"if everyone knew that B would provide a superior wall, in less time, for the same money, then they'd have a choice to make" I'm more inclined to think that people would try to bargain hard with the Bricklayer B - "$500 in two hours is a good price for you, pal". After all the thought goes that even for that price B can erect a lot of walls in two weeks (which is A's single wall building time-span), and that's... only fair, right? (in addition) Don't foul yourself that we live only under market-like laws of supply and demand, we're also social creatures that supposedly have to obey social norms. And the norms can be dictated.
