摘要 现实社会中,人们在追求效益最大化的同时又希望风险最小化,但现有的投资消费模型较少将两者结合考虑。动态随机规划是对投资消费问题进行优化所常用的方法之一,为了计算方便,通常假设投资期间内的市场参数独立于外生因素,这在现实生活中是不合理的。事实上,证券价格的期望收益和方差通常要受到外生因素的影响。本文是假定证券价格遵循着伊藤扩散过程,即其预期收益和方差为外生状态变量的随机函数,以方差为风险测度,对投资消费财富最大化及风险最小化同时进行考虑的交易策略进行研究,并建立多目标模型,对模型进行求解并解的经济含义进行了分析。 It supposes that asset prices evolve through time according to Ito diffusion processes, the expected yield and (variance) are impacted by exogenous states variables. This paper studies dynamic strategies of maximizing the utility of (Consumption) and Investment and minimizing risk. The multi-objective models are established and the solutions are given.
