    Optimal investment-consumption-insurance with random parameters

    No full text
    This paper discusses an optimal investment, consumption, and life insurance purchase problem for a wage earner in a complete market with Brownian information. Specifically, we assume that the parameters governing the market model and the wage earner, including the interest rate, appreciation rate, volatility, force of mortality, premium-insurance ratio, income and discount rate, are all random processes adapted to the Brownian motion filtration. Our modeling framework is very general, which allows these random parameters to be unbounded, non-Markovian functionals of the underlying Brownian motion. Suppose that the wage earner’s preference is described by a power utility. The wage earner’s problem is then to choose an optimal investment-consumption-insurance strategy so as to maximize the expected, discounted utilities from intertemporal consumption, legacy and terminal wealth over an uncertain lifetime horizon. We use a novel approach, which combines the Hamilton–Jacobi–Bellman equation and backward stochastic differential equation (BSDE) to solve this problem. In general, we give explicit expressions for the optimal investment-consumption-insurance strategy and the value function in terms of the solutions to two BSDEs. To illustrate our results, we provide closed-form solutions to the problem with stochastic income, stochastic mortality, and stochastic appreciation rate, respectively.26 page(s

    Identifying key factors for successful joint venture in China

    China has become one of the top three nations for attracting foreign investment in the international market since 1990. Hundreds of international corporations are currently competing for business opportunities in China in the form of joint venture or direct investment. Both successful joint ventures and failed investments have been reported. Research, addressing issues of the conflicts between different cultures, traditions, as well as value systems, has appeared recently, but few focuses on identifying the key factors and their managerial implications for foreign investors to successfully enter China\u27s market. This paper presents an application of analytic hierarchy process (AHP) in such an effort, through a case study of China Motorola. This study shows that for foreign investors, by identifying key success factors and then incorporating those factors into firm\u27s long-term business strategies and policies can enhance their business opportunities in China for a long time to come, even under China\u27s current complex economic and marketing conditions

    In this paper, the implementation process of the system of ISO 9000 standards is investigated and the importance of the ISO 9000 standards is then assessed through a specific case study - English China Clays International (ECCI), located in middle Georgia. To be competitive in today\u27s marketplace, ECCI doesn\u27t have any reason to hesitate or prolong becoming certified, as such a certification has become a required condition to sell their products in Europe. Certification forced ECCI to keep detailed records and enabled them to analyze important performance measures. Additionally, the company is convinced that their certification has made the company be more cost effective, maintaining a higher market share, realizing a 10% increase in export, and reducing cost per ton by 7%. In summary, the certification has proven to be significantly contributive to the success of the company in their global market competition. [PUBLICATION ABSTRACT
