11.1 The Gains from Trade

Can international trade make people better off?
 

Specialisation as basis for trade

Just as specialisation can bring benefits at a firm level (through economies of scale) likewise this applies at the level of overall county production where similar economies can be gained from specialisation.
 

The law of absolute advantage

This is obvious enough. Imagine a simple world with two countries (A and B) and two products (say food and cars).

If A can produce food more efficiently than B and B in turn cars more efficiently than A, then A should specialise in food production and B in cars with trade in both products taking place between them).
 

The law of comparative advantage

This is even more important (though less obvious).

Even - in the previous example - if A was more efficient at producing both food and cars than B, then specialisation should still take place on the basis of what each country is relatively most efficient.

For example if A was three times as efficient at producing food but only twice as efficient at producing cars, then B, then A has a comparative advantage in food, while B has a comparative advantage in cars.

So A therefore should specialise in food and B in cars (with trade taking place between them).

Perhaps one could appreciate this with a simple – related – illustration. Imagine two students sharing a flat with one student better at both cooking and flat maintenance.

Here responsibilities should be assigned on the basis of comparative advantage. Thus if the first student is a super cook and the other hopeless in this regard and the second reasonably good at maintenance (though not as good as the first), then it makes sense than the first student should concentrate on cooking with the second doing the maintenance.

The importance of the law of comparative advantage is that it creates a case for involvement in trade of all countries (whether developed or undeveloped).
 

Limits to specialisation

However it does not make sense – even in economic terms – for countries to attain complete specialisation with respect to some goods and services.

For example If Ireland tried to achieve complete specialisation with respect to agriculture, eventually it would become highly inefficient as people with no talent for or interest in farming would have to be employed.
 

The terms of trade

The law of comparative advantage suggests that overall production will increase through specialisation. However it does not state how gains should be distributed between nations. This is where terms of trade are important

It is defined as

Average price of exports
Average price of imports
 
 

Other reasons for gains from trade
 

Decreasing costs

Economies of scale can be achieved through specialisation thus increasing efficenecy. Indeed this is one of the major reasons for the formation of the EU with its large internal market (free of trading barriers).
 

Differences in demand

Even if there was no comparative advantage (or cost difference) if there are differences in demand for a product in two countries it makes sense to specialise.
 

Increased competition

Competition from imports can stimulate greater competition to the benefit of consumers. We are seeing this now in the retail trade in Ireland since the arrival of Lidl and Aldi.
 

Trade as engine of growth

Trade opens up the possibility of an economy growing much more rapidly trough high export growth.
 

Non-economic advantages

There can be significant political cultural and social advantages to trade. So for example the formation of the EU was seen primarily as a means of preventing the possibility of another major war in Europe.
 
 

Methods  of restricting trade
 

Tariffs (customs duties)

-   tax or levy on imports; has a number of effects on consumer, producer, government and distribution

Quotas

-   quantitative limitations on imports
 

Exchange Controls

-   limits on taking foreign currency out of country
 

Export Taxes
 

Subsidies
 

Administrative Barriers
 

Procurement Policies
 

To protect declining industries
 

Non-economic arguments

-   to preserve the production of a wide range of products in case of war
 

-   refusal to trade with certain countries because of political disagreements
 

-   to preserve a traditional way of life
 

-   to maintain as diverse a society as possible
 
 

Arguments in favour of restricting trade
 

The infant industry argument

-   industries may need to be protected the enable them to grow sufficiently to achieve economies of
    scale
 

To prevent "dumping" and other unfair trade practices

 -  dumping refers to below cost selling
 

To prevent the establishment of a foreign-based monopoly
 

To reduce reliance on goods with little dynamic potential
 

To spread the risks of fluctuating markets
 

To reduce the influence of trade on consumer tastes
 

To prevent the importation of harmful goods
 

To take account of externalities
 

The exploitation of monopoly power
 

To protect declining industries
 

Non-economic arguments

-   to preserve the production of a wide range of products in case of war

-   refusal to trade with certain countries because of political disagreements

-   to preserve a traditional way of life

-   to maintain as diverse a society as possible
 
 

Problem with protection
 

There may be better ways of helping industry

World multiplier effects

- as one country's imports represents another country's exports reducing imports ultimately reduces export opportunities
 

Retaliation

-  generally when a country imposes restrictions it imposes retaliatory measures
 

Protection may encourage inefficiency with respect to production
 

Bureaucracy

- protectionism can lead to large administrative costs
 

Types of Trading Agreements
 

  • Free Trade Area
        - where countries remove tariffs and quotas against each other but are free to restrict imports
           from non-member countries
 
  • Customs Union
        - a free trade area where countries adopt a common external tariff (and quotas) with respect to
           non-members
 
  • Common Market
        - where member countries operate a single market, implying similar taxes, similar laws and
 
        - regulations, free movement of labour capital and materials and common policies in different
          economic areas
 
  •  Economic and Monetary Union (EMU)
        -  fixed exchange rates leading to common currency

        - common Central Bank

        - common macroeconomic policies
 

  • Economic and Political Union
        - common defence policy

        - centralised decision-making
 

Direct Effects of Customs Union
 

Trade Creation

- where consumption shifts from high cost to low cost producer
 

Trade Diversion

-  where consumption shifts from lower cost to high cost producer
 

Advantages of Customs Union

- increased market size

- external economies of scale

- increased bargaining power of whole customs union

- increased competition between member countries
 

Disadvantages of Customs Union

- loss of sovereignty

- possible diseconomies of scale

-  increased bureaucracy

-  uneven effects throughout union
 

• Examples of Customs Union

- EU, NAFTA, ASEAN etc
 
 

The European Union
 

No. of countries

- presently 15 members Germany, France, Britain, Ireland, Italy, Spain, The Netherlands, Belgium, Luxembourg, Portugal, Denmark, Greece, Sweden, Austria, Finland
 

Applicant countries

- to join May 2004; Poland, Hungary, The Czech Republic, Estonia, Latvia, Cyprus,
Malta, Slovakia, Slovenia, Lithuania
 

Applicant countries - to join 2007; Bulgaria and Romania (Turkey undecided)
 
 

From Customs Union to Common Market
 

Common Agricultural Policy

-   artificial high prices set for farm food
 

Regional Policy

-   EU regional policy provides grants to firms and local authorities in depressed regions of the union
 

Competition Policy

- EU controls restrictive policies and monopoly Harmonisation of Taxation

- this has been carried out with respect to VAT
