Temperature’s Toll on Decision-Making
利用印度尼西亚数据，研究发现高温天气会暂时增加非理性选择和不耐烦，但不影响风险决策，且主要通过夜间温度降低睡眠质量影响次日认知，对贫困家庭影响最大。
Abstract Does temperature affect decision-making abilities and rationality? Using Indonesian data, we estimate how risky choices, impatience and rational choice violations vary with exposure to temperature. We show that hot weather temporarily increases rational choice violations and impatience, but does not affect risk-related decisions. These effects are primarily driven by nighttime rather than daytime temperatures. We provide suggestive evidence that the mechanism behind these effects is decreased sleep quality, affecting cognition the following day, particularly math skills. These skills are critical for rational and utility-maximising decision-making. Effects are largest for economically disadvantaged households and in areas with low rates of air-conditioning.
