Question 1 Suppose a firm's demand function is given as Q = 100 – 4P, where is the total market quantity and P is the market price. The fixed costs of the firm are 15 and their marginal cost is 10. (Note: The firm's total costs include the fixed cost along with marginal costs) - Determine the equilibrium price p", quantity o*, and profit of this monopolist - What profit-maximizing condition must a monopolist follow? Question 2 Consider a duopoly composed of two firms (Firm 1 and Firm 2) where the firms are setting their output quantities simultaneously. These two firms face the same cost situation C = 109, where i = {1, 2}. The market demand function for this duopoly is given by Q = 200 – 2P, where Q denotes total output. - Calculate the revenue, total costs, and profit for each firm - Determine the equilibrium quantity and price in this duopoly - Plot the reaction functions for each firm on an appropriately-labeled diagram - In the generalized case of a Cournot model, what happens to the equilibrium quantity and price as the number of firms increases? Question 3 A Stackelberg duopoly market is composed of two firms (Leader and Follower). The inverse market demand function is given by P = 200 – 20. The Leader's cost function is given by C, = 109, while the Follower's cost function is given by Cp = 597 Find the Leader's revenue, quantity produced, and profit Find the Follower's revenue, quantity produced, and profit - What would be the equilibrium quantity and price in this market? Provide an example of a Stackelberg (Leader-Follower) market

Question One
Determine the equilibrium price, quantity, and profit of this monopolist 𝑄 * 𝑅 *
Demand= 𝑅 = 100 – 4P
Fixed costs= 15
Marginal costs=10
TC= 15+10Q
Total Revenue=Q*P= 100P-4P2
MR= (100P-4P2)/ (100 – 4P)
At profit max MC=MR
Thus 10= 100P-4P2/ (100 – 4P)
10(100 – 4P) =100P-4P2
1000-40P=100P-4P2
100P+40P-4P2-1000=0
-4P2+140P-1000=0
P= {-140+- (√1402-4(-4*-1000)}/2(-4)
P= (-140+-...
