Title:

Tecnologia e produttività delle aziende elettriche municipalizzate (Technology and productivity in italian electric municipal firms)

Description:

WP 08/1997; This paper analyses the technological characteristics of a sample of Italian electric municipal firms. The standard partial productivity approach is integrated with total factor productivity measures based on Data Envelopment Analysis. Main results can be summarised as follows: i) small firms are often located on the efficiency frontier, this in turn pointing out that technological economies of scale do not seem very important in this industry, ii) the presence of economies of density is confirmed, iii) vertical integrated firms show better productivity performances. Also, according to Malmquist index all firms have experienced technological progress over time and this is particularly true for small firms. Summarising, from a purely technological point of view, small integrated firms seem to be the most efficient organizational structure in this industry.
