Dr. Timothy D. HAU obtained his B.A. from Stanford University, and M.A. and Ph.D. in economics from the University of California, Berkeley. Timothy taught at the University of California at Davis before joining The University of Hong Kong. He was an economist at the World Bank and participated in several missions to China, Korea, India and Chile. His World Bank papers on the theory and mechanisms of road use charging have been widely circulated and cited in both the academic and professional literature. Timothy argues that road pricing – in one stroke – saves much wasted travel time and fuel, raises government revenues, as well as improves the environment. Without the differential pricing of road use by time-of-day, road capacity enhancements are self-defeating due to the fundamental law of traffic congestion.
Timothy’s research interest is in internalizing congestion externalities and developing sustainable transportation. His single-authored papers have appeared in journals such as Economica, Economics Letters, Journal of Transport Economics and Policy, Built Environment, Transportation Research and Transportmetrica. As of April 11, 2017, there are altogether 977 citations of his papers listed in Google Scholar Citations. 923 cites, forming the bulk, are based on his single-authored works, whereas 54 citations are credited to joint papers with his coauthors.
As a transportation expert, Timothy was invited to deliver keynote speeches in international conferences held both locally and overseas. Timothy was invited by the World Bank in the nineties to work as an economist in its Transport Division, Infrastructure and Urban Development Department. Subsequently he moved to the Public Economics Division of the World Bank’s Policy Research Department. Altogether he spent four years working as a World Bank Official in Washington D.C. before returning to teach and research at HKU. Timothy has served as an occasional reviewer of manuscripts for the Journal of Economic Literature, Economica, Journal of Transport Economics and Policy, Journal of Public Economics, Hong Kong Economic Papers, The World Bank Economic Review, Canadian Journal of Economics, EASTS Journal, Transportation, International Journal of Sustainable Transportation, Networks and Spatial Economics, and of grant applications for Hong Kong Research Grants Council, University Grants Committee, National Science Foundation of China and Research Grants Council. He was Editorial Advisory Board Member for ITS Journalfrom 1993 to 2001 and also International Editorial Board Member of Transport Policy from 1993 to 2005. He is an Editorial Board Member of Research in Transportation Economics, Elsevier, 2012 to present. He provided policy advice to the Asian Development Bank, United Nations, Inter-American Development Bank, World Bank, National Research Council of the U.S. Academy of Sciences as well as the Central Policy Unit, the Environment, Transport and Works Branch, Transport Department and the Council for Sustainable Development of the HKSAR Government.
Timothy served as Founding Academic Director of the Asia Institute for Political Economy summer academic program from 2002 to 2005. He also helped found the Hong Kong Society for Transportation Studies in 1996, where he is actively serving as a Board Member. He was a Member of the Expert Panel on Sustainable Transport Planning and Central-Wan Chai Bypass for the Harbour-front Enhancement Committee, HKSAR Government in 2005. He continues to serve on over a dozen committees at the University, Faculty and School level. Inter alia, he serves on the Board of Academic Awards, Faculty Scholarship Committee, Faculty Review Committee as well as being the Instructor-in-Charge of Teaching Assistant Appointments and Supervision. He continues to serve on professional bodies in the campus community.
