  1. Absolute and Comparative AdvantageA2 Economics

  2. Aims and Objectives Aim: • Understand the theory of absolute and comparative advantage. Objectives: • Define the theory of absolute and comparative advantage. • Analyse the effects of specialisation • Evaluate the case for free trade

  3. Starter • What is the UK current account? • Do we have a deficit on the CA? Have we always had a deficit on the CA? • Is the UK trade deficit important?

  4. Absolute Advantage China & Russia

  5. Absolute Advantage • Two countries • Produce just two commodities – guns and oil. • Each country has 10 units of resources • Using all resources they can produce the output shown:

  6. Absolute Advantage • Trading (Production) possibility diagram: • China has an absolute advantage in the production of both guns and oil. • Absolute Advantage: where a country using a given resource input is able to produce more than other countries with the same input. 400 300 China 200 Russia 100 0 100 200 300 400

  7. Self Sufficiency • If each country was self-sufficient and did not trade (closed economy) the output would be shown as follows:

  8. Comparative Advantage China & Russia

  9. Comparative Advantage • While Russia has an absolute disadvantage compared to China, it still benefits countries to specialise in the production of a good or service. • Theoretical basis for free trade is comparative advantage. • Comparative Advantage: where a country can produce a good with a lower input cost than other countries. Therefore global resources can be allocated more efficiently.

  10. Comparative Advantage • Opportunity costs in each country: 1 Oil Barrel = 1 Gun 1 Gun = 1 Oil Barrel 1 Oil Barrel = 0.5 Gun 1 Gun = 2 Oil Barrel These op.cost ratios show Russia has a comparative adv. in oil, as to produce an extra unit of oil it only has to give up half a gun compared to 1 gun for China.

  11. Comparative Advantage • Opportunity costs in each country: 1 Oil Barrel = 1 Gun 1 Gun = 1 Oil Barrel 1 Oil Barrel = 0.5 Gun 1 Gun = 2 Oil Barrels However, China has a comparative advantage in guns as to produce an extra gun it only has to give up 1 unit of oil, compared to 2 units for Russia.

  12. Comparative Advantage Differences in comparative adv. and op. cost give rise to international trade, where countries specialise in the area where they have the greatest comparative adv. SPECIALISATION

  13. However, the output of oil has fallen from 360 to 320. Partial specialisation can be used to rectify this…..

  14. Comparative Advantage Original Economies Output Partially Specialised Economies Output

  15. Therefore, total output of oil has increased from 360 to 380 whilst the production of guns has also increased from 280 to 340. International trade has led to an increase in total supply of both products and economic welfare will increase in both countries.

  16. Plenary Define and give examples of comparative and absolute advantage. Should specific countries specialise in the sole production of just a few goods, for which they possess a comparative advantage?
