Nobody knew how to price volatility until now. I bet you're surprised! 

This isn't hyperbole, Steve Mildenhall and John Major have a deep and thorough understanding of all the relevant literatures and have been part of a loosely collaborative team of academics and actuaries working out the details of a coherent, actionable theoretical foundation for pricing insurance for their entire careers. Now that they're both retired they've delivered us the tome the actuarial profession needs. 

Their new book: *Pricing Insurance Risk: Theory and Practice* is an absolute masterpiece. It is theoretically sound and immensely practical. Until today no financial institution could choose a sophisticated portfolio model that wasn't hiding biases or inefficiencies that had to be 'band-aid-ed' over with coarse heuristics. Very importantly how does one calculate the margin required to service the capital base when the risks vary so much? The science of managing a portfolio of incompletely diversified, highly volatile financial instruments has gained serious ground with this book. 

Steve Mildenhall is head of analytics at Qualrisk, an Insurance consulting firm, formerly assistant professor of actuarial science at St. John's University, and before that CEO of analytics at Aon. This is Steve's fifth appearance on this show. John Major is principal at Major analytics and the former director of actuarial research at guy carpenter.
