BEATDiabetes stands for Behavioral Economic Approaches To Diabetes. Behavioral economics is the study of how people make complex decisions and why we often make decisions that are not in our own long-term best interests. Insights from behavioral economics have been used successfully to nudge people towards better choices in fields ranging from retirement savings to college enrollment to healthcare. The importance of the field was recognized when prominent behavioral economist Richard Thaler was awarded the Nobel Prize in Economics in 2017.
