How rich are we, really?

Oct 29, JDN 2458056

The most commonly-used measure of a nation’s wealth is its per-capita GDP, which is simply a total of all spending in a country divided by its population. More recently we adjust for purchasing power, giving us GDP per capita at purchasing power parity (PPP).

By this measure, the United States always does well. At most a dozen countries are above us, most of them by a small amount, and all of them are quite small countries. (For fundamental statistical reasons, we should expect both the highest and lowest average incomes to be in the smallest countries.)

But this is only half the story: It tells us how much income a country has, but not how that income is distributed. We should adjust for inequality.

How can we do this? I have devised a method that uses the marginal utility of wealth plus a measure of inequality called the Gini coefficient to work out an estimate of the average utility, instead of the average income.

I then convert back into a dollar figure. This figure is the income everyone would need to have under perfect equality, in order to give the same real welfare as the current system. That is, if we could redistribute wealth in such a way to raise everyone above this value up to it, and lower everyone above this value down to it, the total welfare of the country would not change. This provides a well-founded ranking of which country’s people are actually better off overall, accounting for both overall income and the distribution of that income.

The estimate is sensitive to the precise form I use for marginal utility, so I’ll show you comparisons for three different cases.

The “conservative” estimate uses a risk aversion parameter of 1, which means that utility is logarithmic in income. The real value of a dollar is inversely proportional to the number of dollars you already have.

The medium estimate uses a risk aversion parameter of 2, which means that the real value of a dollar is inversely proportional to the square of the number of dollars you already have.

And then the “liberal” estimate uses a risk aversion parameter of 3, which means that the real value of a dollar is inversely proportional to the cube of the number of dollars you already have.

I’ll compare ten countries, which I think are broadly representative of classes of countries in the world today.

The United States, the world hegemon which needs no introduction.

China, rising world superpower and world’s most populous country.

India, world’s largest democracy and developing economy with a long way to go.

Norway, as representative of the Scandinavian social democracies.

Germany, as representative of continental Europe.

Russia, as representative of the Soviet Union and the Second World bloc.

Saudi Arabia, as representative of the Middle East petrostates.

Botswana, as representative of African developing economies.

Zimbabwe, as representative of failed Sub-Saharan African states.

Brazil, as representative of Latin American developing economies.
The ordering of these countries by GDP per-capita PPP is probably not too surprising:

  1. Norway 69,249
  2. United States 57,436
  3. Saudi Arabia 55,158
  4. Germany 48,111
  5. Russia 26,490
  6. Botswana 17,042
  7. China 15,399
  8. Brazil 15,242
  9. India 6,616
  10. Zimbabwe 1,970

Norway is clearly the richest, the US, Saudi Arabia, and Germany are quite close, Russia is toward the upper end, Botswana, China, and Brazil are close together in the middle, and then India and especially Zimbabwe are extremely poor.

But now let’s take a look at the inequality in each country, as measured by the Gini coefficient (which ranges from 0, perfect equality, to 1, total inequality).

  1. Botswana 0.605
  2. Zimbabwe 0.501
  3. Brazil 0.484
  4. United States 0.461
  5. Saudi Arabia 0.459
  6. China 0.422
  7. Russia 0.416
  8. India 0.351
  9. Germany 0.301
  10. Norway 0.259

The US remains (alarmingly) close to Saudi Arabia by this measure. Most of the countries are between 40 and 50. But Botswana is astonishingly unequal, while Germany and Norway are much more equal.

With that in mind, let’s take a look at the inequality-adjusted per-capita GDP. First, the conservative estimate, with a parameter of 1:

  1. Norway 58700
  2. United States 42246
  3. Saudi Arabia 40632
  4. Germany 39653
  5. Russia 20488
  6. China 11660
  7. Botswana 11138
  8. Brazil 11015
  9. India 5269
  10. Zimbabwe 1405

So far, ordering of nations is almost the same compared to what we got with just per-capita GDP. But notice how Germany has moved up closer to the US and Botswana actually fallen behind China.

Now let’s try a parameter of 2, which I think is the closest to the truth:

  1. Norway 49758
  2. Germany 32683
  3. United States 31073
  4. Saudi Arabia 29931
  5. Russia 15581
  6. China 8829
  7. Brazil 7961
  8. Botswana 7280
  9. India 4197
  10. Zimbabwe 1002

Now we have seen some movement. Norway remains solidly on top, but Germany has overtaken the United States and Botswana has fallen behind not only China, but also Brazil. Russia remains in the middle, and India and Zimbawbe remain on the bottom.

Finally, let’s try a parameter of 3.

  1. Norway 42179
  2. Germany 26937
  3. United States 22855
  4. Saudi Arabia 22049
  5. Russia 11849
  6. China 6685
  7. Brazil 5753
  8. Botswana 4758
  9. India 3343
  10. Zimbabwe 715

Norway has now pulled far and away ahead of everyone else. Germany is substantially above the United States. China has pulled away from Brazil, and Botswana has fallen almost all the way to the level of India. Zimbabwe, as always, is at the very bottom.

Let’s compare this to another measure of national well-being, the Inequality-Adjusted Human Development Index (which goes from 0, the worst, to 1 the best). This index combines education, public health, and income, and adjusts for inequality. It seems to be a fairly good measure of well-being, but it’s very difficult to compile data for, so a lot of countries are missing (including Saudi Arabia); plus the precise weightings on everything are very ad hoc.

  1. Norway 0.898
  2. Germany 0.859
  3. United States 0.796
  4. Russia 0.725
  5. China 0.543
  6. Brazil 0.531
  7. India 0.435
  8. Botswana 0.433
  9. Zimbabwe 0.371

Other than putting India above Botswana, this ordering is the same as what we get from my (much easier to calculate and theoretically more well-founded) index with either a parameter of 2 or 3.

What’s more, my index can be directly interpreted: The average standard of living in the US is as if everyone were making $31,073 per year. What exactly is an IHDI index of 0.796 supposed to mean? We’re… 79.6% of the way to the best possible country?

In any case, there’s a straightforward (if not terribly surprising) policy implication here: Inequality is a big problem.

In particular, inequality in the US is clearly too high. Despite an overall income that is very high, almost 18 log points higher than Germany, our overall standard of living is actually about 5 log points lower due to our higher level of inequality. While our average income is only 19 log points lower than Norway, our actual standard of living is 47 log points lower.

Inequality in Botswana also means that their recent astonishing economic growth is not quite as impressive as it at first appeared. Many people are being left behind. While in raw income they appear to be 10 log points ahead of China and only 121 log points behind the US, once you adjust for their very high inequality they are 19 log points behind China, and 145 log points behind the US.

Of course, some things don’t change. Norway is still on top, and Zimbabwe is still on the bottom.

No, Scandinavian countries aren’t parasites. They’re just… better.

Oct 1, JDN 2457663

If you’ve been reading my blogs for awhile, you likely have noticed me occasionally drop the hashtag #ScandinaviaIsBetter; I am in fact quite enamored of the Scandinavian (or Nordic more generally) model of economic and social policy.

But this is not a consensus view (except perhaps within Scandinavia itself), and I haven’t actually gotten around to presenting a detailed argument for just what it is that makes these countries so great.

I was inspired to do this by discussion with a classmate of mine (who shall remain nameless) who emphatically disagreed; he actually seems to think that American economic policy is somewhere near optimal (and to be fair, it might actually be near optimal, in the broad space of all possible economic policies—we are not Maoist China, we are not Somalia, we are not a nuclear wasteland). He couldn’t disagree with the statistics on how wealthy and secure and happy Scandinavian countries are, so instead he came up with this: “They are parasites.”

What he seemed to mean by this is that somehow Scandinavian countries achieve their success by sapping wealth from other countries, perhaps the rest of Europe, perhaps the world more generally. On this view, it’s not that Norway and Denmark aren’t rich because they economic policy basically figured out; no, they are somehow draining those riches from elsewhere.

This could scarcely be further from the truth.

But first, consider a couple of countries that are parasites, at least partially: Luxembourg and Singapore.

Singapore has an enormous trade surplus: 5.5 billion SGD per month, which is $4 billion per month, so almost $50 billion per year. They also have a positive balance of payments of $61 billion per year. Singapore’s total GDP is about $310 billion, so these are not small amounts. What does this mean? It means that Singapore is taking in a lot more money than they are spending out. They are effectively acting as mercantilists, or if you like as a profit-seeking corporation.

Moreover, Singapore is totally dependent on trade: their exports are over $330 billion per year, and their imports are over $280 billion. You may recognize each of these figures as comparable to the entire GDP of the country. Yes, their total trade is 200% of GDP. They aren’t really so much a country as a gigantic trading company.

What about Luxembourg? Well, they have a trade deficit of 420 million Euros per month, which is about $560 million per year. Their imports total about $2 billion per year, and their exports about $1.5 billion. Since Luxembourg’s total GDP is $56 billion, these aren’t unreasonably huge figures (total trade is about 6% of GDP); so Luxembourg isn’t a parasite in the sense that Singapore is.

No, what makes Luxembourg a parasite is the fact that 36% of their GDP is due to finance. Compare the US, where 12% of our GDP is finance—and we are clearly overfinancialized. Over a third of Luxembourg’s income doesn’t involve actually… doing anything. They hold onto other people’s money and place bets with it. Even insofar as finance can be useful, it should be only very slightly profitable, and definitely not more than 10% of GDP. As Stiglitz and Krugman agree (and both are Nobel Laureate economists), banking should be boring.

Do either of these arguments apply to Scandinavia? Let’s look at trade first. Denmark’s imports total about 42 billion DKK per month, which is about $70 billion per year. Their exports total about $90 billion per year. Denmark’s total GDP is $330 billion, so these numbers are quite reasonable. What are their main sectors? Manufacturing, farming, and fuel production. Notably, not finance.

Similar arguments hold for Sweden and Norway. They may be small countries, but they have diversified economies and strong production of real economic goods. Norway is probably overly dependent on oil exports, but they are specifically trying to move away from that right now. Even as it is, only about $90 billion of their $150 billion exports are related to oil, and exports in general are only about 35% of GDP, so oil is about 20% of Norway’s GDP. Compare that to Saudi Arabia, of which has 90% of its exports related to oil, accounting for 45% of GDP. If oil were to suddenly disappear, Norway would lose 20% of their GDP, dropping their per-capita GDP… all the way to the same as the US. (Terrifying!) But Saudi Arabia would suffer a total economic collapse, and their per capita-GDP would fall from where it is now at about the same as the US to about the same as Greece.

And at least oil actually does things. Oil exporting countries aren’t parasites so much as they are drug dealers. The world is “rolling drunk on petroleum”, and until we manage to get sober we’re going to continue to need that sweet black crude. Better we buy it from Norway than Saudi Arabia.

So, what is it that makes Scandinavia so great? Why do they have the highest happiness ratings, the lowest poverty rates, the best education systems, the lowest unemployment rates, the best social mobility and the highest incomes? To be fair, in most of these not literally every top spot is held by a Scandinavian country; Canada does well, Germany does well, the UK does well, even the US does well. Unemployment rates in particular deserve further explanation, because a lot of very poor countries report surprisingly low unemployment rates, such as Cambodia and Laos.

It’s also important to recognize that even great countries can have serious flaws, and the remnants of the feudal system in Scandinavia—especially in Sweden—still contribute to substantial inequality of wealth and power.

But in general, I think if you assembled a general index of overall prosperity of a country (or simply used one that already exists like the Human Development Index), you would find that Scandinavian countries are disproportionately represented at the very highest rankings. This calls out for some sort of explanation.

Is it simply that they are so small? They are certainly quite small; Norway and Denmark each have fewer people than the core of New York City, and Sweden has slightly more people than the Chicago metropolitan area. Put them all together, add in Finland and Iceland (which aren’t quite Scandinavia), and all together you have about the population of the New York City Combined Statistical Area.

But some of the world’s smallest countries are also its poorest. Samoa and Kiribati each have populations comparable to the city of Ann Arbor and per-capita GDPs 1/10 that of the US. Eritrea is the same size as Norway, and 70 times poorer. Burundi is slightly larger than Sweden, and has a per-capita GDP PPP of only $3.14 per day.

There’s actually a good statistical reason to expect that the smallest countries should vary the most in their incomes; you’re averaging over a smaller sample so you get more variance in the estimate. But this doesn’t explain why Norway is rich and Eritrea is poor. Incomes aren’t assigned randomly. This might be a reason to try comparing Norway to specifically New York City or Los Angeles rather than to the United States as a whole (Norway still does better, in case you were wondering—especially compared to LA); but it’s not a reason to say that Norway’s wealth doesn’t really count.

Is it because they are ethnically homogeneous? Yes, relatively speaking; but perhaps not as much as you imagine. 14% of Sweden’s population is immigrants, of which 64% are from outside the EU. 10% of Denmark’s population is comprised of immigrants, of which 66% came from non-Western countries. Immigrants are 13% of Norway’s population, of which half are from non-Western countries.

That’s certainly more ethnically homogeneous than the United States; 13% of our population is immigrants, which may sound comparable, but almost all non-immigrants in Scandinavia are of indigenous Nordic descent, all “White” by the usual classification. Meanwhile the United States is 64% non-Hispanic White, 16% Hispanic, 12% Black, 5% Asian, and 1% Native American or Pacific Islander.

Scandinavian countries are actually by some measures less homogeneous than the US in terms of religion, however; only 4% of Americans are not Christian (78.5%), atheist (16.1%), or Jewish (1.7%), and only 0.6% are Muslim. As much as In Sweden, on the other hand, 60% of the population is nominally Lutheran, but 80% is atheist, and 5% of the population is Muslim. So if you think of Christian/Muslim as the sharp divide (theologically this doesn’t make a whole lot of sense, but it seems to be the cultural norm in vogue), then Sweden has more religious conflict to worry about than the US does.

Moreover, there are some very ethnically homogeneous countries that are in horrible shape. North Korea is almost completely ethnically homogeneous, for example, as is Haiti. There does seem to be a correlation between higher ethnic diversity and lower economic prosperity, but Canada and the US are vastly more diverse than Japan and South Korea yet significantly richer. So clearly ethnicity is not the whole story here.

I do think ethnic homogeneity can partly explain why Scandinavian countries have the good policies they do; because humans are tribal, ethnic homogeneity engenders a sense of unity and cooperation, a notion that “we are all in this together”. That egalitarian attitude makes people more comfortable with some of the policies that make Scandinavia what it is, which I will get into at the end of this post.

What about culture? Is there something about Nordic ideas, those Viking traditions, that makes Scandinavia better? Miles Kimball has argued this; he says we need to import “hard work, healthy diets, social cohesion and high levels of trust—not Socialism”. And truth be told, it’s hard to refute this assertion, since it’s very difficult to isolate and control for cultural variables even though we know they are important.

But this difficulty in falsification is a reason to be cautious about such a hypothesis; it should be a last resort when all the more testable theories have been ruled out. I’m not saying culture doesn’t matter; it clearly does. But unless you can test it, “culture” becomes a theory that can explain just about anything—which means that it really explains nothing.

The “social cohesion and high levels of trust” part actually can be tested to some extent—and it is fairly well supported. High levels of trust are strongly correlated with economic prosperity. But we don’t really need to “import” that; the US is already near the top of the list in countries with the highest levels of trust.

I can’t really disagree with “good diet”, except to say that almost everywhere eats a better diet than the United States. The homeland of McDonald’s and Coca-Cola is frankly quite dystopian when it comes to rates of heart disease and diabetes. Given our horrible diet and ludicrously inefficient healthcare system, the only reason we live as long as we do is that we are an extremely rich country (so we can afford to pay the most for healthcare, for certain definitions of “afford”), and almost no one here smokes anymore. But good diet isn’t so much Scandinavian as it is… un-American.

But as for “hard work”, he’s got it backwards; the average number of work hours per week is 33 in Denmark and Norway, compared to 38 in the US. Among full-time workers in the US, the average number of hours per week is a whopping 47. Working hours in the US are much more intensive than anywhere in Europe, including Scandinavia. Though of course we are nowhere near the insane work addiction suffered by most East Asian countries; lately South Korea and Japan have been instituting massive reforms to try to get people to stop working themselves to death. And not surprisingly, work-related stress is a leading cause of death in the United States. If anything, we need to import some laziness, or at least a sense of work-life balance. (Indeed, I’m fairly sure that the only reason he said “hard work” is that it’s a cultural Applause Light in the US; being against hard work is like being against the American Flag or homemade apple pie. At this point, “we need more hard work” isn’t so much an assertion as it is a declaration of tribal membership.)

But none of these things adequately explains why poverty and inequality is so much lower in Scandinavia than it is in the United States, and there’s really a quite simple explanation.

Why is it that #ScandinaviaIsBetter? They’re not afraid to make rich people pay higher taxes so they can help poor people.

In the US, this idea of “redistribution of wealth” is anathema, even taboo; simply accusing a policy of being “redistributive” or “socialist” is for many Americans a knock-down argument against that policy. In Denmark, “socialist” is a meaningful descriptor; some policies are “socialist”, others “capitalist”, and these aren’t particularly weighted terms; it’s like saying here that a policy is “Keynesian” or “Monetarist”, or if that’s too obscure, saying that it’s “liberal” or “conservative”. People will definitely take sides, and it is a matter of political importance—but it’s inside the Overton Window. It’s not almost unthinkable as it is here.

If culture has an effect here, it likely comes from Scandinavia’s long traditions of egalitarianism. Going at least back to the Vikings, in theory at least (clearly not always in practice), people—or at least fellow Scandinavians—were considered equal participants in society, no one “better” or “higher” than anyone else. Even today, it is impolite in Denmark to express pride at your own accomplishments; there’s a sense that you are trying to present yourself as somehow more deserving than others. Honestly this attitude seems unhealthy to me, though perhaps preferable to the unrelenting narcissism of American society; but insofar as culture is making Scandinavia better, it’s almost certainly because this thoroughgoing sense of egalitarianism underlies all their economic policy. In the US, the rich are brilliant and the poor are lazy; in Denmark, the rich are fortunate and the poor are unlucky. (Which theory is more accurate? Donald Trump. I rest my case.)

To be clear, Scandinavia is not communist; and they are certainly not Stalinist. They don’t believe in total collectivization of industry, or complete government control over the economy. They don’t believe in complete, total equality, or even a hard cap on wealth: Stefan Persson is an 11-figure billionaire. Does he pay high taxes, living in Sweden? Yes he does, considerably higher than he’d pay in the US. He seems to be okay with that. Why, it’s almost like his marginal utility of wealth is now negligible.

Scandinavian countries also don’t try to micromanage your life in the way often associated with “socialism”–in fact I’d say they do it less than we do in the US. Here we have Republicans who want to require drug tests for food stamps even though that literally wastes money and helps no one; there they just provide a long list of government benefits for everyone free of charge. They just held a conference in Copenhagen to discuss the possibility of transitioning many of these benefits into a basic income; and basic income is the least intrusive means of redistributing wealth.

In fact, because Scandinavian countries tax differently, it’s not necessarily the case that people always pay higher taxes there. But they pay more transparent taxes, and taxes with sharper incidence. Denmark’s corporate tax rate is only 22% compared to 35% in the US; but their top personal income tax bracket is 59% while ours is only 39.6% (though it can rise over 50% with some state taxes). Denmark also has a land value tax and a VAT, both of which most economists have clamored for for generations. (The land value tax I totally agree with; the VAT I’m a little more ambivalent about.) Moreover, filing your taxes in Denmark is not a month-long stress marathon of gathering paperwork, filling out forms, and fearing that you’ll get something wrong and be audited as it is in the US; they literally just send you a bill. You can contest it, but most people don’t. You just pay it and you’re done.

Now, that does mean the government is keeping track of your income; and I might think that Americans would never tolerate such extreme surveillance… and then I remember that PRISM is a thing. Apparently we’re totally fine with the NSA reading our emails, but God forbid the IRS just fill out our 1040s for us (that they are going to read anyway). And there’s no surveillance involved in requiring retail stores to incorporate sales tax into listed price like they do in Europe instead of making us do math at the cash register like they do here. It’s almost like Americans are trying to make taxes as painful as possible.

Indeed, I think Scandanavian socialism is a good example of how high taxes are a sign of a free society, not an authoritarian one. Taxes are a minimal incursion on liberty. High taxes are how you fund a strong government and maintain extensive infrastructure and public services while still being fair and following the rule of law. The lowest tax rates in the world are in North Korea, which has ostensibly no taxes at all; the government just confiscates whatever they decide they want. Taxes in Venezuela are quite low, because the government just owns all the oil refineries (and also uses multiple currency exchange rates to arbitrage seigniorage). US taxes are low by First World standards, but not by world standards, because we combine a free society with a staunch opposition to excessive taxation. Most of the rest of the free world is fine with paying a lot more taxes than we do. In fact, even using Heritage Foundation data, there is a clear positive correlation between higher tax rates and higher economic freedom:
Graph: Heritage Foundation Economic Freedom Index and tax burden

What’s really strange, though, is that most Americans actually support higher taxes on the rich. They often have strange or even incoherent ideas about what constitutes “rich”; I have extended family members who have said they think $100,000 is an unreasonable amount of money for someone to make, yet somehow are totally okay with Donald Trump making $300,000,000. The chant “we are the 99%” has always been off by a couple orders of magnitude; the plutocrat rentier class is the top 0.01%, not the top 1%. The top 1% consists mainly of doctors and lawyers and engineers; the top 0.01%, to a man—and they are nearly all men, in fact White men—either own corporations or work in finance. But even adjusting for all this, it seems like at least a bare majority of Americans are all right with “redistributive” “socialist” policies—as long as you don’t call them that.

So I suppose that’s sort of what I’m trying to do; don’t think of it as “socialism”. Think of it as #ScandinaviaIsBetter.

The high cost of frictional unemployment

Sep 3, JDN 2457635

I had wanted to open this post with an estimate of the number of people in the world, or at least in the US, who are currently between jobs. It turns out that such estimates are essentially nonexistent. The Bureau of Labor Statistics maintains a detailed database of US unemployment; they don’t estimate this number. We have this concept in macroeconomics of frictional unemployment, the unemployment that results from people switching jobs; but nobody seems to have any idea how common it is.

I often hear a ballpark figure of about 4-5%, which is related to a notion that “full employment” should really be about 4-5% unemployment because otherwise we’ll trigger horrible inflation or something. There is almost no evidence for this. In fact, the US unemployment rate has gotten as low as 2.5%, and before that was stable around 3%. This was during the 1950s, the era of the highest income tax rates ever imposed in the United States, a top marginal rate of 92%. Coincidence? Maybe. Obviously there were a lot of other things going on at the time. But it sure does hurt the argument that high income taxes “kill jobs”, don’t you think?

Indeed, it may well be that the rate of frictional unemployment varies all the time, depending on all sorts of different factors. But here’s what we do know: Frictional unemployment is a serious problem, and yet most macroeconomists basically ignore it.

Talk to most macroeconomists about “unemployment”, and they will assume you mean either cyclical unemployment (the unemployment that results from recessions and bad fiscal and monetary policy responses to them), or structural unemployment (the unemployment that results from systematic mismatches between worker skills and business needs). If you specifically mention frictional unemployment, the response is usually that it’s no big deal and there’s nothing we can do about it anyway.

Yet at least when we aren’t in a recession, frictional employment very likely accounts for the majority of unemployment, and thus probably the majority of misery created by unemployment. (Not necessarily, since it probably doesn’t account for much long-term unemployment, which is by far the worst.) And it is quite clear to me that there are things we can do about it—they just might be difficult and/or expensive.

Most of you have probably changed jobs at least once. Many of you have, like me, moved far away to a new place for school or work. Think about how difficult that was. There is the monetary cost, first of all; you need to pay for the travel of course, and then usually leases and paychecks don’t line up properly for a month or two (for some baffling and aggravating reason, UCI won’t actually pay me my paychecks until November, despite demanding rent starting the last week of July!). But even beyond that, you are torn from your social network and forced to build a new one. You have to adapt to living in a new place which may have differences in culture and climate. Bureaucracy often makes it difficult to change over documentation of such as your ID and your driver’s license.

And that’s assuming that you already found a job before you moved, which isn’t always an option. Many people move to new places and start searching for jobs when they arrive, which adds an extra layer of risk and difficulty above and beyond the transition itself.

With all this in mind, the wonder is that anyone is willing to move at all! And this is probably a large part of why people are so averse to losing their jobs even when it is clearly necessary; the frictional unemployment carries enormous real costs. (That and loss aversion, of course.)

What could we do, as a matter of policy, to make such transitions easier?

Well, one thing we could do is expand unemployment insurance, which reduces the cost of losing your job (which, despite the best efforts of Republicans in Congress, we ultimately did do in the Second Depression). We could expand unemployment insurance to cover voluntary quits. Right now, quitting voluntarily makes you forgo all unemployment benefits, which employers pay for in the form of insurance premiums; so an employer is much better off making your life miserable until you quit than they are laying you off. They could also fire you for cause, if they can find a cause (and usually there’s something they could trump up enough to get rid of you, especially if you’re not prepared for the protracted legal battle of a wrongful termination lawsuit). The reasoning of our current system appears to be something like this: Only lazy people ever quit jobs, and why should we protect lazy people? This is utter nonsense and it needs to go. Many states already have no-fault divorce and no-fault auto collision insurance; it’s time for no-fault employment termination.

We could establish a basic income of course; then when you lose your job your income would go down, but to a higher floor where you know you can meet certain basic needs. We could provide subsidized personal loans, similar to the current student loan system, that allow people to bear income gaps without losing their homes or paying exorbitant interest rates on credit cards.

We could use active labor market programs to match people with jobs, or train them with the skills needed for emerging job markets. Denmark has extensive active labor market programs (they call it “flexicurity”), and Denmark’s unemployment rate was 2.4% before the Great Recession, hit a peak of 6.2%, and has now recovered to 4.2%. What Denmark calls a bad year, the US calls a good year—and Greece fantasizes about as something they hope one day to achieve. #ScandinaviaIsBetter once again, and Norway fits this pattern also, though to be fair Sweden’s unemployment rate is basically comparable to the US or even slightly worse (though it’s still nothing like Greece).

Maybe it’s actually all right that we don’t have estimates of the frictional unemployment rate, because the goal really isn’t to reduce the number of people who are unemployed; it’s to reduce the harm caused by unemployment. Most of these interventions would very likely increase the rate frictional unemployment, as people who always wanted to try to find better jobs but could never afford to would now be able to—but they would dramatically reduce the harm caused by that unemployment.

This is a more general principle, actually; it’s why we should basically stop taking seriously this argument that social welfare benefits destroy work incentives. That may well be true; so what? Maximizing work incentives was never supposed to be a goal of public policy, as far as I can tell. Maximizing human welfare is the goal, and the only way a welfare program could reduce work incentives is by making life better for people who aren’t currently working, and thereby reducing the utility gap between working and not working. If your claim is that the social welfare program (and its associated funding mechanism, i.e. taxes, debt, or inflation) would make life sufficiently worse for everyone else that it’s not worth it, then say that (and for some programs that might actually be true). But in and of itself, making life better for people who don’t work is a benefit to society. Your supposed downside is in fact an upside. If there’s a downside, it must be found elsewhere.

Indeed, I think it’s worth pointing out that slavery maximizes work incentives. If you beat or kill people who don’t work, sure enough, everyone works! But that is not even an efficient economy, much less a just society. To be clear, I don’t think most people who say they want to maximize work incentives would actually support slavery, but that is the logical extent of the assertion. (Also, many Libertarians, often the first to make such arguments, do have a really bizarre attitude toward slavery; taxation is slavery, regulation is slavery, conscription is slavery—the last not quite as ridiculous—but actual forced labor… well, that really isn’t so bad, especially if the contract is “voluntary”. Fortunately some Libertarians are not so foolish.) If your primary goal is to make people work as much as possible, slavery would be a highly effective way to achieve that goal. And that really is the direction you’re heading when you say we shouldn’t do anything to help starving children lest their mothers have insufficient incentive to work.

More people not working could have a downside, if it resulted in less overall production of goods. But even in the US, one of the most efficient labor markets in the world, the system of job matching is still so ludicrously inefficient that people have to send out dozens if not hundreds of applications to jobs they barely even want, and there are still 1.4 times as many job seekers as there are openings (at the trough of the Great Recession, the ratio was 6.6 to 1). There’s clearly a lot of space here to improve the matching efficiency, and simply giving people more time to search could make a big difference there. Total output might decrease for a little while during the first set of transitions, but afterward people would be doing jobs they want, jobs they care about, jobs they’re good at—and people are vastly more productive under those circumstances. It’s quite likely that total employment would decrease, but productivity would increase so much that total output increased.

Above all, people would be happier, and that should have been our goal all along.

What Brexit means for you, Britain, and the world

July 6, JDN 2457576

It’s a stupid portmanteau, but it has stuck, so I guess I’ll suck it up and use the word “Brexit” to refer to the narrowly-successful referendum declaring that the United Kingdom will exit the European Union.

In this post I’ll try to answer one of the nagging questions that was the most googled question in the UK after the vote was finished: “What does it mean to leave the EU?”

First of all, let’s answer the second-most googled question: “What is the EU?”

The European Union is one of those awkward international institutions, like the UN, NATO, and the World Bank, that doesn’t really have a lot of actual power, but is meant to symbolize international unity and ultimately work toward forming a more cohesive international government. This is probably how people felt about national government maybe 500 years ago, when feudalism was the main system of government and nation-states hadn’t really established themselves yet. Oh, sure, there’s a King of England and all that; but what does he really do? The real decisions are all made by the dukes and the earls and whatnot. Likewise today, the EU and NATO don’t really do all that much; the real decisions are made by the UK and the US.

The biggest things that the EU does are all economic; it creates a unified trade zone called the single market that is meant to allow free movement of people and goods between countries in Europe with little if any barrier. The ultimate goal was actually to make it as unified as internal trade within the United States, but it never quite made it that far. More realistically, it’s like NAFTA, but more so, and with ten times as many countries (yet, oddly enough, almost exactly the same number of people). Starting in 1999, the EU also created the Euro, a unified national currency, which to this day remains one of the world’s strongest, most stable currencies—right up there with the dollar and the pound.

Wait, the pound? Yes, the pound. While the UK entered the EU, they did not enter the Eurozone, and therefore retained their own national currency rather than joining the Euro. One of the first pieces of fallout from Brexit was a sudden drop in the pound’s value as investors around the world got skittish about the UK’s ability to support its current level of trade.
There are in fact several layers of “EU-ness”, if you will, several levels of commitment to the project of the European Union. The strongest commitment is from the Inner Six, the six founding countries (Belgium, France, the Netherlands, Luxembourg, Italy, and Germany), followed by the aforementioned Eurozone, followed by the Schengen Area (which bans passport controls among citizens of member countries), followed by the EU member states as a whole, followed by candidate states (such as Turkey), which haven’t joined yet but are trying to. The UK was never all that fully committed to the EU to begin with; they aren’t even in the Schengen Area, much less the Eurozone. So by this vote, the UK is essentially saying that they’d dipped their toes in the water, and it was too cold, so they’re going home.

Despite the fear of many xenophobic English people (yes, specifically English—Scotland and Northern Ireland overwhelmingly voted against leaving the EU), the EU already had very little control over the UK. Though I suppose they will now have even less.

Countries in the Eurozone were subject to a lot more control, via the European Central Bank controlling their money supply. The strong Euro is great for countries like Germany and France… and one of the central problems facing countries like Portugal and Greece. Strong currencies aren’t always a good thing—they cause trade deficits. And Greece has so little influence over European monetary policy that it’s essentially as if they were pegged to someone else’s currency. But the UK really can’t use this argument, because they’ve stayed on the pound all along.

The real question is what’s going to happen to the UK’s participation in the single market. I can outline four possible scenarios, from best to worst:

  1. Brexit doesn’t actually happen: Parliament could use (some would say “abuse”) their remaining authority to override the referendum and keep the UK in the EU. After a brief period of uncertainty, everything returns to normal. Probably the best outcome, but fairly unlikely, and rather undemocratic. Probability: 10%
  2. The single market is renegotiated, making Brexit more bark than bite: At this point, a more likely way for the UK to stop the bleeding would be to leave the EU formally, but renegotiate all the associated treaties and trade agreements so that most of the EU rules about free trade, labor standards, environmental regulations, and so on actually remain in force. This would result in a brief recession in the UK as policies take time to be re-established and markets are overwhelmed by uncertainty, but its long-term economic trajectory would remain the same. The result would be similar to the current situation in Norway, and hey, #ScandinaviaIsBetter. Probability: 40%
  3. Brexit is fully carried out, but the UK remains whole: If UKIP attains enough of a mandate and a majority coalition in Parliament, they could really push through their full agenda of withdrawing from European trade. If this happens, the UK would withdraw from the single market and could implement any manner of tariffs, quotas, and immigration restrictions. Hundreds of thousands of Britons living in Europe and Europeans living in Britain would be displaced. Trade between the UK and EU would dry up. Krugman argues that it won’t be as bad as the most alarmist predictions, but it will still be pretty bad—and he definitely should know, since this is the sort of thing he got a Nobel for. The result would be a severe recession, with an immediate fall in UK GDP of somewhere between 2% and 4%, and a loss of long-run potential GDP between 6% and 8%. (For comparison, the Great Recession in the US was a loss of about 5% of GDP over 2 years.) The OECD has run a number of models on this, and the Bank of England is especially worried because they have little room to lower interest rates to fight such a recession. Their best bet would probably be to print an awful lot of pounds, but with the pound already devalued and so much national pride wrapped up in the historical strength of the pound, that seems unlikely. The result would therefore be a loss of about $85 billion in wealth immediately and more like $200 billion per year in the long run—for basically no reason. Sadly, this is the most likely scenario. Probability: 45%
  4. Balkanization of the UK: As I mentioned earlier, Scotland and Northern Ireland overwhelmingly voted against Brexit, and want no part of it. As a result, they have actually been making noises about leaving the UK if the UK decides to leave the EU. The First Minister of Scotland has proposed an “independence referendum” on Scotland leaving the UK in order to stay in the EU, and a grassroots movement in Northern Ireland is pushing for unification of all of Ireland in order to stay in the EU with the Republic of Ireland. This sort of national shake-up is basically unprecedented; parts of one state breaking off in order to stay in a larger international union? The closest example I can think of is West Germany and East Germany splitting to join NATO and the Eastern Bloc respectively, and I think we all know how well that went for East Germany. But really this is much more radical than that. NATO was a military alliance, not an economic union; nuclear weapons understandably make people do drastic things. Moreover, Germany hadn’t unified in the first place until Bismark in 1871, and thus was less than a century old when it split again. Scotland joined England to form the United Kingdom in 1707, three centuries ago, at a time when the United States didn’t even exist—indeed, George Washington hadn’t even been born. Scotland leaving the UK to stay with the EU would be like Texas leaving the US to stay in NAFTA—nay, more like Massachusetts doing that, because Scotland was a founding member of the UK and Texas didn’t become a state until 1845. While Scotland might actually be better off this way than if they go along with Brexit (and England of course even worse), this Balkanization would cast a dark shadow over all projects of international unification for decades to come, at a level far beyond what any mere Brexit could do. It would essentially mean declaring that all national unity is up for grabs, there is no such thing as a permanently unified state. I never thought I would see such a policy even being considered, much less passed; but I can’t be sure it won’t happen. My best hope is that Scotland can use this threat to keep the UK in the EU, or at least in the single market—but what if UKIP calls their bluff? Probability: 5%

Options 2 and 3 are the most likely, and actually there are intermediate cases between them; they could only implement immigration restrictions but not tariffs, for example, and that would lessen the economic fallout but still displace hundreds of thousands of people. They could only remove a few of the most stringent EU regulations, but still keep most of the good ones; that wouldn’t be so bad. Or they could be idiots and remove the good regulations (like environmental sustainability and freedom of movement) while keeping the more questionable ones (like the ban on capital controls).

Only time will tell, and the most important thing to keep in mind here is that trade is nonzero-sum. If and when England loses that $200 billion per year in trade, where will it go? Nowhere. It will disappear. That wealth—about enough to end world hunger—will simply never be created, because xenophobia reintroduced inefficiencies into the global market. Yes, it might not all disappear—Europe’s scramble for import sources and export markets could lead to say $50 billion per year in increased US trade, for example, because we’re the obvious substitute—but the net effect on the whole world will almost certainly be negative. The world will become poorer, and Britain will feel it the most.

Still, like most economists there is another emotion I’m feeling besides “What have they done!? This is terrible!”; there’s another part of my brain saying, “Wow, this is an amazing natural experiment in free trade!” Maybe the result will be bad enough to make people finally wake up about free trade, but not bad enough to cause catastrophic damage. If nothing else, it’ll give economists something to work on for years.

Should we give up on growth?

JDN 2457572

Recently I read this article published by the Post Carbon Institute, “How to Shrink the Economy without Crashing It”, which has been going around environmentalist circles. (I posted on Facebook that I’d answer it in more detail, so here goes.)

This is the far left view on climate change, which is wrong, but not nearly as wrong as even the “mainstream” right-wing view that climate change is not a serious problem and we should continue with business as usual. Most of the Republicans who ran for President this year didn’t believe in using government action to fight climate change, and Donald Trump doesn’t even believe it exists.
This core message of the article is clearly correct:

We know this because Global Footprint Network, which methodically tracks the relevant data, informs us that humanity is now using 1.5 Earths’ worth of resources.

We can temporarily use resources faster than Earth regenerates them only by borrowing from the future productivity of the planet, leaving less for our descendants. But we cannot do this for long.

To be clear, “using 1.5 Earths” is not as bad as it sounds; spending is allow to exceed income at times, as long as you have reason to think that future income will exceed future spending, and this is true not just of money but also of natural resources. You can in fact “borrow from the future”, provided you do actually have a plan to pay it back. And indeed there has been some theoretical work by environmental economists suggesting that we are rightly still in the phase of net ecological dissaving, and won’t enter the phase of net ecological saving until the mid-21st century when our technology has made us two or three times as productive. This optimal path is defined by a “weak sustainability” condition where total real wealth never falls over time, so any natural wealth depleted is replaced by at least as much artificial wealth.

Of course some things can’t be paid back; while forests depleted can be replanted, if you drive species to extinction, only very advanced technology could restore them. And we are driving thousands of species to extinction every single year. Even if we should be optimally dissaving, we are almost certainly depleting natural resources too fast, and depleting natural resources that will be difficult if not impossible to later restore. In that sense, the Post Carbon Institute is right: We must change course toward ecological sustainability.

Unfortunately, their specific ideas of how to do so leave much to be desired. Beyond ecological sustainability, they really argue for two propositions: one is radical but worth discussing, but the other is totally absurd.

The absurd claim is that we should somehow force the world to de-urbanize and regress into living in small farming villages. To show this is a bananaman and not a strawman, I quote:

8. Re-localize. One of the difficulties in the transition to renewable energy is that liquid fuels are hard to substitute. Oil drives nearly all transportation currently, and it is highly unlikely that alternative fuels will enable anything like current levels of mobility (electric airliners and cargo ships are non-starters; massive production of biofuels is a mere fantasy). That means communities will be obtaining fewer provisions from far-off places. Of course trade will continue in some form: even hunter-gatherers trade. Re-localization will merely reverse the recent globalizing trade trend until most necessities are once again produced close by, so that we—like our ancestors only a century ago—are once again acquainted with the people who make our shoes and grow our food.

9. Re-ruralize. Urbanization was the dominant demographic trend of the 20th century, but it cannot be sustained. Indeed, without cheap transport and abundant energy, megacities will become increasingly dysfunctional. Meanwhile, we’ll need lots more farmers. Solution: dedicate more societal resources to towns and villages, make land available to young farmers, and work to revitalize rural culture.

First of all: Are electric cargo ships non-starters? The Ford-class aircraft carrier is electric, specifically nuclear. Nuclear-powered cargo ships would raise a number of issues in terms of practicality, safety, and regulation, but they aren’t fundamentally infeasible. Massive efficient production of biofuels is a fantasy as long as the energy to do it is provided by coal power, but not if it’s provided by nuclear. Perhaps this author’s concept of “infeasible” really just means “infeasible if I can’t get over my irrational fear of nuclear power”. Even electric airliners are not necessarily out of the question; NASA has been experimenting with electric aircraft.

The most charitable reading I can give of this (in my terminology of argument “men”, I’m trying to make a banana out of iron), is as promoting slightly deurbanizing and going back to more like say the 1950s United States, with 64% of people in cities instead of 80% today. Even then this makes less than no sense, as higher urbanization is associated with lower per-capita ecological impact, which frankly shouldn’t even be surprising because cities have such huge economies of scale. Instead of everyone needing a car to get around in the suburbs, we can all share a subway system in the city. If that subway system is powered by a grid of nuclear, solar, and wind power, it could produce essentially zero carbon emissions—which is absolutely impossible for rural or suburban transportation. Urbanization is also associated with slower population growth (or even population decline), and indeed the reason population growth is declining is that rising standard of living and greater urbanization have reduced birth rates and will continue to do so as poor countries reach higher levels of development. Far from being a solution to ecological unsustainability, deurbanization would make it worse.

And that’s not even getting into the fact that you would have to force urban white-collar workers to become farmers, because if we wanted to be farmers we already would be (the converse is not as true), and now you’re actually talking about some kind of massive forced labor-shift policy like the Great Leap Forward. Normally I’m annoyed when people accuse environmentalists of being totalitarian communists, but in this case, I think the accusation might be onto something.

Moving on, the radical but not absurd claim is that we must turn away from economic growth and even turn toward economic shrinkage:

One way or another, the economy (and here we are talking mostly about the economies of industrial nations) must shrink until it subsists on what Earth can provide long-term.

[…]

If nothing is done deliberately to reverse growth or pre-adapt to inevitable economic stagnation and contraction, the likely result will be an episodic, protracted, and chaotic process of collapse continuing for many decades or perhaps centuries, with innumerable human and non-human casualties.

I still don’t think this is right, but I understand where it’s coming from, and like I said it’s worth talking about.

The biggest mistake here lies in assuming that GDP is directly correlated to natural resource depletion, so that the only way to reduce natural resource depletion is to reduce GDP. This is not even remotely true; indeed, countries vary almost as much in their GDP-per-carbon-emission ratio as they do in their per-capita GDP. As usual, #ScandinaviaIsBetter; Norway and Sweden produce about $8,000 in GDP per ton of carbon, while the US produces only about $2,000 per ton. Both poor and rich countries can be found among both the inefficient and the efficient. Saudi Arabia is very rich and produces about $900 per ton, while Liberia is exceedingly poor and produces about $800 per ton. I already mentioned how Norway produces $8,000 per ton, and they are as rich as Saudi Arabia. Yet above them is Mali, which produces almost $11,000 per ton, and is as poor as Liberia. Other notable facts: France is head and shoulders above the UK and Germany at almost $6000 per ton instead of $4300 and $3600 respectively—because France runs almost entirely on nuclear power.

So the real conclusion to draw from this is not that we need to shrink GDP, but that we need to make GDP more like how they do it in Norway or at least how they do it in France, rather than how we do in the US, and definitely not how they do it in Saudi Arabia. Total world emissions are currently about 36 billion tons per year, producing about $108 trillion in GDP, averaging about $3,000 of GDP per ton of carbon emissions. If we could raise the entire world to the ecological efficiency of Norway, we could double world GDP and still be producing less CO2 than we currently are. Turning the entire planet into a bunch of Norways would indeed raise CO2 output, by about a factor of 2; but it would raise standard of living by a factor of 5, and indeed bring about a utopian future with neither war nor hunger. Compare this to the prospect of cutting world GDP in half, but producing it as inefficiently as in Saudi Arabia: This would actually increase global CO2 emissions, almost as much as turning every country into Norway.

But ultimately we will in fact need to slow down or even end economic growth. I ran a little model for you, which shows a reasonable trajectory for global economic growth.

This graph shows the growth rate in productivity slowly declining, along with a much more rapidly declining GDP growth:

Solow_growth

This graph shows the growth trajectory for total real capital and GDP:

Solow_capital

And finally, this is the long-run trend for GDP graphed on a log scale:

Solow_logGDP

The units are arbitrary, though it’s not unreasonable to imagine them as being years and hundreds of dollars in per-capita GDP. If that is indeed what you imagine them to be, my model shows us the Star Trek future: In about 300 years, we rise from a per-capita GDP of $10,000 to one of $165,000—from a world much like today to a world where everyone is a millionaire.

Notice that the growth rate slows down a great deal fairly quickly; by the end of 100 years (i.e., the end of the 21st century), growth has slowed from its peak over 10% to just over 2% per year. By the end of the 300-year period, the growth rate is a crawl of only 0.1%.

Of course this model is very simplistic, but I chose it for a very specific reason: This is not a radical left-wing environmentalist model involving “limits to growth” or “degrowth”. This is the Solow-Swan model, the paradigm example of neoclassical models of economic growth. It is sometimes in fact called simply “the neoclassical growth model”, because it is that influential. I made one very small change from the usual form, which was to assume that the rate of productivity growth would decline exponentially over time. Since productivity growth is exogenous to the model, this is a very simple change to make; it amounts to saying that productivity-enhancing technology is subject to diminishing returns, which fits recent data fairly well but could be totally wrong if something like artificial intelligence or neural enhancement ever takes off.

I chose this because many environmentalists seem to think that economists have this delusional belief that we can maintain a rate of economic growth equal to today indefinitely. David Attenborough famously said “Anyone who believes in indefinite growth in anything physical, on a physically finite planet, is either mad – or an economist.”

Another physicist argued that if we increase energy consumption 2.3% per year for 400 years, we’d literally boil the Earth. Yes, we would, and no economist I know of believes that this is what will happen. Economic growth doesn’t require energy growth, and we do not think growth can or should continue indefinitely—we just think it can and should continue a little while longer. We don’t think that a world standard of living 1000 times as good as Norway is going to happen; we think that a world standard of living equal to Norway is worth fighting for.

Indeed, we are often the ones trying to explain to leaders that they need to adapt to slower growth rates—this is particularly a problem in China, where nationalism and groupthink seems to have convinced many people in China that 7% annual growth is the result of some brilliant unique feature of the great Chinese system, when it is in fact simply the expected high growth rate for an economy that is very poor and still catching up by establishing a capital base. (It’s not so much what they are doing right now, as what they were doing wrong before. Just as you feel a lot better when you stop hitting yourself in the head, countries tend to grow quite fast after they transition out of horrifically terrible economic policy—and it doesn’t get much more terrible than Mao.) Even a lot of the IMF projections are now believed to be too optimistic, because they didn’t account for how China was fudging the numbers and rapidly depleting natural resources.

Some of the specific policies recommended in the article are reasonable, while others go to far.

1. Energy: cap, reduce, and ration it. Energy is what makes the economy go, and expanded energy consumption is what makes it grow. Climate scientists advocate capping and reducing carbon emissions to prevent planetary disaster, and cutting carbon emissions inevitably entails reducing energy from fossil fuels. However, if we aim to shrink the size of the economy, we should restrain not just fossil energy, but all energy consumption. The fairest way to do that would probably be with tradable energy quotas.

I strongly support cap-and-trade on fossil fuels, but I can’t support it on energy in general, unless we get so advanced that we’re seriously concerned about significantly altering the entropy of the universe. Solar power does not have negative externalities, and therefore should not be taxed or capped.

The shift to renewable energy sources is a no-brainer, and I know of no ecologist and few economists who would disagree.

This one is rich, coming from someone who goes on to argue for nonsensical deurbanization:

However, this is a complicated process. It will not be possible merely to unplug coal power plants, plug in solar panels, and continue with business as usual: we have built our immense modern industrial infrastructure of cities, suburbs, highways, airports, and factories to take advantage of the unique qualities and characteristics of fossil fuels.

How will we make our industrial infrastructure run off a solar grid? Urbanization. When everything is in one place, you can use public transportation and plug everything into the grid. We could replace the interstate highway system with a network of maglev lines, provided that almost everyone lived in major cities that were along those lines. We can’t do that if people move out of cities and go back to being farmers.

Here’s another weird one:

Without continued economic growth, the market economy probably can’t function long. This suggests we should run the transformational process in reverse by decommodifying land, labor, and money.

“Decommodifying money”? That’s like skinning leather or dehydrating water. The whole point of money is that it is a maximally fungible commodity. I support the idea of a land tax to provide a basic income, which could go a long way to decommodifying land and labor; but you can’t decommodify money.

The next one starts off sounding ridiculous, but then gets more reasonable:

4. Get rid of debt. Decommodifying money means letting it revert to its function as an inert medium of exchange and store of value, and reducing or eliminating the expectation that money should reproduce more of itself. This ultimately means doing away with interest and the trading or manipulation of currencies. Make investing a community-mediated process of directing capital toward projects that are of unquestioned collective benefit. The first step: cancel existing debt. Then ban derivatives, and tax and tightly regulate the buying and selling of financial instruments of all kinds.

No, we’re not going to get rid of debt. But should we regulate it more? Absolutely. A ban on derivatives is strong, but shouldn’t be out of the question; it’s not clear that even the most useful derivatives (like interest rate swaps and stock options) bring more benefit than they cause harm.

The next proposal, to reform our monetary system so that it is no longer based on debt, is one I broadly agree with, though you need to be clear about how you plan to do that. Positive Money’s plan to make central banks democratically accountable, establish full-reserve banking, and print money without trying to hide it in arcane accounting mechanisms sounds pretty good to me. Going back to the gold standard or something would be a terrible idea. The article links to a couple of “alternative money theorists”, but doesn’t explain further.

Sooner or later, we absolutely will need to restructure our macroeconomic policy so that 4% or even 2% real growth is no longer the expectation in First World countries. We will need to ensure that constant growth isn’t necessary to maintain stability and full employment.

But I believe we can do that, and in any case we do not want to stop global growth just yet—far from it. We are now on the verge of ending world hunger, and if we manage to do it, it will be from economic growth above all else.

The Warren Rule is a good start

JDN 2457243 EDT 10:40.

As far back as 2010, Elizabeth Warren proposed a simple regulation on the reporting of CEO compensation that was then built into Dodd-Frank—but the SEC has resisted actually applying that rule for five years; only now will it actually take effect (and by “now” I mean over the next two years). For simplicity I’ll refer to that rule as the Warren Rule, though I don’t see a lot of other people doing that (most people don’t give it a name at all).

Two things are important to understand about this rule, which both undercut its effectiveness and make all the right-wing whinging about it that much more ridiculous.

1. It doesn’t actually place any limits on CEO compensation or employee salaries; it merely requires corporations to consistently report the ratio between them. Specifically, the rule says that every publicly-traded corporation must report the ratio between the “total compensation” of their CEO and the median salary (with benefits) of their employees; wisely, it includes foreign workers (with a few minor exceptions—lobbyists fought for more but fortunately Warren stood firm), so corporations can’t simply outsource everything but management to make it look like they pay their employees more. Unfortunately, it does not include contractors, which is awful; expect to see corporations working even harder to outsource their work to “contractors” who are actually employees without benefits (not that they weren’t already). The greatest victory here will be for economists, who now will have more reliable data on CEO compensation; and for consumers, who will now find it more salient just how overpaid America’s CEOs really are.

2. While it does wisely cover “total compensation”, that isn’t actually all the money that CEOs receive for owning and operating corporations. It includes salaries, bonuses, benefits, and newly granted stock options—it does not include the value of stock options previously exercised or dividends received from stock the CEO already owns.

TIME screwed this up; they took at face value when Larry Page reported a $1 “total compensation”, which technically is true by how “total compensation” is defined; he received a $1 token salary and no new stock awards. But Larry Page has net wealth of over $38 billion; about half of that is Google stock, so even if we ignore all others, on Google’s PE ratio of about 25, Larry Page received at least $700 million in Google retained earnings alone. (In my personal favorite unit of wealth, Page receives about 3 romneys a year in retained earnings.) No, TIME, he is not the lowest-paid CEO in the world; he has simply structured his income so that it comes entirely from owning shares instead of receiving a salary. Most top CEOs do this, so be wary when it says a Fortune 500 CEO received only $2 million, and completely ignore it when it says a CEO received only $1. Probably in the former case and definitely in the latter, their real money is coming from somewhere else.

Of course, the complaints about how this is an unreasonable demand on businesses are totally absurd. Most of them keep track of all this data anyway; it’s simply a matter of porting it from one spreadsheet to another. (I also love the argument that only “idiosyncratic investors” will care; yeah, what sort of idiot would care about income inequality or be concerned how much of their investment money is going directly to line a single person’s pockets?) They aren’t complaining because it will be a large increase in bureaucracy or a serious hardship on their businesses; they’re complaining because they think it might work. Corporations are afraid that if they have to publicly admit how overpaid their CEOs are, they might actually be pressured to pay them less. I hope they’re right.

CEO pay is set in a very strange way; instead of being based on an estimate of how much they are adding to the company, a CEO’s pay is typically set as a certain margin above what the average CEO is receiving. But then as the process iterates and everyone tries to be above average, pay keeps rising, more or less indefinitely. Anyone with a basic understanding of statistics could have seen this coming, but somehow thousands of corporations didn’t—or else simply didn’t care.

Most people around the world want the CEO-to-employee pay ratio to be dramatically lower than it is. Indeed, unrealistically lower, in my view. Most countries say only 6 to 1, while Scandinavia says only 2 to 1. I want you to think about that for a moment; if the average employee at a corporation makes $50,000, people in Scandinavia think the CEO should only make $100,000, and people elsewhere think the CEO should only make $300,000? I’m honestly not sure what would happen to our economy if we made such a rule. There would be very little incentive to want to become a CEO; why bear all that fierce competition and get blamed for everything to make only twice as much as you would as an average employee?

On the other hand, most CEOs don’t actually do all that much; CEO pay is basically uncorrelated with company performance. Maybe it would be better if they weren’t paid very much, or even if we didn’t have them at all. But under our current system, capping CEO pay also caps the pay of basically everyone else; the CEO is almost always the highest-paid individual in any corporation.

I guess that’s really the problem. We need to find ways to change the overall attitude of our society that higher authority necessarily comes with higher pay; that isn’t a rational assessment of marginal productivity, it’s a recapitulation of our primate instincts for a mating hierarchy. He’s the alpha male, of course he gets all the bananas.

The president of a university should make next to nothing compared to the top scientists at that university, because the president is a useless figurehead and scientists are the foundation of universities—and human knowledge in general. Scientists are actually the one example I can think of where one individual trulycan be one million times as productive as another—though even then I don’t think that justifies paying them one million times as much.

Most corporations should be structured so that managers make moderate incomes and the highest incomes go to engineers and designers, the people who have the highest skills and do the most important work. A car company without managers seems like an interesting experiment in employee ownership. A car company without engineers seems like an oxymoron.

Finally, people who work in finance should make very low incomes, because they don’t actually do very much. Bank tellers are probably paid about what they should be; stock traders and hedge fund managers should be paid like bank tellers. (Or rather, there shouldn’t be stock traders and hedge funds as we know them; this is all pure waste. A really efficient financial system would be extremely simple, because finance actually is very simple—people who have money loan it to people who need it, and in return receive more money later. Everything else is just elaborations on that, and most of these elaborations are really designed to obscure, confuse, and manipulate.)

Oddly enough, the place where we do this best is the nation as a whole; the President of the United States would be astonishingly low-paid if we thought of him as a CEO. Only about $450,000 including expense accounts, for a “corporation” with revenue of nearly $3 trillion? (Suppose instead we gave the President 1% of tax revenue; that would be $30 billion per year. Think about how absurdly wealthy our leaders would be if we gave them stock options, and be glad that we don’t do that.)

But placing a hard cap at 2 or even 6 strikes me as unreasonable. Even during the 1950s the ratio was about 20 to 1, and it’s been rising ever since. I like Robert Reich’s proposal of a sliding scale of corporate taxes; I also wouldn’t mind a hard cap at a higher figure, like 50 or 100. Currently the average CEO makes about 350 times as much as the average employee, so even a cap of 100 would substantially reduce inequality.
A pay ratio cap could actually be a better alternative to a minimum wage, because it can adapt to market conditions. If the economy is really so bad that you must cut the pay of most of your workers, well, you’d better cut your own pay as well. If things are going well and you can afford to raise your own pay, your workers should get a share too. We never need to set some arbitrary amount as the minimum you are allowed to pay someone—but if you want to pay your employees that little, you won’t be paid very much yourself.

The biggest reason to support the Warren Rule, however, is awareness. Most people simply have no idea of how much CEOs are actually paid. When asked to estimate the ratio between CEO and employee pay, most people around the world underestimate by a full order of magnitude.

Here are some graphs from a sampling of First World countries. I used data from this paper in Perspectives on Psychological Sciencethe fact that it’s published in a psychology journal tells you a lot about the academic turf wars involved in cognitive economics.

The first shows the absolute amount of average worker pay (not adjusted for purchasing power) in each country. Notice how the US is actually near the bottom, despite having one of the strongest overall economies and not particularly high purchasing power:

worker_pay

The second shows the absolute amount of average CEO pay in each country; I probably don’t even need to mention how the US is completely out of proportion with every other country.

CEO_pay

And finally, the ratio of the two. One of these things is not like the other ones…

CEO_worker_ratio

So obviously the ratio in the US is far too high. But notice how even in Poland, the ratio is still 28 to 1. In order to drop to the 6 to 1 ratio that most people seem to think would be ideal, we would need to dramatically reform even the most equal nations in the world. Denmark and Norway should particularly think about whether they really believe that 2 to 1 is the proper ratio, since they are currently some of the most equal (not to mention happiest) nations in the world, but their current ratios are still 48 and 58 respectively. You can sustain a ratio that high and still have universal prosperity; every adult citizen in Norway is a millionaire in local currency. (Adjusting for purchasing power, it’s not quite as impressive; instead the guaranteed wealth of a Norwegian citizen is “only” about $100,000.)

Most of the world’s population simply has no grasp of how extreme economic inequality has become. Putting the numbers right there in people’s faces should help with this, though if the figures only need to be reported to investors that probably won’t make much difference. But hey, it’s a start.
