Definition of Economics

• Study of how individuals and societies allocate scarce resources.
• Involves decision-making regarding production, distribution, and consumption of goods and services.

Branches of Economics

1. Microeconomics

   • Focuses on individual agents (consumers, firms).
   • Analyzes supply and demand, market structures, and pricing.

2. Macroeconomics

   • Examines the economy as a whole.
   • Discusses national income, GDP, inflation, and unemployment.

Key Concepts

• Scarcity

  • Limited resources vs. unlimited wants.

• Opportunity Cost

  • The cost of the next best alternative foregone when making a decision.

• Supply and Demand

  • Supply: Quantity of a good/services producers are willing to sell.
  • Demand: Quantity consumers are willing to buy.
  • Equilibrium: Point where supply equals demand.

Economic Systems

• Capitalism

  • Private ownership of production.
  • Market-driven economy.

• Socialism

  • Collective ownership or regulation of production.
  • Emphasis on equal distribution of resources.

• Mixed Economy

  • Combination of capitalism and socialism.
  • Both private and public sectors play a role.

Economic Indicators

1. Gross Domestic Product (GDP)

   • Total value of all goods and services produced in a country.

2. Inflation Rate

   • Rate at which the general level of prices for goods and services rises.

3. Unemployment Rate

   • Percentage of the labor force that is jobless and actively seeking employment.

The Role of Government

• Regulation of markets to prevent monopolies.
• Provision of public goods (e.g., national defense, education).
• Fiscal policy: Government spending and tax policies to influence the economy.
• Monetary policy: Control of money supply and interest rates by central banks.

International Economics

• Trade

  • Exchange of goods and services between countries.
  • Benefits include comparative advantage and economies of scale.

• Exchange Rates
