This paper studies the design of group-buying mechanisms in a two-period game where cohorts of consumers arrive at a deal and make sign-up decisions sequentially. A firm can adopt either a sequential mechanism where the firm discloses to second-period arrivals the number of sign-ups accumulated...

We analyze a general model in which, at each echelon of the supply process, an arbitrary number of firms compete, offering one or multiple products to some or all of the firms at the next or possibly subsequent echelons or directly to the end consumer. At each echelon, the offered products are...

We consider an infinite-horizon dynamic matching problem where the agents on one side, say supply side, are long-lived, and those on the other, say demand side, are impatient and will get lost if unmatched upon arrival. The agents on either side are vertically differentiated with a high- or...

We study two privacy protection mechanisms motivated by emerging privacy regulations, limited retention and self-protection, in the context of data-driven (personalized) pricing. Limited retention refers to the removal of private data from a firm's database, and self-protection refers to a...

The on-demand delivery platforms for food and grocery have grown rapidly. One claimed benefit of those platforms is the potential to optimize courier routing by sharing couriers among many vendors, such as restaurants or grocery stores. However, it is puzzling to observe that the largest...

We consider a two-sided market competition problem where two platforms compete in both supply and demand sides. We examine a variety of competition modes and study the impact of precommitment on the equilibrium outcomes. By comparing three types of competitions: simultaneous price and wage...

We analyze a general but parsimonious price competition model for an oligopoly in which each firm offers any number of products. The demand volumes are general piecewise affine functions of the full price vector, generated as the "regular" extension of a base set of affine functions. The model...

Operations management has the tradition of coming from and going back to real-life applications. It deals with the management of the process of matching supply with demand. The emerging business process in a sharing economy or an innovative marketplace calls for active management. We take a...

Motivated by the emerging sharing economy, we study an on-demand matching platform that crowdsources a service from independent suppliers and sells it to customers. The platform offers a wage to the supply side and charges a price to the demand side. We consider a set of market conditions, under...

Vertical mergers within a multi-echelon market result in equilibrium price changes, for wholesalers and retailers, alike. They may also impact the product variety that is available to the consumer, i.e., the equilibrium product assortment sold in the market. In this paper, we consider the...
