A Dispassionate Analysis of the Employment Situation
Wonky piece but worth reading.
Hearing or reading about the state of the beleaguered labor market is impossible to avoid. The financial crisis began more than six years ago, and it has been even longer, since May 2008, from the last bottom in the unemployment rate (4.4%). In this piece, we take stock of the employment situation as it is right now, consider the trend it is following, estimate how long it may take to achieve full employment, and reflect on what may happen when we get there.
Household vs. establishment surveys
If you just look at the headline non-farm payroll changes over the past two months (75k and 113k, a slowdown from 273k published in November), you could conclude that the labor market is slowing once again. Reality is more nuanced, and there is additional trouble in developing conclusions based on data that are highly revised multiple times up to a year after the initial publication (and long after most people actually care). Regardless, those are the data we have now, so let’s analyze the data at face value.
There are in fact two measurements taken by the BLS (US Bureau of Labor Statistics) every month on the size and change in employment: the establishment survey, typically quoted as the “headline number,” which samples about 145,000 businesses per month about their employees, and the household survey, which samples about 60,000 households about their employment. BLS publishes a great guide to its methodology
Figure 1: Last 3 months of Establishment Survey (blue) and Household Survey (red) estimates of m/m payroll change (k)
The household survey (see Figure 1 above, red) has been more emphatic in the job growth picture than the establishment survey (blue). This is actually not abnormal. On a month-to-month basis, the correlation between both surveys is only 47%. The household survey is historically much more (37%) volatile, but over a full year, the two surveys converge with a correlation of 92% (see Figure 2 below).
Figure 2: Scatter-plot of m/m and y/y change in payrolls from establishment and household surveys
Perhaps most importantly, the household survey has led when the economy has been accelerating during an economic turning point in the past four recoveries (see Figure 3 below).
Figure 3: Household (black) and establishment (orange) survey y/y change in payrolls (k) from the past 4 recoveries
The establishment survey leads the household survey down before recessions, but the enormity of evidence against a downturn (leading indicators, fixed investment, asset prices) makes that explanation highly unlikely. It could thus be assumed that the establishment survey may play catch-up to the household survey.
What are households saying?
Although most of the focus on the employment situation is the headline numbers, unemployment rate and change in payrolls, it is composed of thousands of different series, covering employment, unemployment, race, age, gender, educational attainment, sectors/industries, hours, and pay. Change in these series that is not reflected in the headline numbers is often referred to as the internals of the report. They serve to tell us how the composition of the labor market is changing.
Figure 4: Select measures from The Employment Situation from the household survey
The internals are consistent with the household survey, which has averaged 580k payrolls per month over the past three months. Starting with the most common criticism of employment data, the labor force actually grew by 523k, and the long-derided participation rate increased by 0.3%. The unemployment rate dropped across all education levels, but the most significant improvement happened for those holding high school diplomas, where the unemployment rate dropped a staggering –0.6% to 6.5%, an improvement bested only three times in the history of that series.  Perhaps the biggest cause for optimism is the sharp drop in persons employed part-time for economic reasons. This category includes both “slack work or business conditions” as well as “could only find part-time work.” The number of people in this category dropped a staggering 514k. This improvement is in the top 96% of all readings going back to the series start in 1955.  “U6,” the broadest measurement of unemployment and underemployment, dove 0.4% to 12.7%.
The only major internals that did not improve were race related. The white unemployment rate dropped 0.2% to 5.7%, whereas for blacks or African Americans, it edged up the same measure to 12.1%. Asians, who have had the lowest unemployment rate of all races, saw a jump of 0.7% to 4.8%. The long-term trend of unemployment in all these groups is down, so it is likely that this is month-to-month noise that will resolve itself positively. 
All these numbers are subject to large month-to-month variation. What is clear is that the establishment survey payroll number is not consistent with much of the meat of the much broader Employment Situation report. The leading nature of the household survey in expansions provides some indication that the good news it contains will spread to the establishment survey.
Is job growth keeping up with population growth?
Many have noted that actual recovery must exceed population growth to represent real recovery, and once the output gap is closed, true growth must keep up with population growth. This is not precisely true. Although population is slated to grow by somewhere around 22 million over the next decade, which would represent 183k per month, most of this won’t be in the working-age population. Furthermore, the largest age group of workers (Baby Boomers) will be aging out of the labor force. From 2012 to 2024, the BLS estimates that the labor force will grow 10 million, less than half of the population growth. Consequently, it is more appropriate to use labor force growth as the break-even measurement of employment, and it works out to 67k per month. 
Figure 5: BLS projections for population and labor force growth
Although unemployment is above the natural rate, we need more than population growth to close the gap, and we are getting it. Once the gap is closed, however, the rate of job increases will be much smaller than it has been in the past purely on the basis of demographics.
How tight is the labor market?
The natural rate of unemployment is typically defined as its theoretical level if the economy were running at full potential output. That doesn’t mean that there is no unemployment. Too little unemployment would mean inadequate liquidity in the labor markets, which would increase frictions to organizing people in jobs in the optimal manner for output. The sibling to the natural rate is the non-accelerating inflation rate of unemployment (NAIRU), which is the estimate of the lowest unemployment rate that would not be consistent with an accelerated rate of inflation. It seems likely at this juncture that the natural rate is lower than the non-accelerating rate. The consequence of this is that we could achieve higher real growth rates with higher inflation rates.
When we discuss unemployment in the context of labor market tightness, there is both a normative (moral judgment of what should be) as well as a positive (study of what is) aspect. The Federal Reserve has seemingly explicitly adopted the inflation target as a higher priority than the unemployment rate by stating that it will keep rates exceptionally low to support a labor recovery as long as inflation remains below objective: 
The Committee reaffirmed its expectation that the current exceptionally low target range for the federal funds rate of 0 to 1/4 percent will be appropriate at least as long as the unemployment rate remains above 6-1/2 percent, inflation between one and two years ahead is projected to be no more than half a percentage point above the Committee’s 2 percent longer-run goal, and longer-term inflation expectations continue to be well anchored.As a consequence, NAIRU is the most relevant measure of labor market “tightness.” The CBO (US Congressional Budget Office) presently estimates NAIRU to be 5.2%. 
A relevant concept is the Beveridge curve, which plots the relationship between job openings and the unemployment rate.  These two measures generally move in tandem. When the unemployment rate is higher than what the openings rate would be consistent with, it can be assumed that there is structural unemployment; that is, the unemployed do not meet the criteria to get hired by employers. A simple regression equation to calculate what the unemployment rate should be with a given openings rate follows:
UERsupposed = 15.7355 + –3.4623 × openingsUsing the last openings rate (2.8%), this leaves us with an estimated unemployment rate of 6.04% net of structural mismatch, which is 0.6% below the headline level.
Figure 6: Unemployment, and the unemployment rate net of structural mismatches as estimated by the Beveridge Curve
If structural unemployment is higher than estimated, employers will have to start raising wages sooner, and the marginal hire will be marginally less productive, leading to more accelerating inflation as the unemployment rate drops. With the Beveridge curve’s estimate, it’s possible to conclude that NAIRU may make the 80 bp gap between the actual unemployment rate closer than we suspect and that accelerating inflation may materialize in less than a year. At the current pace of 10 bps of improvement in the unemployment rate per month, it would take just eight months to reach the CBO’s 5.2% estimate.
The labor market is most certainly not tight, but it is very possible that — at least positively, even if not normatively — it will be considered tight by the end of this year. Evidence of this can already be observed in wages, whose seasonally unadjusted values are up 2.25% y/y and whose adjusted value grew at a compound annualized pace of more than 3.5%. 
Why does the participation rate or employment-to-population ratio look so bad?
Figure 7: Employment:Population Ratio and Activity Rate for ages 15-64
Most everyone has seen a chart like Figure 7, illustrating the great decline in the participation or employment rate. It is true. But it is not a valid measurement of the labor market or unemployment. Both of these measurements embody the demography, culture, and shift in preferences. Children cannot work, young adults have attained increasingly higher levels of education, young women (predominantly) leave the workforce for rearing children, and the elderly retire.
If you feel compelled to use an employment rate for a labor market indicator, a better measurement is the rate for ages 25–54. We can solve for the equivalent unemployment rate with this simple fitted linear equation:
SupposedUnemploymentRate = 25–54ParticipationRate × –0.4817 + 43.8938which looks like Figure 8 below:
Figure 8: Unemployment rate approximated by 25-54 participation rate (blue) and the actual unemployment rate
This demonstrates that the unemployment rate is largely consistent with the 25–54 participation rate and was in fact recently even higher than the activity rate would have suggested.
The employment situation actually removes the need to guess at the quantity of people not in the labor force voluntarily. We can combine the quantity of unemployed and those not in the labor force who want a job now, shown in Figure 9:
Figure 9: Unemployed + Not in Labor Force, Want Job Now (blue), Unemployment Rate – Natural Rate of Unemployment (red), Unemployment Rate at the Natural Rate (green)
The last time the labor market was considered at full employment (the unemployment rate was at the natural rate), the quantity of those unemployed and those not in the labor force who want a job now were roughly 13 million.
Figure 10: [Unemployed + Involuntarily Not In Labor Force] / [Labor Force + Involuntarily Not In Labor Force] (blue), Unemployment Rate – Natural Rate (red)
Full employment coincides with the “extended unemployment fraction” (Figure 10 above, blue) at 0.08, or 13 million. We henceforth use 13 million (Unemployed + Involuntarily not in labor force) as our estimate for full employment.
Whether that is morally justified is a different discussion, but that rate would be consistent with the definition of full employment that is both historically consistent as well as likely acceptable by most of the political and social classes.
The quantity is 16.59 million now, leaving a shortfall of 3.59 million jobs below full employment. Including a further 67k a month in natural labor force growth, with the rate of the past year’s payroll growth, gives us 2.5 years until full employment. If employment growth is closer to 250k, it falls closer to a year and a half.
The impact of policy
Policy has had a negative impact on employment. The federal government incurred large deficits but did not directly support the labor market. In fact, it contracted payrolls. Had the growth of government payrolls simply grown at its historical rate (Figure 12) and all other things were equal, the employment gap would be just 1.2 million, or we would be just 10 months to full employment.
Figure 12: Government payrolls vs Trend (top), Government Payrolls as % of Employment (bottom)
Lest this lead to the conclusion that this would expand government employment at an outsized rate, this would have put the government payrolls as a percentage of employment almost exactly in line with the 50-year average of 17%.
Fiscal policy isn’t the only thing that holds back employment. Although the Fed now has a zero interest rate policy and is engaging in quantitative easing, it has consistently traded lower inflation for higher unemployment starting with the Volcker chairmanship in 1979.
Figure 13: Employment Gap (Unemployment Rate – NAIRU) pre- and Volcker-on
Before 1980, it was abnormal to run below full employment. After, it has been abnormal to run at or above full employment.
Using the pessimistic assumption of 2.5 years, the United States will have been below full employment for a total of 8.25 years (ending in mid-2016). Presently, this is the third longest duration the country has experienced a labor gap. The longest was the eight years between mid-1979 and early 1988. If the gap closes in the 2.5-year projection, it will narrowly become the longest in post-war history (Figure 11).
Figure 14: Cumulative quarters of unemployment gap
Still, the labor market, including both the unemployed and those not in the work force but wanting jobs now, has approximately half recovered.
The smaller the employment gap gets, the more upward pressure there will be on wages. Higher wages will beget higher inflation. Higher inflation and wages will both facilitate and feed off of an accelerating household formation pace. All of this is consistent with the FOMC (Federal Open Market Committee) consensus for policy tightening starting in 2015  — and probably early in the year — and the eurodollar market projecting a complete normalization of monetary policy in 2019. 
In summary, this will likely be the longest period of time between full employment, narrowly edging out 1979–1988, but the labor market has substantially improved and full employment is solidly in sight.
