In normal times, a boost in retail sales would be something to cheer. It suggests that consumers are spending, producers are producing, and plenty of resources exist to support it.
By normal times, I mean most of the past 40 years before three years ago. That’s because inflation at the time seemed manageable, running generally at about 2 percent per year. It never occurred to anyone that a boost in retail sales was nothing more than people spending more money on the same thing.
Retail sales are typically reported in nominal terms; that is, just the amounts. In times of high inflation, however, this creates an odd situation. People have to spend more on the same good or service on repeated buys. You know this now from personal experience. What used to cost $1 is now $1.50 or $2. If the government reported the new spending as great news, you might protest: “That is not progress, and it certainly is not good news.”
And yet, old habits die hard. Month after month, retail sales data are reported not in real terms but nominal ones. There are many features of government data today that deserve skepticism, but this one ranks up at the top. It is so brazenly misleading, and yet there is no official source out there that reports real retail sales.
This is odd because no agency would report gross domestic product (GDP) numbers without adjusting them for inflation. And yet, for retail sales, such adjustments are never made. Or, rather, you have to make the adjustment yourself.
My colleague E.J. Antoni is the great innovator here. He had the insight to adjust the sales by dollar depreciation. After all, if your weekly grocery bill went from $100 to $200, and then you had to start substituting cheaper products for more expensive ones, that would not be a good thing. And yet the agencies come along and say, "Hey look, sales are up."
Antoni does the calculation using conventional inflation data, which is widely underreporting the numbers. It mangles housing prices, does not report housing insurance prices or interest rates, and dramatically underplays inflation in goods such as cars, groceries, and much more. And yet that is the data we have. What does he end up with?
He wrote: “July advance retail sales estimate is 14.0 percent above Apr ’21, but down 3.0 percent in real terms over that same time—businesses are selling less stuff, but at much higher prices.”
