The Anatomy of the Extensive Margin Labor Supply Response*
利用瑞典1997年税制改革，估计已婚女性劳动参与弹性平均为0.13，并发现低收入群体中就业水平最低者的弹性是最高者的两倍。
Abstract We estimate how labor force participation among married women in Sweden responded to changing work incentives implied by a reform in the tax and transfer system in 1997. Using rich, population‐wide, administrative data, we estimate an average participation elasticity of 0.13, thereby adding to the scarce literature estimating participation elasticities using quasi‐experimental methods. We also highlight that estimated extensive margin responses necessarily are local to the observed equilibrium. Among low‐income earners, elasticities are twice as large in the group with the lowest employment level, compared with the group with the highest employment level.
