One of the more interesting economic debates in the past couple of decades is why the economy is slowing down.
Since 2000 per capita GDP growth in the US has been 0.9% per year (SRC: FRED), compared to 2.3% per year in the previous 50 years. This is a big difference: at 2.3% growth we double in wealth every generation. At 0.9% it takes us close to a century to double.
So why the slowdown?
Even fresh young blogger Ben Bernanke’s in on the game with his new blog, while George Mason’s own Tyler Cowen has written a minibook on the subject, called “The Great Stagnation.”
One thing that most economists, left and right, agree on is that it takes investment to make an economy more productive. So, naturally, economists focus on investment rates. Which have indeed come down, across most of the industrial world, mirroring the US numbers above.
To Keynesians any problem is a demand problem — it’s their one hammer to solve them all. So the position of Bernanke, Summers, the ever-present Krugman is, with minor adjustments, that there’s too much savings sloshing around in this world instead of being invested. That savings acts as a deadweight on productivity improvements.
This is completely misunderstanding how savings affect investment: a dollar saved is equivalent to temporarily removing that dollar from existence. You may as well have buried it. This means that all remaining dollars increase in value. To illustrate, let’s say you’ve got $100 billion running around the economy, and you burn $25 billion. What happens? The remaining $75 billion do the work of that original $100. Meaning each dollar rises in value, by 33%. Now, if instead of burning that money you save it instead, the impact is the same: the remaining dollars in circulation rise in value. Deflation. You still get your $100 billion spent, it’s just being accomplished with fewer pieces of paper.
So saving merely transfers purchasing power to dollars still in circulation. That Keynesian bugbear of savings gluts have no impact on investment, because they cancel themselves by purchasing-power adjustment.
So what is causing the slowdown? Cowen, who is among the few mainstream economists actually trained in Austrian economics, gets closer to what I think is the true cause, when he looks at supply-side problems. Still, I think he’s missing the obvious. Cowen claims that we have plucked the low-hanging fruit — excess land on the frontier, basic education of kids — and now we just have to suck it up and get used to the new normal.
The problem here is the timing. The frontier “closed” over a century ago, actually before the greatest leap in US economic growth (the “Gilded Age”). Literacy rates, too, leveled off a century too early. I suspect a statistical analysis would say that, by sheer coincidence, the exact opposite occured: economic growth soared once the frontier closed and literacy rates leveled off.
So what is the cause of the slowdown? Well, we need something that actually occurred in the right timeframe. For me, the problem is pretty obvious: creeping regulation. It’s hard to quantify the impact of regulations: how do measure a regulation against, say, selling street food or braiding hair without a license? So we need to use proxies.
Here’s a chart of annual number of pages in the Federal Register. This is a proxy for how many rules come up, which is in turn a proxy for the regulatory burden. These took a huge jump starting in the 1970’s, briefly interrupted by Carter’s deregulation drive, then resumed their march upwards from the 1980’s.
Comparing the productivity numbers to regulatory pages matches up pretty well: pre-1971 real GDP ran at 2.4%. Since 1971, it’s run at 1.8%. Still, the big drop-off since 2001 isn’t simply explained by pages — there was no big jump in 2000 in Federal Register pages.
So the timing’s not perfect. A lot better than the closing of the Wild West, but still it’d be nice to see more data. Specifically on the actual cost of regulations — some regulations are hugely intrusive, and some are pretty minor.
Ideally, we’d see a lot more data, and data from other countries. Because the causes of the slowdown boils down to whether it’s affecting all the countries (thus is an “environmental” factor), or if only certain countries are affected. In both the Summers-Bernanke-Krugman savings gluts and in the Cowen low-hanging-fruit explanations, they are proposing something that should be affecting at least all rich countries. In the regulations explanation, we’d expect different harm depending on the regulatory zeal of particular countries.
The data supports the country specific — regulatory — explanation, simply because there are still rich countries that are growing. The slow-down’s not affecting everybody. Here’s a chart of performance during the so-called stagnation of the top five countries in economic freedom, ranked by Heritage’s 2015 Index of Economic Freedom.
Most interesting are the three countries that actually passed the US during the supposedly world-wide stagnation: Singapore, Australia, and Switzerland. Singapore only passed the US in per capita income in 2011, Australia in 2010, and even Switzerland was the same income as the US in 2000 — and now it’s nearly 50% richer. But all these countries are catching up the the US
So what’s so special about these countries? In general, there’s almost nothing that, say, Australia, Singapore and Switzerland have in common — language, size of country, resources, structure of economy, type of government. What they do have in common, though, is low regulatory burden, limited governments, rule of law. Indeed, both Switzerland and Singapore are regularly threatened by the US as tax havens.
If, indeed, it’s this business-friendly attitude that lets some countries escape the supposed Great Stagnation, the economic prescription is very different. Rather than the expanded government role in lending, or Cowen’s pessimism, the solution is clear: put as much effort into removing regulatory and tax deadweight as we put into hatching new burdens.
