The article discusses how behavioral economics can help improve policy decisions by offering new tools, better predictions, and new welfare implications. By incorporating insights from psychology into economic models, behavioral economics can help change behaviors like savings rates and estimate the effects of policies like income taxation more accurately. This approach can provide non-paternalistic recommendations for optimal policies and offer new ways to address model uncertainty. Overall, integrating behavioral features into economic analysis can be more beneficial than treating behavioral economics as a separate field challenging traditional economic assumptions.
