2 0.23624294 1035 andrew gelman stats-2011-11-29-“Tobin’s analysis here is methodologically old-fashioned in the sense that no attempt is made to provide microfoundations for the postulated adjustment processes”

Introduction: Rajiv Sethi writes the above in a discussion of a misunderstanding of the economics of Keynes. The discussion is interesting. According to Sethi, Keynes wrote that, in a depression, nominal wages might be sticky but in any case a decline in wages would not do the trick to increase hiring. But many modern economics writers have missed this. For example, Gary Becker writes, “Keynes and many earlier economists emphasized that unemployment rises during recessions because nominal wage rates tend to be inflexible in the downward direction. . . . A fall in price stimulates demand and reduces supply until they are brought back to rough equality.” Whether Becker is empirically correct is another story, but in any case he is misinterpreting Keynes. But the actual reason I’m posting here is in reaction to Sethi’s remark quoted in the title above, in which he endorses a 1975 paper by James Tobin on wages and employment but remarks that Tobin’s paper did not include the individual-level de

3 0.17764637 692 andrew gelman stats-2011-05-03-“Rationality” reinforces, does not compete with, other models of behavior

Introduction: John Sides followed up on a discussion of his earlier claim that political independents vote for president in a reasonable way based on economic performance. John’s original post led to the amazing claim by New Republic writer Jonathan Chait that John wouldn’t “even want to be friends with anybody who” voted in this manner. I’ve been sensitive to discussions of rationality and voting ever since Aaron Edlin, Noah Kaplan, and I wrote our article on voting as a rational choice: why and how people vote to improve the well-being of others. Models of rationality are controversial In politics, just as they are in other fields ranging from economics to criminology. On one side you have people trying to argue that all behavior is rational, from lottery playing to drug addiction to engaging in email with exiled Nigerian royalty. Probably the only behavior that nobody has yet to claim is rational is blogging, but I bet that’s coming too. From the other direction, lots of people poi

4 0.13801299 1758 andrew gelman stats-2013-03-11-Yes, the decision to try (or not) to have a child can be made rationally

Introduction: Philosopher L. A. Paul and sociologist Kieran Healy write : Choosing to have a child involves a leap of faith, not a carefully calibrated rational choice. When surprising results surface about the dissatisfaction many parents experience, telling yourself that you knew it wouldn’t be that way for you is simply a rationalization. The same is true if you tell yourself you know you’re happier not being a parent. The standard story of parenthood says it’s a deeply fulfilling event that is like nothing else you’ve ever experienced, and that you should carefully weigh what it will be like before choosing to do it. But in reality you can’t have it both ways. I disagree that you can’t have it both ways, for three reasons: 1. Many potential parents do have an idea of what it will be like to be a parent, having participated in child care as an older sibling, aunt, or uncle. 2. The decision of whether to have a child occurs many times: the decision of whether to have a second child

5 0.12727386 921 andrew gelman stats-2011-09-23-That odd couple, “subjectivity” and “rationality”

Introduction: Nowadays “Bayesian” is often taken to be a synonym for rationality, and I can see how this can irritate thoughtful philosophers and statisticians alike: To start with, lots of rational thinking—even lots of rational statistical inference—does not occur within the Bayesian formalism. And, to look at it from the other direction, lots of self-proclaimed Bayesian inference hardly seems rational at all. And in what way is “subjective probability” a model for rational scientific inquiry? On the contrary, subjectivity and rationality are in many ways opposites! [emphasis added] The goal of this paper is to break the link between Bayesian modeling (good, in my opinion) and subjectivity (bad). From this perspective, the irritation of falsificationists regarding exaggerated claims of Bayesian rationality are my ally. . . . See here for the full article, to appear in the journal Rationality, Markets and Morals.

4 0.76913124 1200 andrew gelman stats-2012-03-06-Some economists are skeptical about microfoundations

Introduction: A few months ago, I wrote : Economists seem to rely heavily on a sort of folk psychology, a relic of the 1920s-1950s in which people calculate utilities (or act as if they are doing so) in order to make decisions. A central tenet of economics is that inference or policy recommendation be derived from first principles from this folk-psychology model. This just seems silly to me, as if astronomers justified all their calculations with an underlying appeal to Aristotle’s mechanics. Or maybe the better analogy is the Stalinist era in which everything had to be connected to Marxist principles (followed, perhaps, by an equationful explanation of how the world can be interpreted as if Marxism were valid). Mark Thoma and Paul Krugman seem to agree with me on this one (as does my Barnard colleague Rajiv Sethi ). They don’t go so far as to identify utility etc as folk psychology, but maybe that will come next. P.S. Perhaps this will clarify: In a typical economics research pap

2 0.93301666 157 andrew gelman stats-2010-07-21-Roller coasters, charity, profit, hmmm

Introduction: Dan Kahan writes: Here is a very interesting article form Science that reports result of experiment that looked at whether people bought a product (picture of themselves screaming or vomiting on roller coaster) or paid more for it when told “1/2 to charity.” Answer was “buy more” but “pay lots less” than when alternative was fixed price w/ or w/o charity; and “buy more” & “pay more” if consumer could name own price & 1/2 went to charity than if none went to charity. Pretty interesting. But . . . What’s odd, I [Kahan] think, is the measure used to report the result. The paper (written by some really amazingly good social psychologists; I know this from other studies) goes on & on, w/ figures & tables, about how the amusement park’s “revenue,” “revenue per ride” & “profit” went up by large amount when it used “name your own price & 1/2 to charity.” Yet that result is dominated by random effects — the marginal cost & volume of sales are peculiar to the product being sold &

3 0.92203236 1409 andrew gelman stats-2012-07-08-Is linear regression unethical in that it gives more weight to cases that are far from the average?

Introduction: I received the following note from someone who’d like to remain anonymous: I read your post on ethics and statistics, and the comments therein, with much interest. I did notice, however, that most of the dialogue was about ethical behavior of scientists. Herein I’d like to suggest a different take, one that focuses on the statistical methods of scientists. For example, fitting a line to a scatter plot of data using OLS [linear regression] gives more weight to outliers. If each data point represents a person we are weighting people differently. And surely the ethical implications are different if we use a least absolute deviation estimator. Recently I reviewed a paper where the authors claimed one advantage of non-parametric rank-based tests is their robustness to outliers. Again, maybe that outlier is the 10th person who dies from an otherwise beneficial medicine. Should we ignore him in assessing the effect of the medicine? I guess this gets me partly into loss f

4 0.9178623 1946 andrew gelman stats-2013-07-19-Prior distributions on derived quantities rather than on parameters themselves

Introduction: Following up on our discussion of the other day , Nick Firoozye writes: One thing I meant by my initial query (but really didn’t manage to get across) was this: I have no idea what my prior would be on many many models, but just like Utility Theory expects ALL consumers to attach a utility to any and all consumption goods (even those I haven’t seen or heard of), Bayesian Stats (almost) expects the same for priors. (Of course it’s not a religious edict much in the way Utility Theory has, since there is no theory of a “modeler” in the Bayesian paradigm—nonetheless there is still an expectation that we should have priors over all sorts of parameters which mean almost nothing to us). For most models with sufficient complexity, I also have no idea what my informative priors are actually doing and the only way to know anything is through something I can see and experience, through data, not parameters or state variables. My question was more on the—let’s use the prior to come up

Introduction: Michael Spagat notifies me that his article criticizing the 2006 study of Burnham, Lafta, Doocy and Roberts has just been published . The Burnham et al. paper (also called, to my irritation (see the last item here ), “the Lancet survey”) used a cluster sample to estimate the number of deaths in Iraq in the three years following the 2003 invasion. In his newly-published paper, Spagat writes: [The Spagat article] presents some evidence suggesting ethical violations to the survey’s respondents including endangerment, privacy breaches and violations in obtaining informed consent. Breaches of minimal disclosure standards examined include non-disclosure of the survey’s questionnaire, data-entry form, data matching anonymised interviewer identifications with households and sample design. The paper also presents some evidence relating to data fabrication and falsification, which falls into nine broad categories. This evidence suggests that this survey cannot be considered a reliable or
