Production and Efficiency in 21 Industrialized Countries from 1966 to 2007 to Analyse the Italy’s Decline: Application of a Stochastic Frontier Model in a Bayesian Approach.
This paper uses a stochastic frontier production model to estimate the technical efficiency of 21 nations among the more industrialized countries in the world for the wide period from 1966 to 2007. A Cobb-Douglas with labour and capital as inputs, GDP as output and efficiency with exponential distribution appears to work good from a statistical point of view. This model is used to estimate in a bayesian approach the efficiency score of these 21 countries. The bayesian way, applied via Gibbs sampling, is here useful to avoid problems about the small number of observations. So, each efficiency score is obtained as mean of 10,000 draws. The results underline a general and progressive efficienc…
The economic impact of the EFF on the competitiveness of Sicilian fish companies
The measure 2.3 of the European Fisheries Fund, in Sicily, claimed investments of fish companies in production capacity expansion and modernization of fish processing. Have these investments been effective in supporting the competitiveness of these companies and have they influenced the economic sustainability of the regional seafood chain? Proposed analysis contributes to this assessment through an exploratory survey and a review of the changes in their business performance.
