What is limit pricing? (a) Suppose your firm produces a product at a constant marginal cost equal to $1. Suppose the elasticity of demand is -3. What is the profit-maximizing price if one ignores the possibility of entry? (b) Suppose at the above price economic profits are quite large, so your firm can expect entry. Assume that if one firm enters it would increase the elasticity of demand from -3 to -4, while if two firms enter it would increase the elasticity of demand to -6. What do you recommend that the firm do to deter entry? Discuss briefly.
