The course introduces monopoly regulation from an economics perspective. It explores critical questions such as: What structural characteristics give rise to a "natural monopoly," necessitating regulatory intervention beyond traditional competition law? What are the principles guiding price regulation (efficient pricing rules with budget constraints, variable demand, multi-product or multi-market firms)? How can regulatory challenges stemming from information asymmetry between regulators and monopolies be effectively addressed? How should access to common essential facilities by competing providers be priced?

The course analyzes a number of case studies, spanning "traditional" public utilities (water and transportation) and "new" sectors such as payment systems and digital platforms regulation.
