Many multicriteria problems in economics and finance require that efficient solutions be found. A recent contribution to production theory established a characterization of efficient points under closedness and free-disposability (Bonnisseau and Crettez in Econ Theory 31(2):213–223, 2007, Theorem 1). However, as will be shown using a number of examples, these results cannot be applied to simple...

This paper is about dotted representations of efficient frontiers. Dotted representations, as in portfolio selection, can often be the most practical way of communicating an efficient frontier. The most popular method is to minimize variance subject to fixed levels of expected ∗Corresponding author [email protected]

We use a unique dataset of Swedish investors with information broken down at the investor level and into various components of wealth, investor income, tax positions and inve...
