The economist Alan Blinder has just reported, “The Mystery of Declining Productivity Growth” that U.S. productivity growth has fallen dramatically in the last few years. “The healthy 2.6% a year from 1995-2010 has since been an anemic 0.4%. What’s scary is that we don’t know why.”
The economists Edward Prescott and Lee Ohanian believe the productivity slowdown is caused by a corresponding slowdown in new startups (as illustrated by the above chart). They point out, for example, that:
- The creation rate of new businesses in 2011 was 30% lower than the average rate of the 1980s.
- New startups are critical for growth since many of today’s heavyweights will decline as new businesses take their place. For example, only half of the Fortune 500 firms in 1995 remained on that list in 2010.
- Startups in high technology have also declined since 2000 even though there is no slowdown in the development of new technology.
Consistent with the recommendations of James Bessen in a recent post of mine, “Learning by Doing,” Messrs. Prescott and Ohanian recommend policy changes such as:
- Better training, plus immigration reform, to produce more skilled workers.
- Streamlining regulations that raise cost, especially for small businesses.
- Tax reform to reduce marginal tax rates.
- Reforming Dodd-Frank to make it easier for small businesses to obtain loans from main street banks.
In today’s New York Times, the economist Tyler Cowen wonders whether our economy is in the midst of a “Great Reset.” “Perhaps the most crucial issue is whether economies will return to normal conditions of steady growth, or whether we are witnessing a fundamental transformation” to a less productive economy.
Here’s another way to put it: shall we attempt to adopt better pro-growth policies or shall we just give in to the status quo and accept that we can’t do any better? Are we optimists or are we pessimists?
