NO.PZ2018123101000102 问题如下 Fujioka tells Maalouf thshe hbeen reang about the use of Monte Carlo forwar rate simulation for fixeincome valuation. She asks Maalouf to further explain this approato her. Maalouf replies, “The Monte Carlo approais quite fferent from the binomitree approaI’ve been scribing to you. Some of these fferences inclu:”fferen1: The Monte Carlo approaes not require calibration, wherethe binomitree approaes.fferen2: The Monte Carlo approais typically employewhen cash flows are path pennt, wherethe binomitree approaonly allows one expectecash flow per no, regaress of the path of interest rates.fferen3: The Monte Carlo approaranmly simulates a fixenumber of interest rate paths anvalues the security only across those paths, wherethe binomitree approavalues the security across all possible interest rate paths on the tree.Of the three fferences Maalouf scribes between the binomitree approato fixeincome valuation anthe Monte Carlo simulation approach, he is least likely correregarng: A.fferen3. B.fferen2. C.fferen1. A Monte Carlo forwarrate simulation ranmlygenerates a large number of interest rate paths thwill correctly valuebenchmark bon only chance. A fixeamount, known a ift term, is aeo every forwarinterest rate on every simulatepath to calibrate thesimulation so ththe values estimatefor benchmark bon equtheir marketprices. calibration这个是什么意思呀？
