尼日利亚推出了一项电子代金券肥料补贴计划，将代金券直接分发到受益者的手机上，通过将土地使用从粗放型转变为集约型，以提高农业生产率和粮食安全。通过使用2012年和2014年水稻种植家庭的面板数据，并应用家庭固定效应方法和逆概率加权方法，我们评估了电子代金券计划是否以及在多大程度上增加了水稻产量的化肥使用量。我们没有发现该计划导致更高化肥使用量的证据。这是因为民营化肥市场活跃的研究区域存在较强的挤出效应。这一发现表明，引入一种潜在的创新设备并不足以促进农业生产和粮食安全。
Nigeria introduced an e-voucher fertilizer subsidy program that distributes vouchers directly to a beneficiary’s mobile phone for enhancing agricultural productivity and food security by changing land use from extensive to intensive farming. By using panel data on rice-growing households in 2012 and 2014 and applying a household fixed effects approach and inverse probability weighting methods, we assess whether and how much the e-voucher program increases fertilizer application on rice production. We do not find evidence that the program results in higher fertilizer application. This is because there is a strong crowding-out effect in the study areas in which the private fertilizer market is active. This finding suggests that introducing a potentially innovative device is not sufficient to boost agricultural production and food security.
