摘要

利用孟加拉国8846块水稻种植地块的全国代表性横断面数据,我们分析了社会安全网计划(SSNPs)对水稻种植者生产力和效率的影响。本研究采用倾向得分匹配(PSM)方法来纠正可能由观察到的和未观察到的影响家庭参与SSNP决策的因素引起的自我选择偏差。分别估计了参与者和非参与者的随机前沿生产函数,以比较产量和技术效率。结果表明,除土地和肥料外,非参与者的所有投入的产出弹性都显著高于参与者。sssnp参与方的技术效率比非参与方高1.95%,前沿产量比非参与方高11.75%。对被处理作物的平均处理效应(ATET)也证实了ssnp的增产和增效作用,特别是在气候胁迫地区。该研究主张扩大ssp的覆盖范围,以提高气候脆弱地区边缘农民的效率。其他政策干预措施包括通过适当运作的土地市场、教育、提供扫盲培训和不同的生产投入来增加农民获得土地的机会。

Social safety nets and productivity outcomes: Evidence and implications for Bangladeshi rice growers

Using national representative cross-sectional data from 8846 rice growing plots in Bangladesh, we analyze the impact of social safety net programs (SSNPs) on rice farmers' productivity and efficiency. This study applied the propensity score matching (PSM) approach to correct the possible self-selection biases arising from observed and unobserved factors affecting a household's SSNP participation decisions. The stochastic frontier production function is estimated separately for participants and non-participants to compare yield and technical efficiency. Our results show that the output elasticities of all inputs except land and fertilizer are significantly higher for non-participants than participants. The SSNP participants are estimated to have 1.95% higher technical efficiency than the non-participants, while their frontier yield is 11.75% higher. The average treatment effect on treated (ATET) also confirms the yield and efficiency-enhancing role of SSNPs, particularly in climate-stressed areas. The study argues for widening the SSNP coverage to increase the marginal farmers' efficiency in climate-vulnerable areas. Other policy interventions include policies to increase farmers' access to land through the proper functioning land market, education, providing literacy training, and different production inputs.

期刊介绍: The Asian Economic Journal provides detailed coverage of a wide range of topics in economics relating to East Asia, including investigation of current research, international comparisons and country studies. It is a forum for debate amongst theorists, practitioners and researchers and publishes high-quality theoretical, empirical and policy orientated contributions. The Asian Economic Journal facilitates the exchange of information among researchers on a world-wide basis and offers a unique opportunity for economists to keep abreast of research on economics pertaining to East Asia.
