Date : Tags : , , , ,
"We find that depending on the capitalisation of the network, a holding structure can be beneficial as compared to smaller separated entities. In other instances it can be harmful and actually increase contagion. We illustrate our results in a numerical case study and also determine the optimal level of holding support from a regulator perspective."

Ruin Problems in a Discrete Risk Model in a Markovian Environment

Date : Tags : , , , , , ,
"In a 2019 paper, Yang, Zhang and Lan studied a risk model in which claim occurrence and amount are both governed by an underlying Markovian environment process. We find that the derivations of Yang et al are erroneous; subsequently, we analyzed the model correctly using the matrix analytic method."

Stochastic measure distortions induced by quantile processes for risk quantification and valuation

Date : Tags : , , , ,
" The introduced valuation principle relies on stochastic ordering so that the valuation risk-loading, and thus risk premiums, generated by the measure distortion is an ordered parametric family. The quantile processes are generated by a composite map consisting of a distribution and a quantile function."
