The 2015 Economics "Nobel": Angus Deaton Angus Deaton is only the sixth economist to not share the "Economics Nobel" (the "Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel") in the last 20 years (i.e. from 1996 onwards). 

The Press Release reads:


  Press Release
  
  13 October 2015
  
  The Royal Swedish Academy of Sciences has decided to award The
  Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel
  for 2015 to
  
  Angus Deaton, Princeton University, NJ, USA
  
  "for his analysis of consumption, poverty, and welfare".
  
  Consumption, great and small
  
  To design economic policy that promotes welfare and reduces poverty,
  we must first understand individual consumption choices. More than
  anyone else, Angus Deaton has enhanced this understanding. By linking
  detailed individual choices and aggregate outcomes, his research has
  helped transform the fields of microeconomics, macroeconomics, and
  development economics.
  
  The work for which Deaton is now being honored revolves around three
  central questions:
  
  How do consumers distribute their spending among different goods?
  Answering this question is not only necessary for explaining and
  forecasting actual consumption patterns, but also crucial in
  evaluating how policy reforms, like changes in consumption taxes,
  affect the welfare of different groups. In his early work around 1980,
  Deaton developed the Almost Ideal Demand System – a flexible, yet
  simple, way of estimating how the demand for each good depends on the
  prices of all goods and on individual incomes. His approach and its
  later modifications are now standard tools, both in academia and in
  practical policy evaluation.
  
  How much of society's income is spent and how much is saved? To
  explain capital formation and the magnitudes of business cycles, it is
  necessary to understand the interplay between income and consumption
  over time. In a few papers around 1990, Deaton showed that the
  prevailing consumption theory could not explain the actual
  relationships if the starting point was aggregate income and
  consumption. Instead, one should sum up how individuals adapt their
  own consumption to their individual income, which fluctuates in a very
  different way to aggregate income. This research clearly demonstrated
  why the analysis of individual data is key to untangling the patterns
  we see in aggregate data, an approach that has since become widely
  adopted in modern macroeconomics.
  
  How do we best measure and analyze welfare and poverty? In his more
  recent research, Deaton highlights how reliable measures of individual
  household consumption levels can be used to discern mechanisms behind
  economic development. His research has uncovered important pitfalls
  when comparing the extent of poverty across time and place. It has
  also exemplified how the clever use of household data may shed light
  on such issues as the relationships between income and calorie intake,
  and the extent of gender discrimination within the family. Deaton's
  focus on household surveys has helped transform development economics
  from a theoretical field based on aggregate data to an empirical field
  based on detailed individual data.


His account in Google scholar provides the following "impact" data

\begin{array}{| r | r |}
  \hline 
\hline

\end{array}

See for starters the wikipedia article, for the "h-index" 

For the "i10-index" it reads:


  The i10-index indicates the number of academic publications an author has written that have at least ten citations from others. It was
  introduced in July 2011 by Google as part of their work on Google
  Scholar.


My question?  

Have you used A. Deaton's work in your studies or in your research? How?
Deaton's "Understanding Consumption" (1993) was one of the major sources I used when doing seminar work for my master's. In the end I decided to write my thesis about a different (somewhat related) subject after realising the empirical difficulties with what I planned on doing.

I have since chosen a different research subject, but Understanding Consumption is a book I have spent many hours with. It's a bit dated now, but still a decent read if you want to know about consumption and saving.
