A society is composed of 3 individuals named 1, 50, and 100. There are three alternatives: 2, 60, and 90. For each individual i Є {1, 50, 100}, her utility from alternative A = {2, 60, 90} is given by u^i (A) = − |i — A| - where x is the absolute value of x. 2.1 How does each individual rank the three alternatives? 2.2 Which alternatives are Pareto efficient? 2.3 Which alternatives maximize social surplus, i.e., ∑ i Є{1,50,100} u^i (A) Assume that voters vote sincerely. 2.4 Consider a majority vote between alternatives 2 and 60. Which alternative would win?
