News — We all remember 2020. At the grocery store, toilet paper shelves were empty. Cleaning supplies and disinfectants were treasured finds. Rattled consumers, concerned that they would run out of essential items, swiftly stockpiled products until they disappeared from shelves. In the media, it was referred to as “panic buying.”

Rensselaer Polytechnic Institute’s , William H. Hart Chair Professor of Civil and Environmental Engineering and director of the Center for Infrastructure, Transportation, and the Environment (CITE), contends that this was a misnomer.

“Disaster-related buying behaviors or DRBBs is a more accurate phrase than panic buying,” Holguin-Veras said. “Panic refers to extreme fear that causes someone to act irrationally, which negates the possibility to reason with these individuals to change their purchasing behaviors.”

Instead, , Holguín-Veras and team collected surveys in dozens of countries and found that, in the U.S., the top three themes were: precaution (25.79%), the anticipation of needs (22.63%) to avoid the possibility of regret if they didn’t make the purchases (16.39%), and their interpretation of the actions of others, or social cues (13.44%).

They found that the key to altering consumer behavior to maintain adequate supply levels is trusted change agents, or TCAs. TCAs refer to the representatives of groups active in disaster perceived to be knowledgeable and trustworthy such as the Red Cross, national/state/local emergency responders, firefighters, and national/state/local health officials, that can reach large numbers of people, understand the need to influence the individuals that enact “panic buying,” and are willing to act. A whopping 89% of people said that they would limit their purchases if asked by a TCA.

A typical food distribution center has two days worth of supplies. The research team found in their survey that, of the households that engaged in DRBBs, 80% increased their inventories by a week and a half!

“Managing demand is essential because modern supply chains rarely have the ability to quickly increase production and distribution of essential items,” said Holguin-Veras.

Peoples’ objectives in DRBBs ran the gamut. First, self-preservation was a primary concern. Second, altruism factored in as consumers wanted to provide for their loved ones and their communities. Third, opportunism reared its head, as people tried to cash in on opportunities to sell hard-to-find items at a premium. With this in mind, a one-size-fits-all approach will not work.

“Managing DRBBs requires effective public-private-humanitarian collaboration,” said Holguin-Veras. “The public sector has the legal authority to intervene when needed, the private sector has control over the access and supplies, and the humanitarian sector has the deep community connections.”

The sectors must work together in preparation, response, and assessment. Building trust and relationships, monitoring events and identifying situations that could prompt DRBBs, and examining legal frameworks are priorities during the preparation phase. During response, demand should be managed by working with private- and humanitarian- sector representatives, TCAs should be engaged, opportunistic purchases should be controlled to foster equitable access, and rationing should be instituted if needed. Appeals for the donations of stockpiled supplies are another measure that can be taken. Finally, a comprehensive assessment would facilitate any needed improvements.

“Dr. Holguin-Veras’ work continues to enrich our understanding and ability to respond during disasters and emergencies,” said Shekhar Garde, dean of Rensselaer’s School of Engineering. “His work shows that for solving complex interconnected challenges, understanding of human factors is as important as technological solutions.  I hope that these findings will inform strategies to avoid supply shortages in the future.”

Holguin-Veras was joined in research by Rensselaer’s Sofía Pérez-Guzmán and Oriana Calderón, Trilce Encarnación of the University of Missouri-St. Louis, and Víctor Cantillo of the Universidad del Norte.
