• Unemployment Rate: Percentage of the labor force that is jobless and actively seeking employment.
• Inflation Rate: Rate at which the general level of prices for goods and services is rising.

6. Market Structures

• Perfect Competition: Many firms, identical products, free entry and exit.
• Monopoly: Single firm controls the entire market, unique product, high barriers to entry.
• Oligopoly: Few firms dominate the market, products may be identical or differentiated.

7. Role of Government
