One of the most important long-run trends in the U.S. labor market is polarization, defined as the relative growth of employment in high-skill jobs (such as management and technical positions) and low-skill jobs (such as food-service and janitorial work) amid the concurrent decline in...

This paper measures the job-search responses to the COVID-19 pandemic using realtime data on vacancy postings and ad views on Sweden's largest online job board. First, the labour demand shock in Sweden is as large as in the US, and affects industries and occupations heterogeneously. Second, the...

This paper measures the job-search responses to the COVID-19 pandemic using realtime data on vacancy postings and job ad views on Sweden's largest online job board. First, new vacancy postings drop by 40%, similar to the US. Second, job seekers respond by searching less intensively, to the...

According to search-matching theory, the Beveridge curve slopes downward because vacancies are filled more quickly when unemployment is high. Using monthly panel data for local labour markets in Sweden we find no (or only weak) evidence that high unemployment makes it easier to fill vacancies....

I define occupations that are employed in more industries as "broader" occupations. I study the implications of broadness for mismatch of the unemployed and vacancies across occupations and industries. I empirically find that workers in broader occupations are better insured against...

We examine the matching process using monthly panel data for local labour markets in Sweden. We find that an increase in the number of vacancies has a very weak effect on the number of unemployed workers being hired: unemployed workers appear to be unable to compete for many available jobs....

Why do workers change occupations? This paper investigates occupational mobility and its determinants following a large unexpected shock (communism's collapse in 1989.) Our calculations show that from 1989 to 1995 between 35 and 50 percent of Estonian workers changed occupations (classified at...

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...

This paper studies the extent to which the cyclicality of gross and net occupational mobility shapes that of aggregate unemployment and its duration distribution. Using the SIPP, we document the relation between workers' (gross and net) occupational mobility and unemployment duration over the...
