摘要：We study incentive alignment for the coordination of humanitarian operations. Transportation is the second-largest overhead cost (after personnel) for international humanitarian organizations (IHOs). Yet, the management of IHO vehicle fleets faces obstacles to reach efficiency, due to a structural conflict between the incentives of an IHO's individual program (which prioritize prompt service and minimal program cost) and the IHO's central headquarters (which on top of the objective of the prog...

摘要：In this paper, we consider the problem in which a firm offers a portfolio of products (agricultural seeds) to multiple customer segments comprising farmers under aggressive fill-rate constraints, and some, but not all, customers will accept a substitute to their preferred choice. This business situation is not adequately represented by traditional inventory-management models, where a firm initiates a substitution based on its monetary considerations. By exploiting some recent results on polyhe...

摘要：We study the problem of dynamic assortment personalization with large, heterogeneous populations and wide arrays of products, and demonstrate the importance of structural priors for effective, efficient large-scale personalization. Assortment personalization is the problem of choosing, for each individual (type), a best assortment of products, ads, or other offerings (items) so as to maximize revenue. This problem is central to revenue management in e-commerce and online advertising where both...

摘要：We consider the problem of dynamic pricing in the presence of patient consumers. We call a consumer patient if she is willing to wait a certain number of periods for a lower price and will purchase as soon as the price is equal to or below her valuation. We allow for arbitrary joint distributions of patience levels and valuations. We propose an efficient dynamic programming algorithm for finding optimal pricing policies. We find numerically that optimal policies can take the form of incomplete...

摘要：In classical newsvendor games, vendors collaborate to serve their aggregate demand whose joint distribution is assumed known with certainty. We investigate a new class of newsvendor games with ambiguity in the joint demand distributions, which is represented by a Frechet class of distributions with some, possibly overlapping, marginal information. To model this new class of games, we use ideas from distributionally robust optimization to handle distributional ambiguity and study the robust new...

摘要：We consider an infinite-horizon lost-sales inventory model where the supply takes positive lead times and is a random function of the order quantity (e.g., random yield/capacity). The optimal policy for this model is computationally intractable, and no heuristic has been proposed in the literature. In this paper, we focus on a simple class of constant-order policies (COPs) that place the same order in every period regardless of the system state. Under some assumptions on the random supply func...

摘要：Passes are prepaid packages of multiple units of goods or services with flexible consumption times. They may take a variety of forms such as commuter passes in transportation, capped quotas in telecommunications, or memberships in health or beauty clubs. We consider a monopolist selling products or services to strategic customers by dynamically pricing passes in conjunction with individual items. The strategic behavior is captured by a dynamic choice model that endogenizes strategic purchase, ...

摘要：Pricing over multiple periods under forward-looking, strategic consumer purchasing behavior has received significant recent research attention; however, whether consumers actually benefit from this behavior and would voluntarily choose to be strategic has not been previously considered. We explore this question by developing a model of endogenous time preferences, consistent with microeconomic theories of boundedly rational intertemporal decision making, in which consumers choose to become str...

摘要：As self-interested individuals (agents) make decisions over time, they utilize information revealed by other agents in the past and produce information that may help agents in the future. This phenomenon is common in a wide range of scenarios in the Internet economy, as well as in medical decisions. Each agent would like to exploit: select the best action given the current information, but would prefer the previous agents to explore: try out various alternatives to collect information. A socia...

摘要：Naor's celebrated paper studies customer decisions in an observable M/M/1 queue in which joining-customers utility is linearly decreasing with the joining position. Naor derives the optimal threshold strategies for the individuals, social planner, and monopolist and proves that the monopoly optimal threshold is (weakly) smaller than the socially optimal threshold, which is (weakly) smaller than the individually optimal one. Studies show, based on numerical observations and/or ad hoc proof tech...
