| Abstract: | In this paper an attempt is made to derive two interval utility measures for public goods. The domain of the measures is partitioned into priority classes in such a way that each class contains an element, called a kernel, which can be moved by parameter variation to the immediately preceding class. The “expansion path” from priority class to priority class is determined by an optimality criterion. The measures themselves are based on optimality conditions that are similar to the familiar first-order conditions of consumer analysis. One is a product measure and the other one is additive. |
