....and calibrations can vary markedly from sample to sample and exhibit large uctuations when the time span of a sample is changed. The application of Section 5 is an instance where one might be concerned about the reliability of method of moments calibrations because the empirical results of M uller, Dacorogna, and Picter (1998) and citations therein indicate that a presumption of existence of moments past the second is dubious for data from nancial markets. But why take a chance on the existence of any moment when the assumption is unnecessary A structural problem with method of moments calibration is a lack of ....

....GARCH model (i.e. an integrated or almost integrated GARCH) as generating process for log returns presupposes a tail index of (or close to) 2. However the existing statistical evidence shows quite convincingly that the tails of real log returns are not so heavy; see for example Muller et al. [28] and Embrechts et al. 17] We can offer two alternative explanations for the deviation of from 2. 9 ffl The statistical estimates of are poor. ffl The IGARCH effect is spurious and occurs because the GARCH process is not a suitable model for the data. The first fact has been discussed in ....
