英文文献摘要：
We use a directed search model to develop estimation procedures for the identification of worker and firm rankings from labor market data. These methods allow for a general specification of production complementarities and the possibility that higher ranked workers are not more productive in all firms. We also offer conditions for a positive/negative assortative matching that incorporate the possibility of a stochastic job ladder with on-the-job search. Numerical simulations relate the implications of the model to the implications of fixed effect regressions and give further insights into the performance of our estimation procedures. Finally, we evaluate evidence for Denmark using our methods and we show that workers are highly sorted and that higher type workers are less productive than lower type workers while employed in lower type jobs.

我们使用一个定向搜索模型来开发估计程序来识别工人和企业排名从劳动力市场数据。这些方法考虑到生产互补性的一般规范，以及在所有公司中，级别较高的工人并非效率更高的可能性。我们还为正/负选型匹配提供了条件，该匹配包含了随机工作阶梯与在职搜索的可能性。数值模拟将模型的含义与固定效应回归的含义联系起来，并进一步深入了解我们的估计程序的性能。最后，我们使用我们的方法对丹麦的证据进行了评估，结果表明，在从事低类型工作时，高类型工人的工作效率比低类型工人低。
