下面的11题是我的期末考范围的作业 希望有高手帮我解题 可以当面教我最好<约在台北捷运沿线皆可> 如果不行就把解题过程寄给我 我会给1500的报酬 以上 希望有好心人帮忙 1. let the utility of the form U(x)=x1*x2/x1+x2 derive theconsumers demand functions and inverse demand functions 2. determine whether the following functions are ordinary demand functions can you find the associated utility function a x1=1/2*(y+p2)/p1 x2=1/2*(y-p2)/p2 b x1=1/4(y+p2)/p1 x2=3/4y-p2)/p2 3. suppose a consumer has an indirect of the form V(p,y)=a*b*y/(a*p1+b*p2) find the associated demand functions and utility function 4. what are the slutsky and hick compensated price change use a graph to show the slutsky and hick substitution effect 5. let n=2 use a numerical example to show that it ispossible that satisfues WARP but (p1-p0)*(x1-x0)>0 6. let A=(a,b,c)=(100,50,10) be the set of outcomes and b~(t*a,(1-t)*c) find the value of t for the utility functions of u(w)=根号w and V(w)=lnw 7. 某研究生效用u(w)=根号w 毕业後有A.B两种工作 A 内勤每月薪资36000 B 行销业务薪资由业绩决定 业绩的机率为P1=0.5 W1=42000 P2=0.5 W2=30000 若仅有B工作可供选择 求研究生愿接受的最低固定薪资并绘图说明 8 证明 <先说明你将如何证明> 单调递增的严格凹函数转换风险趋避的效用含数 风险趋避程度增加 9. prove that if the investors preferences display IARA the risky asset must be an inferior good 10. prove that for any VNM utility function the condition u,,,(w)>0 is necessary but not sufficient for DARA 11.请说明风险性资产的报酬率全为负 Ri<0时 b= --
