This chapter discusses different types of domain restrictions. We begin by analyzing various qualitative conditions on preference profiles. Value-restricted preferences (with single-peaked preferences as one of its subcases), limited agreement as well as antagonistic and dichotomous preferences...

Given a set of outcomes that affect the welfare of the members of a group, K.J. Arrow imposed the following five conditions on the ordering of the outcomes as a function of the preferences of the individual group members, and then proved that the conditions are logically inconsistent: • The...

Constitutional theorizing typically employs a bi-level analytical framework wherein the choice of rules precedes the actions that people pursue within those rules. Constitutions are thus products of planning and are prior to the spontaneous ordering that characterizes market processes. This...

We propose a new voting system, satisfaction approval voting (SAV), for multiwinner elections, in which voters can approve of as many candidates or as many parties as they like. However, the winners are not those who receive the most votes, as under approval voting (AV), but those who maximize...

When a society overthrows a ruler - call the ruler Caesar - what determines whether Caesar is killed or enslaved? This paper presents a model of killing versus enslaving Caesar, based on a new theory which unifies justice, status, and power. The model pertains to societies which value ordinal...

This paper provides an overview of Buchanan's constitutional political economy, as it emerged over the course of fifty years. This was the field in which James Buchanan devoted the most effort and to which he made the largest contributions. Although the finely grained arguments that he developed...

We establish that the fraction of preference profiles for which the random serial dictatorship allocation is ordinally efficient vanishes for allocation problems with many object types. We consider also a probabilistic setting where in expectation agents have moderately similar preferences...

This paper provides characterization theorems for preferences that can be represented by the minimum, the maximum, and the sum of components, or combinations of these forms. It contains a discussion of applications to social choice

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...
