The Final Report from the ACCC’s Adtech Inquiry: Australian outcomes and global implications




The Australian Competition and Consumer Commission (ACCC) has recently completed an in-depth 18 month inquiry into Australia’s digital advertising technology (adtech) services markets. The final report from that inquiry was publicly released on 28 September 2021. The inquiry examined in detail the intensity of competition in adtech markets, as well as efficiency and transparency issues.  The final report concluded that Google has used its dominant position in the ad tech supply chain in an anti-competitive manner.  The ACCC has recommended that new regulatory solutions are required to restore competition for the benefit of businesses and consumers.

ACCC Chair, Rod Sims, has indicated that in this inquiry, as in the case of other inquiries the ACCC has undertaken regarding digital markets, the ACCC has worked closely with competition regulators internationally.  The final report accordingly highlights issues that concern regulators globally and suggests responses that may be implemented beyond Australia.  The webinar will therefore look not only at the ACCC’s views but will compare global adtech competition developments.

Dina Srinivasan

Dina is a researcher, lawyer, and entrepreneur. She’s also a Fellow with the Thurman Arnold Project at Yale University. Most recently, Ms. Srinivasan’s research and economic analysis of new, tech markets provided the foundation for government enforcement of antitrust laws against two of the largest market cap companies in the world. Her 2020 research, “Why Google Dominates Advertising Markets: Competition Policy Should Lean on the Principles of Financial Market Regulation“, explains how Google distorts electronically traded ad markets by engaging in conduct that lawmakers normally prohibit (e.g., conduct analogous to insider trading and front running). Her research instigated a shift in the House and Senate and a coalition of U.S. States subsequently filed suit against the company relying on the architecture of Ms. Srinivasan’s thinking. “The Antitrust Case Against Facebook”, published in 2019, laid out the correlation between privacy and economics. Congress called on the U.S. Federal Trade Commission to open an investigation; and in 2020, the Federal Trade Commission and a coalition of 48 Attorneys General filed actions against Facebook. She’s been profiled by The New York Times and The Wall Street Journal. Her research and commentary on tech and competition are regularly covered in the domestic and global media. View full profile
