Study Notes

Macroeconomics

Definition: The branch of economics that studies the behavior and performance of an economy as a whole.
Key Focus Areas:
- Aggregate output and income
- Total employment and unemployment
- Inflation and deflation
- Economic growth and decline
- Monetary and fiscal policy
Major Models:
- Keynesian Economics: Emphasizes total spending and its effects on output and inflation, advocating for government intervention.
- Classical Economics: Focuses on free markets, supply and demand, and the belief that economies are self-correcting.
- Monetarism: Highlights the role of government in controlling the amount of money in circulation.
Important Indicators:
- Gross Domestic Product (GDP)
- Unemployment Rate
- Inflation Rate
- Balance of Trade

National Income Aggregates

Definition: The total income earned by a nation's residents in the production of goods and services over a specific period.
Key Components:
- Gross Domestic Product (GDP): Total value of all final goods and services produced within a country in a given time frame.
  - Can be calculated using:
    - Production Approach
    - Income Approach
    - Expenditure Approach
- Gross National Product (GNP): GDP plus net income from abroad (income earned by residents from overseas investments minus income earned by foreign residents from domestic investments).
- Net National Product (NNP): GNP minus depreciation (the loss of value of capital goods).
- National Income (NI): Total income earned by a nation's factors of production, including wages, rents, interest, and profits.
Per Capita Income: National Income divided by the total population, indicating average income per person.
Real vs. Nominal Income:
- Nominal Income: Measured in current prices, not adjusted for inflation.
- Real Income: Adjusted for inflation, reflecting the true purchasing power.
Uses of National Income Aggregates:
- Economic analysis and policymaking
- International comparisons of economic performance
- Understanding living standards and quality of life

Macroeconomics

Studies the overall behavior and performance of an entire economy.

- Classical Economics: Emphasizes self-correcting free markets driven by supply and demand.
- Monetarism: Focuses on government control of the money supply to regulate the economy.
Important economic indicators for assessment include:
- Gross Domestic Product (GDP)
- Unemployment Rate

National Income Aggregates

Represents the total income earned by residents in producing goods and services over a defined period.
Key components include:
- Gross Domestic Product (GDP): Total value of final goods and services produced domestically within a specific time.
  - Can be calculated via:
    - Production Approach
    - Income Approach
    - Expenditure Approach
- Gross National Product (GNP): GDP plus net income from abroad, assessing income earned by residents globally versus income earned by foreign residents domestically.
- Net National Product (NNP): GNP minus depreciation, reflecting loss of value in capital goods.
- National Income (NI): Total income derived from factors of production, encompassing wages, rents, interest, and profits.
- Per Capita Income: Calculated by dividing National Income by total population, providing an average income figure per individual.
Distinction between income types:
- Nominal Income: Measured at current prices, unadjusted for inflation.
- Real Income: Adjusted for inflation, offering insights into actual purchasing power.
Uses of national income aggregates include:
- Informing economic analysis and guiding policy decisions.
- Comparing economic performance on an international scale.
- Evaluating living standards and overall quality of life.
