We have learnt that CBA (Cost and Benefit Analysis) is not the only method to choose among different public policies. There is an alternative method that uses Pareto efficiency as a criterion for choosing among public policies. Lets call this method the PE method. Is the following statement true or false? If a policy alternative is chosen according to CBA method then it will still be the chosen alternative if we instead use PE method. Explain.Suppose there are 4 people in an economy: A B C and D. A is in love with B likes C and hates D. B is in love with C likes A and hates D. C is in love with D likes A and does not like B. Finally D is crazy for C likes B and does not like A. Which of the following couplings is not Pareto efficient? Explain.a)A dates B C dates D.b)A dates C B dates D.c)A dates D B dates C.
