Final answer:
The correct answer is d. All of the above are correct. The price elasticity of demand for mobile phones will be higher if there is an improvement in the production technology. The price elasticity of demand will be lower if consumers perceive mobile phones to be a necessity. The price elasticity of demand is computed as the percentage change in the price of mobile phones divided by the percentage change in quantity of mobile phones.
Step-by-step explanation:
The correct answer is d. All of the above are correct.
The price elasticity of demand for mobile phones will be higher if there is an improvement in the production technology because it will lower the cost of production, making the price more elastic and demand more responsive to price changes.
The price elasticity of demand will be lower if consumers perceive mobile phones to be a necessity. When a product is perceived as a necessity, consumers are less likely to be price sensitive and therefore demand will be more inelastic.
The price elasticity of demand is computed as the percentage change in the price of mobile phones divided by the percentage change in quantity of mobile phones. This formula allows us to measure how responsive quantity demanded is to changes in price.
