1. This will be a depressing question. The world has two goods: masks (M) and sanitizer (S). Danny is born with an endowment (M=10, S=10) and has a fixed marginal utility of 1 for masks ( MUM = 1) and 0.5 for sanitizer (MUS = 0.5) . His total utility is given by UD = MD + 0.5Sp Steve is born with (M=10, S=10) and has a marginal utility of MUM = Ss for masks and MUS = Ms for sanitizer. His utility is given by US = Ss * Ms . The total endowment must satisfy MD + Ms = 20, Ss + SD = 20 a. [4 points] Is the endowment point on the utility possibilities frontier? Explain
