Data for: The own-wage elasticity of labor demand: A meta-regression analysis

Abstract of associated article: The own-wage elasticity of labor demand is a key parameter in empirical research and policy analysis. However, despite extensive research, estimates of labor demand elasticities are subject to considerable heterogeneity. In this paper, we explore various dimensions of this heterogeneity by means of a comprehensive meta-regression analysis, building on information from 151 different studies containing 1334 estimates in total. Our results show that heterogeneity in the estimates of the elasticity is natural to a considerable extent: the magnitude of the elasticity depends on the theoretical model applied and features of the workforce. Moreover, we find that labor demand has become more elastic over time, and is particularly elastic in countries with low levels of employment protection legislation. Furthermore, we find heterogeneity due to the empirical specification of the labor demand model, characteristics of the dataset and publication bias.关联文章摘要：劳动需求的自身工资弹性（own-wage elasticity of labor demand）是实证研究与政策分析领域的关键参数。尽管已有大量相关研究，但劳动需求弹性的估算结果仍存在显著异质性。本文基于涵盖151项独立研究、总计1334个弹性估算值的文献信息，通过全面的元回归分析，系统探究了该异质性的多维度来源。研究结果表明，弹性估算值的异质性在相当程度上具有其自然合理性：弹性的大小取决于所采用的理论模型与劳动力群体特征。此外，研究发现劳动需求弹性随时间推移逐渐增强，且在就业保护立法水平较低的国家中表现得尤为突出。同时，本研究还识别出异质性的其他来源，包括劳动需求模型的实证设定方式、数据集自身特征以及发表偏倚。
