Commonly confused

• Gross investment vs Net investment

  Gross investment: all new capital produced. Net investment: gross investment minus depreciation.

• Human capital vs Labour

  Human capital: the quality of labour: the skills and training embodied in the worker. Labour: the quantity of effort supplied.

• Actual growth vs Potential growth

  Actual growth: a rise in output produced, which can occur inside the frontier. Potential growth: a rise in capacity, shown only by the frontier moving out.

Questions from this topic

Each one with the model answer underneath.

1. 1

   Name the four factors of production and give the reward earned by each.

   Model answer

   Land earns rent, labour earns wages, capital earns interest and enterprise earns profit. Land covers all natural resources, labour is human physical and mental effort, capital is any man-made asset used to produce other goods, and enterprise is the willingness to organise the other three factors and to bear the risk of doing so.

2. 2

   Why do economists count a fish stock, a coal seam and a river as the same factor of production?

   Model answer

   All three are gifts of nature rather than things people have manufactured, so all three are classified as land. The factor land is not limited to the ground itself: it covers every natural resource used in production, including minerals, forests, fisheries, water and the climate.

3. 3

   Distinguish between renewable and non-renewable land, and explain why the distinction matters for production.

   Model answer

   Renewable land regenerates over time if it is not over-used, such as timber, fish stocks or wind, while non-renewable land exists in a fixed stock that is depleted by use, such as oil, gas and metal ores. The distinction matters because non-renewable resources impose a limit on how long current production can be sustained, and because over-harvesting a renewable resource can turn it into an effectively non-renewable one.

4. 4

   A firm buys a delivery van, a warehouse and a computer system. Explain what these three items have in common in economic terms.

   Model answer

   All three are capital, because each is a man-made asset that is not consumed directly but is used to produce goods and services over a long period. Capital is defined by its role in production rather than by what it is made of, so buildings, machinery, vehicles, tools and infrastructure are all capital.

5. 5

   Why is money not counted as capital in the economic sense?

   Model answer

   Money is a claim on resources, not a productive resource in itself: a stack of banknotes cannot make anything. Capital in economics means physical assets such as machines, buildings and equipment that raise the output a country can produce. Money matters because it can be used to buy capital, but the productive contribution comes from the machine, not the cash.

6. 6

   What is human capital, and why can two workforces of the same size have very different productive potential?

   Model answer

   Human capital is the stock of skills, education, training, experience and health embodied in workers. Two workforces of identical size can differ enormously in output because one may be better educated, better trained and healthier, so each hour of labour produces more. This is why spending on schooling and training raises an economy's productive capacity even when the number of workers is unchanged.
