Measuring and comparing the performances of energy retail companies: Firm strategies following the liberalization

In the last decade, the Italian natural gas market has undergone profound changes. The slow ongoing process of liberalization that began in 2000 has produced many changes in the industry as companies have had to react to the new regulatory framework. Many companies have sought agreements, alliances and mergers to consolidate their position in the market, other companies have sought to diversify their product range by becoming multi-utility companies, others, unable to react to the new competitive pressures, have gone bankrupt. The aim of the work is to analyse the performance of natural gas retail companies after the liberalization of the sector.
