Abstract The analysis of capital injection strategy in the literature of insurance risk models (e.g. Pafumi, 1998; Dickson and Waters, 2004) typically assumes that whenever the surplus becomes negative, the amount of shortfall is injected so that the company can continue its business forever. Recently, Nie et al. (2011) has proposed an alternative model in which capital is immediately injected to restore the surplus level to a positive level b when the surplus falls between zero and b, and the… 
Delayed Capital Injections for a Risk Process with Markovian Arrivals
In this paper we propose a generalisation to the Markov Arrival Process (MAP) risk model, by allowing for a delayed receipt of required capital injections whenever the surplus of an insurance firm is
A plan of capital injections based on the claims frequency
Abstract In this work, we propose a capital injection strategy which is periodically implemented based on the number of claims in the classical Poisson risk model. Especially, capital injection
Randomized observation periods for compound Poisson risk model with capital injection and barrier dividend
In this paper, we model the insurance company’s surplus by a compound Poisson risk model, where the surplus process can only be observed at random observation times. It is assumed that the insurer
On a Periodic Capital Injection and Barrier Dividend Strategy in the Compound Poisson Risk Model
In this paper, we assume that the reserve level of an insurance company can only be observed at discrete time points, then a new risk model is proposed by introducing a periodic capital injection
Periodic threshold-type dividend strategy in the compound Poisson risk model
ABSTRACT In this paper, the compound Poisson risk model is considered. Inspired by Albrecher, Cheung, & Thonhauser. [(2011b). Randomized observation periods for the compound Poisson risk model:
On a perturbed compound Poisson risk model under a periodic threshold-type dividend strategy
In this paper, we model the insurance company's surplus flow by a perturbed compound Poisson model. Suppose that at a sequence of random time points, the insurance company observes the surplus to
On the improved thinning risk model under a periodic dividend barrier strategy
In this study, we consider a periodic dividend barrier strategy in an improved thinning risk model, which indicates that insurance companies randomly receive premiums and pay dividends. In the
On a dividend problem with random funding
This work considers a modification of the dividend maximization problem from ruin theory and derives an optimal strategy whose nature heavily depends on the size of the transaction costs.


On a Periodic Dividend Barrier Strategy in the Dual Model with Continuous Monitoring of Solvency
We consider the dual model, which is appropriate for modeling the surplus of companies with deterministic expenses and stochastic gains, such as pharmaceutical, petroleum or commission-based
The Markov Additive Risk Process Under an Erlangized Dividend Barrier Strategy
In this paper, we consider a Markov additive insurance risk process under a randomized dividend strategy in the spirit of Albrecher et al. (2011). Decisions on whether to pay dividends are only made
The finite time ruin probability in a risk model with capital injections
We consider a risk model with capital injections. We show that in the Sparre Andersen framework the density of the time to ruin for the model with capital injections can be expressed in terms of the
A unifying approach to the analysis of business with random gains
In this paper, we consider a stochastic model in which a business enterprise is subject to constant rate of expenses over time and gains which are random in both time and amount. Inspired by
Gerber–Shiu analysis of a risk model with capital injections
We consider the risk model with capital injections studied by Nie et al. (Ann Actuar Sci 5:195–209, 2011; Scand Actuar J 2015:301–318, 2015). We construct a Gerber–Shiu function and show that whilst
Lévy insurance risk process with Poissonian taxation
The idea of taxation in risk process was first introduced by Albrecher, H. & Hipp, C. Lundberg’s risk process with tax. Blätter der DGVFM 28(1), 13–28, who suggested that a certain proportion of the
Optimal dividend strategies in a Cramer–Lundberg model with capital injections and administration costs
In this paper, we consider a classical risk model with dividend payments and capital injections in the presence of both fixed and proportionals administration costs. Negative surplus or ruin is not
Minimizing the ruin probability through capital injections
Abstract We consider an insurer who has a fixed amount of funds allocated as the initial surplus for a risk portfolio, so that the probability of ultimate ruin for this portfolio is at a known level.
