Reinsurance Policy under Interest Force and Bankruptcy Prohibition

Continuous-time Mean-variance Portfolio Selection with Bankruptcy Prohibition

A continuous-time mean-variance portfolio selection problem is studied where all the market coefficients are random and the wealth process under any admissible trading strategy is not allowed to be below zero at any time. The trading strategy under consideration is defined in terms of the dollar amounts, rather than the proportions of wealth, allocated in individual stocks. The problem is compl...

Ruin under interest force and subexponential claims: a simple treatment

A simple proof of the asymptotic formula for the ruin probability of a risk process with a positive constant interest force [derived earlier by Asmussen (Asmussen, S., 1998. The Annals of Applied Probability 8, 354–374)] is given. The proof is based on a formula obtained by Sundt and Teugels (Sundt, B., Teugels, J.L., 1995. Insurance: Mathematics and Economics 16, 7–22). © 2000 Elsevier Science...

Optimizing Consumer Credit Markets and Bankruptcy Policy

This Article explores the relationship between consumer credit markets and bankruptcy policy. In general, I argue that the causative relationships running between borrowing and bankruptcy compel a new strategy for policing the conduct of lenders and borrowers in modern consumer credit markets. The strategy must be sensitive to the role of the credit card in lending markets and must recognize th...

Two - sided Bounds for Ruin Probability under Constant Interest Force

In this paper we investigate the ruin probability in the classical risk model under a positive constant interest force. We restrict ourselves to the case where the claim size is heavy-tailed, i.e. the equilibrium distribution function (e.d.f.) of the claim size belongs to a wide subclass (denoted A) of subexponential distributions. Two-sided estimates for the ruin probability are developed by r...
