On a theorem of Breiman and a class of random difference equations

Research output: Contribution to journal › Article › peer-review

Abstract

We consider the tail behavior of the product of two independent nonnegative random variables X and Y. Breiman (1965) has considered this problem, assuming that X is regularly varying with index ?? and that E\{Y??+??\} {\textless} ??? for some ?? {\textgreater} 0. We investigate when the condition on Y can be weakened and apply our findings to analyze a class of random difference equations.
