Recent research has emphasized firm heterogeneity as a source of comparative advantage. Combining this approach with labor market frictions and worker heterogeneity provides a framework for studying the impact of trade on unemployment and inequality. This paper reviews this approach and reports...

This paper develops an algorithm for analyzing discrete events, such as labor market transitions, when some of these transitions are spurious because of measurement errors. Our algorithm extends the standard multinomial logit model, although our basic approach could be used with other stochastic...

We develop an empirical search-matching model which is suitable for analyzing the wage, employment and welfare impact of regulation in a labor market with heterogeneous workers and jobs. To achieve this we develop an equilibrium model of wage determination and employment which extends the...

This paper studies the optimal redistribution of income inequality in a model with search and matching frictions in the labor market. We study this problem in the context of a directed search model of the labor market populated by homogeneous workers and heterogeneous firms. The optimal...

The recent experience of Washington State provides a natural setting to examine the effects of the unemployment insurance payroll tax on wages, employment, claims and denials. During the 13 year period from 1972 through 1984, all employers in Washington paid the same unemployment insurance (UI)...

In this paper we theoretically and empirically examine the common, but previously unexamined, case of a firm-varying tax which is used to finance a fringe benefit. While we use data from the experience-rated unemployment insurance (UI) system, it is important to realize that differential...

This paper considers both theoretical quest ions and empirical measures of the effects of various policies of income and payroll taxation on labor supply. It emphasizes deadweight loss as the correct criterion of taxation evaluation, rather than merely output effects. Distributional issues are...

In this study the social security earnings test is shown to have a significant effect empirically on the labor supply of retirement aged men. A rich data file from the Social Security Administration containing accurate benefit information provides a cross- section sample of 65-70 year old...

Under the standard competitive model, a tax change affecting workers with highly inelastic labor supply, will lower earnings by the entire nominal employer share of the tax increase. If wages play a motivational role but the market still clears, the range of possible outcomes is broader but...
