报告内容摘要

  

  

报告内容:

Market size,  measured by the number of people who are interested in the products from the  same category, may be highly influenced by the management strategy of  assortment planning and pricing in some scenarios. This effect is referred to  as market expansion. In this paper, we incorporate the market expansion effects  into consumer choice models and investigate assortment and pricing problems.  In particular, we take the widely used multinomial logit model as a showcase  to examine the market expansion effects on assortment planning and pricing,  and also propose an alternating-optimization expectation-maximization method,  which separates the estimations of consumer choice behavior and the market  expansion effects, to calibrate the new model. Our empirical study on  synthetic and real data sets shows the efficiency of our estimation method and  the importance of incorporating the market expansion effects into consumer  choice models. Failure to account for the market expansion effects may lead  to substantial losses in demand estimation and operations management.
