Abstract

The quantification of diversification benefits due to risk aggregation has received more attention in the recent literature. In this paper, we establish second-order expansions of the risk concentration based on the risk measure of conditional tail expectation for a portfolio of n independent and identically distributed loss random variables. The key tools are the theory of second-order regular variation and the theory of second-order subexponentiality. Some examples are given.
