Explanation / Answer
Answer)
First we calculate the average return for crash-n-burn computer over 5 year period i.e
(16%+(-16%) + 18% + 28% + 10% ) / 5
= 11.20%
Average inflation = 2.1%
Average T-bill rate = 4.2%
Average real rate for crash n burn computers= [(1+ return)/(1+ inflation)] - 1
=[ (1+0.1102) / (1+0.021) ] -1 = 0.08913 or 8.913%
Average real risk free rate (T-bills) =[ (1+0.0421) / (1+0.021) ] -1 = 2.057%
Average real risk premium = 8.913% - 2.057% = 6.8561%
