Extensions of Value Solutions in Constant-Sum Non-Sidepayment Games

This article defines two new solution concepts for non-sidepayment games - the λ-transfer nucleolus and the λ-transfer disruption value - and reports the results of an experiment testing their predictive accuracy against that of a third solution concept, the well-known λ-transfer value (Shapley, 1969). The test was based on data from a laboratory experiment utilizing five-person, two-choice games that were constant-sum in normal form. Goodness-of-fit results show that the λ-transfer value and the λ-transfer disruption value were about equally accurate in predicting the observed payoffs to players in these games; both of these solutions were more accurate than the λ-transfer nucleolus.
