ACITI spoke to Brendan Pearson, Australia's Ambassador to the OECD until February 2025, about his time representing Australia at the OECD. We canvas what the OECD is and what it does, the OECD's contribution to policy making in Australia and globally and its role in enabling international economic cooperation. We also touch on a recent OECD study - How Governments Back the Largest Manufacturing Firms - and its relevance to Trump Administration trade policies.
