Abstract

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.
