In the antitrust sphere, Greg is regularly sought to advise on the competitive effects of proposed merger transactions, and to provide expert testimony in antitrust enforcement proceedings. His evidence has been cited favourably in numerous proceedings before the Federal Court, the Competition Tribunal and in the decisions of Australian and international arbitrators. For many years, Greg has been listed by Who’s Who Legal as one of the world’s leading competition economists. Most recently, Greg was recognised in WWL’s Thought Leaders – Competition 2020 for his contributions to competition economics.
On regulatory matters, Greg has played a substantial role in shaping the development of economic regulatory regimes governing communications, energy, transport and water services infrastructure in Australia and the Asia Pacific region. His clients in this area include governments, regulators, infrastructure service providers and trade associations.
Greg is also the foremost expert in the region on the application of economics to critical questions arising in securities class actions, insider trading and market manipulation. He has filed expert reports in numerous proceedings concerning the adequacy and effect of disclosures in relation to listed and unlisted securities, in both Australia and New Zealand. Greg’s evidence was accepted in the only two wrongful disclosure matters for which final judgment on substantive elements has been delivered by the Federal Court.
