has a convivial party atmosphere and is far more female friendly than a normal
boxing crowd, with 40% of tickets purchased by ladies.
Here is more, with the subheader Swedish Chessboxing Sensation in London. About a year ago, five or so people sent me links about chessboxing for "Markets in Everything." I didn't think it was weird enough to merit inclusion in the series. But now, with the addition of "Swedish" and "ladies" to the mix (or is it the "convivial party atmosphere"?), I think it is weird enough. Here is Wikipedia on chessboxing.

… Having voted against the administration's climate change bill on the record means that at least some of these House Democrats will be able to vote for what emerges from a House-Senate conference later in the year. Therefore, the chances of a climate bill being enacted this year is now much greater than it was 24 hours ago.
That's the ever-perceptive Stan Collender on the politics of the climate change bill.
For years I've been promising Bryan Caplan and Robin Hanson that I would play an afternoon game with them, if only once. And for years I've held out. Since I used to play chess, Scrabble, and other games I cannot claim an intrinsic dislike of gaming. Yesterday I tried to play Kremlin with them but I had to give up after thirty minutes. My head hurt and I was not motivated to impose interesting structure on the game as a life activity. I'm still looking for a simple model of my failure. One hypothesis is that anyone who deals with university administration, as I sometimes do, will have no marginal taste for playing Kremlin.
Tyler and I are looking for a good epigram, quote, maxim etc. which will be placed on the copyright page of Modern Principles of Economics, our forthcoming textbook (micro and macro). It should be no more than a few lines. The person who provides the best entry, as judged by us, will receive a signed copy of our book and, if we use the entry, much gratitude!
Bob Baxley, a soon-to-be-loyal MR reader, asks me the following question:
In considering entering in an online drawing for a bicycle, I read the complete rules. The contest is billed as a random drawing of those entered. But what struck me is that "Before being declared a winner, the selected entrant must first correctly answer, unaided, a time-limited, arithmetical, skill-testing question."(http://www.cervelo.com/contestrules.aspx)
Curious about the occurrence of this rule in other contests, I Googled this long phrase and it turns out it is very common in contest drawings: (http://www.google.com/search?hl=en&rlz=1C1GGLS_enUS291US305&q="correctly+answer,+unaided,+a+time-limited,+arithmetical,+skill-testing+question."&btnG=Search). Shorter snippets of this phrase return even more Google hits.
Any thoughts on why this stipulation is listed in the rules?
Maybe his contest is offering up this question to me. But I cannot answer it unaided. Help!
Chess games, on www.intrade.com, but who cares about that tournament? I'd rather see betting on next year's Topalov-Anand match.
I thank Craig Stroup, a loyal MR reader, for the pointer.
There is a new proposal for chess:
Slight Win: A player wins slightly if any of the following
d. The opponent offers to concede a slight win and he or she agrees,
e. He or she stalemates his or her opponent.
f. Without making a move, a player calls the arbiter and proves that as
a result of her opponent's last move, the same position has occurred thrice.
The player that wins slightly gets 4/6 points, and the player that loses slightly
get 2/6 points.
Why not go further and allow the players to bargain for a split sum of any magnitude? "I offer you .5713 to stop playing now…"
Intelligence Squared has held a series of debates in which they poll ayes and nayes before and after. How should we expect opinion to change with such debates? Let’s assume that the debate teams are evenly matched on average (since any debate resolution can be written in either the affirmative or negative this seems a weak assumption). If so, then we ought to expect a random walk; that is, sometimes the aye team will be stronger and support for their position will grow (aye after – aye before will increase) and sometimes the nay team will be stronger and support for their position will grow. On average, however, we ought to expect that if it’s 30% aye and 70% nay going in then it ought to be 30% aye and 70% nay going out, again, on average. Another way of saying this is that new information, by definition, should not swing your view systematically one way or the other.
Alas, the data refute this position. The graph shown below (click to enlarge) looks at the percentage of ayes and nayes among the decided before and after. The hypothesis says the data should lie around the 45 degree line. Yet, there is a clear tendency for the minority position to gain adherents – that is, there is an underdog advantage so positions with less than 50% of the ayes before tend to increase in adherents and positions with greater than 50% ayes tend to lose adherents. What could explain this?
I see two plausible possibilities.
1) If the side with the larger numbers has weaker adherents they could be more likely to change their mind.
2) The undecided are key and the undecided are lying.
For case 1, imagine that 10% of each group changes their minds; since 10% of a larger number is more switchers this could generate the data. The problem with 1 and with the data more generally is that we don’t seem to see a tendency towards 50:50 in the world. We focus on disputes, of course, but more often we reach some consensus (the moon is not made of blue cheese, voodoo doesn’t work and so forth).
Thus 2 is my best guess. Note first that the number of “undecided” swing massively in these debates and in every case the number of undecided goes down a lot, itself peculiar if people are rational Bayesians. A big swing in undecided votes is quite odd for two additional reasons. First, when Justice Roberts said he’d never really thought about the constitutionality of abortion people were incredulous. Similarly, could 30% of the audience (in a debate in which Tyler recently participated (pdf)) be truly undecided about whether “it is wrong to pay for sex”? Second, and even more doubtful, could it be that 30% of the people at the debate were undecided–thus had not heard arguments in let’s say the previous 10 years that converted them one way or the other–but on that very night a majority of the undecided were at last pushed into the decided camp? I think not, thus I think lying best explains the data.
Some questions for readers. Can you think of another hypothesis to explain the data? Can you think of a way of testing competing hypotheses? And does anyone know of a larger database of debate decisions with ayes, nayes and undecided before and after?
Hat tip to Robin for suggesting that there might be a tendency to 50:50, Bryan and Tyler for discussion and Robin for collecting the data.
Is euchre making a comeback?
I played frequently as a child, as I was taught by my partly Irish grandmother. No one else in my grammar school knew the game. Then I heard nothing about it for more than thirty years. Now, twice in the last month, I've heard the game mentioned in public, "on the street" as it were. What is up?
The alternative is that the question is rarely asked because, in fact, euchre is not making a comeback.
Steve Levitt and Greg Mankiw will join the Obama team. Here is a key paragraph from the blog that broke this important story:
Colleagues at the University of Chicago economics department are cheering the move. “I could not think of a better choice than Steve Levitt to move to Washington and help the Obama team” says Nobel Laureate James Heckman, adding that he expects the job to occupy Levitt for two full Obama administration terms. “We will miss him, but he has an important job to do.”
Last week, ChessBase was apparently ‘forced to cease Internet broadcasting of the Topalov-Kamsky match’. As we noted
in our report on the first match game, live broadcasting of the chess
moves in this match without permission was prohibited by the Bulgarian
Chess Federation (although they didn’t seem to have a problem with
Chessdom’s, Crestbook’s, ICC’s and TWIC’s live coverage). This has led
to heated discussions on this site. The key question here is: can you copyright a chess move at all?
Plus this is transmission over the internet, so which law applies? As I understand U.S. law, you can put chess moves into a book and the players have no rights to residual income from that book. Which is how it should be. Transferring income to chess players is not a goal per se. Useful chess books usually contain many games, and requiring rights permission would make the volume harder to assemble.
Maybe grandmasters would play more games, or play better games, if they could charge for rights of reproduction. When it comes to playing more games, I suspect there is already an ample supply of games and easy reproduction will do more to increase real consumption than spurring more contests over the board. If anything is underproduced, it is the salience of the games which have been played (take a game between two 2550 players and call it "Clash of the Titans" and produce more excitement; most chess players won't know the difference between that and a game between the two best players at 2770.)
And better chess? I believe the effort elasticity is low with respect to residual rights income from reporting of the games.
Comparable debates have been held over residual rights to reporting real time stock prices and NBA scores.
Matt Yglesias asks:
Brad DeLong observes
“In Agatha Christie’s autobiography, she mentioned how she never
thought she would ever be wealthy enough to own a car – nor so poor
that she wouldn’t have servants.”
This kind of thing gets a bit hard to get one’s head around when
thinking about the future. What do you think will be the equivalent 100
years from now of Agatha Christie’s car and servants?
I await your answers.
