Pricing options on trend-stationary currencies: applications to the Chinese yuan
This paper derives a closed-form version of a model with a trend-stationary, stochastic volatility exchange rate, using both a linear and quadratic trend.
Wavelet decomposition and applied portfolio management
In order to separate short-term noise from long-term trends, this paper decomposes financial return series into their time and frequency domains.
Fitting a distribution to value-at-risk and expected shortfall, with an application to covered bonds
This paper suggests simple and intuitive models for covered bonds that allow quantitative assessment of expected loss and the impact of asset encumbrance.
Operational loss with correlated frequency and severity: an analytical approach
To enable autocorrelation in the frequency distribution, this paper proposes a significant generalization of the LDA model that involves treating operational risk as a Lévy jump-diffusion.
A network-based method for visual identification of systemic risks
This paper introduces the topic of network visualization to the journal by proposing the use of a combination of data reduction techniques and overlays that allow detection of large-scale patterns and outlier activity.
