Two key issues in the literature on female labor supply are: (1) if persistence in employment status is due to unobserved heterogeneity or state dependence, and (2) if fertility is exogenous to labor supply. Until recently, the consensus was that unobserved heterogeneity is very important, and...

This paper uses micro panel data to examine differences in the cyclical variability of employment, hours, and real wages for skilled and unskilled workers. Contrary to conventional wisdom, we find that, at the aggregate level, skilled and unskilled workers are subject to essentially the same...

In this paper, we use micro panel data to examine the effects of oil price changes on employment and real wages, at the aggregate and industry levels. We also measure differences in the employment and wage responses for workers differentiated on the basis of skill level. We find that oil price...

We provide evidence of advantageous selection in the Medigap insurance market and analyze its sources. Conditional on controls for Medigap prices, those with Medigap spend, on average, $4,000 less on medical care than those without. But if we condition on health, those with Medigap spend $2,000...

The allocation of children’s time among different activities may be important for cognitive and noncognitive development. Here, we exploit time use diaries from the Longitudinal Study of Australian Children to study the effects of time allocation. By doing so, we characterize the trade-off...

Using confidential firm-level data from the Bureau of Economic Analysis (BEA) on activities of U.S. multinational corporations (MNCs) and their Canadian affiliates, we study the dramatic growth of intra-firm and arm's-length U.S.-Canada trade over the 1984-95 period. We find that decisions to...

The response of aggregate labor supply to various changes in the economic environment is central to many economic issues, especially the optimal design of tax policies. This paper surveys recent work that uses structural models and micro data to evaluate the size of this response. Whereas the...

We evaluate the effect of child care versus maternal time inputs on child cognitive development using single mothers from the NLSY79. To deal with nonrandom selection of children into child care, we exploit the exogenous variation in welfare policy rules facing single mothers. In particular, the...

Using data from the NLSY79, we structurally estimate a dynamic model of the life cycle decisions of young women. The women make sequential joint decisions about school attendance, work, marriage, fertility, and welfare participation. We use the model to perform counterfactual simulations...

This article develops a simulation estimation algorithm that is particularly useful for estimating dynamic panel data models with unobserved endogenous state variables. Repeated sampling experiments on dynamic probit models with serially correlated errors indicate the estimator has good small...
