Portfolio optimization based on divergence measures

Chalabi, Yohan; Wuertz, Diethelm - Volkswirtschaftliche Fakultät, … - 2012

A new portfolio selection framework is introduced where the investor seeks the allocation that is as close as possible to his "ideal" portfolio. To build such a portfolio selection framework, the f-divergence measure from information theory is used. There are many advantages to using the...

Generalized marginal rate of substitution in multiconstraint consumer's problems and their reciprocal expenditure problems

Besada, Manuel; García, Javier; Mirás, Miguel; … - In: SERIEs - Journal of the Spanish Economic Association 2 (2011) 3, pp. 401-421

The aim of this paper is to explore several features concerning the generalized marginal rate of substitution (GMRS)when the consumers utility maximization problem with several constraints is formulated as a quasi-concave programming problem. We show that a point satisfying the first order...
