If It Pays, It Stays: Can Agribusiness Internalize the Benefits of Malaria Control?
研究评估了疟疾控制干预（发放蚊帐）对赞比亚棉花种植户的农业产出影响，发现尽管健康改善显著，但农业企业并未从棉花交付中获益，与近期关于疟疾控制提升农业生产力的证据不一致。
Might a malaria control intervention entail agricultural effects that allow a commercial agribusiness to offset its costs? The randomized allocation of 39,936 insecticide-treated mosquito nets among 81,597 smallholder cotton farming households in 1,507 clusters helps evaluate this in the context of Zambia's cotton outgrowing industry. But despite large health impacts on treated households, no impact on cotton deliveries to the agribusiness is detected. With some caveats, the results tend to strike a discord with recent evidence on the agricultural productivity effects of malaria control.
