Economia Experimental
Olhaí gente, o prof. Aguirre me sugeriu esta notícia, do New York Times (27.02.03). Eu me lembro que a pessoa deve, quando entra na página do NYT, criar um login e password (eu mesmo tive um por muito tempo). De qualquer forma, vou colocar um trecho aqui e você, se quiser, completa o procedimento de cadastro.
Sim, claro que vale a pena!
ECONOMIC SCENE - Looking Inside the Brains of the Stingy
By VIRGINIA POSTREL
HERE's a game economists play: Player 1 has $10 and can give any dollar amount to Player 2. Player 2 can either accept or reject it. If Player 2 accepts, they both keep the money. If Player 2 rejects it, neither player gets anything.
What should the players do? Arguably, Player 2 should accept whatever is offered, since some money is better than none. Player 1 should thus offer as little as possible: $1. That strategy is the standard game-theory equilibrium.
But that's not necessarily what happens when real people play this "ultimatum game" in laboratory settings with real money on the line. Faced with low-ball offers, many Player 2's reject them. And many Player 1's make more generous offers, often nearly half the money.
