Standard caveat: I remain apolitical here. Hat tip to Economist's View, whose discussion of Andrew Leonard's Salon article on some current trade policy touches on a lot of interesting things.
Apparently there's a "Trade Adjustment Assistance" program on the Senate radar. Now, this could be considered sensible economic policy, whether or not you agree with it.
"The Trade Adjustment Assistance program is designed to compensate manufacturing sector workers who are displaced by trade. It includes financial support for education and training, a health care credit, wage insurance and other goodies."
It's a well-worn argument that long-term benefits from trade with other countries might come with short-term costs for those workers who find employment in industries which produce goods most likely to be imported. Social justice might argue for support for such workers; help the worker, not the industry is not an original maxim. It can be applied equally to "dying" industries. If the typewriter industry is becoming obsolete, do you subsidize the typewriter producers or let them die and use your welfare state to support the people who are affected?
Maybe it's too harsh to say that this is not a textbook argument, but one certainly can't gloss over the negatives of any policy, no matter how positive the positives, and, recall, those pesky Principles of Economics said that Trade Can Make Everyone Better Off.
The Salon article refers to this, from The Atlantic, makes the forceful and obvious point (I will paraphrase) that a proper welfare state doesn't ask why, just helps the needy while they need, and that this trade adjustment business is a band-aid, a facsimile of a real solution for the problems of the consequences of harsh and widespread unemployment in whole communities at a time.
Not to wade into the politics where I don't belong, but I like this:
"Preaching the benefits of free trade without being willing to take care of the "losers" created by trade isn't very bright in an election year when workers are feeling squeezed, and the opposition party controls Congress."
Ignoring the electioneering stuff, the direct analog to an economics class or an economic policy debate would be to actually have a proper debate, an acknowledgment that everything isn't always super-awesome. Similarly, the Economist's View take:
"It seems to me that an administration that truly cared about the working class would be eager to find a way to help those who are hurt from trade, that they would make it a high priority and insist it get done, but there's little indication - through actual action - that helping workers hurt from trade, or from economic conditions more generally, is a priority."
This is perhaps one of the biggest economic policy questions: how big should your welfare state be? Design is one thing, but we have a fundamental philosophical question here, which is bigger than technicalities. Let's brawl that one out, historically, globally, politically, morally, economically.
Except for poor old John McCain, who gets kicked again. Hard. I'm on record: I think he is an economist (for a suitable definition of economist). Not Economist's View.
"I think a lot of people are missing the point about John McCain's lack of knowledge about economics... Anyone who really cared about economic policy and its effect on households would have taken the time to become familiar with the basics. How will he know how best to help workers if he has no idea about the underlying economics? If he asked, there are very prominent economists who would be happy to spend an hour once or twice a week - kind of like a principles course - explaining how the economy operates. But he never bothered, never took the time, because he apparently doesn't care enough to give up the time necessary to actually understand the polices he is voting on. I wouldn't mind the ignorance so much if there was any indication at all that he had tried to over come it, any indication he thought it was important enough to learn about, but there isn't."
We're going to give McCain the Principles of Economics course? I just got chills. Surely not the one we give the poor undergraduates? From me:
"A list of "principles" pregnant with loaded statements is not the right way to present our discipline."
Let's not indoctrinate John McCain too!

Economists in fiction: Noboru Wataya
Not to get too "Dear Diary", but I am reading "The Wind-Up Bird Chronicle" by Haruki Murakami, and, lo, the protagonist's brother-in-law is an economist.
On academia:
"Noboru Wataya chose to remain in academe and become a scholar. He was no fool. He know what he was best suited for: not the real world of group action but a world that called for the disciplined and systematic use of knowledge, that prized the individual skills of the intellect."
Noboru's book, a perfect parody of economics books everywhere:
"Noboru Wataya published a big, thick book. It was an economics study full of technical jargon, and I couldn't understand a thing he was trying to say in it... I couldn't even tell whether this was because the contents were so difficult or the writing itself was bad... Two expressions he had coined, "sexual economics" and "excretory economics," became the year's buzzwords."
Freakonomics, anyone? Fashionomics? Freedomnomics? The most delicious morsel of the lot is Noboru's approach to public debate, what could be the credo and the damnation of positivist economics:
"But if you paid close attention to what he was saying or what he had written, you knew that his words lacked consistency. They reflected no single worldview based on profound conviction. His was a world that he had fabricated by combining several one-dimensional systems of thought. He could rearrange the combination in an instant, as needed. These were ingenious - even artistic - intellectual permutations and combinations. But to me they amounted to nothing more than a game. If there was any consistency to his opinions, it was the consistent lack of consistency, and if he had a worldview, it was a view that proclaimed his lack of a worldview. But these very absences were what constituted his intellectual assets. Consistency and an established worldview were excess baggage in the intellectual mobile warfare that flared up in the mass media's tiny time segments, and it was his great advantage to be free of them."
Welcome to our world.

Turning economics research into policy
Hat tip to the inimitable GoodLiberal for pointing me in the direction of an excellent article I would certainly have missed otherwise. It's by Noam Scheiber and it's about Barack Obama's advisers; in particular some of the economic policy advice he's been getting. You can find it here, but get it while it's hot because it might move behind the subscriber's wall at the New Republic. To be clear, the economic policy parts are most interesting to me, but there's more to it than that.
It's interesting both how Scheiber characterizes the type of economic theory that's apparently fueling some Obama policy, and how the path from one to the other winds. There are so many fun lines I might just go ahead and start quoting. On the distinction between academics and nonacademics:
"In economics, it's the academics who are first-rate engineers and the nonacademics who are either dreamers or technicians."
Very well put, though I fear a little harsh on dreamers. Research and teaching in academia are indeed geared towards the sterile positivism; the engineering analogy is well drawn. I do wish we had a bit more dreaming in the dreamy spires of academia though.
The article starts out by describing "behavioral economics", that field that's trying to figure out how people act and how to build it into economics.
"Behaviorists like Thaler believed that the perfectly rational, utterly selfinterested maximizers of economists' imaginations had little in common with actual human beings, who frequently err when making simple calculations, who have trouble with self-control, who often act out of altruism or spite. But what's really interesting is how Thaler and his fellow behaviorists responded to this fairly critical insight. Though rational self-interest was the central tenet of neoclassical (i.e., modern) economics, they didn't take a wrecking ball to the field and replace it with some equally sweeping theory of human behavior."
Behavioral economics is possibly the least revolutionary revolution ever to hit an academic discipline, because, as Scheiber is alluding to, the behavioral school is absolutely not changing or abandoning the methodology of economics. As I've noted before, the "perfectly rational" economic man can happily do whatever the behavioralists want him to do to be more "realistic"; it's therefore not necessary to come up with a whole new way of modeling people.
Instead the behavioral school is writing down models of "perfectly rational, utterly selfinterested maximizers" who act in accordance with the behavioral evidence. That is, writing rationalization of the "irrationality" we observe. Contrast this with the traditional criticism of economic man, which is to throw up ones hands and loudly reject the whole idea of trying to predict what people will do. I prefer the behavioral way.
Anyway, what's coming from having this type of economist on the Obama team?
"For example, one key behavioral finding is that people often fail to set aside money for retirement even when their employers offer generous 401(k) plans. If, on the other hand, you automatically enroll workers in 401(k)s but allow them to opt out, most stick with it. Obama's savings plan exploits this so-called "status quo" bias."
Does it take an economist to suggest this? Of course it does not; the article argues, however, that the "engineers" in academia are the ones who can tell you if the opt-out policy will increase saving or not. That's a nice example of the value of positivist economic science: it gives you the evidence that switching from opt-in to opt-out might increase retirement saving, which is handed off to the policymaker, who says "I want to increase retirement saving", and proposes opt-out. Presto. Did any part of the economic science at the bottom of the pyramid require esoteric math or have an ideological bias? Doubtful.
Here's an even better one:
"Obama wonks tend to be inductive--working piecemeal from a series of real-world observations. One typical [economic adviser Austan] Goolsbee brainchild is something called an automatic tax return. The idea is that, if you had no tax deductions or freelance income the previous year, the IRS would send you a tax return that was already filled out. As long as you accepted the government's accounting, you could just sign it and mail it back. Goolsbee estimates this small innovation could save hundreds of millions of man-hours spent filling out tax forms, and billions of dollars in tax-preparation fees."
How simple, how wonderfully useful that would be. How fickle am I that I would vote purely on the basis of an easier tax return?
"The Clintonites were moderates, but they were also ideological.... The Obamanauts are decidedly non-ideological. They occasionally reach out to progressive think tanks like the Economic Policy Institute, but they also come from a world-- academic economics--whose inhabitants generally lean right."
Oh really? Aside from the repetition of this common error about economists' politics, this implies that the positivist approach to academic economics is bleeding into economic policymaking, drastically shrinking the gap between the science and the normative judgment informed by the science. The crucial distinction remains - for example, I could argue that it's wrong to make people opt-out of a retirement scheme rather than opt-in, a violation of their right to be left alone, and I couldn't be wrong, despite what the science said would happen - but the information on which the policy is based is very close to the policy itself.

Unreal
As someone who laments misperceptions of what economists are and do, the barriers to communication with anti-capitalist groups make me very sad indeed. How did I get there? I was looking for something entirely different when I stopped to read an article by Roy Weintraub talking about neoclassical economics. To someone with my beliefs in what economics is, it's a bit schizophrenic. This is nice:
"Neoclassical economics is what is called a metatheory. That is, it is a set of implicit rules or understandings for constructing satisfactory economic theories. It is a scientific research program that generates economic theories."
This is pretty good news: the beast called "neoclassical economics" is merely a box inside which we concoct scientific theories: inside our box, this would lead to that. Weintraub continues to say that the assumptions of neoclassical economics
"include the following:
1. People have rational preferences among outcomes. 2. Individuals maximize utility and firms maximize profits. 3. People act independently on the basis of full and relevant information."
Of these, 1 is redundant to me because I think rationality is not testable and is therefore irrelevant, especially since it's probably implied by 2, and 3 is at best outdated (economists these days are very interested in the implications of imperfect or asymmetric information). If I was pressed to define neoclassical economics, I think perhaps the definition I would use is similar to 2. I'd say that neoclassical economics is the branch of economics that models entities (individuals, firms, governments, etc) as if they try to get the outcome they like best from the ones that are available.
I disagree more with the stance of the article when Weibtraub repeatedly invokes "the neoclassical vision". The connotations of this phrase probably reinforce the misconception that economists think the box in which neoclassical economics works obeys the same rules as the real world. I doubt a physicist thinks that a vacuum is the same as the real world, just as I doubt that any economist thinks that the abstractions of economic modeling are the same as the real world.
It's true that a positive economist who seeks to explore "what is" should not neglect to examine the differences between abstraction and reality, but again we must ask at what point the value of realism is eroded by its inability to draw any conclusions. I think the real choice we're faced with is the application of the economic method that says "if this unrealistic simplification, then that" versus a shrug of the shoulders; if it were possible to achieve the ideal "if this, then that", who would reject it? Should we stop trying because we can't be perfect?
Perhaps partly because of such confusions, "neoclassical economics", aside from having a silly name, seems to have become something of a lightning rod for the anti-capitalist set as much as it is for economists with different ideas. Google neoclassical economics and you get - on page one - a page from adbusters (an anti-consumerist publication - Wikipedia entry), and a less histrionic "critique of neoclassical economics" by Herb Thompson.
"Neoclassical economists normally treat economic instability as the effect of exogenous, stochastic factors even though nonlinear economics suggests that what may previously have been considered exogenous, or random, may more likely be endogenous to capitalist social formations."
I confess I'm not sure what "nonlinear economics" means (the almighty Google was inconclusive): clearly I, too, have been indoctrinated to the neoclassical cabal. However, I actually think that the quotation touches on an interesting idea. Can we figure out if the primacy of money as a measurement of outcomes "caused" the rise of the capitalist method of organizing resources, or if the capitalist method "caused" the rise of the primacy of money?
A difficult one. For example, to take a typical example of an anti-capitalist complaint, do people buy sweatshop goods because they don't know they're sweatshop goods or because they care more about cheap goods than where they came from? I think the latter is more consistent with "money primacy leads to capitalism" and the former is more consistent with "capitalism leads to money primacy", although I'm sure that could be debated.
It is possible to imagine that incorrect normatization of positive economics - by which I mean the mistaken assumption that some measurable positive economic variable is a measure of the quality of an outcome - actually causes problems within the economic system. People will do what they will, but if a policymaker chooses a policy based on the primacy of money as a measure of the quality of an outcome, there's a real possibility that the system itself is influenced by its measurement.
The Thompson article also includes the following excellent paragraph:
"The 'rational' consumer of the mainstream economist is a working assumption that was meant to free economists from dependence on psychology.... The dilemma is that the assumption of rationality as intertemporally optimising is often confused with, and regularly presented as, real, purposive behaviour. In fact, the living consumer in historical time routinely makes decisions in undefined contexts. They muddle through, they adapt, they copy, they try what worked in the past, they gamble, they take uncalculated risks, they engage in costly altruistic activities, and regularly make unpredictable, even unexplainable, decisions."
First of all, this is crucially wrong: "rationality" is not something that can ever be more than an assumption, unless you think you can test it. Further, assuming rationality does not exclude any of the motivations Thompson talks about. It would be trivial to write down a model of a rational person who "engaged in costly altruistic activities" - I simply have the person care about others and optimize rationally. The assumption that Thompson is really discussing here is the straw man of "rationality equals maximizes money", which I have previously argued is absolutely not an assumption of any economic theory, neoclassical or otherwise.
Beyond that, this is really back to the same problem that the Weibtraub article was getting at: we're doing the "if this unrealistic simplification, then that". There's a strong push in so-called "behavioral economics" to figure out if there's a workable way to first make realistic generalizations on how people behave and second to incorporate them into the unrealistic simplification of neoclassical economics. While that goes on, the economist who seeks to defend his method must be clear on what his unrealistic simplification actually is and what it is used for.
As usual, no-one is fit to judge if the anti-capitalist model is "better" than the capitalist status quo, but I greatly hope that we would be able to talk about what each would mean. If somehow I were able to convince adbusters to sit down with me and I asked them what they wanted to do and what they wanted to achieve, what might they reply? I don't know what they would say, but whatever their answer, I would like to figure out what it would take to achieve their goals, what the consequences of their chosen actions would be, what it would mean for people, not just them or me. I hope they would like to figure that out too. That's positive economics.

Psychologists are evil
This is just an outstanding quotation, from a New York Times article:
"Often introducing money into the exchange — putting it into the marketplace — is what people find repugnant. Mr. Bloom asserted that money is a relatively new invention in human existence and therefore "unnatural."
Economists are asking the wrong question, Mr. Bloom said at the panel. They assume that "everything is subject to market pricing unless proven otherwise."
"The problem is not that economists are unreasonable people, it’s that they’re evil people," he said. "They work in a different moral universe. The burden of proof is on someone who wants to include" a transaction in the marketplace. (Mr. Roth, who acknowledges that "economists see very few tradeoffs as completely taboo," did not take the criticism personally.)"
Sadly, it seems that Bloom was kidding. Isn't it nice that "economists are evil" is a statement that can be mistaken for seriousness, but "psychologists are evil" is so clearly ridiculous?
How can economists plausibly evil, but psychologists cannot? I think the idea that economists "assume that “everything is subject to market pricing unless proven otherwise.”" is wrong. It's a common criticism: economists reduce everything to dollars and cents, trying to measure the value of stuff that's invaluable (the article is talking about how "repugnance" affects trade, using the example of selling organs).
As the social science of the allocation of scarce resources, how could economics operate without trying to figure out some concept of the value of something to someone? I think environmentalists have long despised economists for this reason. Say we're talking about a scarce natural resource, a rain forest for example. Again, positive economic science cannot possibly hope to tell us what the "best" use of this resource is, but it can hope to tell us the consequences of each use. Unfortunately, it's clearly easier to measure, say, the value of this resource to the logger and grazer who seek to use it today than it is to measure the value to humanity of preserving the forest.
Similarly, it's easier to measure the willingness to pay for an organ by a terminally ill individual, and to measure the willingness of another individual to give up an organ, than it is to measure the potential consequences of allowing the sale of organs. The question at hand is: do we do what we can, even given this imbalance, or does the imbalance justify making no valuation, even the ones that are possible? Is attempting to value anything an assumption that "everything is subject to market pricing"?
Trying to understand more about the consequences of a particular allocation of resources is not the same as either propagandizing for that allocation or method of allocation, that is, markets. Even in jest, the charge that we "operate in a different moral universe" is a serious one. It actually makes me very sad, because I'm very familiar with the particular problem of introducing myself as an economist: it alienates a decent percentage of people you meet. ("I'm an economist, but I'm not evil, honest".) Economists are evil, or at least morally bankrupt, to some people. I wish that wasn't the case.
It's understandable. Let's take the ideal world where all positive economics is done scientifically and without normative judgment. Is it surprising that value-neutral economic science seems evil, while value-neutral physics, or chemistry, or psychology, seems like the noble pursuit of knowledge? The Methodology of Positive Economics by Friedman is, again, eloquent on this subject:
"The subject matter of economics is regarded by almost everyone as vitally important to himself and within the range of his own experience and competence; it is the source of continuous and extensive controversy and the occasion for frequent legislation. Self-proclaimed "experts" speak with many voices and can hardly all be regarded as disinterested; in any event, on questions that matter so much, “expert” opinion could hardly be accepted solely on faith even if the "experts" were nearly unanimous and clearly disinterested. The conclusions of positive economics seem to be, and are, immediately relevant to important normative problems, to questions of what ought to be done and how any given goal can be attained.

It's not just confusion between positive and normative economics, between the practice of the science and its interpretation, it's the very attempt to be value-neutral, to be agnostic, that makes economics seem evil. This is all the more true if, as Friedman is arguing, that there's temptation to attach value judgment to positive economics. If there's any hope of us shedding the "evil" tag, this is a temptation that all economists must resist and fight.
"Often introducing money into the exchange — putting it into the marketplace — is what people find repugnant. Mr. Bloom asserted that money is a relatively new invention in human existence and therefore "unnatural."
Economists are asking the wrong question, Mr. Bloom said at the panel. They assume that "everything is subject to market pricing unless proven otherwise."
"The problem is not that economists are unreasonable people, it’s that they’re evil people," he said. "They work in a different moral universe. The burden of proof is on someone who wants to include" a transaction in the marketplace. (Mr. Roth, who acknowledges that "economists see very few tradeoffs as completely taboo," did not take the criticism personally.)"
Sadly, it seems that Bloom was kidding. Isn't it nice that "economists are evil" is a statement that can be mistaken for seriousness, but "psychologists are evil" is so clearly ridiculous?
How can economists plausibly evil, but psychologists cannot? I think the idea that economists "assume that “everything is subject to market pricing unless proven otherwise.”" is wrong. It's a common criticism: economists reduce everything to dollars and cents, trying to measure the value of stuff that's invaluable (the article is talking about how "repugnance" affects trade, using the example of selling organs).
As the social science of the allocation of scarce resources, how could economics operate without trying to figure out some concept of the value of something to someone? I think environmentalists have long despised economists for this reason. Say we're talking about a scarce natural resource, a rain forest for example. Again, positive economic science cannot possibly hope to tell us what the "best" use of this resource is, but it can hope to tell us the consequences of each use. Unfortunately, it's clearly easier to measure, say, the value of this resource to the logger and grazer who seek to use it today than it is to measure the value to humanity of preserving the forest.
Similarly, it's easier to measure the willingness to pay for an organ by a terminally ill individual, and to measure the willingness of another individual to give up an organ, than it is to measure the potential consequences of allowing the sale of organs. The question at hand is: do we do what we can, even given this imbalance, or does the imbalance justify making no valuation, even the ones that are possible? Is attempting to value anything an assumption that "everything is subject to market pricing"?
Trying to understand more about the consequences of a particular allocation of resources is not the same as either propagandizing for that allocation or method of allocation, that is, markets. Even in jest, the charge that we "operate in a different moral universe" is a serious one. It actually makes me very sad, because I'm very familiar with the particular problem of introducing myself as an economist: it alienates a decent percentage of people you meet. ("I'm an economist, but I'm not evil, honest".) Economists are evil, or at least morally bankrupt, to some people. I wish that wasn't the case.
It's understandable. Let's take the ideal world where all positive economics is done scientifically and without normative judgment. Is it surprising that value-neutral economic science seems evil, while value-neutral physics, or chemistry, or psychology, seems like the noble pursuit of knowledge? The Methodology of Positive Economics by Friedman is, again, eloquent on this subject:
"The subject matter of economics is regarded by almost everyone as vitally important to himself and within the range of his own experience and competence; it is the source of continuous and extensive controversy and the occasion for frequent legislation. Self-proclaimed "experts" speak with many voices and can hardly all be regarded as disinterested; in any event, on questions that matter so much, “expert” opinion could hardly be accepted solely on faith even if the "experts" were nearly unanimous and clearly disinterested. The conclusions of positive economics seem to be, and are, immediately relevant to important normative problems, to questions of what ought to be done and how any given goal can be attained. Laymen and experts alike are inevitably tempted to shape positive conclusions to fit strongly held normative preconceptions and to reject positive conclusions if their normative implications - or what are said to be their normative implications - are unpalatable."
It's not just confusion between positive and normative economics, between the practice of the science and its interpretation, it's the very attempt to be value-neutral, to be agnostic, that makes economics seem evil. This is all the more true if, as Friedman is arguing, that there's temptation to attach value judgment to positive economics. If there's any hope of us shedding the "evil" tag, this is a temptation that all economists must resist and fight.
