This course covers advanced concepts in antitrust law and competition policy, focusing in particular on how Internet platforms (such as Amazon and Uber) challenge existing doctrines such as monopolization, abuse of dominance, and market definition. The course revolves around American and European Union laws, which have struggled to balance innovation against competition and consumer welfare under their old paradigms. To round out its analyses, this course will introduce basic economic theories such as leveraging, foreclosure, and network effects to show how economic realities can influence the evolution of legal doctrine.
