sellers Key Market Structures Perfect Competition This ideal model features a large number of firms selling identical products with free entry and exit perfect information and no market power for individual firms Monopolistic Competition Here numerous firms offer differentiated products that are close substitutes This creates a degree of competition but individual firms still hold some control over price Oligopoly A few dominant firms hold a significant share of the market Products can be either identical or differentiated Interdependence is a key feature meaning actions by one firm can significantly impact others Monopoly A single firm dominates the entire market facing no competition and possessing significant pricing power Handout 24 Practice Questions and Answers Question 1 Describe the key characteristics of a perfectly competitive market Answer A perfectly competitive market exhibits the following characteristics 2 Large Number of Firms Many small firms operate none of which hold a significant market share Identical Products Firms offer homogeneous products making them perfect substitutes for each other Free Entry and Exit New firms can easily enter the market and existing firms can exit without barriers Perfect Information Both buyers and sellers have complete knowledge of prices product quality and other market conditions No Market Power Individual firms have no ability to influence market price They are price takers accepting the prevailing market price Question 2 What are the key differences between perfect competition and monopolistic competition Answer While both market structures feature a large number of firms the following differences distinguish them Feature Perfect Competition Monopolistic Competition Product Identical Differentiated Price Control None Some Barriers to Entry None Low Information Perfect Imperfect Question 3 Explain the concept of interdependence in an oligopoly Answer In an oligopoly interdependence arises due to the limited number of firms The actions of one firm eg lowering prices launching a new product can have a direct and significant impact on the market share and profits of other firms This forces firms to constantly monitor and react to each others strategies leading to a dynamic and competitive landscape Question 4 Provide an example of a market that could be characterized by each market structure

competitive firm faces a horizontal demand curve meaning it can sell any quantity at the prevailing market price Therefore its marginal revenue MR is equal to the market price Monopoly A monopoly faces a downwardsloping demand curve reflecting its ability to set the price As it increases output it must lower the price to sell more units This leads to a marginal revenue curve that lies below the demand curve meaning MR is always less than price Question 6 Discuss the pros and cons of each market structure Answer Market Structure Pros Cons Perfect Competition High efficiency low prices consumer welfare innovation in the long run Low profits for firms potential for exploitation of workers Monopolistic Competition Product variety consumer choice innovation in the short run Higher prices than perfect competition inefficiency due to excess capacity Oligopoly Potential for economies of scale innovation competition in price and quality High prices collusion among firms limited consumer choice Monopoly Economies of scale potential for research and development Higher prices reduced consumer choice potential for inefficiency Question 7 How do barriers to entry influence market
