1. Ten firms compete in a market to sell product X. The total sales of all firmsselling the product are $1 million. Ranking the firms' sales from highest tolowest, we find the top four firms' sales to be $175,000, $150,000, $125,000.and $100,000, respectively. Calculate the four-firm concentration ratio in themarket for product X.

6. Two firms, Firm 1 and Firm 2 and are engaged in Cournot competition. The inverse demand they are facing is given by p = 50-q, with p being the price of the good, and q being total quantity demanded, given by q = 91 +92, where 9₁ and 92 are the productions of firm 1 and 2 respectively. The total cost of firm 1 is TC1(91) = q and of firm 2 is TC₂ (92) = 292. (a) Find the Cournot equilibrium and the price that corresponds to it. (b) Find the Lerner Index of each firm.
Ten firms compete in a market to sell product X. The total sales of all firms selling the product are $1,500,000. Ranking the firms' sales from highest to lowest, we find the top four firms' sales to be $310,000, $235,000, $205,000, and $ 140,000, respectively. Calculate the four - firm concentration ratio in the market for product X. Instruction: Enter your response rounded to two decimal places,
Once more, please consider a market with eight producers that produce a total of 30,000 units. Their output is broken down below: Firm's Firm Output One 7400 Two 1800 Three 4100 Four 5200 Five 1400 Six 2800 Seven 6600 Eight 700 According to our lecture, this industry likely to be an oligopoly because is not; a small number of firms produce a large amount of the output O is; a small number of firms produce a large amount of the output O is not; production is spread out among relatively many firms is; production is spread out among relatively many firms

1. Consider two duopolists who each have a constant marginal cost c = e2 = 3 and face inverse demand P = 15 – Q,where Q = Q1 + Q2 is the total output of both firms. 1. Find the Cournot equilibrium quantity for each firm, the resulting market price, and the profits for each firm. 2. Find the Stackelberg equilibrium quantities for each firm, and the price, and the profits for each firm supposing that Firm 1 is the industry leader. 3. Suppose that Firm 2 figures out a way to lower its marginal cost to ez = 0 while firm 1 still has a marginal cost equal to 1: c = 3. How does this affect the Cournot equilibrium quantities, price, and profits? 4. How does this affect the Stackelberg equilibrium (with Firm 1 still as the leader) quantities, price, and profits?

Assume that the competition between Boeing and Airbus can be characterized by the following matrix Airbus Produce Quit Boeing Produce 5/15 0/110 90/0 0/0 Quit where the first number in each cell denotes the payoff that Boeing receives and the second number is the payoff that Airbus receives. Then you would expect both Boeing and Airbus to produce Boeing to leave the market and Airbus to keep producing Airbus to leave the market and Boeing to keep producing that there will be no stable equilibrium
