Range voting

A few readers asked me to discuss range voting.  Wikipedia defines it as following:

Range voting (also called ratings summation, average voting, cardinal ratings, score voting, 0–99 voting, or the score system or point system) is a voting system for one-seat elections under which voters score each candidate, the scores are added up, and the candidate with the highest score wins. Range voting was used in all public elections in Ancient Sparta in the form of measuring how loud the crowd shouted for different candidates.[1] Approval voting can be considered to be range voting with only 2 levels (approved (1) and disapproved (0)).

The main question to get out of your head is whether or not range voting satisfies Arrow's Impossibility Theorem.  (In fact it doesn't, most forms of range voting violate the independence of irrelevant alternatives, but don't worry about that!).  There's no major reason why a democratic system should follow all of Arrow's axioms as defined across universal domain, which means you have to rule out the very possibility of paradoxes.  Can anyone do that?  No, not even when you're deciding which book to read next.  (But should you stop reading?  No.)  We do, however, care if the system can:

1. Deliver decent economic growth and an acceptable level of civil liberties.

2. Build consensus and legitimacy going forward, and

3. Toss out the truly bad politicians.

Ideally, we'd even like:

4. The democratic process itself educates people, raises the level of discourse, and makes for a better society.

On those counts, it is not clear what advantage range voting brings over either a two-party winner-take-all system or some form of proportional representation.  Do we really need to count the preference intensity of voters?  That could sooner be harmful in extreme situations.  Do we really need to teach voters complicated aggregation systems?  The relatively well-educated Germans used a "vote twice but ultimately only the party vote counts" form of PR and for decades most of them never understood it and now they are changing it, finally.

Most countries don't use range voting.  Ireland and Tasmania have had some experience with the Single Transferable Vote (STV) system.  What happens is that a bunch of candidates run for each post, party identification is weak, and reps emphasize constituency service.  That's probably the major dominant effect, namely that most systems of range voting weaken political parties.

The bottom line: Range voting is a solution in search of a problem.  The main problems with democracy include poorly informed, irrational, and short-term voters and politicians.  Range voting doesn't cure any of those and arguably by weakening party affiliation it makes some of them worse.

What I’ve been reading

1. Momofuku, by David Chang and Peter Meehan.  This Nelson/Winter treatise on industrial organization teaches you the evolution of recipes and restaurants and (most of all) the mistakes made along the way.  Smokiness is an important concept in Japanese food, pickling and fermentation are underrated cooking techniques, a cook can learn from a heart surgeon, people will pay $80 for a ribeye steak without fancy decor, and you can cook semi-safe sous vide at home (suck the air out with a straw).  Recommended.

2. Appetite City: A Culinary History of New York, by William Grimes.  A book like this has to have something interesting and indeed this one does.  There is an excellent chapter on how oysters once were "New York City food," akin to lobster in Maine or crab in Maryland.  No more.  The rest of the book remains oddly distant from the eating experiences of real people and overall I was disappointed.

3. Googled: The End of the World as We Know It, by Ken Auletta.  In the abstract this is quite a good book and if someone woke up from a time capsule from 1969 you would start him with this.  Too much of it was familiar to me, though.

4. Timothy Egan, Big Burn: Teddy Roosevelt and the Fire that Saved America.  Impeccably written and well-researched, but it bored me.  Spellbinding portraits of characters, etc. Not enough of a point and of course the fire was not what saved America.  Many people like it, though, so don't let me put you off.

5. The Lives of the Brain: Human Evolution and the Organ of Mind, by John S. Allen.  A very good Belknap Press introduction to recent research on cognition, especially cognition and language.  An antidote to many things you have read in Pinker.  It's a bit of a "tweener" book: it doesn't take you "by the hand" through the results but it also doesn't assume that you are a research scientist.  It was written at a good level for me, but some readers may wish for more explanation of the results.

*Fanfare* meta-list for recommended classical music recordings, 2009

Every November I scour the critics' "Want Lists" from Fanfare, my favorite classical music periodical.  Then I go and spend a lot of money.  Here is the list of all the new recordings, from 2009, which were mentioned by more than one critic:

1. Mahler's 4th, conducted by Ivan Fischer.

2. John Adams, Doctor Atomic Symphony.

3. Mahler: The Complete Symphonies, conducted by Leonard Bernstein, remastered edition.

4. Kurtag's Ghosts, by Kurtag and Formenti.

5. John Adams, Transmigration of Souls, and other works conducted by Robert Spano.

6. Oppens Plays Carter, by Ursula Oppens.

Of that list, #6 received the most selections.  Here are the meta-list picks from last year, all of which turned out to be excellent, if you like that sort of thing that is.  I hope to be passing along more meta-lists soon.

The best sentence I read today, 7:46 a.m. edition

Someone once told me that there is nowhere we are more honest than the search box.

That's from still-a-Wunder-but-no-longer-a-Kind Ben Casnocha.  Read the whole post (drawing upon Michael Agger), it's one of the best I've seen in some time.  For instance:

There are some remarkable contrasts between "dumb" searches and "smart" ones. People who start their search "how 2" are more likely to search "how 2 get pregnant" or "how 2 grow weed." People who start their search "how one might" are more likely to search "how one might discover a new piece of music" or "how one might for the rise of andrew jackson in 1828."

Another contrast is between people who type in "is it wrong to" vs. people who type in "is it unethical to."  If you type in "is it wrong to" the first suggestion is "is it wrong to sleep with your cousin."  Number two is (yes, I tested it in Google): "Is it wrong to sleep with your step dad after your mom dies."  If you type in "is it unethical to," the first suggestion is "is it ethical to sell customer information."  Next comes a question about animal experimentation.  You'll see the lists of comparisons behind the first two links offered above.

Whoops!

If you believed all the talk from Chrysler about how our tax dollars would help finance its fast-track electric-vehicle future, you're in for a big disappointment.

Chrysler has disbanded the engineering team that was trying to bring three electric models to market as a rush job, Automotive News reports today. Chrysler cited its devotion to electric vehicles as one of the key reasons why the Obama administration and Congress needed to give it $12.5 billion in bailout money, the News points out.

Caplan on Education

How much does increasing college-going rates matter to our economy and society?

Caplan: College attendance, in my view, is usually a drain on our economy and society. Encouraging talented people to spend many years in wasteful status contests deprives the economy of millions of man-years of output. If this were really an "investment," of course, it might be worth it. But I see little connection between the skills that students acquire in college and the skills they'll need later in life.

If I believed in Austro-Chinese business cycle theory

Most of China's growth this year has been unsustainable, driven by stimulus. China's money supply has risen 29% in the past year. At the government's behest, banks have increased their lending by nearly $1.4 trillion, or 32%, during that time.

That flood of borrowed cash has been channeled into new infrastructure and production capacity. These investments will account for up to half of China's gross domestic product this year, according to some estimates.

A key question is whether China needs all of this investment. Analysts at the London hedge fund Pivot Capital Management say that China already has enough idle steel-production capacity, for example, to match the steel output of Japan and South Korea combined.

Meanwhile, the ratio of investment to GDP is rising, suggesting China's investment is less and less efficient, says Edward Chancellor at Boston asset-management firm GMO.

The combination of soaring investment and dwindling returns was seen in Japan in its asset bubbles in the 1980s and in the "Asian Tigers" just before their crises in the late 1990s, he says.

What does a free service charge signal?

Eduardo Diaz, a loyal MR reader, asks:

A question for you…have you ever compared in the context of "trade repairs" (i.e. garage door repair, plumbing, etc.) the pros and cons of companies that offer free estimates or evaluations vs. companies that charge an inspection charge?   

My intuition would make me hypothesize that: Free estimate company would have a stronger incentive to be nice to get the business.  They might "sugar coat", if they are unethical and think they can get away with holding you up later.  In this model, the customer might feel "obligated" to reciprocate for the courtesy of the free estimate by giving this provider the business. Company that charges for the inspection would have an incentive to be a little more straight with you, this tendency increasing as the inspection charge comes close to cover the cost to the company of the inspection.  Incentive to be nice is less in this case.  Perhaps, the repair techs with "less people/sales skills" might gravitate to this business model.  or perhaps this model attracts more techs that live far away or don't have a "critical mass" of business in a particular area. These trade repair industries are very competitive due to low barriers to entry and difficulty to collude, so I think competition probably drives the cost structure for those companies to a pretty similar point.   Thus, I'd expect my total cost with a free inspection company vs. an inspection-charge company should be the same, assuming I'm properly informed by reading up on-line reviews, getting several quotes, etc. in other words, the no charge companies will need to recoup the cost of all the inspections that don't result in profitable repair work.

If you think you are likely to proceed with the repair work (rather than junk the thing, try to fix it yourself, decide you're in fact a garage door hypochondriac, etc.), you might be more likely to pay the upfront fee for the estimate.  Of course the company knows you will behave this way.  If they have any ability to price discriminate, for the service itself they will charge you a higher price ex post.  You in turn will shy away from this equilibrium.  In essence paying the upfront service charge reveals something about your type, namely that you are eager for repairs.  We're then more likely to see free estimates as the dominant strategy.  Some subset of firms will charge for estimates if they can appeal to customers who in essence want to face price discrimination to ensure higher service quality from the wealthier firms with more valuable long-term reputational franchises.

Alternatively, assume that if you have to pay to learn the price, the said price information is valuable.  Price information is valuable when the market in question isn't so competitive and when search costs are high.  Producers are signaling that their markets are not so competitive when they charge for service estimates and many producers will shy away from letting on about that to their customers. 

Sometimes you can flip this kind of argument.  You, as a customer, might assume that a firm which charged for estimates had especially informed customers.  You might hope to masquerade as another such informed customer and thus patronize such a firm, hoping that it will treat you well because it is used to dealing with informed buyers.  It is an open question whether this equilibrium holds up.

You can spin many other scenarios, those are just some ideas that came to mind.

NASA FAQ 2012

NASA scientists are frequently being asked questions concerning 2012 and for this reason they have created a web page to answer these questions and reassure the public. e.g.

Q: Is there a planet or brown dwarf called Nibiru or Planet X or Eris that is approaching the Earth and threatening our planet with widespread destruction?

A: Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Eris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

Sigh…. I too fear for our planet.
