[ritu]

i will be grateful if smbdy could respond to following queries....

1.dse 2007----question30 on exchange...i solved 27-29 correctly but for 30 i got b but its c in key...

2.dse 2007----question 37 and 38....pls tell in detail

3.dse 2007......question 47

[aditi5000]

hey for 30, just do the same maximisation problem you solved for question 27 but now put the max problem in the perspective of consumer 2 .. and then subtract from the resource to get consumer 1s consumption. for consumer 2, its a normal case of substitute goods so take p1>p2, p1<p2 and p1=p2 and solve for competitive eqbm.

Can you share your approach for 29? how did we get root 2?

[ritu]

put mrs A =mrs B
which gives 2 Y1/X1=a
..now in question 28 u had eqm value of person 1(X1,Y1) as :(root 8, 4  )
so 2.[2/root8]=a
this gives a=root 2

[ritu]

in equated msr coz we are asked for a value of a so that initial eqm is "efficient"

yar i did what u told for 30 but i got option b as answer not c:(

[aditi5000]

Hey use lagrangian and max
L= 2x2+y2 +lambda(12- x2 square - y2 square)
answer is coming :)

[aditi5000]

thank you Ritu :) got question 29 at last!

[ritu]

okz....thanx a lot aditi..must have made a calculation mistake:)

[ritu]

if smbdy knows other questions then pls let me kno..

[aditi5000]

47 .. that cross means intersection. and intersection is distributive

please help  me with dse question 13? how do you check for quasi convexity? and the difference between quasi convex and convex? reply asap

[The Villain]

Hi Sharddha ...There are several ways to do
one is draw the graph of the functions....u will see that x^2 satisfies  quasi concavity
2..
This function is quasi-concave.
To see this, note that Fis a strictly increasing function on R
. Therefore if F(y)is greater than F(x), it must be that
y is greater than x

 thanks ROn. please help me with 33 and 34 as well
