On the ruin probabilities in a discrete time insurance risk process with capital injections and reinsurance

A Bazyari - Sankhya A, 2023 - Springer
The discrete time insurance risk process with a constant interest force is an interesting
stochastic model in risk theory. This paper considers the issue of ruin probabilities of an …

Interplay of insurance and financial risks in a stochastic environment

Q Tang, Y Yang - Scandinavian Actuarial Journal, 2019 - Taylor & Francis
Consider an insurer who makes risky investments and hence faces both insurance and
financial risks. The insurance business is described by a discrete-time risk model modulated …

On asymptotic finite-time ruin probability of a renewal risk model with subexponential main claims and delayed claims

H Yang, J Li - Statistics & Probability Letters, 2019 - Elsevier
This paper considers a non-standard renewal risk model with constant force of interest,
where each main claim may derive a delayed claim occurring after a random period of time …

Multivariate regularly varying insurance and financial risks in multidimensional risk models

M Cheng, DG Konstantinides, D Wang - Journal of Applied …, 2024 - cambridge.org
Multivariate regular variation is a key concept that has been applied in finance, insurance,
and risk management. This paper proposes a new dependence assumption via a framework …

Background risk model in presence of heavy tails under dependence

DG Konstantinides, CD Passalidis - arXiv preprint arXiv:2405.03014, 2024 - arxiv.org
We study the background risk model under a various forms of dependence and some
distribution classes of heavy tails. First, we study the asymptotic behavior of tail expectation …

Interplay of subexponential and dependent insurance and financial risks

Y Chen - Insurance: Mathematics and Economics, 2017 - Elsevier
We are interested in the ruin probability of an insurer who makes risky investments and
hence faces both insurance and financial risks. Assume that the insurance and financial …
