This text deals in detail with the effect of competition law in Ireland, and also within the wider context of the EC. Amongst the topics addressed are anti-competitive arrangements; abuse of the dominant position; and specific arrangements and practices such as cartels, agency, mergers and acquisitions, joint ventures, trade associations, intellectual property agreements, franchising, pricing, trading conditions and advertising. The role of the state and of public authorities are also discussed, along with a complete section on practice and procedure. This book should be a useful aid for practitioners, businesses and students.
