Losing Prosociality in the Quest for Talent? Sorting, Selection, and Productivity in the Delivery of Public Services
在赞比亚全国医疗岗位招聘中嵌入田野实验，发现提供职业发展机会虽吸引较少亲社会的申请者，但仅对低才能者存在此权衡；高才能边际申请者同样亲社会且被录用后绩效更优，使儿童营养不良率下降25%。
We embed a field experiment in a nationwide recruitment drive for a new health care position in Zambia to test whether career benefits attract talent at the expense of prosocial motivation. In line with common wisdom, offering career opportunities attracts less prosocial applicants. However, the trade-off exists only at low levels of talent; the marginal applicants in treatment are more talented and equally prosocial. These are hired, and perform better at every step of the causal chain: they provide more inputs, increase facility utilization, and improve health outcomes including a 25 percent decrease in child malnutrition.
