Questo articolo propone una descrizione del processo produttivo
che permette di confrontare differenti approcci presenti in
letteratura. L'analisi presentata fa riferimento ad un
campione rappresentativo delle imprese italiane
nel settore manifatturiero. Si impiegano sia metodi
parametrici che non parametrici. Questi ultimi
permettono di individuare un elevato grado di eterogeneità nel
modo in cui è effettuata la produzione da imprese in
uno stesso settore.
I risultati dell'analisi
parametrica evidenziano come i coefficienti
stimati siano poco sensibili alla scelta del modello.
This paper provides a description of the production process
by comparing different frameworks in which to analyze
the relations between inputs and output. The analyses
are performed on a representative sample of Italian
manufacturing firms. We employ both parametric and non-parametric
analysis. The latter allows to detect the presence
of heterogeneity in the way the production is carried out
within each sector.
Results of the parametric analysis
show that coefficient estimates tend to be robust with
respect to the different models em ployed. [JEL Code:
