An anonymous reader writes "Climate treaty negotiators would do well to have a little chat with some game theorists, according to this article. The fundamental approach they've been taking for the last several years is flawed, these researchers say, and they can prove it. From the article: 'The scientists gave members of a 10-member group their country’s “treasure”: a 20-euro national savings account, plus a fund for spending on emissions reductions that consisted of 10 black chips worth 10 cents apiece and 10 red chips worth one euro apiece. Each person could then contribute any number of these chips to a common pool. The contributed chips represented greenhouse gas reduction strategies that were relatively inexpensive (black) or expensive (red). Players could communicate freely about their plans for how many chips they intended to contribute.'"
