Men are bigger tightwads than women; younger people are more likely to be spendthrifts than older people; and the more educated a person is the more likely he or she is to be a tightwad. While ”tightwad” and ”spendthrift” are not exactly labels that most people would welcome in a discussion of their spending habits they are valuable as predictors of consumer behavior. Indeed Scott Rick a visiting professor at Wharton and two colleagues recently came up with a scale to determine the extent to which people are tightwads or spendthrifts -- and what the implications are for retailers trying to more accurately target potential buyers in their stores and on their websites.
