On the Distribution of the Surplus Prior and at Ruin

On the Distribution of the Surplus Prior and at Ruin

Consider a classical compound Poisson model. The safety loading can be positive, negative or zero. Explicit expressions for the distributions of the surplus prior and at ruin are given in terms of the ruin probability. Moreover, the asymptotic behaviour of these distributions as the initial capital tends to infinity are obtained. In particular, for positive safety loading the Cramer case, the c...

The surplus prior to ruin and the deficit at ruin for a correlated risk process

This paper presents an explicit characterization for the joint probability density function of the surplus immediately prior to ruin and the deficit at ruin for a general risk process, which includes the Sparre-Andersen risk model with phase-type inter-claim times and claim sizes. The model can also accommodate a Markovian arrival process which enables claim sizes to be correlated with the inte...

مازاد سرمایه در زمان ورشکستگی در مدل ریسک کلاسیک با عامل اغتشاش on the surplus prior to ruin in the perturbed classical risk process

هدف این تحقیق در نظر گرفتن مدل ریسک کلاسیک که با عامل فرآیند وینر ، به مدل ریسک کلاسیک با عامل اغتشاش تبدیل می شود. در این تحقیق فرمول هایی صریح برای تابع چگالی احتمال توام و حاشیه ای مقدار مازاد سرمایه بلافاصله قبل و در زمان ورشکستگی و همچنین تابع چگالی احتمالی برای مقادیر و اندازه خسارت هایی که باعث ورشکستگی شده اند، بررسی می شود. نیاز برای چنین تحقیقی بدین سبب احساس می شود که در مدل ریسک کل...

on translation of phatic communion and socio-cultural relationships between the characters of the novels

phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
