NGOs and the Effectiveness of Interventions
结合印度分层实地实验和三重差分估计，发现当地发展非政府组织与目标社区的先前接触能使技术推广项目的有效性提高至少30%，揭示了实施者身份对项目效果的影响。
Abstract Programs implemented by nongovernmental organizations (NGOs) are often more effective than comparable efforts by other actors, yet relatively little is known about how implementer identity drives final outcomes. By combining a stratified field experiment in India with a triple-difference estimation strategy, we show that a local development NGO’s prior engagement with target communities increases the effectiveness of a technology promotion program implemented in these areas by at least 30%. This “NGO reputation effect” has implications for the generalizability and scalability of evidence from experimental research conducted with local implementation partners.
