Column Left Right Up -1,-1 -10,0 ROW Down 0, -10 -8, -81.4 Do you recognize this game from your reading or the lecture? You can do a linear transformation on the payoffs of a game without changing its essential structure. In fact, you can even do more general monotonic transformations, though that will affect the probabilities in a mixed strategy equilibrium. Which game is disguised under the action names of Game 1?

A positive monotonic transformation take each payoff combination X, Y and transforms it to f(x), f(Y), where the function f is such that if a is greater than b, then f(a) is greater than f(b). Linear transformations are monotonic, but so are others. For example, apply the transformation f(x) = (x+10) squared to Game 1: GAME 1b
