Inverse elasticity rule Use the first-order condition (Equation 15.2 ) for a Cournot firm to show that the usual inverse elasticity rule from Chapter 11 holds under Cournot competition (where the elasticity is associated with an individual firm's residual demand, the demand left after all rivals sell their output on the market). Manipulate Equation 15.2 in a different way to obtain an equivalent version of the inverse elasticity rule: pMCp=sieQ,p , where si=qi/Q is firm i's market share and eQp is the elasticity of market demand. Compare this version of the inverse elasticity rule with that for a monopolist from the previous chapter.

Determine the type of market structure and state your reasons.
Perfect Picture Cameras: Perfect Picture Cameras is a national camera company. It competes with a couple of other national camera companies. In order to gain an upper hand in the market, Perfect Picture Cameras has differentiated its camera by including an automatic focus and flash. Perfect Picture Cameras has the ability to raise its prices because of its unique features. However, federal regulators are always watching the company to ensure that no collusion occurs with other camera companies.

Cornell Pharmaceutical, Inc., and Penn Medical, Ltd., supply generic drugs to treat a wide variety of illnesses. A major product for each company is a generic equivalent of an antibiotic used to treat postoperative infections. Proprietary cost and output information for each company reveal the following relations between price (marginal cost) and output:
P = $10 + $0.004Qc (Cornell)
P = $8 + $0.008 Qp (Penn)
1. Assuming these two firms make up the entire industry, determine the industry supply curve when P < $10.
2. Determine the industry supply curve when P > $10.

Two firms engage in Cournot competition in the Everlasting Gobstopper industry. The price elasticity of demand is-2. Firm 1 has aconstant marginal cost of $110.00 per unit, and firm 2 has a constant marginal cost of $181.50 per unit. If the two firms are currently inequilibrium, what is firm 2's share of the market?

onsider a homogenous good industry with four firms. Total demand is given by D(p)=200-p.The variable (=marginal) cost of each of the firms is c1=10, c2=20, c3=30 and c4=35. Firms compete in prices.
Suppose firms 1 and 2 merge into one entity and produce with a marginal cost of 15.
Which of the following statements is correct?
After the merger, total welfare increases by $500.
After the merger, total welfare decreases by $500.
After the merger, total welfare increases by $1000.
After the merger, total welfare decreases by $1000.
None of the above.

a) Find the inverse industry demand by solving forp, then graph the inverse industry demandwith price on they-axis.
b) How do you expect the price of the good to be relative to its marginal cost?c) How do you expect the Lerner Index to be in relation to 0 and 1? Will it be 0? Will it be 1?
d) Find the optimal supply and the equilibrium price in this market. Does the price match yourexpectations?
e) Calculate the Lerner Index and mark-up in this market. Does this match your expectationsfor the Lerner Index?

Which of the following do not qualify as potential driving forces capable of inducing fundamental changes in industry and competitive conditions?
1.Reductions in both supplier and buyer bargaining power and higher barriers to entry into the industry
2. Reductions in uncertainty and business risk, changes in who buys the product and how they use it, and diffusion of technical know-how across more companies and more countries
3. Changes in an industry's long-term growth rate and changes in cost and efficiency
4. Entry or exit of major firms, government policy changes and/or regulatory influences
5. Growing buyer preferences for a more standardized product instead of strongly differentiated products (or for a more differentiated product instead of nearly identical or weakly differentiated products.
