(24,B). There are two citizens: A and B. An alternative is defined by x = Individual preferences are represented by uA (x) = xª, u³ (x) = x³. There are only 3 feasible alternatives: x₁ = (0,0), x2 (2, 2), and x3 = (1, 10). xB = 2.1 Which alternatives are Pareto efficient? 2.2 Which alternatives maximize social surplus? Now suppose that A is altruistic and has preferences represented by B u^(x)=x^ + xE 2 2.3 Which alternatives 2.4 Which alternatives are Pareto efficient? maximize social surplus?
