This paper discusses Hamiltonian necessary conditions for a non-smooth multiobjective optimal control problem with endpoint constraints related to a general preference. The transversality condition in our necessary conditions is stated in terms of a normal cone to the level sets of the preference. Examples for a number of useful preferences are discussed.

This paper develops a reduced form method of controlling for differences in information sets of subjects in public good discrete choice models, using stated preference data. The main contribution of our method comes from accounting for the effect of information provided during a survey on the mean and the variance of individual-specific scale parameters. In this way we incorporate both scale he...

Notwithstanding the general acceptance of the value of statistical life (VSL) estimates for policy assessment purposes, several important unresolved issues remain. First, the results from revealed preference studies are systematically higher than those from stated preference studies, potentially limiting the usefulness of stated preference studies in generalizing the VSL estimates to different ...

In this paper we address the problem of choosing the best solution(s) from a set of interpretations of the same object (in our case a segment of text). A notion of preference is stated, based on pairwise comparisons of complete interpretations in order to obtain a partial order among the competing interpretations. An experimental implementation is described, which uses Prolog-like preference st...
