摘要：

We develop a two-stage choice model with product unawareness and study assortment optimization and pricing problems under this choice model. Under the assumption that the utilities are independent and identically Gumbel-distributed, we derive a closed-form expression for the choice probabilities. For the assortment optimization problem, we find a revenue-ordered assortment is optimal for the niche product set but the assortment problem for the mainstream product set is NP-hard. Thus, we give a tight 1/2-approximation algorithm and devise a fully polynomial-time approximation scheme. For the joint assortment and pricing problem, we show that all products should be offered and the products in the same stage should be priced with the same revenue. We extend our analysis to the assortment optimization problem with mixed customers, advertisement costs and duopoly competition. The corresponding constant-factor algorithm or fully polynomial-time approximation scheme is provided. We also calibrate our choice model using a real data set on soft drinks and show that our model can outperform the standard MNL model in multiple criteria.
