Why inflation may be worse than you think it is

"And I was on the New Jersey Turnpike, and I went through rest stops. And I noticed little things that were off," Cole says. Stores had spotty hours. Napkin, utensil and condiment dispensers were empty. Fast-food restaurants weren't fast. He could see Help Wanted signs everywhere. "The rest stops were struggling to keep up the same level of service that they had before."
On his way back from Vermont, he stayed at a hotel in Poughkeepsie, N.Y. The morning after his stay, he woke up to a "sad and pitiful" breakfast that consisted of a plastic-wrapped, mass-produced pastry, prepackaged Raisin Bran and lukewarm milk. The hotel was now skimping on its hot-breakfast buffet as well as maid service for guests who stayed for more than one night. This, Cole realized, was happening across the entire economy — and he began to think the government wasn't fully capturing the decline of quality in official statistics.
Cole was formerly a senior economist at the Joint Economic Committee of the U.S. Congress, where he used to advise Sen. Mike Lee, R-Utah, and write official economic reports. These days he's a writer at Full Stack Economics. For most of his economics career, he says, he had believed that official government statistics actually made inflation seem worse than it really was. He had thought they didn't fully capture improvements in the quality of products and services when quantifying changes in prices.
For example, a couple of decades ago, you had to fork over a lot of money to buy physical albums if you were a music lover. Now you can use Spotify and listen to basically every album ever recorded in history for free or a low monthly fee. Some products, like electric skateboards, didn't even exist in the recent past. The government tries to capture such innovations and product improvements with a process called "hedonic quality adjustment."
But Cole believed that the government, while accounting for quality improvements, still failed to capture how much better products and services were getting. He didn't believe it was some sort of Illuminati conspiracy of Satan-worshipping pedophiles juicing the statistics. It's just super-hard to systematically account for changes in quality when measuring changes in prices. How do you gauge the priceless improvements to our lives brought about by things like Google's search algorithm, the Onewheel electric skateboard or baguette slippers?
Mismeasuring inflation has important implications. For example, it's common to hear people argue that the real, or inflation-adjusted, wage of the typical American worker has stagnated in recent decades. But if the government has been overstating inflation in its statistics, this means American workers' paychecks actually go further and living standards have gotten better than official statistics say.
