Macroeconomics looks at the economy as a whole, analyzing aggregate variables such as
national income, inflation, unemployment, and economic growth. It focuses on large-scale
economic factors and how policies (monetary and fiscal) can influence overall economic
performance.
1. National Income Accounting
National income accounting is a framework used by economists to measure the economic
performance of a country. It includes:
Gross Domestic Product (GDP): Represents the total market value of all goods and services
produced in a country in a specific period. It helps to understand the size and health of an
economy.
Nominal GDP: Measures economic output at current prices without adjusting for inflation.
Real GDP: Adjusts for inflation to reflect the true value of goods and services.
GDP Deflator: Measures the price change of goods and services included in GDP over time.
Gross National Product (GNP): Expands on GDP by including income earned by residents from
abroad, minus income earned by foreigners within the country.
Net National Product (NNP): Accounts for depreciation of capital, adjusting GNP to reflect the
loss of value due to wear and tear.
Personal Income (PI): The total income received by individuals, including wages, interest, and
profits, before taxes.
Disposable Income (DI): The amount of money left after taxes and government transfers,
available for consumption and saving.

interconnected. Each term would branch out showing their relationships with consumption,
savings, and government policies.
2. Inflation
Inflation refers to the rise in the general price level of goods and services over time, decreasing
the purchasing power of money.
, Demand-pull inflation: Occurs when demand for goods and services exceeds supply, driving
prices up.
Cost-push inflation: Happens when the cost of production (e.g., wages, raw materials)
increases, leading to higher prices.
CPI (Consumer Price Index): A key indicator used to measure inflation by tracking the price
change of a basket of consumer goods over time.

goods is tracked over time, and how the percentage change is calculated to represent inflation.
3. Unemployment
Unemployment occurs when people who are capable of working, are not actively working.
Frictional Unemployment: Short-term unemployment as people transition between jobs.
Structural Unemployment: Long-term unemployment due to changes in the economy or
mismatches between worker skills and available jobs.
Cyclical Unemployment: Caused by economic downturns (recessions) where there is insufficient
demand for goods and services.

unemployment types and show how they impact the economy.
4. Fiscal Policy
Fiscal policy refers to government decisions regarding taxation and spending to influence the
economy.
Government Spending: An increase in government expenditure boosts demand for goods and
services, stimulating economic growth.
Taxation: A rise in taxes reduces disposable income and consumer spending, thus slowing
down the economy.

GDP and employment levels.
