摘要翻译:
在连续时间完全市场模型中,风险资产价格过程服从具有时变系数和确定性系数的联合几何布朗运动,对不同个体的最优投资组合进行了比较静力学研究。结果表明,间接效用函数继承了冯·诺伊曼-摩根斯坦效用函数的风险厌恶顺序(在阿罗-普拉特意义上),因此,更厌恶风险的代理人将更少的财富(以绝对值计算)投资于风险资产。

英文摘要:
The comparative statics of the optimal portfolios across individuals is carried out for a continuous-time complete market model, where the risky assets price process follows a joint geometric Brownian motion with time-dependent and deterministic coefficients. It turns out that the indirect utility functions inherit the order of risk aversion (in the Arrow-Pratt sense) from the von Neumann-Morgenstern utility functions, and therefore, a more risk-averse agent would invest less wealth (in absolute value) in the risky assets.
