Is it true that a merger between two firms that are not already in the top four by size can affect both the four-firm concentration ratio and the Her findahl-Hirshman Index? Explain briefly.
Suppose that the most popular car dealer in your area sells 10 percent of all vehicles. If all other car dealers sell either the same number of vehicles or fewer, what is the largest value that the Herfindahl index could possibly take for car dealers in your area? In that same situation, what would the four-firm concentration ratio be?

- Suppose that a small town has six burger shops whose respective shares of the local market are (as percentages of all hamburgers sold): 26%, 20%, 18%, 14%, 12%, 10%, What is the four-firm concentration ratio of the hamburger industry and what is the Hirchmann Herfindahl Index (HHI) for the hamburger industry in this town?arrow_forwardQuestion C2 The Australian Competition and Consumer Commission (ACCC) has opened an investigation regarding collusion between the two major firms producing fire protection gear for bush firefighters. The firms - Azure Associates and Blue Guard - contend that they are quantity competitors and that the prices they are charging are a result of an increase in price by their suppliers. As part of the case, the ACCC has noted that the Australian firefighters typically purchase their own protective gear and are thus price takers in the market. Both the ACCC and the two firms under investigation agree that the market demand can be described by the inverse demand function: P(Q)=240-Q, where Q is the total quantity provided by the two firms (i.e., Q=q₁ + 9B, where is the 9A amount produced by Azure Associates and q, is the amount produced by Blue Guard). All parties also agree that the two firms have identical production technologies and that the two firms have the same constant marginal cost of…arrow_forwardPRICE (Dollars per can) 2.00 1.80 1.60 Demand 1.40 1.20 1.00 0.80 0.60 0.40 0.20 0 0 MC = ATC MR 90 180 270 360 450 540 630 720 810 900 QUANTITY (Cans of beer) Monopoly Outcome $0.80 per can. Given this When they act as a profit-maximizing cartel, each company will produce 180 cans and charge information, each firm earns a daily profit of $144.00, so the daily total industry profit in the beer market is $288.00. Oligopolists often behave noncooperatively and act in their own self-interest even though this decreases total profit in the market. Again, assume the two companies form a cartel and decide to work together. Both firms initially agree to produce half the quantity that maximizes total industry profit. Now, suppose that Stargell decides to break the collusion and increase its output by 50%, while Schmidt continues to produce the amount set under the collusive agreement. Stargell's deviation from the collusive agreement causes the price of a can of beer to now $ , while Schmidt's…arrow_forward
