Supply chain redux: Empty grocery store shelves return

Grocery store shelves have been emptier than usual lately, similar to the beginning of the pandemic when many products were out of stock.

Experts say this time around there are multiple factors playing a role in the shortages, including panic-buying, weather, the fast-spreading omicron variant causing labor shortages, shipping delays and more.

San Diego State University marketing and business lecturer Miro Copic joined KPBS Midday Edition on Tuesday to talk about the causes of the current shortages and the rising cost of food.

"The supply chain disruptions that kind of started this summer and carried over through the holiday shopping period are still with us. Obviously in the winter, winter weather is not good, and we're seeing a lot of disruptive storms, not just in the United States but in countries around the world that grow important crops like coffee, so coffee prices for example might be increased substantially," Copic said. "The omicron variant of the coronavirus has been devastating, not only for the sheer numbers but because it requires people to be absent, whether on food production lines or at the grocery stores, so it really strains the labor pool. Clearly, the labor shortages due to the Great Resignation has been a factor in hollowing out employees at the supermarket level."

Copic said lifestyle changes during the pandemic like eating out less led to more supply and demand issues, which play a role in inflation.

"Americans for the last two years have been eating at home a lot more, which puts a lot of strain on the supply chain. For example, the average weekly grocery bill in 2019 was about $114. It was $160 during the first year of the pandemic, and it was over $145 last year," Copic said. "That's a little bit less than the first year of the pandemic where more people just stayed home, but still, it's a 27% increase in the amount of groceries people are buying. If you have supply chain disruptions, that means those shelves become bare much faster. There's a whole issue of psychology around well, if things are missing, 'I need to buy more things so I can store them for the future.'"

He said when there are fewer products available, grocers can charge more because consumers will pay a premium for what is available.

Copic said grocery stores will start to look more stocked as omicron cases start to lessen, and harsh weather starts to decline in March and April.
