Primary Outcomes (end points)
Our primary outcomes are the pairwise comparisons for the behavior of subjects between two treatments. With these pairwise comparisons, we test the hypotheses derived from our behavioral game theoretical model. These comparisons concern the (i) self selection of principals, the frequency of cooperating FMs, and the frequency of SMs who cooperate after the FM has cooperated. For the principal’s self selection, we have only one hypothesis:
Hypothesis 1 (Self selection): The frequency of principals choosing FM is higher in treatment T than in treatment O.
For FMs, our model yields the following order for the frequency of cooperative choices: The frequency is highest for principals who have self selected to FM in treatments T and O, followed by subjects in treatment E and agents in treatment O, followed by agents is treatment T.
The pairwise comparison of these frequencies yields 10 Hypotheses.
For SMs, our model yields the following order for the frequency of cooperative choices after a cooperative choice by the FM: The frequency is highest for agents in treatments T, followed by agents in treatment and subjects in treatment E, followed by principals in treatment O, followed by principals is treatment T.
The pairwise comparison of these frequencies yields 10 Hypotheses.
