Again, nice post. I've been using labor share/capacity utilization to get an idea of what the long-term unemployment rate is. My figures align with your own (7 - 7.5%) but there are periods of biased residuals from my model when fit globally. I get the sense that there's another variable that could help explain these deviations and fit into your framework nicely. I'm leaning towards some investment cycle dynamic, but that isn't backed up by anything solid.

I'll reflect on it and let you know if I stumble on anything. If you have any ideas I'm all ears.

Take care.


Can you describe when those biased residuals are seen?

Yes, absolutely. The two periods I see are about Q1 1991 to Q3 1993 and Q4 1997 to Q1 2002. I would consider it an anomaly but given that the dot-com bubble occurred in that time span I think there's something there.


Does this recent post spark any ideas?

It does. However, I think I might have isolated part of the problem. My statements cover Q4 1997 to Q1 2000. Net domestic investment as a percent of GDP increased during this period while capacity utilization fell and labor share stayed relatively constant. Net domestic investment is inversely correlated with the unemployment rate. So given this information it makes sense why the unemployment rate overshot to the downside somewhat. And curiously you inferred that the effective demand limit became inflated during that period of time.

Take it easy. Always enjoy your work.


I think you hit the nail on the head...
Exactly right, the cap util fell but investment shot way up. So the potential of the economy grew faster than real GDP. The result was a mildly higher labor share, and a bubble. That affected the unemployment rate and produced a bias.

Data as of 3rdQ-2018
Effective Demand = $18.433 trillion
Real GDP = $18.671 trillion
Productive Capacity = $24.872 trillion
UT index is at effective demand limit = -0.92%
Effective demand limit = 74.1%
TFUR = 75.1%
ED Fed rate rule = 4.0%
Estimated Natural Real Interest rate = 2.3%
Short-term real interest rate = 2.8%

There is no recession for 3rdQ-2018. Chance of recession is growing as economy has now reached 2nd effective demand limit in this business cycle. I am forecasting that economic conditions will begin to contract in the second half of 2018.
