In the literature, two main ratio-based productivity indices have been defined in terms of a primal technology notion. While the Malmquist productivity index has become very popular, it has the problem that it is not always well-defined. By contrast, the less popular Hicks Moorsteen productivity...

Quite a few studies have considered efficiency at the bank branch level by comparing mostly a single branch network, while an abundance of studies have focused on comparing banking institutions. However, to the best of our knowledge no study has ever assessed performance at the level of the...

This contribution provides a way to define and compute a tangency notion of economic capacity based upon the relation between the various directional distance functions and the profit and cost functions using non-parametric technologies. A new result relating profit and cost function-based...

There is a burgeoning literature using non-parametric frontier methods to measure mutual fund performance. These articles measure the relationship between the various characteristics (mainly return information and some costs of ownership) of these specialized financial products to establish a...

The shortage function has been proposed as a tool to gauge portfolio performance in multi-moment portfolio models. An open issue is how the choice of direction vector affects the efficiency measurement and, from a practical point of view, the resulting league tables. This paper illustrates...

Starting from existing static decompositions of overall economic efficiency on non-parametric production and cost frontiers, this paper proposes more comprehensive decompositions including several cost-based notions of capacity utilisation. Furthermore, in case prices are lacking, we develop...

This contribution explores how multi-dimensional lower partial moment portfolio models are different from their bi-criteria counterparts. In particular, the mean semivariance and semi-skewness model that seems little used in practice is contrasted to the rather popular mean semi-variance and...

The main aim of this contribution is to compare existing and newly developed techniques for geometrically representing mean-variance-skewness portfolio frontiers based on the rather widely adapted methodology of polynomial goal programming (PGP) on the one hand and the more recent approach based...
