In this paper we propose a maximum entropy estimator for the asymptotic distribution of the hedging error for options … maximising Shannon's entropy subject to a set of moment constraints, which in turn yields the value-at-risk and expected … shortfall of the hedging error. The significance of this approach lies in the fact that the maximum entropy estimator allows us …

Dieser Beitrag befasst sich mit der Untersuchung der Auswirkungen der datenverändernden Anonymisierungsverfahren ’variablenspezifische abstandsorientierte Mikroaggregation’ (vaabMA, im Englischen auch als Individual Ranking bezeichnet) und ’multiplikative stochastische Überlagerung’...

The effects of temporal aggregation and choice of sampling frequency are of great interest in modeling the dynamics of … asset price volatility. We show how the squared low-frequency returns can be expressed in terms of the temporal aggregation … of a high-frequency series. Based on the theory of temporal aggregation, we provide the link between the spectral density …

Indices of financial returns typically display sample kurtosis that declines towards the Gaussian value 3 as the sampling interval increases. This paper uses stochastic unit root (STUR) and continuous time analysis to explain the phenomenon. Limit theory for the sample kurtosis reveals that...
