In 2015 the Prize in Economic Sciences in Memory of Alfred Nobel was won by Angus Deaton. He was awarded for his analysis of consumption, poverty, and welfare. In this paper we have presented the model of consumption co-authored by Deaton (AID model) in the context of postulated rationality of consumers. Also, Deaton’s research over long-run consumption, global poverty and connected phenomena was shortly discussed. Deaton’s merits in moving the spotlight from aggregated data to individual data was stressed. Additionally, the paper presents some biographical information.
