Worker-firm screening and the business cycle
构建了一个包含工人和企业双向筛选的均衡模型，解释职位空缺与就业的联动，并复现了美国经济周期中劳动力市场的波动，同时为2008年后贝弗里奇曲线的移动提供了理论解释。
To understand the co-movement of vacancies and employment, an equilibrium model with two-sided screening is developed. On one side of the market, both employed and unemployed workers can evaluate multiple job openings simultaneously and decide which ones to apply for. On the other side, firms assess multiple applicants and choose their preferred candidates. This model is calibrated to reflect the U.S. economy. Consistent with data, the model generates significant volatility in vacancies, unemployment, and labor market flows over the business cycle. Moreover, differences in the search behaviors of employed and unemployed workers offer a theoretical explanation for the shift in the Beveridge curve observed after the 2008 recession.
