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

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.

In this paper we provide two simple new versions of Arrow's impossibility theorem, in a model with only one preference profile. Both versions are transparent, requiring minimal mathematical sophistication. The first version assumes there are only two people in society, whose preferences are...

This paper develops two straightforward value of life models; one is a probabilistic value of life model and the second is a determinstic value of time model. Simplifying assumptions allow both models to be solved analytically. Constant relative risk aversion utility functions are used, and both...

This paper modifies the standard tort model by introducing role-type uncertainty, that is, it is assumed that neither party knows in advance whether she will become the victim or the injurer when an accident occurs. When the standards of care of the two parties are assumed to be set at the...

Judge Learned Hand’s opinion in United States v. Carroll Towing Co. (1947) is canonized in the law and economics literature as the first use of cost-benefit analysis for determining negligence and assigning liability. This paper revisits the original case in which the famous Hand formula was...

In this paper we discuss a new tort liability rule, which we call super-symmetric comparative negligence and vigilance. When both injurer and victim in an accident are negligent, it provides for liability shares that depend on the degrees of negligence of the two parties, similar to the standard...

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 explore the...
