The Psychological Lives of the Poor
提出穷人依赖的基本心理能力（带宽）可能因营养不良、饮酒或睡眠不足等因素而受损，进而影响判断、偏好和决策，甚至可能波及生产力和效用，为理解贫困的成因与后果提供新视角。
All individuals rely on a fundamental set of mental capacities and functions, or bandwidth, in their economic and non-economic lives. Yet, many factors associated with poverty, such as malnutrition, alcohol consumption, or sleep deprivation, may tax this capacity. Previous research has demonstrated that such taxes often significantly alter judgments, preferences, and decision-making. A more suggestive but growing body of evidence points toward potential effects on productivity and utility. Considering the lives of the poor through the lens of bandwidth may improve our understanding of potential causes and consequences of poverty.
