Model-free clustering of an objective multi-round economic exchange game.
A) Depiction of Multi-Round Trust Task. A ten round task in which two players, an investor and a trustee, undergo repeated interactions. Adapted from previous publications [6], [7], [16], [20]. B&C) Our Approach. Following [23], we cluster investor-trustee dyads based on a regression of previous choices in the trust game. Specifically, we predict ratios of investment it in round t as a polynomial of past rounds of investment and return. The number of clusters, order of polynomial, and number of rounds back on which to base this dependence are all taken as free parameters in the model.
