室友问题的实验结果
Experimental results on the roommate problem
摘要
We use laboratory experiments to analyze decentralized decision-making in one-sided matching markets. We find that subjects tend to make decisions in line with most theoretical models, as their offering and accepting decisions are mainly guided by the objective of improving upon the status quo. In consequence, markets move towards satisfying blocking pairs making the number of remaining blocking pairs diminish and the aggregate payoffs increase over time. Overall, the theoretical solutions of absorbing sets and stable matchings to the roommate problem are supported by the experimental results. However, not all matchings in an absorbing set have the same power of attraction in the experimental laboratory. The theoretical property of P-stability refines absorbing sets as predictors of final outcomes.

摘要 我们通过实验室实验分析单边匹配市场中的分散决策。研究发现，受试者的决策行为与多数理论模型一致，其提议与接受决策主要受改善现状这一目标驱动。因此，市场会逐步消除阻碍配对，使剩余阻碍配对数量随时间递减，总收益随之增长。总体而言，室友问题中吸收集与稳定匹配的理论解得到了实验结果的验证。然而，实验室中吸收集内的不同匹配并非具有同等吸引力。理论上的P稳定性性质可进一步将吸收集精炼为最终结果的预测指标。
