Some important issues

  • Raw materials prices
    • Less-developed countries (LDCs) have claimed exploitation by industrial countries
      • e.g. by buying raw materials cheaply & selling manufactures dear
  • Manufactured exports from LDCs
    • some LDCs have had success in exporting manufactures
    • leading to complaints that jobs are under threat in the industrial countries
  • Trade disputes between industrial countries
    • In some countries , established producers of certain goods are being undercut by efficient modern producers
    • especially from Japan & East Asia
    • should such exports be restricted?

Comparative advantage

  • Trade offers benefits when there are international differences in the opportunity cost of goods.
  • Opportunity cost of a good
    • the quantity of other goods sacrificed to make one more unit of that good
  • The law of comparative advantage
    • states that countries should specialize in producing and exporting the goods that they produce at a lower relative cost than other countries.

The source of comparative advantage

  • An important difference between countries is in factor endowments
  • which will be reflected in different relative factor prices
    • e.g. if the UK has relatively abundant capital but relatively scarce labour as compared with India,
    • then the UK would tend to specialize in capital-intensive goods,
    • and India would tend to specialize in labour-intensive products
  • Comparative advantage may also reflect a relative advantage in technology

Gainers and losers

  • Countries may gain from specialization and trade
    • but not all countries may gain equally
  • Commercial policy
    • is government policy that influences international trade through taxes or subsidies
      • e.g. tariffs
    • or through direct restrictions on imports and exports.

Tariffs

  • The deadweight burden of a tariff suggests that society suffers from this method of restricting trade.
  • This is the case for free trade.
  • Tariffs have fallen substantially under the GATT
    • General Agreement on Tariffs and Trade

The case for tariffs – good arguments

  • Optimal tariff
    • a first-best argument
    • only valid where the importing country is large enough to affect the world price
  • This policy fulfils the principle of targeting
    • which says that the most efficient way to attain a given objective is to use a policy that influences that activity directly.
    • Policies that attain the objective, but also influence other activities are second-best, because they distort those other activities.

The case for tariffs – second-best arguments

  • Way of life
    • an attempt to preserve ‘traditional’ ways
    • a production subsidy would be better
  • Suppressing luxuries
    • an attempt to curb consumption patterns of the rich in a poor society
    • better achieved by a consumption tax
  • Infant industries
    • an attempt to nurture new activities via learning by doing
    • a temporary production subsidy probably better
  • Revenue
    • tariffs raise government revenue
    • but there are better ways
  • Cheap foreign labour
    • a non-argument – denies benefits of comparative advantage

Other commercial policies

  • Although tariff rates have fallen under GATT, there has been a proliferation of other trade restrictions
    • quotas
    • non-tariff barriers
      • administrative regulations that discriminate against foreign goods
    • export subsidies
