The effect of cognitive function on the poor's economic performance: Evidence from Cambodian smallholder farmers
研究柬埔寨农村小农的认知功能水平能否解释其经济表现的差异，发现认知功能受损会导致经济表现陷入负反馈循环，部分农民因此难以摆脱贫困。
Abstract Despite manifold policy interventions, poverty still exists. Those most harshly affected are people living in rural areas of low‐income countries. A seminal strand in the literature presents a promising avenue for analyzing the lives of the poor by suggesting that poverty impedes cognitive function. However, the real‐world consequences of impeded cognitive function are yet to be discovered. We ask whether the level of cognitive function can help to explain the differences in economic performance of the poor. We conducted a field study in rural Cambodia using the well‐established Raven's Progressive Matrix to elicit cognitive function. Employing stochastic frontier analysis, we find that the level of cognitive function of poor smallholder farmers helps in explaining differences in economic performance. Our findings suggest that impeded cognitive function results in a negative economic performance feedback loop, which can be a reason why some farmers appear to be stuck in poverty while others manage to escape it.
