If behavioural economics begins to influence policy and regulation in retail finance, I anticipate changes in the way the game is set up
If you have had the occasion to have economist and Nobel laureate Richard Thaler sign a book for you, it’s likely that you have one that says, “Nudge for good" or “Misbehave for good". Nudge and Misbehaving are books written by Thaler. Nudge, written earlier than Misbehaving, is about tweaking the choice architecture so that people make better decisions. For example, if we know that people will choose one item out of the first three on a menu card, a nudge would put healthy food in those spaces, while keeping all the other choices at number four and below. Nudges work to help us overcome our biases that prevent us making good decisions. Bad nudges have been used by corporations to trick us into doing what they want and may not be in our interest. For example, an auto tick on a travel insurance policy on an airline website is a bad nudge. Thaler wants nudges to be used for good. He wants them used for setting up the game so that average people take decisions that work for them. For example, a positive nudge is the Save More Tomorrow programme (bit.ly/2hYxfGy) that allows people to promise to save more next year.
