The Royal Swedish Academy of Sciences' announcement of the prize explains that Thaler "has incorporated psychologically realistic assumptions into analyses of economic decision-making. By exploring the consequences of limited rationality, social preferences, and lack of self-control, he has shown how these human traits systematically affect individual decisions as well as market outcomes.
"His empirical findings and theoretical insights have been instrumental in creating the new and rapidly expanding field of behavioral economics, which has had a profound impact on many areas of economic research and policy."
The Academy cited many settings in which behavioral insights have enriched the research dialogue, including the study of household saving, the formation of prices in financial markets, the role of fairness in setting wages and prices, and the potential for "nudges" to influence consumer behavior. The Academy's description of the ways in which Thaler's work has been applied may be found here.

Thaler is the Charles R. Walgreen Distinguished Service Professor of Economics and Behavioral Science at the Booth School and a research associate in the NBER's Asset Pricing Program. In 1992, he and Robert Shiller launched the NBER Working Group on Behavioral Economics, which has served as an important forum for researchers in this field. He served as co-director of the group until 2016.
