Question

Quizplus · Accepted Answer

The demand for business products is derived, meaning that it is dependent on the demand for the consumer goods that those products help to produce. In some industries, there are many sellers of essentially homogeneous products (such as basic industrial chemicals or certain types of machinery) which means that buyers have many options to choose from and can easily substitute one seller for another, leading to an elastic demand curve. However, the overall demand for these products may be inelastic as the demand for the consumer goods they help produce may not fluctuate as much with changes in price. Additionally, many business buyers may use reciprocity in their buying, meaning they give preference to suppliers who also buy from them, which can further limit their willingness to substitute sellers.
