英文摘要:
The literature of heavy tails (typically) starts with a random walk and finds mechanisms that lead to fat tails under aggregation. We follow the inverse route and show how starting with fat tails we get to thin-tails when deriving the probability distribution of the response to a random variable. We introduce a general dose-response curve and argue that the left and right-boundedness or saturation of the response in natural things leads to thin-tails, even when the \"underlying\" random variable at the source of the exposure is fat-tailed.

中文摘要:
关于重尾的文献(通常)从随机游走开始,发现了导致聚集下的厚尾的机制。我们沿着相反的路线,展示了在推导随机变量响应的概率分布时,如何从厚尾开始到薄尾。我们引入了一个一般的剂量-反应曲线,并认为自然事物中反应的左右有界性或饱和会导致细尾,即使暴露源的“潜在”随机变量是厚尾的。
