This paper therefore argues that, in line with the European Commission’s goals, market integration at a European Union level should be further fostered in order to complete the creation of a single market. Harmonization of the legal enforcement systems, competition rules, market access conditions and effectiveness of the legal systems are factors that appear better able to guarantee comparable accounting practices across countries. This is a key issue which deserves further scrutiny and discussion not only at an academic but most of all at a policymaking level.
