Econ 152 Microeconomics Overview

Overview of Econ 152

Introductory course in microeconomics.
Focuses on individual and firm behavior in markets.
Analyzes how choices are made under conditions of scarcity.

Key Concepts

Supply and Demand
- Law of Demand: As price decreases, quantity demanded increases.
- Law of Supply: As price increases, quantity supplied increases.
- Market Equilibrium: Point where supply equals demand.
Elasticity
- Price Elasticity of Demand: Responsiveness of quantity demanded to price changes.
- Factors affecting elasticity: Availability of substitutes, necessity vs. luxury, time period.
- Income Elasticity: Sensitivity of demand to income changes.
Consumer Behavior
- Utility: Satisfaction received from consuming goods/services.
- Marginal Utility: Additional satisfaction from consuming one more unit.
- Budget Constraints: Limits of consumer spending based on income.
Production and Costs
- Factors of Production: Land, labor, capital, entrepreneurship.
- Short-run vs. Long-run: Distinction based on fixed and variable inputs.
- Cost Structures: Fixed costs, variable costs, average costs, marginal costs.
Market Structures
- Perfect Competition: Many firms, identical products, free entry/exit.
- Monopoly: Single seller, unique product, high barriers to entry.
- Oligopoly: Few firms, interdependent pricing strategies, potential for collusion.
Market Failures
- Externalities: Costs or benefits affecting third parties (e.g., pollution).
- Public Goods: Non-excludable and non-rivalrous goods (e.g., national defense).
- Information Asymmetry: Unequal knowledge between buyers and sellers.
Government Intervention
- Price Controls: Price ceilings (maximum prices) and price floors (minimum prices).
- Taxes and Subsidies: Impact on supply, demand, and market outcomes.
- Antitrust Policies: Regulation to promote competition and prevent monopolies.

Applications

Real-world scenarios illustrating microeconomic principles.
Case studies on market behaviors and government policies.
Analysis of current economic events through microeconomic lenses.

Study Tips

Review and understand graphical representations (supply/demand curves).
Practice with real-life examples to solidify concepts.
Utilize practice problems to apply theories on elasticity, costs, and market structures.

Overview of Econ 152

Introductory microeconomics course examining individual and firm behavior in markets.
Emphasis on decision-making processes under scarcity.

Key Concepts

Supply and Demand
- Law of Demand indicates that a decrease in price results in an increase in quantity demanded.
- Law of Supply shows that an increase in price leads to an increase in quantity supplied.
- Market Equilibrium occurs at the intersection of supply and demand.
Elasticity
- Price Elasticity of Demand measures how quantity demanded reacts to price changes.
- Influencing factors include the presence of substitutes, the distinction between necessities and luxuries, and the time frame for consumer adjustment.
- Income Elasticity assesses how demand shifts with changes in consumer income.
Consumer Behavior
- Utility refers to the overall satisfaction derived from consuming goods and services.
- Marginal Utility represents the added satisfaction gained from consuming an additional unit of a product.
- Budget Constraints define the limits on consumer spending based on available income.
Production and Costs
- Factors of Production consist of land, labor, capital, and entrepreneurship.
- The Short-run is characterized by some fixed inputs, while the Long-run allows for all inputs to be variable.
- Cost Structures include fixed costs, variable costs, average costs, and marginal costs which influence production decisions.
Market Structures
- Perfect Competition features many firms with identical products and ease of entry and exit.
- A Monopoly exists when a single seller offers a unique product with high barriers to entry.
- Oligopoly involves a small number of firms that influence each other's pricing and may engage in collusion.
Market Failures
- Externalities arise when costs or benefits affect third parties, such as pollution impacts.
- Public Goods are characterized as non-excludable and non-rivalrous, like national defense services.
- Information Asymmetry refers to discrepancies in knowledge between buyers and sellers that can lead to market inefficiencies.
Government Intervention
- Price Controls include price ceilings (maximum price limits) and price floors (minimum price thresholds).
- Taxes and subsidies can significantly alter supply and demand dynamics and market equilibrium.
- Antitrust Policies are regulations intended to stimulate competition and prevent monopolistic practices.

Applications

Real-world examples illustrate microeconomic principles in action.
Case studies explore market behaviors and the effects of government policies.
Current economic events can be analyzed through microeconomic frameworks for deeper understanding.

Study Tips

Familiarize with graphical representations, particularly supply and demand curves for visual comprehension.
Engage with real-life situations to reinforce understanding of key concepts.
Solve practice problems to effectively apply theories related to elasticity, cost structures, and market types.
