  Economic growth is defined as an increase in the productive capacity of an economy over time, commonly measured by the annual percentage change in real Gross Domestic Product (GDP). It can be illustrated by an outward shift of an economy's Production Possibility Curve (PPC).

  One cause of economic growth is an increase in the quantity and quality of the capital stock. This involves investment in new machinery, technology, and infrastructure such as roads and communication networks. Greater investment increases the economy's productive capacity, allowing more output to be produced with the same amount of labour. This leads to a rightward shift in the Long-Run Aggregate Supply (LRAS) curve, signifying potential growth.

  A second cause is an improvement in the quality of the labour force, or human capital. This is achieved through government or private spending on education, training, and healthcare. A more skilled and healthier workforce is more productive, meaning each worker can produce more output per hour. This increased labour productivity also shifts the LRAS curve to the right, leading to a higher potential output for the economy.

  However, the consequences of economic growth are not always positive. A major benefit is a potential increase in the average standard of living. As real GDP rises, national income increases. This can lead to higher wages for workers and greater profits for firms, allowing households to afford more goods and services. Furthermore, a growing economy generates higher tax revenues for the government, which can be used to improve public services like education and healthcare, further enhancing the quality of life.

  Conversely, economic growth can have significant negative consequences. One major issue is environmental damage. Increased production and consumption can lead to the depletion of non-renewable resources, such as oil and minerals, and create negative externalities like air and water pollution. This environmental degradation can reduce the quality of life for current and future generations, posing a threat to sustainable development. Additionally, the pressure to increase output may lead to a reduction in the quality of life for workers, who may face longer hours, more stress, and less leisure time.

  In conclusion, the consequences of economic growth are not always positive. While it offers the clear potential for improved living standards and lower unemployment, it also carries risks of environmental harm, increased inequality, and a potential decline in non-material aspects of well-being. The overall impact depends heavily on the nature of the growth and the policies implemented by the government to mitigate the negative effects. Therefore, for growth to be truly beneficial, it must be sustainable and inclusive.

  How the marks are awarded

  • M1 — Awarded for a clear and accurate definition of economic growth as an increase in productive capacity or real GDP.
  • M6 — Awarded for explaining investment in capital stock as a cause of economic growth, linking it to increased productive capacity.
  • M3 — Awarded for explaining improvement in the quality of the labour force (human capital) as a cause of growth, linking it to higher productivity.
  • M9 — Awarded for analysis of a positive consequence, explaining how economic growth can lead to an increase in the standard of living through higher incomes and better public services.
  • M11 — Awarded for analysis of a negative consequence, explaining how growth may lead to resource depletion and environmental damage.
  • M12 — Awarded for analysis of another negative consequence, such as the potential reduction in quality of life due to increased stress or less leisure time.
  • M13 — Awarded for offering a valid judgement that the consequences are not always positive, directly addressing the question.
  • M14 — Awarded for a developed conclusion that weighs the positive and negative consequences and considers the conditions under which growth is most beneficial (e.g., sustainability).

  Common mistakes

  • Defining economic growth as an increase in nominal GDP, which fails to account for inflation.
  • Listing causes of growth (e.g., 'technology', 'investment') without explaining the mechanism through which they increase an economy's productive capacity.
  • Providing a one-sided discussion by only focusing on the benefits of growth and ignoring the negative consequences, thus failing to answer the 'always be positive' part of the question.
  • Concluding with a simple 'yes' or 'no' without providing a balanced justification that weighs the different consequences.

  Examiner tip: For 'explain and consider' questions, structure your answer by first defining key terms, then addressing each part of the question separately with balanced arguments before offering a final, justified conclusion.
