This paper analyzes the job-to-job transitions of workers in the United States. I propose a new method of correcting the time-aggregation bias. The bias-corrected series from 1996 to 2011 reveals a procyclical pattern of job-to-job transition and a large decline since the beginning of the 2000s....

This paper formulates Rosenberg's (1982) "learning by using" as a stochastic process. The producer of machines learns from the experience of users. Due to this learning, the quality of machines improves over time. It turns out that the process of this improvement approximately takes an...

We study a political economy model of entry barriers. Each period the policymaker determines whether to impose a high barrier on entry, and the special interest groups try to influence the policymaker's decision. Entry is accompanied by creative destruction— when many new firms enter, old...

Since the end of the Great Recession in mid-2009, the unemployment rate has recovered slowly, falling by only one percentage point from its peak. We find that the lackluster labor market recovery can be traced in large part to weakness in aggregate demand; only a small part seems attributable to...

We provide a set of comparable estimates for the rates of inflow to and outflow fromunemployment using publicly available data for fourteen OECD economies. We thendevise a method to decompose changes in unemployment into contributions accountedfor by changes in inflow and outflow rates for cases...

The negative relationship between the unemployment rate and the job openings rate, known as the Beveridge curve, has been relatively stable in the U.S. over the last decade. Since the summer of 2009, in spite of firms reporting more job openings, the U.S. unemployment rate has not declined in...

The U.S. unemployment rate has remained stubbornly high since the 2007-2009 recessionleading many to conclude that structural, rather than cyclical, factors are to blame. Relying on astandard job search and matching framework and empirical evidence from a wide array of labormarket indicators, we...

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...
