Study Notes

Microeconomics

Microeconomics is the study of how individuals, households, and firms make decisions in the face of scarcity.
Key concepts include supply and demand, market structures (perfect competition, monopoly, oligopoly, monopolistic competition), production, cost, and market equilibrium.
Supply and demand are fundamental to understanding how markets function. Demand represents the quantity of a good or service consumers are willing and able to buy at different prices, while supply represents the quantity producers are willing and able to offer at different prices.
Market equilibrium is the point where supply and demand curves intersect, determining the market price and quantity.
Elasticity measures the responsiveness of one variable to a change in another. Price elasticity of demand measures how sensitive quantity demanded is to changes in price.
Factors that influence market prices and quantities include changes in consumer preferences, income, prices of related goods, and expectations.
Production typically involves transforming inputs (e.g., labor, capital, raw materials) into outputs (goods or services). Production functions illustrate the relationship between inputs and outputs.
Costs are crucial for firms' decisions, as they directly affect profitability. Costs include fixed costs (e.g., rent) and variable costs (e.g., raw materials).

Macroeconomics

Macroeconomics studies the overall performance and behavior of the economy.
Key concerns include inflation, unemployment, economic growth, and international trade.
Gross Domestic Product (GDP) measures the total value of goods and services produced within a country's borders in a specific time period.
Inflation is a general increase in the prices of goods and services in an economy over a period of time. Deflation is the opposite—a general decrease in prices.
Unemployment refers to the proportion of the labor force that is actively seeking work but unable to find it.
Economic growth is an increase in the production of goods and services in an economy over a period of time, typically measured by changes in real GDP.
Fiscal policy involves government spending and taxation to influence the economy.
Monetary policy involves actions by the central bank to influence the money supply and credit conditions.
Aggregate Demand (AD) and aggregate Supply (AS) are important concepts in understanding macroeconomic fluctuations. AD represents the total demand for goods and services in an economy at different price levels. AS represents the total supply of goods and services at different price levels.
Business cycles, characterized by expansions and contractions in economic activity, are a recurring feature of market economies.
International trade involves the exchange of goods and services across national borders. Trade deficits and surpluses are important considerations.

Economic Systems

Economic systems define how societies allocate scarce resources to satisfy unlimited wants.
There are various economic systems including:
- Centrally planned economies: Government controls resource allocation and production.
- Market economies: Individuals and firms make decisions based on market forces of supply and demand.
- Mixed economies: Combine elements of both central planning and market mechanisms.
Factors of production: Land, labor, capital, and entrepreneurship are essential for producing goods and services.
Property rights provide incentives for investment, innovation, and economic growth.

Economic Theories

Various economic theories explain different aspects of the economy and how it functions.
Examples include:
- Keynesian economics: Focuses on aggregate demand and the role of government intervention to manage economic fluctuations.
- Classical economics: Emphasizes market forces and self-regulation of the economy.
- Supply-side economics: Highlights the importance of incentives for businesses and individuals to increase supply.
Models are used to simplify complex economic phenomena and analyze various situations and outcomes.

Economic Indicators

Statistical measures used to assess the performance of the economy.
Examples include GDP, inflation rates, unemployment rates, consumer price index (CPI).
These indicators provide insights into the current state of the economy and help policymakers make informed decisions.

Behavioral Economics

A field that integrates insights from psychology into economic analysis.
It considers how cognitive biases and psychological factors influence economic decisions.
Topics include limited rationality, framing effects, and prospect theory.
