2.5.1 Causes of economic growth Flashcards
Short-run economic growth
(Actual growth)
Occurs when there is an increase in the quantity of goods/services produced in an economy over a given period of time.
It is measured by the percentage change in real national output (real GDP).
Long-run economic growth
(potential growth)
Caused by an increase in the capacity (productive capacity) of the economy.
This usually happens due to a rise in the quality/quantity of inputs (factors of production) – for example, more advanced machinery or a more highly skilled labour force.
How is short-run growth shown on a PPF?
Short run growth is shown by a movement from point A to point B, whilst the PPF itself remains fixed.
How is long-run growth shown on a PPF?
Long run growth is shown by a shift outwards of the PPF. (An increase in the capacity of an economy).
Export-led economic growth
Growth that occurs as a result of an increase in the sale of goods/services to foreign countries.
- Net exports is a component of aggregate demand (AD).
- For many developing countries, their exports represent a high percentage of the annual AD and gross domestic product (GDP). When the value of the exports rise, the real GDP rises significantly - and vice versa
Supply side causes of economic growth
- Increased investment
- Higher labour productivity
-Increase in labour force - Improved technology
