Arlen primarily researches in the area of competition law, with focus on domestic competition policy reform, the competition law and intellectual property interface and the regulation of newly emerging business models. His publications examine a wide range of fundamental contemporary competition law policy issues and respond not only to international debates but also domestic reform agendas. His work examines the regulation of unilateral conduct, the role of efficiencies in administrative decision making, the regulation of anti-competitive coordinated conduct, the interplay between competition law and intellectual property policies (including parallel import policy and the regulation of anti-competitive conduct engaged in by pharmaceutical companies) as well as the extraterritorial application of Australia's competition laws and the role competition law might play in reducing inequality. More recently, he has focused his attention on whether conventional means of defining markets and analysing the effects of conduct on competition, as well as established policy positions, need to be rethought in light of changes in business models, the emergence of economically powerful digital platform businesses and the increasingly global nature of markets.
Arlen's research interests extend beyond competition law and he has also published articles related to consumer protection.
