We consider a risk model with threshold strategy, where the insurance company pays off a certain percentage of the income as dividend whenever the current surplus is larger than a given threshold. We investigate the ruin time, ruin probability, and the total dividend, using methods and results from queueing theory.

Prognosis of disease progression is necessary for development of individualized treatment, understanding of the disease. Risk modeling is a challenging problem, and too often amount of available relevant observations is not sufficient to build a quality model with traditional approaches. New method Smooth Rank for survival analysis, risk modeling is introduced here. Smooth Rank is robust agains...

This paper presents dynamic portfolio model based on the Merton's optimal investment-consumption model, which combines dynamic synthetic put option using risk-free and risky assets. This paper is extended version of methodological paper published by Yuan Yao (2012). Because of the long history of the development of foreign financial market, with a variety of financial derivatives, the study on ...

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...

Financial risk is an objective phenomenon in economic activities. It has received extensive attention in theoretical and practical fields. For each company and operators in the market economy, the financial risk is an objective existence. The manufacturing industry as a pillar industry of China’s economic development, occupies a large proportion in China’s listed company. However because of the...

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...
