Do Management Interventions Last? Evidence from India
九年后回访印度织布企业，发现实验组约一半管理实践被放弃，但与对照组仍有显著差距，表明有效干预有持久影响，但关键员工流失是实践下降的主因。
We revisited Indian weaving firms nine years after a randomized experiment that changed their management practices. While about half of the practices adopted in the original experimental plants had been dropped, there was still a large and significant gap in practices between the treatment and control plants, suggesting lasting impacts of effective management interventions. Few practices had spread across the firms in the study, but many had spread within firms. Managerial turnover and the lack of director time were two of the most cited reasons for the drop in management practices, highlighting the importance of key employees.
