"Yew-Kwang Ng is one of Australia’s mostimportant and best internationally known economists. In the course of a prolific career dedicated to an economic study of the human condition, Yew-Kwang Ng has made numerous contributions that have had a significant and lasting impact. He has contributed to areas ranging from the economics of happiness to division of labour, and from the environment to the economics of human evolution... In the judgement of the few who may have a claim to represent our profession, Yew-Kwang Ng is ‘one of the leading economic theorists of his generation’ [according to Nobel Laureate Kenneth Arrow], with a ‘remarkable research record’ [according to Nobel Laureate James Mirrlees], who has made ‘major contributions in theoretical Welfare Economics’ [according to Nobel Laureate James M. Buchanan]."
