Tax Credits, Labor Supply, and Child Care
利用1986年NLSY数据，通过结构劳动供给模型分析美国儿童保育税收抵免对已婚有幼子女女性劳动供给的影响，发现补贴大幅增加劳动供给，且提高抵免比例比提高支出上限或改为可退还更有效。
We explore the impact of the child care tax credit in the U.S. income tax system on the labor supply decisions of married women with young children by incorporating the cost of child care into a structural labor supply model. Using data from the 1986 NLSY, we find that government subsidies to child care increase labor supply substantially. Our policy simulations show that an increase in the value of the child care tax credit (i.e., percent of expenditures subsidized) would have a much larger effect on labor supply than an increase in the annual expenditure limits of the subsidy or making the subsidy refundable. © 1997 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
