One thought has troubled me for some time in measuring wealth and growth. In the past there was a long way to go for someone to feel wealthy. There were tangible improvements to lifespan, health, welfare, etc. associated with great wealth. Therefore increases in GDP were directly tied to the happiness of people, and tangible improvements to their lives.

What is it like when we live in a world where being a millionaire is not a particularly important accomplishment? I live in a modest neighborhood, and my neighbor is fairly wealthy. he stills lives in his modest, but greatly improved, house. He also has a vacation home in a sunnier clime. He has a nice car. But...he admits, he doesn't really have any use for most of his wealth. He literally cannot not consume enough things to diminish it, or even put a dent in it.

How does this impact GDP? When more and more people have all their modest materiel wants satisfied?

My neighbor, when he made enough money to be comfortable (not more than $5 million), stopped working for the most part. Oh he plays around a bit, but really, he doesn't work that hard. Not as hard as he did when he made his money. he is underproductive, and is an underperforming asset. he is a drag on the growth of GDP. whatever avarice he once had is gone. he has satisfied all his needs. At best he works part time.

I guess the point I'm trying to make is that accumulated wealth slows growth. Success doesn't always build on success, it can lead to stagnation. My neighbor is the very definition of doing less with more, which is not something most economists consider.

"Is there some ceiling of human productivity that we have arrived at?" Yes, based on my example, I think so. The limit is us unfortunately - how much we can or want to consume. All exponential growth curves eventually morph into S-curves.

"Sometimes, the wrong policies, centralized micromanagement, or ossified assumptions can lead to economic declines such as the Great Depression." or Venezuela. seriously, could there be a better example of how government policies and economic mismanagement can roll back prosperity? Venezuela was, for decades, a decidedly middle income country. Now it is a basket case. In less than a decade, utterly ruined.

Another strange effect of technology is people "feeling" wealthier than they truly are. For example, overseas travel used to be for the rich and famous. Then became a middle income activity with cheap jet travel. Now...with VR, anyone can see whatever part of the world they wish. Sure you could still go there, but the point is that you feel richer, that the poor can do more, experience more with even a limited income.

So I guess part of what may be hurting nominal GPD is the mere fact that it no longer accurately measures our wealth. Upper middle income people feel progressively more wealthy due to technology, and because of this take their foot off the gas, much like my neighbor did.

I guess, to summarize further, I'm saying that GDP growth is in part psychological. It is driven by human wants and desires. These are not exponential, and have quantifiable limits.

Yes, there are many limits to GDP as a metric. Even more than some people feeling wealthy (most of the ultrawealthy still work hard), part of the problem is in the manner it is calculated.

There are a variety of new products your neighbor can buy when innovation makes them available, such as household robots to clean the bathroom (replacing the person he hires), longevity treatments, self-driving cars (which will have a high premium for a while still), etc.

VR does indeed commoditize many types of recreation and experiences, as the brain will 'feel' as though the person has indeed done that thing for real. Not many understand the disruptive effect of VR on seemingly unrelated things like real estate prices, the travel industry, male-female interactions, etc.


Good article worth reading, perhaps even incorporating.


Btw, can you give an estimate from ATOM's point of view why the world GDP per capita growth has stagnated from 1994 to 2002. That was the time of personal computer s becoming mainstream and spectacular show of Moore's law. And yet the char shows a decade of virtually no growth...

It was due to the wind down and breakup of the USSR, which led to low GDP growth in all associated countries for the following decade. It was also due to a brief dollar strengthening due to cheap oil and US technology exports.

Note how GDP still reverted back to the trendline sharply thereafter. The trendline is what matters, always..


I would expect cheap oil and techno exports to be a net increase to the GDP. Do you think that it was a deflationary pressure of the technology/atom that shows reduced growth?
And a more interesting question is do we have something like that in store for the up upcoming decade?

The cheap oil strengthened the dollar briefly due to the US being the biggest oil importer by far at the time, and this is a $USD metric of GDP. So it does see short-term fluctuation due to currency rates.

PPP removes this problem, but introduces others, so the nominal ($USD) metric is still better.

For the upcoming decade, NGDP will continue to contract until the ATOM forces a major market correction that increases the level of central bank monetary expansion. Since GDP is below the trendline again (even as the trendline itself is steeper than it was in 1994-2002), we will see a reversion up. But this reversion up may require a major recession first to open the floodgates of QE..

India is the last major country to see a one-time currency gain (which China experienced 2005-12). This will increase the US$ GDP of India from $2.5T today to $10T faster than anyone thinks (just as China covered this distance in just 7-8 years)...
