Ruin probabilities as functions of the roots of a polynomial

open access: yesModern Stochastics: Theory and Applications, 2023
A new formula for the ultimate ruin probability in the Cramér–Lundberg risk process is provided when the claims are assumed to follow a finite mixture of m Erlang distributions.

Ruin probability for renewal risk models with neutral net profit condition

open access: yesNonlinear Analysis, 2023
In ruin theory, the net profit condition intuitively means that the sizes of the incurred random claims are on average less than the premiums gained between the successive interoccurrence times.

How Much We Gain by Surplus-Dependent Premiums—Asymptotic Analysis of Ruin Probability

open access: yesRisks, 2021
In this paper, we generate boundary value problems for ruin probabilities of surplus-dependent premium risk processes, under a renewal case scenario, Erlang (2) claim arrivals, and a hypoexponential claims scenario, Erlang (2) claim sizes.

Exact expression of ultimate time survival probability in homogeneous discrete-time risk model

open access: yesAIMS Mathematics, 2023
In this work, we set up the generating function of the ultimate time survival probability $ \varphi(u+1) $, where $ \varphi(u) = \mathbb{P}\left(\sup\limits_{n\geqslant 1}\sum\limits_{i = 1}^{n}\left(X_i- \kappa\right)<u\right), $ $ u\in ...

Reinsurance in the Supplementary Health: A Counterfactual Study on the Impacts of Reinsurance Treaties Adoption by Healthcare Plans Operators in Brazil

open access: yesBBR: Brazilian Business Review, 2021
The sustainability of the Brazilian Supplementary Health System has been frequently debated, since the number of operators has decreased considerably in recent years after bankruptcy records.

From explanation of the past to prediction of the future: A comparative and predictive research design in the Social Sciences

open access: yesSocial Sciences and Humanities Open, 2022
Business and Psychology research (and the Social Sciences, in general) is heavily biased toward explaining the past. The holy grail in such explanation-oriented research is to develop causal theory, and to test this theory with historical data against a ...

Numerical computation of Gerber–Shiu function for insurance surplus process with additional investment

open access: yesInternational Journal of Mathematics for Industry, 2023
This paper studies the Gerber–Shiu function for the insurance surplus process with additional investment under the Bachelier model. The Gerber–Shiu function allows us to study the moments of the time of ruin, which is the first time that the surplus is ...

Gerber–Shiu Function in a Class of Delayed and Perturbed Risk Model with Dependence

open access: yesRisks, 2020
This paper considers the risk model perturbed by a diffusion process with a time delay in the arrival of the first two claims and takes into account dependence between claim amounts and the claim inter-occurrence times.

On the Expected Discounted Penalty Function Using Physics-Informed Neural Network

open access: yesJournal of Mathematics, 2023
We study the expected discounted penalty at ruin under a stochastic discount rate for the compound Poisson risk model with a threshold dividend strategy. The discount rate is modeled by a Poisson process and a standard Brownian motion.
