Economics. Explained.  

Unit Labor Costs

August 9, 2017

Unit labor costs might be a term that is not familiar to you.  Unit labor costs represent the increase in compensation adjusted for the gains in productivity.  You might think that if labor costs are rising that would put upward pressure on inflation.    It does not matter so much what wages are doing, but what wages adjusted for the change in productivity is doing.  Think of it this way.  If I pay you 3% more money, on the surface you might think that my costs as a businessman have just gone up by 3%.  That is not quite true.  What if you are 3% more productive?  Then I am getting 3% more output from you, so I really do not care.  I am very happy to pay you 3% more money.  In this case, unit labor costs, or labor costs adjusted for the gain in productivity, are 0%.  To take the example one step farther, if I pay you 3% higher wages but you are no more productive, then unit labor costs are rising by 3% and I am probably going to raise my prices to offset the higher cost of labor.  So, a gain of that magnitude in unit labor costs is quite likely to exert upward pressure on inflation.  So always watch what is happening to unit labor costs and not just wages.

Unit labor costs rose 0.6% in the second quarter after having jumped 5.3%% in the first quarter.  The second quarter increase consists of a 1.5% increase in compensation less a 0.9% increase in productivity.  During the past year unit labor costs have declined 0.2%.  But be careful.  This figure has registered significant changes of plus or minus 5% or so for several quarters.  The trend rate appears to be about 1.5% currently.

Looking ahead into 2017 we expect compensation to increase by 2.8% given the tightness in the labor market.  But we also expect productivity growth to climb by 0.9%.  Hence unit labor costs should increase 1.9% versus a 0.2% decline currently.
