摘要: In this talk I discuss aggregation properties for risk measures in use throughout the financial and insurance industry. I present a numerical algorithm for the calculation of (min,max)-bounds for the portfolio risk if only the dsitributions of the marginal risks are known. Model uncerrtainty here refers to uncertainty with respect to the interdependence of the risks. The paper is based on a recently published paper: Embrechts, P., Puccetti, G., Rueschendorf, L (2013): Model uncertainty and VaR aggregation. Journal of Banking and Finance 37(8), 2750-2764, a copy of which is to be found on my website www.math.ethz.ch/~embrechts ([some Selected Papers])
