We consider a standard two-player all-pay auction with private values, where the valuation for the object is private information to each bidder. The crucial feature is that one bidder is favored by the allocation rule in the sense that he need not bid as much as the other bidder to win the...

This paper provides a theoretical and numerical analysis of robust hedging strategies in diffusion?type models … including stochastic volatility models. A robust hedging strategy avoids any losses as long as the realised volatility stays …

It is well-known that Gaussian hedging strategies are robust in the sense that they always lead to a cost process of … hedging instruments from a given set of traded assets, in particular of zero coupon bonds, is studied. Misspecified hedging …

in discrete time. Therefore, the hedging bias which originates from the effects of time-discretising strategies is … analysed. It turns out that a systematic hedging bias can only be avoided if a discrete-time hedging model is used. It is shown … how the robustness property for convex payoffs is recovered while at the same time the hedging bias is avoided. …

This paper deals with the superhedging of derivatives on incomplete markets, i.e. with portfolio strategies which generate payoffs at least as high as that of a given contingent claim. The simplest solution to this problem is in many cases a static superhedge, i.e. a buy-and-hold strategy...

Let S=(S_t), t=0,1,...,T (T being finite), be an adapted R^d-valued process. Each component process of S might be interpreted as the price process of a certain security. A trading strategy H=(H_t), t= 1,...,T, is a predictable R^d-valued process. A strategy H is called extreme if it represents a...

In this paper, we present a new approach to measure the returns of private equity investments based on a stochastic model of the dynamics of a private equity fund. Our stochastic model of a private equity fund consists of two independent stages: the stochastic model of the capital drawdowns and...

We investigate financial markets under model risk caused by uncertain volatilities. For this purpose we consider a financial market that features volatility uncertainty. To have a mathematical consistent framework we use the notion of G-expectation and its corresponding G-Brownian motion...
