Dr. Stephen Y CHIU received his undergraduate education in Physics at the Hong Kong Baptist College, and graduate education in Economics at the Pennsylvania State University, where he obtained his Ph.D. degree in 1995. He had since taught at The Chinese University of Hong Kong until he joined The University of Hong Kong in 2002. He has been the principal investigator of seven competitive earmarked grants, and was a Research Fellow in the Hong Kong Institute of Monetary Research during the summer of 2001.
Steve is a theorist and has written papers in different areas of Economics. He likes models in which decision makers have non-negligible effects on the environment where they situate. He has published a few papers on bargaining. In one paper, the widely used solution concept Shapley value is implemented as the unique outcome in a non-cooperative game under the least restrictive conditions. Two other papers clear up the profession’s confusion on two concepts in bargaining theory — threat point and outside option, providing important insights into the implications of the now influential property rights approach of firm theory. He has also written papers on the micro-foundations of currency crisis, examining the issue of multiple equilibria in more realistic models of currency attacks. More recently, he has worked on problems such as contract design, college admissions, and demography and political economy of reform, motivated by a contrast between China and Russia in their demography and reform experience.
For leisure, Steve enjoys hiking, reading and tai chi.

人类社会正处于十九世纪以来的第三次能源转型。第一次能源转型,是指植物能转为燃煤发电;第二次是指以化石燃料取代煤炭;至于目前的第三次转型,是指以可再生的洁净能源,来取代污染性较高的化石能源,使其成为人类社会的主要能源。

过去一年,油价升势不止。继欧洲联盟委员会于3月8日建议各国政府可就能源企业的收入进行征税后,美国国会上月推动对石油巨企开征「石油暴利税」(Big Oil Windfall Profits Tax),总统经济顾问Bharat Ramamurti提出应考虑征收此税的建议,拜登更公开批评埃克森美孚「今年赚钱多过上帝」(made more money than God this year)。

专家普遍认为,现时的气候危机在很大程度上是工业革命的后遗症。工业生产会排放大量温室气体暖化地球,如果我们未能将升温幅度控制在不高于工业革命以前1.5至2摄氏度之内,地球很可能在2100年就不宜人类居住。为此,我们必须在2050年以前将全球碳排放降回至2005年的水平。
