Stated preferences for public provision of services: Experimental evidence from Latin America
通过调查实验研究六个拉美国家居民对教育和医疗公私提供方式的偏好，发现服务质量是选择的主要驱动因素，收入影响较小，机构信任降低转向私立的概率但不影响支付意愿。
We study how individuals in six Latin American countries value public versus private provision of education and healthcare using a survey experiment. Respondents were randomly assigned to vignettes that vary income, service quality, and provider type. Reported service quality is the main driver of choices: the probability of selecting a private provider roughly doubles when reported quality of the public option falls from 80 to 20 percent, while income has a smaller effect. Higher institutional trust lowers the likelihood of switching to private providers but does not affect willingness to pay once individuals choose private provision. • Perceived service quality is the main driver of private take-up in education and healthcare. • Income effects on private demand are smaller and less systematic than quality effects. • Higher institutional trust reduces exit from public services but not willingness to pay.
