Promotion and Fast Food Demand
研究快餐促销对市场需求和餐厅市场份额的影响，使用加拿大消费者面板数据估计离散/连续模型，发现促销主要增加总需求，对市场份额影响较小。
Abstract Many believe that fast food promotion is a significant cause of the obesity epidemic in North America. Industry members argue that promotion only reallocates brand shares and does not increase overall demand. We study the effect of fast food promotion on market share and total demand by estimating a discrete / continuous model of fast food restaurant choice and food expenditure that explicitly accounts for both spatial and temporal determinants of demand. Estimates are obtained using a unique panel of Canadian fast food consumers. The results show that promotion primarily increases demand and has a smaller effect on restaurant market shares.
