Extra Credit (10 Points) A large number of firms sell an undifferentiated product whose demand is given by P=200−Q. Any firm can produce the product according to TC=20Q, so that MC=20. Supply is thus P=20. Find the price and quantity sold in the market. Calculate total revenue and profits across the firms in the industry. (4 points) A manager at one of the firms (let’s call it Eureka) gets an idea for distribution that changes its cost structure to TC=10+Q+0.5Q2 so that MC=1+Q. The idea is a secret, and no other firms in the industry are able to successfully implement it. What quantity does Eureka now sell? Calculate Eureka’s revenue and profit, if any. (6 points) Hint: As this is a competitive industry, MR=20. PLEASE SHOW ALL WORK FOR FULL CREDIT AND USE THE TEXT BOX PROVIDED

In Peru, domestic demand for steel is given by P=200−Q.  Domestic supply is given by P=40+Q. Find the price and quantity of steel consumed and produced in the domestic country if there is free trade. Steel is available on the world market at Pw=60. Calculate the imports, producer surplus, and consumer surplus. (3 points) Suppose the government imposes an import tariff of $10 per unit. What is the resulting domestic price, domestic production, domestic consumption, imports, consumer surplus, producer surplus, government revenue, and DWL (deadweight loss)?

Which of the following should you instruct a low back patient about?

Consumers in Germany have the following demand curve for monthly subscriptions to Topsify’s streaming music services: P = 30 − Q, while consumers in Bulgaria have the demand curve P = 20 – Q. Assume that the product has zero marginal costs but positive fixed costs. Suppose that the provider, Topsify, can set a different price in each country. Find the profit-maximizing price for each country and the quantity sold. (5 points) Suppose the European Union passes a law against country-specific pricing. Now the service must set a single price to be charged in both Bulgaria and Germany.

The market demand function is P=150−2*(Q1+Q2), where Q1 and Q2​ are the quantities produced by firm 1 and firm 2, respectively. Consider that these two firms are the only ones serving this market. Both firms have constant marginal costs MC1=MC2=20. Derive the reaction functions for both firms. (3 points) Find the Cournot equilibrium quantities for each firm and the market price. (4 points) If the firms collude, what price do they charge to maximize profit?
