The aim of this
work is to study the efficiency of firms operating in Calabria, a small and
economically-lagging Italian region. The analysis is carried out by estimating
a stochastic production frontier for an unbalanced panel of manufacturing firms
which are observed over the 1998-2006 period. Results show that the efficiency
score is, on average, about 60%. A declining trend is observed over the last
three-year period, 2004-2006. Moreover, efficiency increases with firm age and
when firms export. Inconclusive evidence is found for the role of investments
in ICT and R&D. This is not very surprising given that private effort in
technological activities is extremely low in Calabria (private R&D
intensity was less than 0.075% of regional GDP in 2010).
This paper presents the procedures and the
outcomes of collaborative activities and of peer tutoring carried out by the
students in the teaching of “General Didactics”, held at the University of Roma
Tre, in ay 2012/13.
