Core lesson
GDP Growth Deep Dive
Dissect contributing sectors and expenditure categories to explain growth accelerations and slowdowns.
What you will learn
- Apply growth accounting for capital, labor, and TFP
- Quantify contribution of net exports and inventories
- Connect productivity trends with policy levers
Start with a real question
What does 2% GDP growth actually mean, and who may not feel it?
Core concept
Real GDP removes price changes; nominal GDP does not. Growth per person adjusts for population, while aggregate GDP says nothing about distribution.
Cause→Economic mechanism→Observed outcome
Data connection
Investment shares highlight drivers of growth cycles.

Worked example
Step through it
If nominal GDP grows 6% and prices rise 4%, real growth is approximately 2%. With population growth of 1%, real GDP per person grows about 1%.
Mini practice
- Approximate real growth with 8% nominal growth and 3% inflation.
- Why compare GDP per capita across time?
- Name one cost omitted from GDP.
- Approximately 5%.
- It distinguishes output growth from population growth.
- Examples include environmental damage, unpaid care, or distributional stress.
Common mistake
Assuming GDP growth means every household is better off.
