In this paper, we present a unified framework for decision making under uncertainty. Our framework is based on the composite of two risk measures, where the inner risk measure accounts for the risk of decision given the exact distribution of uncertain model parameters, and the outer risk measure...

In this paper, we consider a new customer choice model which we call the single transition choice model. In this model, there is a universe of products and customers arrive at each product with a certain probability. If the arrived product is unavailable, then the seller can recommend a subset...

Should a seller make information about its products readily accessible to customers, so that customers do not have to incur any substantive cost — in terms of time and effort — to learn about those products? To help answer this question, we consider a monopolist selling two substitute...

In this paper, we introduce a consumer choice model in which each consumer's utility is affected by the purchase probabilities of his/her neighbors in a network. Such a consumer choice model is a general model to characterize consumer choice under network effect. We first characterize the choice...

We analyze the assortment optimization problem faced by a monopolistic firm selling n substitutable products in both store and online channels. In our problem, a subset of products (the assortment) are offered in store while all products are sold online. Compared to purchasing in store,...

Motivated by a research gap in modeling consumers' purchase behavior over multiple pages of a recommender system, we propose a mixed cascade model to describe consumers' decisions and study the corresponding assortment optimization and pricing problems. We first test the fitness of our proposed...
