Sequential Fair Allocation With Replenishments: A Little Envy Goes An Exponentially Long Way
Chido Onyeze, Sean R. Sinclair, Chamsi Hssaine +1
We study the trade-off between envy and inefficiency in repeated resource allocation settings with stochastic replenishments, motivated by real-world systems such as food banks and…
On The Limited Cost of Consistency In Points-Based Rewards Programs
Chamsi Hssaine, Yichun Hu, Ciara Pike-Burke
Points-based rewards programs are a prevalent way to incentivize customer loyalty. In theory, the effective design of these programs is shaped by two important considerations. Cust…
Online Allocation of Throughput-Constrained Resources Using Proxy Assignments
Chamsi Hssaine, Huseyin Topaloglu, Garrett van Ryzin
We study a variation of the canonical online resource allocation problem in which resources are throughput, rather than budget, constrained. As in the classical setting, the decisi…
The Data-Driven Censored Newsvendor Problem
Chamsi Hssaine, Sean R. Sinclair
We study a censored variant of the data-driven newsvendor problem, where the decision-maker must select an ordering quantity that minimizes expected overage and underage costs base…
Price Competition Under Platform-Mediated Search: A Consider-Then-Choose Framework
Siddhartha Banerjee, Chamsi Hssaine, Vijay Kamble
We study the problem of predicting price equilibria on e-commerce platforms where sellers compete across multiple attributes (e.g., price, average rating, delivery speed). In these…
Online Fair Allocation of Perishable Resources
Siddhartha Banerjee, Chamsi Hssaine, Sean R. Sinclair
We consider a practically motivated variant of the canonical online fair allocation problem: a decision-maker has a budget of perishable resources to allocate over a fixed number o…
On the Power of Delayed Flexibility: Balls, Bins, and a Few Opaque Promotions
Daniel Freund, Chamsi Hssaine, Jiayu Kamessi Zhao
Effective load balancing lies at the heart of many applications in operations. Frequently tackled via the balls-into-bins paradigm, seminal results established the power of two cho…
Fair Incentives for Repeated Engagement
Daniel Freund, Chamsi Hssaine
We study a decision-maker's problem of finding optimal monetary incentive schemes for retention when faced with agents whose participation decisions (stochastically) depend on the…
Real-Time Approximate Routing for Smart Transit Systems
Siddhartha Banerjee, Chamsi Hssaine, Noémie Périvier +1
We study real-time routing policies in smart transit systems, where the platform has a combination of cars and high-capacity vehicles (e.g., buses or shuttles) and seeks to serve a…
Information Signal Design for Incentivizing Team Formation
Chamsi Hssaine, Siddhartha Banerjee
We study the use of Bayesian persuasion (i.e., strategic use of information disclosure/signaling) in endogenous team formation. This is an important consideration in settings such…
