Abstract

This study considers the financial performance of state-owned enterprises (SOEs) in relation to non-commercial goals. We focus on enterprises operating in the production of electricity sector in the EU countries and analyse their profitability conditioning on the level of electricity prices. We reveal that SOEs underperform as compared to their privately owned counterparts when they operate in those markets that have lower prices. This suggests that their profitability is likely to be substantially affected by pursuing goals other than profit-maximisation - providing crucial products and services at affordable prices - and emphasises a need to consider the non-commercial objectives of SOEs in the empirical research.
