Or, since optimal choices would be highly dependent on the identity of players, can single dominant strategies still be devised to deal effectively with opponents with variable payoffs (and therefore with unpredictable strategies).
All four payoff variables reveal significant differences between their base tertile and higher tertiles in respect to completion, although for the benefit to employment, salary, and occupational status, although their impact is limited to about one percentage point difference in terms of completion outcomes.
The variable 'C' in this payoff matrix is a finite number that weighs the costs and benefits described above.
For the EGT model this is represented by the variable α in the payoff table.
Standard economic models of contract imply that contracts should be highly "complex," by which we mean (1) rich in the expected number of payoff-relevant contingencies; (2) variable in the magnitude of payoffs contracted to flow between parties; and (3) severe in the cognitive load necessary to understand the contract.
In variable-sum games each payoff depends on both players' actions.
Table 3In variable-sum games each payoff depends on both players' actions.
For parsimony, we considered decision variables (corresponding to the payoff estimate of each bandit) that avoid latent or hierarchical inferences that might take place in the course of the experiment.
We introduce a payoff matrix with variable size to capture mutations and extinctions.
To capture the interactions of different types, we employ a payoff matrix of variable size and thus are able to accommodate an arbitrary number of mutations.
Since in a normal distribution the probability P(X ≤ x) = P (Z ≤ (x - μ)/σ), where μ is the distribution mean, σ the standard deviation and Z the standard normal variable [ 29], the probability the lower payoff is higher than the higher payoff, when both vary as ~ N (0, 1), is: 1 - P (Z < (0 + 1) /√ 2), = 1 - P (Z < 0.707), = 1 - 0.76, = 0.24.
