临时加薪对劳动力供给的影响：来自随机现场实验的证据
Labor Supply among Homeless Street-Paper Sellers: Evidence from a Randomized Wage Increase
AI总结：
研究通过随机对照试验检验临时加薪对劳动力供给的影响，发现工人销售更多报纸并延长工作时间，与以往间歇性劳动力供给研究结果形成对比。
摘要：
我们进行了一项预注册的随机对照试验，以检验在瑞典街头报纸销售者中收入目标对劳动力供给决策的影响。与大多数工人不同，这些销售者自行决定工作时间，并面临严重的流动性约束和收入波动。受试者在一期期间每售出一份报纸获得25%的奖金，模拟了收入潜力的增加。与标准劳动力供给理论一致，他们销售了更多的报纸，并在我们的衡量标准下工作更长时间，休假更少。这些发现与以往关于跨期劳动力供给的研究形成对比，后者发现替代效应较小。
英文摘要：
We conduct a pre-registered randomized controlled trial to test for income targeting in labor-supply decisions among sellers of a Swedish street paper. Unlike most workers, these sellers choose their own hours and often face severe liquidity constraints and volatile incomes. Treated individuals received a 25 percent bonus per copy sold via Swish, the mobile payment system that accounts for roughly 80 percent of sales, for the duration of an issue, simulating an increase in earnings potential. Consistent with standard labor-supply theory, they sold more papers and, by our measures, worked longer hours and took fewer days off. These findings contrast with studies on intertemporal labor supply that find small substitution effects.
