Measuring Labor Market Frictions: A Cross-Country Comparison
利用工作持续时间数据定义并估计劳动力市场摩擦，比较不同估计方法和数据类型，提出一种适用于加总持续时间数据的无条件推断方法，并量化了法国、美国、英国、德国和荷兰的搜索摩擦导致的垄断势力，考察了最低工资、失业救济和搜索摩擦的政策效应。
In this paper we define and estimate measures of labor market frictions using data on job durations. We compare different estimation methods and different types of data. We propose and apply an unconditional inference method that can be applied to aggregate duration data. It does not require wage data, it is invariant to the way in which wages are determined, and it allows workers to care about other job characteristics. The empirical analysis focuses on France, but we perform separate analyses for the United States of America, the United Kingdom, Germany, and the Netherlands. We quantify the monopsony power due to search frictions and we examine the policy effects of the minimum wage, unemployment benefits, and search frictions.
