Fairness through the Lens of Cooperative Game Theory : An Experimental Approach

We experimentally investigate how impartial observers allocate money to agents whose complementarity and substitutability determine the surplus each group can achieve. Analyzing the data through the lens of axioms and solutions from cooperative-game theory, a one-parameter model (mixing equal split and Shapley value) arises as a parsimonious description of the data. Three treatments establish the robustness of this qualitative conclusion, while also illustrating how context may impact the parameter estimate
