BALTIMORE, MD, May 13, 2025 – As communities across the United States continue to confront the devastating toll of mass shootings, new research reveals a staggering economic dimension to these tragedies. A study published in the INFORMS journal Marketing Science finds that mass shootings cause an estimated $27 billion in annual lost revenue for U.S. retailers driven by sharp declines in foot traffic, reduced transaction volume and long-term store closures.
BALTIMORE, MD, May 13, 2025 – Researchers who took a close look at loosened concealed carry laws between 2010 and 2017 have found that “Shall Issue” regulations, which remove local authority discretion on the issuance of concealed carry gun permits, contribute to a significant increase in handgun purchases. At the same time, the researchers found that in states that adopted “Permitless Carry” policies, there was no noticeable change in gun purchases.
The time has come: REAL ID will finally be implemented in less than one week, about 20 years after it was initially proposed.

“How might we use artificial intelligence and big data to help scientists advance our understanding?” That understanding, presumably, would be used to accelerate the creation of the universal flu vaccine, a topic that is explored in a new editorial from INFORMS member Eva Lee.
As a study by researchers from the City University of Hong Kong, the Georgia Institute of Technology and Carnegie Mellon University, which has been published in the INFORMS journal Management Science, has shown, delaying the ebook's output does not have a positive impact on sales of the paper edition. In addition, it has a subsequent negative impact on e-book sales.
New research in the INFORMS journal Management Science found that delaying the sale of the e-version of a new book does not lead to increased print sales, and can result in significantly fewer e-book sales (a nearly 50 percent decrease) once the digital version is made available.
According to a study in the INFORMS journal Marketing Science, co-authored by Yanwen Wang of the University of British Columbia in Vancouver, Michael Lewis of Emory University in Atlanta and David A. Schweidel of Georgetown University in Washington, D.C., negative advertising is effective in influencing voters — but significantly more so when the attacking candidates themselves run the ads.
In a new editorial, Eva Lee, professor at the Georgia Institute of Technology and INFORMS Fellow, discusses the need for a universal flu vaccine, and how operations research and analytics hold the key to creating it.
