If he demand for good 1 decreases in this situation, when it is a complement for good 2. (5). The inverse demand function measures the price at which a given quantity will be demand. The height of the demand curve at a given level of consumption measures willingness to pay for an additional unit of the good at that consumption level. （三） 课后练习 1.
