High School Economics Quiz: Components of GDP (C+I+G+NX)

📚 Quick Study Guide

• 🏠 Consumption (C): Represents spending by households on goods and services. Think groceries, haircuts, and new clothes. It's the biggest part of GDP!
• 🏢 Investment (I): Includes spending by businesses on capital goods (like machinery and equipment), new construction (both residential and commercial), and changes in inventories.
• 🏛️ Government Spending (G): Includes spending by federal, state, and local governments on goods and services. This includes things like infrastructure, national defense, and education. Note: Transfer payments like Social Security are NOT included.
• 🌐 Net Exports (NX): Calculated as exports minus imports. Exports represent goods and services produced domestically and sold abroad, while imports represent goods and services produced abroad and purchased domestically. The formula is: $NX = Exports - Imports$
• ➕ GDP Formula: The expenditure approach to calculating GDP is: $GDP = C + I + G + NX$
• 💡 Important Note: GDP measures the market value of all final goods and services produced within a country's borders during a specific time period.
