Mixed fractional risk process [PDF]
In this paper, we introduce a risk process, namely, the mixed fractional risk process (MFRP) in which the number of claims in the associated claim process are modelled using the mixed fractional Poisson process (MFPP). The covariance structure of the MFRP is studied and its long-range dependence property has been established.

Classifying Insurance Reserve Period via Claim Frequency Domain Using Hawkes Process
In this paper, the insurance reserve period will be classified according to the claim frequency domain, such as high- or low-frequency periods. We use the clustering method to create and group claims data according to their frequency period.

Merton Investment Problems in Finance and Insurance for the Hawkes-Based Models
We show how to solve Merton optimal investment stochastic control problem for Hawkes-based models in finance and insurance (Propositions 1 and 2), i.e., for a wealth portfolio X(t) consisting of a bond and a stock price described by general compound ...

Neural Processing of Risk [PDF]
In our everyday life, we often have to make decisions with risky consequences, such as choosing a restaurant for dinner or choosing a form of retirement saving. To date, however, little is known about how the brain processes risk. Recent conceptualizations of risky decision making highlight that it is generally associated with emotions but do not ...

Compound Power Series Distribution with Negative Multinomial Summands
The paper considers a multivariate distribution whose coordinates are compounds. The number of the summands is itself also a multivariate compound with one and the same univariate Power series distributed number of summands and negative multinomially ...

Asymptotic Expected Utility of Dividend Payments in a Classical Collective Risk Process
We find the asymptotics of the value function maximizing the expected utility of discounted dividend payments of an insurance company whose reserves are modeled as a classical Cramér risk process, with exponentially distributed claims, when the initial ...

Influence mechanism of congestion degree of layout on domino effect in petrochemical plants [PDF]
The study focused on the establishment of the congestion degree in describing the layout of process plants, and discovering the influence mechanism of congestion degree on the risk of domino effect, in view of the fact that the congestion degree has not ...

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