Land Tenure Differences and Adoption of Agri-Environmental Practices: Evidence from Benin
使用多项内生处理效应模型和倾向得分匹配，评估贝宁小农户土地产权对采用农业环境实践的影响，发现自有地块的采用强度显著高于借入、租入或分成地块。
This article uses a multinomial endogenous treatment effects model in combination with propensity score matching techniques to evaluate the impact of land tenure on the adoption of agri-environmental practices by smallholder farmers in Benin. We rely on a unique and detailed cross-sectional plot-level dataset that covers a random sample of 2800 smallholder farmers and 4233 plots. The results indicate that land tenure arrangement significantly influences farmers’ decision to invest in agri-environmental practices. The intensity of the adoption of agri-environmental practices is consistently higher on owned plots than borrowed, rented or sharecropped plots. We found strong evidence that the hypothesis of selectivity bias cannot be rejected. Although estimates of the adoption gap between plot owners and borrowers are larger when using the matched sample, the results are broadly consistent across specifications.
