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.
