Definition: Arc elasticity of demand measures elasticity between two points on a curve – using a mid-point between the two curves. On most curves, the elasticity of a curve varies depending on where you are. Therefore elasticity needs to measure a certain sector of the curve.

Definition: Price elasticity of demand (PED) measures the responsiveness of demand after a change in price. Example of PED If price increases by 10% and demand for CDs fell by 20% Then PED = -20/10 = -2.0 If the price of petrol increased from 130p to 140p and demand fell from 10,000 units to 9,900 …
Income elasticity of demand (YED) measures the responsiveness of demand to a change in income. For example, if your income increase by 5% and your demand for mobile phones increased 20% then the YED of mobile phones = 20/5 = 4.0 Definition of Inferior Good This occurs when an increase in income leads to a …
