Health institutions have realized the importance of privacy engineering that focuses on development of guidelines, practices and models for the protection of patients’ privacy. However, due to the intricate healthcare systems with transitive health workflows, the processing of patient information in one setting may be more problematic than that in another. As a solution to this problem, we deco...

The controversy over whether investment-cash flow sensitivity is a good indicator of financing constraints is still unresolved. We tackle it from several different angles and cross-validate our analysis with both balance sheet and qualitative data on self-declared credit rationing and financing constraints. Our qualitative information shows that (self-declared) credit rationing is (weakly) rela...

The discrete-time risk model with correlated classes of business is examined. Two different relations of dependence are considered. The impact of the dependence relation on the finite-time ruin probabilities and on the adjustment coefficient is also studied. Numerical examples are presented. © 2000 Elsevier Science B.V.

In this note we study the optimal dividend problem for a company whose surplus process, in the absence of dividend payments, evolves as a generalized compound Poisson model in which the counting process is a generalized Poisson process. This model includes the classical risk model and the Pólya-Aeppli risk model as special cases. The objective is to find a dividend policy so as to maximize the ...

Abstract. In this paper, we present a review of results for discrete-time risk models, including the compound binomial risk model and some of its extensions. While most theoretical risk models use the concept of time continuity, the practical reality is discrete. For instance, recursive formulas for discretetime models can be obtained without assuming a claim severity distribution and are readi...

This paper presents a new approach for consumer credit scoring, by tailoring a profit-based classification performance measure to credit risk modeling. This performance measure takes into account the expected profits and losses of credit granting and thereby better aligns the model developers’ objectives with those of the lending company. It is based on the Expected Maximum Profit (EMP) measure...

The tail of the distribution of a sum of a random number of independent and identically distributed nonnegative random variables depends on the tails of the number of terms and of the terms themselves. This situation is of interest in the collective risk model, where the total claim size in a portfolio is the sum of a random number of claims. If the tail of the claim number is heavier than the ...

There are two competing paradigms for modeling credit risk: the structural and reduced form models. This paper applies our knowledgeof creditmarket equilibriumto thisdebate.Weshowthat credit markets have asymmetric information in the borrowing and lending relationshipwhich influenceequilibriumprices.

We consider a discrete-time insurance risk model, in which the financial risks constitute a stationary process with finite dimensional distributions of Farlie–Gumbel–Morgenstern type. We obtain an exact asymptotic formula for the ruin probability, reflecting the impact of this kind of association structure among the financial risks. r 2007 Elsevier B.V. All rights reserved.

From the outsourcer’s perspective, the IS outsourcing literature emphasizes the importance of contracts and risk awareness for managing outsourcing ventures. However, there is a lack of proven and tested outsourcing management concepts in theory and practise incorporating contractual designs to effectively counter risk. By extending the risk model of Bahli and Rivard (2001) we investigate the i...
