With the Conservatives having lost their majority in Parliament in the recent UK election, there is renewed discussion of the form that Brexit might take. EU states are members of the single market and the customs union. A ‘hard Brexit’ involves leaving both and this was the government’s stance prior to the election. But there is now talk of a softer Brexit, which might mean retaining membership of the single market and/or customs union.
The single market
Belonging to the single market means accepting the free movement of goods, services, capital and labour. It also involves tariff-free trade within the single market and adopting a common set of rules and regulations over trade, product standards, safety, packaging, etc., with disputes settled by the European Court of Justice. Membership of the single market involves paying budgetary contributions. Norway and Iceland are members of the single market.
The single market brings huge benefits from free trade with no administrative barriers from customs checks and paperwork. But it would probably prove impossible to negotiate remaining in the single market with an opt out on free movement of labour. Controlling immigration from EU countries was a key part of the Leave campaign.
The customs union
This involves all EU countries adopting the same tariffs (customs duties) on imports from outside the EU. These tariffs are negotiated by the European Commission with non-EU countries
on a country-by-country basis. Goods imported from outside the EU are charged tariffs in the country of import and can then be sold freely around the EU with no further tariffs.
Remaining a member of the customs union would allow the UK to continue trading freely in the EU, subject to meeting various non-tariff regulations. It would also allow free ‘borderless’ trade between Northern Ireland and the Republic of Ireland. However, being a member of the customs union would prevent the UK from negotiating separate trade deals with non-EU countries. The ability to negotiate such deals has been argued to be one of the main benefits of leaving the EU.
Free(r) trade area
The UK could negotiate a trade deal with the EU. But it is highly unlikely that such a deal could be in place by March 2019, the date when the UK is scheduled to leave the EU. At that point, trade barriers would be imposed, including between the two parts of the island of Ireland. Such deals are very complex, especially in the area of services, which are the largest category of UK exports. Negotiating tariff-free or reduced-tariff trade is only a small part of the problem; the biggest part involves negotiating product standards, regulations and other non-tariff barriers.
All the above options thus involve serious problems and the government will be pushed from various sides, not least within the Conservative Party, for different degrees of ‘softness’ or ‘hardness’ of Brexit. What is more, the pressure from business for free trade with the EU is likely to grow. Brexit may mean Brexit, but just what form it will take is very unclear.

Questions
- Explain the trading agreement between Norway and the EU.
- How does the Norwegian arrangement with the EU differ from the Turkish one?
- What are meant by the terms ‘hard Brexit’ and ‘soft Brexit’?
- How does a customs union differ from a free trade area?
- Is it possible to have (a) a customs union without a single market; (b) a single market without a customs union?
- To what extent is it in the EU’s interests to negotiate a deal with the UK which lets it maintain access to the customs union without having free movement of labour?
- The EU insists that talks about future trading arrangements between the UK and the EU can take place only after sufficient progress has been made on the terms of the ‘divorce’. What elements are included in the divorce terms?
- If agreement is not reached by 29 March 2019, what happens and what would be the consequences?
- Will a hung parliament, or at least a government supported by the DUP on a confidence and supply basis, make it more or less likely that there will be a hard Brexit?
- For what reasons may the EU favour (a) a hard Brexit; (b) a soft Brexit?
In the light of the Brexit vote and the government’s position that the UK will leave the single market and customs union, there has been much discussion of the need for the UK to achieve trade deals. Indeed, a UK-US trade deal was one of the key issues on Theresa May’s agenda when she met Donald Trump just a week after his inauguration.
But what forms can a trade deal take? What does achieving one entail? What are likely to be the various effects on different industries – who will be the winners and losers? And what role does comparative advantage play? The articles below examine these questions.
Given that up until Brexit, the UK already has free trade with the rest of the EU, there is a lot to lose if barriers are erected when the UK leaves. In the meantime, it is vital to start negotiating new trade deals, a process that can be extremely difficult and time-consuming.
A far as new trade arrangements with the EU are concerned, these cannot be agreed until after the UK leaves the EU, in approximately two years’ time, although the government is keen that preliminary discussions take place as soon as Article 50 is triggered, which the government plans to do by the end of March.

Questions
- What elements would be included in a UK-US trade deal?
- Explain the gains from trade that can result from exploiting comparative advantage.
- Explain the statement in the article that allowing trade to be determined by comparative advantage is ‘often politically unacceptable, as governments generally look to protect jobs and tax revenues, as well as to protect activities that fund innovation’.
- Why is it difficult to work out in advance the likely effects on trade of a trade deal?
- What would be the benefits and costs to the UK of allowing all countries’ imports into the UK tariff free?
- What are meant by ‘trade creation’ and ‘trade diversion’? What determines the extent to which a trade deal will result in trade creation or trade diversion?
Theresa May has said that the UK will quit the EU single market and seek to negotiate new trade deals, both with the EU and with other countries. As she said, “What I am proposing cannot mean membership of the single market.” It would also mean leaving the customs union, which sets common external tariffs for goods imported into the EU.
The single market guarantees free movement of goods, services, labour and capital between EU members. There are no internal tariffs and common rules and regulations concerning products, production and trade. By leaving the single market, the UK will be able to restrict immigration from EU countries, as it is currently allowed to do from non-EU countries.
A customs union is a free trade area with common external tariffs and uniform methods of handling imports. There are also no, or only minimal, checks and other bureaucracies at borders between members. The EU customs union means that individual EU countries are not permitted to do separate trade deals with non-EU countries.
Once the UK has left the EU, probably in around two years’ time, it will then be able to have different trade arrangements from the EU with countries outside the EU. Leaving the customs union would mean that the UK would face the EU’s common external tariff or around 5% on most goods, and 10% on cars.
Leaving the EU single market and customs union has been dubbed ‘hard Brexit’. Most businesses and many politicians had hoped that elements of the single market could be retained, such as tariff-free trade between the UK and the EU and free movement of capital. However, by leaving the single market, access to it will depend on the outcome of negotiations.
Negotiations will take place once Article 50 – the formal notice of leaving – has been invoked. The government has said that it will do this by the end of March this year. Then, under EU legislation, there will be up to two years of negotiations, at which point the UK will leave the EU.
The articles look at the nature of the EU single market and customs union and at the implications for the UK of leaving them.

A paper by three University of Sussex academics has just been published by the university’s UK Trade Policy Observatory (UKTPO). It looks at possible trade relations between the UK and the EU post Brexit. It identifies four key government objectives or constraints – what the authors call ‘red lines’ – and five possible types of trade arrangement with the EU.
The four red lines the authors identify are:
|
• |
Limitations on the movement of people/labour; |
• |
An independent trade policy; |
• |
No compulsory budgetary contribution to the EU; |
• |
Legal oversight by UK courts only and not by the European Court of Justice. |
Just how tight each of these four constraints should be is a matter for debate and political decision. For example, how extensive the limitations on the movement of labour should be and whether or not there should be any ‘voluntary’ budgetary contributions to the EU are issues where there is scope for negotiation.
Alongside these constraints is the objective of continuing to have as much access to and influence over the Single Market as possible.
The five possible types of trade arrangement with the EU identified in the paper are as follows:
|
1. |
Full Customs Union (CU) with the EU-27 |
2. |
Partial Customs Union with EU (based on EU-Turkey CU) |
3. |
Free Trade Area (FTA) with access to the Single Market (European Economic Area) |
4. |
Free Trade Area without automatic access to Single Market |
5. |
Reversion to World Trade Organisation (WTO) Most Favoured Nation (MFN) terms |
To clarify the terminology: a free trade area (FTA) is simply an agreement whereby member countries have no tariff barriers between themselves but individually can choose the tariffs they impose on imports from non-member countries; a customs union is a free trade area where all members impose common tariffs on imports from non-member countries and individual members are thus prevented from negotiating separate trade deals with non-member countries;
membership of the European Economic Area requires accepting freedom of movement of labour and compulsory contributions to the EU budget; WTO Most Favoured Nation rules would involve the UK trading with the EU but with tariffs equal to the most favourable ones granted to other countries outside the EU and EEA.
The red lines would rule out the UK being part of the customs union or the EEA. Although WTO membership would not breach any of the red lines, the imposition of tariffs against UK exports would be damaging. So the option that seems most appealing to many ‘Brexiteers’ is to have a free trade area agreement with the EU and negotiate separate trade deals with other countries.
But even if a tariff-free arrangement were negotiated with the EU, there would still be constraints imposed on UK companies exporting to the EU: goods exported to the EU would have to meet various standards. But this would constrain the UK’s ability to negotiate trade deals with other countries, which might demand separate standards.
The paper and The Economist article explore these constraints and policy alternatives and come to the conclusion that there is no easy solution. The option that looks the best “from the UK government’s point of view and given its red lines, would be an FTA with a variety of special sectoral arrangements”.

President-elect Donald Trump has blamed free trade for much of America’s economic problems. He argues that cheap imports from China, partly from an undervalued yuan, have led to a loss of jobs and to large-scale income flows from the USA to China. “They have taken our jobs; they have taken our money; and on top of that they have loaned the money to us and we actually pay them interest now on money,” he claimed to The Economist.
And it’s not just trade with China that he criticises. He sees cheap imports from developing countries generally as undermining US jobs. The solution he advocates is the imposition of tariffs on imports that threaten US jobs and scrapping, or fundamentally renegotiating, trade deals.
He refers to NAFTA – the North American Free Trade Agreement with Canada and Mexico – as the worst trade deal in US history and blames it for the loss of thousands of US manufacturing jobs. He has said that he will demand better terms from Mexico and Canada. If they don’t agree to them, he’d pull the USA out of NAFTA altogether.
A more recent trade agreement is the Trans-Pacific Partnership (TPP) with 11 other Pacific rim countries (but not including China). The agreement was signed on 4 February 2016, but is awaiting ratification from member countries. Amongst other things, the agreement cuts over 18,000 tariffs. Donald Trump has said that he would block the deal, even though it would lead to the elimination of tariffs on most US manufactured and agricultural products exported to the other countries. He argues that it would lead to a large-scale loss of US jobs from cheap imports.
Another major trade deal criticised by Trump is that being negotiated between the USA and the EU – the Transatlantic Trade and Investment Partnership (TTIP). It has already faced fierce opposition in Europe, with many fearing that it would give too much power to US corporations in their operations in Europe. With the opposition from Trump, it looks unlikely that the agreement will be signed, even in an amended form.
So is this more protectionist stance by Donald Trump in America’s interests? The main argument against restricting imports is that people generally in the USA would be poorer. This is the prediction from the law of comparative advantage. Trade allows a country to consume beyond its production possibility curve by specialising in the production of goods with relatively low opportunity costs and importing goods which would have had a higher opportunity cost if they were produced domestically (see, for example, Economics, 9th edition, pages 711–4). By imposing tariffs or other restrictions on cheap imports, consumers would end up paying more for such goods if they now have to be produced domestically. Cheap Chinese t-shirts would be replaced by expensive US ones. Real US incomes would be lower.
Another danger of pursuing protectionist policies is that other countries might retaliate. Trade wars might result, with the world ending up poorer.
Then there is a problem of locating products. It is not a simple question of saying a product is made in the USA or elsewhere. With complex modern supply chains, many products use components and services, such as design and logistics, from many different countries. Imposing restrictions on imports may lead to damage to products which are seen as US products.
An open trade policy, by contrast, not only leads to higher consumption, it stimulates economic growth and the extra competition it creates improves domestic productivity. As the pro-free trade article by Graeme Leach, linked below, argues:
There is overwhelming evidence that free trade improves economic performance by increasing competition in the domestic market. Trade disciplines domestic firms with market power, and simultaneously promotes productivity growth. Research also shows that a 10 per cent increase in trade leads to a 5 per cent increase in per capita income. More open trade policies are associated with higher per capita incomes.
And as the article by Clark Packard argues:
There is no question that America’s middle and lower classes have benefited from our trade liberalization. Through the widely accepted principle of comparative advantage in our trade policies, productivity has surged and prices have declined. Lower prices save the average American family thousands of dollars a year on goods they consume, raising the standard of living through enhanced purchasing power.
Despite these arguments, there is one crucial problem with free trade. Although overall levels of consumption may be higher, trade may make some people poorer. If workers in the US steel or garment industries lose their jobs because of cheap imports, they will certainly feel worse off, especially if there is no prospect of them getting another job elsewhere. They may lack transferable skills or have too many family or personal ties to move elsewhere in the country.
The government could help to ameliorate the problems of those made unemployed by providing retraining or resettlement grants or by investing in infrastructure projects that require relatively low skilled, but local, construction workers. But, as the Forbes article states:
It is in helping displaced workers of all types that US government, as well as the leaders of other rich countries, have largely failed. Little has been done to assist laid-off workers whose industries simply cannot compete in developed countries anymore.
What is more, inequality has been growing in the USA, and in most other developed countries too.
International trade and investment and the growing concentration of power in large corporations has meant that most of the gains from trade have gone to the richest people. Many of the poor blame trade for their plight and the argument that they have still made some gains is either not believed or is not enough to appease them.
An interesting insight into why people may have voted for Trump and his policy of protectionism is provided by the Ultimatum Game (see also). As the final article below explains:
The game itself involves two players. The first player receives a sum of money, and gets to propose how to divide it between the two players. The second player can do only one thing: accept or reject the proposal. If the second player accepts, then the money is divided between the two players as proposed. But if the second player rejects the proposal, then neither player gets anything.
It might seem that the rational thing for the second person to do is to accept whatever the first person proposes, however little it gives to the second person providing it is something – after all, even a little is better than nothing. But experiments show that people playing the second person do not behave in that way. They seek a fair distribution. If the proposed distribution is perceived as unfair, they would prefer to reject the proposal, with both players getting nothing.
This may help to explain the psychology of poor blue-collar workers. They would rather punish the rich a lot, and possibly themselves a little, than let the rich continue getting richer while they are stuck on low wages with little prospect for improvement. But, of course, they may also believe Trump’s rhetoric that they will indeed be better off from protectionist policies that help save their jobs.

What precisely Donald Trump will do about trade agreements and protection, we will have to wait and see. Often what is pledged in an election campaign is not carried out in office or is substantially watered down.
