Answer :
In a monopolistically competitive market, if a firm introduces a new, improved product, the demand curve for each of the other firms will shift inward, reducing the price and quantity received by those incumbents.
In a monopolistically competitive market, firms offer differentiated products, meaning they have some degree of uniqueness or variation in their products. Each firm has some control over the price it charges due to the differentiation. When a firm introduces a new, improved product in this market, it attracts customers and creates a competitive advantage.
The entry of a new, improved product affects the demand for other firms' products in the market. Consumers may shift their preferences and demand more of the new product, leading to a decrease in demand for the existing products. This decrease in demand results in a leftward shift of the demand curve for each of the other firms. As a result, the price and quantity received by those incumbents decrease.
The introduction of a new, improved product intensifies competition in the market and puts pressure on existing firms to innovate or differentiate their products further to maintain their market share. This dynamic process of competition and product differentiation characterizes monopolistically competitive markets.
