I did not write CDS Ashima!

[Ashima]

Oh Okay :)

If the sample size is increased, 95% confidence interval
(a) would contract and become precise
(b) would stay the same but be precise.

[Anjali]

I'll go with C

[Anjali]

What was the answer for that labour and capital question where utility function was min(2L,K )
I was stuck between a and d , so I did not attempt that . How did you ppl proceed with it ?

[Granpa Simpson]

I think that the confidence interval will contract, this is because as sample size increases standard error will decrease and t*se will decrease too and if you put it the same on both sides of the confidence limits, the confidence interval contract...e.g suppose beta*=5 and se=4 initially, now if increases then the se suppose goes down to 3.85 in that case u can verify that the region contracts as compared to the initial values..also precision will increase as the standard error will go down!!!!

[Ashima]

The question was
As the sample size increases what will happen to the 95% confidence intervals:
A. it will become more precise
B. it will become narrow
C. it will become wide
D. Both A and B

As n increases, the SE will decrease and the intervals will definitely become more precise. But will they become more narrow?

I mean were they asking about the new intervals or the older ones? How can they be more precise if they become narrow?

So I left it :(

Giffen good is measured according to price.....increase in price increase in purchasing.....so subs effect always be +ve....but Income effect is -ve.....you kindly check H.Varian plz

[Ashima]

How many questions did you attempt Anjali?

And for the capital labour one, even I was confused. But Ron told me that input price ratio doesn't matter for a kinked curve as it is not diff at the vertex. So it would have been a.

I marked it d :(

[Ashima]

Mrittik: H.Varian, page 144! You are getting confused. Its the other way round.

[SoniaKapoor]

CI will contract and become precise
the labour capital ans was a

[Anjali]

I will confirm this substitution ques , and will get back to you all in the evening. For labour capital one , I was confused so left that one. I attempted almost 19-20 ques .

[Nupur]

Can you please write this whole question (capital labor one) along with the options??
