Denomination Effect

Decision-Making and Judgment Biases

The denomination effect is the tendency for people to be more willing to spend money when it is held in the form of several smaller denomination bills or coins than when the same total value is held as a single larger denomination bill. The economists Priya Raghubir and Joydeep Srivastava demonstrated the effect experimentally in a 2009 study, finding that participants given change in smaller bills spent more of it on discretionary purchases than participants given the equivalent amount as a single larger bill, even though the actual purchasing power was identical either way. The effect is discussed in behavioral economics as an example of mental accounting, in which money is not treated as perfectly fungible but is instead evaluated differently depending on its physical form or the psychological account it is perceived to belong to.
