In this short paper we provide two simple new versions of Arrow's impossibility theorem, in a world with only one preference profile. Both versions are extremely transparent. The first version assumes a two-agent society; the second version, which is similar to a theorem of Pollak, assumes two...

In this paper we provide a simple new version of Arrow’s impossibility theorem, in a world with only one preference profile. This theorem relies on a new assumption of preference diversity, and we explore alternative notions of preference diversity at length.

Logically satisfactory methods for narrowing the range of social choice can be designed. For example, the SDF which transforms (S, R) into P(S, R), that is, the Pareto rule, satisfies all the conditions imposed on C(·) in Theorem 9: The Pareto rule is normal. For if x ∈ P(S, R) and y ∈ S,...

In this paper I have developed a mostly new graphical technique for analyzing government expenditure and, particularly, for analyzing how expenditure grows. The analysis assumes that government has the power to set agendas that are straight lines in the space of issues, and that voters choose...

A growing body of literature suggests that courts and juries are inclined toward division of liability between two strictly non-negligent or “vigilant†parties. However, standard models of liability rules do not provide for vigilance-based sharing of liability. In this paper, we...

A growing body of literature suggests that courts and juries are inclined toward division of liability between two strictly non-negligent or "vigilant" parties. In this paper, we explore the economic efficiency of liability rules based on comparative vigilance. We devise rules that are efficient...
