I have to start by saying that I enjoyed Freakonomics - the author of that book (Steve Leavitt) systematically applied economic thinking to real world problems, drug gangs, teachers changing their students’ standardized test answers, and the impact of an individual’s name on their career prospects. That said, I don't agree with everything Leavitt says, but I appreciate his approach.
I did enjoy the first chapter’s discussion of coffee prices – although I don’t drink the stuff myself. Though on the whole, I didn't find the Underground Economist to be as satisfying as Leavitt's book for some of the following reasons.
1. The "Head Start theorem". This is the idea that in a race, it is possible to change the starting position of each entrant, in order to have every racer cross the finish-line at the same time. Applying this 'insight' to the real world, the author posits it is possible to increase social equity by taxing those who will earn more money, more upfront. The upfront lump-sum tax does not have the market distorting impact of a marginal tax collected at various intervals, i.e. tax Tiger Woods excessively at the beginning of his career and you will not diminish his willingness to work hard and earn as much as he possibly can throughout his career because we’ve already collected all of the tax up front.
This theorem works well in the abstract mathematical world economists use to ply their trade. But simply translating the model, and its implications into the real world presents many problems, let me just mention a few. How do we know, before Tiger actually succeeds at golf that he will earn above average earnings in golf? Second, even if we did know Tiger was incredibly gifted we need to know, at the beginning of his career, with a fair degree of precision his lifetime earnings. (Impossible for the world we live in but quite doable on the blackboard pretend world most economists’ inhabit) Unfortunately the ‘head start’ theorem is just a clever way to 'scientifically' justify progressive redistribution and welfare programs.
2. Only half the Arrow story was told. The head-start theorem comes from Arrow's work building a mathematical economy. However, Arrow's dissertation dealt with something called the 'impossibility theorem'. This is the idea that in a market each of us votes for what we want with our own dollars. So how will democracy work when we vote for what we want and those preferences are aggregated? In a world of subjective value (voters have different preference ordering over at least three alternatives) Arrow found that is was impossible for a social efficient outcome to result, hence the name ‘impossibility theorem’.
Harford recognizes the advantages of markets, and warns us of widespread government failure, but advocates 'keyhole' solutions; the government intervenes in a targeted way to promote a better solution than the market provides.
One of the problems is whose solution? Harford talks as if we would all agree with the ordering of the government’s priorities. Now this would actually work if we all valued the same things, in the same way, at the same time – but how likely is that?
3. One of the great things about Austrian Economics - the economics of Mises and Hayek, is that is very distinct from other free-market thinking. Austrian economics is not interested in describing the 'efficiency' of the market, but rather emphasizes the market is a discovery process. No-one can know with certainty what will be successful tomorrow. Therefore it is important to allow individuals the freedom to experiment. Through this process new and innovative ways to satisfy consumers emerge, sometimes accidentally, (just look at my previous post on Drucker and unexpected success).
Harford makes such a big deal about scarcity power and the need for government to protect us from businesses with such power. But the reality is that scarcity is an initial conditions which spurs entrepreneurship.
An excellent example is copper. As phone lines expanded there were concerns in the sixties and seventies that we would run out of copper in our attempts to connect the globe. Some prognosticators argued copper would become so scarce, and so expensive, the divide between the rich and the poor would become so incredible society might well unravel (one example is Ehrlich's Population Bomb). But history demonstrated that as the demand for copper increased, new and innovative alternatives emerged. Fiber optic cable is not a poor replacement for copper, it is actually much better. It carries signals without needing strengthening, it has greater carrying capacity of signal, it is cheaper to maintain and is less sensitive to the proximity of electro-magnetic fields (e.g. radio). Scarcity spurs entrepreneurship, and innovation in a socially productive way; something the government is unable to do. If, before the invention of fiber optic cable the government stepped in to protect us from using up the entire world's copper supply, it could well have dampened the incentives of entrepreneurs to find alternatives to copper cable. Government intervention to protect people from scarcity power (seen today) normally does more to preserve and manage the status quo (tomorrow) and diminishes chances for new alternatives and substitutes to emerge, which 'creatively destroy' the scarcity power of a product or business.
If you really believed that something approximating the head-start theorem could be implemented in the real world, and that governments could know what was in all of our interests, and that the scarcity power of a product or business would not be eroded through the market process, then you could potentially argue government intervention has the potential to make our lives so much better. Well, I'm not buying.
Note: I find it interesting that Hartford criticizes the U.S health care system and claims it demonstrated the failure of a free market in health care. Here are a couple of gripes with that view.
a. More than 50cents in every dollar spent on health care in the U.S comes from the government purse - how market-based can it be if government is the majority of purchases?
b. Sure Canada is cheaper than the U.S. But cost is only one measure - how about waiting time. If you need a heart operation (a quadruple by-pass can cost upwards of 85K in the U.S and less than half that in Canada). However in the U.S you get the operation, if you need it, within a couple of days. While in Canada you're scheduled, and you could be waiting more than 3 months. Call me crazy, but if I need it, I'd rather have it sooner, even if it costs more.
c. Administration costs are more in the U.S because doctors and surgeons do less admin work. In the U.S their incentive is to do what creates value and earns them money. In Canada, if you’re a surgeon, and you are going to be paid the same whether you fill out paperwork or do one more surgery (which carries the risk of litigation), then on the margin you are going to do more admin work - thus hiding the size of the administration costs in Canada versus the U.S. Hartford is quick to discuss moral hazard in relation to patient behavior in a private health care system, but fails to even mention the same critique of doctor behavior in a nationalized (government provided) health care service.
