Retaining customers is a central concern in many industries, including IT markets, where churn rates—the rate at which subscribers to a service discontinue their subscriptions—are high. A new study in the INFORMS journal Marketing Science by researchers from Carnegie Mellon University tested a strategy to help a telecommunications firm manage churn. Contacting not only customers but also their friends helped reduce the customers’ propensity to discontinue their ties to the company.

Sorin Sorescu of Mays Business School at Texas A&M University discusses his recent study in the INFORMS journal Marketing Science that provides an in-depth analysis of major innovations and stock market bubbles from 1825 through 2000 and found some very distinctive patterns in the occurrence of bubbles over 175 years. 

A new study in the INFORMS journal Management Science has sought to address the challenges of kidney exchange and introduced the concept of "failure-aware" algorithmic matching to improve success rates.

New research has found a way to identify extremists, such as those associated with the terrorist group ISIS, by monitoring their social media accounts, and can identify them even before they post threatening content.

A new study in the INFORMS journal Management Science shows how to improve the success rate of an innovative kidney matching process called kidney exchange. The enhancement centers on a new concept called ‘failure-aware’ matching that takes pre-transplant compatibility failures into account probabilistically. Depending somewhat on the exact setting, the method can roughly double the number of transplants.
