What will be the nature of elasticity of demand of transportation and communication facilities for industrial development of a country?

Question

Accepted Answer

The correct option is 3:

The correct answer is Perfectly inelastic. This concept is fundamental when considering the demand for essential infrastructure like transportation and communication, especially in the context of industrial development. For industries to function, raw materials must be transported to factories, finished goods must be shipped to markets, and businesses must communicate instantly, regardless of the cost. These facilities act as critical and non-substitutable inputs—they are indispensable for industrial activity. Therefore, even if the price (or tariffs/fees) for transportation or communication changes, the quantity demanded by the industrial sector for these essential services will barely change, if at all, as any reduction in use would paralyze production. In the theoretical extreme of absolute necessity for a crucial input, the demand curve is vertical, representing perfectly inelastic demand ($	ext{E}_d = 0$).

The incorrect option is 1 (Elastic): Elastic demand means that a price change leads to a proportionally larger change in quantity demanded. This is typical for luxury items or goods with many close substitutes, which is not the case for core infrastructure required by an entire industrial sector.

The incorrect option is 2 (Perfectly elastic): Perfectly elastic demand ($	ext{E}_d = \infty$) implies that a minute price increase causes demand to drop to zero. This scenario is characteristic of a perfectly competitive market where firms can instantly switch suppliers for a product, which does not reflect the necessity and rigidity of essential infrastructure.

The incorrect option is 4 (Inelastic): Inelastic demand means quantity demanded changes less than proportionally to price changes ($	ext{E}_d < 1$). While transportation and communication are generally inelastic, "perfectly inelastic" is the stronger, more appropriate economic term here because industrial survival depends on using these services, making their demand extremely rigid and virtually unresponsive to price changes.
