Accounting for Mismatch Unemployment
研究了美国过去35年因错配导致的失业，提出核算框架估计各摩擦因素的贡献，发现工作流动障碍是主因，工人流动障碍次之，工资设定摩擦影响很小。
Abstract We investigate unemployment due to mismatch in the United States over the past three and a half decades. We propose an accounting framework that allows us to estimate the contribution of each of the frictions that generated labor market mismatch. Barriers to job mobility account for the largest part of mismatch unemployment, with a smaller role for barriers to worker mobility. We find little contribution of wage-setting frictions to mismatch.
