Funding Public Goods with Lotteries: Experimental Evidence
通过实验室实验，检验了风险中性预期效用最大化者参与彩票资助公共品的模型，发现彩票比自愿捐款更能提高公共品供给，且彩票购买受固定奖金大小和公共品回报率影响。
Why do individuals participate in charitable gambling activities? We conduct a laboratory investigation of a model that predicts risk-neutral expected utility maximizers will participate in lotteries when they recognize that lotteries are being used to finance public goods. As predicted by the model, we find that public goods provision is higher when financed by lottery proceeds than when financed by voluntary contributions. We also find support for other comparative static predictions of the model. In particular we find that ticket purchases vary with the size of the fixed prize and with the return from the public good: lotteries with large prizes are more effective, and ticket purchases drop dramatically when the public good is not valued by subjects.
