Yew-Kwang Ng (Simplified Chinese: 黄有光; born 1942) is an economist at Monash University. He graduated with a Bachelor of Commerce from Nanyang University in 1966 and later a Ph.D. from Sydney University in 1971.
He holds a personal chair at Monash and has been a Fellow of the Academy of Social Sciences in Australia since 1980. He is renowned for his work in welfare economics. He helped establish mesoeconomics as a simplified, tractable general-equilibrium analysis with both micro and macro elements. He proposed welfare biology as a subject. He collaborated with Xiaokai Yang on an inframarginal analysis of division of labour. He has published more than one hundred refereed papers in economics and papers on biology, mathematics, philosophy, psychology, and sociology. He has published a Kungfu novel in Chinese serialized in Nanyang Business Daily (Malaysia) and as a book The Unparalleled Mystery (1994).
Ng has received a number of awards in recognition of his work. He was recently made a Distinguished Fellow of the Economic Society of Australia, the highest award that the Society bestows. In moral philosophy, he is a firm believer in utilitarianism and has provided strong arguments supporting it, including in his Efficiency, Equality, and Public Policy.
