W niniejszej pracy rozważamy problem maksymalizacji oczekiwanej zdyskontowanej użyteczności wypłat dywidend przez firmę ubezpieczeniową, której rezerwy modelowane są przez klasyczny proces Cramera-Lundberga. Na wstępie analizujemy sytuację, gdy wielkość szkód opisana jest rozkładem...

We consider the problem of maximizing the expected utility of discounted dividend payments of an insurance company whose reserves are modeled as a Cram\'er risk process with Erlang claims. We focus on the exponential claims and power and logarithmic utility functions. Finally we also analyze...

In this paper we develop a symbolic technique to obtain asymptotic expressions for ruin probabilities and discounted penalty functions in renewal insurance risk models when the premium income depends on the present surplus of the insurance portfolio. The analysis is based on boundary problems...

We introduce an algebraic operator framework to study discounted penalty functions in renewal risk models. For inter-arrival and claim size distributions with rational Laplace transform, the usual integral equation is transformed into a boundary value problem, which is solved by symbolic...

We consider a renewal jump–diffusion process, more specifically a renewal insurance risk model with investments in a stock whose price is modeled by a geometric Brownian motion. Using Laplace transforms and regular variation theory, we introduce a transparent and unifying analytic method for...

We show that a simple mixing idea allows to establish a number of explicit formulas for ruin probabilities and related quantities in collective risk models with dependence among claim sizes and among claim inter-occurrence times. Examples include compound Poisson risk models with completely...

In this paper we discuss the link between Archimedean copulas and L1 Dirichlet distributions for both finite and infinite dimensions. With motivation from the recent papers Weng et al. (2009) and Albrecher et al. (2011) we apply our results to certain ruin problems.
