We study contracts between a single retailer and multiple suppliers of two substitutable products, where suppliers have fixed capacities and present the retailer cost contracts for their supplies. After observing the contracts, the retailer decides how much capacity to purchase from each...

We present tight bounds and heuristics for personalized, multi-product pricing problems. Under mild conditions we show that offering a non-personalize price in the direction of a positive vector (factor) has a tight profit guarantee relative to optimal personalized pricing. An optimal...

A growing body of research suggests that an abundance of choices can lead to decision-making difficulties for consumers. Rather than maximizing utility, many consumers employ a satisficing decision-making approach, whereby they search for products sequentially until they find one that is...

Two-sided marketplaces have grown rapidly over recent years and are ubiquitous in daily life. One important challenge is to design the marketplace to support the sustainability and efficiency of the ecosystem. This paper investigates the roles of selling formats in a two-sided marketplace with...

We generalize the concept of K-convexity to an n-dimensional Euclidean space. The resulting concept of K-convexity is useful in addressing production and inventory problems where there are individual product setup costs and/or joint setup costs. We derive some basic properties of K-convex...

Dynamic pricing is designed to increase revenues or profits of the firm by adjusting prices in response to changes in the marginal value of capacity as described in Gallego and van Ryzin (1994). While thousands of papers have been written about dynamic pricing, this is to our knowledge the first...

A pervasive problem for retailers is to make assortment and inventory procurement decisions of substitutable products with the goal of maximizing expected profits over a pre-defined selling horizon. Multiple inventory replenishments are not allowed. This problem is challenging because of demand...

We consider two business models for a two-sided economy under uncertainty: dealership and marketplace. Although both business models can bridge the gap between demand and supply, it is not clear which model is better for the firm or for the consumers. We show that while the two models differ...
