Cooperation in Experimental Games of Strategic Complements and Substitutes
通过实验室实验，研究在有限重复两人博弈中，战略替代性和战略互补性如何影响合作倾向，发现战略互补时合作显著更多。
We conduct a laboratory experiment aimed at examining whether strategic substitutability and strategic complementarity have an impact on the tendency to cooperate in finitely repeated two-player games with a Pareto-inefficient Nash equilibrium. We find that there is significantly more cooperation when actions exhibit strategic complementarities than in the case of strategic substitutes. The difference is to some extent driven by a difference in the speed with which some pairs reach stable full cooperation, but mainly by differences in choices of pairs that do not succeed in reaching full cooperation.
