Summary

This topic explains why price elasticity of demand (PED) often differs between primary commodities and manufactured goods. It links the observed elasticity to determinants such as availability of close substitutes, degree of necessity, proportion of income or production costs, and the time consumers or firms have to adjust. Understanding these differences helps predict how quantity demanded will respond to price changes for different types of products.
