Explain the concept of price elasticity of demand. What are its determining
factors?
The price elasticity of demand is a measure of the responsiveness of
demand for a product to change in price. Demand is said to be elastic when
a small change in price produces a large change in demand; it is said to be
inelastic when a large change in price produces only a small change in
demand.
The elasticity of demand for a product in a given country is determined by a
number of factors, of which income level and competitive conditions are the
two most important. Price elasticity tends to be greater in countries with
low income levels. Consumers with limited incomes tend to be very price
conscious; they have less to spend, so they look much more closely at price.
In general, the more competitors there are, the greater consumers’
bargaining power will be and the more likely consumers will be to buy from
the firm that charges the lowest price. Thus, many competitors cause high
elasticity of demand. In such circumstances, if a firm raises its prices above
