Abstract

This article evaluates the short-term impacts of a fruit fly integrated pest management program in Peru. Exploiting arbitrary variation in the program’s intervention borders, we use a geographical regression discontinuity design to identify the program’s effects on agricultural outcomes. Pre-treatment balance tests show that producer and farm-level pre-treatment characteristics evolve smoothly at the intervention border. Results indicate that farmers within treated areas improved pest knowledge and are more likely to implement prevention and control practices. Also, they increased fruit production and sales. Our findings are confirmed by placebo tests and are robust to alternative regression discontinuity bandwidths and polynomials.

扫除苍蝇：根除果蝇计划的证据

摘要

本文评估了秘鲁果蝇综合有害生物管理计划的短期影响。利用程序干预边界的任意变化，我们使用地理回归不连续性设计来确定程序对农业成果的影响。预处理平衡测试表明，生产者和农场一级的预处理特征在干预边界处平稳发展。结果表明，治疗区内的农民提高了对有害生物的了解，并更有可能实施预防和控制措施。此外，他们增加了水果的生产和销售。我们的发现已通过安慰剂测试证实，并且对替代回归不连续性带宽和多项式具有鲁棒性。
