Stochastic optimal switching model for migrating population dynamics

“…supporting (28). The result (34) implies that (28) may not work effectively if we want to distinguish the cases 0 < R < 1 and R = 1, but has no problem if we focus on whether R > 1 or not, which is the case often encountered in biological modelling.…”

“…In general, an SDP problem is a maximization, minimization, or a saddle-point problem of an objective function subject to system dynamics to be optimized. In an engineering SDP problem, the decision-maker is human as an inspector of a system as widely seen in problems of manufacturing [23,24], economics [25,26], insurance [27,28], resource management [29,30], ecological management [31,32], and environmental management [33,34]. On the other hand, the decision-maker in a problem of population dynamics is the population themselves [21,22].…”

The impact of war on insurer safety: a contingent claim model analysis

“…There are several compelling reasons for focusing on insurer safety during times of war. Firstly, the probability of insurer insolvency and the level of policyholder protection, encapsulated by insurer safety, significantly influence strategic decisions made by insurers and are of utmost concern to regulators striving to uphold insurance stability (e.g., Xu et al 2017, in financial investment; Xue et al 2019, in derivatives trading; Chi and Liu 2021, in reinsurance and external finance; Gizzi et al 2020, in earthquake under insurance). Secondly, insurers often evaluate their performance relative to their peers based on safety considerations (Gatzert 2008).…”
