自设目标的提醒对生产率的影响

We examine how reminders for self-set goals influence productivity by analyzing data from 10,187 volunteer agricultural extension workers in Rwanda. We elicited workers’ goals and experimentally varied their salience through text reminders. Due to unforeseen logistical delays, approximately half of the treatment group received reminders after completing their tasks. We find that goal reminders received during the regular working period increased a productivity index by 0.08 standard deviations, while reminders sent late had no effect. Further analysis of heterogeneity by goal ambition quartiles reveals an inverted U-shaped relationship: reminders are effective for goals in the second and third quartiles, but ineffective for low or excessively high goals. These results suggest that workers who set ambitious yet realistic goals are more likely to respond to reminders and increase productivity, consistent with prior evidence on externally set goals.
