本文提出了一个动态的体重理论，并发展其含义。我们认为，技术变革通过使家庭和市场生产更加久坐，并通过农业创新降低食品价格，从而导致体重增长。此外，我们还说明，虽然运动和食物摄入是互补的，但减少运动总是会提高最佳体重，增加食物摄入也是如此。我们还描述了体重如何随收入而变化，无论是在一个国家内，还是在不同的国家。在一个国家内，收入可能与体重呈倒U型关系，这是由于对食物的需求和对理想体重的需求的抵消作用。这可能对公共交通计划对体重的影响产生重要影响。然而，就各国而言，富裕国家的平均体重可能更高。最后，我们提出了描述性的实证证据，说明了倒U形的美国男性体重和收入之间的关系，并建议长期趋势的重要性，体重增加，这是一致的影响，广泛的技术变革。
This paper presents a dynamic theory of body weight and develops its implications. We argue that technological change has induced weight growth by making home- and market-production more sedentary and by lowering food prices through agricultural innovation. In addition, we illustrate that, while exercise and food intake are complements, reductions in exercise will always raise optimal body weight, as will increases in food intake. We also characterize how body weight varies with income, both within a country, and across countries. Within a country, income may have an inverted U-shaped relationship with body weight, due to the offsetting effects of the demand for food, and the demand for an ideal body weight. This can have important implications for the body weight impacts of public transfer programs. Across countries, however, mean weight is likely to be higher in richer countries. Finally, we present descriptive empirical evidence that illustrates the inverted U-shaped relationship between body weight and income in US males, and suggests the importance of secular trends in weight gain, which are consistent with the impacts of broad-based technological changes.
