In this note, we point out some errors in Section 3 of our earlier paper “Levy risk model with two-sided jumps and a barrier dividend strategy” published in Insurance: Mathematics and Economics, 50(2): 280-291, 2012. Specifically, we find that the optimal barrier does not depend on initial...

In this paper, we consider a general Levy risk model with two-sided jumps and a constant dividend barrier. We connect the ruin problem of the ex-dividend risk process with the first passage problem of the Levy process reflected at its running maximum. We prove that if the positive jumps of the...

In this paper, we introduce tractable dynamic models for financial variables (such as interest rates, foreign exchange rates, commodity prices, etc.) with capturing both jump risk and boundedness of the price fluctuation in a regulated market. For the jump risk, we use a compound Poisson process...

In this paper, we consider a portfolio optimization problem in a defaultable market. The representative investor dynamically allocates his or her wealth among the following securities: a perpetual defaultable bond, a money market account and a default-free risky asset. The optimal investment and...

An emerging stream of research documents that experience of traumatic events early in a CEO's life influences the firm's investment and financing choices. We extend this research by examining the impact of CEO early-life natural disaster experience on stock price crash risk. Using a longitudinal...
