Two firms control an industry and engage in Cournot competition. The price elasticity of demand is -2.50. If one of the firms has a constant marginal cost of $705.00 per unit and controls 75.00 percent of the industry, what is the equilibrium price? (Round to two decimals if necessary.)
From Lerner's Index we know :-
Given,
MC = $705
Market Elasticity of Demand = -2.50
Share of firm = 75% = 0.75
So we can calculate Elasticity for the firm as per it's market share :-
So, E = Market Elasticity ÷ Market power
E = -2.50 ÷ 0.75
E = -10/3
Now, Using the formula :-
Hence,
Equilibrium price is $1007.14
