Under fairly general assumptions requiring neither a differentiable frontier nor a constant-returns-to-scale technology, this paper introduces a new definition of an optimal scale size based on the minimization of unit costs. The corresponding measure, average-cost efficiency, combines scale and...

The paper presents a rigorous frontier-analysis of technical efficiency, returns to scale and the composition of productivity growth of the Italian prison system over the period 2003-2005. The study tries to fill some gaps in the literature on the subject, which mainly suffers from both...
