转移支付项目边际劳动供给响应模型：一个历史例证
A Model of the Marginal Labor Supply Response to Transfer Programs, with a Historical Illustration
摘要
We estimate the effects of welfare program participation on the labor supply of those who are on the margin of participation. We develop a local IV method that can semiparametrically estimate the shape of the marginal labor supply response curve as participation grows and declines. In an application to the historical AFDC program and using an instrument for program participation costs, we estimate a quadratic curve, rising and then falling as participation rates rise The average work disincentive is modest in size but there are some margins where effects are sizable and some where it is effectively zero.
中文摘要
我们估算了福利计划参与对处于参与边缘人群劳动供给的影响。我们开发了一种局部工具变量方法，能够半参数地估计随着参与率上升和下降时边际劳动供给响应曲线的形状。在应用于历史上的AFDC计划并使用一个针对参与成本的工具变量时，我们估计出一条二次曲线，该曲线随参与率上升先增后减。平均工作抑制效应规模适中，但在某些边际上效应显著，而在另一些边际上则几乎为零。
