Abstract

In this paper we consider the product of two positive independent risks Y1 and Y2. If Y1 is bounded and Y2 has distribution in the Gumbel max-domain of attraction with some auxiliary function which is regularly varying at infinity, then we show that Y1Y2 has also distribution in the Gumbel max-domain of attraction. Additionally, if both Y1,Y2 have log-Weibullian or Weibullian tail behavior, we show that Y1Y2 has log-Weibullian or Weibullian asymptotic tail behavior, respectively. We present two applications of our results.
