Evidence on quality spillovers from speed enhancing policies in the workplace
利用草莓采摘工的高频数据，研究发现同事速度提升和工资变化都会加快工人速度，但导致工作质量下降约1.5-1.7%。
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 1.5–1.7 percent.
