The mean-variance investment problem in a constrained financial market

This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time.     

公司财务控制机理:一个基于制度博弈的分析

财务控制的目标是对出资者和经营者之间形成的代理契约的冲突进行管理和协调.以出资者与经营者的制度博弈模型为分析基础,可以清楚表明财务控制机理特征:首先,财务控制本身具有的制度成本(控制成本)是制约控制成效的关键因素;其次,财务控制作为一种制度安排,应具备使经营者违背代理契约的外部成本内部化的功能;最后,财务控制本质是一种契约安排,是出资者和经营者之间多次动态博弈的结果,因此需要不断进行修正完善.     

Are recent segment disclosures of Japanese firms useful?: Views of Japanese financial analysts

Since 1990, the Japanese Ministry of Finance (MOF) has required Japanese firms to disclose segment data in annual financial statements. Using a survey instrument, we examine whether Japanese analysts find these segment disclosures to be useful. Our study finds that analysts perceive that segment data aid them in forecasting consolidated sales and net income. However, results also show that analysts are concerned that Japanese firms do not define segments meaningfully and consistently and are arbitrary in the allocation of common costs. Further, the analysts do not believe that the usefulness of segment data improves when it is audited. These results have implications for investors in Japanese stocks and accounting policy bodies, such as the US Securities and Exchange Commission (SEC).
