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.

An individual American taxpayer spends roughly 13 hours and $240 out-of-pocket costs just to prepare and file one annual tax return, according to one 2022 study—an estimated 1.15 billion hours collectively spent on tax preparation.
What are the new rules for tipping? Businesses that never seemed to ask for a tip before — like grocery stores, self-checkout machines and fast food restaurants — are now asking for one these days.
Critical infrastructure sectors are becoming increasingly complex and interdependent and so, too, are the physical and socioeconomic landscapes in which they operate. This in turn has increased the possibility of disruptions and subsequent compounding disruptions. Climate change adds an additional layer of uncertainty and disruption to these evolving interconnected networks. And, for the power grid, this shifting threat landscape is exacerbated by increased demand from electrification, decarbonization, population growth, and an overall increase in reliance on electricity. Climate change is also affecting energy usage patterns. For example, Texas has seen spikes in energy demand and intense strain on the power grid from both unexpected cold snaps and intense heat waves.
