5. Market Structures

   • Perfect Competition: Many firms, identical products, easy entry and exit.
   • Monopolistic Competition: Many firms, differentiated products.
   • Oligopoly: Few firms dominate the market, potential for collusion.
   • Monopoly: Single firm controls the entire market.

6. Economic Indicators

   • GDP (Gross Domestic Product): Measures economic output and growth.
   • Unemployment Rate: Percentage of the labor force that is jobless.
   • Inflation Rate: Rate at which the general level of prices for goods and services rises.

7. Fiscal and Monetary Policy

   • Fiscal Policy: Government spending and tax policies to influence the economy.
   • Monetary Policy: Central bank actions that manage the money supply and interest rates.

8. International Economics

   • Trade: Importing and exporting goods and services.
   • Exchange Rates: Value of one currency in relation to another.
   • Balance of Payments: Record of all economic transactions between residents of a country and the rest of the world.

Key Theories

• Classical Economics: Emphasizes self-regulating markets and the role of supply-side factors.
• Keynesian Economics: Advocates for active government intervention to manage economic cycles.
