Suppose you manage a local grocery store, and you learn that a very popular national grocery chain is about to open a store just a few miles away. Use the model of monopolistic competition to analyze the impact of this new store on the quantity of output your store should produce (Q) and the price your store should charge (P). What will happen to your profits?
Please show graphically and explain your reasoning in detail. For example, how and why do profits change? How can that be seen on the graph?
What could you do to defend your market share against the new store?
