Purpose

The aim of this paper is to analyze the effects of access to credit on maize productivity in Mali, by identifying the determinants of credit market participation and maize yield, and then estimating the impact of credit on maize yield.

Design/methodology/approach

This study analyzes the impact of credit on maize productivity using data from the World Bank 2014 Living Standards Measurement Survey (LSMS) on Mali, and the endogenous switching regression (ESR) model.

Findings

The results suggest a positive effect of credit on maize yield in Mali. Farm size, production shocks and the female gender exert negative effects on credit market participation, unlike education, intercropping with cotton, male family labor and fertilizer use which show positive effects. Farm size has a negative effect on maize yield, but both male family labor, and fertilizer use exert positive effects. Although the use of credit improves agricultural yields, the results show a greater potential effect for rationed producers, than credit users.

Research limitations/implications

These results suggest that implementing a credit strategy that allows those currently excluded from the credit market, to participate, could substantially increase productivity and maize production output in furtherance of the country's food security strategy. Gender-based targeting is needed to bridge the gender gap in access to credit.

Originality/value

As far as the authors are aware, this study is the first to explore the credit-farm productivity links in Mali, while addressing selection bias.

马里获得信贷和玉米生产力

目的

本文的目的是通过确定信贷市场参与和玉米产量的决定因素，然后估计信贷对玉米产量的影响，分析获得信贷对马里玉米生产力的影响。

设计/方法/方法

本研究使用世界银行 2014 年马里生活标准测量调查 (LSMS) 的数据和内生转换回归 (ESR) 模型分析信贷对玉米生产力的影响。

发现

结果表明信贷对马里的玉米产量有积极影响。农场规模、生产冲击和女性性别对信贷市场参与产生负面影响，不像教育、棉花间作、男性家庭劳动力和化肥使用显示出积极影响。农场规模对玉米产量有负面影响，但男性家庭劳动力和化肥使用都会产生积极影响。尽管信贷的使用提高了农业产量，但结果表明，对定量生产者的潜在影响比信贷使用者更大。

研究限制/影响

这些结果表明，实施一项允许目前被排除在信贷市场之外的人参与的信贷战略可以大大提高生产力和玉米产量，从而促进国家的粮食安全战略。需要基于性别的目标来弥合获得信贷方面的性别差距。

原创性/价值

据作者所知，这项研究是第一个探讨马里信用农场生产力联系的研究，同时解决了选择偏差。
