Space opera has long been a staple of science fiction. Like many natural categories, it’s not that easy to define; it has something to do with interstellar travel, a variety of alien species, grand events, and a big, complicated world that stretches far beyond any particular story we might tell about it.

Star Trek is the paradigmatic example, and Star Wars also largely fits, but there are numerous of other examples, including most of my favorite science fiction worlds: Dune, the Culture, Mass Effect, Revelation Space, the Liaden, Farscape, Babylon 5, the Zones of Thought.

I think space opera is really the sort of science fiction I most enjoy. Even when it is dark, there is still something aspirational about it. Even a corrupt feudal transplanetary empire or a terrible interstellar war still means a universe where people get to travel the stars.

How likely is it that we—and I mean ‘we’ in the broad sense, humanity and its descendants—will actually get the chance to live in such a universe?

First, let’s consider the most traditional kind of space opera, the Star Trek world, where FTL is commonplace and humans interact as equals with a wide variety of alien species that are different enough to be interesting, but similar enough to be relatable.

This, sad to say, is extremely unlikely. FTL is probably impossible, or if not literally impossible then utterly infeasible by any foreseeable technology. Yes, the Alcubierre drive works in theory… all you need is tons of something that has negative mass.

And while, by sheer probability, there almost have to be other sapient lifeforms somewhere out there in this vast universe, our failure to contact or even find clear evidence of any of them for such a long period suggests that they are either short-lived or few and far between. Moreover, any who do exist are likely to be radically different from us and difficult to interact with at all, much less relate to on a personal level. Maybe they don’t have eyes or ears; maybe they live only in liquid hydrogen or molten lead; maybe they communicate entirely by pheromones that are toxic to us.

Does this mean that the aspirations of space opera are ultimately illusory? Is it just a pure fantasy that will forever be beyond us? Not necessarily.

I can see two other ways to create a very space-opera-like world, one of which is definitely feasible, and the other is very likely to be. Let’s start with the one that’s definitely feasible—indeed so feasible we will very likely get to experience it in our own lifetimes.

That is to make it a simulation. An MMO video game, in a way, but something much grander than any MMO that has yet been made. Not just EVE and No Man’s Sky, not just World of Warcraft and Minecraft and Second Life, but also Facebook and Instagram and Zoom and so much more. Oz from Summer Wars; OASIS from Ready Player One. A complete, multifaceted virtual reality in which we can spend most if not all of our lives. One complete with not just sight and sound, but also touch, smell, even taste.

Since it’s a simulation, we can make our own rules. If we want FTL and teleportation, we can have them. (And I would like to note that in fact teleportation is available in EVE, No Man’s Sky, World of Warcraft, Minecraft, and even Second Life. It’s easy to implement in a simulation, and it really seems to be something people want to have.) If we want to meet—or even be—people from a hundred different sapient species, some more humanoid than others, we can. Each of us could rule entire planets, command entire starfleets.

And we could do this, if not right now, today, then very, very soon—the VR hardware is finally maturing and the software capability already exists if there is a development team with the will and the skills (and the budget) to do it. We almost certainly will do this—in fact, we’ll do it hundreds or thousands of different ways. You need not be content with any particular space opera world, when you can choose from a cornucopia of them; and fantasy worlds too, and plenty of other kinds of worlds besides.

Yet, I admit, there is something missing from that future. While such a virtual-reality simulation might reach the point where it would be fair to say it’s no longer simply a “video game”, it still won’t be real. We won’t actually be Vulcans or Delvians or Gek or Asari. We will merely pretend to be. When we take off the VR suit at the end of the day, we will still be humans, and still be stuck here on Earth. And even if most of the toil of maintaining this society and economy can be automated, there will still be some time we have to spend living ordinary lives in ordinary human bodies.

So, is there some chance that we might really live in a space-opera future? Where we will meet actual, flesh-and-blood people who have blue skin, antennae, or six limbs? Where we will actually, physically move between planets, feeling the different gravity beneath our feet and looking up at the alien sky?

Yes. There is a way this could happen. Not now, not for awhile yet. We ourselves probably won’t live to see it. But if humanity manages to continue thriving for a few more centuries, and technology continues to improve at anything like its current pace, then that day may come.

We won’t have FTL, so we’ll be bounded by the speed of light. But the speed of light is still quite fast. It can get you to Mars in minutes, to Jupiter in hours, and even to Alpha Centauri in a voyage that wouldn’t shock Magellan or Zheng He. Leaving this arm of the Milky Way, let alone traveling to another galaxy, is out of the question (at least if you ever want to come back while anyone you know is still alive—actually as a one-way trip it’s surprisingly feasible thanks to time dilation).

This means that if we manage to invent a truly superior kind of spacecraft engine, one which combines the high thrust of a hydrolox rocket with the high specific impulse of an ion thruster—and that is physically possible, because it’s well within what nuclear rockets ought to be capable of—then we could travel between planets in our solar system, and maybe even to nearby solar systems, in reasonable amounts of time. The world of The Expanse could therefore be in reach (well, the early seasons anyway), where human colonies have settled on Mars and Ceres and Ganymede and formed their own new societies with their own unique cultures.

We may yet run into some kind of extraterrestrial life—bacteria probably, insects maybe, jellyfish if we’re lucky—but we probably ever won’t actually encounter any alien sapients. If there are any, they are probably too primitive to interact with us, or they died out millennia ago, or they’re simply too far away to reach.

But if we cannot find Vulcans and Delvians and Asari, then we can become them. We can modify ourselves with cybernetics, biotechnology, or even nanotechnology, until we remake ourselves into whatever sort of beings we want to be. We may never find a whole interplanetary empire ruled by a race of sapient felinoids, but if furry conventions are any indication, there are plenty of people who would make themselves into sapient felinoids if given the opportunity.

Such a universe would actually be more diverse than a typical space opera. There would be no “planets of hats“, no entire societies of people acting—or perhaps even looking—the same. The hybridization of different species is almost by definition impossible, but when the ‘species’ are cosmetic body mods, we can combine them however we like. A Klingon and a human could have a child—and for that matter the child could grow up and decide to be a Turian.

Honestly there are only two reasons I’m not certain we’ll go this route:

One, we’re still far too able and willing to kill each other, so who knows if we’ll even make it that long. There’s also still plenty of room for some sort of ecological catastrophe to wipe us out.

And two, most people are remarkably boring. We already live in a world where one could go to work every day wearing a cape, a fursuit, a pirate outfit, or a Starfleet uniform, and yet people don’t let you. There’s nothing infeasible about me delivering a lecture dressed as a Kzin Starfleet science officer, and nor would it even particularly impair my ability to deliver the lecture well; and yet I’m quite certain it would be greatly frowned upon if I were to do so, and could even jeopardize my career (especially since I don’t have tenure).

Would it be distracting to the students if I were to do something like that? Probably, at least at first. But once they got used to it, it might actually make them feel at ease. If it were a social norm that lecturers—and students—can dress however they like (perhaps limited by local decency regulations, though those, too, often seem overly strict), students might show up to class in bunny pajamas or pirate outfits or full-body fursuits, but would that really be a bad thing? It could in fact be a good thing, if it helps them express their own identity and makes them more comfortable in their own skin.

But no, we live in a world where the mainstream view is that every man should wear exactly the same thing at every formal occasion. I felt awkward at the AEA conference because my shirt had color.

This means that there is really one major obstacle to building the space opera future: Social norms. If we don’t get to live in this world one day, it will be because the world is ruled by the sort of person who thinks that everyone should be the same.

Pascal’s Mugging

Nov 10 JDN 2458798

In the Singularitarian community there is a paradox known as “Pascal’s Mugging”. The name is an intentional reference to Pascal’s Wager (and the link is quite apt, for reasons I’ll discuss in a later post.)

There are a few different versions of the argument; Yudkowsky’s original argument in which he came up with the name “Pascal’s Mugging” relies upon the concept of the universe as a simulation and an understanding of esoteric mathematical notation. So here is a more intuitive version:

A strange man in a dark hood comes up to you on the street. “Give me five dollars,” he says, “or I will destroy an entire planet filled with ten billion innocent people. I cannot prove to you that I have this power, but how much is an innocent life worth to you? Even if it is as little as $5,000, are you really willing to bet on ten trillion to one odds that I am lying?”

Do you give him the five dollars? I suspect that you do not. Indeed, I suspect that you’d be less likely to give him the five dollars than if he had merely said he was homeless and asked for five dollars to help pay for food. (Also, you may have objected that you value innocent lives, even faraway strangers you’ll never meet, at more than $5,000 each—but if that’s the case, you should probably be donating more, because the world’s best charities can save a live for about $3,000.)

But therein lies the paradox: Are you really willing to bet on ten trillion to one odds?

This argument gives me much the same feeling as the Ontological Argument; as Russell said of the latter, “it is much easier to be persuaded that ontological arguments are no good than it is to say exactly what is wrong with them.” It wasn’t until I read this post on GiveWell that I could really formulate the answer clearly enough to explain it.

The apparent force of Pascal’s Mugging comes from the idea of expected utility: Even if the probability of an event is very small, if it has a sufficiently great impact, the expected utility can still be large.

The problem with this argument is that extraordinary claims require extraordinary evidence. If a man held a gun to your head and said he’d shoot you if you didn’t give him five dollars, you’d give him five dollars. This is a plausible claim and he has provided ample evidence. If he were instead wearing a bomb vest (or even just really puffy clothing that could conceal a bomb vest), and he threatened to blow up a building unless you gave him five dollars, you’d probably do the same. This is less plausible (what kind of terrorist only demands five dollars?), but it’s not worth taking the chance.

But when he claims to have a Death Star parked in orbit of some distant planet, primed to make another Alderaan, you are right to be extremely skeptical. And if he claims to be a being from beyond our universe, primed to destroy so many lives that we couldn’t even write the number down with all the atoms in our universe (which was actually Yudkowsky’s original argument), to say that you are extremely skeptical seems a grievous understatement.

That GiveWell post provides a way to make this intuition mathematically precise in terms of Bayesian logic. If you have a normal prior with mean 0 and standard deviation 1, and you are presented with a likelihood with mean X and standard deviation X, what should you make your posterior distribution?

Normal priors are quite convenient; they conjugate nicely. The precision (inverse variance) of the posterior distribution is the sum of the two precisions, and the mean is a weighted average of the two means, weighted by their precision.

So the posterior variance is 1/(1 + 1/X^2).

The posterior mean is 1/(1+1/X^2)*(0) + (1/X^2)/(1+1/X^2)*(X) = X/(X^2+1).

That is, the mean of the posterior distribution is just barely higher than zero—and in fact, it is decreasing in X, if X > 1.

For those who don’t speak Bayesian: If someone says he’s going to have an effect of magnitude X, you should be less likely to believe him the larger that X is. And indeed this is precisely what our intuition said before: If he says he’s going to kill one person, believe him. If he says he’s going to destroy a planet, don’t believe him, unless he provides some really extraordinary evidence.

What sort of extraordinary evidence? To his credit, Yudkowsky imagined the sort of evidence that might actually be convincing:

If a poorly-dressed street person offers to save 10(10^100) lives (googolplex lives) for $5 using their Matrix Lord powers, and you claim to assign this scenario less than 10-(10^100) probability, then apparently you should continue to believe absolutely that their offer is bogus even after they snap their fingers and cause a giant silhouette of themselves to appear in the sky.

This post he called “Pascal’s Muggle”, after the term from the Harry Potter series, since some of the solutions that had been proposed for dealing with Pascal’s Mugging had resulted in a situation almost as absurd, in which the mugger could exhibit powers beyond our imagining and yet nevertheless we’d never have sufficient evidence to believe him.

So, let me go on record as saying this: Yes, if someone snaps his fingers and causes the sky to rip open and reveal a silhouette of himself, I’ll do whatever that person says. The odds are still higher that I’m dreaming or hallucinating than that this is really a being from beyond our universe, but if I’m dreaming, it makes no difference, and if someone can make me hallucinate that vividly he can probably cajole the money out of me in other ways. And there might be just enough chance that this could be real that I’m willing to give up that five bucks.

These seem like really strange thought experiments, because they are. But like many good thought experiments, they can provide us with some important insights. In this case, I think they are telling us something about the way human reasoning can fail when faced with impacts beyond our normal experience: We are in danger of both over-estimating and under-estimating their effects, because our brains aren’t equipped to deal with magnitudes and probabilities on that scale. This has made me realize something rather important about both Singularitarianism and religion, but I’ll save that for next week’s post.

Building a wider tent, revisited

Sep 17, JDN 2458014

At a reader’s suggestion, I am expanding upon the argument I made a few weeks ago that political coalitions are strongest when they are willing to accept some disagreement. I made that argument with numbers, which is likely to convince someone like me; but I know that many other people don’t really think that way, so it may help to provide some visuals as well.

60% of this rectangle is filled in red.

Rectangle_1

This represents the proportion of the population that agrees with you on some issue. For concreteness but to avoid making this any more political than it already is, I’m going to pick silly issues. So let’s have this first issue be about which side of the road we should drive on. Let’s say your view is that we should drive on the right. 60% of people agree that we should drive on the right. The other 40% think we should drive on the left.

Now let’s consider another issue. Let’s say this one is about putting pineapples on pizza. You, and 60% of people, agree that pineapples should not be put on pizza. The other 40% think we should put pineapples on pizza.

For now, let’s assume those two issues are independent, that someone’s opinions on driving and pizza are unrelated. Then we can fill 60% of the rectangle in blue, but it should be a perpendicular portion because the two issues aren’t related:

Rectangle_2

Those who agree with you on driving but not pizza (that would include me, by the way) are in red, those who agree with you on pizza but not driving are in blue, those who agree with you on both are in purple, and those who disagree with you on both are in white. You should already be able to see that less than half the population agrees with you on both issues, even though more than half agrees on each.

Let’s add a third issue, which we will color in green. This one can be the question of whether Star Trek is better than Star Wars. Let’s say that 60% of the population agrees with you that Star Trek is better, while 40% think that Star Wars is better. Let’s also assume that this is independent of opinions on both driving and pizza.

Rectangle_3

This is already starting to get unwieldy; there are now eight distinct regions. The white region (8) is comprised of people who disagree with you on everything. The red (6), blue (4), and green (7) regions each have people agree with you on exactly one issue. The blue-green (3), purple (2), and brown (5) regions have people agree with you on two issues. Only those in the dark-green region (1) agree with you on everything.

As you can see, the proportion of people who agree with you on all issues is fairly small, even though the majority of the population agrees with you on any given issue.

If we keep adding issues, this effect gets even stronger. I’m going to change the color-coding now to simplify things. Now, blue will indicate the people who agree with you on all issues, green the people who agree on all but one issue, yellow the people who agree on all but two issues, and red the people who disagree with you on three or more issues.

For three issues, that looks like this, which you can compare to the previous diagram:

Rectangle_4

Now let’s add a fourth issue. Let’s say 60% of people agree with you that socks should not be worn with sandals, but 40% think that socks should be worn with sandals. The blue region gets smaller:

Rectangle_5

How about a fifth issue? Let’s say 60% of people agree with you that cats are better than dogs, while 40% think that dogs are better than cats. The blue region continues to shrink:

Rectangle_6

How about a sixth issue?

Rectangle_7

And finally, a seventh issue?

Rectangle_8

Now the majority of the space is covered by red, meaning that most of the population disagrees with you on at least three issues.

To recap:

By the time there were two issues, the majority of the population disagreed with you on at least one issue.

By the time there were four issues, the majority of the population disagreed with you on at least two issues.

By the time there were seven issues, the majority of the population disagreed with you on at least three issues.

This despite the fact that the majority of the population always agrees with you on any given issue!

If you only welcomed people into your coalition who agree on every single issue (the blue region), you wouldn’t win election if there were even two issues. If you only welcomed those who disagree on at most one (blue or green), you’d stop winning if there were at least four issues. And if there were at least seven issues, you couldn’t even win by allowing those who disagree on at most two issues (blue, green, yellow).

Now, this argument very much does rely upon the different opinions being independent, which in real politics is not the case. So let’s introduce some correlations and see how this changes the result.

Suppose that once someone agrees with you about driving on the right side of the road, they are 90% likely to agree on pizza, Star Trek, sandals, and cats.

Rectangle_9
That makes things look a lot better for you; by including one level of disagreement, you could dominate every election. But notice that even in this case, if you exclude all disagreement, you will continue to lose elections.

With enough issues, even with very strong correlations you can get the same effect. Suppose there are 20 issues, and if you agree on the first one, there is a 99% chance you’ll agree on each of the others. You are still only getting about half the electorate if you don’t allow any disagreement! Due to the very high correlation, if someone disagrees with you on a few things, they usually disagree with you on many things; yet you’re still better off including some disagreement in your coalition.

Rectangle_10

Obviously, you shouldn’t include people in your coalition who actively oppose its core mission. Even if they aren’t actively trying to undermine you, at some point, the disagreement becomes so large that you’ve got to cut them loose. But in a pluralistic democracy, ideological purism is a surefire recipe for electoral failure. You need to allow at least some disagreement.

This isn’t even getting into the possibility that you might be wrong about some issues, and by including those who disagree with you, you may broaden your horizons and correct your mistakes. I’ve thus far assumed you are completely correct and in the majority on every single issue, and yet you still can’t win elections with complex policy mixes unless you include people who disagree with you.

Why is Tatooine poor?

May the Fourth be with you.

In honor of International Star Wars Day, this post is going to be about Star Wars!

[I wanted to include some images from Star Wars, but here are the copyright issues that made me decide it ultimately wasn’t a good idea.]

But this won’t be as frivolous as it may sound. Star Wars has a lot of important lessons to teach us about economics and other social sciences, and its universal popularity gives us common ground to start with. I could use Zimbabwe and Botswana as examples, and sometimes I do; but a lot of people don’t know much about Zimbabwe and Botswana. A lot more people know about Tatooine and Naboo, so sometimes it’s better to use those instead.

In fact, this post is just a small sample of a much larger work to come; several friends of mine who are social scientists in different fields (I am of course the economist, and we also have a political scientist, a historian, and a psychologist) are writing a book about this; we are going to use Star Wars as a jumping-off point to explain some real-world issues in social science.

So, my topic for today, which may end up forming the basis for a chapter of the book, is quite simple:
Why is Tatooine poor?

First, let me explain why this is such a mystery to begin with. We’re so accustomed to poverty being in the world that we expect to see it, we think of it as normal—and for most of human history, that was probably the correct attitude to have. Up until at least the Industrial Revolution, there simply was no way of raising the standard of living of most people much beyond bare subsistence. A wealthy few could sometimes live better, and most societies have had such an elite; but it was never more than about 1% of the population—and sometimes as little as 0.01%. They could have distributed wealth more evenly than they did, but there simply wasn’t that much to go around.

The “prosperous” “democracy” of Periclean Athens for example was really an aristocratic oligarchy, in which the top 1%—the ones who could read and write, and hence whose opinions we read—owned just about everything (including a fair number of the people—slavery). Their “democracy” was a voting system that only applied to a small portion of the population.

But now we live in a very different age, the Information Age, where we are absolutely basking in wealth thanks to enormous increases in productivity. Indeed, the standard of living of an Athenian philosopher was in many ways worse than that of a single mother on Welfare in the United States today; certainly the single mom has far better medicine, communication, and transportation than the philosopher, but she may even have better nutrition and higher education. Really the only things I can think of that the philosopher has more of are jewelry and real estate. The single mom also surely spends a lot more time doing housework, but a good chunk of her work is automated (dishwasher, microwave, washing machine), while the philosopher simply has slaves for that sort of thing. The smartphone in her pocket (81% of poor households in the US have a cellphone, and about half of these are smartphones) and the car in her driveway (75% of poor households in the US own at least one car) may be older models in disrepair, but they would still be unimaginable marvels to that ancient philosopher.

How is it, then, that we still have poverty in this world? Even if we argued that the poverty line in First World countries is too high because they have cars and smartphones (not an argument I agree with by the way—given our enormous productivity there’s no reason everyone shouldn’t have a car and a smartphone, and the main thing that poor people still can’t afford is housing), there are still over a billion people in the world today who live on less than $2 per day in purchasing-power-adjusted real income. That is poverty, no doubt about it. Indeed, it may in fact be a lower standard of living than most human beings had when we were hunter-gatherers. It may literally be a step downward from the Paleolithic.

Here is where Tatooine may give us some insights.

Productivity in the Star Wars universe is clearly enormous; indeed the proportional gap between Star Wars and us appears to be about the same as the proportional gap between us and hunter-gatherer times. The Death Star II had a diameter of 160 kilometers. Its cost is listed as “over 1 trillion credits”, but that’s almost meaningless because we have no idea what the exchange rate is or how the price of spacecraft varies relative to the price of other goods. (Spacecraft actually seem to be astonishingly cheap; in A New Hope it seems to be that a drink is a couple of credits while 10,000 credits is almost enough to buy an inexpensive starship. Basically their prices seem to be similar to ours for most goods, but spaceships are so cheap they are priced like cars instead of like, well, spacecraft.)

So let’s look at it another way: How much metal would it take to build such a thing, and how much would that cost in today’s money?

We actually see quite a bit of the inner structure of the Death Star II in Return of the Jedi, so I can hazard a guess that about 5% of the volume of the space station is taken up by solid material. Who knows what it’s actually made out of, but for a ballpark figure let’s assume it’s high-grade steel. The volume of a 160 km diameter sphere is 4*pi*r^3 = 4*(3.1415)*(80,000)^3 = 6.43 quadrillion cubic meters. If 5% is filled with material, that’s 320 trillion cubic meters. High-strength steel has a density of about 8000 kg/m^3, so that’s 2.6 quintillion kilograms of steel. A kilogram of high-grade steel costs about $2, so we’re looking at $5 quintillion as the total price just for the raw material of the Death Star II. That’s $5,000,000,000,000,000,000. I’m not even including the labor (droid labor, that is) and transportation costs (oh, the transportation costs!), so this is a very conservative estimate.

To get a sense of how ludicrously much money this is, the population of Coruscant is said to be over 1 trillion people, which is just about plausible for a city that covers an entire planet. The population of the entire galaxy is supposed to be about 400 quadrillion.

Suppose that instead of building the Death Star II, Emperor Palpatine had decided to give a windfall to everyone on Coruscant. How much would he have given each person (in our money)? $5 million.

Suppose instead he had offered the windfall to everyone in the galaxy? $12.50 per person. That’s 50 million worlds with an average population of 8 billion each. Instead of building the Death Star II, Palpatine could have bought the whole galaxy lunch.

Put another way, the cost I just estimated for the Death Star II is about 60 million times the current world GDP. So basically if the average world in the Empire produced as much as we currently produce on Earth, there would still not be enough to build that thing. In order to build the Death Star II in secret, it must be a small portion of the budget, maybe 5% tops. In order for only a small number of systems to revolt, the tax rates can’t be more than say 50%, if that; so total economic output on the average world in the Empire must in fact be more like 50 times what it is on Earth today, for a comparable average population. This puts their per-capita GDP somewhere around $500,000 per person per year.

So, economic output is extremely high in the Star Wars universe. Then why is Tatooine poor? If there’s enough output to make basically everyone a millionaire, why haven’t they?

In a word? Power.

Political power is of course very unequally distributed in the Star Wars universe, especially under the Empire but also even under the Old Republic and New Republic.

Core Worlds like Coruscant appear to have fairly strong centralized governments, and at least until the Emperor seized power and dissolved the Senate (as Tarkin announces in A New Hope) they also seemed to have fairly good representation in the Galactic Senate (though how you make a functioning Senate with millions of member worlds I have no idea—honestly, maybe they didn’t). As a result, Core Worlds are prosperous. Actually, even Naboo seems to be doing all right despite being in the Mid Rim, because of their strong and well-managed constitutional monarchy (“elected queen” is not as weird as it sounds—Sweden did that until the 16th century). They often talk about being a “democracy” even though they’re technically a constitutional monarchy—but the UK and Norway do the same thing with if anything less justification.

But Outer Rim Worlds like Tatooine seem to be out of reach of the central galactic government. (Oh, by the way, what hyperspace route drops you off at Tatooine if you’re going from Naboo to Coruscant? Did they take a wrong turn in addition to having engine trouble? “I knew we should have turned left at Christophsis!”) They even seem to be out of range of the monetary system (“Republic credits are no good out here,” said Watto in The Phantom Menace.), which is pretty extreme. That doesn’t usually happen—if there is a global hegemon, usually their money is better than gold. (“good as gold” isn’t strong enough—US money is better than gold, and that’s why people will accept negative real interest rates to hold onto it.) I guarantee you that if you want to buy something with a US $20 bill in Somalia or Zimbabwe, someone will take it. They might literally take it—i.e. steal it from you, and the government may not do anything to protect you—but it clearly will have value.

So, the Outer Rim worlds are extremely isolated from the central government, and therefore have their own local institutions that operate independently. Tatooine in particular appears to be controlled by the Hutts, who in turn seem to have a clan-based system of organized crime, similar to the Mafia. We never get much detail about the ins and outs of Hutt politics, but it seems pretty clear that Jabba is particularly powerful and may actually be the de facto monarch of a sizeable region or even the whole planet.

Jabba’s government is at the very far extreme of what Daron Acemoglu calls extractive regimes (I’ve been reading his tome Why Nations Fail, and while I agree with its core message, honestly it’s not very well-written or well-argued), systems of government that exist not to achieve overall prosperity or the public good, but to enrich a small elite few at the expense of everyone else. The opposite is inclusive regimes, under which power is widely shared and government exists to advance the public good. Real-world systems are usually somewhere in between; the US is still largely inclusive, but we’ve been getting more extractive over the last few decades and that’s a big problem.

Jabba himself appears to be fantastically wealthy, although even his huge luxury hover-yacht (…thing) is extremely ugly and spartan inside. I infer that he could have made it look however he wanted, and simply has baffling tastes in decor. The fact that he seems to be attracted to female humanoids is already pretty baffling, given the obvious total biological incompatibility; so Jabba is, shall we say, a weird dude. Eccentricity is quite common among despots of extractive regimes, as evidenced by Muammar Qaddafi’s ostentatious outfits, Idi Amin’s love of oranges and Kentucky Fried Chicken, and Kim Jong-Un’s fear of barbers and bond with Dennis Rodman. Maybe we would all be this eccentric if we had unlimited power, but our need to fit in with the rest of society suppresses it.

It’s difficult to put a figure on just how wealthy Jabba is, but it isn’t implausible to say that he has a million times as much as the average person on Tatooine, just as Bill Gates has a million times as much as the average person in the US. Like Qaddafi, before he was killed he probably feared that establishing more inclusive governance would only reduce his power and wealth and spread it to others, even if it did increase overall prosperity.
It’s not hard to make the figures work out so that is so. Suppose that for every 1% of the economy that is claimed by a single rentier despot, overall economic output drops by the same 1%. Then for concreteness, suppose that at optimal efficiency, the whole economy could produce $1 trillion. The amount of money that the despot can claim is determined by the portion he tries to claim, p, times the total amount that the economy will produce, which is (1-p) trillion dollars. So the despot’s wealth will be maximized when p(1-p) is maximized, which is p = 1/2; so the despot would maximize his own wealth at $250 billion if he claimed half of the economy, even though that also means that the economy produces half as much as it could. If he loosened his grip and claimed a smaller share, millions of his subjects would benefit; but he himself would lose more money than he gained. (You can also adjust these figures so that the “optimal” amount for the despot to claim is larger or smaller than half, depending on how severely the rent-seeking disrupts overall productivity.)

It’s important to note that it is not simply geography (galactography?) that makes Tatooine poor. Their sparse, hot desert may be less productive agriculturally, but that doesn’t mean that Tatooine is doomed to poverty. Indeed, today many of the world’s richest countries (such as Qatar) are in deserts, because they produce huge quantities of oil.

I doubt that oil would actually be useful in the Old Republic or the Empire, but energy more generally seems like something you’d always need. Tatooine has enormous flat desert plains and two suns, meaning that its potential to produce solar energy has to be huge. They couldn’t export the energy directly of course, but they could do so indirectly—the cheaper energy could allow them to build huge factories and produce starships at a fraction of the cost that other planets do. They could then sell these starships as exports and import water from planets where it is abundant like Naboo, instead of trying to produce their own water locally through those silly (and surely inefficient) moisture vaporators.

But Jabba likely has fought any efforts to invest in starship production, because it would require a more educated workforce that’s more likely to unionize and less likely to obey his every command. He probably has established a high tariff on water imports (or even banned them outright), so that he can maintain control by rationing the water supply. (Actually one thing I would have liked to see in the movies was Jabba being periodically doused by slaves with vats of expensive imported water. It would not only show an ostentatious display of wealth for a desert culture, but also serve the much more mundane function of keeping his sensitive gastropod skin from dangerously drying out. That’s why salt kills slugs, after all.) He also probably suppressed any attempt to establish new industries of any kind of Tatooine, fearing that with new industry could come a new balance of power.

The weirdest part to me is that the Old Republic didn’t do something about it. The Empire, okay, sure; they don’t much care about humanitarian concerns, so as long as Tatooine is paying its Imperial taxes and staying out of the Emperor’s way maybe he leaves them alone. But surely the Republic would care that this whole planet of millions if not billions of people is being oppressed by the Hutts? And surely the Republic Navy is more than a match for whatever pitiful military forces Jabba and his friends can muster, precisely because they haven’t established themselves as the shipbuilding capital of the galaxy? So why hasn’t the Republic deployed a fleet to Tatooine to unseat the Hutts and establish democracy? (It could be over pretty fast; we’ve seen that one good turbolaser can destroy Jabba’s hover-yacht—and it looks big enough to target from orbit.)

But then, we come full circle, back to the real world: Why hasn’t the US done the same thing in Zimbabwe? Would it not actually work? We sort of tried it in Libya—a lot of people died, and results are still pending I guess. But doesn’t it seem like we should be doing something?

Thus ends our zero-lower-bound interest rate policy

Not with a bang, but with a whimper.

If you are reading the blogs as they are officially published, it will have been over a week since the Federal Reserve ended its policy of zero interest rates. (If you are reading this as a Patreon Blog from the Future, it will only have been a few days.)

The official announcement was made on December 16. The Federal Funds Target Rate will be raised from 0%-0.25% to 0.25%-0.5%. That one-quarter percentage point—itself no larger than the margin of error the Fed allots itself—will make all the difference.

As pointed out in the New York Times, this is the first time nominal interest rates have been raised in almost a decade. But the Fed had been promising it for some time, and thus a major reason they did it was to preserve their own credibility. They also say they think inflation is about to hit the 2% target, though it hasn’t yet (and I was never clear on why 2% was the target in the first place).

Actually, overall inflation is currently near zero. What is at 2% is what’s called “core inflation”, which excludes particularly volatile products such as oil and food. The idea is that we want to set monetary policy based upon long-run trends in the economy as a whole, not based upon sudden dips and surges in oil prices. But right now we are in the very odd scenario of the Fed raising interest rates in order to stop inflation even as the total amount most people need to spend to maintain their standard of living is the same as it was a year ago.

As MSNBC argues, it is essentially an announcement that the Second Depression is over and the economy has now returned to normal. Of course, simply announcing such a thing does not make it true.

Personally, I think this move is largely symbolic. The difference between 0% and 0.25% is unimportant for most practical purposes.

If you owe $100,000 over 30 years at 0% interest, you will pay $277.78 per month, totaling of course $100,000. If your interest rate were raised to 0.25% interest, you would instead owe $288.35 per month, totaling $103,807.28. Even over 30 years, that 0.25% interest raises your total expenditure by less than 4%.

Over shorter terms it’s even less important. If you owe $20,000 over 5 years at 0% interest, you will pay $333.33 per month totaling $20,000. At 0.25%, you would pay $335.46 per month totaling $20,127.34, a mere 0.6% more.

Moreover, if a bank was willing to take out a loan at 0%, they’ll probably still be at 0.25%.

Where it would have the largest impact is in more exotic financial instruments, like zero-amortization or negative-amortization bonds. A zero-amortization bond at 0% is literally free money forever (assuming you can keep rolling it over). A zero-amortization bond at 0.25% means you must at least pay 0.25% of the money back each year. A negative-amortization bond at 0% makes no sense mathematically (somehow you pay back less than 0% at each payment?), while a negative-amortization bond at 0.25% only doesn’t make sense practically. If both zero and negative-amortization seem really bizarre and impossible to justify, that’s because they are. They should not exist. Most exotic financial instruments have no reason to exist, aside from the fact that they can be used to bamboozle people into giving money to the financial corporations that create them. (Which reminds me, I need to see The Big Short. But of course I have to see Star Wars: The Force Awakens first; one must have priorities.)

So, what will happen as a result of this change in interest rates? Probably not much. Inflation might go down a little—which means we might have overall deflation, and that would be bad—and the rate of increase in credit might drop slightly. In the worst-case scenario, unemployment starts to rise again, the Fed realizes their mistake, and interest rates will be dropped back to zero.

I think it’s more instructive to look at why they did this—the symbolic significance behind it.

The zero lower bound is weird. It makes a lot of economists very uncomfortable. The usual rules for how monetary and fiscal policy work break down, because the equation hits up against a constraint—a corner solution, more technically. Krugman often talks about how many of the usual ideas about how interest rates and government spending work collapse at the zero-lower-bound. We have models of this sort of thing that are pretty good, but they’re weird and counter-intuitive, so policymakers never seem to actually use them.

What is the zero lower bound, you ask? Exactly what it says on the tin. There is a lower bound on how low you can set an interest rate, and for all practical purposes that limit is zero. If you start trying to set an interest rate of -5%, people won’t be willing to loan out money and will instead hoard cash. (Interestingly, a central bank with a strong currency, such as that of the US, UK, or EU, can actually set small negative nominal interest rates—because people consider their bonds safer than cash, so they’ll pay for the safety. The ECB, Europe’s Fed, actually did so for awhile.)

The zero-lower-bound actually applies to prices in general, not just interest rates. If a product is so worthless to you that you don’t even want it if it’s free, it’s very rare for anyone to actually pay you to take it—partly because there might be nothing to stop you from taking a huge amount of it and forcing them to pay you ridiculous amounts of money. “How much is this paperclip?” “-$0.75.” “I’ll have 50 billion, please.” In a few rare cases, they might be able to pay you to take it an amount that’s less than what it costs you to store and transport. Also, if they benefit from giving it to you, companies will give you things for free—think ads and free samples. But basically, if people won’t even take something for free, that thing simply doesn’t get sold.

But if we are in a recession, we really don’t want loans to stop being made altogether. So if people are unwilling to take out loans at 0% interest, we’re in trouble. Generally what we have to do is rely on inflation to reduce the real value of money over time, thus creating a real interest rate that’s negative even though the nominal interest rate remains stuck at 0%. But what if inflation is very low? Then there’s nothing you can do except find a way to raise inflation or increase demand for credit. This means relying upon unconventional methods like quantitative easing (trying to cause inflation), or preferably using fiscal policy to spend a bunch of money and thereby increase demand for credit.

What the Fed is basically trying to do here is say that we are no longer in that bad situation. We can now set interest rates where they actually belong, rather than forcing them as low as they’ll go and hoping inflation will make up the difference.

It’s actually similar to how if you take a test and score 100%, there’s no way of knowing whether you just barely got 100%, or if you would have still done as well if the test were twice as hard—but if you score 99%, you actually scored 99% and would have done worse if the test were harder. In the former case you were up against a constraint; in the latter it’s your actual value. The Fed is essentially announcing that we really want interest rates near 0%, as opposed to being bound at 0%—and the way they do that is by setting a target just slightly above 0%.

So far, there doesn’t seem to have been much effect on markets. And frankly, that’s just what I’d expect.
