Instant coffee mix and Nike Air Max footwear are all in. Bottled water and high-end Burberry trench coats are out. Welcome to America’s consumer economy in the coronavirus health crisis. It is completely different than anything that Americans have ever experienced. “Everything we knew about supply and demand, we can…throw out…because consumer behavior has changed completely,” said Piotr Dworczak. He is an assistant professor of economics at Northwestern University in Illinois. Reuters news agency examined a wide mix of goods and products to show how the COVID-19 crisis has changed consumer behavior for everything from clothing to food. These changes have given some businesses the power to raise prices or, at least, stop lowering prices. Business experts say all of this can be linked to one change: working from home. Over a very short period, a consumer-driven economy with predictable work and home spending changed completely. Rising demand for some products, as well as supply-chain problems, has pushed prices up. American consumers are now spending a lot more than they did a year ago on coffee, eggs, and cheese, the Reuters study found. The study was based on the latest pricing information from the Nielson Company and other data-gathering businesses. Demand and prices have increased for more costly items, such as Nike Air Max sneakers or a Louis Vuitton handbag. Economists explain this by saying that many people have more money right now because they are unable to buy things at stores or eat in restaurants.
