ECIN Replication Package for "Evidence on quality spillovers from speed enhancing policies in the workplace"

This package includes the code to replicate all tables and figures in the manuscript. The data for this project were shared with the authors under a nondisclosure agreement and are not included, however we have included a data dictionary that describes the variables needed to reproduce our analysis. We encourage researchers interested replicating the analysis to reach out to the first author with their request - the firm that provided the data is often willing to share the data for research and teaching purposes. Abstract: Empirical researchers often consider a single determinant of labor productivity: speed. This paper asks whether they are neglecting spillovers on output quality. Using high-frequency data on the speed and quality of strawberry harvesters’ work, we offer novel evidence that two distinct workplace policies associated with increases in worker speed lead to similar decreases in the quality of their work. We find that both peer speed and wage changes boost worker speed and lower output quality; 10 percent increases in speed are associated with reductions in quality on the order of 1.5 to 1.7 percent.

摘要：实证研究者往往仅将单一因素视作劳动生产率的决定变量：作业速度。本文旨在探究这类研究是否忽略了产出质量层面的溢出效应。本研究利用草莓采摘工人作业速度与作业质量的高频数据，提供了全新的实证证据：两种与提升工人作业速度相关的差异化职场政策，均会导致其作业产出质量出现类似程度的下降。我们发现，同伴作业速度提升与薪酬调整均能加快工人作业速度，但同时降低了产出质量；作业速度每提升10%，产出质量将下降1.5%至1.7%左右。
