A risk-based risk finance paradigm

We propose an alternative to the conventional risk finance paradigm of enterprise risk management that accounts for not only a loss portfolio’s expected frequency and expected severity, but also its “risk” as captured by an appropriate measure of dispersion/spread. This new paradigm is based upon four distinct properties of a loss portfolio that enhance the benefits of diversification: (1) a high expected frequency; and (2) less-than-perfect positive correlations between individual severities; (3) light-tailed severities; and (4) a predictable (i.e. non-erratic) frequency.
