Study Notes

Microeconomics Overview

Microeconomics studies individual economic units (households, firms, industries). It analyzes how these units make decisions about allocating limited resources.
Macroeconomics studies the economy as a whole. It examines national income, inflation, unemployment, and economic growth.
Economy is the system organizing the production, distribution, and consumption of goods and services.
Scarcity exists because resources are limited, while human wants are unlimited.
Opportunity Cost is the value of the next best alternative forgone when a choice is made.
Central Economic Problems arise from scarcity: deciding what to produce, how to produce, and for whom to produce.

Consumer Behavior

Utility is the satisfaction or pleasure derived from consuming a good or service.
Total Utility (TU) is the total satisfaction obtained from consuming a given quantity of a good.
Marginal Utility (MU) is the additional satisfaction gained by consuming one more unit of a good.
Law of Diminishing Marginal Utility states that as more units of a good are consumed, marginal utility decreases.
Budget Line shows all possible combinations of goods a consumer can purchase with their income at prevailing prices.
Consumer Equilibrium occurs when a consumer maximizes satisfaction given their income and prices.

Production and Costs

Production Function shows the maximum output achievable with given inputs.
Law of Variable Proportions describes how the marginal product of a variable input changes as it increases, first increasing, then decreasing, and finally becoming negative while a fixed input remains constant.
Fixed Costs do not change with the level of output.
Variable Costs change with the level of output.
Total Cost (TC) is the sum of fixed and variable costs at a given level of output.
Marginal Cost (MC) is the additional cost of producing one more unit of output.
Average Cost (AC) is the cost per unit of output (Total Cost divided by the quantity of output).

Perfect Competition

Market is a place where buyers and sellers interact to exchange goods and services.
Perfect Competition is a market structure with many buyers and sellers, homogeneous products, free entry/exit, and perfect knowledge.
Revenue is the income earned by a firm.
Total Revenue (TR) is the total income earned (Price multiplied by Quantity sold).
Average Revenue (AR) is revenue per unit of output (TR divided by Quantity sold).
Marginal Revenue (MR) is the additional revenue earned from selling one more unit of output.
Producer's Equilibrium in perfect competition occurs when Marginal Revenue equals Marginal Cost.

Market Equilibrium

Market Equilibrium occurs when quantity demanded equals quantity supplied at a given price.
Excess Demand occurs when quantity demanded exceeds quantity supplied.
Excess Supply occurs when quantity supplied exceeds quantity demanded.
Price Ceiling is a government-imposed maximum price.
Price Floor is a government-imposed minimum price.

Non-Competitive Markets

Monopoly is a market structure with one seller controlling the entire market with no close substitutes.
Monopolistic Competition involves many sellers offering differentiated products/services with some control over price.
Oligopoly is a market structure with a few large firms dominating the market, often with significant entry barriers.
Cartel is a group of firms colluding to control prices and limit competition.
