GDP = C + I + G + NX: The expenditure approach to measuring GDP sums four components: Consumer spending, Investment, Government spending, and Net Exports.
Consumption (C): ~68% of US GDP. Durable goods (cars), nondurable goods (food), and services (healthcare, entertainment).
Investment (I): ~18%. Business spending on capital, residential construction, and inventory changes. NOT stocks/bonds.
Net Exports (NX): Exports − Imports. Usually negative for the US (trade deficit), meaning NX reduces GDP.
