I know what you are thinking. This sounds like a joke, but it is not. There really is a What-The-Hell Effect and we will get to it in a moment. First let’s talk about the Denomination Effect. Let’s say you are leaving home and want to carry some cash with you. You have the choice of either taking a $20 bill or $20 in smaller denominations. Should this make any real difference to how much you are likely to spend? After all $20 is $20, right? Not quite. Turns out the denomination in which money is carried does have an impact on spending behavior. Two researchers recently published an article detailing the effects and we’ll take a closer look at it here.
