Brad DeLong Makes a Wishful Mistake: Brad DeLong asserts that the microfoundations of economics point not to a Hobbesian vision of the war of all against all, but rather to Adam Smith's propensities for peaceful cooperation, especially through exchange.
The foundation of microeconomics is not the Hobbesian 'this is good for me' but rather the Smithian 'this trade is good for us,' and on the uses and abuses of markets built on top of the 'this trade is good for us' principle.
Bertram objects that this isn't true, and others in DeLong's comments section further object that modern economics simply does not rest on this Smithian vision. DeLong replies: "Seems to me the normal education of an economist includes an awful lot about ultimatum games and rule of law these days..."
I have to call this one against DeLong….
