A systematic review of the nudge literature and an examination of its applications across different domains reveals that: (i) a nudge, in the sense of using choice architecture to push people to choose desired results, works well; and (ii) a nudge, in the sense of pushing people to choose desired results so that people will be better off, remains questionable. In financial markets, regulators and financial intermediaries currently use nudge theory to: (i) adjust how investment choices are presented to investors; and (ii) provide information in a selective way. Besides nudging investors, it is also possible for regulators to nudge financial intermediaries towards making more ethical decisions.
