Hi guys, I have a problem with the the question in the afternoon part of CFA mock exam, which gives historical equity nominal return, T-bill return and rate of inflation and asks to calculate the risk premium. The correct solution: 1+RP=(1+RR)/((1+RFR)*(1+inflation)) That would make sense, but there’s a seemingly identical question in EOC of reading 52 in CFA Vol 4 (question 13, p.380) where the correct solution is given as 1+RP=(1+RR)/((1+RFR) i.e. here they don’t subtract inflation premium and get a larger RP figure. Am I missing something here is it a mistake on the CFAI side? My guess would be the answer in the exam was the right one…

My guess would be the answer in the > exam was the right one… I have the same problem and I have written to CFA about it. Yet to hear back from them. But, my guess is that the curriculum is correct since Treasury return is ‘Nominal risk free return’ not ‘Real risk free return’.

I’m not sure if T-bill return can be used here as a ‘nominal risk free return’ - it would be ok if we had T-bonds, but T-bills include only short term, but not long term inflation premium. anish: would be great if you could post here any reply you get from CFAI - i’m really curious to get to the truth;)

I will let you know.
