We consider decentralized platforms facilitating many-to-many matches between two sides of a marketplace. In the absence of direct matching, inefficiency in market outcomes can easily arise. For instance, popular supply agents may garner many units from the demand side, while other supply units...

Following the work by White (1980ab; 1982) it is common in empirical work in economics to report standard errors that are robust against general misspecification. In a regression setting these standard errors are valid for the parameter that in the population minimizes the squared difference between...

Inpatient ward beds play a central role in hospital operations. To better facilitate coordination of care, the beds are usually grouped into different specialized units, with each unit designated to serve patients in certain primary specialties. However, inpatient wards are often associated with...

The operations management discipline has made substantial progress developing analytical models to help firms make tactical and strategic decisions (e.g., inventory control, assortment planning). The application of these models to real contexts requires several inputs, such as an estimate of the...

In this paper, we study the problem of identifying network effects in contagion processes and present an application to the propagation of influenza in the United States. In particular, using data on the evolution of infections over time, the travel intensity between states as well as...

Problem definition: We study how online platforms can leverage the behavioral considerations of their users to improve their assortment decisions. Motivated by our collaboration with a dating company, we study how a platform should select the assortments to show to each user in each period to...

Because a hospital is an interconnected, interdependent network of care units, allocating resources — beds, nurses, and improvement initiatives — to one unit to reduce its congestion may have spillover effects on other units. As such, to identify the bottleneck unit and improve access to...

Service systems' behavior can be affected by multiple factors. In the case of intensive care units (ICUs), which admit patients from four primary loci (the emergency department (ED), scheduled patients, planned transfers from other ICUs, and unplanned transfers), it is known that admission rates...
