3. Reproduce the numerical example from the chapter on Monopolistic Competition in the book by Krugman & Obstfeld. If you do not have the book, here is the relevant information (the model and the equations are the same as those in the slides). Consider two countries, Home y Foreign, with the following market sizes: Sí = 900,000 and SF = 1,600,000. The demand function for industry iis represented by Qi (P; – P) In 30,000 While the total cost function is represented by TC = 750,000,000 + 5,000 ·Q (a) Compute the long-run equilibrium price and the long-run number of varieties in Home and in Foreign under AUTARKY. (b) Compute the long-run equilibrium price and the long-run number of varieties in the integrated market when there is FREE TRADE. Compare (a) and (b) and show that both countries are better off. 4. Suppose that the two countries that we considered in the numerical example of the previous exercise were to integrate their automobile market with a third country, the third country having an annual market of 3.75 million automobiles. Find the number of firms the production per firm and the price per automobile in the new integrated market post trade.

Continuing with the scenario in question 1, in the long run, the positive economic profits that the monopolistic competitor earns will attract a response either from existing firms in the industry or film outside. As those films capture the original films profit, what will happen to the original films profit-maximizing price and output levels?
If the firms in a monopolistically competitive market are earning economic profits or losses in the short run, would you expect them to continue doing so in the long run? Why?
Suppose that, due to a successful advertising campaign, a monopolistic competitor experiences an increase in demand for its product. How will that affect the price it charges and the quantity it supplies?
What is the relationship between product differentiation and monopolistic competition?
Aside from advertising, how can monopolistically competitive films increase demand for their products?
What stops oligopolists from acting together as a monopolist and earning the highest possible level of profits?
Consider the curve in the figure below, which shows the market demand. marginal cost, and marginal revenue curve for firms in an oligopolistic industry. In this example, we assume firms have zero fixed costs. Suppose the firms collude to form a cartel. What price will the cartel charge? What quantity will the cartel supply? How much profit will the cartel earn? Suppose now that the cane] breaks up and the oligopolistic firms compete as vigorously as possible by cutting the price and increasing sales. What will be the industry quantity and price? What will be the collective profits of all firms in the industry? Compare the equilibrium price, quantity, and profit for the cartel and cutthroat competition outcomes.
When OPEC raised the price of oil dramatically in the mid-1970s, experts said it was unlikely that the cartel could stay together over the long term-that the incentives for individual members. to cheat would become too strong. More than fort),r years later, OPEC still exists. Why do you think OPEC has been able to beat the odds and continue to collude? Hint: You may wish to consider non-economic reasons.
How can a monopolistic competitor tell whether the price it is charging will cause the firm to earn profits or experience losses?
Make a case for why monopolistically competitive industries never reach long-run equilibrium.
How can a monopolist identify the profit-maximizing level of output if it knows its total revenue and total cost curves?
