    I have the worst professor I've ever had for Intermediate Micro. Unfortunately, the textbook (the same Varian one everyone seems to use for this class) doesn't do a great job explaining things either. I've been struggling to find any resources to help me, but this was one of the first times I've understood what was happening. I can't believe how simple this is. Thank you!

    Another way to solve this problem is by use of Cramer's Rule.
    This is done by simplifying the equation. In this case,
    100-40=60
    Firm 1 = 60-2q1-q2
    Firm 2 = 60-q1-2q2
    Use Cramer's rule.
    (-2*-2) - (-1*-1) = 3
    (60*-2) - (60*-1) = -60
    -60/3 = 20 (drop the negative in this case)
    Thus 20 is the equilibrium

    With the collusion outcome, we solve for the monopoly profit-max. output level and price. We will assume the two firms produce half the market output. Here's the math:
    P= 100 - Q. Now solve for total revenue to get TR = 100Q - Q^2. Taking the derivative of TR gives marginal revenue which equals MR = 100 - 2Q. Set MR equal to marginal cost. Because total cost = 40Q, MC = 40
    MR = MC
    100 - 2Q = 40.
    Solve for Q.
    Q = 30 (each firm produces 15 units of output)
    P = 100 - Q = 100 -30 = $70

    Determine the value(s) of X for which the Justice department will deny them the merger.

    b) if we did know the amount the other producer would supply, would that be like a price leadership problem, where total demand minus its supply is the other's D, right?
    c) is this not equivalent to Nash equilibrium? LIke the least bad option considering any amount the other might produce?
    d) D'u have vids on price bundling?

    • @EconomicsinManyLessons
      @EconomicsinManyLessons  2 года назад

      If these firms form a cartel and act like a monopoly, the marginal revenue is MR = 100 - 2Q (I derived this from the inverse market demand: P = 100 - Q). MC is 40.
      MR = MC
      100 - 2Q = 40
      2Q = 60
      Q= 30 (the total market output is 30...we can assume each firm produces 15 units.
      The market price is P = 100 - 30 = $70.
