How (not) to talk about the defense budget

This week on Facebook I ran into a couple of memes about the defense budget that I thought were worth addressing. While the core message that the United States spends too much on the military is sound, these particular memes are so massively misleading that I think it would be irresponsible to let them go unanswered.

Tax_dollars_meme

First of all, this graph is outdated; it appears to be from about five years ago. If you use nominal figures for just direct military spending, the budget has been cut from just under $700 billion (what this figure looks like) in 2010 to only about $600 billion today. If you include verterans’ benefits, again nominally, we haven’t been below $700 billion since 2007; today we are now above $800 billion. I think the most meaningful measure is actually military spending as percent of GDP, on which we’ve cut military spending from its peak of 4.7% of GDP in 2010 to 3.5% of GDP today.

It’s also a terrible way to draw a graph; using images instead of bars may be visually appealing, but it undermines the most important aspect of a bar graph, which is that you can easily visually compare relative magnitudes.

But the most important reason why this graph is misleading is that it uses only the so-called “discretionary budget”, which includes almost all military spending but only a small fraction of spending on healthcare and social services. This creates a wildly inflated sense of how much we spend on the military relatively to other priorities.

In particular, we’re excluding Medicare and Social Security, which are on the “mandatory budget”; each of these alone is comparable to total military spending. Here’s a very nice table of all US government spending broken down by category.

Let’s just look at federal spending for now. Including veterans’ benefits, we currently spend $814 billion per year on defense. On Social Security, we spend $959 billion. On healthcare, we spend $1,018 billion per year, of which $536 billion is Medicare.

We also spend $376 billion on social welfare programs and unemployment, along with $149 billion on education, $229 billion servicing the national debt, and $214 billion on everything else (such as police, transportation, and administration).

I’ve made you a graph that accurately reflects these relative quantities:

US_federal_spending

As you can see, the military is one of our major budget items, but the largest categories are actually pensions (i.e. Social Security) and healthcare (i.e. Medicare and Medicaid).

Given the right year and properly adjusted bars on the graph, the meme may strictly be accurate about the discretionary budget, but it gives an extremely distorted sense of our overall government spending.

The next meme is even worse:

Lee_Camp_meme

Again the figures aren’t strictly wrong if you use the right year, but we’re only looking at the federal discretionary budget. Since basically all military spending is federal and discretionary, but most education spending is mandatory and done at the state and local level, this is an even more misleading picture.

Total annual US military spending (including veteran benefits) is about $815 billion.
Total US education spending (at all levels) is about $922 billion.

Here’s an accurate graph of total US government spending at all levels:

US_total_spending

That is, we spend more on education than we do on the military, and dramatically more on healthcare.

However, the United States clearly does spend far too much on the military and probably too little on education; the proper comparison to make is to other countries.

Most other First World Countries spend dramatically more on education than they do on the military.

France, for example, spends about $160 billion per year on education, but only about $53 billion per year on the military—and France is actually a relatively militaristic country, with the 6th-highest total military spending in the world.

Germany spends about $172 billion per year on education, but only about about $44 billion on the military.

In absolute figures, the United States overwhelms all other countries in the world—we spend as much as at least the next 10 combined.

Using figures from the Stockholm International Peace Research Institute (SIPRI), the US spends $610 billion of the world’s total $1,776 billion, meaning that over a third of the world’s military spending is by the United States.

This is a graph of the top 15 largest military budgets in the world.

world_military_spending

One of these things is not like the other ones…

It probably makes the most sense to compare military spending as a portion of GDP, which makes the US no longer an outlier worldwide, but still very high by First World standards:

world_military_spending_GDP

If we do want to compare military spending to other forms of spending, I think we should do that in international perspective as well. Here is a graph of education spending versus military spending as a portion of GDP, in several First World countries (military from SIPRI and the CIA, and education from the UNDP):

world_military_education

Our education spending is about average (though somehow we do it so inefficiently that we don’t provide college for free, unlike Germany, France, Finland, Sweden, or Norway), but our military spending is by far the highest.

How about a meme about that?

Elasticity and the Law of Supply

PNRJ core principles, public policy , , , , , , , , , , , , , , , ,

JDN 2457292 EDT 16:16.

Today’s post is kind of a mirror image of the previous post earlier this week; I was talking about demand before, and now I’m talking about supply. (In the next post, I’ll talk about how the two work together to determine the actual price of goods.)

Just as there is an elasticity of demand which describes how rapidly the quantity demanded changes with changes in price, likewise there is an elasticity of supply which describes how much the quantity supplied changes with changes in price.

The elasticity of supply is defined as the proportional change in quantity supplied divided by the proportional change in price; so for example if the number of cars produced increases 10% when the price of cars increases by 5%, the elasticity of supply of cars would be 10%/5% = 2.

Goods that have high elasticity of supply will rapidly flood the market if the price increases even a small amount; goods that have low elasticity of supply will sell at about the same rate as ever even if the price increases dramatically.

Generally, the more initial investment of capital a good requires, the lower its elasticity of supply is going to be.

If most of the cost of production is in the actual marginal cost of producing each new gizmo, then elasticity of supply will be high, because it’s easy to produce more or produce less as the market changes.

But if most of the cost is in building machines or inventing technologies or training employees which already has to be done in order to make any at all, while the cost of each individual gizmo is unimportant, the elasticity of supply will be low, because there’s no sense letting all that capital you invested go to waste.
We can see these differences in action by comparing different sources of electric power.

Photovoltaic solar power has a high elasticity of supply, because building new solar panels is cheap and fast. As the price of solar energy fluctuates, the amount of solar panel produced changes rapidly. Technically this is actually a “fixed capital” cost, but it’s so modular that you can install as little or as much solar power capacity as you like, which makes it behave a lot more like a variable cost than a fixed cost. As a result, a 1% increase in the price paid for solar power increases the amount supplied by a whopping 2.7%, a supply elasticity of 2.7.

Oil has a moderate elasticity of supply, because finding new oil reserves is expensive but feasible. A lot of oil in the US is produced by small wells; 18% of US oil is produced by wells that put out less than 10 barrels per day. Those small wells can be turned on and off as the price of oil changes, and new ones can be built if it becomes profitable. As a result, investment in oil production is very strongly correlated with oil prices. Still, overall production of oil changes only moderate amounts; in the US it had been steadily decreasing since 1970 until very recently when new technologies and weakened regulations resulted in a rapid increase to near-1970s levels. We sort of did hit peak oil; but it’s never quite that simple.

Nuclear fission has a very low elasticity of supply, because building a nuclear reactor is extremely expensive and requires highly advanced expertise. Building a nuclear power plant costs upward of $35 billion. Once a reactor is built, the cost of generating more power is relatively trivial; three-fourths of the cost a nuclear power plant will ever pay is paid simply to build it (or to pay back the debt incurred by doing so). Even if the price of uranium plummets or the price of oil skyrockets, it would take a long time before more nuclear power plants would be built in response.

Elasticity of supply is generally a lot larger in the long run than in the short run. Over a period of a few days or months, many types of production can’t be changed significantly. If you have a corn field, you grow as much corn as you can this season; even if the price rose substantially you couldn’t actually grow any more than your field will allow. But over a period of a year to a few years, most types of production can be changed; continuing with the corn example, you could buy new land to plant corn next season.

The Law of Supply is actually a lot closer to a true law than the Law of Demand. A negative elasticity of supply is almost unheard of; at worst elasticity of supply can sometimes drop close to zero. It really is true that elasticity of supply is almost always positive.

Land has an elasticity near zero; it’s extremely expensive (albeit not impossible; Singapore does it rather frequently) to actually create new land. As a result there’s really no good reason to ever raise the price of land; higher land prices don’t incentivize new production, they just transfer wealth to landowners. That’s why a land tax is such a good idea; it would transfer some of that wealth away from landowners and let us use it for public goods like infrastructure or research, or even just give it to the poor. A few countries actually have tried this; oddly enough, they include Singapore and Denmark, two of the few places in the world where the elasticity of land supply is appreciably above zero!

Real estate in general (which is what most property taxes are imposed on) is much trickier: In the short run it seems to have a very low elasticity, because building new houses or buildings takes a lot of time and money. But in the long run it actually has a high elasticity of supply, because there is a lot of profit to be made in building new structures if you can fund projects 10 or 15 years out. The short-run elasticity is something like 0.2, meaning a 1% increase in price only yields a 0.2% increase in supply; but the long-run elasticity may be as high as 8, meaning that a 1% increase in price yields an 8% increase in supply. This is why property taxes and rent controls seem like a really good idea at the time but actually probably have the effect of making housing more expensive. The economics of real estate has a number of fundamental differences from the economics of most other goods.

Many important policy questions ultimately hinge upon the elasticity of supply: If elasticity is high, then taxing or regulating something is likely to cause large distortions of the economy, while if elasticity is low, taxes and regulations can be used to support public goods or redistribute wealth without significant distortion to the economy. On the other hand, if elasticity is high, markets generally function well on their own, while if elasticity is low, prices can get far out of whack. As a general rule of thumb, government intervention in markets is most useful and most necessary when elasticity is low.

Elasticity and the Law of Demand

PNRJ core principles, critique of neoclassical economics , , , , , , , , ,

JDN 2457289 EDT 21:04

This will be the second post in my new bite-size format, the first one that’s in the middle of the week.

I’ve alluded previously to the subject of demand elasticity, but I think it’s worth explaining in a little more detail. The basic concept is fairly straightforward: Demand is more elastic when the amount that people want to buy changes a large amount for a small change in price. The opposite is inelastic.

Apples are a relatively elastic good. If the price of apples goes up, people buy fewer apples. Maybe they buy other fruit instead, such as oranges or bananas; or maybe they give up on fruit and eat something else, like rice.

Salt is an extremely inelastic good. No matter what the price of salt is, at least within the range it has been for the last few centuries, people are going to continue to buy pretty much the same amount of salt. (In ancient times salt was actually expensive enough that people couldn’t afford enough of it, which was particularly harmful in desert regions. Mark Kulansky’s book Salt on this subject is surprisingly compelling, given the topic.)
Specifically, the elasticity is equal to the proportional change in quantity demanded, divided by the proportional change in price.

For example, if the price of gas rises from $2 per gallon to $3 per gallon, that’s a 50% increase. If the quantity of gas purchase then falls from 100 billion gallons to 90 billion gallons, that’s a 10% decrease. If increasing the price by 50% decreased the quantity demanded by 10%, that would be a demand elasticity of -10%/50% = -1/5 = -0.2

In practice, measuring elasticity is more complicated than that, because supply and demand are both changing at the same time; so when we see a price change and a quantity change, it isn’t always clear how much of each change is due to supply and how much is due to demand. Sophisticated econometric techniques have been developed to try to separate these two effects (in future posts I plan to explain the basics of some of these techniques), but it’s difficult and not always successful.

In general, markets function better when supply and demand are more elastic. When shifts in price trigger large shifts in quantity, this creates pressure on the price to remain at a fixed level rather than jumping up and down. This in turn means that the market will generally be predictable and stable.

It’s also much harder to make monopoly profits in a market with elastic demand; even if you do have a monopoly, if demand is highly elastic then raising the price won’t make you any money, because whatever you gain in selling each gizmo for more, you’ll lose in selling fewer gizmos. In fact, the profit margin for a monopoly is inversely proportional to the elasticity of demand.

Markets do not function well when supply and demand are highly inelastic. Monopolies can become very powerful and result in very large losses of human welfare. A particularly vivid example of this was in the news recently, when a company named Turing purchased the rights to a drug called Daraprim used primarily by AIDS patients, then hiked the price from $13.50 to $750. This made enough people mad that the CEO has since promised to bring it back down, though he hasn’t said how far.

That price change was only possible because Daraprim has highly inelastic demand—if you’ve got AIDS, you’re going to take AIDS medicine, as much as prescribed, provided only that it doesn’t drive you completely bankrupt. (Not an unreasonable fear, as medical costs are the leading cause of bankruptcy in the United States.) This raised price probably would bankrupt a few people, but for the most part it wouldn’t affect the amount of drug sold; it would just funnel a huge amount of money from AIDS patients to the company. This is probably part of why it made people so mad; that and there would probably be a few people who died because they couldn’t afford this new expensive medication.

Imagine if a company had tried to pull the same stunt for a more elastic good, like apples. “CEO buys up all apple farms, raises price of apples from $2 per pound to $100 per pound.” What’s going to happen then? People are not going to buy any apples. Perhaps a handful of the most die-hard apple lovers still would, but the rest of us are going to meet our fruit needs elsewhere.

For most goods most of the time, elasticity of demand is negative, meaning that as price increases, quantity demanded decreases. This is in fact called the Law of Demand; but as I’ve said, “laws” in economics are like the Pirate Code: They’re really more what you’d call “guidelines”.
There are three major exceptions to the Law of Demand. The first one is the one most economists talk about, and it almost never happens. The second one is talked about occasionally, and it’s quite common. The third one is almost never talked about, and yet it is by far the most common and one of the central driving forces in modern capitalism.
The exception that we usually talk about in economics is called the Giffen Effect. A Giffen good is a good that’s so cheap and such a bare necessity that when it becomes more expensive, you won’t be able to buy less of it; instead you’ll buy more of it, and buy less of other things with your reduced income.

It’s very hard to come up with empirical examples of Giffen goods, but it’s an easy theoretical argument to make. Suppose you’re buying grapes for a party, and you know you need 4 bags of grapes. You have $10 to spend. Suppose there are green grapes selling for $1 per bag and red grapes selling for $4 per bag, and suppose you like red grapes better. With your $10, you can buy 2 bags of green grapes and 2 bags of red grapes, and that’s the 4 bags you need. But now suppose that the price of green grapes rises to $2 per bag. In order to afford 4 bags of grapes, you now need to buy 3 bags of green grapes and only 1 bag of red grapes. Even though it was the price of green grapes that rose, you ended up buying more green grapes. In this scenario, green grapes are a Giffen good.

The exception that is talked about occasionally and occurs a lot in real life is the Veblen Effect. Whereas a Giffen good is a very cheap bare necessity, a Veblen good is a very expensive pure luxury.

The whole point of buying a Veblen good is to prove that you can. You don’t buy a Ferrari because a Ferrari is a particularly nice automobile (a Prius is probably better, and a Tesla certainly is); you buy a Ferrari to show off that you’re so rich you can buy a Ferrari.

On my previous post, jenszorn asked: “Much of consumer behavior is irrational by your standards. But people often like to spend money just for the sake of spending and for showing off. Why else does a Rolex carry a price tag for $10,000 for a Rolex watch when a $100 Seiko keeps better time and requires far less maintenance?” Veblen goods! It’s not strictly true that Veblen goods are irrational; it can be in any particular individual’s best interest is served by buying Veblen goods in order to signal their status and reap the benefits of that higher status. However, it’s definitely true that Veblen goods are inefficient; because ostentatious displays of wealth are a zero-sum game (it’s not about what you have, it’s about what you have that others don’t), any resources spent on rich people proving how rich they are are resources that society could otherwise have used, say, feeding the poor, curing diseases, building infrastructure, or colonizing other planets.

Veblen goods can also result in a violation of the Law of Demand, because raising the price of a Veblen good like Ferraris or Rolexes can make them even better at showing off how rich you are, and therefore more appealing to the kind of person who buys them. Conversely, lowering the price might not result in any more being purchased, because they wouldn’t seem as impressive anymore. Currently a Ferrari costs about $250,000; if they reduced that figure to $100,000, there aren’t a lot of people who would suddenly find it affordable, but many people who currently buy Ferraris might switch to Bugattis or Lamborghinis instead. There are limits to this, of course: If the price of a Ferrari dropped to $2,000, people wouldn’t buy them to show off anymore; but the far larger effect would be the millions of people buying them because you can now get a perfectly good car for $2,000. Yes, I would sell my dear little Smart if it meant I could buy a Ferrari instead and save $8,000 at the same time.

But the third major exception to the Law of Demand is actually the most important one, yet it’s the one that economists hardly ever talk about: Speculation.

The most common reason why people would buy more of something that has gotten more expensive is that they expect it to continue getting more expensive, and then they will be able to sell what they bought at an even higher price and make a profit.

When the price of Apple stock goes up, do people stop buying Apple stock? On the contrary, they almost certainly start buying more—and then the price goes up even further still. If rising prices get self-fulfilling enough, you get an asset bubble; it grows and grows until one day it can’t, and then the bubble bursts and prices collapse again. This has happened hundreds of times in history, from the Tulip Mania to the Beanie Baby Bubble to the Dotcom Boom to the US Housing Crisis.

It isn’t necessarily irrational to participate in a bubble; some people must be irrational, but most people can buy above what they would be willing to pay by accurately predicting that they’ll find someone else who is willing to pay an even higher price later. It’s called Greater Fool Theory: The price I paid may be foolish, but I’ll find someone who is even more foolish to take it off my hands. But like Veblen goods, speculation goods are most definitely inefficient; nothing good comes from prices that rise and fall wildly out of sync with the real value of goods.

Speculation goods are all around us, from stocks to gold to real estate. Most speculation goods also serve some other function (though some, like gold, are really mostly just Veblen goods otherwise; actual useful applications of gold are extremely rare), but their speculative function often controls their price in a way that dominates all other considerations. There’s no real limit to how high or low the price can go for a speculation good; no longer tied to the real value of the good, it simply becomes a question of how much people decide to pay.

Indeed, speculation bubbles are one of the fundamental problems with capitalism as we know it; they are one of the chief causes of the boom-and-bust business cycle that has cost the world trillions of dollars and thousands of lives. Most of our financial industry is now dedicated to the trading of speculation goods, and finance is taking over a larger and larger section of our economy all the time. Many of the world’s best and brightest are being funneled into finance instead of genuinely productive industries; 15% of Harvard grads take a job in finance, and almost half did just before the crash. The vast majority of what goes on in our financial system is simply elaborations on speculation; very little real productivity ever enters into the equation.

In fact, as a general rule I think when we see a violation of the Law of Demand, we know that something is wrong in the economy. If there are Giffen goods, some people are too poor to buy what they really need. If there are Veblen goods, inequality is too large and people are wasting resources competing for status. And since there are always speculation goods, the history of capitalism has been a history of market instability.

Fortunately, elasticity of demand is usually negative: As the price goes up, people want to buy less. How much less is the elasticity.

Advertising: Someone is being irrational

PNRJ critique of neoclassical economics, public policy , , , , , , , , , , , , , , ,

JDN 2457285 EDT 12:52

I’m working on moving toward a slightly different approach to posting; instead of one long 3000-word post once a week, I’m going to try to do two more bite-sized posts of about 1500 words or less spread throughout the week. I’m actually hoping to work toward setting up a Patreon and making blogging into a source of income.

Today’s bite-sized post is about advertising, and a rather simple, basic argument that shows that irrational economic behavior is widespread.

First, there are advertisements that don’t make sense. They don’t tell you anything about the product, they are often completely absurd, and while sometimes entertaining they are rarely so entertaining that people would pay to see them in theaters or buy them on DVD—which means that any entertainment value they had is outweighed by the opportunity cost of seeing them instead of the actual TV show, movie, or whatever else it was you wanted to see.

If you doubt that there are advertisements that don’t make sense, I have one example in particular for you which I think will settle this matter:

If you didn’t actually watch it, you must. It is too absurd to be explained.

And of course there are many other examples, from Coca-Cola’s weird associations with polar bears to the series of GEICO TV spots about Neanderthals that they thought were so entertaining as to deserve a TV show (the world proved them wrong), to M&M commercials that present a terrifying world in which humans regularly consume the chocolatey flesh of other sapient citizens (and I thought beef was bad!).

Or here’s another good one:

In the above commercial, Walmart attempts to advertise themselves by showing a heartwarming story of a child who works hard to make money by doing odd jobs, including using the model of door-to-door individual sales that Walmart exists to make obsolete. The only contribution Walmart makes to the story is apparently “we have affordable bicycles for children”. Coca-Cola is also thrown in for some reason.

Certain products seem to attract nonsensical advertising more than others, with car insurance being the prime culprit of totally nonsensical and irrelevant commercials, perhaps because of GEICO in particular who do not actually seem to be any good at providing car insurance but instead spend all of their resources making commercials.

Commercials for cars themselves are an interesting case, as certain ads actually appeal in at least a general way to the quality of the vehicle itself:

Then there are those that vaguely allude to qualities of their vehicles, but mostly immerse us in optimistic cyberpunk:

Others, however, make no attempt to say anything about the vehicle, instead spinning us exciting tales of giant hamsters who use the car and the power of dance to somehow form a truce between warring robot factions in a dystopian future (if you haven’t seen this commercial, none of that is a joke; see for yourself below):

So, I hope that I have satisfied you that there are in fact advertisements which don’t make sense, which could not possibly give anyone a rational reason to purchase the product contained within.

Therefore, at least one of the following statements must be true:

1. Consumers behave irrationally by buying products for irrational reasons
2. Corporations behave irrationally by buying advertisements that don’t work

Both could be true (in fact I think both are true), but at least one must be, on pain of contradiction, as long as you accept that there are advertisements which don’t provide rational reasons to buy products. There’s no wiggling out of this one, neoclassicists.

Advertising forms a large part of our economy—Americans spend $171 billion per year on ads, more than the federal government spends on education, and also more than the nominal GDP of Hungary or Vietnam. This figure is growing thanks to the Internet and its proliferation of “free” ad-supported content. Insofar as advertising is irrational, this money is being thrown down the drain.

The waste from spending on ads that don’t work is limited; you can’t waste more than you actually spent. But the waste from buying things you don’t actually need is not limited in the same way; an ad that cost $1 million to air (cheaper than a typical Super Bowl ad) could lead to $10 million in worthless purchases.

I wouldn’t say that all advertising is irrational; some ads do actually provide enough meaningful information about a product that they could reasonably motivate you to buy it (or at least look into buying it), and it is in both your best interest and the company’s best interest for you to have such information.

But I think it’s not unreasonable to estimate that about half of our advertising spending is irrational, either by making people buy things for bad reasons or by making corporations waste time and money on buying ads that don’t work. This amounts to some $85 billion per year, or enough to pay every undergraduate tuition at every public university in the United States.

This state of affairs is not inevitable.

Most meaningless ads could be undermined by regulation; instead of the current “blacklist” model where an ad is legal as long as it doesn’t explicitly state anything that is verifiably false, we could move to a “whitelist” model where an ad is illegal if it states anything that isn’t verifiably true. Red Bull cannot give you wings, Maxwell House isn’t good to the last drop, and Volkswagen needs to be more specific than “round for a reason”. We may never be able to completely eliminate irrelevant emotionally-salient allusions (pictures of families, children, puppies, etc.), but as long as the actual content of the words is regulated it would be much harder to deluge people with advertisements that provide no actual information.

We have a choice, as a civilization: Do we want to continue to let meaningless ads invade our brains and waste the resources of our society?

9/11, 14 years on—and where are our civil liberties?

PNRJ public policy , , , , , , , , , , , , , , , , , ,

JDN 2457278 (09/11/2015) EDT 20:53

Today is the 14th anniversary of the 9/11 attacks. A lot has changed since then—yet it’s quite remarkable what hasn’t. In particular, we still don’t have our civil liberties back.

In our immediate panicked response to the attacks, the United States passed almost unanimously the USA PATRIOT ACT, giving unprecedented power to our government in surveillance, searches, and even arrests and detentions. Most of those powers have been renewed repeatedly and remain in effect; the only major change has been a slight weakening of the NSA’s authority to use mass dragnet surveillance on Internet traffic and phone metadata. And this change in turn was almost certainly only made because of Edward Snowden, who is still forced to live in Russia for fear of being executed if he returns to the US. That is, the man most responsible for the only significant improvement in civil liberties in the United States in the last decade is living in Russia because he has been branded a traitor. No, the traitors here are the over one hundred standing US Congress members who voted for an act that is in explicit and direct violation of the Constitution. At the very least every one of them should be removed from office, and we as voters have the power to do that—so why haven’t we? In particular, why are Dan Lipinski and Steny Hoyer, both Democrats from non-southern states who voted every single time to extend provisions of the PATRIOT ACT, still in office? At least Carl Levin had the courtesy to resign after sponsoring the act allowing indefinite detention—I hope we would have voted him out anyway, since I’d much rather have a Republican (and all the absurd economic policy that entails) than someone who apparently doesn’t believe the Fourth and Sixth Amendments have any meaning at all.

We have become inured to this loss of liberty; it feels natural or inevitable to us. But these are not minor inconveniences; they are not small compromises. Giving our government the power to surveil, search, arrest, imprison, torture, and execute anyone they want at any time without the system of due process—and make no mistake, that is what the PATRIOT ACT and the indefinite detention law do—means giving away everything that separates us from tyranny. Bypassing the justice system and the rule of law means bypassing everything that America stands for.

So far, these laws have actually mostly been used against people reasonably suspected of terrorism, that much is true; but it’s also irrelevant. Democracy doesn’t mean you give the government extreme power and they uphold your trust and use it benevolently. Democracy means you don’t give them that power in the first place.

If there’s really sufficient evidence to support an arrest for terrorism, get a warrant. If you don’t have enough evidence for a warrant, you don’t have enough evidence for an arrest. If there’s really sufficient evidence to justify imprisoning someone for terrorism, get a jury to convict. If you don’t have enough evidence to convince a jury, guess what? You don’t have enough evidence to imprison them. These are not negotiable. They are not “political opinions” in any ordinary sense. The protection of due process is so fundamental to democracy that without it political opinions lose all meaning.

People talk about “Big Government” when we suggest increasing taxes on capital gains or expanding Medicare. No, that isn’t Big Government. Searching without warrants is Big Government. Imprisoning people without trial is Big Government. From all the decades of crying wolf in which any policy someone doesn’t like is accused of being “tyranny”, we seem to have lost the ability to recognize actual tyranny. I hope you understand the full force of my meaning when I say that the PATRIOT ACT is literally fascist. Fascism has come to America, and as predicted it was wrapped in the flag and carrying a cross.

In this sort of situation, a lot of people like to quote (or misquote) Benjamin Franklin:

“Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.”

With the qualifiers “essential” and “temporary”, this quote seems right; but a lot of people forget them and quote him as saying:
“Those would give up liberty to purchase safety, deserve neither liberty nor safety.”

That’s clearly wrong. We do in fact give up liberty to purchase safety, and as well we should. We give up our liberty to purchase weapons-grade plutonium; we give up our liberty to drive at 220 mph. The question we need to be asking is: How much liberty are we giving up to gain how much safety?

Spoken like an economist, the question is not whether you will give up liberty to purchase safety—the question is at what price you’re willing to make the purchase. The price we’ve been paying in response to terrorism is far too high. Indeed, the price we are paying is tantamount to America itself.

As horrific as 9/11 was, it’s important to remember: It only killed 3,000 people.

This statement probably makes you uncomfortable; it may even offend you. How dare I say “only”?

I don’t mean to minimize the harm of those deaths. I don’t mean to minimize the suffering of people who lost friends, colleagues, parents, siblings, children. The death of any human being is the permanent destruction of something irreplaceable, a spark of life that can never be restored; it is always a tragedy and there is never any way to repay it.

But I think people are actually doing the opposite—they are ignoring or minimizing millions of other deaths because those deaths didn’t happen to be dramatic enough. A parent killed by a heart attack is just as lost as a parent who died in 9/11. A friend who died of brain cancer is just as gone as a friend who was killed in a terrorist attack. A child killed in a car accident is just as much a loss as a child killed by suicide bombers. If you really care about human suffering, I contend that you should care about all human suffering, not just the kind that makes the TV news.

Here is a list, from the CDC, of things that kill more Americans per month than terrorists have killed in the last three decades:

Heart disease: 50,900 per month

Cancer: 48,700 per month

Lung disease: 12,400 per month

Accidents: 10,800 per month

Stroke: 10,700 per month

Alzheimer’s: 7,000 per month

Diabetes: 6,300 per month

Influenza: 4,700 per month

Kidney failure: 3,900 per month

Terrorism deaths since 1985: 3,455
Yes, that’s right; influenza kills more Americans per month (on average; flu is seasonal, after all) than terrorism has killed in the last thirty years.
And for comparison, other violent deaths, not quite but almost as many per month as terrorism has killed in my entire life so far:
Suicide: 3,400 per month

Homicide: 1,300 per month

Now, with those figures in mind, I want you to ask yourself the following question: Would you be willing to give up basic, fundamental civil liberties in order to avoid any of these things?

Would you want the government to be able to arrest you and imprison you without trial for eating too many cheeseburgers, so as to reduce the risk of heart disease and stroke?

Would you want the government to monitor your phone calls and Internet traffic to make sure you don’t smoke, so as to avoid lung disease? Or to watch for signs of depression, to reduce the rate of suicide?

Would you want the government to be able to use targeted drone strikes, ordered directly by the President, pre-emptively against probable murderers (with a certain rate of collateral damage, of course), to reduce the rate of homicide?

I presume that the answer to all the above questions is “no”. Then now I have to ask you: Why are you willing to give up those same civil liberties to prevent a risk that is three hundred times smaller?

And then of course there’s the Iraq War, which killed 4,400 Americans and at least 100,000 civilians, and the Afghanistan War, which killed 3,400 allied soldiers and over 90,000 civilians.

In response to the horrific murder of 3,000 people, we sacrificed another 7,800 soldiers and killed another 190,000 innocent civilians. What exactly did that accomplish? What benefit did we get for such an enormous cost?

The people who sold us these deadly wars and draconian policies did so based on the threat that terrorism could somehow become vastly worse, involving the release of some unstoppable bioweapon or the detonation of a full-scale nuclear weapon, killing millions of people—but that has never happened, has never gotten close to happening, and would be thousands of times worse than the worst terrorist attacks that have ever actually happened.

If we’re worried about millions of people dying, it is far more likely that there would be a repeat of the 1918 influenza pandemic, or an accidental detonation of a nuclear weapon, or a flashpoint event with Russia or China triggering World War III; it’s probably more likely that there would be an asteroid impact large enough to kill a million people than there would be a terrorist attack large enough to do the same.

As it is, heart disease is already killing millions of people—about a million every two years—and we aren’t so panicked about that as to give up civil liberties. Elsewhere in the world, malnutrition kills over 3 million children per year, essentially all of it due to extreme poverty, which we could eliminate by spending between a quarter ($150 billion) and a half ($300 billion) of our current military budget ($600 billion); but we haven’t even done that even though it would require no loss of civil liberties at all.

Why is terrorism different? In short, the tribal paradigm.

There are in fact downsides to not being infinite identical psychopaths, and this is one of them. An infinite identical psychopath would simply maximize their own probability of survival; but finite diverse tribalists such as we underreact to some threats (such as heart disease) and overreact to others (such as terrorism). We’ll do almost anything to stop the latter—and almost nothing to stop the former.

Terrorists are perceived as a threat not just to our individual survival like heart disease or stroke, but a threat to our tribe from another tribe. This triggers a deep, instinctual sense of panic and hatred that makes us willing to ignore principles we would otherwise uphold and commit acts of violence we would otherwise find unimaginable.

Indeed, it’s precisely that instinct which motivates the terrorists in the first place. From their perspective, we are the other tribe that threatens their tribe, and they are therefore willing to stop at nothing until we are destroyed.

In a fundamental way, when we respond to terrorism in this way we do not defeat them—we become them.
If you ask people who support the PATRIOT ACT, it’s very clear that they don’t see themselves as imposing upon the civil liberties of Americans. Instead, they see themselves as protecting Americans (our tribe), and they think the impositions upon civil liberties will only harm those who don’t count as Americans (other tribes). This is a pretty bizarre notion if you think about it carefully—if you don’t need a warrant or probable cause to imprison people, then what stops you from imprisoning people who aren’t terrorists?—but people don’t think about it carefully. They act on emotion, on instinct.

The odds of terrorists actually destroying America by killing people are basically negligible. Even the most deadly terrorist attack in recorded history—9/11—killed fewer Americans than die every month from diabetes, or every week from heart disease. Even the most extreme attacks feared (which are extremely unlikely) wouldn’t be any worse than World War II, which of course we won.

But the odds of terrorists destroying America by making us give up the rights and freedoms that define us as a nation? That’s well underway.

Free trade, fair trade, or what?

JDN 2457271 EDT 11:34.

As I mentioned in an earlier post, almost all economists are opposed to protectionism. In a survey of 264 AEA economists, 87% opposed tariffs to protect US workers against foreign competition.

(By the way, 58% said they usually vote Democrat and only 23% said they usually vote Republican. Given that economists are overwhelmingly middle-age rich White males—only 12% of tenured faculty economists are women and the median income of economists is over $90,000—that’s saying something. Dare I suggest it’s saying that Democrat economic policy is usually better?)

There are a large number of published research papers showing large positive effects of free trade agreements, such as this paper, and this paper, and this paper, and this paper. It’s hard to find any good papers showing any significant negative effects. This is probably why the consensus is so strong; the empirical evidence is overwhelming.

Yet protectionism is very popular among the general public. The majority of both Democrat and Republican voters believe that free trade agreements have harmed the United States. For decades, protectionism has always been the politically popular answer.

To be fair, it’s actually possible to think that free trade harms the US but still support free trade; actually there are some economists who argue that free trade has harmed the US, but has benefited other countries like China and India so much more that it is worth it, making free trade an act of global altruism and good will (for the opposite view, here’s a pretty good article about how “free trade” in principle is often mercantilism in practice, and by no means altruistic). As Krugman talks about, there is some evidence that income inequality in the First World has been exacerbated by globalization—but it’s clearly not the primary reason for rising inequality.

What’s going on here? Are economists ignoring the negative impacts of free trade because it doesn’t fit their elegant mathematical models? Is the general public ignorant of how trade actually works? Does the way free trade works, or its interaction with human psychology, inherently obscure its benefits while emphasizing its harms?

Yes. All of the above.

One of the central mistakes of neoclassical economics is the tendency to over-aggregate. Instead of looking at the impact on individuals, it’s much easier to look at the impact on aggregated abstractions like trade flows and GDP. To some extent this is inevitable—there are simply too many people in the world to keep track of them all. But we need to be aware of what welose when we aggregate, and we need to test the robustness of our theories by applying different models of aggregation (such as comparing “how does this affect Americans” with “how does this affect the First World middle class”).

It is absolutely unambiguous that free trade increases trade flows and GDP, and for small countries these benefits can be mind-bogglingly huge. A key part of the amazing success story of economic development that is Korea is that they dramatically increased their openness to global trade.

The reason for this is absolutely fundamental to economics, and in grasping it in 1776 Adam Smith basically founded the field: Voluntary trade benefits both parties.

As most economists would put it today, comparative advantage leads to Pareto-improving gains from trade. Or as I’d tend to put it, more succinctly yet just as thoroughly based in modern game theory: Trade is nonzero-sum.

When you sell a product to someone, it is because the money they’re offering you is worth more to you than the product—and because the product is worth more to them than the money. You each lose something you value less and gain something you value more—so you are both better off.

This mutual benefit occurs whether you are individuals, corporations, or nations. It’s a fundamental principle of economics that underlies the operation of markets at every scale.

This is what I think most people don’t understand when they say they want to “stop sending jobs overseas”. If by that all you mean is ensuring that there aren’t incentives to offshore and outsource, that’s quite reasonable. Even some degree of incentive to keep businesses in the US might make sense, to avoid a race-to-the-bottom in global wages. But I get the sense that it is more than this, that people have a general notion that jobs are zero-sum and if we hire a million people in China that means a million people must lose their jobs in the US. This is not simply wrong, it is fundamentally wrong; it misses the entire point of economics. If there is one core principle that defines economics, I think it would be that the universe is nonzero-sum; gains for some can also be gains for others. There is not a fixed amount of stuff in the world that we distribute; we can make more stuff. Handled properly, a trade that results in a million people hired in China can mean an extra million people hired in the US.

Once you introduce a competitive market, things get more complicated, because there aren’t just winners—there are also losers. When you have competitors, someone can buy from them instead of you, and the two of them benefit, but you are harmed. By the standard methods of calculating benefits and harms (which admittedly leave much to be desired), we can show quite clearly that in general, on average, the benefits outweigh the harms.

But of course we don’t live “in general, on average”. Despite the overwhelming, unambiguous benefit to the economy as a whole, there is some evidence that free trade can produce a good deal of harm to specific individuals.

Suppose you live in the US and your job is to assemble iPads. You’re good at it, you like it, it pays pretty well. But now Apple says that they want to “reduce labor costs” (they are in fact doing nothing of the sort; to really reduce labor costs in a deep economic sense you’d have to make work easier, more productive, or more fun—the wage and the cost are fundamentally different things), so they outsource production to Foxconn in China, who pay wages 1/30 of what you were being paid.

The net result of this change to the economy as a whole is almost certainly positive—the price of iPads goes down, we all get to have iPads. (There’s a meme going around claiming that the price of an iPad would be almost $15,000 if it were made in the US; no, it would cost about $1000 even if our productivity were no higher and Apple could keep their current profit margin intact, both of which are clearly overestimates. But since it’s currently selling for about $500, that’s still a big difference.) Apple makes more profits, which is why they did it—and we do have to count that in our GDP. Most importantly, workers in China get employed in safe, high-skill jobs instead of working in coal mines, subsistence farming, or turning to drugs and prostitution. More stuff, more profits, better jobs for some of the world’s poorest workers. These are all good things, and overall they outweigh the harm of you losing your job.

Well, from a global perspective, anyway. I doubt they outweigh the harm from your perspective. You still lost a good job; you’re now unemployed, and may have skills so specific that they can’t be transferred to anything else. You’ll need to retrain, which means going back to school or else finding one of those rare far-sighted companies that actually trains their workers. Since the social welfare system in the US is such a quagmire of nonsensical programs, you may be ineligible for support, or eligible in theory and unable to actually get it in practice. (Recently I got a notice from Medicaid that I need to prove again that my income is sufficiently low. Apparently it’s because I got hired at a temporary web development gig, which paid me a whopping $700 over a few weeks—why, that’s almost the per-capita GDP of Ghana, so clearly I am a high-roller who doesn’t need help affording health insurance. I wonder how much they spend sending out these notices.)

If we had a basic income—I know I harp on this a lot, but seriously, it solves almost every economic problem you can think of—losing your job wouldn’t make you feel so desperate, and owning a share in GDP would mean that the rising tide actually would lift all boats. This might make free trade more popular.

But even with ideal policies (which we certainly do not have), the fact remains that human beings are loss-averse. We care more about losses than we do about gains. The pain you feel from losing $100 is about the same as the joy you feel from gaining $200. The pain you feel from losing your job is about twice as intense as the joy you feel from finding a new one.

Because of loss aversion, the constant churn of innovation and change, the “creative destruction” that Schumpeter considered the defining advantage of capitalism—well, it hurts. The constant change and uncertainty is painful, and we want to run away from it.

But the truth is, we can’t. There’s no way to stop the change in the global economy, and most of our attempts to insulate ourselves from it only end up hurting us more. This, I think, is the fundamental reason why protectionism is popular among the general public but not economists: The general public sees protectionism as a way of holding onto the past, while economists recognize that it is simply a way of damaging the future. That constant churning of people gaining and losing jobs isn’t a bug, it’s a feature—it’s the reason that capitalism is so efficient in the first place.

There are a few ways we can reduce the pain of this churning, but we need to focus on that—reducing the pain—rather than trying to stop the churning itself. We should provide social welfare programs that allow people to survive while they are unemployed. We should use active labor market policies to train new workers and match them with good jobs. We may even want to provide some sort of subsidy or incentive to companies that don’t outsource—a small one, to make sure they don’t do so needlessly, but not a large one, so they’ll still do it when it’s actually necessary.

But the one thing we must not do is stop creating jobs overseas. And yes, that is what we are doing, creating jobs. We are not sending jobs that already exist, we are creating new ones. In the short run we also destroy some jobs here, but if we do it right we can replace them—and usually we do okay.

If we stop creating jobs in India and China and around the world, millions of people will starve.

Yes, it is as stark as that. Millions of lives depend upon continued open trade. We in the United States are a manufacturing, technological and agricultural superpower—we could wall ourselves off from the world and only see a few percentage points shaved off of GDP. But a country like Nicaragua or Ghana or Vietnam doesn’t have that option; if they cut off trade, people start dying.

This is actually the main reason why our trade agreements are often so unfair; we are in by far the stronger bargaining position, so we can make them cut their tariffs on textiles even as we maintain our subsidies on agriculture. We are Mr. Bumble dishing out gruel and they are Oliver Twist begging for another bite.

We can’t afford to stop free trade. We can’t even afford to significantly slow it down. A global economy is the best hope we have for global peace and global prosperity.

That is not to say that we should leave trade completely unregulated; trade policy can and should be used to enforce human rights standards. That enormous asymmetry in bargaining power doesn’t have to be used to maximize profits; it can be used to advance human rights.

This is not as simple as saying we should never trade with nations that have bad human rights records, by the way. First of all that would require we cut off Saudi Arabia and China, which is totally unrealistic and would impoverish millions of people; second it doesn’t actually solve the problem. Instead we should use sanctions, tariffs, and trade agreements to provide incentives to improve human rights, rewarding governments that do and punishing governments that don’t. We could have a sliding tariff that decreases every time you show improvement in human rights standards. Think of it like behavioral reinforcement; reward good behavior and you’ll get more of it.

We do need to have sweatshops—but as Krugman has come around to realizing, we can make sweatshops safer. We can put pressure on other countries to treat their workers better, pay them more—and actually make the global economy more efficient, because right now their wages are held down below the efficient level by the power that corporations wield over them. We should not demand that they pay the same they would here in the First World—that’s totally unrealistic, given the difference in productivity—but we should demand that they pay what their workers actually deserve.

Similar incentives should apply to individual corporations, which these days are as powerful as some governments. For example, as part of a zero-tolerance program against forced labor, any company caught using or outsourcing to forced labor should have its profits garnished for damages and the executives who made the decision imprisoned. Sometimes #Scandinaviaisnotbetter; IKEA was involved in such outsourcing during the Cold War, and it is currently being litigated just how much they knew and what they could have done about it. If they knew and did nothing, some IKEA executive should be going to prison. If that seems extreme, let me remind you what they did: They used slaves.

My standard for penalizing human rights violations, whether by corporations or governments, is basically like this: Follow the decision-making up the chain of command, stopping only when the next-higher executive can clearly show to the preponderance of evidence that they were kept out of the loop. If no executive can provide sufficient evidence, the highest-ranking executive at the time the crime was committed will be held responsible. If you don’t want to be held responsible for crimes committed by people who work for you, it’s your responsibility to bring them to justice. Negligence in oversight will not be exonerating because you didn’t know; it will be incriminating because you should have. When your bank is caught laundering money for terrorists and drug lords, it isn’t enough to have your chief of compliance resign; he should be imprisoned—and if his superiors knew about it, so should they.

In fact maybe the focus should be on corporations, because we have the legal authority to do that. When dealing with other countries, there are United Nations rules and simply the de facto power of large trade flows and national standing armies. With Saudi Arabia or China, there’s a very real chance that they’ll simply tell us where we can shove it; but if we get that same kind of response from HSBC or Goldman Sachs (which, actually, we did), we can start taking out handcuffs (that, we did not do—but I think we should have).

We can also use consumer pressure to change the behavior of corporations, such as Fair Trade. There’s some debate about just how effective these things are, but the comparison that is often made between Fair Trade and tariffs is ridiculous; this is a change in consumer behavior, not a change in government policy. There is absolutely no loss of freedom. Choosing not to buy something does not constitute coercion against someone else. Maybe there are more efficient ways to spend money (like donating it directly to the best global development charities), but if you start going down that road you quickly turn into Peter Singer and start saying that wearing nicer shoes means you’re committing murder. By all means, let’s empirically study different methods of fighting poverty and focus on the ones that work best; but there’s a perverse smugness to criticisms of Fair Trade that says to me this isn’t actually about that at all. Instead, I think most people who criticize Fair Trade don’t support the idea of altruism at all—they’re far-right Randian libertarians who honestly believe that selfishness is the highest form of human morality. (It is in fact the second-lowest, according to Kohlberg.) Maybe it will turn out that Fair Trade is actually ineffective at fighting poverty, but it’s clear that an unregulated free market isn’t good at that either. Those aren’t the only options, and the best way to find out which methods work is to give them a try. Consumer pressure clearly can work in some cases, and it’s a low-cost zero-regulation solution. They say the road to Hell is paved with good intentions—but would you rather we have bad intentions instead?

By these two methods we could send a clear message to multinational corporations that if they want to do business in the US—and trust me, they do—they have to meet certain standards of human rights. This in turn will make those corporations put pressure on their suppliers, all the way down the supply chain, to uphold the standards lest they lose their contracts. With some companies upholding labor standards in Third World countries, others will be forced to, as workers refuse to work for companies that don’t. This could make life better for many millions of people.

But this whole plan only works on one condition: We need to have trade.
