Study Notes

Introduction to Economics

Economics is the social science that studies how societies allocate scarce resources to satisfy unlimited wants and needs.
It examines individual choices, market behavior, and the overall performance of economies.
Key concepts include scarcity, choice, opportunity cost, and efficiency.

Microeconomics

Microeconomics focuses on the behavior of individual consumers, firms, and markets.
It analyzes how prices are determined in individual markets and how these individual decisions affect the overall economy.
Key concepts include supply and demand, elasticity, market structures (perfect competition, monopoly, oligopoly, monopolistic competition), production, cost, and revenue.
Consumer behavior is analyzed, including utility maximization and indifference curves.
Firm behavior focuses on profit maximization and cost minimization.

Macroeconomics

Macroeconomics examines the overall performance and behavior of the economy.
It analyzes broad economic aggregates such as inflation, unemployment, economic growth, and international trade.
Key concepts include aggregate demand and supply, fiscal policy, monetary policy, national income accounting, economic growth, business cycles, and inflation.
A focus lies on understanding the factors influencing economic output, employment, and price level.

Types of Economies

Centrally planned economies: A central authority controls production, distribution, and pricing of goods and services.
Market economies: Individuals and firms make most economic decisions.
Mixed economies: A mix of central planning and market mechanisms exists.

Economic Systems

The economic system defines the means by which a society organizes its production and distribution mechanisms.
Traditional economies: Economic decisions are based on custom and tradition.
Command economies: Economic decisions are made by a central authority.
Market economies: Economic decisions are made by individual agents based on supply and demand.

Economic Models

Economic models are simplified representations of reality, used to analyze economic phenomena and predict behavior.
They use assumptions and relationships to illustrate economic principles and implications.
Models help economists understand complex situations and make informed predictions, although they lack the precision of physical models.

Economic Growth

Economic growth refers to an increase in the productive capacity of an economy over time.
It's measured by changes in real GDP (gross domestic product).
Factors driving economic growth include technological advancements, capital accumulation, and labor force growth.

International Trade

International trade involves the exchange of goods and services between countries.
Gains from trade include specialization and comparative advantage in production.
Trade restrictions can include tariffs, quotas, and other policies.
It impacts countries' economic welfare.

Fiscal Policy

Fiscal policy uses government spending and taxation to influence the economy.
It can be used to stimulate or restrain economic activity.
Expansionary fiscal policy increases government spending or reduces taxes to boost demand.
Contractionary fiscal policy decreases government spending or increases taxes to cool down an overheating economy.

Monetary Policy

Monetary policy involves managing the money supply and interest rates to influence the economy.
Central banks are responsible for monetary policy.
Tools include adjusting the reserve requirements for banks, changing interest rates, and open market operations.
Central banks use these tools to control inflation and maintain price stability.

Inflation

Inflation is a sustained rise in the general price level of goods and services.
High inflation can erode purchasing power and create economic instability.
Causes may include excessive money supply growth, rising costs of production, or demand-pull pressures.

Unemployment

Unemployment is the state of being without a job, when actively seeking work.
It can be categorized as frictional, structural, and cyclical.
