Bw. Gould, FACTORS AFFECTING THE TIMING OF PURCHASING OF BUTTER, MARGARINE, AND BLENDS - A COMPETING GOODS ANALYSIS, American journal of agricultural economics, 80(4), 1998, pp. 793-805
The purchase dynamics of a subset of food fats and oils are investigat
ed using event-history analysis applied to a panel of U.S. households.
The consumer behavior examined is the switching between purchases of
butter, margarine, and butter/margarine blends across purchase occasio
ns. We find that price, previous purchases, seasonality, and household
size and composition affect product-switching probability.
