Here is a link to my piece in today’s issue of Time.com; and here’s the executive summary:

Deep inside a West Texas mountain, engineers are building a clock designed to click for 10,000 years. Amazon.com’s Jeff Bezos has sunk $43 million into this project and that’s just a start. What’s the purpose? “To foster long-term thinking and responsibility in the framework of the next 10,000 years”, say the organizers.

Now thinking and responsibility are two different things, but it’s hard to see how this project is likely to encourage either. Re thinking: The question of what we owe to future generations is subtle and difficult and requires close attention to difficult arguments; it’s hard to see how a ticking clock will do to foster that kind of effort. And as for responsiblity — if responsibility means making a better life for our distant descendants, then Bezos’s $43 million would almost surely be better spent on lobbying for lower capital taxes. Whether the goal is thinking or responsibility, a giant clock seems like a giant waste of time.

Charting the Tax Plans

Ezra Klein, quoted with approval by Paul Krugman, offers this chart of how the Obama and Romney tax proposals will change rates for taxpayers in various quintiles:

What we’re supposed to infer, according to Krugman, is that

we have an election in which one candidate is proposing a redistribution from the top … downward, mainly to lower-income workers, while the other is proposing a large redistribution from the poor and the middle class to the top.

But no such thing is remotely true. What we actually have is an election in which both candidates are proposing massive redistributions from the top downward, one slightly less so than the other. You’d never know this from looking at Klein’s chart because it illustrates changes in rates, whereas what actually matters is the rates themselves. It makes no sense to ask whether any particular group ought to be paying more or less without reference to how much they’re already paying.

Indeed, this is a classic example of what I once called the “Grandfather Fallacy” — by focusing on changes instead of absolutes, Klein’s chart conceals any existing inequities and hence treats them as “grandfathered in”.

Fortunately, Greg Mankiw has provided the numbers that allow us to make the requisite correction. Here, according to Mankiw, are the current tax burdens on various income groups (counting transfers as negative taxes, as of course one should):

Bottom quintile: -301 percent
Second quintile: -42 percent
Middle quintile: -5 percent
Fourth quintile: 10 percent
Highest quintile: 22 percent

Top one percent: 28 percent

That “-301 percent” means, for example, that a typical family in the bottom quintile receives $3.01 in net transfers for every $1 that it earns.

By adding these numbers to the numbers in Klein’s graph, we can construct a picture that actually depicts something interesting, namely the projected tax burdens for each group. It looks like this (the vertical axis represents percentage of income):

Note, for example, that, contrary to the impression you might have gotten from Klein’s and Krugman’s posts, both plans place the highest percentage burden on the top 1%, and both plans place a negative burden on the middle quintile — though Obama’s does both of these things to an ever-so-slightly greater extent than Romney’s does. There’s room for disagreement about which plan is fairer, but no room, I think, for disagreement about which chart is relevant.

If you study economics, or statistics, or chemistry, or mathematical biology, or thermodynamics, you’re sure to encounter the notion of a Markov chain — a random process whose future depends probabilistically on the present, but not on the past. If you travel through New York City, randomly turning left or right at each corner, then you’re following a Markov process, because the probability that you’ll end up at Carnegie Hall depends on where you are now, not on how you got there.

But even if you work with Markov processes every day, you’re probably unaware of their origins in a dispute about free will, Christianity, and the Law of Large Numbers.

Disposable Thumbs

The average economist would sacrifice 1.02 years of life to avoid losing a thumb, or .77 years of life to get a paper published in the American Economic Review. An AER publication, then, is worth about 3/4 of a thumb.

We learn this from a study by three economists who sent out 1300 questionnaires, all to economists who had recently published in one of six major journals. They received 85 responses. Of these, 7 were discarded because they claimed to value their thumbs more than their entire hands, or their hands more than their entire arms, and another four were discarded because they indicated they were willing to sacrifice life-years for the privilege of losing a body part. The remaining 74 respondents valued their body parts as follows:

Here (as reported in the May 14 issue of The New Yorker) are the requirements listed by a female graduate student seeking a mate on the Chinese equivalent of match.com:

  • Never married
  • Masters degree or more
  • Not from Wuhan
  • No rural I.D. card
  • No only children
  • No smokers
  • No alcoholics
  • No gamblers
  • Taller than one hundred and seventy-two centimeters
  • More than a year of dating before marriage
  • Sporty
  • Parents who are still together
  • Annual salary over fifty thousand yuan
  • Between twenty-six and thirty-two years of age

(As is often the case with school children, the exact rules tend to get negotiated in real time as the puzzle is being solved.) Some examples are:

A Naive Question

Can someone help me understand this?

1) The Constitution, as amended, gives the federal government the right to levy taxes uniformly across the states, and also to tax income.

2) The federal gasoline tax is neither levied uniformly across states nor is it a tax on income. Thus it must be justified under something other than the explicit taxing powers set forth in the Constitution.

3) I’ve always sort of presumed that the missing justification is provided by the Commerce Clause.

4) In other words, the right to levy a gasoline tax seems to be dependent on the Commerce Clause.

5) By the same reasoning, the right to levy a tax on not-having-health-insurance would seem to be dependent on the Commerce Clause.

6) But John Roberts says explicitly that the Commerce Clause can not be used to justify a tax on not-having-health-insurance.

7) How, then, can a tax on not-having-health insurance possibly be constitutional? It’s not levied uniformly across states, it’s not a tax on income, and we have the Chief Justice’s word that it can’t be justified by the Commerce Clause. Whence, then, the constitutional authority to levy such a tax?

So the individual mandate is Constitutional because it’s a tax.

I wonder if the Chief Justice forgot that all tax legislation must originate in the House of Representatives. There’s that pesky Constitution again.

Hat tip to Jim Kahn for this.

Last week, I challenged readers to reconcile two apparently contradictory statements, both of which are frequently made in economics textbooks:

  • To minimize distortions, all goods should be taxed equally.
  • To minimize distortions, inelastically demanded goods should be taxed more heavily. (This is sometimes called the Ramsey rule, after Frank Ramsey, who plays a major role in the final chapter of The Big Questions).

I’ll give you the answer in a minute. The executive summary is that a) “Inelastically demanded goods should be taxed more heavily” is true only in very special circumstances; in general a much more complicated formula is needed, b) When all goods can be taxed, that complicated formula does in fact tell you to tax them all equally, and c) a lot of textbooks give incredibly misleading accounts of all this.

The more detailed answer follows; if you prefer a more mathematical account, click here. To keep things manageable, I’ve assumed all supply curves are perfectly elastic.

Immigration Followup

. 150 Comments

I’m a little frazzled this week, so I haven’t caught up with all the comments on Monday’s
post on immigration, but I know there’s been some discussion about the actual costs and benefits of admitting unskilled immigrants. I thought I’d supply some numbers that might inform that discussion; all of this is lifted from Chapter 20 of The Big Questions.

When an unskilled Mexican immigrant arrives in the United States, his wages typically rise from about $2 a hour to $9 an hour — call it a $7 an hour gain. He also bids down the wages of American workers by (and this is a high-end estimate from the labor economics literature) about $.00000003 per hour; multiply that by a hundred million American workers and you’ve got a collective $3 an hour loss.

Now there seems to be something like a consensus that it’s okay for US policies to benefit US citizens at the expense of Mexicans, but there also seems to be something like a consensus that there’s a limit to that; we would not want, for example, to allow Americans to hunt Mexicans for sport. So when we consider turning someone away at the border, one good question is: Are we willing to do $7 worth of harm to a Mexican in order to confer $3 worth of benefits on American workers?

Note that the potential Mexican immigrant is typically much poorer than those American workers, and that it’s not uncommonly argued that we should care more about the poor than about the rich. If you weight that $7 loss to the Mexican and that $3 gain to the Americans accordingly (i.e. assuming logarithmic utility, which is a quite conservative assumption — that is, one that biases the result in the anti-immigration direction), you discover exclusion hurts the Mexican about five times as much as it helps the Americans.

So, at least if you buy into that way of thinking (which pervades a lot of the policy literature) then exclusion is justified only if you “count” a Mexican as less than one-fifth of an American. That’s a pretty extreme position. It’s not as extreme as hunting Mexicans for sport, but it’s still pretty extreme.

And Everyone Who Supports Vaccinations is Motivated by a Desire to Stab People….

In an apparent case of libertarianism run amok, two cognitive scientists and one economist have declared (in effect) that proponents of income redistribution are always and everywhere motivated by exactly the same psychopathic impulses that lead people to scratch other people’s cars, break streetlamps, and engage in other forms of senseless destruction.

That’s not a conclusion; it’s their starting assumption. Then they do an experiment in which some subjects choose to engage in a mild form of income redistribution — and conclude that psychopathic behavior is frighteningly widespread.

Now I too am generally skeptical of the impulse to redistribute other people’s income, but even I concede that redistribution is rarely entirely senseless and pretty much never entirely destructive. In particular, the experimenters consider a case where money has just been redistributed and subjects are given the opportunity to (partly or fully) reverse that redistribution. Those who exercise that opportunity are labeled “destructive”. So apparently, in order to avoid the “destructive” label, you must passively accept any arbitrary redistributions imposed by authority figures without ever feeling any impulse to redistribute in the opposite direction.

In the experiment, each subject is initially awarded 1000 tokens. The paper is so poorly written that it’s hard to be sure, but I think these tokens are ultimately exchangeable for money; it’s mentioned that the average subject earns the equivalent of nine British pounds. One subject is then given the opportunity to destroy some of the other subject’s tokens, thereby returning some funds to the experimenters or to the taxpayers who are funding this experiment.

Rather shockingly (to me) only about 15.5% of the subjects exercised this option; given the presumption of public funding, I’d have hoped for a higher number. The experimenters, however, want to conclude that these 15.5% are the sorts who are likely to key your car.

This stuff is infuriatingly stupid. Even more distressingly, Robin Hanson, who is much much much too smart for this, seems to have fallen for it.

Thanks to an election-year conversion by the President of the United States, 800,000 young people born outside the country will now be spared the threat of deportation. That’s a good thing. But let’s not lose sight of the fact that the biggest victims of American immigration policy are not the ones we deport; they’re the ones who never got to come here in the first place.

The President defends his new policy as humane. Put aside the question of where his humanity has been for the past three and a half years and ask yourself what’s so humane about protecting the children of relatively rich “illegals” (that is, the ones who have had the opportunity to earn American wages) while we continue to bar the door to their desperately impoverished cousins.

Regarding the beneficiaries of this new policy, the President says that

These are young people who study in our schools, they play in our neighborhoods, they’re friends with our kids, they pledge allegiance to our flag …

Why is any of this relevant? When did visibility become a criterion for moral status?

This is indeed a time to celebrate and I don’t want to diminish that. But I do have two questions for the President:

Do any of you guys know anything about economics? Because I have a question I can’t answer and I’m hoping you can help me.

In many real estate markets (including the one where I’m currently shopping), the agent’s commission is equal to a fixed percentage of the sale price. (Typically it’s 6%, though this is split evenly between the buyer’s and seller’s agents, each of whom gives a cut to their respective agencies, so either agent’s take-home is more on the order of 2%).

This means that if you sell a million-dollar house, you earn TEN TIMES the commission of your identical twin who sold a hundred-thousand-dollar house, though I doubt very much that you did ten times the work or bore ten times the expense.

Now, plenty of hundred-thousand-dollar houses are being sold, which means that plenty of agents are settling for the relatively dinky commissions. Question: Why are those agents not attempting to steal some of the high-end business by offering to accept a smaller percentage? After all, 1% of a million is still a lot more than 2% of a hundred thousand.

You might say that the agencies collude to restrain them — but what stops a rogue agency from busting the cartel?

All too many times in my life, I’ve noticed some apparently anomalous behavior which I’ve challenged myself and/or others to explain with the tools of game theory, axiomatic bargaining theory, and the theory of markets — only to discover that the true explanation is “It’s required by law”. (Of course one can always step a little further back and try using economics to explain the advent of the law.) But I don’t think that’s the case here. (I’m prepared to be wrong about this, though.)

Okay. Are we ready?

I am pretty well convinced that 16 bags suffice, as argued by Mike H, Jeffrey, Brian, and Jacopo, and generalized by Categories+Sheaves.

The explanation I liked best was Jeffrey’s. Let me try to illustrate it. (Warning: There’s no way, I think, to make this instantly clear. It will take a little work to understand it. Only you can assess the opportunity cost of your own time!)

The gray rectangle is the room you’re in.

The blue dot is you. The red dot is the shooter.

With mirrors on all the walls, you’ll perceive yourself as standing in an infinite grid. The graph shows 16 of the grid rectangles, but the pattern continues forever in every direction.

You’re standing at some point (a,b). The shooter is at some point (p,q). You’ll see copies of that shooter at every point with coordinates (2m ± p, 2n ± q) where m and n range over all integers. Sixteen of those infinitely many points are shown in the picture.

Two of the main lessons that our undergraduates typically take away from their introductory classes are these:

  • To minimize distortions, all goods should be taxed at the same rate.
  • To minimize distortions, inelastically demanded goods should be taxed most heavily.

What is the correct response to this pair of apparently contradictory lessons?

hhwThe letter to the editor is a literary genre unique unto itself. Unlike the editorial or the op-ed, the letter typically allows its author only a couple of short paragraphs to make a single compelling point. A good blog post might ramble from one loosely connected idea to another, but a good letter proceeds directly to its target.

Don Boudreaux is, beyond any doubt, the modern master — no, the all-time master — of this underrated branch of literature. When a radio station interviews a Galveston resident who’s just topped off her gas tank in anticipation of Hurricane Ike — and who is furious to learn that gas prices have jumped 50 cents a gallon overnight even though “Ike hadn’t hit yet” — a blogger (or an Armchair Economist) might respond with a long-winded explanation of why it’s a good thing that supply, demand, and therefore prices respond quickly to a change in expectations. Boudreaux, instead, skips right to the heart of the matter:

Your reporter should have immediatedly asked this woman: “Well, why were you topping off your tank? Ike hadn’t hit yet.”

notredameA consortium of Catholic institutions, including the University of Notre Dame, is suing to overturn the Obama administration’s contraception mandate. I hope they lose. I think.

The birth control mandate strikes me as a very hard policy to defend, though I’ve done my part to put together the best possible arguments in its favor. For the record, I do think there’s a quite reasonable case to be made for some insurance mandates — primarily with regards to pre-existing conditions and catastrophic illnesses. (There’s also a very good case against those mandates, so don’t take this as an endorsement!). Those mandates at least address plausible market failures. A contraception mandate pretty clearly fails that test (though see the discussion at the linked post for some reasoned argument to the contrary).

So I believe the mandate is bad policy, both in its specifics and in its general presumption in favor of government power. If this isn’t unconstitutional, we need a better constitution. But that’s not the basis of Notre Dame’s lawsuit. Notre Dame’s position, as I understand it, is that Catholic institutions (as opposed to, say, General Electric) should be exempt from the mandate because religious objections (as opposed to, say, financial objections) have some kind of special exalted status. That strikes this non-lawyer as straying perilously close to a law respecting the establishment of religion. And if that’s not unconstitutional, then we really need a better constitution.

This has been making the rounds lately; I’m not sure where it first came from.

You’re in a rectangular room. Elsewhere in the room is a man with a gun, who shoots a bullet in a random direction. The bullet careens around the room, bouncing off walls, until it hits either you or one of the various punching bags you’ve placed around the room for purposes of absorbing the bullet. The punching bags must be positioned before you know the random direction of the bullet (though you do know both your own location and the bad guy’s location, neither of which you can change). How many punching bags do you need to guarantee your survival?

This being a math problem, you should treat the room as two dimensional, and yourself, the bullet and the punching bags as points.

Though YouTube says this is from a 1991 Collins concert in California, she performed a nearly identical rendition at Wolf Trap in 2000. The Live at Wolf Trap CD is well worth its exorbitant price; every track is stunning.

Sixteen years ago, Slate Magazine was launched, with Paul Krugman and me as the alternating economics columnists. At the time, Paul was fond of observing (with considerable dismay) that most of the time, highly educated and intelligent non-economists appear to be completely incapable of distinguishing between compelling arguments and utter nonsense in the field of economics. His essay on “Pop Internationalism” is a brilliant series of riffs on this theme — a guided tour of sheer balderdash that gets a respectable hearing even though no economist could possibly take it seriously. “Pop Internationalism” (the lead essay in the book of the same name) is high on my recommended reading list.

The lesson I took from this observation was that we (Krugman, I, and economic commentators in general) had a responsibility to explain not just what economists believe, but why we believe it — to help readers understand that there’s a rigorous underlying logic to the discipline, and that there are good reasons for insisting that people adhere to that logic. Nowadays, when he’s at his most obstreperous, I sometimes suspect Krugman of having drawn a very different lesson — that because nobody understands the real logic of economics, we can get away with saying any damned thing we want to. It’s a frustrating thing to watch, because when he’s good, he’s very very good. But when he is bad he is horrid. I won’t list examples here, but you can find quite a few by browsing my Paul Krugman archive.

obamaThe President of the United States thinks that gay marriage should be legal. So do I. But I have two coments:

First, I am dismayed by the notion that anyone’s vote might be swayed by this issue, in either direction.

As I said earlier in the week, I do understand why this is an issue of major importance in some people’s lives. But the number of people affected, and the magnitude of the effects, are still meager compared to the effects of, say, trade or immigration policy. What ever happened to perspective?

Of course, Bryan Caplan will tell you that voters are systematically irrational in any event, so it might be just as well that they’re basing their votes on things that don’t matter very much, as opposed to basing their votes on things that really matter and getting them wrong. But it’s still disheartening to think about.

Second, I am dismayed by the President’s suggestion that he came to this viewpoint through observation of “incredibly committed monogamous” same-sex relationships among his staffers — suggesting (though not outright asserting) that monogamy ought to be somehow relevant to the legal status of one’s marriage. And here I’d thought the whole point of this gay marriage thing was that the way people have sex is not properly a concern of the legal authorities. If he’s continuing to deny this principle, then the President remains philosophically on the same side of this divide as Family Research Council.

The new revised edition of The Armchair Economist is now on sale in paperback and electronic versions. Last week’s glitch (where the electronic versions were of the wrong edition) is fixed.

For almost twenty years, Armchair has been widely recognized among economists as the book to give your mother when she wants to understand what you think about all day. In this new version, fully updated for the 21st century, I’ve completely rewritten several chapters to make them even clearer, livelier and more contemporary.

I (and you if you buy the book) am deeply indebted to Lisa Talpey who read every chapter multiple times, insisting that I keep rewriting until everything met her meticulous standards of clarity. Chapters I’d thought were pretty good are vastly improved thanks to Lisa; these include:

  • Why Popcorn Costs More at the Movies (and Why the Obvious Answer is Wrong)
  • Was Einstein Credible? (The Economics of Scientific Method)
  • The Indifference Principle (Who Cares if the Air is Clean?)

    • and

  • Why Taxes Are Bad (The Logic of Efficiency)

Others are almost completely rewritten to focus on issues that are in the news today; these include

  • The Mythology of Deficits

    • and

  • Unsound and Furious: Spurious Wisdom from the Media

By way of general housecleaning, I’ve excised all references to cassette tapes, Polaroid film, and Walter Mondale.

You can read the preface here. You can buy the book here. Here are direct links to the updated Kindle and Nook editions. (These editions are advertised as “published November 2007”, but don’t panic; that’s just the lingering shadow of last week’s glitch. They’re actually the brand-new 2012 edition.)

Dan Seligman at Fortune called the first edition of The Armchair Economist “enormous fun from its opening page”; Alfred Malabre of the Wall Street Journal called it “the most enjoyable and sensible book by an economist about economics that I’ve read in donkey’s years”; Milton Friedman called it “an ingenious and highly original presentation of some central principles of economics for the proverbial Everyman”; George Gilder called it “a crisp, lively, pungent display of the economist’s art”. This second edition is, I believe, all that and more.

The Armchair Economist is indeed the perfect gift for your mother, or for your father, or for the new college grad in your life, or even for yourself. Enjoy it, and come join the discussion right here.

As long as we have anything like traditional marriage, I believe that restricting it to heterosexual couples is an exceptionally bad and stupid policy, laced with unnecessary cruelty. It is not, however, an issue that is likely ever to affect my vote, because so much else dwarfs its importance. Legalizing gay marriage would make life substantially better for a few million people of the wealthiest people in the world (i.e. Americans) and is therefore a good thing, but if I’m going to pick my battles, I’ll cast my lot with, say, the tens or hundreds of millions of Third Worlders who are relegated to dire poverty by American trade and immigration restrictions. I’ll take the homophobic free trader over the protectionist crusader for sexual equality every single time.

The all-new revised edition of The Armchair Economist is now available in a Kindle edition (as well as paperback) here.

As of this writing, the Amazon page still says you are buying the 2007 version, but that’s wrong. The version you’ll get is the new 2012 version.

Barnes and Noble still has the 1993 version for the Nook. This will be fixed in a day or two.

devilIn the comments section of Bob Murphy’s blog, I was asked (in effect) why I insist on the objective reality of the natural numbers (that is, the counting numbers 0,1,2,3…) but not of, say, the real numbers (that is, the numbers we use to represent lengths — and that are themselves represented by possibly infinite decimal expansions).

There seem to be two kinds of people in the world: Those with enough techncal backgroud that they already know the answer, and those with less technical background, who have no hope — at least without a lot of work — of grasping the answer. I’m going to attempt to bridge that gap here. That means I’m going to throw a certain amount of precision to the winds, in hopes of being comprehensible to a wider audience.

Edited to Add: These problems are fixed now! The electronic versions are correct. They are still advertised as November 2007 editions, but they are in fact the May 2012 edition. You can now trust the links at http://www.TheBigQuestions.com/buy .

hangToday (May 1) was the official publication date for the all-new revised edition of The Armchair Economist. (Read the preface here.) Unfortunately, we had a major communication screw-up and purchasers of the electronic editions (Kindle, Nook, etc.) are still receiving the 1993 edition (which is labeled the “2007 edition” because that’s when it was converted to an e-book). This will be fixed in a day or so. I’ll post to let you know when it’s safe to buy.

Meanwhile, if you’ve recently purchased an electronic Armchair Economist, I encourage you to return it, wait just a day or two till you see the announcement that all systems are go, and then buy it all over again.

I cannot begin to tell you how sorry I am about this. There is at least one very particular head I’d like to see roll.

Thanks for bearing with the glitch, and watch this space for the big announcement that all systems are go.
