Re: divided government
I think the argument goes like this: 1. The policies both parties agree on is smaller in size than what each party advocates individually. I.e., the equilibrium of the bargaining game is smaller than the whole policy space. 2. In general, most of what each party wants is un-libertarian and un-libertarian outcomes are evenly distributed across the policy space, so you'd expect the equilibrium set to be about the same quality as the whole policy space. 3. Therefore, divided government yeilds the least un-libertarian outcomes. Why the specific combination of Dem congrees and GOP executive? I don't know.

Re: Economist IQ?
At Chicago, econ math GRE's tend to be substantially higher than other social science Ph.D.'s. Verbal scores are comparable to humanities Ph.D.'s. Also remember that econ depts take a lot of asian students, which probably pushes down the verbal GRE score. More generally, any time you require math, you get higher caliber people. IMHO, the highest quality social science students tend to be in econ Ph.D. programs. By doing well in calculus and statistics, they've singalled a great deal of ability. This doesn't happen in other fields, and many social science undergrad programs tend to be watered down. For ex, the soc dept at Berkeley (my alma mater) does not require a course in introductory statistics. Instead, they require one semester of quantitative reasoning, which can be fulfilled with just about anything. Contrast that with economics, where you simply can't graduate from a top program without about a year of calculus. OTOH, economists are probably lower IQ than many physical science Ph.D.'s. IIRC from the Chicago statistics on GRE's, it was typical for non-biology science Ph.D.'s to have nearly perfect math scores.

Related to this is the question of whether there really is a median voter. Let's take 10 issues--abortion, gun control, gay rights, trade policy, tax rates, immigration, middle east policy, racial preferences, CO2/global warming policy, and SDI/star wars missile defense. What percentage of the electorate is in the middle quintile (if we could quantify these issues) on all 10?

Re: Levitt article
and on (including work by ICES colleagues)... On balance I would argue that Levitt is indeed unusually clever (in the sense that he comes up with good questions and also finds interesting natural manipulations to study them), but that his particular approach to economic science is not novel: Vernon Smith has been using it for decades. - Dan Correct me if I am wrong, but a big difference between Vernon Smith and Levitt is that Smith focuses mostly on a single area - experimental econ with a cognitive focus - while Levitt is a bit more wide ranging in his interests. Nothing wrong with that, but maybe that's a reason Levitt is so distinctive. Few people have the cleverness to consistently spot interesting puzzles and then have the tenacity to find data that can actually test hypotheses. Of course, the long term interesting question: will such puzzle solving lead to greater economic insight? I think so. In mathematics, such puzzle solvers are good at showing all sorts of cherished ideas are wrong and the evidence accumulated from such research can force people to think in new ways. Also, puzzle solvers are good at finding tricks that can be used to solve other problems. I wouldn't be surprised if Levitt's long term legacy is like that of Paul Erdos the mathematician who was notorious for solving goofy problems, but whose solutions forced people to rethink a lot of math.

Well, we have a lot of data and research on both questions. Financially stable nations with democratic institutions tend not to succumb to dictatorships, while nations that explicitly reject capitalism tend to evolve into dictatorships.

Re: Competition vs. Profits in the NBA
Robin said: The conflict you describe is that some people want more of a fair fight, and others put more weight on wanting my team to win. Of course the second group doesn't want to win via too easy or obvious an advantage. They may want the rough appearance of fairness, but in fact want enough unfairness for them to win. Can we model this behavior as resulting from rational agents, or is some irrationality required to make such a story work? It doesn't seem to require any irrationality. Say insisting on an unfair game brings you benefits but has the cost that people may complain. It seems natural to assume that the costs created by complaint will increase as the unfairness of the game increases. If the complaint-unfairness curve crosses the unfairness-advantage curve, then people will be more more fair. Dictators, for example, have pushed the complain-unfairness curve down by ruthlessly hurting dissidents. In democratic societies, the costs imposed by complaints can be high enough to force people back to the crossing point of the curve.

Re: Marketing vs. Economics
The usual response to someone ought to do X is why not you?. Introductory classes must meet a lot of constraints. They must prepare those who will continue in the tools that are actually used at higher levels. And they must give the rest some tools they can actually use to understand some phenomena around them. Well, first, I am not an economist. Nothing much I say will be taken seriuosly by economists (aside from my friends who have to listen!). I do produce models of rule base behavior, but since they aren't published in econ journals, they'll probably have zero impact in economics. That's ok. That's just the nature of academia. But second, rule based modeling can easily be taught to undergraduates. For example, the Schelling model, as I pointed out in another post, could easily be taught and yeilds simple but important results. Yes, some people are having some success in explaining some kinds of behavior with rules, but such papers have hardly taken over the journals. And I'm somewhat at a loss to think of what particular rules I would teach GMU undergraduates to take up half of an Econ 101 class. Of course one could just grab material from current marketing 101 classes. But is learning to market really that important? I brought up marketing to make a slightly different point. I wasn't arguing that econ classes should become marketing classes. I was arguing that people whose profession is to predict economic behavior seem to do perfectly well without utility maximization theory. A lot of economic behavior seems to be well described by rules rather than searches for optimal behaviors. Couldn't this be a sign that we should consider a fundamental shift in the construction of economic theory? Could it be the case that economic behavior is a continuum? Some large classes of behaviors are probably rule based while others are the result of searching to optimal outcomes. I think the most interesting possibility is to think of some situations as combinations of rules based and classical economic actors (my example was voting - politicians= rational, voters = rule based). Or how about stock markets? Professional investors are probably closer to the rational actor than mompop investors. Small time investors seem to go on gut reaction rules, at leas many of the ones I talked to. How would our understanding of stock markets change if we thought that there was always a mix of rational and rule based actors?

Not sure what you mean by this, but I suspect that is exactly what the stochastic mechanics of the typical general equilibrium model is about. Adressing the idea that complexity undermines attempts at econ's Kuhnian development as a science, I was simply pointing out that some parts of physics deal with complex systems but still have Kuhn style paradigms. Statistical mechanics is one such example: theory behavior gases - a complex system - has dominant theories. The theory of phase transitions might be another example. But you miss my point. I'm arguing that the phenomena physicists study at the core of the discipline are amenable to sufficiently exact theory and exact measurement that you can have decisive paradigm shifts driven by anomalous research results. Economic theory is not as precise so measurement can't provide the sort of strong evidence that one sees in core physics. Fair enough. Measurement definitely would preclude anamoly driven change because adherent of a theory could always claim that measurements do not capture the real story.

However, to satisfy Kuhn's definition of paradigm, there has to also be a classic example and future research has to be derived from the example.

Re: Questions about the stagflation episode...
IIUC, macro was characterized by multiple schools but there was an outstanding critique that the micro picture was flawed or asbent, which served to undermine one popular school. The anomaly didn't serve to usher in a new macro, but unravel some old science, which still has adherents in a modified version. The new macro is still fragmented and there is no consensus yet. Sounds like an example of science as muddling through. Or in Kuhn's terminology, macro is pre-science - a stage where there is no central idea providing coherence for macro. Fabio On Sat, 1 Feb 2003, William Dickens wrote: None of the above. Macro was already fragmented and remained fragmented after the 70s.

What stagflation did was convince people of the correctness of the Friedman/Lucas critique. This set nearly everyone off on a much more determined search for micro foundations for macro theory. I'll go out on a limb and say we still haven't gotten there. Thus Keynesian theory is still taught to undergraduates and it is what is behind most commercial forecasting models (though they may have some new-classical tweaks here and there).

Re: Questions about the stagflation episode...
Well maybe macro *is* in a scientific state, from your description. Sticking to Kuhn's terminology, normal scientific activity occurs when scientists use existing models to solve outstanding issues. From one perspective, maco is organized around general equilibria, and the fighting is over the details of money, capital and labor markets, as you describe. The situation is similar in many branches of physics - people often accept very broad ideas (Newton's mechanics) and then squabble over details, which may seem huge to insiders, but small to outsiders. Also: I've never bought the whole social science is too complex argument for why economics and physical science differ. A lot of the life and physical sciences deal with complex systems - ever study turbulence theory? It's prettty friggin' hard and complex. Or ecology - lot's of interrelated parts. But we still consider them sciences. Fabio in macro-economics.

Economic anamolies and Kuhn

Re: Babynomics
Question: At what can humans engage in economic behavior? Are there studies showing when children learn to trade ? Fabio Humans start to engage in economic behavior as soon as they are born. Trade is not a necessary characteristic of economic behavior. The issue is rather whether infants are consciously choosing their actions. It seems to me that the genetic basis for behavior is the same in an infant as in an adult. Fred Foldvary I think this is a vacuous answer. By that logic, animals are economic actors - animals seem to choose their actions. Perhaps, then, my original question was vague. The question I have is: when do humans start to engage in *sophisticated* economic behaviors not found in animals? For example, at what age are children able to understand the concept of interest?

RE: Journal response times
friend had a paper go three rounds at AER and that took 3 years. I wouldn't be surprised if a lot of bad papers get rejected quickly and that would bring down the average turn around time a lot. That is indeed the case. Journals get many papers of low quality, and it's easy to reject the bad ones out of hand. And remember, most papers could be improved, and will go through a round of revision. But that is irrelevant if you are submitting a good paper that is eventually going to be published. Then you care about the time to publish and its disgraceful at nearly all economics journals. - - Bill Dickens William T. Dickens It's not irrelevant at all, and it's not prima facia disgraceful, at least on the part of journals. First, it's not irrelevant because its a signal that your paper is being taken seriously, rather than a curt this is lame. After having seen some lame papers in my day, this happens more than you might think. Second, don't blame journals - blame your colleagues. It is simply impossible to get decent reviews on papers. Take a non-hypothetical example - my recent article in Rationality and Society. This paper is an agent based simulation of an epidemic where agents engage in a very simple signallying game. Now how many of my colleagues could read that paper? Among sociologists, relatively few. Add into the mix that some might lazy, on sabbatical, have family issues, etc. Then it becomes very hard to get reviewers. That happened when I first submitted it to a health journal - nobody they knew was willing to read a technical model. I know one person whose paper was sent to *ten* reviewers. There were promises that the reviews would come in, but they never did. But what can the journal do? I know among sociology journals and some others, turn around times have been cut by doing the following: reject papers if they don't survive the first RR; reject papers based on a single bad review; accept papers one only two decent reviews if they author has a good track record. I know economics journals have setup incentives, but in general it doesn't seem to have worked if the members of this list are to be believed. So let me conclude by observing that the Journal of Artificial Societies and Simulations is the fastest reputable social science journal I know. It's on line, has a cadre of dedicated reviewers and a very smart editor - so you think papers whiz through the review process. Some papers do appear in print in a month or two, but most take about 6 mo-year to see publication. Why? Simple, humans are slow and the editors wants quality. It simply takes time to have people read through a paper and then have the author thoughtfully respond. While there is a lot of nutty stuff in academia, journals do the best they can given the constraints. If you want decent peer review and not have full-time paid reviewers, this is the best you can get. The only thing you can do to imporve the system is to review the papers you get, and encourage your colleagues to do the same. Fabio

Journal response times
Anyone have any idea why the norm in economics allows referees so much time to do a report? Why its so different from other fields? Is this one of those soft vs. hard field things? Its my impression that the physical science journals all want fast turn around on their referee reports. Anybody know what its like with Anthropology, Sociology, or Political Science? I'd say economics has a pretty decent turn around time. I currently work at the American Journal of Sociology and we usually get papers back to authors in less than 90 days, often 60 days. My experience is that top tier journals do better than second or third tier because they often have prestige and staff, which encourage quick reviewer response. Most sociology journals do much worse than AJS. As far as discipline goes, economics and political science is best because their is consensus on what constitutes decent research and you don't have to master every detail of a paper to assess its quality. The worst is mathematics because you really have to understand every symbol in every equation. Humanities are also bad - you don't have to understand every word, but humanities professors are very unresponsive. On another list-serv, I saw one math professor complain that a 5 page research note had spent *years* at one journal. You can get similar complaints from humanities professors. In the middle are engineering, sociolgy, education and other fields. Most journals get stuff back from 3 months to a year and these fields are in-between fast fields like economics and slow pokes like math. Fabio

Does anyone think, at least in the excerpts we read, that the article attacked libertarian or libertarian-leaning economics as much as it attacked economics generally? David Levenstam It's typical to say that bad science is X, and my political opponents just happen to do X. IMO, it is usually easier to attack an economic theory in this roundabout way than just to confront the idea head on because you really don't have to understand what's going on. Example from my professional life: As is probably obvious, I'm not an economist - I'm a sociologist who takes economics very seriously and I sometimes use economic tools in my research. So I'm always in a position of explaining economic ideas to non-economists and I frequently find that people tend to avoid economic issues. For example, when I explain human capital theory to people, they seem horrified and obsess over whether their sacred cow - education - can be thought of as something as dirty as an investment. Instead of asking whether the idea is internally coherent and has empirical support, they go nuts over just the wording of the theory. Similarly, I find that these articles that trash economics because it is psuedoscientific do the same - they obsess over the wording (the use of math) rather than think real hard about the intuitions behind things. Of course, there is always bad research hiding behind equations - but the equations just express an idea - that can be debated - in a coherent way. Fabio

RE: Republican Reversal
In the real world we have almost 600 in Congress, dealing with innumerable matters more or less simultaneously.

That, which goes through specific committees with specific members, at specific times, during which times specific other things are happening, and other things are reasonably foreseeable (to happen or to avoid). Let me add a very non-economic note to this discussion. The economic approach to studying policy outcomes is essentially some combination of median voter theorem and public choice - ie, how much can the politician screw the voter before getting fired? Some political scientists have taken the approach outlined the above post. They understand policy outcomes as the result of institutions, networks of politicians,lobbyists and gov't bureaucrats and exogenous events (Ie, the terrorist attacks, Enron) that frame policy. The focus here is on the stuff that happens between the voter and the politicians. I don't think these approaches are really in conflict but what they do is capture different parts of the political procss. The median voter thing seems to capture the broad outlines of politics. America won't turn into Sweden just cause Tom Hayden read Robert's Rules of Order one day. Public opinion and honest elections set the broad paramters for what politicians can accomplish. OTOH, the gov't does so much stuff that politicians have to depend on committees, lobbiests (sp?) and gov't agencies to get anything passed. How can a semi-comprehensible law on uranium mining or Alaskan fishing rights be passed without consulting a million committess, the GAO or affeced parties? Furhtermore, all sort of random events may abruptly change how people percieve a law and add to this mix ths interactions between politicans and voters. Remember, you can do anything you want - if you can convince the median voter it was ok! If you buy this second story, then it's quite easy to see how individual policies may deviate greatly from the median voter. Fabio
Autism, brain damage and cooperation
In any case, all of the deficiencies in children's brains you point out more or less sound like extensions of their low absolute IQ. Not really. One listed deficiency is memory. That might be correlated with IQ, but it's certainly not the same as IQ. Analogy: a computer with a small storage capacity might have sophisticated software (analogy with low memory/high IQ). Real world example: Autistic children. Their behavior is described as misbehavior because they simply can't learn how to interact with adults. However, they can perform very complex tasks such as math problems and some autistic people have been able to score well on IQ tests. Abother real world example: In the book Descarte's Error, a well adjusted rail road worker in the 19th century is injured on the job. He recieves a severe trauma to the head which results in localized brain damage. According to the author, the part of the brain which was damaged many scientists believe is responsible for producing emotions, which may conflict with detached rationalist thinking. Once the railroad worker recovered from his injury, he abandoned his job, started to consort with criminals and lived the rest of his life as a con-artist. As far as people could tell, he retained his cognitive abilities but his personality completely changed. My conclusion from such facts is that the ability to conduct normal social interactions is a combination of learning, IQ, percpetion, memory and other mental abilities. You really can't bundle them all together. Child misbehavior is not reducible to IQ, but might be a result of one or more of a deficiency in one or more of these mental abilities. A simple economic model really seems to leave a lot out. Fabio
Re: Autism, brain damage and cooperation
Come on, Fab - pointing out examples of brain differences explaining behavioral differences is hardly convincing evidence that brain differences are the right explanation in this case. My point is that behavior is more than cost-benefit calculations with IQ as an intervening variable. My purpose in citing this kind of evidence is that behavior depends on cognitive faculties which are dependent on well developed parts of the brain. Damasio's book shows some evidence that brain differences *might* lead to behavioral differences. I'm not an anatomist, but I wouldn't be surprised if children's brains simply didn't have all the parts developed for correctly learning social behavior. Yes, there are cognitive abilities with low g-loading, and memory is one. But now that I think about it, I shouldn't have let you get away with citing memory differences in the first place. Children in fact seem to have much *better* memorization ability than adults in numerous respects. Prof. Bryan Caplan It's well documented that long term memory is nil for children less than five years of age (doctors call it pediatric amnesia) and is very spotty until about 12. Maybe children can remember strings of numbers well in labs, but they can't remember things from a year or two ago terribly well. And it's this long term learning that's needed for socialization. Social behavior draws from a large pool of past experience, not the short term memory tested in laboratories. (Do a real world test: ask a 7 year old about how they misbehaved two years ago. If you get anything remotely accurate, I'll buy you lunch.) Also, while were at it, I think you overinterpret the G-loading thing. A G-loading is essentially a factor analysis of responses to a standardized test. Statistically, you estimate a linear model. G - response to Question 1 G - ... Question 2, etc. G is often called a latent factor that is *unmeasured*. See any non-economics statistics book (economists rarely use this and it's not in Golderger, Amimiya or Greene). Then you can test alternative models like G1 - Q1, Q2, Q4 G2 - Q3, Q5, etc. and do model comparisons. IIUC, the psychometric literature has found that the first model has a really good fit while other models have poorer fits for tests of abstract thinking. What is this G? It's a *construct* from the test, not a direct measurement of anything. Which means to assert one single process called IQ is really strecthing it. What you can safely say is that G is the dimension along which test responses vary. This dimension can be the consequence of a bunch of other things and you can collect data to test hypotheses about these more complex models: F1, F2 -- G -- Q1, Q2, Q3. My whole point is that obsessing over G might lead one to ignore the stuff that leads to G. In a lot of these IQ/behavior debates people seems to take extreme positions that IQ is this all powerful explanatory device, or that it is meaningless when it's neither. I really think that some people are more intelligent than others and that this matters alot, but explaining everything in terms of G seems a bit dicey to me. Fabio

Re: double vs. single entry
Double entry means that you have one column for money going out of an account and one column for money going into an account. Thus, it very easy to keep track of cash inflow and outflow (just add up the columns). With single entry, there is more error because you mistakenly count a debit as a credit. The advantage is huge when you have to do things by hand. It also helps you track errors more quickly.

Re: Republican Reversal
These are all good comments on the Republican reversal. Thus, I take it that the list agrees that democracy works pretty well in reflecting the wishes of the voters. Alex I'd say democracy reflects general trend in voter opinion pretty well, although some policies may be way out of whack. For example, who would argue that either Bush or Gore is very far from the median voter (except on abortion)? Or that conservative states like Idaho tend to have more conservative policies? Fabio
Re: Not such a fantastically entertaining paper

Re: In Praise of Pay Toilets
Plausible, but then the question is: *why* do people have a disutility of paying for toilets? Does this fit into any pattern of the sorts of things people have a disutility of paying for? As noted earlier, people did pay for toilets before and it is common in Europe. So it seems we are trying to pay for a rather specific fact, not a general disutility for paying for toilets. Let me also add a peice of anecdotal evidence that retailers offer free toilets to attact customers: A recent NPR show interviewed Hong Kong residents who said they would congregate in McDonald's in the 1960's becuase it was the only place open in the evening that was public, you could hang out and use the facilities. Eventually many such hang outs popped up all over Hong Kong. Fabio
What is a market?

I know this can be a sticky question, but how would you describe the economy of Russia or China, and why doesn't it count as a market? Is it just the lack of the state, or the presence of a state supported system of law, or would the economy of a place like Sweden count? Fabio

Re: Grade Inflation
The effect of this is to draw students away from math, science and economics and towards the softer social sciences. Similarly, within departments students are drawn away from harder graders and towards softer graders. Budgets go where students go! Thus grade inflation causes a *misallocation of resources* (measured in student time or in budgets.) Alex Alex, were you reading the New York Times this morning? Seriously, how much misallocation is occuring? Why is better to have more math and physics majors, and less English majors? Maybe this is in some sense optimal. Why should people who can't do math clog up math classes? English professors are cheaper and more numerous, so maybe lax grading is a way of allowing people to get the degree while not burdening the big money generators of the university. Fabio
Re: PhD Gluts
2) To attract good thinkers to become historians, schools must keep the wage high enough to compete with other disciplines and occupations that require intelligence. Therefore, I think this is a big part of it. Compeitition to get into the best humanities programs is as fierce as law school. It's common for humanities Ph.D.'s from good places to jump to law school if academia doesn't work out. Consider the following fact. There are some nations where many faculty are paid badly, where they could be paid better. In Latin America, there are entire departments and universities that are treated the way we treat adjuncts in American. Consequently, they don't attract the best, and are considered frequently to be not very good institutions. Fabio John-Charles Bradbury, Ph.D.
Re: economic history question
Most observers have always been very surprised that there never was a big demand for socialism in the United States - even at the height of the depression. The New Deal was very much driven by the Executive branch not by Congress - thus I think things could have been quite different had we not had FDR. Alex I don't share that interpretation. I think the American party system was able to absorb and ameliorate the demand for socialism. My take is that the American labor movement was quite like the European socialist movement, and was quite prominent (remember Eugene V. Debs?). But the big parties were able to produce concessions - for ex, TR's trust busting or FDR's New Deal. Fabio

Re: Economics of rank vs. Economics of the most money
Maybe the real puzzle is under what conditions do people maximize rank or total stuff. F It doesn't have to be complicated, but it does have to be specific. A business trying to maximize market share is pretty specific, though with multiple product lines and sets of consumers there remains the question of how to weigh these different market shares. An employer wanting only to minimize the wages of workers of some race is also specific, though we have to distinguish that from them wanting to minimize the consumption of those workers, to minimize the regard in which those workers are held by associates, or to maximize their mating with potential partners who these workers might compete for.

Re: drink prices
Actually, I've dealt with this situation and it's quite different than the drink at a bar. When you hire a (decent) carpenter, they will tell you what additional labor cost, should it be required. A reputable contractor will have this written out before hand, and you will have signed an agreement saying you know extra work might be reuqired @ $X per hour. Contracts are used to control uncertainty. However, when you order a drink/make a hotel call, there is often no menu, or its hidden. People seem to operate with a price range in mind that is acceptable to them. Fabio There are also many situations where the price can change, and alter prior price agreements. Suppose you hire a carpenter to fix a stairway. He quotes you a price. But halfway thru the job, the carpenter discovers rotten pieces that were not previously known, that have to be replaced, and the price increases. You have already contracted and paid some of the expenses; most folks will just go along with reasonable price changes. So often, in such cases, we really don't know the final price. Fred Foldvary

Re: The Median Voter Theorem and Adoption Law
You are misinterpreting the function of these little issues. Little issues don't build up. Little issues tend to be signals to certain constituencies. For example, nobody has ever lost the vote due to rap music, but Clinton in 1992 signalled to many in the democratic party that he wouldn't be held hostage by the Civil Rights wing of the party by bashing rap star Queen Latifah. It's a low cost signal. Nobody will really care if you bash a rap musician. Same for the community investment act (I forget what this even is). I'd guess that few people are explicitely against it, and it's a cheap way to signal to political moderates that urban issues won't be forgotten by either Gore or Bush. Consider a similar move for adaoption law. Unlike rap, adoption workers are considered experts in their field. They could bash you on the talk shows. A politician who goes for adoption law as an issue might get smeared as someone breaking up black families. How do you counter that? Well, you could argue that having any parents is better than no parents, but then you'd get into an emotional, difficult argument with people who think that children get unintentially hurt by different ethnicity parents, and that adoptions are moves by wealthy whites to steal kids from blacks in financial straits. Basically, like most family issues, it's messy and emotional issue that probably wouldn't yeild easy points for a politician. Fabio But politicians spend a lot of energy working on issues that no one has ever lost an election on. To take one tiny example, both Bush and Gore made a loud point about their support for the Community Reinvestment Act. Who votes on that? The logic, I presume, is that positions on a lot of little issues add up. And it isn't the absolute size of the issue, but the size relative to the effort that counts. Prof. Bryan Caplan
Re: The Median Voter Theorem and Adoption Law
Build-up has two meanings in this context. 1)Politicians could send a series of signals to win small groups of voters. 2) Politicians could send a series of signals to large group of voters who need repeated re-assurances that the politician really means what he says. Ie, build up of votes vs. build up of perception. My claim is that the adoption of campaign issues a) does not build up the # of votes because the class of people for whom this is the most pressing issue is small and b) if you try to build up perception on the adoption issue, there is a very good chance you will get whacked because adoption workers can easily mobilize to change public opinion, since they are recognized experts on adoption. And the point of sending that low cost signal is to ... get more votes! And if you send a lot of them, that adds up. care if you bash a rap musician. Same for the community investment act (I forget what this even is). I'd guess that few people are explicitely against it, and it's a cheap way to signal to political moderates that urban issues won't be forgotten by either Gore or Bush. So do the political moderates care or not?! A little. You claim Gore/Bush made a big deal over the Community act, although I see very little compared to other issues. I think they could care less. Translation: Pre-public debate, the median voter wants a different policy; post-public debate, the median voter will want the status quo? That's an interesting story, but it's different from your earlier ones. Prof. Bryan Caplan Incorrect interpretation of what I said. My claim was that adoption workers are well established authorities over adoption, thus it requires effort to combat them. I also claimed that because they are well established experts, they can smear politicians, imposing high costs over them. They change the terms of the debate from does the child have a home? to are we breaking up black families and damaging the child's identity? This is NOT a claim about changing preferences, it's a claim that adoption workers are quite able to change the terms of the debate. I know economists are genetically incapable of understanding the role that rhetoric plays in politics, but adoption is a great example. If you ask a voter if a black orphans should have white parents when there aren't enough black parenets, they'd say yes. If you ask a voter whether black orphan's personality be messed up because his white parents can't relate to him, then many will say no. A lot of politics is jockeying for the median voter, but remember that the median voter is defined by preferences defined over a set of issues. But of course, you can always try to argue with what the choices are, and that's what I'm talking about. Fabio
Re: The Median Voter Theorem and Adoption Law
I think the median voter has the following preferences concerning adoption: same race parents parents different race no adoption. Bryan's point is that adoption workers seem to prefer: same race parents no adoption parents different race. The MVT would predict otherwise. I claim that capture of the adoption business prevents the MVT result. Is there survey evidence that the median voter and adoptions workers have the same preferences? Fabio In this case I don't think the adoption workers preferences are very far from the median voter's preferences regarding general adoption policies. Yes, I think: people are basically afraid of someone taking their kids, and people are not in fact very comfortable with trans-racial adoption. Fabio wrote: A more probably chain of causation is: adoption workers get legislation passed giving them jurisdiction over adoptions (called usurptation in some academic circles), then set up self-perpetuating mechanisms that enforce unpopular policies. Since little is to be gained from combatting these policies, few people bother to fight it.
Re: The Median Voter Theorem and Adoption Law
fabio guillermo rojas wrote: I don't think you should focus so much on the median voter theorem. The logic of median voter theorems is that politicians offer policies that closely resemble the median voter's desires. This assumes that politicians have direct influence over the policy in question. They could have a direct influence if they wanted to. Neglecting a situation you could affect is just as easy for voters to punish as anything else. Prof. Bryan Caplan I still think you are missing the point. By itself, politicians could influence adoption laws and practices. But there are costs imposed by many things: the ability of adoption workers to wage a political campaign for the status quo, the mobilization of allies, the opportunities lost while fighting adoption laws and the fact that not a single major electoral victory as ever been won over adoption law. It's as simple as this: people don't vote over adoption law. If someone tried to campaign on it, I bet they'd get trumped by somebody campaiging over issues that are proven vote getters. Fabio

Haggling:
Mike Kinsey on Slate notes that KMart employees are now allowed to haggle over prices. He notes that with the Internet, merchants can instantaneously raise or lower prices to meet demand instead of industrial revolution style fixed prices. I've posted once or twice about haggling and standard prices and how in developing nations you can haggle over anything. Kinslet's article essentially argues that standard prices are a historical anamoly - if you are in an undeveloped nation, then you don't have the technology to develop reasonable standard prices. If you are in a high tech society, you have the ability to quickly change prices and still derive enough income to stay in busines. In the middel, like the US 1850-2000, prices are standardized. Fabio
