Abstract

Cerina et al. (2023) affirm greater polarization of occupations between high- and low-skilled labor in large cities relative to small cities. The authors attribute differential rates of employment growth by occupation types to skill-biased technological change alongside consumption spillovers. They find a smaller role for differential total factor productivity gains in tradable sectors and extreme-skill complementarity in production. We computationally reproduce their results, reconstruct the authors' data cleaning and harmonization procedures, and test the broader replicability of the results. We find the results support for the internal validity of Cerina et al. (2023)'s results and broaden the external validity of the analysis.

空间极化。Cerina等人的复制研究（The Economic Journal, 2023）

Cerina等人（2023）确认，相对于小城市，大城市的高技能劳动力和低技能劳动力之间的职业两极分化更大。作者将不同职业类型的就业增长率差异归因于技能偏向的技术变革以及消费溢出效应。他们发现，贸易部门的全要素生产率差异和生产中的极端技能互补性的作用较小。我们计算重现他们的结果，重建作者的数据清洗和协调程序，并测试结果的更广泛的可复制性。我们发现结果支持Cerina et al.（2023）的结果的内部效度，并拓宽了分析的外部效度。

期刊介绍： The Journal of Applied Econometrics is an international journal published bi-monthly, plus 1 additional issue (total 7 issues). It aims to publish articles of high quality dealing with the application of existing as well as new econometric techniques to a wide variety of problems in economics and related subjects, covering topics in measurement, estimation, testing, forecasting, and policy analysis. The emphasis is on the careful and rigorous application of econometric techniques and the appropriate interpretation of the results. The economic content of the articles is stressed. A special feature of the Journal is its emphasis on the replicability of results by other researchers. To achieve this aim, authors are expected to make available a complete set of the data used as well as any specialised computer programs employed through a readily accessible medium, preferably in a machine-readable form. The use of microcomputers in applied research and transferability of data is emphasised. The Journal also features occasional sections of short papers re-evaluating previously published papers. The intention of the Journal of Applied Econometrics is to provide an outlet for innovative, quantitative research in economics which cuts across areas of specialisation, involves transferable techniques, and is easily replicable by other researchers. Contributions that introduce statistical methods that are applicable to a variety of economic problems are actively encouraged. The Journal also aims to publish review and survey articles that make recent developments in the field of theoretical and applied econometrics more readily accessible to applied economists in general.
