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.

If you had to teach remotely and money were no object, what kind of home studio would you build? You might find inspiration atop a Tennessee garage. That’s where a business school professor commandeered his kids’ playroom and spent more than $25,000 on audio and video gear to create a state-of-the-art Zoom classroom for the pandemic era.
As Gov. Mike Parson campaigns across Missouri to defend his widely criticized handling of the COVID-19 pandemic and asks voters to grant him a full term, he has promoted an eye-catching statistic that suggests his administration has tamed the deadly virus. “In April, when our death rate was at 8 percent – close to 8 percent – today, it is at 0.7,” Parson said at last Friday’s gubernatorial debate. He also cited the data while speaking to reporters last week.
The most celebrated theory in all of economics, the so-called First Welfare Theorem, says that, provided there is perfect competition and perfect information, free markets allocate resources resources efficiently. In other words, it says the father of economics Adam Smith was right, that the “invisible hand” of the market works in the best interest of society. Often the conditions are not met, and much of modern economics is about how to improve the otherwise suboptimal outcomes delivered by unfettered markets.
CATONSVILLE, MD, October 16, 2020 – Telemedicine has become more common given the current global pandemic. COVID-19 has limited doctor’s office and hospital visits to ensure safety for everyone.
