A TEST BETWEEN STOCK‐FLOW MATCHING AND THE RANDOM MATCHING FUNCTION APPROACH*
在控制时间聚合偏差的情况下，检验了标准随机匹配函数方法与股票流量匹配方法，发现匹配流量与职位空缺流入的相关性高于随机匹配的预测，数据支持股票流量匹配。
This article tests between the standard “random matching function” approach and “stock‐flow” matching while controlling for temporal aggregation bias. Consistent with previous empirical work, the random matching function fits the matching data reasonably well. But match flows are more highly correlated with vacancy inflows than is consistent with the random matching approach. Instead the data support stock‐flow matching, where unemployed workers match directly with suitable new vacancies as such vacancies come on to the market.
