This paper studies the optimal redistribution of income inequality caused by the presence of 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 homogenous workers and heterogeneous firms. The optimal...

This paper nests a continuous-time learning model Jovanovic (1984) into a directed on-the-job search framework. We prove that the socially efficient allocation is separable, i.e., the workers' value functions and optimal controls are independent of both the distribution of workers across their...

We argue that using wage data alone, it is virtually impossible to identify whether Assortative Matching between worker and firm types is positive or negative. In standard competitive matching models the wages are determined by the marginal contribution of a worker, and the marginal contribution...

In this paper, we present a unified treatment of and explanation for the evolution of wages and employment in the U.S. over the last 30 years. Specifically, we account for the pattern of changes in wage inequality, for the increased relative wage and employment of women, for the emergence of the...

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

What do we know about the economic consequences of labor market regulations? Few economic policy questions are as contentious as labor market regulations. The effects of minimum wages, collective bargaining provisions, and hiring/hiring restrictions generate heated debates in the U.S. and other...

We revisit the hypothesis that labor market fluctuations are driven by shocks to the discount rate. Using a model in which the UE and the EU rates are endogenous, we show that an increase in the discount rate leads to a decline in both the UE and the EU rates. In the data, though, the UE and EU...

The Affordable Care Act (ACA) is one of the most important reforms of the US health insurance system since the introduction of Medicare. Since employment is a main source of health insurance for the working age population in the United States, this sweeping health insurance reform also has...

We study the labor markets in China and the United States, the two largest economies in the world, by examining the evolution of their cross-sectional age-earnings profiles during the past thirty years. We find that, first, the peak age in the cross-sectional age-earnings profiles, which we...

We analyze the career profiles of Italian legislators in the post-war period. Using a unique, newly collected dataset that contains detailed information on all the politicians who have been elected to the Italian Parliament between 1948 and 2008, we address a number of important issues that...
