Summary
This topic explains why price elasticity of demand (PED) matters for firms and governments. PED shows how quantity demanded responds to price changes, which helps firms set prices (including price discrimination and surge pricing) to maximise sales revenue and helps governments predict tax revenue and the effectiveness of taxes on demerit goods. Understanding determinants of PED (substitutes, necessity, proportion of income, time) clarifies why primary commodities tend to be price inelastic while manufactured goods tend to be price elastic.
