Return based risk measures for non-normally distributed returns : an alternative modelling approach
Samunderu, Eyden; Murahwa, Yvonne T. - In: Journal of risk and financial management : JRFM 14 (2021) 11, pp. 1-48
Developments in the world of finance have led the authors to assess the adequacy of using the normal distribution assumptions alone in measuring risk. Cushioning against risk has always created a plethora of complexities and challenges; hence, this paper attempts to analyse statistical...

The risk measurement under the variance-gamma process with drift switching
Ivanov, Roman V. - In: Journal of risk and financial management : JRFM 15 (2022) 1, pp. 1-27
The paper discusses an extension of the variance-gamma process with stochastic linear drift coefficient. It is assumed that the linear drift coefficient may switch to a different value at the exponentially distributed time. The size of the drift jump is supposed to have a multinomial...

Diversification can control probability of default or risk, but not both
Cadenas, Pedro; Gzyl, Henryk - In: Journal of risk and financial management : JRFM 14 (2021) 2/73, pp. 1-10
One of the controversies of diversification is that it may not be beneficial to banks, as it tends to increase systemic risk. Recent theoretical and empirical work have addressed this problem. We argue, from a theoretical perspective, that this controversy ultimately depends on how risk is...
