Explaining economic growth
What is economic growth?

What is trend growth?

Trend growth refers to the smooth path of long run national output

Measuring the trend rate of growth requires a long-run series of data perhaps of 20-30 years or more in order to calculate average growth rates from peak to peak across different economic cycles

What is economic growth?

What determines the rate of economic growth?

  • Every country is different, each factor will vary in importance for a country at a given point in time
  • Remember too that in our inter-connected globalising world, growth does not happen in isolation. Events in one country and region can have a significant effect on growth prospects in another

Growth Drivers

Here are some of the main determinants of economic growth – they apply for both developing and developed countries although the relative weighting that we might attach to each will depend on the individual circumstances facing each country or region.

  • Growth in physical capital stock - leading to a rise in capital per employee (capital deepening)
  • Growth in the size of the active labour force available for production
  • Growth in the quality of labour (human capital)
  • Technological progress and innovation driving productivity improvements i.e. higher GDP per hour worked
  • Institutions - including maintaining the rule of law, stable demcracy, macro-economic stability
  • Rising demand for goods and services - either led by domestic demand or from external trade

Key exam point:

  • Economic growth is not the same as economic development!
  • Growth can support development but the two are distinct – an important point to make in any A2 macro essay or data response question
