Study Notes

Introduction to Economics

Economics is the social science studying how societies allocate scarce resources to satisfy unlimited wants and needs.
It encompasses two main branches: microeconomics and macroeconomics.
Microeconomics focuses on individual agents (households and firms).
Macroeconomics examines overall economy behavior.
Key concepts include scarcity, opportunity cost, supply and demand, and market equilibrium.

Scarcity and Opportunity Cost

Scarcity is a fundamental economic problem, limited resources vs. unlimited wants.
Opportunity cost is the value of the next best alternative forgone.
Every choice involves trade-offs and a cost of what could have been gained elsewhere.
Understanding opportunity cost is crucial for individual and societal efficiency.

Supply and Demand

Supply is the quantity producers offer at various prices.
Demand is the quantity consumers want to buy at various prices.
Supply and demand interact to determine price and quantity.
Supply influencers include input costs, technology, and regulations.
Demand influencers include consumer preferences, income, and related goods prices.
Market equilibrium is where supply and demand cross, establishing clearing price and quantity.

Microeconomic Concepts

Market structures (perfect competition, monopoly, oligopoly, monopolistic competition) impact market behavior.
Perfect competition is theoretical; many buyers and sellers, homogeneous products, free entry/exit, perfect information.
Monopoly is one seller with significant price control.
Oligopoly has a few large firms significantly impacting pricing.
Monopolistic competition: many firms sell differentiated products.
Consumer and firm behavior models explain decisions related to consumption, production, and investment.
Demand and supply elasticity measures responsiveness to price changes.

Macroeconomic Concepts

Macroeconomics analyzes economic growth, inflation, unemployment, and business cycles.
Gross Domestic Product (GDP) measures total final goods/services produced within a country.
Inflation is a general increase in price levels.
Unemployment is the percentage of the labor force actively seeking work but not employed.
Business cycles involve fluctuations in economic activity (expansion and contraction).
Fiscal policy uses government spending and taxation to influence the economy.
Monetary policy adjusts interest rates and money supply to affect aggregate demand.
Economic indicators (inflation, unemployment, GDP) monitor economic health and stability.

Economic Systems

Economic systems (capitalism, socialism, mixed economies) determine resource allocation.
Capitalism: private ownership, free markets, and profit motive.
Socialism: social ownership, centralized planning, distribution.
Mixed economies combine market and planned approaches.
Government roles differ significantly across systems.

International Economics

International trade involves exchanging goods/services across borders.
Comparative advantage is producing a good/service at a lower opportunity cost.
Trade benefits all participants by allowing specialization and efficiency.
Protectionism and globalization are key considerations.

Economic Models

Economic models simplify reality to analyze phenomena.
Models aid understanding economic relationships and predict reactions to changes.
Assumptions and simplifications focus on key factors and outcomes.
Examples include aggregate demand-aggregate supply (AD-AS) models and Phillips curves (inflation-unemployment trade-offs).
