Reducing size distortions of parametric stationarity tests
Lanne, Markku; Saikkonen, Pentti - 2000
The use of asymptotic critical values in stationarity tests against the alternative of a unit rot process is known to lead to overrejections in finite samples when the considered process is stationary but highly persistent. We claim that in recent parametric tests this is caused by estimation...

Efficient hedging for a complete jump-diffusion model
Kirch, Michael; Krutchenko, R. N.; Melʹnikov, Aleksandr V. - 2002
This paper is devoted to the problem of hedging contingent claims in the framework of a complete two-factor jump-diffusion model. In this context, it is well understood that every contingent claim can be hedged perfectly if one invests the unique arbitrage-free price. Based on the results of H....

Probabilistic aspects of financial risk
Föllmer, Hans - 2000
Problems arising in Finance have become a significant source of new developments in Stochastic Analysis. We discuss some recent case studies, in particular some decomposition and representation theorems which are motivated by problems of hedging derivatives and of intertemporal consumption choice.

Discrete time option pricing with flexible volatility estimation
Härdle, Wolfgang; Hafner, Christian M. - 1997
By extending the GARCH option pricing model of Duan (1995) to more flexible volatility estimation it is shown that the … prices of out-of-the-money options strongly depend on volatility features such as asymmetry. Results are provided for the …

Implied volatility string dynamics
Fengler, Matthias R.; Härdle, Wolfgang; Mammen, Enno - 2003
A primary goal in modelling the dynamics of implied volatility surfaces (IVS) aims at reducing complexity. For this …, neglects the degenerated string structure of the implied volatility data and may result in a severe modelling bias.
