Labor Market Data

By Paul Gomme and Peter Rupert

The BLS released the Job Openings and Labor Turnover Survey (JOLTS) for May on July 6. The data reveal a pretty mixed view. Job openings fell 496,000 and now stands at 9.8 million vacancies. The number of unemployed workers in May was 6.1 million so that there were 1.6 jobs available for each unemployed worker.

The JOLTS data also contains information on the rate at which workers are hired, laid off, quit and job openings. The rates are determined by dividing by the level of employment. The JOLTS covers about 95% of all nonfarm payroll jobs in the US. While the openings rate declined the hiring rate and the quit rate rose. The layoff rate remains at one of its lowest rates since the inception of the JOLTS in December of 2000. Note that all of the other rates are well above their historic average.

The JOLTS data provides some evidence for those looking for nascent signs of a recession. Quit and hiring rates fell through the March-November 2001 and December 2007-June 2009 recessions, and both series started falling prior to the latter recession. The declining quit and hiring rates since early 2022 fit this pattern. Unfortunately, JOLTS only covers three recessions, so it’s tough to make much of the historic precedents, particularly since the February-April 2020 recession was due to COVID-19. Another potentially confounding factor is that both quits and hires are at historically high rates, and the recent declines may be due to reversion to the mean.

The data on initial and continued claims for unemployment insurance also came out on July 6. Initial claims rose slightly but remain relatively subdued. Continued claims have been trending down over the past few months.

On July 7, the employment situation report for June was released by the BLS and showed a payroll employment increase of 209,000 but downward revisions for April and May totaling 110,000 for the two months. One way to think about these changes is that roughly half of the employment gains reported for June were offset by the downward revisions in the previous two months. The employment change in the private sector was the smallest increase over the past couple of years.

The phrase “little changed” was peppered throughout the press release for the Employment Situation Report. The report highlighted gains in employment in government (60,000), health care (41,000), social assistance (24,000) and construction (23,000). Yet the gains in professional and business services, and leisure and hospitality (both 21,000) were described as “little changed”. It would seem that the difference between a gain warranting notice, and “little changed” is 22,000.

Average hours worked in the non-farm sector inched up 0.1 hours to 34.4. That increase, combined with the increase in private employment led to about a 5% in total hours of work in the private sector. There was little change in average hourly earnings.

One way to combine data from JOLTS and the employment report is through the Beveridge curve which plots the vacancy rate (from JOLTS) against the unemployment rate (the household survey). As seen in the chart below, the data up to and including the Great Recession (2007-09) appears to lie on a stable Beveridge curve. After the Great Recession, the Beveridge curve shifted out. And after the pandemic, the Beveridge curve shifted out yet again, with the most recent data in the north west quadrant. One interpretation of an outward shift in the Beveridge curve is that it reflects lower efficiency in the matching process between jobs and workers. Under this interpretation, at a given level of unemployment, firms need to post more vacancies in order to fill jobs. An alternative interpretation is that the outward shifts in the Beveridge curve are due to lower costs of recruiting workers: firms post more vacancies because doing so is simply much cheaper that in the past. One way to distinguish between these two alternative interpretations is to look at how quickly vacancies are filled: less efficient matching says it should take longer while lower job posting costs implies a shorter period of time. Unfortunately, the speed at which vacancies are filled is no longer available.

According to the BLS household survey, employment increased 273,000, the number of people unemployed fell by 140,000 and the labor force increased by 133,000. The participation rate and employment to population ratio were unchanged. The unemployment rate fell from 3.65% to 3.57%.

PCE Inflation and Revised GDP for Quarter 1

The BEA announced May PCE (Personal Consumption Expenditure) data that reinforces the earlier CPI (Consumer Price Index) report: Inflation continues to creep down. Annualizing the month-over-month change in the PCE, inflation for May was 1.55%, well below the Fed’s 2% target. As we have commented before, these month-to-month changes contain a lot of noise and our preferred measure is the annualized 3 month change. By this measure, inflation for May was 2.45% – somewhat higher than the 2.2% reported earlier for the CPI. The headline year-over-year PCE inflation rate for May was 3.85%. As we have emphasized in previous posts, this year-over-year measure of inflation is slow to respond to changes in trend which means it will take some time for the year-over-year inflation rates to reflect the lower inflation rates that have come in over recent months.

Less rosy is the inflation picture coming from core PCE (that is, excluding food and energy). While the month-over-month rate was down in May – from 4.65% to 3.84% – the year-over-year and 3 month measures fell by roughly 0.1 percentage points. Presumably, the reason to look at core PCE inflation is that it provides a better gauge of underlying trend inflation than non-core PCE measures. But for our money, the 3 month PCE inflation rate does a good job capturing developments in trend inflation.

For June, expected inflation is now running below 2% at all horizons. Collectively, the results for CPI, PCE and expected inflation suggest that the tightening of monetary policy over the past year-and-a-half has brought down both actual and expected inflation. In this context, the Fed’s decision in June to pause its tightening of monetary policy seems like a good one, especially if one takes into account the well-known long and variable lags of the effects of monetary policy on the economy.

Finally, while we at Economic Snapshot usually do not comment on GDP (Gross Domestic Product) revisions, we are making an exception for the data released on Thursday by the BEA. The output revision was a very large 0.7 percentage points, from 1.27% to 2.00%. This upward revision of output can be attributed to upward revisions in consumption and exports, and a downward revision of imports (which has a positive effect on output since imports are subtracted from output). These effects were partially offset by small revisions in investment and government spending.

Personal income increased in all but two states, Indiana (-1.0%) and Massachusetts (-0.9%).

May Prices

By Paul Gomme and Peter Rupert

Consumer Price Index

The BLS announced that the Consumer Price Index for all urban consumers (CPI-U) rose 0.1% in May on a seasonally adjusted basis. This 0.1% rise translates into an annualized 1.5%, well below the Fed’s 2% inflation target (the grey line in the figure below). Over the last 12 months it rose 4.13%. The preferred measure of Econsnapshot is a measure of inflation based on a 3 month interval. We prefer this measure because the year-over-year number moves very slowly while the month to month number is very volatile as seen in the graph below. This 3 month inflation rate grew at an annual rate of 2.2%, just above the Fed’s 2% target.

The bad news from the CPI report is that core CPI inflation — which strips out the more volatile food and energy prices — continues to run at 5% or more, much higher than the Fed’s target. Indeed, energy prices have declined significantly, down almost 12% year over year. When looking at core CPI over the last month it is the shelter component that was the largest contributor to the rise in prices, accounting for about 60% of the overall increase. One reason to look at core CPI inflation is that it may be a better measure of trend inflation than headline CPI. If so, the Fed still has work to do to bring inflation back to target.

Of course, Fed watchers know that the Fed focuses on inflation as measured by the personal consumption expenditure (PCE) price index. Over long periods of time, PCE and CPI inflation generally move together. That said, on average PCE inflation runs below both the CPI and core CPI. The PCE for May won’t be released until June 30. Consequently, the recent CPI inflation rates may provide useful information regarding the direction for PCE inflation.

Producer Price Index

Hard on the heels of the CPI report came that for the Producer Price Index (PPI). Inflation as measured by the PPI has been trending down since early 2022. Indeed, at an annual rate, the monthly and 3 month inflation rates are negative meaning that the price index has recently been falling.

Roughly speaking, the CPI reflects prices paid by the typical urban household while the PPI captures prices received by domestic producers of goods and services. Since the PPI captures prices received by domestic producers while the CPI measures prices paid by consumers, it’s tempting to conjecture that changes in the PPI will eventually be reflected in the CPI. However, there are differences in coverage which mean that this logic does not necessarily hold. For example, since the PPI measures prices received by US producers, it does not include prices of imports; the CPI does. Also, nearly 1/4 of the CPI includes the imputed rent of owner-occupied housing; this imputed rent is not included in the PPI. Finally, only some of the goods and services covered by the PPI represent purchases by consumers; the remainder are goods and services used by other producers, capital investment, exports and government. The Bureau of Economic Activity says that the PPI for Personal Consumption comes closest to the coverage of the CPI. Yet, the chart below shows that inflation as measured by this last measure is much more volatile than the CPI. The chart also shows that there is no obvious tendency for PPI inflation to lead CPI inflation.

Automotive Prices

Since the onset of the pandemic, much has been said and written about supply chain problems, with the automotive sector receiving particular attention, such as this article that makes several blunders and left out some important economics as well. Anyone who has tried to buy a new car knows that there are very long delivery lags, especially for electric vehicles. These issues in the new car market has spilled over into the used car market where prices have also risen. Keep in mind that a one time increase in the price of, say, new cars is not what we typically mean by `inflation’. To be sure, such a one time increase will, for a time, lead to an increase in measured inflation. However, this effect will dissipate with time. The chart below is based on price indices from the CPI. The used car inflation rate was much higher than that of new cars from mid-2020 to mid-2022. Recently, used car prices have been falling, and new car price inflation is moderating. Automotive maintenance and repair price inflation continues to increase.

Finally, turn again to the difference between the PPI and other price indices. From the PPI, prices received by domestic automotive producers grew rapidly through 2021 and 2022, with an inflation rate as high as 30%. While those prices have started to decline, the price level has risen 28.5% since May 2020. Granted, automotive inflation as measured by either the CPI or PCE price index also rose, but not nearly as much as recorded by the PPI, and the recent decline in PPI automotive prices has translated into a slowing of these prices as measured by the CPI and PCE.

The June 13-14 meeting of the Fed revealed a pause in rate hikes. As the graphs above show, there are certainly signs that the Fed’s early moves have worked in their favor. As we remarked above, given the core CPI numbers there still may be more work to do…and the Fed made it clear in the statement that more rate hikes are likely.

May Employment Report

By Paul Gomme and Peter Rupert

The BLS announced that payroll employment climbed 339,000 in May. The private sector added 283,000. The bulk of the gain was in the service sector, adding 257,000. The goods sector increased 26,000 but almost all of it, 25,000, in construction.

Although employment climbed 339,000, average weekly hours fell from 34.4 to 34.3 (a decline of 0.1%), throwing a little cold water on the overall report. As shown in the chart below, average weekly hours have trended down since late 2020. Hourly pay, however, climbed 0.3%, from $34.33 to $34.44, and the year over year increase was 4.30%; unfortunately, that growth is still a bit below the year-over-year CPI inflation rate for April, 4.96% (the May CPI has not yet been released).

The household data showed almost exactly the opposite from the establishment survey with an employment decline of 310,000. The employment to population ratio fell slightly from 60.4 to 60.3, and still falls below the pre-pandemic level of 61.1.

The unemployment rate is based on data from the household survey. As mentioned above, employment fell by 310,000 according to the household survey. Combined with a 440,000 increase in the number of unemployed persons, the unemployment rate rose from 3.39% to 3.65%. The changes in the number of employed and unemployed left the labor force participation rate unchanged at 62.6%.

To be “officially” classified as unemployed, an individual must have “actively” looked for a job and available to begin employment. This definition excludes those who are deemed “marginally attached” to the labor force who would like a job, but have not taken sufficiently active measures to find one. The chart below plots the headline unemployment rate along with a measure that includes marginally attached individuals as well as those employed part time for economic reasons (the “U-6” definition). Whereas the headline unemployment rate is 3.7%, the broader measure of unemployment stands at 6.7%. The gap between the two, 3.0%, is about as low as it has been since 1994 when the U-6 measure of the unemployment rate starts.

Until the early 1980s, female unemployment tended to exceed that of men; since then, the pattern has reversed. Since 2021, the male unemployment rate has exceeded that of women by 0.17 percentage points.

Note: We use the terminology of the BLS so as not to add any confusion, in particular, Sex and Race. Also, the BLS uses the terminology Race and Hispanic or Latino Ethnicity.

Historically, Black and African American unemployment rates have exceeded that of other racial groups. Since 1973 (when the data becomes available), the Black and African American unemployment rate has averaged 6.1 percentage points higher than that of whites. Over time, this gap has narrowed; since 2021, it has averaged 3.1 percentage points. Hispanic and Latino unemployment rates lie between that of Blacks/African Americans and whites. (Note that we have seasonally adjusted the Hispanic and Latino unemployment rates using Python’s ARIMA X11 package with default settings; officially seasonally adjusted series are not available.) Over the available data, the Hispanic/Latino unemployment rate exceeded that of whites by 3.15 percentage points; since 2021, by 1.5 points. The Asian unemployment rate is only available since 2003. On average, their unemployment rate is 0.55 percentage points lower than that of whites; since 2021, the gap is only 0.09 points.

We can further look at unemployment rates by sex and race, albeit for those 20 years of age and older. As mentioned earlier, since the early 1980s, for the population as a whole the male unemployment rate has exceeded that of women. While the same is generally true for Blacks/African Americans and whites, the average unemployment rate for Hispanic/Latino women is 0.95 percentage points higher than that of Hispanic/Latino men. Data for Asians is not broken down by sex.

People enter unemployment through various channels. The largest component is for people who lose their job, that represents about half of all of the unemployed. The next largest category is from those who reenter the labor force after a spell of being absent; these are labeled reentrants. Then there are those that voluntarily leave their jobs and those who are just entering the labor force.

Looking across those unemployed, average weeks of unemployment has been trending up somewhat over time. Between 1950 to 1980 average weeks of unemployment hovered between 10 and 15 weeks. Indeed, average weeks never hit 20 weeks until after 1980. Since that time average weeks have hit 20 or more numerous times and today stands at just over 21. The Great Recession and the pandemic had massive effects on weeks of unemployment.

Overall, the labor market continues its strong performance. While the unemployment rate increased it still remains as low as the economy has seen for decades.

April 2023: CPI and Employment

By Paul Gomme and Peter Rupert

The April employment report was released by the BLS and revealed a 253,000 increase in payrolls. However, there were downward revisions totaling 149,000 (down 78,000 in February and 71,000 in March) that threw a little cold water on the report. There were few sectors that had any decline except for temporary help services that shed 23,300 jobs. The workweek held steady at 34.4 hours so that total hours worked increased by 2.1%.

Measured over the past year, average hourly earnings rose 4.45% in April, up from 4.3%. However, when measured relative to the previous month, earnings growth accelerated from 3.3% to 5.9%. As the figure below shows, month-to-month growth rates for earnings are quite choppy. The 3 month change is somewhat smoother; measured this way, earnings growth rose from 3.4% to 4.3%.

The household survey showed that the labor force participation rate remained at 62.6% despite the labor force falling 43,000. The employment to population ratio was also unchanged at 60.4%. The unemployment rate fell from 3.50% to 3.39%.

Unemployment insurance claims spiked up to 264,000, the highest since October of 2021. Continued claims, however, were little changed.

Between March and April, there was little change in inflation as measured by 12 month percentage change in either the Consumer Price Index (CPI) or core CPI (excluding food and energy). However, the annualized monthly percentage change in the CPI rose from 0.6% to 4.5% while core CPI rose from 4.7% to 5.0%. As we have stressed in earlier posts, these annualized inflation rates are quite volatile while 12 month percentage changes respond sluggishly to changes in trend. The 3 month annualized percentage changes strike us as a good compromise between smoothing and quickly capturing trend changes. On this basis, CPI inflation was down slightly, from 3.8% in March to 3.2% in April; core CPI inflation was essentially unchanged at 5.1%. All of these measures of CPI inflation are currently running well above the Fed’s target of 2%.

Given that CPI inflation is higher than the Fed’s 2% target, it may not be surprising that inflation expectations similarly exceed this 2% target. While the May readings for the 1 year and 2 year expected inflation are unchanged at 2.65% and 2.4%, respectively, the 5 year and 10 year expectations rose marginally.

It seems that monetary policymakers no longer look at what’s happening to money growth. That the Fed changed its definition of monetary aggregates starting in May 2020 makes it difficult to take a long view on money growth. Nonetheless, since May 2021 (given the change in the definition of “money” in May 2020, the earliest date for which year-over-year growth rates can sensibly be computed) growth of the monetary aggregates M1 and M2 has slowed. Indeed, both have been contracting since late 2022. A traditional monetarist like Milton Friedman would likely look at the chart below and predict future deflation. One way to think through all this is via the quantity theory of money: Mv = PY where M is money, v velocity, P the price level, and Y real output. This relationship can be recast as: money growth + velocity growth = inflation + real output growth. If velocity is roughly constant (so that its growth rate is 0), and long run real output growth is constant, the quantity theory of money predicts a tight relationship between money growth and inflation. As Milton Friedman put it, “Inflation is always and everywhere a monetary phenomenon.”

Of course, there have been important developments within the banking system. One such development is that the Fed now pays interest on excess reserves of banks held at the Federal Reserve Banks (“excess” meaning above-and-beyond what is required to satisfy reserve requirements). Plausibly, changes in the gap between this interest rate on reserves and the Federal Funds Rate (the rate banks pay in an overnight market for reserves) might explain the above deceleration of money growth. However, as shown below, the interest rate on reserves and the Fed Funds Rate move in lock step.

2023 Q1 GDP Report

By Paul Gomme and Peter Rupert

The BEA announced that Q1 real GDP increased 1.1% at an annual rate. Many in the press have, obviously, noted the declines over the last two quarters indicates the economy is slowing. Indeed, today’s report “undershot” expectations that were around 2%. However, the underlying components were a bit more mixed and the strength of the economy might be in the eye of the beholder. Real consumption spending increased 3.7%, the largest increase over the last 7 quarters, and disposable personal income rose 8.0%.

The output identity, Y = C + I + G + X – M, tells us the uses of output (the “demand” side). If output growth is down, then one or more of the right-hand side components must be down. From above, consumption growth rose from 1.0% in the fourth quarter to 3.7% in the first quarter. Growth in government spending likewise rose, from 3.8% to 4.7%. However, real investment spending fell 12.5% in the first quarter compared to a 4.5% increase in the fourth quarter. Within real investment, real inventories grew 0.4% (up from -3.7%), non-residential structure investment grew 11.2%, and residential structure investment fell by 4.2% (although this decrease was an improvement over the very negative growth rates for this category late in 2022).

While it has become standard in the U.S. to annualize the quarterly growth in GDP, one could also look at the year-over-year growth rate. Now, Q1 does not look so bad relative to the past few quarters and, in fact, has actually increased over the previous quarter.

The Personal Consumption Expenditure Price Index (PCE) rose 4.2% in the first quarter compared to growing 3.7% in the previous quarter, obviously high above the FOMC’s 2.0% target.

These developments lead to a murkier monetary policy outlook. Output growth has slowed, perhaps reflecting the cumulative effects of monetary policy tightening over the past year. Yet, PCE inflation is still well above the Fed’s 2% target (see also the CPI and PPI), and consumption growth actually accelerated in the first quarter. In previous posts, we have noted that the labor market is still quite strong, with an historically low unemployment rate, and roughly two job openings for every unemployed person. Given that, there is nothing new to dissuade the FOMC from another rate hike or two.

March CPI, PPI and inflation expectations

By Paul Gomme and Peter Rupert

The March CPI (Consumer Price Index) brought decidedly mixed news. Year-over-year, CPI inflation fell from 6% in February to 5% in March. Indeed, the year-over-year inflation rate has trended down since mid-2022. However, as we have pointed out in earlier posts, year-over-year measures of inflation are slow to reflect recent changes in trend since they are 12 month averages of past monthly inflation rates. The good news is that monthly (annualized) inflation is down from 4.5% (February) to 0.6% (March), well below the Fed’s 2% inflation target. A glance at the chart below will remind regular readers that monthly inflation rates exhibit considerable variability. Our preferred measure is the 3-month average of monthly inflation rates. This measure declined more modestly, from 4.1% to 3.8%. More importantly, the 3-month average inflation rate is still well above the Fed’s 2% target.

The news is decidedly worse when looking at core CPI inflation (that is, excluding the volatile food and energy components). On a year-over-year basis, core CPI inflation rose from 5.5% in February to 5.6% in March. On the other hand, the monthly core CPI inflation rate fell from 5.6% to 4.7%. Again, we prefer to look at the 3 month average to gauge the direction of trend inflation. The 3 month average of core CPI inflation fell slightly, from 5.2% to 5.1%. More troubling is that these measures are all well above the Fed’s 2% inflation target.

The producer price index (PPI) was released today that offered up a little more good news. The PPI fell 0.5% in March. Moreover, as noted by the BLS, “two-thirds of the decline in the index for final demand can be attributed to a 1.0-percent decrease in prices for final demand goods. The index for final demand services moved down 0.3 percent.”

Finally, short term inflation expectations have risen: For the one year horizon, from 2.1% in March to 2.6% in April; at the two year horizon, from 2.2% to 2.4%. These developments are, presumably, unwelcome by policymakers who are worried about higher inflation expectations becoming entrenched. Fortunately, the five year expected inflation rate fell from 2.2% to 2.1% while 10 year expectations dropped from 2.3% to 2.1%.

Overall, as mentioned at the outset, the news is mixed. Yes, the CPI is down. But, the year over year core CPI is up. The main reason for the difference between the CPI and CORE CPI is that energy prices fell: gasoline, down 17.4%, and fuel oil, down 14.2%. Given the highly volatile nature of food and energy it is useful to pay attention to the core measure.

March Employment Report

By Paul Gomme and Peter Rupert

According to the Establishment Survey from the Bureau of Labor Statistics , employment increased by 236 thousand in March 2023. While this increase is the smallest thus far for 2023, it’s close to the average for the second half of 2022. The BLS also revised the change in employment for February up from 311 thousand to 326 thousand, and revised its reading for January down from 504 thousand to 472 thousand.

The BLS also reported that even though employment was up, average weekly hours were down, so that total hours worked fell 6.8 million hours in March which follows on the heels of a 4.1 million hour decline in February. The chart below shows considerable variation in the change in hours worked.

Private sector employment was up 189,000 and the government sector added 47,000 jobs. The private service sector added 196,000 jobs while the goods producing sector shed 7,000 workers. The largest gain in the service sector came from Leisure and Hospitality, adding 72,000 jobs.

Commentators have noted the decline in average hourly earnings, down 4.24% compared to March of 2022. This has been portrayed as a positive development for policymakers. The reason for this positive portrayal is that if higher inflation expectations become entrenched, then workers will want higher wages (to compensate for the higher inflation) which may lead to wage-price spiral in which wage increases feed to price increases which, in turn, feed into further wage increases, and so on. However, as with our commentary on inflation, year-over-year wage changes (the ones discussed by commentators) are slow to pick up changes in trend. And, as with annualized monthly inflation rates, month-to-month changes in average hourly earnings can be quite noisy; indeed, the annualized percentage change over the month actually rose 3.3% compared to 2.5% for the previous month. A 3 month average of monthly earnings growth smooths out some of the monthly fluctuations while, at the same time, picking up changes in trend in a timely fashion.

Readers of this blog know that inflation has generally been running higher than earnings growth. In previous posts, we have plotted average hourly earnings along side various price levels. Here, instead, we present real average hourly earnings: earnings divided by measures of the general price level. So that these measures are all comparable, we divide the consumer price index (CPI) by its average for 2012. The choice of 2012 is motivated by the fact the personal consumption expenditures (PCE) price index is already set to equal 100 in 2012. The chart below expresses average hourly earnings in 2012 dollars. Both CPI measures exhibit declines since 2021: For the overall CPI, average hourly earnings have declined by roughly $1 per hour, while core CPI records a decline of $0.42 per hour. Alternatively, using the PCE price index, earnings fell by $0.36 per hour; using the Fed’s favorite price index, core PCE, earnings have been essentially flat since the start of 2021.

The Household Survey from the BLS showed a 577,000 increase in employment. Moreover, the labor force, the participation rate and the employment to population ratio all increased. The unemployment rate fell from 3.57% to 3.50%. The Jobs Opening and Labor Turnover Survey still shows significant job openings even though they have come down some over the last few months.

Overall, the employment report shows a still-strong labor market, albeit there are signs of slowing in some areas. The Fed seems to have calmed inflation at this point and, depending on what unfolds over the next month or two, there may be a pause in raising rates since monetary policy tends to work with a lag.

Q4 GDP and PCE Inflation

By Paul Gomme and Peter Rupert

The BEA announced a downward revision from 2.7% to 2.6% in the third and final estimate of Q4 GDP. The revision primarily reflected downward revisions to exports and consumer spending. The final estimate for 2022Q4 GDP did not change the overall stance of the US economy.

Several sources picked up on the fact that the PCE price index, the primary inflation index cited by the Fed, fell. CNBC reported: “On a 12-month basis, core PCE increased 4.6%, a slight deceleration from the level in January.” The New York Times remarked,

The measure of inflation most closely watched by the Federal Reserve slowed substantially in February, an encouraging sign for policymakers as they consider whether to raise interest rates further to slow the economy and bring price increases under control.

The Personal Consumption Expenditures Index cooled to 5 percent on an annual basis in February, down from 5.3 percent in January and slightly lower than economists in a Bloomberg survey had forecast. It was the lowest reading for the measure since September 2021.

NYT, March 31, 2023

However, as we remarked in an earlier post, measured inflation is sensitive to the time horizon over which it is computed. Annualized month-to-month inflation rates are quite volatile; year-over-year inflation is much smoother, but is slow to reflect changes in trend inflation. And it’s trend inflation that policymakers, among others, are concerned about. Yet, identifying trend inflation is difficult. One approach is to average monthly inflation rates over a few months. In the figure below, we include the 3-month average of monthly inflation rates which is our attempt to balance the desire to smooth monthly inflation rates while capturing changes in trend in a timely fashion.

The Fed tends to focus on so-called core PCE inflation for which the volatile food and energy components are removed. Presumably, the reason for looking at core PCE inflation is that it gives a better read on trend inflation. To be sure, core PCE inflation is less volatile, as shown in the chart below. Nonetheless, this measure continues to exhibit large fluctuations when measured on a monthly basis. And, it should not be surprising that the annual (year-over-year) inflation rate is smoother, but slow to reflect changes in trend inflation. Again, we include the 3-month average of monthly inflation rates.

One way to think about the problem of extracting a measure of trend inflation from the data is that observed inflation is composed of trend inflation and an ‘error’ which reflects issues in measuring trend inflation. In the jargon of the profession, we face a signal extraction problem: we are trying to extract the signal (trend inflation) from noisy data (measured inflation). Averaging monthly inflation rates over some horizon (for example, over 3 months, as above) can be thought of as canceling out the positive and negative error terms in this signal extraction problem. (Again, using some jargon, ideally the errors are uncorrelated over time, or independently and identically distributed.)

Finally, what are the policy implications of the latest PCE price index numbers? As mentioned above, some commentators have noted that PCE inflation was down in February relative to January. True enough when looking at either the monthly inflation rate, or the year-over-year inflation rate. However, the 3 month average inflation rate is up. It is hard to make a strong case that there has been a change in trend inflation. In any event, all of the gauges of inflation presented above continue to run well above the Fed’s stated 2% target.

Inflation

The specter of inflation has received considerable attention over the past year. Indeed, the Fed’s increases in its target for the Federal funds rate have been couched in terms of reducing inflation. The Fed’s aggressive increases are likely geared to avoiding an increase in inflation expectations. When will the Fed know it has done enough?

Headline CPI (Consumer Price Index) inflation, based on year-over-year changes in the CPI, has remained well above the Fed’s stated 2% inflation target since early 2021. However, as shown in the chart below, annualized monthly inflation rates were running above target starting in late 2020. This figure illustrates some of the problems associated with looking at annual inflation rates: they are slow at picking up changes in trend. That said, monthly inflation rates are quite volatile as can be seen in mid-2022. In a sense, what we would like is to draw a line free-hand through the monthly inflation rates. The chart below shows that annualized inflation rates over a 3 or 4 month horizon do pretty well in responding reasonably quickly to the ups and downs of the monthly inflation series, while at the same time exhibiting less volatility relative to the monthly series. The 6 month annualized inflation rate suffers the same problem as the year-over-year measure: too much of a lag in following the monthly inflation rate up and down.

So, while monthly inflation rates were pretty much on target by late 2022 (the grey line is at 2%), the 3-month inflation rate was still running above target. In the first two months of 2023, monthly inflation has, again, risen above target; the 3-month average “sees through” these fluctuations. The graph below removes the 4 and 6 month lines to make it a little clearer.

In broad terms, core CPI (that is, excluding food and energy prices) inflation tells the same story: the annual inflation rate took a considerable period of time to reflect the increase in the monthly inflation rate. Roughly speaking, the trend for monthly core CPI inflation has been flat at 5.6% since the start of 2021. Again, the 3-month average core CPI inflation rate presents a nice compromise between smoothing out the month-to-month changes in inflation, and the over-smoothing associated with the annual inflation rate.

The usual motive for looking at core inflation is that removing the volatile food and energy components gives a better measure of trend inflation. Comparing the two charts above, it is difficult to see that core CPI inflation is, in fact, a good measure of the trend in overall CPI inflation.

Those attuned to monetary policy know that the Fed’s preferred measure of inflation is based on the Personal Consumption Expenditure (PCE) price index. Keep in mind that the PCE is only available until January 2023; the February numbers will be available much later this month. The chart below shows that this measure of inflation poked above the Fed’s 2% target early in 2021, and has pretty much stayed there. Once again, the annual inflation rate lagged behind the monthly inflation rate trend; the 3-month inflation rate smooths out many of the wiggles in the monthly inflation rate while responding reasonably quickly to changes in trend.

So, why is this such a big issue? There are some obvious and maybe not so obvious reasons. The most obvious reason for the fight against inflation concerns the purchasing power of a dollar. Inflation erodes nominal earnings. The easiest way to see this is to compare year-over-year changes in the CPI to year-over-year changes in nominal average hourly earnings. In the graph below, the red line plots CPI year-over-year inflation and the blue line plots year-over-year changes in average hourly earnings. When the red CPI line is higher than the blue average hourly earnings line, it means real earnings are falling…an hour of work buys fewer goods and services since prices grew faster than wages. Real wages rise when the blue average hourly earnings line is above the red CPI line. Starting in 2010 until the pandemic, average hourly earnings were growing between 2 and 3%; however, inflation was lower than that and so real earning were rising. After the pandemic, average hourly earnings were growing in the 5-6% range, the fastest growth in a decade, yet real earnings started to fall due to the higher level of inflation. At the height of inflation in mid 2022 (around 9% inflation) real earnings were falling by about 4% since the growth in wages was about 5.4%.

The chart above shows that sometimes workers “win” (earnings growth exceeds inflation), and sometimes they “lose” (earnings growth does not keep up with inflation). What’s relevant is whether workers tend to win more than they lose. To see this, the chart below plots average hourly earnings against two price levels, the CPI and the PCE deflator. All three series are set to 100 at the onset of the pandemic, and are measured in logarithms. There are two practical consequences of using logarithms: (1) straight lines represent constant growth rates, and (2) a constant gap between any two lines represents a constant percent difference between the two. This chart shows that real earnings rose during and after the pandemic: the blue earnings line rose above both of the price indices. No doubt, some of the rise in average hourly earnings early in the pandemic reflected the fact that job losses were concentrated among lower wage workers. Starting in mid-2021, CPI inflation started rising, and the red CPI line exhibits faster growth than the blue earnings line. By mid-2022, the red CPI line passed above the blue earnings line. Since then, average earnings have more-or-less tracked the CPI. By this metric, real earnings are more-or-less back to where they were prior to the pandemic. Notice that when earnings are measured against the PCE price deflator, real earnings are higher now than at the start of the pandemic: the blue earnings line is above the green PCE deflator line.

The next chart gives a longer view of earnings and prices. Now, earnings and prices are set to 100 in early 2006. During the Great Recession, real earnings fell: the red CPI line rose above the blue earnings line. Since then, the blue earnings line consistently exceeds either of the price lines reflecting an increase in real earnings since 2006. However, remember that the gap between earnings and, say, the CPI represents the percentage difference between earnings and prices. With this in mind, after 2010, the gap between earnings and the CPI shrank: real earnings fell relative to 2010. Starting in 2014, a growing gap emerged between earnings and the CPI reflecting increases in real earnings. So, while the chart above indicates that real earnings are back to where they were 3 years ago, over the past 15 years, real earnings have risen.

Inflation, however, does not affect everyone equally. For example, lower income individuals have by way of net wealth. Hand-to-mouth consumers suffer when the prices of the goods they buy rise at a faster clip than their incomes. Those with higher incomes also, typically, have positive net worth. Not only can they buffer their consumption against fluctuations in their real incomes, they also have access to investment opportunities that tend to protect their wealth, and so investment income, from the ravages of inflation. These investment opportunities range from interest-bearing bank accounts to the stock market.

The outcome of the March 21-22 FOMC meeting was a 25 basis point increase in the Fed Funds rate:

Recent indicators point to modest growth in spending and production. Job gains have
picked up in recent months and are running at a robust pace; the unemployment rate has
remained low. Inflation remains elevated.
The U.S. banking system is sound and resilient. Recent developments are likely to result
in tighter credit conditions for households and businesses and to weigh on economic activity,
hiring, and inflation. The extent of these effects is uncertain. The Committee remains highly
attentive to inflation risks.
The Committee seeks to achieve maximum employment and inflation at the rate of
2 percent over the longer run. In support of these goals, the Committee decided to raise the
target range for the federal funds rate to 4-3/4 to 5 percent.
