CURRICULUM VITAE

“To design economic policy that promotes welfare and reduces poverty, we must first understand individual consumption choices,” the award-giving body said in announcing the 2015 Nobel Prize for economics. “More than anyone else, Angus Deaton has enhanced this understanding.”

Deaton helped transform the fields of micro, macro, and development economics by linking studies of individual choices and aggregate outcomes. To do this he considered three central planks of societal economics: how consumers distribute their spending among different goods; how much they spend and how much they save; and how best to measure and analyse welfare and poverty.

In June 1980, Deaton and John Muellbauer published a paper in The American Economic Review entitled ‘An Almost Ideal Demand System’ (AIDS). This relatively simple, yet flexible formula estimates demand for each product based on prices across the board and individual income. It is used by academics and policymakers to calculate how changes to income tax or taxes on certain goods might affect consumption and which groups in society would be most affected.

A decade later, Deaton demonstrated the importance of analysing individual approaches to consumption and investment, based on fluctuations in income. This closer study produced more revealing results than broader population studies, helps explain patterns in the aggregate studies and is now widely used in macroeconomics to explain capital formation and business cycles.

Deaton’s individual approach to household finances can highlight mechanisms of economic and social development such as gender discrimination and how poverty can affect the welfare of a society – for example by comparing income and calorie intake. In doing so, he has exposed difficulties in long-term poverty studies and has transformed the theoretical field of development economics based on aggregate data into an empirical field that can be of practical value when formulating social policy, especially in poorer countries.

Angus Stewart Deaton was born in Edinburgh, Scotland, in October 1945 and received a foundation scholarship to Fettes College. From there he obtained a place at Fitzwilliam College, Cambridge, where he gained his BA, MA and in 1975 his PhD with a thesis examining consumer demand in the UK. The following year Deaton took the post of Professor of Econometrics at the University of Bristol and it was there that he began his best-known work – the 1980 AIDS paper which has been hailed as one of the 20 most important articles published in The American Economic Review.

In 1983 Deaton left Bristol for Princeton University in New Jersey, where he is now Dwight D. Eisenhower Professor of Economics and International Affairs. He is married to American economist and fellow Princeton Professor Anne Case, and has two grown-up children.

The recipient of several awards and honours, Deaton is a Fellow of the Econometric Society (which awarded him the first Frisch Medal in 1978), and a member of the American Philosophical Society and of the National Academy of Sciences. He is a Corresponding Fellow of the British Academy and an Honorary Fellow of the Royal Society of Edinburgh. He was President of the American Economic Association in 2009 and was knighted in 2016.

Despite the grandeur of such accolades, Sir Angus says he is always keen to “get back to work”, which currently involves researching the determinants of health in rich and poor countries, as well as the measurement of poverty. Although global poverty levels are improving, Sir Angus says: “We are not out of the woods,” and pointing to the upward trend in inequality in many countries, he adds: “I do worry about a world in which the rich get to write the rules.”
