Nunca confia em Hollywood

Leia que o meu amigo e colega Bob Murphy diz sobre of filme "Uma mente brilhante" que trata a vida do economista-matemático John Nash:

Robert Murphy "... had a guy I knew in grad school email me, asking about the bar scene in "A Beautiful Mind," and how to research more on John Nash. Y'all need to know the awful truth about Ron Howard: Actually what is known as "Nash equilibrium" is the exact *opposite* of what was depicted in that scene. That is the equilibrium concept used in non-cooperative game theory, which models things like the Prisoner's Dilemma which you may have heard of. Now Nash also worked on what's called cooperative game theory, and maybe that's what the script writers had in mind, but my hunch is that they had no freaking clue what they were talking about, and thought it would be dramatic to show Nash overturning Adam Smith.So if you want to google stuff, try "nash equilibrium" and "cooperative game theory" and maybe "nash solution cooperative game theory." But remember, the standard "Nash equilibrium" that will be the first thing in wikipedia, is the exact opposite of what they were doing in that bar scene."
