Since running for election, Donald Trump has vowed to ‘put America first’. One of the economic policies he has advocated for achieving this objective is the imposition of tariffs on imports which, according to him, unfairly threaten American jobs. On March 8 2018, he signed orders to impose new tariffs on metal imports. These would be 25% on steel and 10% on aluminium.

His hope is that, by cutting back on imports of steel and aluminium, the tariffs could protect the domestic industries which are facing stiff competition from the EU, South Korea, Brazil, Japan and China. They are also facing competition from Canada and Mexico, but these would probably be exempt provided negotiations on the revision of NAFTA rules goes favourably for the USA.

According to a report by The Trade Partnership (see link below), the tariffs would increase employment in these industries by around 33 000. However, the higher price of these metals would cause job losses in the industries using them. In fact, according to the report, more than five jobs would be lost for every one gained. The CNN Money article linked below gives example of the US industries that will be hit.

But the costs are likely to be much greater than this. Accorinding to the law of comparative advantage, trade is a positive-sum game, with a net gain to all parties engaged in trade. Unless trade restrictions are used to address a specific market distortion in the trade process itself, restricting trade will lead to a net loss in overall benefit to the parties involved.

Clearly there will be loss to steel and aluminium exporters outside the USA. There will also be a net loss to their countries unless these metals had a higher cost of production than in the USA, but were subsidised by governments so that they could be exported profitably.

Already, many countries are talking about retaliation. For example, the EU is considering a ‘reciprocal’ tariff of 25% on cranberries, bourbon and Harley-Davidsons, all produced in politically sensitive US states (see the first The Economist article below). ‘As Jean-Claude Juncker, president of the European Commission, puts it, “We can also do stupid”.’ In fact, this is quite a politically astute move to put pressure on Mr Trump.

But cannot countries appeal to the WTO? Possibly, but this route might take some time. What is more, the USA has attempted to get around WTO rules by justifying the tariffs on ‘national security’ grounds – something allowed under Article XXI of WTO rules, provided it can be justified. This could possibly deter countries from retaliating, but it is probably unlikely. In the current climate, there seems to be a growing mood for flouting, or at least loosely interpreting, WTO rules.




  1. Explain how, by countries specialising in goods in which they have a comparative advantage, all countries can gain.
  2. Can tariffs or other trade restrictions ever be justified? Explain.
  3. Is there any economic justification for the US tariffs of 25% on steel and 10% on aluminium?
  4. Can putting tariffs on US imports be justified by countries whose steel and/or aluminium industires are faced with US tariffs?
  5. Can trade wars be won? Explain.

A deal has just been signed between 26 African nations to form a new free trade area, the Tripartite Free Trade Area (TFTA). The countries have a population of 625 million (56% of Africa’s total) and a GDP of $1.6 trillion (63% of Africa’s total). The deal effectively combines three existing free trade areas: the Common Market for Eastern and Southern Africa, the Southern African Development Community and the East African Community.

Although the deal has been signed by the nations’ leaders, it still needs parliamentary approval from each of the countries. It is hoped that this will be achieved by 2017. If it is, it will mark a major step forward in encouraging intra-African trade.

The deal will involve the removal of trade barriers on most goods and lead to a reduction in overall tariffs by more than 50%. The expectation of the leaders is that this will generate $1 trillion worth of economic activity across the 26 countries through a process of trade creation, investment, increased competition and the encouragement of infrastructure development. But given the current poor state of infrastructure and the lack of manufacturing capacity in many of the countries, the agreement will also encourage co-operation to promote co-ordinated industrial and infrastructure development.

Up to now, the development of intra-African trade has been relatively slow because of poor road and rail networks and a high average protection rate – 8.7% on exports to other African countries compared with 2.5% on exports to non-African countries. As a result, intra-African trade currently accounts for just 12% of total African trade. It is hoped that the development of TFTA will result in this rising to over 30%.

Much of the gains will come from economies of scale. As Kenyan academic Calestous Juma says:

“By having larger markets, it signals the possibility of being able to manufacture products at a scale that is cost-effective. For example, where you need large-scale investments like $200m to create a pharmaceutical factory, you couldn’t do that if you were only selling the products in one country.”

The question is whether the agreement signed on the 10 June will lead to the member countries fully taking advantage of the opportunities for trade creation. Agreeing on a deal is one thing; having genuinely free trade and investing in infrastructure and new efficient industries is another.

  1. Distinguish between a free trade area, a customs union and a common market.
  2. What does the law of comparative advantage imply about the gains from forming a free trade area?
  3. Distinguish between trade creation and trade diversion.
  4. Why is it likely that there will be considerable trade creation from TFTA? Would there be any trade diversion?
  5. Why are small countries with a relatively low level of economic development likely to experience more trade creation than larger, richer ones?
  6. What barriers might remain in trade between the TFTA countries?
  7. Why might smaller, less developed members of TFTA be worried about the removal of trade barriers?
  8. Why might concentrating on developing local capacity, rather than just lowering tariffs, be a more effective way of developing intra-African trade
  9. What ‘informal’ barriers to trade exist in many African countries?
  10. Why is it that ‘Ordinary Africans are most probably not holding their breath’ about the gains from TFTA?

The east African countries of Kenya, Tanzania, Uganda, Burundi and Rwanda have been operating with a common external tariff for some time. The East African Community (EAC), as it is known, came into force in 2000. Initially it had just three members, Kenya, Tanzania and Uganda; the other two countries joined in 2007. As the Community’s site says:

The EAC aims at widening and deepening co-operation among the Partner States in, among others, political, economic and social fields for their mutual benefit. To this extent the EAC countries established a Customs Union in 2005 and are working towards the establishment of a Common Market in 2010, subsequently a Monetary Union by 2012 and ultimately a Political Federation of the East African States.

This Common Market came into force on 1 July 2010, with free movement of labour being instituted between the five countries. The plan is also to do away with all internal barriers to trade, although it may take up to five years before this is completed.

The following articles and videos look at this significant opening up of trade in east Africa and at people’s reactions to it. Will all five countries gain equally? Or will some gain at the others’ expense?
