Solution
a
Monopolistic Competition and Market Entry: In a monopolistically competitive market, firms have some degree of market power due to product differentiation. When new firms enter the industry, they increase the number of products available to consumers
b
Demand Curve for Existing Firms: The entry of new firms leads to a decrease in the demand faced by existing firms because consumers now have more options to choose from. This causes the demand curve for existing firms to shift to the left
c
Elasticity of Demand: As the number of substitutes increases with the entry of new firms, the demand for an existing firm's product becomes more elastic because consumers can more easily switch to other products
Answer
(D) The demand curve for existing firms decreases and gets more elastic.
