We analyze a periodic review stochastic inventory model with T periods and I items. At the beginning of each period, the inventory position of each item can be adjusted by placing an order or by salvaging some of the inventory. There is a limited capacity for the total inventory held at the end...

Problem definition. Motivated by the debate around drivers' welfare in on-demand transportation, we propose a framework to evaluate current practices and also possible alternatives. We study a setting in which riders seek drivers and a platform facilitates such matches over the course of the...

We consider an online assortment optimization problem where we have n substitutable products with fixed reusable capacities c1,...,cn. In each period t, a user with some preferences (potentially adversarially chosen) arrives to the seller's platform who offers a subset of products St, from the...

We develop a model of Cournot competition between capacity-constrained firms that sell a single good to multiple regions. We provide a novel characterization for the unique equilibrium allocation of the good across regions and design an algorithm to compute it. We show that a reduction in...

We consider a dynamic pricing problem for a large inventory of substitutable products over a finite planning horizon. Customers arrive sequentially and in each period a single customer randomly chooses at most one unit of a product in-stock. Purchase probabilities depend on product prices and...

We provide an economic model of an e-commerce retail platform (e.g., Amazon) that offers a fulfillment service (e.g., "Fulfilled By Amazon") to merchants that sell on its platform. We demonstrate that the introduction of such a service generates distributional effects for the platform...
