| contents | An opaque product is a product for which only partial information is disclosed to the buyer at the time of purchase. Opaque products are common in sectors such as travel and online retail, where the car type or product color is hidden in the opaque product. Opaque products enable sellers to target customers who prefer a price discount in exchange for being flexible about the product they receive. In this paper, we integrate opaque products and traditional products together into the multinomial logit (MNL) choice model and study the associated price and assortment optimization problems. For the price optimization problem, we surprisingly show that uniform pricing is optimal which implies it has the same optimal pricing solution and value as the traditional MNL model. While adding an opaque product priced at the revenue-maximizing price may enhance revenue given arbitrary traditional product prices, this advantage disappears when all prices are optimized jointly. For the assortment optimization problem, we show that the revenue-maximizing assortment is nested-by-valuation for uniformly priced products. For non-uniformly priced cases, we propose a natural nested-by-revenue-and-valuation heuristic that performs extremely well in an extensive numerical study. |
