Fertilizer subsidies and private market participation: the case of Kano State, Nigeria
研究了尼日利亚卡诺州的化肥代金券项目对农民参与私人化肥市场的影响，发现补贴增加了农民参与私人市场的可能性和程度。
Abstract This article estimates the effect of a fertilizer voucher program on farmer participation in the private fertilizer market in Nigeria. Using a double‐hurdle model (to address corner solution challenges with estimating input demand) and a control function approach (to account for the endogeneity of subsidized fertilizer acquired), the study finds evidence that receiving subsidized fertilizer in Kano, Nigeria increased both the probability and extent of participation in the private fertilizer market. Findings demonstrate that under certain circumstances, e.g., where input dealers’ links to farmer are weak; there could be significant gains from the temporary use of voucher programs to strengthen such links.
