Term wants and needs Definition: These are the unfulfilled desires that motivate human behavior and that when satisfied improve human well-being. They include both physiological or biological requirements for maintaining life (needs) and the psychological desires which make life more enjoyable (wants). However, when push comes to shove, and the nitty gets down to the gritty, it matters very little to markets if people need goods or want goods, so long as they are motivated to buy the goods to satisfy wants and needs.
