Professor Abbas Valadkhani

Professor, Applied Economics and Finance


Professor Valadkhani graduated from the University of Queensland in 1997. He has held full-time permanent positions at the University of Newcastle, Queensland University of Technology, the University of Wollongong, and the University of New England. His recent research interests lie in energy economics, monetary policy, investment, and quantifying extreme downside risk. His articles have been cited in 44 different A and A* journals. 

In 2016, his research work, published in The Conversation and The Guardian, provided significant policy input for several parliamentarians. This input led to an inquiry into how Australia's 'Big Four' banks set interest rates, which received extensive media coverage. During a Senate Committee inquiry, parliamentarians directly cited his name and findings while questioning the CEOs of the 'Big Four' banks. This citation resulted in increased transparency and competition in the market.

In recognition of the public policy impact of his research into financial institutions, he received the 2015 Vice-Chancellor’s Research Excellence Award at Swinburne University of Technology. His work on the interest-rate setting behavior of the Australian big-four banks was immediately read by federal politicians across the political spectrum. In terms of engagement and impact, The Conversation ranked his article among the top six leading articles in its 2016 Stakeholder Report. He has secured several competitive grants from the ARC (DP120102753, Sole CI), Wollongong City Council and Regional Development Australia, and NSW Environmental Trust.

He has supervised 15 PhD students to successful completion.


As of 3 May 2024, based on the multi-dimensional publication data during the last ten years, he has been ranked in the top 7% of 68,286 registered economists in the world by the RePEc: 

This composite ranking is based on more than 34 different research criteria including bibliographic data and citation analysis.
