Household Labor Supply and Welfare Participation in Sweden
用瑞典家庭数据估计了一个家庭劳动力供给模型，发现丈夫劳动供给缺乏弹性、妻子工资弹性为正，且交叉弹性接近零。
Using a sample of Swedish households, we estimate a household labor supply model assuming that preferences for consumption and leisure can be described by a direct translog utility function. The labor supply and welfare participation decisions are treated as a discrete choice problem, and we assume that these choices follow a simple conditional logit rule. In addition, we allow unobserved individual- specific effects to be correlated across alternatives. We assume that these unobserved effects are drawn from a discrete distribution, and the correlation across alternatives is modeled using factor-loading techniques. Classification error in hours is allowed for by using a multiplicative measurement error specification. The estimates from the structural model yield inelastic labor supply among husbands and positive wage elasticity for wives. Further, the cross elasticities are close to zero.
