One of the great virtues of structural equation models is that they permit the quantification of causal and noncausal sources of statistical relationship. The present article discusses efficient matrix methods of computation for effect decomposition and extends these methods to models with...

This article attempts to explain negatively correlated disturbances in "parallel" simultaneous-equation models in which each equation contains essentially the same variables as the others but is written for a different position of the social system under study. The two general methodological...

Classes of two-person zero-sum games termed "equivalent games" are defined. These are games with identical value and identical optimal mixed-strategies but with different matrix entries and thus different opportunities for exploiting a nonrational opponent. An experiment was conducted to...

Three different presentation formats of the same Prisoner's Dilemma game were investigated. Fifteen pairs of male subjects were assigned to each of three experimental conditions. One group played a conventional matrix representation of the game, one group played an expected value representation...
