Macroeconomics: Study of the economy as a whole (e.g., inflation, unemployment, GDP).
Microeconomics: Focuses on individual consumers and businesses (e.g., pricing, supply chains).

Gross Domestic Product (GDP): Total value of goods and services produced in a country.
Unemployment Rate: Percentage of the labor force that is unemployed.
Inflation Rate: Rate at which the general level of prices for goods and services rises.

Classical Economics: Focus on free markets and the idea that markets are self-correcting.
Keynesian Economics: Advocates for government intervention to manage economic cycles.
Monetarism: Emphasizes the role of government in controlling the amount of money in circulation.

Fiscal Policy: Government spending and taxation decisions to influence the economy.

Economics is a dynamic field that helps understand decision-making processes and the functioning of markets. It plays a crucial role in policy-making and understanding global interactions.

Economics involves studying allocation of resources by individuals, businesses, and governments.
Key areas include the production, distribution, and consumption of goods and services.

Scarcity: Limited resources versus unlimited wants lead to choices and trade-offs.
Opportunity Cost: Represents the value of the next best alternative that is not chosen in a decision-making process.
Supply and Demand:
- Demand reflects consumer willingness to buy at various prices.
- Supply indicates the quantity of goods that producers are ready to sell at different prices.
- Equilibrium occurs when the quantity supplied equals the quantity demanded.
Market Structures:
- Perfect Competition: Numerous sellers, identical products, no entry barriers.
- Monopoly: A single seller controls the market, facing high entry barriers.
- Oligopoly: A few sellers dominate the market, with similar or differentiated products.
- Monopolistic Competition: Many sellers offer differentiated products.

Capitalism: Characterized by private ownership and free market operations.
Socialism: Involves government ownership and centralized economic planning.
Mixed Economy: Blends elements of capitalism and socialism for economic management.

Macroeconomics: Studies the economy as a whole, addressing issues like inflation, unemployment, and gross domestic product (GDP).
Microeconomics: Examines individual consumers and businesses, focusing on aspects such as pricing strategies and supply chains.

Gross Domestic Product (GDP): Measures total value of goods and services produced in a nation.
Unemployment Rate: Percentage of the labor force that is currently without work.
Inflation Rate: Indicates the rate at which general prices for goods and services increase.

Classical Economics: Advocates for free markets and views them as self-correcting entities.
Keynesian Economics: Promotes the concept of government intervention to stabilize economic fluctuations.
Monetarism: Emphasizes the government's role in controlling monetary supply and influencing economic stability.
