Economie di scala e dimensione ottimale nella distribuzione del gas: una meta-analisi


  • Francesco Gullì


Questo articolo analizza la letteratura sulle economie di scala nelle industrie di distribuzione del gas e dell’elettricità. In particolare viene costruita una meta-analisi che consente di stimare la probabilità che vi siano o meno rendimenti di scala crescenti. Il lavoro mette in luce che le economie di scala nella distribuzione del gas sono relativamente deboli. Esiste una probabilità del solo 15% che si abbiano economie di scala significative. Inoltre si evidenzia come la scala ottimale delle imprese si attesti su valori relativamente bassi, circa 50.000 utenti.
