Study Notes
Perfect Competition
- Assumptions: Many buyers and sellers, homogeneous products, free entry and exit, perfect information, and firms are price takers.
- Price Taker: A firm that must accept the market price for its product; it cannot influence the price.
- Profit Maximization Rule: Produce where marginal cost equals marginal revenue (MC = MR).
Long-Run Industry Adjustment to Increased Demand
- In the long run, increased demand leads to profits for firms.
- This encourages new firms to enter the market.
- Increased supply reduces prices and profits until they return to normal.
Monopoly
- Assumptions: Single seller, unique product, significant barriers to entry.
- Barriers to Entry: Legal restrictions, economies of scale, control of essential resources.
- Price Searcher: A firm that has some control over the price it charges, as it faces a downward-sloping demand curve.
- Profit Maximization Rule: Produce where marginal revenue equals marginal cost (MR = MC).
Differences Between Perfect Competition and Monopoly
- Perfect Competition: Many firms, price takers, zero economic profit, and free entry/exit.
- Monopoly: Single firm, price searcher, potential economic profit, significant barriers to entry.
Monopolistic Competition
- Assumptions: Many sellers, differentiated products, relatively easy entry and exit.
- Profit Maximization Rule: Similar to a monopoly, firms produce where marginal cost equals marginal revenue (MC = MR).
Oligopoly and Cartel Theory
- Oligopoly: A market structure with a small number of large firms.
- Cartel: A group of firms that collude to restrict output and raise prices.
Problems of a Cartel
- Maintaining Collusion: Members may cheat on the agreement to increase profits.
Contestable Markets
- Contestable Markets: Markets where the threat of potential entrants can constrain the behavior of existing firms.
Regulating Natural Monopolies
- Price Regulation: Setting a price below the monopoly price.
- Profit Regulation: Limiting the firm's allowable profit.
- Output Regulation: Mandating a certain level of output.
Derived Demand
- Derived Demand: The demand for a factor of production (like labor) is derived from the demand for the good or service it produces.
Marginal Revenue Product (MRP) and Value Marginal Product (VMP)
- MRP: The additional revenue a firm receives from hiring one more unit of a factor.
- VMP: The additional revenue a firm receives from employing an additional unit of a factor, calculated by multiplying marginal output of the factor by the output price.
- Marginal Factor Costs (MFC): The additional cost incurred by employing one more unit of a factor
Optimal Factor Employment
- Firms employ factors up to the point where marginal revenue product equals marginal factor cost (MRP = MFC).
Shifts in Labor Demand Curve
- Factors that shift the labor demand curve include changes in output price, productivity of labor, and prices of other factors.
Elasticity of Labor Demand
- Measures the responsiveness of employment to changes in the wage rate and is measured using the proportionate change in the quantity of labor demanded divided by the proportionate change in the wage rate
Shifts in Labor Supply Curve
- Factors affecting the labor supply curve include changes in the population, preferences about work hours, and opportunities in alternative jobs.
Factors Affecting Wage Rates
- Wage rates are affected by supply and demand of labor, unionization, productivity and market conditions
Labor Unions
- Objectives: Higher wages, better working conditions, job security.
- Wage-Employment Trade-off: Higher wages can lead to reduced employment.
- Relationship with Elasticity of Labor Demand: The elasticity of labor demand influences the effectiveness of union wage increases.
Income Inequality
- Gini Coefficient and Lorenz Curve: Tools to measure income inequality. The Gini coefficient ranges from 0 (perfect equality) to 1 (perfect inequality).
- Factors Contributing to Income Inequality: Education, skills, discrimination, and technological changes.
Interest Rates
- Nominal Interest Rates: The interest rate without adjustment for inflation.
- Real Interest Rates: The interest rate adjusted for inflation.
Present Value
- Present Value: The current worth of a future sum of money or stream of cash flow.
Market Failures
- Market Failures: Situations where the free market fails to allocate resources efficiently.
- Positive Externalities: Benefits to third parties not included in the market price.
- Negative Externalities: Costs to third parties not included in the market price
Externalities' Impact:
- Externalities affect market output and prices because they change social costs/ benefits.
Marginal Social Costs/Benefits, Socially Optimal Output
- Marginal Social Costs (MSC): Incorporate the private cost and any external cost.
- Marginal Social Benefits (MSB): Integrate the private benefit and any external benefit.
- Socially Optimal Output: The quantity where MSC = MSB, leading to allocative efficiency.
Environmental Policies
- Types: Taxes, subsidies, tradable permits.
- Benefits: Reduced pollution, improved environmental quality.
- Disadvantages: Potential costs for businesses and consumers.
Asymmetric Information
- Asymmetric Information: When one party in a transaction has more information than the other.
Trade Restrictions
- Types: Tariffs, quotas, subsidies.
- Implications for Consumers and Producers: Tariffs raise prices and reduce quantity for consumers, protect domestic producers, but reduce overall efficiency.
Comparative Advantage
- Comparative Advantage: The ability of a country to produce a good or service at a lower opportunity cost than another country.
Arguments for Trade Restrictions
- National Security: Protecting industries crucial for national defense.
- Infant Industry Argument: Protecting new industries that are not yet competitive.
- Unfair Competition: Countering subsidies or dumping practices by other countries.
