Polish Competition Law and Enforcement—Lost in Transition offers the first comprehensive analysis of Poland’s competition protection system. It examines competition protection amid Poland's economic transformation, highlighting why economic transition success has diverged from the effectiveness of the competition system. The publication critically assesses Polish competition law and enforcement, from historical, doctrinal, and systemic perspectives. It emphasizes the links among competition policy, enforcement, and legal frameworks, showing their essential, interconnected roles. The study uncovers a paradox: despite modernization efforts, enforcement has declined in quality and intensity, weakening the overall effectiveness of public enforcement at administrative and judicial levels.
