Factors Affecting the Timing of Purchasing of Butter, Margarine, and Blends: A Competing Goods Analysis
利用美国住户面板数据，通过事件史分析研究黄油、人造黄油及混合产品之间的购买转换行为，发现价格、历史购买、季节性和家庭特征影响产品转换概率。
Abstract The purchase dynamics of a subset of food fats and oils are investigated 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 occasions. We find that price, previous purchases, seasonality, and household size and composition affect product‐switching probability.
