It's Wednesday, and today I discuss the latest US inflation data, which shows a significant…
Last Friday (December 4, 2015), the US Bureau of Labor Statistics (BLS) released the latest – Employment Situation Summary – November 2015 – which showed that “Total nonfarm payroll employment increased by 211,000 in November, and the unemployment rate was unchanged at 5.0 percent”. According to the press reports the data was above expectations and will probably help the US Federal Reserve Bank decide to increase the policy interest rate when it next meets on December 15 and 16. The revised data for September and October also indicated that the US economy had added (net) employment above what had originally been reported. On average, the US labour market has added 237,000 net jobs per month over the last 12 months. What I was curious about was whether these were predominantly low paid jobs or not. I found that the jobs lost in low-pay sectors in the downturn have more than being offset by jobs added in these sectors in the upturn. However, the massive number of jobs lost in above-average paying sectors have not yet been recovered in the upturn. In other words there is a bias in employment generation towards sectors that on average pay below average weekly earnings.
That question cannot be immediately answered from the summary report provided by the BLS and needs further analysis (and lots of data manipulation). But curiosity got the better of me late today and this is what I came up with. Effectively, since the recovery began in January 2009, there have been 13,712 thousand net jobs added to the US labour market. Of those net employment additions, 28 per cent have been what might be considered low-pay, where that is defined as less than 75 per cent of average weekly earnings.
I was also curious about what happened in the downturn with respect to the jobs lost in net terms and their pay characteristics (at a sectoral level)
Peak US non-farm employment occurred in January 2008 (138,365 thousand) and the trough occurred in December 2009 (129,685 thousand).
Since then, total non-farm employment has grown by 13,215 thousand and total Private employment has grown by 13,712 thousand with government employment falling by 497,000 after growing by 94,000 during the peak-trough period ( January 2008 to December 2009).
Using the top-level North American Industry Classification System (2012 NAICS).
The following table summarises what happened in the peak-trough period.
The first column shows the NAICS sector with the first two rows summarising relevant totals. Total non-farm employment is the sum of total private employment plus Government employment.
The second column shows the total employment in each sector as at December 2009, which was the trough of the downturn following the peak in January 2008.
The third column shows the lost jobs (in thousands) between the Peak and the Trough (these are net losses). So overall 8.8 million jobs were lost in the private sector and they were only partially offset by the 94,000 net jobs added in the government sector.
The next column shows the percentage of those lost jobs per sector, which allows you to see where the downturn impacted mostly. The next column shows average weekly earnings as at December 2009 in US dollars.
The final three columns then distribute the jobs lost according to whether the sector pays 75 per cent or less than average pay, below average pay (the first being a subset of the second), or above average pay as at December 2009.
The totals are below the last three columns and the percent indicates the percent of total jobs lost in each of the pay categories.
So in the downturn, from January 2008 to December 2009, 21 per cent of the jobs lost (net) were in sectors that paid on average below 75 per cent of the overall private sector average pay.
The last two columns divide the total job losses in net terms between above and below average pay and you can see that 85.8 per cent of the total jobs lost in the downturn were in sectors were paying above average pay.
The next table summarises what happened in the period from the trough to the present day (November 2015).
The columns now have a slightly different interpretation, given that we are discussing a growth period rather than a period of contraction.
The second column shows the latest BLS payroll employment data as at November 2015. The next column shows the number of net jobs (in thousands) that have been added by each sector since the trough in December 2009.
The next column is just the percentage of those total jobs added by sector. You can see that with the Government sector in contraction the total jobs added in the Private sector are 103 per cent of the total net jobs added.
The final three columns split these job additions into their pay characteristics Using the sectoral average weekly earnings and the same criteria as in the previous example.
28 per cent of the total jobs added could be considered low-pay, that is, in sectors that play on average weekly wage 75% below the total private sector average weekly earnings.
If we just consider whether the new jobs added are below or above average weekly earnings then the split is almost exactly 50-50.
The data shows that the low-paid jobs that were lost in the downturn have been more than added back (in net terms) in the upturn so far.
However the above average pay jobs that were lost in the downturn have not yet been recovered.
This analysis shows a bias in the recovery towards low-paid in the US, which would have to be considered a disturbing trend given the implications for long-term productivity growth and material prosperity.
Clearly, this analysis is at the aggregated NAICS level and a richer story could be told if we used the two-digit and three-digit typed drill downs into the industry classification.
That sort of analysis is more time-consuming than is feasible for a blog post, where the topic is not one of my primary and current research projects.
That is enough for today!
