In the talk, Gordon counters the commonly-held idea that economic growth is a continuous process. He makes the case that the rapid growth experienced during the last two and half centuries may have been an anomaly rather than the start of a new, everlasting historical trend.
According to Gordon, economic growth in the coming decades will slow as a result of six headwinds that will reduce future productivity and income growth. In the end, the impact of these six headwinds will leave long-term growth at half or less of the (near) 2 percent annual rate experienced between the mid-1800s and today.
The six negative headwinds that make up Gordon's "exercise in subtraction" are demography, education, inequality, globalization, energy and debt (for more, see Gordon, 2013).
My take on this issue is that I'm generally optimistic about the prospect of continued future growth but becoming somewhat pessimistic about the ability of governments to take the appropriate steps to encourage the type of innovation and technological advancements that promote robust long-term economic growth.*
As I've mentioned before, the current preoccupation of politicians and policymakers with slashing spending and reducing public debt levels is likely going to be detrimental to long-term growth. I doubt there are many growth theorists out there who would argue that trillions of dollars in lost output (as witnessed by the huge amount of idle resources, including unemployed workers) and cuts to public investment are beneficial to a nation's long-term growth prospects.
A few years ago, (the great) economist Albert Wojnilower summed up the problem that's emerged in the US with respect to government support for innovation in a 2011 interview as follows:
Gail Foster: What about the long term? There are many, maybe even a majority, who believe that we are possibly in a temporary innovation funk — maybe not so temporary. In other words, while it may be possible to be encouraged about the short term, we are just getting back to where we were before the recession, and there is not much that is economically exciting to look forward to. Would you agree?
Albert Wojnilower: I wouldn’t sell the future short. There is no lack of new business opportunities (cell phones, Facebook, electric cars, energy innovation, services that cater to aging societies). The question is, where will they be invented, used and exploited? And to whom will the benefits be distributed? The United States has traditionally been a leader in this important growth process; now it is a laggard. The shift in the U.S.’s relative position is a matter of ideology, not economics.
GF: What do you mean by ideology?
AW: The United States has adopted a free-market, small-government ideology, ostensibly copying what we did in the distant past. The difference today is that there is no frontier. Most opportunities tread on someone else’s toes (as in property rights). There is less space for greenfield experimentation. The small-government mentality means that there is no effective arbitrator of the trade-offs to break the log jam. Many of our newest “innovations” have occurred outside the traditional economic sectors — for example, creating a new sector that today we refer to as technology. Major inventions have been made by civil servants, at little personal benefit. The United States has usually been pragmatic on these matters, but now it appears to be headed in a much more dogmatic direction...
GF: Would it be fair to say that you are an optimist with respect to human ingenuity but not human nature?
AW: Yes, indeed.* For a more optimistic view, see Baily et al, the TED talk by Eric Brynjolffson and this debate between Robert Gordon and Eric Brynjolffson

The internet and computer revolution were definitely on a scale similar to the 19th century developments he mentioned. The progress that has been made on the front of data transfer and algorithmic processing is immense.
ReplyDeleteIt's hard to argue on that point but economist Ha-Joon Chang sees it somewhat differently. Here's an interesting excerpt from his 2010 book:
Delete"With the telegraph, the transmission time for a 300 word trans-Atlantic message was reduced to 7 or 8 minutes (as opposed to 2 weeks by steamship)...A reduction from 2 weeks to 7.5 minutes is by a factor of over 2500 times.
The internet reduced the transmission time of a 300-word message from 10 seconds on the fax machine to, say, 2 seconds, but this is only a reduction by a factor of 5 (for longer documents, it's longer but nowhere close to the reduction achieved by the telegraph."
Amazing stuff!
Debt is a phony, trumped-up non issue, at least at the federal level.Private debt (deleveraging)however, is still a serious problem. The elites (who fully own/bribe the politicians)want continued & GREATER austerity to widen the wealth gap, and to economically crush the 99%, via fewer social benefits and greater private indebtedness. The real purpose of austerity is to not only widen the wealth gap, but to increase the supremacy of the (parasitic) financial economy over the real economy. Say goodbye to any scheme to lesson the impact of those six headwinds, any time soon.-SteveD
ReplyDeleteGood comment, Anon. You should check out the work of economist Alan Pargues. Although, you sound like you're already acquainted with his writings.
DeleteI admire this article for the well-researched content and excellent wording. I got so involved in this material that I couldn’t stop reading. I am impressed with your work and skill. Thank you so much. www.idea-innovation-consulting.com/ideenmanagement-software/
