This paper extends standard agency theoretic models to explicitly take into account the presence of multiple criteria at the agent level. Two possible approaches for this extension are discussed. In the first approach, we consider only the minimum information that the principal might posses...

One problem impeding the use of linear decision models in practical applications is the difficulty in precisely specifying weights. In this paper, we analyze an approach to establish the stability of a decision, given approximate information on weights. This approach is based on comparing the...
