Much of our work involves the preparation of independent expert reports and/or the provision of expert testimony in competition, regulatory or governmental decision-making processes, commercial disputes or legal proceedings.
We also frequently prepare submissions on behalf of clients and provide informal advice over the phone, in person and/or in writing. Our economists may also be available to work on a contractor basis in both Australia and New Zealand. Some examples of our publicly available work are provided below.
