Unemployment insurance (UI) provides temporary income support to workers who have lost their jobs and are seeking reemployment. This paper reviews the origins of the federal-state UI system in the United States and outlines its principles and goals. It also describes the conditions for benefit...

The Patient Protection and Affordable Care Act expands Medicaid and in-troduces health insurance subsidies, thereby changing work incentives for single mothers. To undertake an ex ante policy evaluation of the employment effects of the PPACA, I structurally estimate a model of labor supply and...

This paper develops a model of unemployment fluctuations. The model keeps the architecture of the Barro and Grossman (1971) general disequilibrium model but replaces the disequilibrium framework on the labor and product markets by a matching framework. On the product and labor markets, both...

This study considers the relationship between temperature and occupational health. The results indicate that both high and low temperatures increase injury rates and that high temperatures have more severe adverse effects in warmer climates, which suggests that avoiding the adverse effects of...

This paper quantifies the extent to which the U.S. manufacturing labor market is characterized by employer market power and how such market power has changed over time. We find that the vast majority of U.S. manufacturing plants operate in a monopsonistic environment and, at least since the...

This paper proposes a novel strategy for identifying the effects of import competition on economic outcomes that avoids standard concerns related to the endogeneity of trade policy and provides a consistent measure of exposure to trade over time. Conditioning on the level of import tariffs, our...

We evaluate the effects of state-provided financial incentives for biotech companies, which are part of a growing trend of placed-based policies designed to spur innovation clusters. We estimate that the adoption of subsidies for biotech employers by a state raises the number of star biotech...

Two labor supply issues that have received substantial attention are the responsiveness of labor supply to wage changes and the imposition of labor supply constraints. Adjusting hours worked on a second job may be the practical and perhaps only available response to either event yet, most labor...

This paper examines the relationship between the cost of child care and the employment behavior of married and single mothers. The data used in this paper are from the 1987 SIPP, the first SIPP panel to utilize an improved probing of child care usage and expenditures. A primary contribution of...

According to the intertemporal-substitution hypothesis, which underlies the typical empirical real business cycle model, cyclical fluctuations in employment and hours of work are optimizing labor-supply responses to short-run aggregate demand shifts. We demonstrate that previous empirical...
