The Estimation of a Joint Wage-Hours Labor Supply Model
修改了标准劳动供给模型，将工资内生化，并估计了联合工资-工时模型。通过离散点近似处理预算约束的非线性，发现预算约束确实非线性，工时对工资有二次影响，真实工资弹性更低，且模型比标准Tobit模型更好地拟合工时分布。
In this paper the standard cross-sectional static model of labor supply is modified to make the wage endogenous, and a joint wage-hours model is estimated. The econometric technique addresses the non-linearity of the budget constraint by approximating the constraint by a series of discrete points. The results show that the budget constraint is indeed nonlinear, that hours affect the wage quadratically, that true wage elasticities are lower as a result, and that the model fits the hours distribution much better than the standard Tobit model.
