- Aggregate output: total amount of output produced and supplied in the economy in a given
period
- Nominal GDP ($Y): the sum of the quantities of final goods produced times their current price
- Real GDP (Y): the sum of quantities of final goods times constant (not current) prices
- Example:
Nominal GDP in 2011: 10 × 20,000 = 200,000 Real GDP in 2011: 10 × 24,000 = 240,000
Nominal GDP in 2012: 12 × 24,000 = 240,000 Real GDP in 2012: 12 × 24,000 = 288,000
Nominal GDP in 2013: 13 × 26,000 = 260,000 Real GDP in 2013: 13 × 24,000 = 312,000
GDP
- GDP per capita =
Population
- Labor force (L): Employment (N) + Unemployment (U)
Labor force
- Labor force participation rate =
working age population
Employed
- Employment rate =
working age population
Enemployed U
- Unemployment rate = or u=
Labor force L
- Inflation is a sustained rise in the general level of prices – the price level.
- Deflation is a sustained decline in the price level.
- Consumer Price Index (CPI) is a measure of the cost of living
- Pure inflation is proportional increase in all prices and wages.
Okun’s law: measures the relationship between the unemployment rate and output
growth rate. The relationship is a negative relationship.
Philip’s curve: measures the relationship between the unemployment rate and
inflation rate. The relationship is a negative relationship.
