论永续经营的分配性质

On distributional properties of perpetuities

Gerold Alsmeyer, Alex Iksanov, Uwe Roesler

摘要:

本文研究了一类特殊结构的收敛随机序列的概率分布,这种特殊结构被称为永久序列。通过给出一个新的论证,我们证明了这样的分布是纯型的:退化的,绝对连续的,或连续奇异。进一步给出了$p$矩、$p>0$矩和指数矩的有限性的充分必要条件.特别地,提供了矩母函数收敛横坐标的公式。文章最后用实例说明了结果。

英文摘要:

We study probability distributions of convergent random series of a special structure, called perpetuities. By giving a new argument, we prove that such distributions are of pure type: degenerate, absolutely continuous, or continuously singular. We further provide necessary and sufficient criteria for the finiteness of $p$-moments, $p>0$ as well as exponential moments. In particular, a formula for the abscissa of convergence of the moment generating function is provided. The results are illustrated with a number of examples at the end of the article.
