What is the term for a good that typically complements another product and may increase its consumption?

The term that refers to a good that complements another product and may enhance its consumption is "complement." Complements are goods that are often used together, meaning that when the price of one good decreases or its availability increases, the demand for both goods tends to rise. For example, if the price of printers decreases, the demand for ink cartridges may also increase, as they are used together. This relationship highlights how the presence of one good can enhance the utility or consumption of another good.

In contrast, substitutes are goods that can replace one another, meaning that an increase in the price of one might lead to an increase in demand for the other, rather than an increase for both. Normal goods and inferior goods are terms related to income effects on demand; normal goods see increased demand with rising incomes, while inferior goods see decreased demand as incomes rise. None of these terms capture the idea of goods that work together in consumption as complements do.
