The Latest PCE Report and PCE Inflation v. CPI Inflation

Wall Street Journal columnist Justin Lahart notes that when the Bureau of Labor Statistics (BLS) releases its monthly report on the consumer price index (CPI), the report “generates headlines, features in politicians’ speeches and moves markets.” When the Bureau of Economic Analysis (BEA) releases its monthly report “Personal Income and Outlays,” which includes data on the personal consumption expenditures (PCE) price index, there is much less notice in the business press or, often, less effect on financial markets. (You can see the difference in press coverage by comparing the front page of today’s online edition of the Wall Street Journal after the BEA released the latest PCE data with the paper’s front page on February 13 when the BLS released the latest CPI data.)

This difference in the weight given to the two inflation reports seems curious because the Federal Reserve uses the PCE, not the CPI, to determine whether it is achieving its 2 percent annual inflation target. When a new monthly measure of inflation is released much of the discussion in the media is about the effect the new data will have on the Federal Open Market Committee’s (FOMC) decision on whether to change its target for the federal funds rate. You might think the result would be greater media coverage of the PCE than the CPI. (The PCE includes the prices of all the goods and services included in the consumption component of GDP. Because the PCE includes the prices of more goods and services than does the CPI, it’s a broader measure of inflation, which is the key reason that the Fed prefers it.)

That CPI inflation data receive more media discussion than PCE inflation data is likely due to three factors:

  1. The CPI is more familiar to most people than the PCE. It is also the measure that politicians and political commentators tend to focus on. The media are more likely to highlight a measure of inflation that the average reader easily understands rather than a less familiar measure that would require an explanation. 
  2. The monthly report on the CPI is typically released about two weeks before the monthly report on the PCE. Therefore, if the CPI measure of inflation turns out to be higher or lower than expected, the stock and bond markets will react to this new information on the value of inflation in the previous month. If the PCE measure is roughly consistent with the CPI measure, then the release of new data on the PCE measure contains less new information and, therefore, has a smaller effect on stock and bond prices.
  3. Over longer periods, the two measures of inflation often move fairly closely together as the following figure shows, although CPI inflation tends to be somewhat higher than PCE inflation. The values of both series are the percentage change in the index from the same month in the previous year.

Turning to the PCE data for January released in the BEA’s latest “Personal Income and Outlays” report, the PCE inflation data were broadly consistent with the CPI data: Inflation in January increased somewhat from December. The first of the following figures shows PCE inflation and core PCE inflation—which excludes energy and food prices—for the period since January 2015 with inflation measured as the change in PCE from the same month in the previous year.  The second figure shows PCE inflation and core PCE inflation measured as the inflation rate calculated by compounding the current month’s rate over an entire year. (The first figure shows what is sometimes called 12-month inflation and the second figure shows 1-month inflation.)

The two inflation measures are telling markedly different stories: 12-month inflation shows a continuation in the decline in inflation that began in 2022. Twelve-month PCE inflation fell from 2.6 percent in December to 2.4 percent in January. Twelve-month core PCE inflation fell from 2.9 percent in December to 2.8 percent in December. So, by this measure, inflation continues to approach the Fed’s 2 percent inflation target.

One-month PCE and core PCE inflation both show sharp increases from December to January: From 1.4 percent in December to 4.2 percent for 1-month PCE inflation and from 1.8 percent in December to 5.1 percent in January for 1-month core PCE inflation.

The one-month inflation data are bad news in that they may indicate that inflation accelerated in January and that the Fed is, therefore, further away than it seemed in December from hitting its 2 percent inflation target. But it’s important not to overinterpret a single month’s data. Although 1-month inflation is more volatile than 12-month inflation, the broad trend in 1-month inflation had been downwards from mid-2022 through December 2023. It will take at least a more months of data to assess whether this trend has been broken.

Fed officials didn’t appear to be particularly concerned by the news. For instance, according to an article on bloomberg.com, Federal Reserve Bank of Atlanta President Raphael Bostic noted that: “The last few inflation readings—one came out today—have shown that this is not going to be an inexorable march that gets you immediately to 2%, but that rather there are going to be some bumps along the way.” Investors appear to continue to expect that the Fed will cut its target for the federal funds rate at its meeting on June 11-12.

Surprisingly Strong CPI Report

As we’ve discussed in several blog posts (for instance, here and here), recent macro data have been consistent with the Federal Reserve being close to achieving a soft landing. The Fed’s increases in its target for the federal funds rate have slowed the growth of aggregate demand sufficiently to bring inflation closer to the Fed’s 2 percent target, but haven’t, to this point, slowed the growth of aggregate demand so much that the U.S. economy has been pushed into a recession.

By January 2024, many investors in financial markets and some economists were expecting that at its meeting on March 19-20, the Fed’s Federal Open Market Committee would be cutting its target for the federal funds. However, members of the committee—notably, Chair Jerome Powell—have been cautious about assuming prematurely that inflation had, in fact, been brought under control. In fact, in his press conference on January 31, following the committee’s most recent meeting, Powell made clear that the committee was unlikely to reduce its target for the federal funds rate at its March meeting. Powell noted that “inflation is still too high, ongoing progress in bringing it down is not assured, and the path forward is uncertain.”

Powell’s caution seemed justified when, on February 2, the Bureau of Labor Statistics (BLS) released its most recent “Employment Situation Report” (discussed in this post). The report’s data on growth in employment and growth in wages, as measured by the change in average hourly earnings, might be indicating that aggregate demand is growing too rapidly for inflation to continue to decline.

The BLS’s release today (February 13) of its report on the consumer price index (CPI) (found here) for January provided additional evidence that the Fed may not yet have put inflation on a firm path back to its 2 percent target. The average forecast of economists surveyed before the release of the report was that the increase in the version of the CPI that includes the prices of all goods and services in the market basket—often called headline inflation—would be 2.9 percent. (We discuss how the BLS constructs the CPI in Macroeconomics, Chapter 9, Section 19.4, Economics, Chapter 19, Section 19.4, and Essentials of Economics, Chapter 3, Section 13.4.) As the following figure shows, headline inflation for January was higher than expected at 3.1 percent (measured by the percentage change from the same month in the previous year), while core inflation—which excludes the prices of food and energy—was 3.9 percent. Headline inflation was lower than in December 2023, while core inflation was almost unchanged.

Although the values for January might seem consistent with a gradual decline in inflation, that conclusion may be misleading. Headline inflation in January 2023 had been surprisingly high at 6.4 percent. Hence, the comparision between the value of the CPI in January 2024 with the value in January 2023 may be making the annual CPI inflation rate seem artificially low. If we look at the 1-month inflation rate for headline and core inflation—that is the annual inflation rate calculated by compounding the current month’s rate over an entire year—the values are more concerning, as indicated in the following figure. Headline CPI inflation is 3.7 percent and core CPI inflation is 4.8 percent.

Even more concerning is the path of inflation in the prices of services. Chair Powell has emphasized that as supply chain problems have gradually been resolved, inflation in the prices of goods has been rapidly declining. But inflaion in services hasn’t declined nearly as much. Last summer he stated the point this way:

“Part of the reason for the modest decline of nonhousing services inflation so far is that many of these services were less affected by global supply chain bottlenecks and are generally thought to be less interest sensitive than other sectors such as housing or durable goods. Production of these services is also relatively labor intensive, and the labor market remains tight. Given the size of this sector, some further progress here will be essential to restoring price stability.”

The following figure shows the 1-month inflation rate in services prices. The figure shows that inflation in services has been above 4 percent in every month since July 2023. Inflation in services was a very high 8.7 percent in January. Clearly such large increases in the prices of services aren’t consistent with the Fed meeting its 2 percent inflation target.

How should we interpret the latest CPI report? First, it’s worth bearing in mind that a single month’s report shouldn’t be relied on too heavily. There can be a lot of volatility in the data month-to-month. For instance, inflation in the prices of services jumped from 4.7 percent in December to 8.7 percent in January. It seems unlikely that inflation in the prices of services will continue to be over 8 percent.

Second, housing prices are a large component of service prices and housing prices can be difficult to measure accurately. Notably, the BLS includes in its measure the implicit rental price that someone who owns his or her own home pays. The BLS calculates that implict rental price by asking consumers who own their own homes the following question: “If someone were to rent your home today, how much do you think it would rent for monthly, unfurnished and without utilities?” (The BLS discusses how it measures the price of housing services here.) In practice, it may be difficult for consumers to accurately answer the question if very few houses similar to theirs are currently for rent in their neighborhood.

Third, the Fed uses the personal consumption expenditures (PCE) price index, not the CPI, to gauge whether it is achieving its 2 percent inflation target. The Bureau of Economic Analysis (BEA) includes the prices of more goods and services in the PCE than the BLS includes in the CPI and measures housing services using a different approach than that used by the BLS. Although inflation as measured by changes in the CPI and as measured by changes in the PCE move roughly together over long periods, the two measures can differ significantly over a period of a few months. The difference between the two inflation measures is another reason not to rely too heavily on a single month’s CPI data.

Despite these points, investors on Wall Street clearly interpreted the CPI report as bad news. Investors have been expecting that the Fed will soon cut its target for the federal funds rate, which should lead to declines in other key interest rates. If inflation continues to run well above the Fed’s 2 percent target, it seems likely that the Fed will keep its federal funds target at its current level for longer, thereby slowing the growth of aggregate demand and raising the risk of a recession later this year. Accordingly, the Dow Jones Industrial Average declined by more than 500 points today (February 13) and the interest rate on the 10-year Treasury note rose above 4.3 percent.

The FOMC has more than a month before its next meeting to consider the implications of the latest CPI report and the additional macro data that will be released in the meantime.

A Review of Recent Macro Data

Some interesting macro data were released during the past two weeks. On the key issues, the data indicate that inflation continues to run in the range of 3.0 percent to 3.5 percent, although depending on which series you focus on, you could conclude that inflation has dropped to a bit below 3 percent or that it is still in vicinity of 4 percent.  On balance, output and employment data seem to be indicating that the economy may be cooling in response to the contractionary monetary policy that the Federal Open Market Committee began implementing in March 2022.

We can summarize the key data releases.

Employment, Unemployment, and Wages

On Friday morning, the Bureau of Labor Statistics (BLS) released its Employment Situation report. (The full report can be found here.) Economists and policymakers—notably including the members of the Federal Reserve’s Federal Open Market Committee (FOMC)—typically focus on the change in total nonfarm payroll employment as recorded in the establishment, or payroll, survey. That number gives what is generally considered to be the best indicator of the current state of the labor market.

The previous month’s report included a surprisingly strong net increase of 336,000 jobs during September. Economists surveyed by the Wall Street Journal last week forecast that the net increase in jobs in October would decline to 170,000. The number came in at 150,000, slightly below that estimate. In addition, the BLS revised down the initial estimates of employment growth in August and September by a 101,000 jobs. The figure below shows the net gain in jobs for each  month of 2023.

Although there are substantial fluctuations, employment increases have slowed in the second half of the year. The average increase in employment from January to June was 256,667. From July to October the average increase declined to 212,000. In the household survey, the unemployment rate ticked up from 3.8 percent in September to 3.9 percent in October. The unemployment rate has now increased by 0.5 percentage points from its low of 3.4 percent in April of this year. 

Finally, data in the employment report provides some evidence of a slowing in wage growth. The following figure shows wage inflation as measured by the percentage increase in average hourly earnings (AHE) from the same month in the previous year. The increase in October was 4.1 percent, continuing a generally downward trend since March 2022, although still somewhat above wage inflation during the pre-2020 period.

As the following figure shows, September growth in average hourly earnings measured as a compound annual growth rate was 2.5 percent, which—if sustained—would be consistent with a rate of price inflation in the range of the Fed’s 2 percent target.  (The figure shows only the months since January 2021 to avoid obscuring the values for recent months by including the very large monthly increases and decreases during 2020.)

Job Openings and Labor Turnover Survey (JOLTS) 

On November 1, the BLS released its Job Openings and Labor Turnover Survey (JOLTS) report for September 2023. (The full report can be found here.) The report indicated that the number of unfilled job openings was 9.5 million, well below the peak of 11.8 million job openings in December 2021 but—as shown in the following figure—well above prepandemic levels.

The following figure shows the ratio of the number of job opening to the number of unemployed people. The figure shows that, after peaking at 2.0 job openings per unemployed person in in March 2022, the ratio has decline to 1.5 job opening per unemployed person in September 2022. While high, that ratio was much closer to the ratio of 1.2 that prevailed during the year before the pandemic. In other words, while the labor market still appears to be strong, it has weakened somewhat in recent months.

Employment Cost Index

As we note in this blog post, the employment cost index (ECI), published quarterly by the BLS, measures the cost to employers per employee hour worked and can be a better measure than AHE of the labor costs employers face. The BLS released its most recent report on October 31. (The report can be found here.) The first figure shows the percentage change in ECI from the same quarter in the previous year. The second figure shows the compound annual growth rate of the ECI. Both measures show a general downward trend in the growth of labor costs, although compound annual rate of change shows an uptick in the third quarter of 2023. (We look at wages and salaries rather than total compensation because non-wage and salary compensation can be subject to fluctuations unrelated to underlying trends in labor costs.)

The Federal Open Market Committee’s October 31-November 1 Meeting

As was widely expected from indications in recent statements by committee members, the Federal Open Market Committee voted at its most recent meeting to hold constant its targe range for the federal funds rate at 5.25 percent to 5.50 percent. (The FOMC’s statement can be found here.)

At a press conference following the meeting, Fed Chair Jerome Powell remarks made it seem unlikely that the FOMC would raise its target for the federal funds rate at its December 14-15 meeting—the last meeting of 2023. But Powell also noted that the committee was unlikely to reduce its target for the federal funds rate in the near future (as some economists and financial jounalists had speculated): “The fact is the Committee is not thinking about rate cuts right now at all. We’re not talking about rate cuts, we’re still very focused on the first question, which is: have we achieved a stance of monetary policy that’s sufficiently restrictive to bring inflation down to 2 percent over time, sustainably?” (The transcript of Powell’s press conference can be found here.)

Investors in the bond market reacted to Powell’s press conference by pushing down the interest rate on the 10-year Treasury note, as shown in the following figure. (Note that the figure gives daily values with the gaps representing days on which the bond market was closed) The interest rate on the Treasury note reflects investors expectations of future short-term interest rates (as well as other factors). Investors interpreted Powell’s remarks as indicating that short-term rates may be somewhat lower than they had previously expected.

Real GDP and the Atlanta Fed’s Real GDPNow Estimate for the Fourth Quarter

On October 26, the Bureau of Economic Analysis (BEA) released its advance estimate of real GDP for the third quarter of 2023. (The full report can be found here.) We discussed the report in this recent blog post. Although, as we note in that post, the estimated increase in real GDP of 4.9 percent is quite strong, there are indications that real GDP may be growing significantly more slowly during the current (fourth) quarter.

The Federal Reserve Bank of Atlanta compiles a forecast of real GDP called GDPNow. The GDPNow forecast uses data that are released monthly on 13 components of GDP. This method allows economists at the Atlanta Fed to issue forecasts of real GDP well in advance of the BEA’s estimates. On November 1, the GDPNow forecast was that real GDP in the fourth quarter of 2023 would increase at a slow rate of 1.2 percent. If this preliminary estimate proves to be accurate, the growth rate of the U.S. economy will have sharply declined from the third to the fourth quarter.

Fed Chair Powell has indicated that economic growth will likely need to slow if the inflation rate is to fall back to the target rate of 2 percent. The hope, of course, is that contractionary monetary policy doesn’t cause aggregate demand growth to slow to the point that the economy slips into a recession.

Very Strong GDP Report

This morning the Bureau of Economic Analysis (BEA) released its advance estimate of GDP for the third quarter of 2023. (The report can be found here.) The BEA estimates that real GDP increased by 4.9 percent at an annual rate in the third quarter—July through September. That was more than double the 2.1 percent increase in real GDP in the second quarter, and slightly higher than the 4.7 percent that economists surveyed by the Wall Street Journal last week had expected. The following figure shows the rates of GDP growth each quarter beginning in 2021.

Note that the BEA’s most recent estimates of real GDP during the first two quarters of 2022 still show a decline. The Federal Reserve’s Federal Open Market Committee only switched from a strongly expansionary monetary policy, with a target for the federal funds of effectively zero, to a contractionary monetary policy following its March 16, 2022 meeting. That real GDP was declining even before the Fed had pivoted to a contractionary monetary policy helps explain why, despite strong increases employment during this period, most economists were expecting that the U.S. economy would experience a recession at some point during 2022 or 2023. This expectation was reinforced when inflation soared during the summer of 2022 and it became clear that the FOMC would have to substantially raise its target for the federal funds rate.

Clearly, today’s data on real GDP growth, along with the strong September employment report (which we discuss in this blog post), indicates that the chances of the U.S. economy avoiding a recession in the future have increased and are much better than they seemed at this time last year.

Consumer spending was the largest contributor to third quarter GDP growth. The following figure shows growth rates of real personal consumption expenditures and the subcategories of expenditures on durable goods, nondurable goods, and services. There was strong growth in each component of consumption spending. The 7.6 percent increase in expenditures on durables was particularly strong, particularly given that spending on durables had fallen by 0.3 percent in the second quarter.

Investment spending and its components were a more mixed bag, as shown in the following figure. Overall, gross private domestic investment increased at a very strong rate of 8.4 percent—the highest rate since the fourth quarter of 2021. Residential investment increased 3.9 percent, which was particularly notable following nine consecutive quarters of decline and during a period of soaring mortgage interest rates. But business fixed investment was noticeably weak, falling by 0.1 percent. Spending on structures—such as factories and office buildings—increased by only 1.6 percent, while spending on equipment fell by 3.8 percent.

Today’s real GDP report also contained data on the private consumption expenditure (PCE) price index, which the FOMC uses tp determine whether it is achieving its goal of a 2 percent inflation rate. The following figure shows inflation as measured using the PCE and the core PCE—which excludes food and energy prices—since the beginning of 2015. (Note that these inflation rates are measured using quarterly data and as compound annual rates of change.) Despite the strong growth in real GDP and employment, inflation as measured by PCE increased only from 2.5 percent in the second quarter to 2.9 percent in the third quarter. Core PCE, which may be a better indicator of the likely course of inflation in the future, continued the long decline that began in first quarter of 2022 by failling from 3.7 percent to 2.9 percent.

The combination of strong growth in real GDP and declining inflation indicates that the Fed appears well on its way to a soft landing—achieving  a return to its 2 percent inflation target without pushing the economy into a recession. There are reasons to be cautious, however.

GDP, inflation, and employment data are all subject to—possibly substantial—revisions. So growth may have been significantly slower than today’s advance estimate of real GDP indicates. Even if the estimate of real GDP growth of 4.9 percent proves in the long run to have been accurate, there are reasons to doubt whether output growth can be maintained at near that level. Since 2000, annual growth in real GDP has average only 2.1 percent. For GDP to begin increasing at a rate substantially higher than that would require a significant expansion in the labor force and an increase in productivity. While either or both of those changes may occur, they don’t seem likely as of now.

In addition, the largest contributor to GDP growth in the third quarter was from consumption expenditures. As households continue to draw down the savings they built up as a result of the federal government’s response to the Covid recession of 2020, it seems unlikely that the current pace of consumer spending can be maintained. Finally, the lagged effects of monetary policy—particularly the effects of the interest rate on the 10-year Treasury note having risen to nearly 5 percent (which we discuss in our most recent podcast)—may substantially reduce growth in real GDP and employment in future quarters.

But those points shouldn’t distract from the fact that today’s GDP report was good news for the economy.

Solved Problem: How Do You Calculate GDP?

Supports: Macroeconomics, Chapter 8, Economics, Chapter 18, and Essentials of Economics, Chapter 12.

In a report, a consulting firm claimed that wealth is a better measure of the financial health of an economy than is GDP. They made the following argument:

“GDP counts items multiple times. For instance, if someone is paid USD 100 for a product/service and they then pay someone else that same USD 100 for another product/service, that adds USD 200 to a country’s GDP, despite the fact that only USD 100 was produced at the start.”

Briefly explain whether you agree with the consulting firm’s argument.

Solving the Problem

Step 1:  Review the chapter material. This problem is about how GDP is calculated, so you may want to review Macroeconomics, Chapter 8, Section 8.1, “Gross Domestic Product Measures Total Production” (Economics, Chapter 18, Section 8.1 and Essentials of Economics, Chapter 12, Section 12.1)

Step 2: Answer the question by explaining whether the consulting firm has correctly explained how the Bureau of Economic Analysis calculates GDP. The consulting firm has given an incorrect explanation of how GDP is calculated, so you should disagree with the firm’s argument. The definition of GDP in the chapter is: “The market value of all final goods and services produced in a country during a period of time.” The quoted excerpt is incorrect in claiming that GDP counts items multiple times. In terms of the example, if you pay $100 for a (very nice!) haircut at a hair salon and the owner of the hair salon uses that $100 to buy groceries, both transactions should be included in GDP because they represent $200 worth of production—a $100 haircut and $100 worth of groceries. Only buying and selling of used goods or of intermediate goods is excluded from GDP. In other words, contrary to the firm’s claim, when the Bureau of Economic Analysis calculates GDP, it doesn’t “count items multiple times.”

Should the Fed Be Looking at the Median CPI?

For years, all the products for sale in Dollar Tree stores had a price of $1.00 or less. But as inflation increased, the company had to raise its maxium prices to $1.25. (Thanks to Lena Buonanno for sending us the photo.)

There are multiple ways to measure inflation. Economists and policymakers use different measures of inflation depending on the use they intend to put the measure of inflation to. For example, as we discuss in Macroeconomics, Chapter 9, Section 9.4 (Economics, Chapter 19, Section 19.4), the Bureau of Labor Statistics (BLS) constructs the consumer price index (CPI) as measure of the cost of living of a typical urban household. So the BLS intends the percentage change in the CPI to measure inflation in the cost of living as experienced by the roughly 93 percent of the population that lives in an urban household. (We are referring here to what the BLS labels CPI–U. As we discuss in this blog post, the BLS also compiles a CPI for urban wage earners and clerical workers (or CPI–W).)

As we discuss in an Apply the Concept in Chapter 15, Section 15.5, because the Fed is charged by Congress with ensuring stability in the general price level, the Fed is interested in a broader measure of inflation than the CPI. So its preferred measure of inflation is the personal consumption expenditures (PCE) price index, which the Bureau of Economic Analysis (BEA) issues monthly. The PCE price index is a measure of the price level similar to the GDP deflator, except it includes only the prices of goods and services from the consumption category of GDP. Because the PCE price index includes more goods and services than the CPI, it is suits the Fed’s need for a broader measure of inflation. The Fed uses changes in the PCE to evaluate whether it’s meeting its target of a 2 percent annual inflation rate.

In using either the percentage change in the CPI or the percentage change in the PCE, we are looking at what inflation has been over the previous year. But economists and policymakers are also looking for indications of what inflation may be in the future. Prices of food and energy are particularly volatile, so the BLS issues data on the CPI excluding food and energy prices and the BEA does the same with respect to the PCE. These two measures help avoid the problem that, for example, a period of high gasoline prices might lead the inflation rate to temporarily increase. Note that inflation caclulated by excluding the prices of food and energy is called core inflation.

During the surge in inflation that began in the spring of 2021 and continued into the fall of 2022, some economists noted that supply chain problems and other effects of the pandemic on labor and product markets caused the prices of some goods and services to spike. For example, a shortage of computer chips led to a reduction in the supply of new cars and sharp increases in car prices. As with temporary spikes in prices of energy and food, spikes resulting from supply chain problems and other effects of the pandemic might lead the CPI and PCE—even excluding food and energy prices—to give a misleading measure of the underlying rate of inflation in the economy. 

To correct for this problem, some economists have been more attention to the measure of inflation calculated using the median CPI, which is compiled monthly by economists at the Federal Reserve Bank of Cleveland. The median CPI is calculated by ranking the price changes of every good or service in the index from the largest price change to the smallest price change, and then choosing the price change in the middle. The idea is to eliminate the effect on measured inflation of any short-lived events that cause the prices of some goods and services to be particularly high or particularly low. Economists at the Cleveland Fed have conducted research that shows that, in their words, “the median CPI provides a better signal of the underlying inflation trend than either the all-items CPI or the CPI excluding food and energy. The median CPI is even better at forecasting PCE inflation in the near and longer term than the core PCE price index.”

The following figure shows the three measures of inflation using the CPI for each month since January 2019. The red line shows the unadjusted CPI, the green line shows the CPI excluding food and energy prices, and the blue line shows median CPI. To focus on the inflation rate in a particular month, in this figure we calculate inflation as the percentage change in the index at an annual rate. That is, we calculate the annual inflation rate assuming that the inflation rate in that month continued for a year.

Note that for most of the period since early 2021, during which the inflation rate accelerated, median inflation was well below inflation measured by changes in the unadjusted CPI. That difference reflects some of the distortions in measuring inflation arising from the effects of the pandemic.

But the last two values—for July and August 2022—tell a different story. In those months, inflation measured by changes in the CPI excluding food and energy prices or by changes in median CPI were well above inflation measured by changes in the unadjusted CPI.  In August 2022, the unadjusted CPI shows a low rate of inflation—1.4 percent—whereas the CPI excluding food and energy prices shows an inflation rate of 7.0 percent and the median CPI shows an inflation rate of 9.2 percent. 

We should always be cautious when interpreting any economic data for a period as short as two months. But data for inflation measured by the change in median CPI may be sending a signal that the slowdown in inflation that many economists and policymakers had been predicting would occur in the summer of 2022 isn’t actually occurring. We’ll have to await the release of future data to draw a firmer conclusion.

Is the U.S. Economy in a Recession? Real GDP versus Real GDI

Photo from the Wall Street Journal.

The Bureau of Economic Analysis (BEA) publishes data on gross domestic product (GDP) each quarter. Economists and media reports typically focus on changes in real GDP as the best measure of the overall state of the U.S. economy. But, as we discuss in Macroeconomics, Chapter 8, Section 8.4 (Economics, Chapter 18, Section 18.4), the BEA also publishes quarterly data on gross domestic income (GDI). As we discuss in Chapter 8, Section 8.1 when discussing the circular-flow diagram, the value of every final good and services produced in the economy (GDP) should equal the value of all the income in the economy resulting from that production (GDI). The BEA has designed the two measures to be identical by including in GDI some non-income items, such as sales taxes and depreciation. But as we discuss in the Apply the Concept, “Should We Pay More Attention to Gross Domestic Income?” GDP and GDI are compiled by the BEA from different data sources and can sometimes significantly diverge. 

A large divergence between the two measures occurred in the first half of 2022. During this period real GDP declined—as shown by the blue line in the following figure—after which some stories in the media indicated that the U.S. economy was in a recession.  But real GDI—as shown by the red line in the figure—increased during the same two quarters. So, was the U.S. economy still in the expansion that began in the third quarter of 2020, rather than in a recession?  Or, as an article in the Wall Street Journal put it: “A Different Take on the U.S. Economy: Maybe It Isn’t Really Shrinking.”

In fact, most economists do not follow the popular definition of a recession as being two consecutive quarters of declining real GDP. Instead, as we discuss in Chapter 10, Section 10.3, economists typically follow the definition of a recession used by the National Bureau of Economic Research: “A recession is a significant decline in activity spread across the economy, lasting more than a few months, visible in industrial production, employment, real income, and wholesale-retail trade.” 

During the first half of 2022, most measures of economic activity were expanding, rather than contracting. For example, the first of the following figures shows payroll employment increasing in each month in the first half of 2022. The second figure shows industrial production also increasing during most months in the first half of 2022, apart from a very slight decline from April to May after which it continued to increase. 

Taken together, these data indicate that the U.S. economy was likely not in a recession during the first half of 2022. The BEA revises the data on real GDP and real GDI over time as various government agencies gather more information on the different production and income measures included in the series. Jeremy Nalewaik of the Federal Reserve Board of Governors has analyzed the BEA’s adjustments to its initial estimates of real GDP and real GDI. He has found that when there are significant differences between the two series, the BEA revisions usually result in the GDP values being revised to be closer to the GDI values. Put another way, the initial GDI estimates may be more accurate than the initial GDP estimates.

If that generalization holds true in 2022, then the BEA may eventually revise its estimates of GDP upward, which would show that the U.S. economy was not in a recession in the first of half of 2022 because economic activity was increasing rather than decreasing.
