Sir, when we are faced with such a question in exam where none of the options seem correct we do get marks for leaving it blank, right?? We obviously don't take a guess in DSE but in other exams if we guess and mark an option which looks relatively closer to the answer we're getting, will we lose marks for answering a question which was supposed to be left blank in such a case?

Amit Sir, in ques32, if x1=1/2 then x2=1-(1+r)*1/2
And if r= 1/ß-1 then x2=1-1/2ß And if ß<1/2, x2 will be negative ! Then why are we not considering this? Please help me Sir.... |

In Question number 54, C=0.25x, D=0.75x, and R/D=0.20, also C/D=0.25/0.75, now money multiplier=(C/D+1)/(C/D+R/D)=[(0.25/0.75)+1)/(0.25/0.75)+0.20)]=0.25...so increase in money supply=2000*2.5=5000 units.

@subhyana..able and bernanke defines Cash reserve ratio as Reserve/Deposit and Currency Deposit ratio as Currentcy /Depsoit...Now accd to this book money multiplier is Cu/Dep+1/ Cu/Dep + Res/Dep.... isnt Cu/Dep=0.25 and and Res/Dep= 0.20 right?

R/D is 0.20...but C/D is 0.25/0.75..this is because if x is total money in circulation then according to the question the amount people hold as currency is 25% of x=0.25*x, similarly D=0.75*x..so C/D=0.25/0.75..!!!!!

Consider in this way..people hold 25% of the total money in circulation as cash/currency and 75% as demand deposits...in this case Cu=0.25*x and D=0.75*x..so Cu/D=0.25/0.75..it remains the same...!!!!

Hi
Question 49:Heteroskedascity Accd to the big formula in gujrati(Appendix of chapter 11 page 434),the estimated vale of Sigma Hat is an unbiased estimator of sigma regardless of its relation to X(i)...but accd to answer key of of Amit Sit,it is option C...am i interpretting the the result wrongly? |

The OLS estimates will be unbiased in case of heteroscedasticity..also the estimated standard error terms will be unbiased..this is because the standard error terms will be biased if there is Multicolinearity...in that case the standard error will be infinite and the estimated coefficients will be indeterminate..so unbiasedness of standard error is related to Multicolinearity i guess..!!!

@subhyana..page 396 gujrati says that var (B hat) will be a biased estimator of B in presence of heterosckedasicity :(
