An elementary proof of the dual representation of Expected Shortfall

Martin Herdegen, Cosimo Munari

We provide an elementary proof of the dual representation of Expected Shortfall on the space of integrable random variables over a general probability space. Unlike the results in…

Robust portfolio selection under Recovery Average Value at Risk

Cosimo Munari, Justin Plückebaum, Stefan Weber

We study mean-risk optimal portfolio problems where risk is measured by Recovery Average Value at Risk, a prominent example in the class of recovery risk measures. We establish exi…
