In fact, Harvard economist Stefanie Stancheva’s survey work shows that workers tend to think of their eventual catch-up cash pay increases as deserved for their performance, with the product price increases deemed a separate harmful affliction. High, unexpected inflation thus temporarily reduces real earnings, engenders worry and conflict for workers in wage negotiations, and leaves workers feeling like they’ve been shafted of real wage gains even after wages have “caught up.”
Second, given some prices are flexible and others stickier, unexpected inflation delivers arbitrary windfall losses and gains to different groups. Those on fixed pay rates, cash incomes, lenders, and businesses whose costs rise before they can raise prices tend to lose out from the “inflation tax”; workers with market power, fixed interest borrowers, and firms with long input contracts tend to benefit. Members of the public look around and see their relative positions changed by this wealth redistribution. It’s easy for losers to resent those seemingly “profiting” as they suffer – inflation feels inequitable and unpredictable. This is a key cause of demands for redress from the government — to “compensate me, to regulate him, to control x’s prices, and to tax y’s “excess profits”, etc” as the quotation from Axel Leijonhufvud at the start made clear.
Third, inflation creates inefficiency, because it incentivizes people to engage in time-consuming and costly behaviors to try to insulate themselves from its effects. Workers may engage in more conflict to protect their real pay—negotiating more frequently, joining unions, or even striking. Trump had half a point when he said the short-lived longshoremen’s strike was a reaction to inflation.
But it’s not just workers. High inflation means families must reassess their financial plans and rethink consumption patterns. Businesses must go through the costly internal decision-making processes of changing prices more often or even altering products to maintain custom (would customers prefer shrinkflation to a straight price increase, for example?)
Money illusion – the fact many people intuitively think in cash terms rather than “real” terms – means that, in making these adjustments to inflation, consumers and businesses make mistakes in their decisions. All this is occurring in a world in which relative prices between products are constantly changing with supply and demand shifts, meaning it’s not always obvious what’s “inflation” as opposed to a normal price movement for a product or input. High inflation thus makes economic decision making more difficult and, in general, more stressful.
And, finally, even when people recognize that we are living through a high inflation period, there’s mistakes made in forward-looking contracts from guessing how long the inflation will persist and at what level. Though we appear to have been spared this time, one macroeconomic risk is that workers, for example, will come to expect higher future inflation than that which the Federal Reserve delivers, so demanding higher cash pay. This can price workers out of jobs – creating unemployment. It’s why economists got so obsessed about inflation expectations remaining “anchored” when inflation was high.
All told, then, there are good reasons for the public to hate inflation, even though they might not fully understand all its economic consequences, let alone causes. Not only do the public find sharp price increases jarring, but they dislike their wages struggling to keep up, the arbitrary redistribution and conflict inflation brings, and the fact that inflation unmoors their whole sense of what reasonable prices and wages are.
Politicians, of course, know this. It is thus in their interest to deflect blame for inflation away from macroeconomic policymakers in Washington DC and towards other malevolent actors, whether Vladimir Putin for invading Ukraine, or else supposedly greedy corporations. And they have been helped in this effort by misguided public interventions in recent years from a raft of economists, commentators, and even businesses, who have propagated half-truths and misconceptions about the inflation to create an environment where mistaken understandings about its causes are widely held.
Confusing Micro for Macro: How Bad Inflation Analysis Encourages Bad Policy
Inflation, as economists understand it, is a general increase in prices across the economy—reflecting a decline in the value of a dollar unit of currency. This ultimately manifests itself as a proportionate increase in all prices across the economy. It occurs when there is an increase in the growth of money chasing goods relative to the growth of aggregate production, or else a fall in the growth of that output relative to the growth of money spending (a so-called negative supply-shock). The Federal Reserve seeks to keep inflation near target by affecting the money supply and interest rates to influence the money spending side of this see-saw.
Unfortunately, we can’t measure inflation directly, so we rely on price indices like the Consumer Price Index or the Personal Consumption Expenditures price index, which track weighted-average price changes for a “basket” of goods over time. There are well-acknowledged challenges of doing this: the basket of goods must be constantly updated as spending habits change, the quality of goods alter over time, and consumers substitute between products as relative prices fluctuate. At best, then, such indices are very imperfect measures of the macroeconomic inflation we are attempting to calculate.
One key downside of this method of estimating inflation is that it can lead commentators to become obsessed with what’s happening with sub-components of the index, like electricity prices, or rent, or used car prices. Any rapidly rising price is said to be “driving inflation,” as if its absence from the index would lower the calculated inflation rate. While that makes sense as a matter of basic math given these measures of inflation, it can mislead our understanding of inflation’s broader drivers as a macroeconomic phenomenon.
Consider housing rents. In the long-term, rents will go up by underlying inflation plus the price change of rents relative to other goods and services (i.e. the supply and demand conditions of the industry). It would make little logical sense then to look at large rent price increases and assume they have somehow been “driving” inflation – given they themselves are driven, in part, by inflation. Yet this is precisely how stories about inflation are framed. By leading commentators to think of inflation as an aggregation of what’s going on with individual prices, price indices encourage politicians to think “if only we implemented policies to reduce rent growth, then overall inflation would be lower.”
This is often an error. It applies microeconomic thinking to macroeconomic problems. Most policies to hold down rents would do nothing to change the fundamental macroeconomic balance of money growth or output growth. Hold down rents, and there’s more money left over for consumers to bid up other prices by spending more elsewhere. To a first approximation, overall inflation remains unchanged. Narratives that blame inflation on specific product prices—be it used car prices, or rents, or grocery bills—thus distract us from inflation’s true monetary causes. Obsessing over price index subcomponents is one reason why we hear misguided microeconomic “solutions” that fail to address the root causes of inflation—including targeted price controls.
It’s true that large supply shocks within individual markets—like some of the difficulties reopening after the pandemic and the gas price spike after Putin’s invasion of Ukraine—can and did make inflation worse in some periods over the last three years. Major negative supply-shocks undermine the economy’s ability to produce goods and services, lowering real output growth. Less real output for a given amount of money growth means an increased price level – i.e. temporarily higher inflation.
This was the theory that Federal Reserve chairman Jerome Powell had in mind when he first claimed that high inflation would be “transitory” in Fall 2021. The idea was that the spike in prices was driven by one-off factors – mainly post-pandemic supply chain issues — that would quickly dissipate, perhaps even fully reversing in short order. Inflation would thus rise and fall in a few months; the price level itself might even self-correct as supply chains unsnarled. Given the Federal Reserve couldn’t unclog ports or reallocate workers between sectors, but could only affect money spending—demand, through monetary conditions—tightening monetary policy was thought unnecessary and potentially harmful. The central bank just had to sit and wait.
Of course, inflation didn’t fall quickly. In fact, PCE inflation peaked at 7.2 percent in June 2022 and remains slightly above target today. Putin’s invasion of Ukraine in February 2022 and its impact on gas prices gave policymakers another “supply-shock” to help explain away inflation rising further. Yet while the war did raise the price level in 2022, it (just like pandemic supply chain issues) couldn’t explain the magnitude and persistence of the inflation we were seeing. In fact a huge spending boom powered by a mammoth growth in the money supply beforehand was pushing up prices across many sectors significantly even prior to Russian tanks rolling west.
Over time, with more prices adjusting, this reality became more obvious. Policymakers had been mistaking clogged ports and worker shortages as supply bottlenecks driving inflation, when those supply crunches mainly reflected huge increases in demand pushing capacity utilization to its limits. In short, monetary policymakers in DC mistook a demand driven inflation—too much spending—for supply problems they could do little about.
This is easy to see in retrospect, given now supply shocks have largely reversed. Consider the period from January 2021. The PCE price index today is 8.1 percent above where we might have expected it to have been had inflation remained at target throughout that period. How does this compare to trends in total spending on final goods and services (nominal GDP) and real output? Well, relative to if their 2010–2019 trends had continued, nominal GDP is currently 9 percent above where we’d have expected it to be. That indicates excessive total spending growth – a failure of macroeconomic policy. If inflation were all or mainly “supply-shocks” driving permanently higher prices, we might expect real output to be substantially below its pre-pandemic trend today. It is, slightly. But nowhere near the magnitude of the equivalent uplift in spending we’ve seen. In fact, real output is stronger than the Congressional Budget Office forecast in January 2020 (to take another metric, see below). That hardly suggests that unforeseen “supply shocks” are behind the unexpected permanent price level spike we’ve seen.
