 Here Claudia’s payoffs are depicted on the horizontal axis, and Laura’s payoffs are depicted in the vertical axis. The green shaded region represents the feasible set of payoff vectors \(\Lambda\) where Laura and Claudia make compatible claims, that is where \(x_1 +x_2 \le 1.\) While the payoff vector \(\bu_0 = ({-1},{-1})\) corresponding to the (H,H) outcome represents their nonagreement point.
