Agents frequently have different opinions on where to locate a public facility. While some agents consider the facility a good and prefer to have it nearby, others dislike it and would like to see it built far away from their own locations. To aggregate agents' preferences in these situations,...

This chapter briefly reviews the present state of judgment aggregation theory and tentatively suggests a future direction for that theory. In the review, we start by emphasizing the difference between the doctrinal paradox and the discursive dilemma, two idealized examples which classically...

Judgment aggregation theory generalizes social choice theory by having the aggregation rule bear on judgments of all kinds instead of barely judgments of preference. The paper briefly sums it up, privileging the variant that formalizes judgment by a logical syntax. The theory derives from...

Economists have used the term “nonbinary” to describe both choice functional nonbinariness (choice functions that cannot be rationalized as the maximizing outcome of a binary preference relation) and structural nonbinariness (the structure of the model dictates that pairs of alternatives do...

Conventional public choice literature suggests that interest groups have a largely malign effect upon the economy. Suggesting that interest groups are primarily established to lobby governments for rents, the public choice approach essentially rests upon normative presumptions concerning the...

Why are some lobby groups less benign in their external effects than others? Nearly three decades ago, Mancur Olson (1982) proposed that less-encompassing lobby groups with their constituents collectively representing a narrow range of sectors are more apt to seek the types of subsidies,...

I consider a society with heterogeneous individuals who can form organizations for the production of a differentiated service. An arrangement of organizations is said to be split up stable when there is no majority to split any of the organizations. Unlike other equilibrium concepts in the...

This paper presents ‘crypto public choice’ which examines the economics of collective decision making in the functioning of blockchain protocols and among related communities of users. We introduce the blockchain community to public choice theory and show how it can be applied to the study...

This paper studies the strategic foundations of the Representative Voter Theorem (Rothstein, 1991), also called the second version of the Median Voter Theorem. As a by-product, it also considers the existence of non-trivial strategy-proof social choice functions over the domain of...

In this note, three major areas of Buchanan's research are briefly described: (1) The ideas of Knut Wicksell on Buchanan's work, (2) constitutional economics and the veil of ignorance, and (3) the role of government and/or the power to tax. It is shown that these three areas had a major...
