An Experiment on Risky Choice Amongst Households
通过实验研究多成人家庭的风险决策，发现联合决策比个人更规避风险，但同样存在预期效用理论的偏离。
A host of experiments have examined theories of risky choice using "individuals". However, many important economic decisions are taken within multi-adult "households". This paper reports on the first economic experiment designed to test theories of household choice. We use established couples and face them individually and jointly with decisions involving monetary payoffs. We find that joint choices typically are more risk averse than those made by individuals. Meanwhile, choices made by couples exhibit the same kinds of departures from expected utility theory (e.g. the common ratio and common consequence effects) as are regularly recorded with individuals.
