This paper develops and implements a semiparametric estimator for investigating, with panel data, the importance of human capital accumulation, non-separable preferences of females and child care costs on females life-cycle fertility and labor supply behaviors. It presents a model in which the...

This paper considers the problem of identifi…cation and estimation in panel-data sample-selection models with a binary selection rule when the latent equations contain possibly predetermined variables, lags of the dependent variables, and unobserved individual effects. The selection equation...

This paper formulates and estimates a dynamic model of labor supply, occupational sorting, human capital accumulation and discrimination to explain the narrowing gender earnings gap from 1968 to 1993. The paper proves the model is identified and develops a three-step estimation technique....

We develop a pure moral hazard model, and a closely related hybrid one, where there are both hidden actions and hidden information, to derive the restrictions from optimal contract theory that characterize set identification. In pure moral hazard models, the expected utility of managers is...
