Study Notes

Microeconomic Definitions and Concepts

Microeconomics is the study of individual economic agents like individuals, households, and firms, and how their decisions affect markets.
It focuses on the behavior of individual agents, not the overall economy.
Microeconomics uses models to understand how price and quantity are determined in particular markets.

Key Concepts in Microeconomics

Demand: The relationship between a good's price and the quantity consumers are willing and able to buy.
Supply: The relationship between a good's price and the quantity producers are willing and able to sell.
Market Equilibrium: The intersection of supply and demand curves, establishing market price and quantity.
Elasticity: Measures the responsiveness of one variable to changes in another (e.g., price elasticity of demand, supply).
Maximizing Behavior: Economic agents (consumers and firms) aim to maximize utility/satisfaction (consumers) or profit (firms).
Opportunity Cost: The value of the next best alternative sacrificed when making a choice.
Marginal Analysis: Analyzing the additional benefit or cost of one more unit of an action or good.

Market Structures

Perfect Competition: Many buyers and sellers, homogenous products, free entry/exit, perfect information.
Monopoly: One seller, unique product with no close substitutes, significant barriers to entry.
Monopolistic Competition: Many sellers with differentiated products, some price control, easy entry and exit.
Oligopoly: Few large sellers, offering similar or identical products, strategic interaction is key.

Consumer Behavior

Utility Maximization: Consumers seek to maximize satisfaction (utility) given budget constraints.
Indifference Curves: Show combinations of goods providing the same level of satisfaction.
Budget Constraints: Represent affordable combinations of goods given income and prices.
Marginal Rate of Substitution (MRS): The rate a consumer is willing to trade one good for another while maintaining the same level of satisfaction.

Production and Costs

Production Functions: Show the relationship between inputs (e.g., labor, capital) and outputs (e.g., goods, services).
Short-Run vs. Long-Run Production: Short-run: one fixed input; long-run: all inputs variable.
Cost Curves: Show the relationship between output and costs (total, average, marginal).
Economies of Scale: Decreasing average cost as output increases.

Market Failures

Externalities: Costs or benefits not reflected in market prices, imposed on third parties.
Public Goods: Non-excludable and non-rivalrous (e.g., national defense).
Asymmetric Information: One party in a transaction has more information than the other.
Market Power: A firm's ability to influence market price.

Market Interventions

Price Ceilings and Price Floors: Government-imposed price restrictions affecting market equilibrium.
Taxes and Subsidies: Government interventions influencing market outcomes through prices and quantities.
Regulation: Government actions controlling and influencing market behavior.
