Worth Your Weight: Experimental Evidence on the Benefits of Obesity in Low-Income Countries
通过乌干达坎帕拉的实验，发现肥胖被视为财富信号而非健康或美貌，能帮助低收入者获得更多贷款，其效果相当于借款人自报收入提高60%以上。
I study the economic value of obesity—a status symbol in poor countries associated with raised health risks. Randomizing decision-makers in Kampala, Uganda to view weight-manipulated portraits, I find that obesity is perceived as a reliable signal of wealth but not of beauty or health. Thus, leveraging a real-stakes experiment involving professional loan officers, I show that being obese facilitates access to credit. The large obesity premium, comparable to raising borrower self-reported earnings by over 60 percent, is driven by asymmetric information and drops significantly when providing more financial information. Notably, obesity benefits and wealth-signaling value are commonly overestimated, suggesting market distortions.
