Consider an Edgeworth economy where there are two citizens, Mr. Cortopassi andMs. Thomas. There are only two goods to be consumed in the economy, Beer and Pretzels. The total amount of Beer is 12 units. The total amount of Pretzels is 12 units.Answer the following: Suppose Mr. Cortopassi has utility for the two goods characterized as U C(B,P)=B+P. Ms. Thomas’s utility function is U T(B,P)=B+P. Identify the points that are Pareto efficient.2. Imagine a simple economy with only two people, Leroy and Percy. If the Social WelfareFunction is W = U L + U P, and the Utility Possibilities Frontier is UPF = U L + 2U P, what will be the societal optimum?3. If James has a utility curve characterized by the function given below, what is hismarginal rate of substitution between goods X and Y? U = 2X1/4Y3/4?4. Consider a simple exchange economy where the marginal rate of transformation betweentwo goods is greater than the marginal rate of substitution for the same goods. Can a Pareto equilibrium be derived?5. Suppose that a competitive firm’s marginal cost of producing output q is given byMC=2+2q. Assume that the market price of the firm’s product is $13.a) What level of output will the firm produce?b) What is the firm’s producer surplus?True/False/Uncertain Questions1. Welfare economics is concerned with individual desirability of alternative economicstates.2. The contract curve is the collection of points where utility curves are tangent in theEdgeworth box.3. The Utility Possibility Curve is derived from utility curves.4. When the First Fundamental Theorem of Welfare Ec onomics doesn’t hold, there is amarket failure.5. Externalities can be difficult to detect in open economies.6. Social indifference curves are the same as a Social Welfare Function.7. A utility possibilities frontier need not incorporate the utility of every individual.8. In equilibrium, the MRT should equal the MRS of all individuals.9. If the market does not allocate resources perfectly, the government can.10. Normative economics is more important than positive economics.Essay Questions1. Social welfare functions can be formed in many ways. They can be additive, meaningthat the all utilities curves are added together. They incorporate the idea of least-best, meaning that the utility of the person with the least is maximized. If you were a central planner for an economy, what type of social welfare function would you create?2. Merit goods have received considerable attention toward the end of this chapter. Canconcerts and other publicly provided services be rationalized using these ideas?3. Why might government intervention be needed in a market?。
