Study Notes

Basic Concepts

Microeconomics examines the behavior of individual economic agents (households, firms, markets) and their decisions regarding scarce resources.
It focuses on individual markets, not macroeconomic issues.
Key areas include supply and demand, production, costs, and market structures like perfect competition and monopoly.
Microeconomics helps understand price determination, resource allocation, and market failures.

Supply and Demand

Supply and demand are fundamental to price determination in markets.
Demand is the quantity consumers are willing and able to buy at various prices (inverse relationship).
Supply is the quantity producers are willing and able to sell at various prices (direct relationship).
Market equilibrium occurs where quantity demanded equals quantity supplied, establishing equilibrium price and quantity.

Elasticity

Elasticity measures the responsiveness of one variable to changes in another.
Types include price elasticity of demand, price elasticity of supply, income elasticity of demand, and cross-price elasticity of demand.
Price elasticity of demand shows the percentage change in quantity demanded due to a percentage change in price.
Inelastic demand: price change leads to a smaller proportional change in quantity demanded. Elastic demand: price change leads to a larger proportional change in quantity demanded.
Elasticity is crucial for understanding market impacts of price or other changes.

Production and Costs

Production transforms inputs (labor, capital, raw materials) into outputs.
Firms aim to minimize costs while maximizing output.
Cost curves illustrate fixed costs, variable costs, total costs, average costs, and marginal costs.
Cost curves guide output decisions, pricing, and resource allocation by firms.

Market Structures

Different market structures influence firm behavior and market outcomes.
Perfect competition: many small firms, homogeneous products, free entry/exit, perfect information; firms are price takers.
Monopoly: single seller, significant barriers to entry; monopolist can influence market price.
Other structures include monopolistic competition and oligopoly, each with unique characteristics relating to firms, differentiation, and market power.

Consumer Behavior

Consumer behavior studies individual choices allocating limited resources (time, income).
Key factors are preferences, budget constraints, and prices.
Consumer choice theory shows how individuals maximize utility subject to budget constraints.
Utility represents the satisfaction or benefit from consumption.

Externalities and Market Failures

Externalities occur when production or consumption impacts third parties not involved in the transaction.
Externalities can be positive (education) or negative (pollution).
Market failures arise when markets inefficiently allocate resources, often due to externalities.
Government intervention addresses market inefficiencies.

Game Theory

Game theory analyzes strategic interactions between rational agents.
It models situations where outcomes depend on choices made by multiple participants.
Game theory applies to firms' interactions and market competition.

Applications

Microeconomics has diverse applications in various fields.
Examples include business decisions, public policy analysis, and understanding market dynamics.
Tools aid in optimal pricing, resource analysis, and assessing the impact of regulations and policies.
