SOCIAL DYNAMICS OF OBESITY
构建了一个包含食品价格下降、内生社会体重规范与异质性代谢的模型，解释美国女性体重分布变化，并成功预测了1976-2000年间的肥胖率增长。
We explain the recent increases in obesity in the United States with a model involving falling food prices, endogenous social body weight norms, and heterogeneous human metabolism. Calibrating an analytical choice model to American women in the 30‐ to 60‐yr‐old age bracket, we compare the predicted weight distributions to National Health and Nutrition Examination survey data spanning (intermittently) the years 1976–2000. The model, the first to describe explicitly complete weight distribution dynamics for this group, predicts average weights and obesity rates with considerable accuracy and captures a significant portion of the recent growth in upper quantile weights.
