a b Aggregate income > Ois to be distributed among a set IL of individuals to maximize the utilitarian social welfare function cd(y i)where cd > Ofor all i e IL. Suppose that u Show that if p e (0, 1) then income must be distributed equally if and only if cd = W for all i, je IL. Now suppose that cd cdfor all i, j e IL. What happens in the limit as * 0? How about as 1? Interpret.
