Multi-Task Agents and Incentives: The Case of Teaching and Research for University Professors
利用自然实验研究加强研究激励对大学教师教学和研究绩效的影响，发现教授会将精力从教学转向研究，且更严格的研究要求导致低研究能力的教师离职，从而对平均教学效果产生不确定影响。
Abstract This paper exploits a natural experiment to study the effects of providing stronger research incentives to faculty members on universities’ average teaching and research performance. The results indicate that professors are induced to reallocate effort from teaching towards research. Moreover, tighter research requirements affect the faculty composition, as they lead lower-research-ability professors to leave. Given the estimated positive correlation between teaching and research ability, those who leave are also characterized by lower teaching ability. The average effect on teaching for the university is therefore ambiguous, as positive composition effects countervail effort substitution.
