1. Consider an economy with two consumers and a total initial endowment W=(2, 2) a. Give an example of one allocation that is non-efficient and envious when the utility functions are uA (X1, X2) = X1 + x2 and UB (X1, X2) = X1 + X2 b. Give an example of one allocation that is efficient and non-envious when the utility functions are uA (X1, X2) = 4 and up (X1, X2) = X1 + X2. Give also an example of one allocation that is non-efficient and non-envious, another one that is efficient and envious and another one that is non-efficient and envious
