On Economics, Wise and Clever and Good and Bad

Commenting on this post, Daniel Kuehn says

I’ve always found that story from Krugman about his sci-fi inspirations surprisingly blatant! Still, I wouldn’t read as much into it as you are. Krugman is not a dunce, and I’m confident he also accepts your reasoning, that:

“incalculably complex and productive social orders emerge from billions of individual actions, where no one of these actions is meant to achieve anything more than improvement in the welfare of the individual actor”

This is not a unique or rare insight that you’re presenting – I’m sure Krugman shares it, even if he differs from you on what to do with it.

Of course the point I make in the post isn’t unique or rare — the economists listed below fully understand it — but I disagree that Krugman shares it in any meaningful way.

A believer in the existence of buttons to push is either overly impressed with his or her own intelligence or simply unaware of the true complexity of any market economy (or both).

It’s true that Krugman is no dunce.  I have absolutely no doubt that his I.Q. is significantly higher than my own — and, more relevantly and much more impressively, that it is significantly higher than that of 95 percent of all other economists.  But intelligence is not the same thing as wisdom.  In fact, I suspect that, after I.Q. reaches a certain (above-average) level, I.Q. and wisdom are negatively correlated with each other.  Cleverness becomes mistaken for insight.  The two are not at all the same.

Although I admire much of Krugman’s academic work, and especially his popular essays explaining the nonsense of talking of nations as being “competitive” or “uncompetitive,” nothing in his work reveals that he understands the economic problem to be as complex as I believe it to be.

This failure, alas, is not unique to Krugman.  Too many economists fail on this front.  Too many economists lack the wisdom to distinguish their theories from the reality that those theories are (or ought to be) meant to illuminate.  (My favorite example of this failure is economists’ tendency to presume that the closer any industry is to being “perfectly competitive,” the greater the contribution to consumer welfare contributed by that industry.)  Too many economists are insufficiently insightful or insufficiently wise to explore the deep premises that inevitably, and typically inadvertently, underlie their theories.

The deepest economic thinkers of the past 50 years, in my opinion, include Hayek, Ronald Coase, Jim Buchanan, Gordon Tullock, Armen Alchian, Harold Demsetz, Julian Simon, Vernon Smith, and Deirdre McCloskey.

I challenge you, for example, to read the Demsetz article linked to just above — at Demsetz’s name — and not come away with an appreciation for how thinking outside of the box can be mind-expanding.  Likewise, I challenge you to read the Hayek article linked to above and not come away understanding more fully that attempts to ‘plan’ any economy are childish fantasies — that the idea of there being any ‘buttons’ to ‘push’ is about as absurd a misconception as is possible in the social sciences.

None of these scholars shines especially brightly on the cleverness front.  None of them (with the possible exception of Vernon Smith) dazzles his or her readers with elaborate mathematics or econometrics.  Each scholar is as much a philosopher as an economist.  Each understands that the chief contribution of economics is to further our understanding of how billions of individuals, no one of whom possesses more than an unmeasurably small fraction of the knowledge required to cause a viable and productive economic order to emerge and grow, interact and mutually adjust to each other.

Not one of these scholars excels at supplying formulae and recipes and instructions for how and when to push buttons.  Each of these scholars understands that society is an order to be explained and understood, rather than a machine to be “designed,” pushed, pulled, planned, or pummeled into looking like something that any human being imagines it “should” look like.

In short, each of these scholars reasons and analyzes more as a great biologist reasons and analyzes — and not as a great engineer reasons and analyzes.  Any biologist who proposed a plan for engineering genes so that, say, humans would become stronger or healthier or handsomer or smarter would be laughed out of his or her profession.  Economists, unfortunately, do the equivalent all the time.  It’s obscene, really — and really unfortunate.

  • We can admit that government intervention will affect the economy. We can even admit that it will appear to produce the desired results, for a time.


    But the reasons for these interventions are usually because people want to avoid the feedback, the consequences of previous actions. This causes an accrual of feedback pressure.


    The feedback pressure for misallocation of resources is to stop the misallocation and reallocate resources to productive endeavors. In the case of the recent meltdown, that meant allowing firms to collapse so the valuable stuff could be separated from the crap.


    It may be that Krugman, et al, realize that they can't manage all the minutia of the economy, but they seem to believe that they can cause the creation of wealth via monetary stimulus, in effect, attempting to psych people into spending as before, ignore the feedback they've been getting from the market.


    The purpose of government intervention is to prevent market actors from responding appropriately to the signals the market is attempting to send to them.


    Government intervention causes market disfunction. This is then, and has often been, called "market failure".


    My question is why do those who cite "market failure" seem to never look a little deeper and inquire if market failure is not really a manifestation of market disfunction caused by government intervention?


    In the market, everything is interrelated.


    By taxing people to support the empire, their ability to buy health care is hampered, taxing them to provide foreign aid reduces their ability to help the poor, and so it goes.


    And it's no more the fault of politicians than it is of voters. Or is it?


    There's a road to hell. At what point along the road do we decide it is unreasonable to go any further?

    Especially considering that the further we go, the more difficult it is to go back.

    But, Daniel, when you do return, if return you must, here, to refrench your memory, my challenge to you below (at I Am a Liberal), still unanswered.


    For the sake of discussion, I concede your position on mathematical economics, that counting was better than thinking, and, counting without numbers, than with them.


    All of that is granted, for the sake of discussion.


    What discussion?


    My challenge to you, and everyone else here, has been to refute my theory of redistribution, presented "above" (at I Am a Liberal).


    And certainly granted too that you could at least appear to do so by means of mathematical symbols, formulae, and codes, as could any charlatan. But, could you rise above that, and refute it in its own terms?


    The best have tried and failed, not the best on Prof Boudreaux' list, but on mine, including Murray Rothbard, Israel Kirzner, our own revered Larry White, the redoubtable Thomas (Hollywood) Hazlett, and even the venerable Henry Hazlitt.


    What they have tried and failed to do was refute my theory by my methodology, logic without mathematics.


    If you can do that, you'll really stand out from the crowd.


  • Methinks

    OK, how about "individuals who make decisions after having been empowered by other individuals through some electoral process to make those decisions".


    No. No individual has ever been empowered through the electoral process to make personal economic decisions for the voter. This is not a communist country and our constitution is not the Communist Manifesto which prescribes exactly the scenario you describe. The only way for one individual to be empowered in such a way here is through Power of Attorney. I don't remember giving one of those to Barney Frank.


    More frightening....regulation, the favourite tool of politicians, by-passes all legislative process. It is essentially government fiat. Increasingly, regulation is used to design the economy - with *ahem* some pretty nasty unintended consequences.


    I hope Don clears this up, but I don't think that the fundamental disagreement is solely about who gets to make the trade-offs. I can't improve on lead pencil's fabulous post on that subject.

  • Lee Kelly

    I do not agree with Daniel on many things, but some of the commentors here are being unfair--he is no muirgeo.


    Sometimes commentors here fall into a familiar trap for libertarians, and attempt to argue that liberty--free minds and markets--can better achieve desirable goals for society than can a more centrally planned economy. But what is desirable for one may not be for another. The problem which "progressives" have with liberty is precisely that: where liberty has prevailed, it has not created the kind of society they would prefer.


    One of the great virtues of a free economy from my perspective is that nobody is responsible--nobody is at fault--for whatever composition of wealth and happiness emerges. Society is not the kind of entity upon which moral judgement is passed, no more than a gathering storm. Unfortunately few appreciate this view, and people like Krugman propose to re-design what nobody has or could ever design in the first place.


    Such people may overestimate their ability to command and control the system, be conceited in their competence to design the economy, but they are assuredly not mistaken that a free market society is not to their liking. What remains is to convince them that the market, despite all its flaws, offers the best trade off for almost everyone.

    RE: "Once again - collectives don't make decisions. Only individuals have the ability to make decisions."


    Oh - I see the issue. OK, how about "individuals who make decisions after having been empowered by other individuals through some electoral process to make those decisions".


    Once again - the disagreement is over whether these electorally empowered individuals should or should not make certain trade-offs. It is not fundamentally over the trade-offs themselves. There is broad agreement in the profession on what those trade-offs are. Obviously there are important disagreements over the nature of the trade-offs themselves, but it's not a disagreement over how complex the economy is, it's not a disagreement over the underlying Smithian logic, and it doesn't seem to be the fundamentaly disagreement that Don is addressing. Don seems to me at least to be addressing a political/ideological/philosophical disagreement with Krugman. He does a very good (albeit exaggerated) job at highlighting that disagreement. I don't think his claims about the disagreement over the "complexity" of the economy are nearly as compelling.

    Daniel said:


    The point being - don't perpetuate the farce that Krugman wants to "design" the economy just because he may advocate more intervention than you do. And don't perpetuate the farce that because he buys into a few books that were published in Cambridge in the 1930s, he somehow rejects the majesty and complexity of the Smithian vision of the economy.

    Krugman might see the complexity of the Smithian vision....but he still thinks he can design it. A proper understanding of the vision (shared by the economists Don cites) would view these two things as mutually exclusive.


    In the long term, any complex system impressed with centrally designed controls cannot improve an economic condition BETTER than an emergent solution can.


    Does Krugman believe this? - I believe, No.


    Does Don? - I believe, Yes.


  • Methinks

    I don't want to be responding too much,


    Why stop now? Besides, you aren't the worst thing that ever happened to this blog.


    but I did acknowledge that that was the fundamental disagreement - whether "collectives" should or should not ethically make those tradeoffs. That's different from a disagreement over the "complexity" of the economy.


    Once again - collectives don't make decisions. Only individuals have the ability to make decisions. The fact that the head of the collective makes the trade-off implies that either the economy is not complex or that he has more knowledge than all other individuals in the economy. So, it is a de facto argument for simplicity of an economy.


    The moral argument of denying individuals the liberty of self direction leads us directly to an argument about the morality of slavery. I thought we were done with that.


    I've tried hard to muster some respect for Krugman, but he undermines my efforts.

    "make the results change by altering variables, but in doing so, they can depart from the real world"


    Ultimately isn't it spending that Keynesians follow, with the assumption that spending will correlate positively with wealth creation?

  • Lee Kelly

    Sam,


    It's interesting isn't it. When an individual's earnings exceed his expenditures, we call the difference "saving". When a business' earnings exceed its expenditures, we call the difference "profit".


    One thing that continues to elude me is why there should be a paradox of thrift, but not a paradox of profit.


    Many economists, like Krugman, seem to think that people should not be saving, but spending, and if they are not willing to do it, then the Federal Government should step up and fill the gap in aggregate demand. Or in other words, if people are not willing to spend their money, then the government should do so instead.


    But according to this logic, shouldn't profit also be a bad thing during a recession? Should the government step in and fill the gap in aggregate demand created when businesses keep down their expenditures?


    I would not dispute that it might increase GDP, but I would dispute that anyone would be any better off (except politicians and their powerful beneficieries).

    "glossing over the fact that humans do often behave in predictable ways. One of the foundations of economics is that humans repond to incentives."


    The salient fact is that there are almost as many different incentives that people respond to as there are people, and even that is always changing. On the margin, the incentives that I respond to are likely very different than the ones you respond to, and different than the ones that I will respond to in 10 years. It is those differences that drive a productive economy.


    But it is also because of the enormous variety of those differences that macroeconomic intervention is a hopeless task with only destructive results.

  • Intelligence can make one adept a constructing arguments, but the appropriateness of such construction still falls back to premises.


    I am thinking that Keynesian economics is excessively focused on accounting.


    They can make the results change by altering variables, but in doing so, they can depart from the real world, and when they become government policy, we are taken along.

  • Stephen

    Don,


    I think you are glossing over the fact that humans do often behave in predictable ways. One of the foundations of economics is that humans repond to incentives. Change the incentives, ie "push a button", and you can often predict the consequences.


    However, where you and Dr. Krugman would disagree is that society can be improved and/or problems can be solved by pushing the button.

  • Government interventions into the economy, bailouts to prevent bankruptcies, for example, constitute button pushing. They are usually meant to correct the failings of previous "button pushing".


    It is true that "buttons" can be pushed and impact the economy, but the feedback delay precludes appropriate correction.

  • Randy

    Daniel,


    "I'm simply saying that we owe Krugman the courtesy of admitting that not all button pushers are in the same boat."


    I see no reason to admit that at all. All I have is a slippery slope argument, but given the history of the Progressives over the last century or so, and the ever greater extent and pace at which they suppress freedom, a slippery slope argument seems valid. Why would you think it not reasonable to assume that the end result of a Progressive state would be a Totalitarian state? I see no reason to assume otherwise.

    Good post, just wanted to mention something about the IQ issue. I suggest reading Malcolm Gladwell's book "Outliers", their is a chapter about IQ in it - and how in a major long-term study the 'geniuses' fared no better than the 'average'.


    What I got out of the book most was this clever analogy -- In basketball, it tends to help to be taller. It's better to be 6 ft than 5ft, and better to be 6'5 than 6 ft. However, this does not mean that someone 7 ft destroys everyone on the court. Up until a point height matters a great deal, then once you pass a certain level - once you're 'tall enough' -- other things matter more (like ball handling, endurance, strength, etc.).


    It's the same with IQ, once you pass a certain level it doesn't matter anymore - other things matter more.


    Krugman, in this analogy, is like that 7ft tall basketball player that everyone assumes is the best their is, only problem is he is actually out-of-shape, has poor reflexes, refuses to play defense, and has the worst shot in the league.

  • Lee Kelly

    Bret,


    I think Dr. Boudreaux wishes to remove said "buttons". And while that may satisfy Don's own wishes, it is only because he desires that each individual be more free to satsify theirs' (except where that involves central planning, of course). Krugman seems to seek the opposite--to override the decisions of free individuals by tinkering with the economy.

  • Daniel Kuehn

    RE: "And just going by the anecdotal evidence of my experience in a country which served as the master experiment for this kind of design - it doesn't work."


    And this was the second fundamental point that I was challenging - that the kind of "button-pushing" that Krugman proposes, and the conditions under which it is appropriate to push those buttons probably bear no resemblance to the extent or purpose of the button-pushing in the country that you lived. Of course that won't satisfy Don or many other people. I'm simply saying that we owe Krugman the courtesy of admitting that not all button pushers are in the same boat.


    Paul Krugman is no Oskar Lange or Hjallmar Schacht. I appreciate Hayek's insights into planning. They ring very true for me. But those insights shouldn't lead us to caricature Krugman or anybody else of that ilk (myself included, preferably!).

    He is and always has been talking about trade-offs that we make as a collective.


    We don't make trade-offs as a collective. Government uses its monopoly on violent force to shove trade-offs down the throats of people over can wield said force.


    In this way, government does "push buttons" and Krugman's support of government pushing these buttons is supported by his desire to remake society (the unwilling collective) into something he desires. Don never said that button pushing doesn't involve trade-offs. If I understood him correctly, button-pushers like Krugman simply believe that they can create a society better than the one that would exist if everyone were left to make their own trade-offs. You may refuse to call that "design", but that doesn't mean it isn't.


    And just going by the anecdotal evidence of my experience in a country which served as the master experiment for this kind of design - it doesn't work. It doesn't work with disastrous consequences. Now, I'm sure you'll agree and tell me that black is white.

    You wrote:

    I think it should also be mentioned that mathematics and econometrics have nothing to do with economics.


    Now watch Daniel fly into a tizzy over that.

  • Lee Kelly

    Harold Demsetz's piece is interesting.


    One of the problems in economics is what Hayek called "scientism". It manifests itself in many forms, but most destructively in a desire to define terms by crude--but easily measured--accountancy records. Concepts such as economic prosperity are reduced to GDP, poverty is reduced to a low level of earned income, barriers to entry are reduced profit-making at a particular some price.


    I was sitting in an economics classroom earlier this week while the professor discussed poverty in the United States. Armed with data, he observed that single mothers had among the highest poverty rate of any (standard) group in the country. Reflecting upon this, I considered a what legislation could be passed to change this unfrotunate situation.


    Since the problem was apparently that single mothers did not have high enough incomes, a novel "solution" occurred to me. If the Federal Government were to make it illegal for single mothers to look after their own children, then they would need to hire someone else to do so. To do this women would need a higher income and, fortuitously, would now have many more free hours in the day to earn it.


    In a desire to be "scientific" and "empirical", economists have tortured the only data they can easily observe: accountancy records. Meanwhile, the goal of understanding and explaining the principles of economics has been relegated. Those who do not see the purpose of studying economics as to better engineer society, usually spend far less time trying to force informative content into data.

  • Stephen

    Daniel,


    It's so simple.


    If it looks like a skunk and it smells like a skunk...


    You continue to give politicians and charlatans like Krugman every benefit of the doubt.


    Krugman merely cloaks his rhetoric in the language and grammar of less radical economics. This is contradictory at its core.


    Contrast that to Don and Russ who at every turn display a rock solid cohesion of thought.


    Krugman is a man divided against himself.


    Obama suffers from similar conflict.


    But the placated masses mistake that inner confusion for thoughtful introspection and consideration.

  • Daniel Kuehn

    Don -

    You have to stop mentioning me in your posts. I think it's going to my head.


    You don't have to sell me on any of those economists you listed... I have a long plane ride tonight and a couple days out of town, so I'm going to print a few of them off to read through.


    My point is simply that your characterization of Krugman and others' view of the economy as: "a machine to be "designed," pushed, pulled, planned, or pummeled into looking like something that any human being imagines it "should" look like" is tiresome, and fundamentally wrong.


    In my experience, Krugman has always recognized inherent tradeoffs that are informed by your shared Smithian view of the economy. He is usually just saying "it's worth trading X for Y". I think you fundamentally disagree with him because you don't see it as government's job to make that decision. What I'm trying to impress upon you is that that is a fundamentally political and philosophical disagreement that you have with Krugman, not an economic disagreement. He doesn't say "nationalize banks - there are no strings attached", "pass a stimulus - there are no strings attached".


    Now, that's not to say that there aren't fundamental economic differences between you two. Obviously there are. But his acceptance of some multipliers, accelerator effects, information asymmetries, and transaction costs doesn't mean he has a simplistic view of the economy that contrasts with the bedrock Smithian view. If anything, I would argue that the Austro/libertarian insistence that these things cannot exist or at least are not important is a more simplistic view of the economy.


    I just think a lot of people gloss over:


    1. The difference between philosophical differences and economic differences, and


    2. The vast similarities on how you view the economy, which are shrouded by some Keynesian frictions or dynamics that you do genuinely differ on.


    The point being - don't perpetuate the farce that Krugman wants to "design" the economy just because he may advocate more intervention than you do. And don't perpetuate the farce that because he buys into a few books that were published in Cambridge in the 1930s, he somehow rejects the majesty and complexity of the Smithian vision of the economy.


    And to your list of links I would just add The Wealth of Nations as well. You don't think Adam Smith offered a few "buttons" in there too?


    "Button" is a bad word for it - and I do fault Krugman for a blunt, sterile analogy. He is and always has been talking about trade-offs that we make as a collective. I know you two part ways on that one for sure... I just wouldn't read too much into it.

    regulations are button pushing.

They are designed to interfere with the natural interactions between free agents.

  • But Don, having read the vast majority of your posts here at Cafe Hayek for several years, it seems you too have a favorite economic button to push - the reduce regulation on all fronts button.


    I certainly understand that's your preference. But how is that different than Krugman lobbying for his preferences?
