Time consistency of multi-period distortion measures

Abstract: Dynamic risk measures play an important role for the acceptance or non-acceptance of risks in a bank portfolio. Dynamic consistency and weaker versions like conditional and sequential consistency guarantee that acceptability decisions remain consistent in time. An important set of static risk measures are so-called distortion measures. We extend these risk measures to a dynamic setting within the framework of the notions of consistency as above. As a prominent example, we present the Tail-Value-at-Risk (TVaR).

“…To price American options with early execution characteristics, a multinomial, dynamic concave distortion measure must be used. Taking into account the temporal consistency of prices, the multiperiod dynamic uniform concave distortion measure given by Fasen and Svejda [4] is used to obtain the price of American options.…”

“…Dilip Madan and Wim Schoutens [3] solved the parameter correction problem of distortion risk measures by using the bid-ask transaction history data in the options market. Fasen and Svejda [4] gave a dynamic consistency version to ensure that acceptability decisions are consistent over time. One of the static risk measures is the so-called distortion measure.…”

“…Exemplos envolvendo distribuições invariantes a localização, escala e formato são apresentadas para ilustrar a abordagem. Fasen & Svejda (2012) estendem o conceito de medidas de risco de distorção para o campo dinâmico. Para tanto, os autores utilizam os conceitos de Roorda & Schumacher (2007) para definições de Consistência Sequencial, Condicional e Dinâmica para medidas de risco de distorção dinâmicas, as utilizando em resultados que ligam axiomas e representação dual.…”
