The Pundit’s Dilemma

by Henry Farrell on October 18, 2009

“Via Mark Thoma”:http://economistsview.typepad.com/economistsview/2009/10/the-pundits-dilemma.html, Mark Liberman presents us with “The Pundit’s Dilemma”:http://languagelog.ldc.upenn.edu/nll/?p=1824.

Overall, the promotion of interesting stories in preference to accurate ones is always in the immediate economic self-interest of the promoter. It’s interesting stories, not accurate ones, that pump up ratings for Beck and Limbaugh. But it’s also interesting stories that bring readers to The Huffington Post and to Maureen Dowd’s column, and it’s interesting stories that sell copies of Freakonomics and Super Freakonomics. In this respect, Levitt and Dubner are exactly like Beck and Limbaugh.

We might call this the Pundit’s Dilemma — a game, like the Prisoner’s Dilemma, in which the player’s best move always seems to be to take the low road, and in which the aggregate welfare of the community always seems fated to fall. And this isn’t just a game for pundits. Scientists face similar choices every day, in deciding whether to over-sell their results, or for that matter to manufacture results for optimal appeal.

In the end, scientists usually over-interpret only a little, and rarely cheat, because the penalties for being caught are extreme. As a result, in an iterated version of the game, it’s generally better to play it fairly straight. Pundits (and regular journalists) also play an iterated version of this game — but empirical observation suggests that the penalties for many forms of bad behavior are too small and uncertain to have much effect. Certainly, the reputational effects of mere sensationalism and exaggeration seem to be negligible.

(to avoid falling into my own version of this dilemma, I should acknowledge straight up that while I’m disappointed with the Freakonomics phenomenon _ex-post_, I was quite optimistic _ex-ante_ )

I missed out on the book title contest a while back, so here’s my entry. As regards earnestness, i’m riffing off Andrew Gelman, via Kieran, who observes “”pissing off conservatives” is boring and earnest?”

The main point, though, is that the fuss over the global cooling chapter in Levitt and Dubner’s new book is the first occasion, I think, where the refutation of specific errors has taken a back seat (partly because, in this case, it’s so easy) to an attack on contrarianism, as such. The general point is that contrarianism is a cheap way of allowing ideological hacks to think of themselves as fearless, independent thinkers, while never challenging (in fact reinforcing) the status quo. Here’s Krugman and Joe Romm, for example

Pissing off the other crowd

by Kieran Healy on October 18, 2009

Andrew Gelman discusses Superfreakonomics saying,

The interesting question to me is why is it that “pissing off liberals” is
delightfully transgressive and oh-so-fun, whereas “pissing off conservatives” is boring and earnest?

Several years ago bumper stickers appeared that read “Annoy a Liberal. Work hard. Succeed. Be happy.” I was living in Arizona at the time, so they became a routine part of my commute. Possessing neither the blunt empirical thesis of “Guns Bought Your Freedom” nor the slow fuse of “Body Piercing Saved My Life”, the barefaced cheek of the non sequitur made the sticker absurd and irritating at the same time. I remember wondering what a parallel message to conservatives would look like. Sure enough, attempts at rebuttal soon started appearing on (other) bumpers. They were lame — stuff like “Annoy a Conservative. Think for yourself. Defend the Constitution. Balance the Budget.” Noble sentiments, but watery stuff by comparison.

Why did they seem so ineffective a response? Perhaps stronger material was needed. Might “Annoy a Conservative. Burn the Flag. Convert to Islam. Have an Abortion” work better? No. While that kind of thing can have some punch (“Jesus Loves You, But Everyone Else Thinks You’re An Asshole”), it doesn’t seem like the right tack. Instead, the best riposte to the “Annoy a Liberal” sticker is simply the same thing with the target swapped out: “Annoy a Conservative: Work. Succeed. Be Happy”. The effect is more or less the same as the original, especially if placed on the back of your Lesbaru. Temporarily suspending my longstanding irritation at divisions of this sort, much of what passes for “Pissing off Conservatives” is really an effort to rebut some ridiculous charge or other, instead of a genuinely symmetrical attempt to piss someone off. Or, as the story has Lyndon Johnson arguing, it’s better to kick off the conversation in a way that forces the other guy to deny that he’s a pig-fucker.

Philip Glass

by John Holbo on October 17, 2009

Amazon is giving away a whole Philip Glass album: The Orange Mountain Music Vol.I. I’m really, really enjoying it. On the other hand, I’m using it as background music for scanning and doing itsby bitsy Photoshop stuff. It goes up and down and up and down and my hand goes up and down and up and down, and etc., and we seem to be getting on together. When I was in college I hated Philip Glass. I paid a lot for a ticket to a concert, without knowing what I was in for. I was bitterly disappointed. What do you think of the man? Give the album a try, if you are a skeptic.

The Goldman put

by John Q on October 17, 2009

From the NYT on the remarkable profitability of Goldman Sachs

A big reason for Goldman Sachs’s blowout profits this year has been the willingness of its traders to take big risks — they have put more money on the line while other banks that suffered last year have reined in such moves. Executives say there are big strategic gaps opening up between banks on Wall Street that are taking on more risks, and those that are treading a safer path.

Hmm. I’d be willing to take big risks if I knew the Fed and the US Treasury were standing by, ready to pick up all my losing bets. In the circumstances, the guys at GS doubtless stand amazed at their own moderation in creaming off a mere $20 billion for the year.

Cartoon Cavalcade

by John Holbo on October 16, 2009

I got my hands on a pretty good old book, Cartoon Cavalcade (1943) – and if you got your hands on it too, you wouldn’t pay more’n a few dollars for the privilege, my friend. It’s an anthology of American cartoons from the 1880’s to the 1940’s: 450 pages worth, plus editorial matter from the early 40’s, providing a historically interesting perspective on all this history. Following up this much-commented post of mine, I’ll post a Reginald Marsh item from 1934: [click to continue…]

Petition against “impact”

by Chris Bertram on October 16, 2009

Those of you working in higher education in the UK already know about the barbarous proposal to make future support for research depend on a government assessment of its “impact” – in other worlds whether there’s a tangible payoff in terms of economic growth or social policy. Whilst some people — “Wordsworth Country!” — will no doubt be able to spin the positive effects of their works for tourism, and those designing surface-to-air missiles systems will be about to cite the probable benefits to UK exports, others are not so lucky. Medieval French poetry, the metaphysics of holes, set theory … forget it, basically. The comedian David Mitchell had a pretty good column recently on the whole miserable business.

My colleague James Ladyman has launched a petition on the No.10 website to tell Gordon Brown what we think of the idea. If you’re British, even if you don’t live in the UK any more, “pop over and sign it”:http://petitions.number10.gov.uk/REFandimpact/ .

Territory and justice blog

by Chris Bertram on October 14, 2009

Just a brief note about one of my side projects, the Territory and Justice Network. Cara Nine (UC Cork) and I have been funded by the Arts and Humanities Research Council (UK) and the Irish Research Council for the Humanities and Social Sciences for this project. We’ve now had a couple of conferences. The first, in London back in February and now a little workshop in Novi Vinodolski, Croatia last week. We’ve now launched a blog for the project, which is my reason for posting here. Pay us a visit if you are interested in territory, justice, secession, migration and similar issues (especially from a political philosophy standpoint). And drop me a line if you’d like to become involved in the network in some way.

Thought Crime and Mens Rea

by John Holbo on October 14, 2009

Steve Benen ponders John Boehner on hate crimes: “The Democrats’ ‘thought crimes’ legislation … places a higher value on some lives than others. Republicans believe that all lives are created equal, and should be defended with equal vigilance.” Benen: “if Boehner doesn’t want to consider the circumstances behind a violent crime, and doesn’t want to pursue “thought crimes,” then he’d necessarily reject the rationale behind every hate-crime law, right?” Benen goes on to note that, apparently, Boehner does not. He “supports existing federal protections … based on immutable characteristics.” Which Boehner thinks include religion, but not sexual orientation. Who knew?

There is, I think, an even more basic problem, which is theoretically interesting, which I would certainly like to see used to swat down Boehner-style arguments, and which I’ve never actually seen anyone make (but probably I just missed it). Practically all crime is ‘thought crime’ in the good ol’ common law sense of the Latin phrase actus non facit reum nisi mens sit rea – ‘the act does not make guilt unless the mind be guilty.’ If we were to take a strict liability approach to all violent crime we would be obliged to place wrongful death on a par with premeditated murder. (After all, it’s not as though the lives of those killed accidentally are worth less.)

This refutes the notion that there is something sinister and Orwellian about post-Drakonic/post-Hammurabian developments in criminal law. (Damn liberals and their newfangled political correctness!) It doesn’t follow that ‘hate crime’ legislation makes moral and practical sense, of course. We could have that discussion after Boehner is done looking up ‘immutable’ in the dictionary.

Adventures in New Media public relations

by Daniel on October 13, 2009

Wow, I’d certainly like to know the name of the PR agency employed by Trafigura. It couldn’t have been easy to turn a fairly obscure oil trading company into the number one trending topic on Twitter. How do you manage to create that kind of buzz? I certainly hope that the people responsible will be appropriately rewarded.

In general, I have got quite a lot to say in favour of English libel law, and perhaps will for a future “contrarian Wednesday” post. But the current trend toward aggressive use of preliminary injunctions seems to me to be clearly abusive, particularly when (as alleged by Private Eye) some law firms attempt to file for injunctions as late as possible in the hope of getting an inexperienced judge out-of-hours and putting him under pressure. Anyway, this attempt to gag the press has backfired spectacularly, which will hopefully (viz, the McLibel case) make any future would-be muzzlers of the press think twice before pushing too hard.

Looking at Data

by Kieran Healy on October 13, 2009

Jeremy Freese is doing some analysis:

So, the General Social Survey reinterviewed a large subset of 2006 respondents in 2008. They have released the data that combines into one file the respondents interviewed for the first time in 2008 and the 2008 reinterviews of the respondents originally interviewed in 2006. In a separate file, of course, you can get the original 2006 interviews for the latter people.

What has not yet been released, however, is the variable that would identify what row in the first file corresponds to what row in the second file. In other words, you know that person #438 in the reinterview data is somebody originally interviewed in 2006, but you don’t know what person in the 2006 data there are.

Well, especially because the last thing I need to be doing right now is procrastinating, that sounded like a challenge. Just as I have learned that just because there are no microwave instructions for a frozen dinner doesn’t mean you can’t microwave it, just because there isn’t a merge variable doesn’t mean you can’t merge the data. At least if no secure data agreement is involved.

All I have to say is: holy crap. You’d think knowing somebody’s sex, survey ballot (which was kept the same both times), zodiac sign, year of birth, self-identified race, region where they lived where they were 16, whether they lived with their parents when they were 16, whether they lived in the same place they did growing up, who they said they voted for in 2004, their marital status, their education, what they say they did for a living, how many years their mother went to school, inter alia, would allow you to pretty easily pinpoint who is who. I am here to tell you this is not the case.

I was able to devise some convoluted scheme and check how well it was doing thanks to a pretty big clue that I’ll refrain from posting, but even then there ended up being 50 cases that out of 1500 that I wasn’t sure who they were. In general the experience affirmed a fundamental suspicion I’ve had about analyzing survey data: the data seem so much less real once you ask the same person the same question twice.

The real distinction between qualitative and quantitative is not widely appreciated. People think it has something to do with counting versus not counting, but this is a mistake. If the interpretive work necessary to make sense of things is immediately obvious to everyone, it’s qualitative data. If the interpretative work you need to do is immediately obvious only to experts, it’s quantitative data.

More bookblogging! It’s all economics here at CT these days, but normal programming will doubtless resume soon.

Most of what I’ve written in the book so far has been pretty easy. I’ve never believed the Efficient Markets Hypothesis or New Classical Macro and it’s easy enough to point out how the occurrence of a massive financial crisis leading to a prolonged macroeconomic crisis discredits them both.

I’m coming now to one of the most challenging section of my book, where I look at why the New Keynesian program (with which I have a lot of sympathy) and ask why New Keynesians (most obviously Ben Bernanke) didn’t, for the most part, see the crisis coming or offer much in response that would have been new to Keynes himself. Within the broad Keynesian camp, the people who foresaw some sort of crisis were the old-fashioned types, most notably Nouriel Roubini (and much less notably, me) who were concerned about trade imbalances, inadequate savings, and hypertrophic growth of the financial sector. Even this group didn’t foresee the way the crisis would actually develop, but that, I think is asking too much – every crisis is different.

My answer, broadly speaking is that the New Keynesians had plenty of useful insights but that the conventions of micro-based macroeconomics prevented them from forming the basis of a progressive research program.

Comments will be appreciated even more than usual. I really want to get this right, or as close as possible

The Ostrom Nobel

by Henry Farrell on October 12, 2009

To amplify what Kieran has just said – political scientists are going to be very, very happy today. I had seen Lin cited as a 50-1 outsider by one betting agency a few days ago, and had been surprised that she was at the races at all, given that economists tend (like the rest of us) to be possessive of their field’s collective goodies. I’m delighted to see that my cynicism was completely misplaced. But this is also a very interesting statement of what the Nobel committee see as important in economics.

Lin’s work focuses on the empirical analysis of collective goods problems – how it is that people can come up with their own solutions to problems of the commons if they are given enough room to do so. Her landmark book, _Governing the Commons_, provides an empirical rejoinder to the pessimism of Garret Hardin and others about the tragedy of the commons – it documents how people can and do solve these problems in e.g the management of water resources, forestry, pasturage and fishing rights. She and her colleagues gather large sets of data on the conditions under which people are or are not able to solve these problems, and the kinds of rules that they come up with in order to solve them.

Ostrom, Williamson win Econ Nobel

by Kieran Healy on October 12, 2009

I just heard this from a passing radio and initially didn’t quite believe it. Ostrom, in particular, is a terrific choice. She’s at the other end of the spectrum defined on one side by Freakonomics. Which is to say her work is not flashy, it’s very thorough, and it arrives at, you know, correct answers. I bet the Political Scientists are very, very happy today.

Bookblogging: Micro-based macro

by John Q on October 12, 2009

Over the fold, yet more from my book-in-progress, Zombie Economics: Undead ideas that threaten the world economy. This is from the Beginnings section of the Chapter on Micro-based Macro, and covers the breakdown of the Phillips curve and the rise of New Classical and Rational Expectations macro. This (along with the bits to come on DGSE models) is probably the section on which my own background is weakest, so feel free to point out my errors.

I’ve now posted drafts of the first three chapters (+Intro) at my wikidot site, so you can get some context. In particular, before commenting on omissions, take a quick look to see that the point hasn’t been covered elsewhere.

Micro-based macro is here

I’ve got a lot out of comments and discussion so far, and I hope some of this is reflected in what you are reading.
