Beyond cash-additive risk measures: when changing the numéraire fails

W Farkas, P Koch-Medina, C Munari - Finance and Stochastics, 2014 - Springer
We discuss risk measures representing the minimum amount of capital a financial institution
needs to raise and invest in a pre-specified eligible asset to ensure it is adequately …

Lipschitz properties of the scalarization function and applications

C Tammer, C Zălinescu - Optimization, 2010 - Taylor & Francis
The scalarization functions were used in vector optimization for a long period. Similar
functions were introduced and used in economics under the name of shortage function or in …

Multivariate risks and depth-trimmed regions

I Cascos, I Molchanov - Finance and stochastics, 2007 - Springer
We describe a general framework for measuring risks, where the risk measure takes values
in an abstract cone. It is shown that this approach naturally includes the classical risk …

A Benson-type algorithm for bounded convex vector optimization problems with vertex selection

D Dörfler, A Löhne, C Schneider… - … Methods and Software, 2022 - Taylor & Francis
We present an algorithm for approximately solving bounded convex vector optimization
problems. The algorithm provides both an outer and an inner polyhedral approximation of …

Variable ordering structures in vector optimization

G Eichfelder - Recent Developments in Vector Optimization, 2011 - Springer
In vector optimization one assumes in general that a partial ordering is given by some
nontrivial convex cone K in the considered space Y. But already in 1974 in one of the first …
