26/7/19: Stop Equating Low Unemployment Rate to High Employment Rate

There is always a lot of excitement around the unemployment stats these days. Why, with near-historical lows, and the talk about 'full employment', there is much to be celebrated and traded on in the non-farm payrolls stats and Labor Department press releases. But the problem with all the hoopla around these numbers is that it too often mixes together things that should not be mixed together. Like, say, mangos and frogs, or apples and moths.

Take a look at the following data:

Yes, unemployment is low. Civilian unemployment rate is currently at seasonally-adjusted 3.7% (June 2019), and Unemployment rate for: 20 years and over, at 3.3%, seasonally adjusted. On 3mo average basis, last time we have seen comparable levels of Civilian unemployment was in 1969, and 20+ Unemployment rate was in 2000. Kinda cool, but also revealing: historical lows in unemployment require  Civilian unemployment metric to confirm. Which means that factoring in Government employment, things are bit less impressive today. But let us not split hairs.

Here is the problem, however: record lows in unemployment are not the same as record levels in employment. Low unemployment, in fact, does not mean high employment.

To see this, look at the solid red line, plotting Employment rate for 20 years and older population. The measure currently sits at 71.2 percent and the last three months average is at 71.1 percent.  Neither is historically impressive. In fact, both are below all months (ex-recessions) for 1990-2008. Actually, not shown in the graph, you would have to go back to 1987 to see the same levels of employment rate as today. Oops...

But why is unemployment being low does not equate to employment being high? Well, because of a range of factors, the dominant one being labor force participation. It turns out (as the chart above also shows), we are near historical (for the modern economy's period) lows in terms of people willing to work or search for jobs. Or put differently, we are at historical highs in terms of people being disillusioned with the prospect of searching for a job. Darn! The 'best unemployment stats, ever' and the worst 'willingness to look for a job, ever'.

U.S. Labor Force Participation rate is at 62.9 percent (62.8 percent for the last three months average). And it has been steadily falling from the peak in 1Q 2000 (at 67.3 percent).

When we estimate the relationship between the Employment rate and the two potential factors: the Unemployment rate and the Participation rate, historically (since 1970s) and within the modern economy period (since 1990) as well as in more current times (since 2000), and since the end of the Great Recession (since 2010) several things stand out:

1. Unemployment rate is weakly negatively correlated with Employment rate, or put differently, decreases in unemployment rate are associated with small increases in employment; across all periods;
2. Labor force participation rate is strongly positively correlated with Employment rate. In other words, small increases in labor force participation rate are associated with larger increases in employment; across all periods;
3. Labor force participation rate, in magnitude of its effect on Employment rate, is roughly 14-15 times larger, than the effect of Unemployment rate on Employment rate; across all periods; and
4. The relatively more important impact of Labor force participation rate on Employment, compared to the impact of Unemployment rate on Employment has actually increased (albeit not statistically significantly) in the last 9 years.

These points combined mean that one should really start paying more attention to actual jobs additions and employment rate, as well as participation rate, than to the unemployment rate; and this suggestion is more salient for today's economy than it ever was in any other period on record.

But above all, please, stop arguing that low unemployment rate means high employment. Bats are not cactuses, mangos are not moths and CNN & Fox kommentariate are not really analysts.

26/11/2014: QNHS Q3 2014: Participation and Unemployment Rates

Key summary of the two previous posts is:

1. Unemployment is falling across all durations and all demographic (age-defined) cohorts, but the pressure of long-term unemployment is rising in the cohort of older workers (40 years of age and older), and
2. Irish economy added 27,600 jobs in a year though Q3 2014 compared to Q3 2013. but only 17,300 of these jobs were private sector non-agricultural jobs. On longer-term trend: Non-agricultural Private Sector employment in Q3 2014 was 13.83 lower than 2008 average and Agricultural employment was 4.9% lower. In contrast, Public and State-controlled Sectors employment in Q3 2014 was 3.56% higher than 2008 average. 

Now, lets take a look at the Labour Force Participation Rate. CSO defines this as "The labour force participation rate is computed as an expression of the number of persons in the labour force as a percentage of the working age population. The labour force is the sum of the number of persons employed and of persons unemployed."

In other words, any serious improvement in employment conditions should have one of the two effects:
1) Unemployed moving into employment have zero effect on participation; and
2) New jobs added for new workers (including those previously in unemployment who have left labour force or have moved into training and are now gaining jobs or re-entering workforce) should increase participation.

What do we have in Q3 2014? Judging by the above stats on total employment and unemployment numbers, we should see an improvement in participation rates.

Based on CSO data, Q3 2014 participation rate stood at 60.4, down 0.3 points on Q3 2013. This marks an improvement on 0.5 points drop recorded in Q2 2013. Meanwhile, Unemployment rate dropped to 11.3% in Q3 2014 - a decline of 1.7 points on Q3 2013. The rate of unemployment decline slowed down in Q3 2014 compared to Q2 2014 when the rate dropped 2.1 points.

The above suggests that a significant share of the changes in unemployment is not related to jobs creation (something I will cover in a separate post).

For quarterly changes, consider seasonally-adjusted data. Seasonally-adjusted participation rate stood at 60.0 in Q3 2014, up marginally from 59.9 in Q2 2014 and marginally below 60.1 in Q1 2014. The historical average for the series is 60.7, which means we are still well below the average participation rate. Seasonally-adjusted unemployment rate posted 0.4 points drop to 11.1% in Q3 2014 compared to Q2 2014. Q2 2014 quarterly decline was 0.5 points, which suggests a slowdown in the rate of unemployment improvements in Q3 2014.

Rate of changes unemployment are shown in the chart below.

The key conclusion from the above data is that Ireland's participation rate remains below historical average and despite a slight improvement in Q3 2014 compared to Q2 2014, labour force participation rate remains lower than for the same period in 2013.

8/6/2012: QNHS Q1 2012: Irish broader unemployment metrics

In previous blog posts I covered core results from QNHS, sectoral decomposition of QNHS, and public sector numbers. This post will focus on broader measures of unemployment.

CSO reports seasonally unadjusted data for part time employment that disaggregates part-time employees into those considered to be underemployed and employed. Those considered to be underemployed are individuals who hold part time employment, but are willing and available to work additional hours (new definition).

At the end of Q1 2012 there were 282,600 individuals who were working part time but did not report themselves to be underemployed - a number below 283,300 in Q4 2011 and well below 304,800 in Q1 2011. At the same time, 135,200 individuals were reported as underemployed - down from 141,500 in Q4 2011 and up on 121,900 in Q1 2011. In fact, Q1 2012 marked absolute record for any Q1 since the series started. Keeping in mind that it is seasonally unadjusted series, y/y comparatives are what matters. In Q1 2012, annual rate of increase in underemployed was 10.9% down from 18% in Q1 2011 and up on 5.2% in Q1 2010. Since the crisis began, the number of those underemployed rose 3,458% - that's right - almost 35-fold.

The chart below shows only those underemployed as defined under new methodology.

Combining unemployed and under-employed we have:

Which implies that our 'dependency' ratio - the ratio of full-time employees to total adult population of 15 years and older is still rending down, having already reached a new all time low in Q1 2012:

While traditional seasonally unadjusted unemployment rate is now at 14.7%, combined unemployed, underemployed and marginally attached to labour force ratio to the labour force - or what I term a broad unemployment rate is now 21.94%, up on 21.76% in Q4 2011 and 20.77% in Q1 2011.
