This paper considers railway operations in 23 European countries during 1995-2001, where a series of reform initiatives were launched by the European Commission, and analyses whether these reform initiatives improved the operating efficiency of the railways. Efficiency is measured using...

The increasing serial cost sharing rule of Moulin and Shenker [Econometrica 60 (1992) 1009] and the decreasing serial rule of de Frutos [Journal of Economic Theory 79 (1998) 245] have attracted attention due to their intuitive appeal and striking incentive properties. An axiomatic...

Several axioms have been proposed for the axiomatization of input measures of technical efficiency. In this paper our primary concern is the Färe-Lovell efficiency measure. It is shown that this measure can be characterized by a set of five independent axioms.

This paper suggests a simple approximation procedure for the assessment of productivity scores with respect to fuzzy production plans. The procedure has a clear economic interpretation and all the necessary calculations can be performed in a spreadsheet making it highly operational.

Measures of health status, such as e.g. the QALY (Quality Adjusted Life Years) measure, have been proposed as a tool in the economic assessment of new medical technologies, and its possible foundations in individual utility theory have been discussed in the literature. However, the problems of...

This paper considers allocation rules. First, we demonstrate that costs allocated by the Aumann-Shapley and the Friedman-Moulin cost allocation rules are easy to determine in practice using convex envelopment of registered cost data and parametric programming. Second, from the linear programming...

This paper considers generalized Lorenz-maximal solutions in the core of a convex TU-game and demonsrtates that such solutions satisfy coalitional monotonicity and population monotonicity.

A medical internship is mandatory for all medical students graduating from a Danish university. The internships are distributed fairly even amongst most Danish hospitals, m.a. in order to secure a steady inflow of new doctors to all regions of Denmark. When allocating the graduates to an...

This paper considers the set of Lorenz-maximal imputations in the core of a balanced cooperative game as a solution concept. It is shown that the Lorenz-solution concept satisfies a number of suitable properties such as desirability, continuity and the reduced game property. Moreover, the paper...

The purpose of this paper is to model the multi-criteria decision problem of identifying the most suitable facility locations for biogas plants under an integrated decision support methodology. Here the Geographical Information System (GIS) is used for measuring the attributes of the...
