Price Elasticity Of Demand (PED)
Muhtasari
If a shop raises its price by 10 per cent, does it sell a little less or a lot less? The answer decides whether the price rise makes the firm more money or less. Price elasticity of demand turns that question into a number you can calculate and act on.
In this lesson you will calculate PED from the formula, read its value (from perfectly inelastic to perfectly elastic), draw the matching demand curves, and link elasticity to the revenue a firm earns. By the end you will be able to advise a firm whether raising or cutting price will boost its takings.
Malengo
- calculation of PED using the formula
- interpretation of the significance of the PED value: perfectly inelastic, inelastic, unitary, elastic, perfectly elastic
- drawing and interpretation of demand curve diagrams to show different PED
- main influences on whether demand is elastic or inelastic
- effect of price changes on the amount spent by consumers and revenue raised by firms, shown both in a diagram and as a calculation
- relationship between PED and the amount spent by consumers and revenue raised by firms
- implications of PED for decision-making by consumers, workers, producers/firms and government
