Want companies to lower their prices? Stop buying stuff from them.

This dynamic of how consumers adjust their spending habits when prices change is referred to by economists as the price elasticity of demand.

Those who trust companies will choose to ratchet down prices on their own, or at least not raise them because the rise in input costs has been slowing, haven’t been listening to what the many companies have told analysts on their post-earnings-report conference calls.

said it will continue to raise prices, even as inflation slows and selling volume declines, as the consumer-products company continues to be laser focused on boosting margins and profits.

And while PepsiCo Inc.

was worried that elasticities would increase, given how its lower-income customers were being particularly pressured by inflation, the beverage and snack giant reported strong results as it witnessed “better elasticities” in most of the markets in which it operated.

“Obviously, there is still carryover pricing, and I don’t think we’ll do anything different than our normal cycles on pricing in the balance of the year,” PepsiCo Chief Financial Officer Hugh Johnston told analysts, according to an AlphaSense transcript.

Basically, as MarketWatch has reported, so-called greedflation is alive and well.

Jamie Cox, managing partner for Harris Financial Group, said as long as the job market stays strong, as it is now, corporate greed will continue to pay off.

“If something is more expensive, and you have a job, you’ll complain about it, but you won’t substitute it for something cheaper,” Cox said. For companies to cut prices, “you have to have the consumer go on strike, and they’re not there yet,” Cox added.

The reason elasticity is so important in the current environment is that, as long as consumers continue to pay the higher prices companies are charging, inflation will remain stubbornly high, making it, in turn, more likely that the Federal Reserve will continue to raise interest rates or, at the very least, not lower them.

But the longer interest rates stay high enough to crimp economic growth, the more likely the stock market will reverse lower as recession fears rise.

“At some point, people are going to say, ‘All right — enough,’ ” said Paul Nolte, senior wealth manager and market strategist at Murphy & Sylvest Wealth Management. “But we just haven’t seen that yet.”

What is elasticity?

Economists use the term “price elasticity of demand” to refer to the way in which consumers adjust their spending habits when prices change.

“Elasticity tries to measure how much more producers will want to produce if prices rise, and how much more consumers will want to buy if prices fall,” explained Bill Adams, chief economist at Comerica.

Elasticity often depends on the type of product a company sells.

For example, consumer-discretionary-goods companies that sell products and services that people want will often experience greater price elasticity than consumer-staples companies that sell things that people need, such as groceries and prescription drugs.

But even for needs, consumers often still have a choice, as less expensive generic, or private-label, alternatives may be available.

PG,

which recently beat earnings expectations as it continued to raise prices, telling analysts that, while there was “some trading into private label,” the overall market share of private-label products was unchanged for the year.

As Harris Financial’s Cox said, consumers may be complaining about higher prices, but they aren’t yet desperate enough to stop buying.

The Federal Reserve’s latest Beige Book economic survey stated that business contacts in some districts had observed a “reluctance” to raise prices as consumers appeared to have grown more sensitive to prices, but other districts reported “solid demand” allowed companies to maintain prices and profitability.

That’s likely why companies and analysts have become less concerned about price elasticity. Based on a FactSet analysis, mentions of the word “elasticity” in press releases and conference calls of S&P 500 companies

increased as inflation and interest rates started surging in early 2022 through the end of the year.

With inflation trends softening this year, the Fed took a brief pause in raising rates in June, helping fuel further stock-market gains, before raising rates again in July.

As the chart shows, “elasticity” popped up in more than 55% of earnings releases and conference calls in mid-2022, but with the second-quarter 2023 earnings-reporting season more than half over, mentions had dropped to about 20%.

Perhaps that will pick up, as retailers, especially those catering to lower-income customers — recall the PepsiCo comment — assess the demand impact of continued price increases.

Meanwhile, the branded-foods company Conagra Brands Inc.
CAG,

whose wide-ranging food brands including Birds Eye, Duncan Hines, Hunt’s, Orville Redenbacher’s and Slim Jim, were starting to see the emergence of a different dynamic.

Chief Executive Sean Connolly said consumers were shifting behavior in some categories as prices remained high. Rather than trade down to lower-priced alternatives, he noticed some consumers buying fewer items overall, “more of a hunkering down than a trading down.”

That’s exactly the kind of consumer behavior that is needed, if companies are to stop feeding into the greedflation phenomenon and to start pulling back on prices.
