跪求高手解答这道题目，急！求！跪求！！

1. Consider a simple economy with twoindividuals, John and Marsha. The economy is endowed with 30 kilograms ofcheese and 30 loaves of bread each month. John and Marsha’s preferences forbread and cheese are given by their marginal rates of substitution of bread forcheese:

                         MRS1= 10/ X1

                         MRS2=5/X2

Where X1 isthe quantity of bread consumed by John and X2 isthe quantity of bread consumed by Marsha.

(1)  Ifeach individual only had one loaf of bread, how much cheese would eachindividual be willing to give up in order to have another loaf of bread?

(2)  In theinitial allocation, each individual has 15 kilograms of cheese and 15 loaves ofbread. Draw the Edgeworth Box diagram for this economy and explain whether theinitial allocation of cheese and bread is pareto efficient.

(3)  Drawthe contract curve for this economy.

第一题答案是10和5，做出来了，主要是第二小题

2Whenseveral people die because of poisoned capsules of Tylenol pain reliever,strict government regulations were enacted to control the packaging of retailpharmaceuticals. Would private markets have reached the same result?

电脑出了点问题，现在修改一下。第二问和第三问是联系在一起的。
第二问：
      画正方形，左下角表示A，右上角表示B，
     底表示x1，高表示x2，边长30表示总资源。
      正方形中心点表示Endowment {（15，15），（15，15）}。
第三问：
     A的无差异曲线簇：以左下角为原点，x2对x1的边际替代率的不定积分，x2=10lnx1+c1
     B的无差异曲线簇：以右上角为原点，x2对x1的边际替代率的不定积分，x2=5lnx1+c2
     两个曲线簇的切点集，构成一条曲线，就是Contract Curve。

第二题两条无差异曲线是不是帕累托最优？为什么？据我理解，如果将X1=15, MRS1=2/3, X2=15， MRS2=1/3,两个MRS是不相等的，所以不是帕累托最优啊

yes

高手，第二题怎么答。我知道私人市场是达不到这种调控的，但是不知道原因，求大侠解答
