Study Notes
Macroeconomic economic activity involves understanding how national income accounting measures the economy's output and performance. It includes concepts like GDP, GNI, and the business cycle.
- National Income Accounting — the process of measuring an economy's national income or output. Example: Used to assess economic performance and set policy goals.
- Gross Domestic Product (GDP) — the market value of all final goods and services produced within a country. Example: Calculated using the expenditure approach as C + I + G + (X-M).
- Gross National Income (GNI) — the total income received by residents of a country, including net factor income from abroad. Example: GNI = GDP + (income earned from abroad - income paid abroad).
- Real GDP — GDP adjusted for inflation, reflecting the value of goods and services at constant prices. Example: Calculated using a GDP deflator.
- Business Cycle — short-term fluctuations in real GDP around a long-term growth trend. Example: Includes stages like expansion, peak, contraction, and trough.
