There are three firms in the chert industry. Their demand curves are linear and are given by the following equations.

Qi= αi–βiPi+ δijPj+ δikPk(i,j,k) = (1,2,3).

You are given the following information about these firms.

Firm 1         Firm 2            Firm 3

Prices          35.997          38.779            35.597

Outputs        319.95        175.599          211.94

Gross Margins     .444              .226                .2976

Furthermore, you are given the following diversion ratios:

D12= .25, D21= .20, D13= .25, D31= .40, D23 = .25, D32= .10.

  1. Write down the profit maximization conditions for each firm.
  2. Using these conditions and the other information given to calculate the unknown demand parameters and the marginal costs.
  3. Suppose that Firm 1 and Firm 2 want to merge. You are an analyst at CRAI, a well-known consulting firm. Calculate the UPPI indices for P1and P2. Assume 20% cognizable efficiencies.
  4. Calculate the post-merger equilibrium prices. Again, assume 20% cognizable efficiencies.

Homework Answers

Answer #1

Answer-1. Gross margin= gross margin is the difference between revenue and cost of goods sold divided by revenue.

Revenue-cost of good sold/revenue.

Gross margin is expressed as a percentage.

Net Margin= Net margin or net profit margin is measure of profitability. It is calculated by finding the net profit as a percentage of the revenue.

so we can solve (P-Mc)/P by using net margin because net margin is the real profit after deduction of all cost so deduction of marginal cost which means cost of single product give real value of at which marginal revenue is equals to marginal cost.

Answer-2. Cognizable efficiencies= Cognizable efficiencies defines as the best way to reach profit segment by using different tools like merger is one of them to come out of loss by combining with other company.

There are 3 firms in a market with differentiated products. The marginal cost of production for each firm is c=20. There are no fixed costs. The system of inverse demands in this market is given by: P1=120-q1-0.5(q2+q3) P2=120-q2-0.5(q1+q3) P3=120-q3-0.5(q1+q2) And the corresponding demand system is q1=60-1.5P1+0.5(P2+P3) q2=60-1.5P2+0.5(P1+P3) q3=60-1.5P3+0.5(P1+P2) a. Suppose the 3 firms operate independently, and choose prices simultaneously. Find the best response function of each firm to the prices of its two rivals. b. Find the equilibrium prices, and...

N firms, in a Cournot oligopoly are facing the market demand given by P = 140 – 0.4Q, where P is the market price and Q is the market quantity demanded. Each firm has (total) cost of production given by C(qi) = 200 + 10qi, where qi is the quantity produced by firm i (for i from 1 to N). New firms would like to enter the market if they expect to make non-negative profits in this market; the existing...

Consider a market with n ≥ 2 firms, where the demand for the product of firm i is given by qi = a − bpi + c times summation of pj, where a, b > 0 while c can be either positive or negative. Firms compete in prices. Suppose that all the firms have the same constant marginal costs. Find the equilibrium. How does it change with c and n? Under what condition(s) does this equilibrium exist? Suppose now that...

Consider a market with only two firms. Demand on this market is given by D(p)= 90 - 3p. Initially both firms have the same constant per-unit cost, specifically c1 = c2 = 20 . (a) What is the Nash equilibrium in this market if firms behave as Bertrand competitors? How much does each firm produce, what price do the firms charge, and what are their profits? (b) Now suppose that firm 1 acquires a new production technique that lowers its...
