and for 51,i am getting this.....C=1/2 *Yd=0.5(Y-0.4Y)=0.3Y M=1/10(Y) (since it is function of total income)
Y= C+3200+4000+800-0.1Y Y=0.3Y+3200+4000+800-0.1Y 0.8Y=8000 Y=10000 Now with this the other ans also change..can you please verify :) |

i think 27 is 27/99...lte x=0.272727.... now 100x=27.2727..... subtracting both we get 99x=27 ..x=27/99

i think 6 is C.... here is my working
expected waelth is she doesnt buy =100 expected utility= 10 rootover 100=100 If she buys, her expected U= 10root49*(1-p)+10root400*p since she is an expected utility maximizer she will buy when the second term is >100 equating i get p>3/13=51/221 Please verify... |

For intertemporal ques....I m getting r=1/2 as utility function is of perfect subs...but we should not forget that its intertemporal choice ! I mean consumer would never exhaust her income entirely in either period
The budget constraint given here is P*x1 +P*x2/(1+r)=P*1/(1+r) equivalently x1+x2/(1+r)=1/(1+r) Optimal choice condition MRS=Price ratio →1/beta=(1+r) →r=1/beta -1 Now x1=1/2 So BUDGET CONSTRAINT must be satisfied with these two values 1/2 + x2*beta = 1*beta x2=1-1/(2beta) Beta belongs to (0,1) When beta <1/2 x2<0 (not possible) When beta>=1/2 x2>=0 This implies r=1/2 is the only option that satisfies constraint Anyone with the second part of this ques..? |

for the second part: the number of people who wud consume in period A is intergration from 1/2 to 1/1+r of 2..(uniform distri)...which comes out as N(1-r/1+r)..so if the optimal choice period 1 is 1/2..the demand will be N/2(1-r/1+r)

but vaibhav...since the indifference curve will be a straight line,does not it mean that we will have border solution?

Border solution is der only when prices of two commodity differs!
Here u can't say that prices differ....so here in this case I used the normal optimization for interior solution! |

but here the optimization problem will be max x1+Bx2 sub to x+x2/1+r=1/1+r right?this will be linear programming one..will it have an interior solution,?..and lets take a hypo case..lets assume Beta is nearly 1...lets say 0.99999 ...and r=0.75...in this case i wud be better of consuming in period 2 only cuz the the cost of period 1 consumption will be too high...do you think the consumption smoothing objective will apply here?

I don't think it won't be apply here...as u hv absolute values of r and beta in this case!

Yes 27 will be (27/99)...
