A2 Model: using comparative advantage theory in exam answers

Evaluate the benefits to an African country of increased trade with BRICS? (12 marks)

6 mark response

Increased trade links between an African and BRIC country, such as China, could result in increased economic growth for the African economy as a result of comparative advantage theory.  (1 mark for growth) This may occur as an African economy can identify its ‘ability to produce a good at a lower opportunity cost than China’s economy ie an African
country has a comparative advantage in production of a commodity if it has to forego the production of fewer other products such as manufactured items in order to make more crops. The resulting gains in productive efficiency resulting from specialising in growing crops and trading at a mutually beneficial exchange rate will result in catch up growth for the African economy and the ability to operate outside its PPF i.e. increased trend growth. (Extensive Analysis 2 marks)

However if the crop exported has a highly income elastic demand and China goes into recession growth may be stunted (2e). The developing country may become over-reliant on the crop - so risks harvest failure  - supply side shocks causes recession and absolute poverty. (1e). The developing country's exports lacks added value and faces global competition so poor terms of trade (2e).
Also other potential evaluative marks:
ignores transport costs (ie it may be cheaper to produce sheep in the UK rather than pay for
shipping from New Zealand (NZ))
• ignores external costs of production (eg environmental degradation)
• ignores gains from economies of scale
• assumes factors of production can easily be switched from producing one good to producing
another (which they can’t)
• assumes perfect knowledge (which doesn’t exist)
• reduces self-sufficiency.


To do - Produce a slimmed down version for discussing gains to the UK of staying in the EU?

AS Model answer: Examine the impact of a cut in interest rates


Using an AD/AS diagram examine the impact of a cut in interest rates
A decrease in interest rates may cause a fall in the cost of borrowing for many consumers and firms across the UK, as well as discourage savings (1m); this may result in a rise in Consumption and Investment (1 mark) causing AD to shift RIGHT (1m). The consequence of this is some firms may expand as they become more profitable when faced with more customers and orders for new technology from other firms, (1mark) resulting in RECOVERY, a quarterly rise in Real GDP after a recession (Y1-Y2) (1m)

However the size of the recovery may not be that significant if the fall in interest rates is not that SIGNIFICANT  (2e) or long lasting as demand pull inflationary pressures (P1-P2) rise forcing the Bank of England to increase interest rates (MAGNITUDE/SCALE)(2e).

AS Model example: Examine the impact of a rise in the price of oil

Using and AS/AD diagram examine the impact of a rise in the price of oil

A increase in the price of oil may cause a rise in the cost of production for many firms across the UK as petrol, energy bills and plastics increase (1m) causing AS to shift LEFT (1m). The consequence of this is some firms may close as they become less profitable causing recession, a two consecutive quarterly fall in Real GDP  (Y1-Y2) (1m) Some firms may pass the increase in costs on to consumers so overall in general there might be a rise in cost push inflationary pressures. (1m)

However the size of the oil price rise may not be that significant  SIGNIFICANT  (2e) or may not last for long as eventually oil prices fall (TIME)(2e). Also the UK government may do something to help businesses cope with the rise in price for example by not increasing tax on petrol or cutting energy bill taxes on businesses. (2e)

AS Modelled Answer: Evaluate the use of a supply side policies to achieve economic growth.

Using an AS/AD diagram evaluate the use of a supply side policies to achieve economic growth.

A decrease in the National Minimum wage may cause a fall in the cost of production for many firms across the UK (1m) causing AS to shift RIGHT (1m). The consequence of this is some firms may expand as they become more profitable causing recovery, a quarterly rise in Real GDP after a recession (Y1-Y2) (1m) In the long term firms may relocate to the UK if they believe that the UK is a low cost economy, shifting PPF outwards i.e increasing potential output/trend growth. (1m)

However the size of the recovery may not be that significant if the fall in the NMW is not that SIGNIFICANT  (2e) or does not affect many people (MAGNITUDE/SCALE)(2e). also workers may become poor, demotivated, leave the labour market or even the UK so  UK productivity falls and national output falls.
