Final answer:
The local grocery store in a monopolistic competition market will likely see a decrease in demand and profits with the entry of a national chain. Strategies to maintain market share include improving customer service, focusing on unique goods, and strengthening community ties.
Step-by-step explanation:
Analysis of the Impact of a New Store on a Local Grocery Store
When a new competitor such as a popular national grocery chain enters a market, which previously had a local grocery store operating under monopolistic competition, several changes can be expected. As the new store begins operation, customers might be lured away, affecting the demand for the local grocery store's products. Consequently, the local store may need to adjust the quantity of output (Q) and price (P) to remain competitive. In general, the quantity produced may decrease and prices may drop to retain customers.
Impact on the Business
The opening of the new store is likely to redirect some of the customer base, leading to decreased demand for the local store's products. This shift in demand will reduce the market share and profits of the local store. Unless the local store differentiates itself or competes effectively on another front, it will face a squeezing of its profit margins. On a graph, this is typically shown by a leftward shift in the demand curve, which leads to a lower equilibrium price and quantity.
Strategies to Defend Market Share
To defend against the market share erosion, the local grocery store could implement strategies like improving customer service, focusing on unique or local products, and strengthening customer relationships. Offering loyalty programs or engaging in community events could also help in retaining customers and potentially attract new ones.
