Notes: The first column gives the relative frequency of efficient outcomes. The efficient outcome is a periphery-sponsored star where the core invests in four units and no periphery player invests. Mean earnings are denoted per subject in points per period. For mean net earnings we subtract the status rents. Standard errors of the means are computed using each group as an individual observation. The panels on the right give p-values for tests whether mean net earnings differ between treatments.
