New ACCC Commissioner Dr Philip Williams AM trades a long history in economics in the private sector and academia for a crucial role with the competition regulator. He joins partner Simon Muys to discuss the history and future of competition law and economics, from misuse of market power to the structure–conduct–performance paradigm. Plus we examine the proposed merger notification thresholds; Disney's in court for unfair contract terms and a sports joint venture; the new anti-siphoning list gets a workout; the CMA investigates Ticketmaster over Oasis tickets; and the long awaited amendments to the Privacy Act finally land. All this and dynamic pricing with co-hosts Moya Dodd and Matt Rubinstein.
