Much has already been written about the employment report for May
2018 that was published on Friday, June 1. The unemployment rate, like your
friendly mole, once again dug deeper and went to an 18-year low of 3.8%. This
means that the labor market is growing tighter, which means that firms are
finding it harder to find the right employees. There are many articles being
written now about this business challenge as firms use innovative ways to try
to attract new employees or to hold on to existing ones. Of course, a common
approach to attracting and keeping workers is raising wages and benefits.
Wages, therefore, become a
critical economic variable these days. This week I decided to look at wage
behavior in the USA to see if there are signs of firms using wages to ameliorate labor market tightness. The graph at the bottom looks at monthly percentage
changes in average earnings for all employees.
Reading graphs is definitely an
art form. I ain't Picasso but let's give it a shot. Each dot on this graph records how much earnings grew in that month.
If you go to the very last dot on the graph, it says that in May of 2018
earnings grew by 0.298 compared to the value in April of 2018. The one-month percentage
change was 0.298%. For sake of our eyeballs, let's round up and call that a one-month increase of about 0.3% in May. If that one-month increase lasted for a full
year, then wages would increase by about 3.6%.
That's a big if and is only
suggested so that we can put the one-month gain into an annual perspective. If
Lebron scored 12 points in the first quarter of a game, he scored 12 points! But we
could say something like -- dude, that's like scoring 48 points in a whole
game. Wow. Groovy. He may or may not score 48 in that game but the 48 gives us
another way of understanding the 12 he did score in Q1.
Whew. I am thirsty. So if you
read the above, you know that the 0.298 increase in May of 2018 is about a 3.5%
annualized increase. That sounds pretty good. If the cost of living went up by
2% in May, then you might be happy that your wages grew faster than your
expenses.
The reason I placed the whole
graph below is that we can evaluate the most current increase better by looking
at past changes. This graph has monthly ups and downs from April of 2006 to May of
2018, so we can compare over a 13-year period. My task today is to evaluate
the 0.298 of May 2018.
Is it the highest point on the graph?
Absolutely not. Just in the last couple of years there were many months
that had stronger growth in earnings.
Is it the lowest point on the
graph?
Absolutely not. There are even more months in which earnings grew much slower than 0.298.
Absolutely not. There are even more months in which earnings grew much slower than 0.298.
Is there any pattern to the monthly changes?
It looks like whack-a-mole to me. Most ups are followed swiftly by downs and vice versa.
Do you observe an upward or
downward trend in the dots?
From about April 2006 through June 2010, there seems to be a downward trend. That is, on average, wage growth seemed to decline. Wages were growing but at a slower pace.
But from June 2010 to about October 2011, the wage growth picked up. From my eyeball, it appears that the average monthly percentage change during that time was about 0.2 or an annual rate of about 2.4%.

Then from 2012 to now, there
appears to be no discernible trend change in earnings. For six years, we got ups
and downs around a mean that suggests wage change at about 2.4% per year. If
you removed the crazy negative data point in October of 2017, you might see
some increase in trend starting around October of 2016. Of course, you might
also see pink elephants.
