The effect of earned endowments and tangible money on charitable giving
通过实验研究参与者亲手接触现金（实物货币）是否影响其作为独裁者向慈善机构捐赠或索取的行为，发现实物禀赋减少但未消除捐赠，且赚取的钱在实物条件下显著降低捐赠，而在非实物条件下无显著影响。
Abstract We design and conduct an experiment to determine whether participants’ physical handling of money affects their choices as a dictator to take from or give to charity. We run separate treatments for house money and earned endowments. We report three results. First, tangible endowments reduce, but do not eliminate, charitable giving. Second, participants are more likely to take in the tangible treatments than to the intangible treatments. Finally, we do not observe a consistent earned money effect. With tangible endowments, earned money significantly reduces giving; with intangible endowments, we find that earned money has no significant effect on giving. This contrasts with prior studies that found that earning one’s endowment reduced giving in standard Dictator Games (i.e. those with anonymous other subjects as recipients). Our results suggest that the nature of the recipient and the action set are important factors for making decisions in the laboratory.
