Job losses during the Great Recession were concentrated among middle-skill workers, the same group that over the long run has suffered the most from automation and international trade. How might long-run occupational polarization be related to cyclical changes in middle-skill employment? We find...

A model of the labour market under firing restrictions and endogenous quits is constructed. It is shown that in the spirit of Blanchard and Summers (1988), the model can generate multiple equilibria, with a low-quits/high-unemployment equilibrium coexisting with a high-quits/low-unemployment...

We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...

The transition from centrally planned to market economy involves a process of massive occupational change that has been largely neglected in the literature. This paper investigates this process using data from the 1995 Estonian Labour Force Survey. We find that between 35 and 50 percent of wage...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

An advantage of collective wage agreement is that search and business-stealing externalities can be internalized. A disadvantage is that it takes more time before an optimal allocation is reached because more productive firms (for a particular worker type) can no longer signal this by posting...

The paper analyses complementarities among a variety of labour market policies. It shows: (a) that a wide range of labour market institutions (e.g. unemployment benefits, job security legislation and payroll taxes) have complementary effects on unemployment; and thus (b) that policies aimed at...

Microeconomic flexibility, by facilitating the process of creative-destruction, is at the core of economic growth in modern market economies. The main reason for why this process is not infinitely fast, is the presence of adjustment costs, some of them technological, other institutional. Chief...

This paper surveys the use of search and matching models in macroeconomics. It outlines the standard model, discusses its extensions, presents alternative formulations, considers the empirical evidence, and studies applications to macroeconomic questions such as business cycles, growth, and...
