[Problem Definition] We incorporate heterogeneous customer valuation and the strategic customer behavior in the classical economic order quantity (EOQ) setting. The seller incurs setup costs when replenishing inventory, and can set the prices differently over time and implement capacity...

Resale of used products may shrink the new-product market and create the cannibalization problem. This problem is exacerbated in the digital goods market because copies of digital goods can be perfect substitutes of the original. Many digital goods/service producers take advantage of technology...

We study the design of price mechanisms for communication network problems in which a user's utility depends on the amount of flow she sends through the network, and the congestion on each link depends on the total traffic flows over it. The price mechanisms are characterized by a set of axioms...

In this paper, we consider a model with a monopoly firm who sells social goods sequentially to a group of customers in a network. We show that, with symmetric social interactions, the optimal pricing under arbitrary launch sequence is independent of customers' network positions, the launch...

We study pricing strategies of competing firms that sell heterogeneous products to consumers in a social network. Goods are substitutes and there are network externalities between neighboring consumers. We show that there exists a unique subgame-perfect equilibrium where, in the first stage,...
