随机控制实验:助推脱贫的现场干预研究

消除贫困是全世界新千年的首要目标。行为经济学家和发展经济学家正借助随机控制实验和助推技术在全球范围内帮助贫困者摆脱贫困。当前采用随机控制实验帮助贫困者克服行为偏差的助推行动主要表现在帮助贫困者改善当前物质条件和提升未来保障两个方面。随机控制实验和助推技术在国内的研究和实践也有效地帮助国内贫困农民提高了身心健康水平和经济收入。未来还需加强关于随机控制实验和助推技术的外部效度检验及两者的异同点方面的研究, 并结合脱贫的内生动力制定更加简单、高效、严谨的扶贫政策和项目。

Nudging in field interventions of anti-poverty based on randomized controlled trials

The eradication of poverty is a top priority for developing countries and the most important goal of the Millennium Development Goals all over the world. Behavioral economists and development economists are employing the randomized control trials and nudge techniques to help the poor get rid of poverty within the globe. The current nudge action that uses randomized control experiments to help poor people overcome behavioral deviations is mainly manifested in helping poor people improve their current material conditions and enhance future security. The research and practice of random control experiments and nudging technologies in China have also effectively helped poor farmers improve their physical and mental health, and economic income. In the future, it is necessary to strengthen the research on the external validity test of randomized control experiments and nudging techniques, the similarities and differences among them, and combine with the endogenous power of poverty alleviation to formulate more simple, efficient, and strict poverty alleviation policies and projects.
