May’s jobs gains, released this morning, show that only 38,000 new jobs were added this May, down from an average of 178,000 over the first four months of the year, and the least new jobs added since September 2010.

This year’s monthly job gains and losses can indicate how the economy is doing once they are corrected to account for the pattern we already expect in a process called seasonal adjustment. The approach for this seasonal adjustment that is presently used by the Bureau of Labor Statistics (BLS) puts very heavy weight on the current and last two years of data in assessing what are the typical patterns for each month.

In my paper “Unseasonal Seasonals?” I argue that a longer window should be used to estimate seasonal effects. I found that using a different seasonal filter, known as the 3x9 filter, produces better results and more accurate forecasts by emphasizing more years of data. The 3x9 filter spreads weight over the most recent six years in estimating seasonal patterns, which makes them more stable over time than in the current BLS seasonal adjustment method.

I calculate the month-over-month change in total nonfarm payrolls, seasonally adjusted by the 3x9 filter, for the most recent month. The corresponding data as published by the BLS are shown for comparison purposes. According to the alternative seasonal adjustment, the economy actually lost about 4,000 jobs in May (column Wright SA), compared to the official BLS total of 38,000 gained (column BLS Official).

In addition to seasonal effects, abnormal weather can also affect month-to-month fluctuations in job growth. In my paper “Weather-Adjusting Economic Data” I and my coauthor Michael Boldin implement a statistical methodology for adjusting employment data for the effects of deviations in weather from seasonal norms. This is distinct from seasonal adjustment, which only controls for the normal variation in weather across the year. We use several indicators of weather, including temperature and snowfall.

We calculate that weather in May had a negligible effect on employment, bringing up the total by only 4,000 jobs (column Weather Effect). Our weather-adjusted total, therefore, is 34,000 jobs added for May (column Boldin-Wright SWA). This is not surprising, given that weather in May was in line with seasonal norms.

Unfortunately, neither the alternative seasonal adjustment, nor the weather adjustment, makes todays jobs report any more hopeful. They make little difference and, if anything, make the picture more gloomy.

a. Applies a longer window estimate of seasonal effects (see Wright 2013).
b. Includes seasonal and weather adjustments, where seasonal adjustments are estimated using the BLS window specifications (see Boldin & Wright 2015). The incremental weather effect in the last column is the BLS official number less the SWA number.

Federal Reserve chair Janet Yellen just gave a speech in Philadelphia that acknowledges a weak jobs report last Friday. She rightly cautions us not to place too much weight on any single month’s numbers. Overall, her talk seems to have raised confidence in the financial markets about where the economy is heading, based on a wider range of recent indicators besides the numbers reported in the jobs report, for example, on consumer spending and home construction. These suggest areas of continued strength in the economy.

Still, the report last Friday was really lousy, and not really a one-off event (and not just due to the Verizon strike). Since the end of 2015, the job growth numbers have been on a pretty steady downward trend, with growth above 200,000 in only one month (February). A few other indicators in the report were also quite disappointing: the numbers of workers in part-time jobs because they can’t find full-time work bounced back up; and labor force participation dropped considerably. Indeed, about 800,000 workers have left the labor force in the last 2 months, including many who are well below retirement age. Their exit reverses some of the progress in labor force participation we had seen late last year and early this year.

On the other hand, not all numbers in the report were terrible. Wage growth held up reasonably well. Over the past 2 months, wages have risen by over 3 percent (on an annualized basis), suggesting a labor market that is tight enough to finally generate some earnings improvements for workers who already have jobs.

Overall, the different indicators highlight two sets of forces driving the labor market: Demand-side problems, suggesting employers still need too few workers to generate full employment; and supply-side problems, where worker availability and skills are starting to constrain the amount of hiring going on.

Indeed, the latter problems might explain the peculiar combination of weak and strong indicators we see in the report. For instance, if the drop in labor force participation is permanent, then the 4.7 percent unemployment rate accurately suggests that the amount of slack in the labor market is lower than we thought. Employers are likely finding it a bit harder to hire the workers with the skills and experience they really want. Consequently, our long economic expansion is finally translating into higher wage growth for those already employed or about to be.

Another possibility, perhaps, is that productivity growth is finally rebounding a bit, after the dismal numbers we’ve observed in the past few years, where GDP growth has been modest but employment growth has been strong. Indeed, some recovery in productivity is a precondition for real wage growth to last, even in a tighter labor market. In this scenario, output growth would now be more robust than employment growth, reversing some of the striking declines we’ve observed in the productivity numbers.

Of course, what might be most convincing is a combination of the labor demand- and supply-side stories, along the following lines: the labor market is gradually approaching capacity, though it is not there yet. I don’t think it will get there until we are closer to 4 percent unemployment. But employer difficulties finding skilled workers matter more in this type of market than in the earlier years of recovery after the Great Recession. Such pressure raises wages for employed workers and those with appropriate skill levels. On the other hand, workers with weaker skills still face dismal prospects, and their exit from the labor force reflects their bleak prospects. The growth of labor demand might really be shrinking, as productivity rebounds a bit and as weakness in business investment and export demand are felt in the job market.

We won’t know for sure how much of this story is accurate until we get more jobs and productivity reports over the next few months. But, in the meantime, my bet is on just such a mixed reading, which suggests that a very gradual lifting of economic stimulus is appropriate, without, however, moving too quickly in the opposite direction.

November's U.S. Bureau of Labor Statistics (BLS) employment report showed continued improvement in the job market, with employers adding 211,000 workers to their payrolls and hourly pay edging up compared with its level a year ago. The pace of job growth was similar to that over the past year and somewhat slower than the pace in 2014. For the 69^th consecutive month, private-sector payrolls increased. Since the economic recovery began in the third quarter of 2009, all the nation’s employment gains have occurred as a result of expansion in private-sector payrolls. Government employment has shrunk by more than half a million workers, or about 2.5 percent. In the past twelve months, however, public payrolls edged up by 93,000.

The good news on employment gains in November was sweetened by revised estimates of job gains in the previous two months. Revisions added 8,000 to estimated job growth in September and 27,000 to job gains in October. The BLS now estimates that payrolls increased 298,000 in October, a big rebound compared with the more modest gains in August and September, when payrolls grew an average of about 150,000 a month.

Average hourly pay in November was 2.3 percent higher than its level 12 months earlier. This is a slightly faster rate of improvement compared with the gains we saw between 2010 and 2014. A tighter job market may mean that employers are now facing modestly higher pressure to boost employee compensation. The exceptionally low level of consumer price inflation means that the slow rate of nominal wage growth translates into a healthy rate of real wage improvement. The latest BLS numbers show that real weekly and hourly earnings in October were 2.4 percent above their levels one year earlier. Not only have employers added more than 2.6 million workers to their payrolls over the past year, the purchasing power of workers' earnings have been boosted by the slightly faster pace of wage gain and falling prices for oil and other commodities.

The BLS household survey also shows robust job gains last month. Employment rose 244,000 in November, following a jump of 320,000 in October. More than 270,000 adults entered the labor force in November, so the number of unemployed increased slightly, leaving the unemployment rate unchanged at 5.0 percent. In view of the low level of the jobless rate, the median duration of unemployment spells remains surprisingly long, 10.8 weeks. Between 1967 and the onset of the Great Recession, the median duration of unemployment was 10.8 weeks or higher in just seven months. Since the middle of the Great Recession, the median duration of unemployment has been 10.8 weeks or longer for 82 consecutive months. The reason, of course, is that many of the unemployed have been looking for work for a long time. More than one-quarter of the unemployed—slightly more than two million job seekers—have been jobless for at least 6 months.  That number has been dropping for more than five years, but remains high relative to our experience before the Great Recession.

If there is bad news in the latest employment report, it's the sluggish response of labor force participation to a brighter job picture. The participation rate of Americans 16 and older edged up 0.1 point in November but still remains 3.5 percentage points below its level before the Great Recession. About half the decline can be explained by an aging adult population, but a sizeable part of the decline remains unexplained. The participation rate of men and women between 25 and 54 years old is now 80.8 percent, exactly the same level it was a year ago but 2.2 points lower than it was before the Great Recession. Despite the fact that real wages are higher and job finding is now easier than was the case earlier in the recovery, the prime-age labor force participation rate remains stuck well below its level before the recession. How strong must the recovery be before prime-age adults are induced to come back into the work force? Even though the recovery is now 6 and a half years old, we still do not know.
