Households in the U.S. and other developed countries frequently face complex financial decisions, such as managing retirement savings or health insurance. To help navigate these challenges, a growing range of financial advice options has emerged. These include traditional face-to-face guidance from advisors, automated robo-advice, and an expanding selection of online educational resources and videos. While extensive research has focused on the supply side of financial advice, particularly issues like conflicts of interest, much less is known about how individuals receive or respond to advice.
