The recent paper by Ling and Tong (2005) considered a quasi-likelihood ratio test for the threshold in moving average models with errors. This article generalizes their results to the case with GARCH errors, and a new quasi-likelihood ratio test is derived. The generalization is not direct since...

In this paper, we consider the classical surplus process with interest and a constant dividend barrier. Under constant interest, we derive an integro-differential equation for the Gerber-Shiu expected discounted penalty function. Following an idea of Lin, Willmot and Drekic [Lin, X.S., Willmot,...

Risk management in a Virtual Enterprise (VE) is an important issue due to its agility and diversity of its members and its distributed characteristics. In this paper, we develop a risk management model for the VE. More specifically, we introduce a Distributed Decision Making (DDM) model for risk...

Modelling dependent defaults has long been a central issue for credit risk measurement and management. To address this important issue, we introduce a Markovian infectious model to describe the dependent relationship of default processes of credit securities. The central tenant of the proposed...

In this article, we consider a model of multiple make-to-order suppliers, which compete based on their promised sojourn times. A fixed penalty is imposed on the suppliers for failing the promised delivery time requirement at an agreed service level. The demand is allocated to the suppliers...

This paper investigates the relationship between firm performance and corporate governance in China. Firm performance is measured by Tobin's Q, while corporate governance is determined based on ownership structure and concentration. Prior research, in both China and elsewhere, indicates that...
