I’ve certainly made no secret about how important monetary economics is to my thinking, but I also have never clearly laid out the arguments that convinced me of monetarism, let alone explained its central theories. This isn’t by design. There’s almost an introduction to monetarism already on this blog, if you’re willing to piece together thirty footnotes on ten different posts. It is obviously the case that no one wants to do this. Therefore, I’d like to try something else: a succinct explanation of monetary economics, written as clearly as possible and without any simplifying omissions or obfuscations, but free of (unexplained) jargon.

I have previously written about how to evaluate and think about public debt in stable, developed countries. There, the overall message was that the dangers of debt were often (but not always) overhyped and cynically used by certain politicians. In a throwaway remark, I suggested the case was rather different for developing countries. This post unpacks that remark. It looks at why things go so poorly when developing countries take on debt and lays out a set of policies that I think could help developing countries that have high debt loads.

The very first difference in debt between developed and developing countries lies in the available terms of credit; developing countries get much worse terms. This makes sense, as they’re often much more likely to default on their debt. Interest scales with risk and it just is riskier to lend money to Zimbabwe than to Canada.

But interest payments...

A friend of mine recently linked to a story about stamp scrip currencies in a discussion about Initiative Q¹. Stamp scrip currencies are an interesting monetary technology. They’re bank notes that require weekly or monthly stamps in order to be valid. These stamps cost money (normally a few percent of the face value of the note), which imposes a cost on holding the currency. This is supposed to encourage spending and spur economic activity.

This isn’t just theory. It actually happened. In the Austrian town of Wörgl, a scrip currency was used to great effect for several months during the Great Depression, leading to a sudden increase in employment, money for necessary public works, and a general reversal of fortunes that had, until that point, been quite dismal. Several other towns copied the experiment and saw similar gains, until the central bank stepped...

[Epistemic Status: Open to being convinced otherwise, but fairly confident. 11 minute read.]

As interest in how artificial intelligence will change society increases, I’ve found it revealing to note what narratives people have about the future.

Some, like the folks at MIRI and OpenAI, are deeply worried that unsafe artificial general intelligences – an artificial intelligence that can accomplish anything a person can – represent an existential threat to humankind. Others scoff at this, insisting that these are just the fever dreams of tech bros. The same news organizations that bash any talk of unsafe AI tend to believe that the real danger lies in robots taking our jobs.

Let’s express these two beliefs as separate propositions:

1. It is very unlikely that AI and AGI will pose an existential risk to human society.
2. It is very likely that AI and AGI will result in widespread unemployment.

Can you spot the contradiction between these two statements? In the common imagination, it would require an AI that can approximate human capabilities to drive significant unemployment. Given that humans are the largest existential risk to other humans (think thermonuclear war and climate change), how could equally intelligent and capable beings, bound to subservience, not present a threat?

Last week I explained how poor decisions by central bankers (specifically failing to spur inflation) can make recessions much worse and lead to slower wage growth during recovery.

(Briefly: inflation during recessions reduces the real cost of payroll, cutting business expenses and making firing people unnecessary. During a recovery, it makes hiring new workers cheaper and so leads to more being hired. Because central bankers failed to create inflation during and after the great recession, many businesses are scared of raising salaries. They believe (correctly) that this will increase their payroll expenses to the point where they’ll have to lay many people off if another recession strikes. Until memories of the last recession fade or central bankers clean up their act, we shouldn’t expect wages to rise.)

Now I’d like to expand on an offhand comment I made about the minimum wage last week and explore how it can affect recovery,...

The Economist wonders why wage growth isn’t increasing, even as unemployment falls. A naïve reading of supply and demand suggests that it should, so this has become a relatively common talking point in the news, with people of all persuasions scratching their heads. The Economist does it better than most. They at least talk about slowing productivity growth and rising oil prices, instead of blaming everything on workers (for failing to negotiate) or employers (for not suddenly raising wages).

But after reading monetary policy blogs, the current lack of wage growth feels much less confusing to me. Based on this, I’d like to offer one explanation for why wages haven’t been growing. While I may not be an economist, I’ll be doing my best to pass along verbatim the views of serious economic thinkers.
