Your lying heart

As a graduate student, I attended some courses on the art and science of psychotherapy. During one of these lectures, our teacher imparted a morsel of clinical wisdom. This is what he told us: "You will from time to time meet a patient who shares a disturbing tale of multiple mistakes in his previous treatment. He has been seen by several clinicians, and all failed him. The patient can lucidly describe how his therapists misunderstood him, but he has quickly perceived that you are different. You share the same feeling, are convinced that you understand him, and will be able to help." At this point my teacher raised his voice as he said, "Do not even think of taking on this patient! Throw him out of the office! He is most likely a psychopath and you will not be able to help him."

What words can do justice

From the National Geographic on the Rhino Wars
Game scouts found this black rhino bull wandering Zimbabwe's Savé Valley Conservancy after poachers shot it several times and hacked off both its horns. Veterinarians had to euthanize the animal because its shattered shoulder couldn't support its weight.
Adam Omizek at Modeled Behavior recently blogged
I have argued that consumer pressure for better treatment of animals in agriculture is a good thing, but that pressuring for better treatment of workers might lead to worse outcomes.
He is writing about animals in agriculture, but what he says applies in general. We are the most powerful species ever to roam the planet, and it is amazing how badly we behave.

Moneyball: this is not a review

I recently watched Moneyball.

One of the most moving scenes in the movie is the one where you watch Billy Beane begins to assemble a team from players who have been overlooked by other teams. You can see how much it matters to them when he asks him to play for him.

What does this imply for my post about Meritocracy?

Doesn't it show that free markets reward talent? Doesn't it show that free markets reward those who can see the value in outsiders and put them to work? Doesn't it show that free markets are meritocracies, and isn't that a good thing?
My answers to these questions would be: yes, yes, and a qualified no.

Markets are wonderful. We should try to find the right person for the job, and we should reward people for doing their jobs well. The bourgeois virtues are very real.

My post on Merit was not an argument against using markets.

Since the 1980s, the best cricket players in India have been growing ever richer. However, that they earn a hundred times what their predecessors used to earn doesn't mean that they are a hundred times as good at the game. They have grown richer mainly because Indians now watch television. In some other countries, the benefits have gone to Football players, while in other countries, Basketball players have gained. These beneficiaries may be great athletes, and they "deserve" their incomes in the sense that this is what others willingly pay them in the marketplace. They are like landlords who have seen the value of their properties explode because someone else built a highway or a railway station nearby.

Hockey is supposedly India's "National Game" and the Indian Hockey team is the most successful team in Olympic History. However, they earn a fraction of what Cricketers earn. There are excellent historical and infrastructural reasons for this. However, to say that Cricket is a better team than Hockey, or that Cricketers are better athletes than Hockey players would be silly. That is my first point: however hard we work, and these athletes work very hard indeed, we underestimate the contribution of luck to our wealth.

Merit, in the sense in which we use it here, is also a morally neutral term. In the movie, Billy Beane recruits players whom others won't touch because they are arrogant, or because they take drugs and frequent strip clubs. As he puts it, all he cares about is whether they are cheap and can "get on base". Personally, I have no problems with people who use drugs or go to strip clubs. The point I am trying to make is that if Billy Beane is rewarding merit, both merit and reward are of the narrowest kind: he reognizes technical competence, and rewards it with money.

Billy Beane was doing The Market's work, and that is good. However, The Market giveth, and the Market taketh away.

We underestimate the importance of the environment: we see those who thrive and see that they are intelligent, hard-working, and conscientous, and they often are! We then assume that they would have thrived in all possible worlds. We don't notice that many of those who are left behind are also were hard-working and dilgent. We also forget that we often seem most virtuous (energetic, optimistic, generous) when things are going our way.

This has moral consequences: instead of being grateful, the successful evolve a fine sense of entitlement, while the defeated blame themselves. This is not only a human tragedy, but a mistaken understanding of how the world works.

Note: Prices are a signal. When wages rise, workers should move into that industry. However, the number of spots on the Indian Cricket team is limited to 11 (plus extras). What we see are more players trying to get in, and a few who do make it and earn huge sums. Most of us do not work in such industries. When wages rise, people enter our industry.
However, this does not mitigate the tragedy of declining industries: I doubt former steel plant engineers are any less intelligent or hardworking that programmers, but they cannot easily start over again.

I don't intend to write any more posts about tax for a while. However, Tim Harford makes an interesting point in this article
But few people seem to have recognised that if the entrepreneurial activity in question is avoiding tax through artificial loopholes, it might be a very good idea to generate some uncertainty and give pause for thought.
I don't agree, but an interesting comment nevertheless.

Taxes II

I recently read this article in which Samuel Brittan argues for a tax on land, and quotes Winston Churchill
Roads are made, streets are made, services are improved, electric light turns night into day, water is brought from reservoirs a hundred miles off in the mountains - and all the while the landlord sits still. Every one of those improvements is effected by the labour and cost of other people and the taxpayers. To not one of those improvements does the land monopolist, as a land monopolist, contribute, and yet by every one of them the value of his land is enhanced. He renders no service to the community, he contributes nothing to the general welfare, he contributes nothing to the process from which his own enrichment is derived.
I am no expert on Georgism, but I am intrigued.

Bryan Caplan, however, doesn't like it.
There's just one problem: While the Georgist tax has no effect on the incentive to pump discovered oil, it has a devastating effect on the incentive to discover oil in the first place. Suppose you could find a $1M well by spending $900k on exploration. With a 99% Georgist tax, your expected profits are negative $890k.
I am nor persuaded by Bryan's argument. The company will look at the total profits which it can make by investing in finding and developing the oil field.

First, it will pay a higher tax on the land it owns, but since it will no longer be taxed on the profits it makes from extracting, refining, and distributing the oil which it finds, it is not clear that its total profits will be any less.

Second, it is not the case that the company's profits from oil exploration are higher in the absence of the land tax: what would be paid as land tax would instead be paid to the landlord. The effect of the Georgist tax is to transfer rent from the current owner of the land to the State. Whether this is a good thing or not is debatable, but the tax is not paid by the company which finds the oil nor the one which develops it, and will not affect their incentives. Note that this is Ricardian rent, and not simply money rent, though the two could be the same.

To be clearer about this, consider a company which is thinking of buying some land outright, where it is confident that it will find oil. It will take the land tax into account when deciding whether to buy the land (just as it would take sales tax, etc into account today). The effect of the land tax will be to reduce the price which the company is willing to pay for the land, and so will in effect be paid by the current owner of the land. The landlord will sell to them if what they can pay is more than he could make from the user with the next best use of that land. If the land tax did not exist, the company would pay more, and the landlord would be end up richer. But the person with the second best use of the land would also be willing to pay more, and so the landlord's decision would not be affected by the tax!

Finally, as a couple of the commentators have pointed out, there is a fatal problem with Bryan's argument: the model which he says cannot work in theory already works in practice.
Or do you think that when Western oil companies rock up in Saudi Arabia, that the Saudis don't make them pay every cent for the value of the land/natural resources? The Western oil companies just get to keep the additional profits made by extracting, refining, shipping the stuff.
and (italics added)
I invite you to check out the world of actual oil and mineral exploration, this happens all the time. Very seldom will a party of oil/minerals exploration not have to negotiate with a private/government party who will extract as much rent as they can, and the stuff still gets out of the ground with a profit for the exploration party.

The author mistakes 100% of the rent for being 100% of the value of, in this case, oil. It's not, it's what the exploring party will bid to profitably extract it.
Bryan argues that we should be taxing negative externalities instead. The windfall gains made by the landlord because of the efforts of others is a positive externality which blesses the landlord alone, and this is what the tax is meant to recover.

Ricardian Rent is an amazingly subtle concept. I only understood it properly after I read Tim Harford's The Undercover Economist. I am not an expert on taxation, and it could be that I have got something wrong, but I really doubt it. I think it is much more likely that his ideological preferences caused Bryan to rush to judgement.

Edit: Gulzar's comment below, and his op-ed are well worth reading.

Unearned Income

Why we are so enamored with the idea of paid work? This is not about political preferences. The Right bangs on about welfare queens, the left proclaims the virtues of the working classes. Does anybody like idle people?

Strangely enough, as this article by Samuel Brittan shows, Hayek seems to have had no problem with them, or those of us who merely aspire to be completely idle some day.
Hayek went out of his way to praise the existence of the person of independent means, who was responsible for much of the innovation of the last few centuries -- whether in high culture, in the launch of good causes such as the anti-slavery campaign or the more mundane development of the art of living including a great variety of hobbies and sports which were afterwards taken up by the mass of the population.
At a time when you cannot open a business magazine without being forced to contemplate over-achieving businessmen who have no life outside of work, and when people actually seek out tips for sleeping less, as if sleep were some great conspiracy by Nature to prevent them from realizing their full potential, this is refreshing stuff.
Indeed Hayek went so far as to say that if there were no other way it would be better to grant an independent income to one householder in a hundred chosen by lots than not to have it at all. In the 40 years and more since his Constitution of Liberty was published, productivity in the developed world has made great strides. Are we not now approaching a position where some non-wage income could be available not to one in a hundred but to all citizens?
As with so many other ideas, I first encountered the Citizen's Basic Income (CBI) in Chris Dillow's blog. Now that Europe is in crisis, it will be argued that a CBI is impossible there, but I don't think that is the case at all. The real obstacle is always going to be the ideology of work.
