As consumers are offered an ever-increasing number of options for almost every purchase decision in online retail, understanding the impact of assortment size on consumer choice decisions––especially on both search and purchase behavior––is critical. Our research speaks to this question...

With the increasing availability of data, the adoption of algorithms has become almost a necessity for businesses. Since algorithms often require human involvement, understanding how humans perceive algorithms is instrumental to the success of algorithm design in operations. In particular, the...

(1) Problem Definition: How to dynamically replenish inventory from two supply sources or shipping modes with general lead times. The fast source is more expensive than the slow source.(2) Academic/Practical Relevance: Dual sourcing provides supply chain flexibility to mitigate demand and supply...

This paper studies how service providers can design social interaction among participants and quantify the causal impact of that interaction on service quality. We focus on education and analyze whether encouraging social interaction among students improves learning outcomes in Massive Open...

Given an input graph Gin =(V,E_in), we consider the problem of designing a sparse subgraph G = (V, E) with E ⊆ E_in that supports a large matching after some nodes in V are randomly deleted. We study three families of sparse graph designs (namely, Clusters, Rings, and Erdős-Rényi graphs) and...
