  • PhD Thesis Proposal Defence (Thursday, June 06, 2013)
    Time: 10:00am-10:30am and Room: WSC 248
    Speaker: Chen Yang
    Title: Renewal Dual Risk Models

    Cramer (1955) first introduced the dual risk model to describe a life-annuity insurance from the perspective of the collective-risk theory. In recent years, the dual risk model is used to capture the behaviour of the surplus of certain type of companies. Many articles consider ruin-related quantities under the compound Poisson dual risk model. Our research aims to extend the existing results under the latter model to the renewal dual risk model.

    Like many other sources in ruin theory, this thesis proposal will focus on two crucial risk measures: the expected discounted dividend paid before the occurrence of ruin and the probability of the ultimate ruin. The approach utilized is to derive an integro-differential equation involving the ruin quantities and then obtain a solution under certain boundary conditions.
