本文用数值分析的方法分析了在非期望效用函数下的投资决策问题.文章在模型和均衡分析的基础上指出,政府开支的增加,提高了代理人的风险投资,而政府税收的提高减少了风险投资.在数值分析中详细地分析了跨时替代弹性和相对风险厌恶系数彼此独立变化时,风险投资的变化情况,比较了风险投资受税收和风险的影响在非期望效用函数和期望效用函数下的差异,指出了期望效用函数对风险投资分析具有不确切性. 相似文献

针对已有的随机泛函微分系统的渐近稳定性的结果,要求系统的系数满足线性增长条件,本文主要目的是去掉这一限制条件,给出了非线性随机泛函微分系统的渐近稳定性的新结果.新的稳定性判据不仅可以涵盖更多的非线性随机泛函微分系统,而且证明方法更加简单. 相似文献

By using EDTA-lanthanide (Eu3+, Tb3+) coordination compound as precursor, multicolor luminescent SiO2 nanoshperes were prepared. Also, without any pre-treatment to the surface of SiO2 nanosphere, a facile strategy was developed for the synthesis of SiO2@Au core-shell nanospheres. 相似文献

CdS microspheres were prepared by a hydrothermal microemulsion method in cyclohexane/Triton X-100/pentanol/water at 180℃. The as-prepared samples were characterized by X-ray diffraction analysis, transmission electron microscopy, electron diffraction, energy diffraction X-ray analysis and photoluminescence spectra. It was found that CdS microspheres with diameter of 1.5-2.5μm were aggregated by nanocrystals. The formation mechanism was proposed. 相似文献

Low-dimensional CuI nanomaterials were synthesized in microemulsions containing cyclohexane, Triton X-100, n-pentanol and aqueous solution. The redox reaction took place in this system and the final products CuI were obtained. It′s found that the morphology of CuI could be influenced a great deal by the experimental param-eters such as w0 (the molar ratio of water to surfactant), reactant concentration and the aging time. Hexagonal or shuttle-like CuI flakes, nanoparticles and nanofibers could be prepared respectively under certain conditions. 相似文献
