Cholesterol Information and Shell Egg Consumption
研究胆固醇信息（基于医学期刊文章构建的指数）如何影响美国带壳鸡蛋的人均消费，发现到1987年第一季度，胆固醇与心脏病关联的信息使消费下降了16%至25%，并改变了价格和收入弹性。
Abstract U.S. per capita shell egg consumption has declined steadily since 1955 despite a falling real price. This paper investigates how information about cholesterol, as measured by a newly constructed index based on medical journal articles, has affected U.S. demand for shell eggs. The results of a fixed coefficient model indicate that information on the links between cholesterol and heart disease had decreased per capita shell egg consumption by 16% to 25% by the first quarter of 1987. A simple changing coefficient model indicates that cholesterol information has changed shell eggs' own price and income elasticities, so that the 1955–87 falling egg price and rising income increased egg consumption less than they otherwise would have.
