Abstract: | This article reports an experimental study of decision-making outcomes in cooperative non-sidepayment games. The objective of this test was to determine which characteristic function, V
(S) or V
(S), provides the most accurate basis for payoff predictions from solution concepts. The experiment tested three solution concepts (core, stable set, imputation set) in the context of 5-person, 2-strategy non-sidepayment games. Predictions from each of the three solution concepts were computed on the basis of both V
(S) and V
(S), making a total of six predictive theories under test. Consistent with earlier studies (Michener et al., 1984a; Michener et al., 1985), two basic findings emerged. First, the data show that for each of the solutions tested, the prediction from any solution concept computed from V (S) was more accurate than the prediction from the same solution concept computed from V
(S). Second, the -core was the most accurate of the six theories tested. Overall, these results support the view that V
(S) is superior to V
(S) as a basis for payoff predictions in cooperative non-sidepayment games. |
