Yew-Kwang Ng (Simplified Chinese: 黄有光; born 1942 in Malaysia) is a professor of economics at Nanyang Technological University. He has published in a variety of academic disciplines, and is best known for his work in welfare economics.

Education and academic careerEdit

Ng graduated with a Bachelor of Commerce from Nanyang University in 1966 and later a Ph.D. from Sydney University in 1971. He has been a Fellow of the Academy of Social Sciences in Australia since 1981. He held a chair as professor of economics at Monash University between 1985 and 2012 and is now an emeritus professor. As of 2018, Ng holds the Winsemius chair at the Department of Economics at Nanyang Technological University.[1][2]


Ng has written or co-authored more than 30 books and published more than two hundred refereed papers in economics and papers on biology, mathematics, philosophy, cosmology, psychology, and sociology.[1][3] He proposed welfare biology as an academic discipline,[4] stating that this has been his more underestimated contribution.[5] He published his first academic paper in the Journal of Political Economy while he was still an undergraduate student.[6][7]


Ng is renowned for his work in welfare economics and a majority of his academic papers are in this area.[6] He wrote his first book on the topic in 1979, Welfare Economics: Introduction and Development of Basic Concepts.[8] Within welfare economics he is particularly known for his work on the theory of the third best, social choice theory and happiness economics.[6] In many publications he defends a view of utility as being both cardinally measurable and interpersonally comparable.[9]

Ng coined the term 'mesoeconomics' and helped establish the field as a simplified, tractable general-equilibrium analysis with both micro and macro elements.[10] As a method it is used to study the implications of imperfect competition on the macroeconomy. It has been argued that mesoeconomics "typically yields conclusions that are consistently more closely aligned with empirical evidence than any of the competing macroeconomic models."[6]

Ng contributed to the development of the new field of inframarginal economics, which "provides an analytical framework (...) to reconcile the focus of neoclassical economics on distribution with the preoccupations of classical economists (...) regarding the division of labour."[6] He collaborated with Xiaokai Yang on this topic and in 1993 they published the joint book Specialization and Economic Organization: A New Classical Microeconomic Framework, which was said to have "credibly challenged Neoclassical Economics".[6][11]

Moral philosophyEdit

In moral philosophy, Ng advocates for the consequentialist position of hedonistic utilitarianism. He has defended this view in various academic papers, some of which were jointly written with the utilitarian moral philosopher Peter Singer.[12][13] He also argues for this position in his 2000 book Efficiency, Equality, and Public Policy.[14]

Awards and honoursEdit

Ng has received a number of awards in recognition of his work. In 2007 he was made a Distinguished Fellow of the Economic Society of Australia, the highest award that the Society bestows.[15] In the tribute associated with the award he was described as "one of Australia’s most important and best internationally known economists." [6] According to Economics Nobel Laureate Kenneth Arrow, Ng is "one of the leading economic theorists of his generation" and Nobel Laureate James Buchanan credited him to have "made major contributions in theoretical Welfare Economics."[6]

After Ng's retirement from Monash University, he was recognised as a "honorary and adjunct appointment" by the Department of Economics.[16]

Thanks to his early work on animal welfare, global catastrophic risks and the measurement of wellbeing, he is credited with originating many ideas that would later be incorporated into the philosophy of effective altruism.[17]
