Adam's utility function is UA(x, y) = min{3r, 2y} and his initial endowment is w^ = (12, 12). Bob's utility function is UB(x, y) = 2r+3y and his initial endowment is wh = (12, 12). Find the Walrasian equilibrium allocation [(r4, y!). (1", y")] and price ratio p, /p, for this exchange economy. :E lil E
