Quote of the Day: Jeremy Grantham -- US on the Road to Zero Growth Long-Term

Summary

• The U.S. GDP growth rate that we have become accustomed to for over a hundred years – in excess of 3% a year – is not just hiding behind temporary setbacks. It is gone forever. Yet most business people (and the Fed) assume that economic growth will recover to its old rates.
• Population growth that peaked in the U.S. at over 1.5% a year in the 1970s will bob along at less than half a percent. This is pretty much baked into the demographic pie. After adjusting for fewer hours worked per person, man-hours worked annually are likely to be growing at only 0.2% a year.
• Productivity in manufacturing has been high and is expected to stay high, but manufacturing is now only 9% of the U.S. economy, down from 24% in 1900 and 15% in 1990. It is on its way to only 5% by 2040 or so. There is a limit as to how much this small segment can add to total productivity.
• Growth in service productivity in contrast is low and declining. Total productivity is calculated to be just 1.3% through 2030, if we use current accounting methods.
• Resource costs have been rising, conservatively, at 7% a year since 2000. If this is maintained in a world growing at under 4% and a developed world at under 1.5% it is easy to see how the squeeze will intensify.
• Going forward, GDP growth (conventionally measured) for the U.S. is likely to be about only 1.4% a year, and adjusted growth about 0.9%. The price rise might even accelerate as cheap resources diminish. If resources increase their costs at 9% a year, the U.S. will reach a point where all of the growth generated by the economy is used up in simply obtaining enough resources to run the system. It would take just 11 years before the economic system would be in reverse! If, on the other hand, our resource productivity increases, or demand slows, cost increases may decelerate to 5% a year, giving us 31 years to get our act together. Of course, with extraordinary, innovative breakthroughs we might do even better, but we certainly shouldn’t count on that. (Bear in mind that we don’t even know precisely why the prices started to rise so sharply in 2000.) Excessive optimism and doing little could be extremely dangerous.
• For a few years fracking will add helpfully to growth: my guess is that the benefit will peak at about 0.5% within five years, but be modest over longer periods. The key concept here for understanding growth is to know when the maximum upward push will occur.
• Increasing climate damage, reflected mainly in food prices and flood damage, is going to increase. With any luck this will not be severe before 2030 (we allow for a 0.1% setback) but it is very likely to accelerate between 2030 and 2050. A great deal will depend on our responses.
• The bottom line for U.S. real growth, according to our forecast, is 0.9% a year through 2030, decreasing to 0.4% from 2030 to 2050 (see table on Page 16). This is all done presuming no unexpected disasters, but also no heroics, just normal “muddling through.”
• Investors should be wary of a Fed whose policy is premised on the idea that 3% growth for the U.S. is normal.
• Remember, it is led by a guy who couldn’t see a 1-in-1200-year housing bubble! Keeping rates down until productivity surges above its last 30-year average or until American fertility rates leap upwards could be a very long wait!

~ Jeremy Grantham, from On the Road to Zero Growth


Grouch: I'm not as pessimistic in the long-run as Grantham, but I am pessimistic about US growth for the next 4 - 6 years. Much damage will be inflicted on the economy during that time by the "know-nothing" political do-gooders through legislation, excessive and foolish regulation, executive order, judicial fiat and monetary policy -- and by proxy average Americans will suffer through continued high unemployment and low wage growth. I'm optimistic longer term that Americans will grow tired of this war on prosperity by the political class and will replace the bums with some pro-growth cowboys. In the meantime, the entrepreneurs always provide glimmers of hope even in the darkest times.
