Study Notes

Macroeconomics Overview

Macroeconomics studies a country's entire economy, unlike microeconomics that focuses on individual markets.
It analyzes decisions of consumers, producers, government, and foreign entities impacting a nation's economy.

Circular Flow Model

Illustrates money flow within an economy, simplified to households and firms.
In the resource market, households provide resources (land, labor, capital, entrepreneurship) to firms, receiving payments (rent, wages, interest, profit).
In the product market, households spend income on goods and services from firms.
Households are resource suppliers and product demanders, while firms are product suppliers and resource demanders.
Output, income, and spending are equal within the economy.
Complex models include leakages (savings, taxes, imports) and injections (investment, government spending, exports).
Leakages exceeding injections cause a shrinking economy; the reverse leads to growth.

Business Cycle

Shows short-term fluctuations in economic output around long-term growth trends.
Expansions feature low unemployment, rising prices, and increasing output.
Contractions exhibit rising unemployment, slowing or declining output.
A contraction lasting at least six months is a recession.
The economy aims to maintain relatively consistent growth close to its potential.

GDP Measurement

Gross Domestic Product (GDP) measures a country's economic activity.
GDP is calculated via income, output, and spending approaches (often using the expenditure method).
Expenditure approach: GDP = C + I + G + Xn (Consumption + Investment + Government spending + Net exports).
Intermediate goods are excluded to avoid double-counting.
Only goods and services produced within a country are included.
Illegal activities, non-produced transactions (like stocks/bonds), and transfer payments (e.g., social security) are not factored in.
Homemade goods have no market value and aren't included.

Nominal vs. Real GDP

Nominal GDP uses current prices, and real GDP adjusts for inflation.
Real GDP provides a more accurate measure of economic growth compared to nominal values.
A percentage change formula is used to calculate economic growth based on GDP changes.
GDP deflator formula can get real GDP values by adjusting nominal values for inflation.
