The Effect of High-Performing Mentors on Junior Officer Promotion in the US Army
利用美国陆军行政数据和军官评估报告，研究发现高绩效导师能提升初级军官的早期晋升概率，且高质量指导时间越长效果越明显，但对高能力下属影响最大，而接触多位高绩效导师并无额外增益。
Military assignment mechanisms provide a unique opportunity to estimate the impact of high-performing mentors on job advancement of their subordinates. Combining US Army administrative data with officer evaluation reports, we find that high-performing mentors positively affect early junior officer promotion and that early promotion probabilities rise as the duration of the high-quality mentorship increases. These effects are largest for high-ability protégés. Junior officers who were exposed to multiple high-performing mentors did not experience an additional increase in promotion rates.
