飞机颤振模态参数辨识试验的快速滤波算法

在随机双曲折现条件下，显式地给出了具有指数函数（CARA）效用的最优跨期消费与投资组合；在非完备市场下，显式给出了基于CARA效用的收益流的效用无差别价格.结果表明：最优投资比例以及收益流的价值不受随机双曲折现因子的影响；在低折扣阶段，本文的最优消费水平高于Merton模型下的对应值，低折扣时期越短或高低折扣值相差越大，消费差距越明显.     

Moderate discount rates and the competitive case for agroforestry

Various complementary and supplementary relationships between crop components may make agroforestry more valuable than either pure forestry or pure agriculture. However, agroforestry may be beneficial even under purely competitive relationships, provided that the value of growth potential accruing to the forestry component exceeds that accuring to the agricultural component, and the discount factor between beginning and ending of the crop cycle is sufficient to overcome this difference. A simplified model showed significant advantage to agroforestry at a moderate rate of discount. Relaxing the stated simplifying assumptions is unlikely to change this conclusion.
