Re: SAU PAPER

Jack, for 48, I am guessing its like this-

take AVC = 82 - 6q + 0.2q^2

Then after using the first and second order derivatives, we see it reaches minimum point at q = 15

Since the AVC function is u-shaped, then for q>15, AVC must be rising. Thus we can take q=25 (highest possible q value mentioned)

Is it correct? Also, how to do 40, 41 and 44?

Re: SAU PAPER

Q44
Y=k^0.4*L^.6
take log both side, we get
log Y=.4logK+.6logL
then differentiate
d(logy)=.4d(logK)+.6d(logL)
we know that growth rate of capital=8
growth rate of labor=2
put these value in the equation
So
d(logY)=0.4*8+.6*2
3.2+1.2
4.4
so option A

Re: SAU PAPER

Thanks. Could you try out these macro problems please?

Someone please tell me the answer for 10th. Should be d.

Because as per the statement "b" should be zero

and thus LM should be unaffected.

37th is simple.

S1 / S0 = (1 + Iy) ÷ (1 + Ix)

Where,
S0 is the spot exchange rate at the beginning of the time period (measured as the "y" country price of one unit of currency x)
S1 is the spot exchange rate at the end of the time period.
Iy is the expected annualized inflation rate for country y, which is considered to be the foreign country.
Ix is the expected annualized inflation rate for country x, which is considered to be the domestic country.

Use this, you will get.

44th

Y=k^0.4*L^.6
take log both side, we get
log Y=.4logK+.6logL
then differentiate
d(logy)=.4d(logK)+.6d(logL)
we know that growth rate of capital=8
growth rate of labor=2
put these value in the equation
So
d(logY)=0.4*8+.6*2
3.2+1.2
4.4

45th

2.33 Sample variance, so you take n-1 in denominator.

Rest even I dont know.

Re: SAU PAPER

@sonia In ques 44 , what is the difference between growth rate of output and growth rate accounted for by factor accumulation ?
And we are differentiating the function with respect to what ?
