• TITLE: Being Efficient to Stay Strong in a Weak Economy. The Case of Calabrian Manufacturing Firms

  AUTHORS: Francesco Aiello, Concetta Castiglione

  KEYWORDS: ICT, R&D, Stochastic Frontier, Calabria, Manufacturing Firms

  JOURNAL NAME: Technology and Investment, Vol.5 No.2, May 13, 2014

  ABSTRACT: 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).
