Resumen de Uncertainty and regulatory outcome in the Swedish electricity distribution sector

Magnus Söderberg

• Regulatory agencies are potentially influenced by market characteristics and underlying incentives and use simplifying decision rules. When decision uncertainty increases, it is hypothesised that these influences become more apparent. This study investigates civil cases initiated by dissatisfied customers in the Swedish electricity distribution market. The purpose is to determine (1) how regulatory decision uncertainty manifests itself and (2) whether multi-echelon regulatory structure has a structural impact on regulatory outcome. The results indicate that the regulator’s decisions exhibit status quo bias and that large customers are privileged compared to small customers. The court distinguishes itself by favouring large utilities.
