均衡失业的标准理论，即莫滕森-皮萨里德斯搜索和匹配模型，无法解释其两个核心要素失业和职位空缺的商业周期波动幅度。修改模型，使工资的现值对当前的劳动力市场状况不敏感，将失业率和职位空缺的波动放大了一个数量级，显著提高了模型的性能。尽管如此，这种刚性工资的福利后果是微不足道的。Robert Shimer芝加哥大学经济系1126 East 59 Street芝加哥，IL 60637和NBER shimer@uchicago.edu
The standard theory of equilibrium unemployment, the Mortensen-Pissarides search and matching model, cannot explain the magnitude of the business cycle fluctuations in two of its central elements, unemployment and vacancies. Modifying the model to make the present value of wages unresponsive to current labor market conditions amplifies fluctuations in unemployment and vacancies by an order of magnitude, significantly improving the performance of the model. Despite this, the welfare consequences of such rigid wages is negligible. Robert Shimer University of Chicago Department of Economics 1126 East 59 Street Chicago, IL 60637 and NBER shimer@uchicago.edu
