pls give some hints


48 ) shouldn't it be minima ???

Hi Maahi.. :)

23) Refer the following link:
http://economicsentrance.weebly.com/forum.html

25) Find the market demand.And then equate market demand with market supply.

27) Agent1 is a first mover. So, maximise his utility wrt to his budget constraint. Then, after that whatever is left will be consumed by Agent 2 as his utility is increasing in both the arguments. That point will be PE.

28) Clearly, the above allocation is PE because there is a bound on Agent's1 ability to consume.

29)Equate the MRS and substitute the values to allocations you got in 27.

30) Now, Agent 2 is a first mover. Do, maximise his utility first and then, check for Agent 1.

36) Just total differentiate Y=C+I+G. Divide it by (∂Y).Plug the value of (∂i/∂Y). You'll get ∂Y/∂G.

Plz anyone tell me how to solve ques 51 and 53? Dse 2007

[Do bats eat cats?]

I'd appreciate help with q.53 too.

53. Suppose that each person out of a group of 4 friends is randomly assigned to one of 6
classes. What is the probability that no class has more than one person from this
group?

The answer is 5/18.

[Ankit]

Here:

There are 6 classed and 4 people to be assigned in each so that there is no overlap:
1) first person has 6 options
2) second has 5
3) third has 4
4) and last one has 3

Total cases = 6^4 (when each has 6 options) or visualize it as balls in urns problem

P= 6*5*4*3/(6^4)

Cheers Ankit! Can't believe I couldn't figure that out. I think the stress is turning me into a brain dead zombie :/

hi ankit d link is broken if u have  d notes wala pdf then plz send it to me @[e-mail] .

thanks :-)

[Kogo]

Thank you ankit...:)

ca't get it . plz see its noise and praful wala ques . its nt there in d link
25) Find the market demand.And then equate market demand with market supply.  
 i m getting 6 n nt 9 plz see

got others thanks :-) plz try other ques stoo

 i did q 37 as stated here . plz see where i m wrong ...


37 ) u = log c1 + 1/1+ delta log c2

u = log c1+ 1/ (1+delat) log { y2  - (1+r) (c1-y1) }

du/dc1 =  1/c1  + 1/(1+delta) * 1/ { y2- (1+r)(c1-y1) * - (1+r)

hey duck i didnt get your approach for 27,coulld u plzz explain again.

[The Villain]

Even i have a doubt on quest 27...someone pls help!

[kangkan]

@ron: the budget constraint for agent 1 is the circle X^2?+Y^2<=12 with the additional constraint of X<3 and Y<3.....he is trying to maximize x^2*y subject to this budget constraints(s)..draw the graphs..the answer will be point where the the the curves are tangent....it will become apparent

[The Villain]

@Kangkan...i tried drawing the graphs bt i'm not really getting it :-( ..pls help

[kangkan]

dont worry..i will try to upload a pic tomo...right now no power here...2 dark to take a pic

[The Villain]

Thanxx a lot...this power cut is annoying i know...Thankfully nothing as such here..

[kangkan]

Hi...we know that the the pic that optimum will be where the indiff curve is tangent to the budget curve..

Slope of indiff curve =2y/x ....slope of budget curve is 2x/2y

Equatiing we get, x= root over 2*y

now this must satisfy the equation of the circcle ..putiting it in X^2 +y^2=12, we get y=2 and X=rootover 8..ths satisfies the constraint that X<3 and Y<3..so no problem

I hope this helps

Thanxxx Kangkan :-)
