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.

Recent egg price quotes are evaluated in a vector autoregression. The results indicate that empirical relationships observed over the period 1975-1976 differ from those observed over the period 1979-1982.
