Angus Deaton has long been one of my favorite economists, with work that ranges from the technical to the extremely practical. I particularly enjoyed his thoughtful comments on GDP in rich and poor countries (they consume different products, hard to compare) and happiness research (what does it mean when poor people tell us they’re happy?). Quartz has the best short summary, but see also his collection of popular writing and Google Scholar page. Also the Nobel announcement.
