On conditional Chisini means and risk measures

نویسندگان

چکیده

Given a real valued functional T on the space of bounded random variables, we investigate problem existence conditional version nonlinear means. We follow seminal idea by Chisini (1929), defining mean as solution equation induced T. provide sufficient conditions which guarantee (unique) system infinitely many equations, will so-called Conditional mean. apply our findings in characterizing scalarization Risk Measures, an essential tool originally adopted Detlefsen and Scandolo (2005) to deduce robust dual representation.

Conditional and dynamic convex risk measures

We extend the definition of a convex risk measure to a conditional framework where additional information is available. We characterize these risk measures through the associated acceptance sets and prove a representation result in terms of conditional expectations. As an example we consider the class of conditional entropic risk measures. A new regularity property of conditional risk measures ...

On a Chisini Conjecture

Chisini's conjecture asserts that for a cuspidal curve B ⊂ P 2 a generic morphism f of a smooth projective surface onto P 2 of degree ≥ 5, branched along B, is unique up to isomorphism. We prove that if deg f is greater than the value of some function depending on the degree, genus, and number of cusps of B, then the Chisini conjecture holds for B. This inequality holds for many different gener...

Optimal Portfolio Selection for Tehran Stock Exchange Using Conditional, Partitioned and Worst-case Value at Risk Measures

This paper presents an optimal portfolio selection approach based on value at risk (VaR), conditional value at risk (CVaR), worst-case value at risk (WVaR) and partitioned value at risk (PVaR) measures as well as calculating these risk measures. Mathematical solution methods for solving these optimization problems are inadequate and very complex for a portfolio with high number of assets. For t...

Compositions of Conditional Risk Measures and Solvency Capital

Abstract: In this paper, we consider compositions of conditional risk measures in order to obtain time-consistent dynamic risk measures and determine the solvency capital of a life insurer selling pension liabilities or a pension fund with a single cash-flow at maturity. We first recall the notion of conditional, dynamic and time-consistent risk measures. We link the latter with its iterated pr...
