Uncertainty still remains as to the cause of the UK’s dramatic productivity puzzle that began during the Great Financial Crisis. Occupational mismatch has been implicated as driving up to two thirds of it. However, obtaining the high quality time series data for vacancies by job occupation that are required to measure occupational mismatch is a significant challenge. We confront this issue by using a weighted dataset of 15 million job adverts posted online that cover most of the post-crisis period and that enable us to test whether occupational mismatch still stands up as an explanation for the UK productivity puzzle. We find little evidence that it does, mainly because, relative to the data used in similar analysis by Patterson et al. (2016), our vacancy data imply greater heterogeneity in occupational matching frictions, a key determinant of the optimal distribution of labour across job types.

英国的生产力难题主要是由职业不匹配造成的吗?职位空缺大数据分析

英国在大金融危机期间开始出现戏剧性的生产力难题,其原因仍然存在不确定性。职业不匹配被认为是导致其中三分之二的原因。然而,获得衡量职业不匹配所需的职位空缺的高质量时间序列数据是一项重大挑战。我们通过使用在线发布的 1500 万个招聘广告的加权数据集来解决这个问题,这些数据涵盖了危机后的大部分时间,并使我们能够测试职业不匹配是否仍然可以作为英国生产力难题的解释。我们发现几乎没有证据表明它确实如此,主要是因为相对于 Patterson 等人在类似分析中使用的数据。(2016),我们的空缺数据意味着职业匹配摩擦的异质性更大,
