a. Explain the concept of elasticity of demand and the factors that affect it.
Answer:-
From the decision-making perspective, the firm needs to know effect of changes in any of the independent variables in the demand function on the quantity demanded. Some of these variables are under the control of management, such as price, advertising, product quality, and customer service. For these variables, management must know the effects of changes on quantity to assess the desirability of institution the change. Other variables, including income price of competitor’s products, and expectations of consumers regarding future prices, are outside the direct control of the firm. Nevertheless, effective forecasting of demand requires that the firm be able to measure the impact of changes in these variables on the quantity demanded.
The most common used measure of the responsiveness of the quantity demanded to changes in any of the variables that influence the demand function is elasticity. In general, elasticity may be through of as a ratio of the percentage(%) change in one quantity(or variable) to the percentage(%) change in
