The Dynamics of Individuals' Fat Consumption
构建了一个动态模型，研究消费者如何通过调整脂肪摄入来控制累积脂肪水平，并利用家庭消费数据估计需求系统，发现消费者会主动调整但非即时，高教育家庭调整更快，累积脂肪增加时转向乳制品和白肉。
Consumers are increasingly aware of the link between their lifestyle choices and the risk of noncommunicable diseases. A dynamic approach incorporating this linkage in food demand is developed, where consumers maximize utility over time by choosing fat intake to control their cumulative fat level. The resulting dynamic indirect utility function and household data on meat, fish, and dairy consumption are used to estimate a censored demand system. Results show that consumers consciously adjust, but not instantaneously, their cumulative fat level. Highly educated households have a faster rate of adjustment of cumulative fat. When cumulative fat level increases, consumers shift to dairy or white meat from red meat products.
