A very good choice in my opinion. Though in some ways a pity it was not on a joint ticket with Tony Atkinson.
Here is link to his personal web page http://scholar.princeton.edu/deaton/home.
Deaton has written extensively on consumer demand systems, taxation, health, welfare, poverty, well-being, econometric methodology, the list is very long.
There is a good discussion of his contributions at http://marginalrevolution.com/marginalrevolution/2015/10/nobel-prize-winner-is-angus-deaton.html and http://marginalrevolution.com/marginalrevolution/2015/10/deaton.html.
Note that Deaton is due to speak in Ireland soon, along with our own Cormac O Grada on the topic of “Modern Plagues: Lessons Learned from the Ebola Crisis”.
