Duality for pathwise superhedging in continuous time

D Bartl, M Kupper, DJ Prömel, L Tangpi - Finance and Stochastics, 2019 - Springer
We provide a model-free pricing–hedging duality in continuous time. For a frictionless
market consisting of dd risky assets with continuous price trajectories, we show that the …

Robust framework for quantifying the value of information in pricing and hedging

A Aksamit, Z Hou, J Obłój - SIAM Journal on Financial Mathematics, 2020 - SIAM
We investigate asymmetry of information in the context of the robust approach to pricing and
hedging of financial derivatives. We consider two agents, one who only observes the stock …

Non-linear affine processes with jumps

F Biagini, G Bollweg, K Oberpriller - arXiv preprint arXiv:2207.03710, 2022 - arxiv.org
We present a probabilistic construction of $\mathbb {R}^ d $-valued non-linear affine
processes with jumps. Given a set $\Theta $ of affine parameters, we define a family of …

Reduced-form framework under model uncertainty

F Biagini, Y Zhang - 2019 - projecteuclid.org
In this paper, we introduce a sublinear conditional expectation with respect to a family of
possibly nondominated probability measures on a progressively enlarged filtration. In this …

The space of outcomes of semi-static trading strategies need not be closed

B Acciaio, M Larsson, W Schachermayer - Finance and Stochastics, 2017 - Springer
Semi-static trading strategies make frequent appearances in mathematical finance, where
dynamic trading in a liquid asset is combined with static buy-and-hold positions in options …

Robust statistical arbitrage strategies

E Lütkebohmert, J Sester - Quantitative Finance, 2021 - Taylor & Francis
We investigate statistical arbitrage strategies when there is ambiguity about the underlying
time-discrete financial model. Pricing measures are assumed to be martingale measures …

Reduced-form framework for multiple ordered default times under model uncertainty

F Biagini, A Mazzon, K Oberpriller - Stochastic Processes and their …, 2023 - Elsevier
In this paper we introduce a sublinear conditional operator with respect to a family of
possibly nondominated probability measures in presence of multiple ordered default times …

Insurance modeling in continuous time

Y Zhang - 2018 - edoc.ub.uni-muenchen.de
In this dissertation we consider the problem of pricing and hedging insurance liabilities, by
extending concepts and methodologies recently introduced in the mathematical literature for …

Aspects of quadratic utility: mean-variance hedging in rough volatility models, and CAPM-type equilibria

DPT Martins - 2023 - research-collection.ethz.ch
The first main topic of this thesis, considered in Chapters I and II, is the study of the mean
variance hedging problem in the rough Heston model. Rough volatility models have become …

Model-independent pricing with insider information: A Skorokhod embedding approach

B Acciaio, AMG Cox, M Huesmann - Advances in Applied Probability, 2021 - cambridge.org
In this paper we consider the pricing and hedging of financial derivatives in a model-
independent setting, for a trader with additional information, or beliefs, on the evolution of …
