Study Notes
Introduction to Microeconomics
- Microeconomics studies the behavior of individual economic agents (households and firms) and the markets they interact in.
- It analyses how these agents make decisions influencing prices and quantities of goods and services.
- Key microeconomic concepts include supply and demand, elasticity, market structures (e.g., perfect competition, monopoly), production, cost, and market failure.
Consumer Theory
- Consumers' choices depend on preferences and budget constraints.
- Indifference curves display combinations of goods providing equal satisfaction.
- Budget lines show affordable goods combinations given income and prices.
- Utility maximization occurs where the indifference curve is tangent to the budget line.
- Key concepts include marginal utility, diminishing marginal utility, and the demand curve.
Production and Cost
- Firms aim for maximum profit through efficient production.
- Production functions link inputs (labor, capital) to outputs (goods and services).
- Short-run and long-run costs are vital for firms.
- Short-run costs include fixed and variable costs; long-run costs consider all inputs variable.
- Key concepts include economies of scale, diseconomies of scale, and cost curves (e.g., average total cost, marginal cost).
Market Structures
- Different market structures lead to varying competition levels.
- Perfect competition features many firms, identical products, free entry/exit, and perfect information.
- Monopoly has one firm with barriers to entry.
- Oligopoly has a few dominant firms.
- Monopolistic competition involves many firms with differentiated products and some barriers to entry.
- These structures impact pricing, output, and innovation.
Demand and Supply
- Demand represents consumers' willingness and ability to buy goods at various prices.
- Supply reflects producers' willingness and ability to offer goods at various prices.
- Market equilibrium occurs where quantity demanded equals quantity supplied.
- Factors affecting demand include consumer preferences, related goods prices, income, and expectations.
- Factors affecting supply include input prices, technology, and government regulations.
Elasticity
- Elasticity measures responsiveness of one variable to changes in another.
- Price elasticity of demand shows how quantity demanded reacts to price changes.
- Income elasticity of demand shows how quantity demanded reacts to income changes.
- Cross-price elasticity of demand shows how quantity demanded of one good reacts to a price change of another.
- Understanding elasticity is critical for pricing and production decisions.
Market Failure
- Market failure arises when the market doesn't allocate resources efficiently.
- Examples include externalities (positive or negative), public goods, and information asymmetry.
- Government intervention can potentially correct market failure.
- Policy responses include taxes, subsidies, regulations, and public goods provision.
