Firms and workers predominately match via job postings, networks of personal contacts or the public employment agency, all of which help to ameliorate labor market frictions. In this paper we investigate the extent to which these search channels have differential effects on labor market...

I propose an equilibrium search and matching model with permanent worker heterogeneity, asymmetric information, and endogenous separations and study the dynamics of adverse selection in the labor market. The interaction between asymmetric information and endogenous separations leads to a...

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

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 decisions of firms on investment and hiring play a crucial role in business cycle fluctuations. This paper explores their dynamic behavior in the presence of frictions. It does so within a unified framework, stressing their mutual dependence and placing the emphasis on their joint,...

Despite its low unemployment rate, the recent shift in the Japanese Beveridge curveindicates increased labor mismatch. This paper quantifies the age, employment-type (fullor part-time), and occupational mismatch in the Japanese labor market following Sahinand others (2013). Between April 2000...

COVID-19 has exacerbated concerns about the rise of the robots and other automation technologies. This paper analyzes empirically the impact of past major pandemics on robot adoption and inequality. First, we find that pandemic events accelerate robot adoption, especially when the health impact...

The labor search and matching model plays a growing role in macroeconomic analysis. This paper provides a critical, selective survey of the literature. Four fundamental questions are explored: how are unemployment, job vacancies, and employment determined as equilibrium phenomena? What...

Why do some people become entrepreneurs, how do institutions affect this choice, and how does this affect the firm size distribution and aggregate productivity? This paper addresses this question using a matching model with occupational choice and heterogeneity in both ability as a worker and ex...

The youth unemployment rate in Korea stood at eight percent as of 2021. The expanded youth unemployment rate, however, reached 23 percent in that same year, indicating that at least one in every four or five young persons in Korea was struggling to find suitable work. Although the unemployment...
