  • Capitalism: An economic system characterized by private ownership and free markets.
  • Socialism: An economic system where the means of production are owned and regulated by the state.
  • Mixed Economy: Combines elements of capitalism and socialism.

  • Gross Domestic Product (GDP): The total value of all goods and services produced in a country over a specific period.
  • Unemployment Rate: The percentage of the labor force that is jobless and actively seeking employment.
  • Inflation Rate: The rate at which the general level of prices for goods and services rises.

• Key Theories:

  • Classical Economics: Advocates for free markets and minimal government intervention.
  • Keynesian Economics: Argues that active government intervention is necessary to manage economic cycles.
  • Monetarism: Emphasizes the role of government in controlling the amount of money in circulation.

• Market Structures:

  • Perfect Competition: Many firms, identical products, and free entry and exit.
  • Monopoly: A single firm dominates the market with no close substitutes.
  • Oligopoly: A few firms control the market, often with interdependent pricing.

• Public Policy:

  • Fiscal Policy: Government adjustments in spending levels and tax rates to influence the economy.

• Market Equilibrium occurs when the quantity supplied equals the quantity demanded.
• Elasticity measures the responsiveness of demand or supply to price changes.
• Opportunity Cost represents the value of the next best alternative that is sacrificed when a choice is made.

Economic Systems

• Capitalism is defined by private ownership and the operation of free markets.
• Socialism involves state ownership and regulation of production means.

• Unemployment Rate indicates the percentage of the labor force that is unemployed and seeking work.
• Inflation Rate represents the pace at which prices for goods and services increase over time.

Key Theories

• Classical Economics supports free market principles with limited government intervention.
• Keynesian Economics promotes the necessity of government intervention to manage economic fluctuations.
• Monetarism stresses the government’s role in regulating money supply to control inflation.

Market Structures

• Perfect Competition features numerous firms offering identical products with no barriers to entry and exit.
• Monopoly exists when a single firm controls the entire market with no close substitute products.
• Oligopoly consists of a few firms that dominate the market, often leading to price interdependence among them.

Public Policy

• Fiscal Policy involves government strategies related to spending and tax adjustments to steer economic performance.

• Trade Balance measures the difference between a country's exports and imports, indicating economic health.
• Exchange Rates define the conversion value between different currencies.
• Globalization refers to the increasing interconnectedness of global economies through trade and investment activities.
