M Michaelsen, A Szimayer - Quantitative Finance, 2018 - Taylor & Francis
We present an approach for modelling dependencies in exponential Lévy market models
with arbitrary margins originated from time changed Brownian motions. Using weak …

GARCH modelling in continuous time for irregularly spaced time series data

RA Maller, G Müller, A Szimayer - 2008 - projecteuclid.org
The discrete-time GARCH methodology which has had such a profound influence on the
modelling of heteroscedasticity in time series is intuitively well motivated in capturing many ‘…

Nonlinear term structure dependence: Copula functions, empirics, and risk implications

M Junker, A Szimayer, N Wagner - Journal of Banking & Finance, 2006 - Elsevier
This paper documents nonlinear cross-sectional dependence in the term structure of US-Treasury
yields and points out risk management implications. The analysis is based on a …

The uncertain mortality intensity framework: Pricing and hedging unit-linked life insurance contracts

J Li, A Szimayer - Insurance: Mathematics and Economics, 2011 - Elsevier
We study the valuation and hedging of unit-linked life insurance contracts in a setting where
mortality intensity is governed by a stochastic process. We focus on model risk arising from …
