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.
