of dominance criteria with various nonconsequentialist principles given some rationality restrictions on the rankings being considered. This article is...

We consider the classic puzzle of why people turn out for elections in substantial numbers even though formal analysis strongly suggests that rational agents would not vote. If one assumes that voters do not make systematic mistakes, the most plausible explanation seems to be that agents receive...

We explore the potential for correlated equilibrium to capture conformity to norms and the coordination of behavior within social groups. Given a partition of players into social groups we propose properties that one may expect of a correlated equilibrium: within-group anonymity, group...

In this paper, we study several general equilibrium models in which the agents in an economy must decide on the appropriate level of immigration into the country. Immigration does not enter directly into the native agents' utility functions, and natives have identical preferences over...
