Study Notes
Industrial Organization
- Industrial organization studies market and industry workings, focusing on firm competition.
- It differs from microeconomics by emphasizing market interaction (pricing, competition) in imperfect markets (e.g., imperfect competition, oligopoly).
- The main goal is to explain four key areas: market power, acquisition of market power, implications of market power, and the role of public policy in managing market power.
Market Power
- Market power is the ability to raise prices above marginal cost and earn more than normal profits.
- A study shows market power is low in the American economy, consistent with findings from the Chicago school.
- Industries with numerous firms typically have little or no significant market power. However, Some industries exhibit substantial market power.
Acquiring and Maintaining Market Power
- Firms acquire and maintain market power through various strategies:
- Legal protection, shielding firms from competition.
- Establishing a reputation to deter new entrants
- Offering valuable services, like connected devices ecosystem (e.g., Apple).
Implications of Market Power
- High prices reduce consumer welfare and lead to inefficient resource allocation.
- Firms with market power often have less incentive for cost/efficiency improvements, impacting overall productive efficiency.
- Government intervention to maintain market power can lead to rent-seeking behavior.
Role of Public Policy
- Public policy aims to mitigate negative outcomes resulting from market power, such as price increases and reduced competition.
- Tools used for this include: economic regulations (to control firms with near-monopoly or monopoly position) and antitrust policies (competition policies). Industrial policies aim to assist domestic firms against foreign competition.
Consumers
- The demand function reveals consumer tastes and preferences, helpful to firms.
- Consumer’s choices will be based on their available money (budget constraint), tastes (indifference curves), and prices of the different goods.
- Consumer surplus is the price difference between their willingness to pay and the actual price for a good, signifying economic efficiency.
- Demand elasticity measures the responsiveness of demand to price changes, affecting revenue and profit.
Demand Elasticity
- Demand elasticity measures the responsiveness of demand to price changes.
- Elastic demand means large changes in demand with small price changes whereas inelastic demand reflects a smaller change in demand with a large change in prices. Revenue falls when elasticity is less than -1; increases when elasticity is greater than -1 and remains the same when elasticity is -1.
- Cross-price elasticity measures the responsiveness of demand for one good to changes in the price of another good.
- Income elasticity indicates a good’s consumer reaction to income changes.
Income Elasticity
- Normal goods have positive income elasticity (demand increases with income).
- Inferior goods have negative income elasticity (demand decreases with income).
Production Side of the Market
- Firms transform inputs (labor and capital) into outputs (goods and services)
- The production function describes how inputs are combined to yield outputs given specific processes.
- An isoquant curve illustrates different input combinations yielding the same level of output.
- A firm’s cost function shows the least cost of producing particular output levels.
- Marginal cost (MC), average cost (AC), and total cost (TC) are central cost measures that help firms to decide what quantities of output to produce.
Pricing in Markets
- Firms often face a trade-off between the quantity they sell and the price.
- The price should ideally be set at the level where marginal cost is equal to marginal revenue.
- Elasticity of demand influences price decisions, and elasticity of demand impacts marginal revenue. (higher the elasticity, the lower the possible price markup).
Oligopoly
- In an oligopoly market, a small number of firms have significant market power, influencing each other's strategic decisions and leading to price manipulation (e.g., collusion, price wars).
- Strategies of firms in oligopoly, such as pricing decisions and production quantity, consider how their rivals will react.
Perfect Competition
- Perfect competition is a benchmark and market structure characterized by numerous independent firms and homogeneous products, where no single firm exerts much influence on market price.
- Firms are price takers because products are interchangeable with no noticeable differences.
- Demand curve faced by the firms is flat or horizontal.
Collusion and Price Wars
- Firms can potentially gain by colluding and acting as if they were a monopoly, to raise prices and obtain larger profits, but explicit collusion is illegal.
- Tacit collusion happens as a result of firms recognizing their mutual dependence and adjusting pricing decisions to avoid the potential of price wars.
Price Discrimination
- Price discrimination involves charging different prices to different consumers based on their willingness to pay. Different types exist, including versions and nonlinear pricing.
- In the case of perfect price discrimination, the seller captures the total consumer surplus; in practice, it is usually quite complex to implement.
Mergers
- Firms engage in mergers and acquisitions (Mergers and Acquisitions) to consolidate their market position and gain competitive advantages.
- Horizontal mergers (between firms within the same industry) can increase market concentration, impacting consumer prices, and possibly resulting in higher profits.
- Vertical mergers (between firms at different stages in the production or supply chain) can control the production process and reduce costs for the manufacturer.
- Conglomerate mergers (between firms in unrelated businesses) aim to diversify and expand into new markets.
Market Structure
- Market structure refers to characteristics of the market or industry (e.g., number of firms, degree of competition, type of products).
- Market concentration measures the concentration of market share among a smaller number of firms.
- High market concentration, as opposed to low market concentration, leads to less competition, making it easier for surviving firms obtain greater market power.
