Core Concepts
Growth accounting·Decomposing growth into labor input, capital input, and total factor productivity. The third term — efficiency and technology — separates rich countries from the rest.
The one-line rule: short-run growth is about demand, long-run growth is about capability. Demand management shapes this year; supply-side capability shapes the next decade.
Three Lenses
| Lens | What to look at | What it answers |
|---|---|---|
| Growth accounting | Labor, capital, efficiency | Input-driven or efficiency-driven? |
| Development stage | Output per head, industry mix | Factor stage or innovation stage? |
| Global position | Trade, investment, technology | Which part of the value chain do you capture? |
Cross-check all three before forming a view. Scale can hide poverty; speed can hide fragility.
How to Apply It
Per capita first
Rankings of total output reflect size; output per person reflects development.
Structure over speed
Decompose growth into consumption, investment and exports before judging quality.
Cycle vs trend
Policy creates cycles; demographics and technology create trends. Do not confuse them.
Calibrate globally
Benchmark against economies of similar size and stage to judge real performance.
What AI Changes
- The digital economy becomes a core growth engine, with data and computing power diffusing like electricity once did
- Growth sources shift from a demographic dividend toward an engineering and efficiency dividend
- Global supply chains trade lowest cost for resilience, accelerating regionalization
- Faster data and commentary make expectations an active variable in the economy
