We describe an approach to the evaluation of the moments of the time of ruin in the classical Poisson risk model. The methodology employed involves the expression of these moments in terms of linear combinations of convolutions involving compound negative binomial distributions. We then adapt the results for use in the practically important case involving phase-type claim size distributions. We...

This paper discusses the shape of the stock return distribution using the all shares index of Helsinki Stock Exchange. Non-parametric kernel density estimation and power exponential family of distributions are used to model the shape of the return distribution. The parameters of power exponential distribution are estimated with Bayesian approach. The findings suggest that the shape of the distr...
