One of the key questions about Brexit is its effect on UK trade and cross-border investment. Once outside the customs union, will the freedom to negotiate trade deals lead to an increase in UK exports and GDP, as many who support Brexit claim; or will the increased frictions in trade with the EU, and the need to negotiate new trade deals with those non-EU countries which already have trade deals with the EU, lead to a fall in exports and in GDP?
Also, how will trade restrictions or new trade deals affect capital flows? Will there be an increase in inward investment or a flight of investment to the EU or elsewhere? Will many companies relocate away from the UK – or to it?
Although there has been a cost up to now from the Brexit vote, in terms of a depreciation in sterling and a fall in inward investment (see the first article below), the future effects have been hard to predict as the terms on which the UK will leave the EU have been unclear. However, with a draft withdrawal agreement between the EU and the UK government having been reached, the costs and benefits are becoming clearer. But there is still uncertainty about just what the effects on trade and investment will be.
- First, the 585-page draft withdrawal agreement is not a trade deal. It contains details of UK payments to the EU, commitments on the rights of EU and UK citizens and confirmation of the transition period – initially until 31 December 2020, but possibly extended with mutual agreement. During the transition agreement, the UK would remain a member of the customs union and single market and remain subject to rulings of the European Court of Justice. The withdrawal agreement also provides for a continuation of the customs union beyond the transition period, if no long-term trade agreement is in place. This is to prevent he need for a hard border between Ireland and Northern Ireland.
- Second, there is merely a 26-page ‘political declaration‘ about future trade relations. Negotiations on the details of these can only begin once the UK has left the EU, scheduled for 29 March 2019. So it’s still unclear about just how free trade in both goods and services will be between the UK and the EU and how freely capital and labour will move between them. But with the UK outside the single market, there will be some limitations on trade and factor movements – some frictions.
- Third, it is not clear whether the UK Parliament will agree to the withdrawal agreement. Currently, it seems as if a majority of MPs is in favour of rejecting it. If this happens, will the UK leave without an agreement, with trade based on WTO terms? Or will the EU be prepared to renegotiate it – something it currently says it will not do? Or will the issue be put back to the electorate in the form of a People’s vote (see also), which might contain the option of seeking to remain in the EU?
So, without knowing just what the UK’s future trade relations will be with (a) the EU, (b) non-EU countries which have negotiated trade deals with the EU, (c) other countries without trade deals with the EU, it is impossible to quantify the costs and benefits from the effects on trade and investment. However, the consensus among economists is still that there will be a net cost in terms of lost trade and inward investment.
Such as view is backed by a government analysis of various Brexit scenarios, released in time for the House of Commons vote on 11 December. This concludes that the UK will be worse off under all Brexit alternatives compared with staying in the EU. The main brake on growth will be frictions in trade from tariff and non-tariff barriers.
This analysis was supported by a Bank of England paper which modelled various scenarios based on assumptions about different types of Brexit deal. While recognising the inherent uncertainty in some of the empirical relationships, it still concluded that Brexit would be likely to have a net negative effect. The size of this negative effect would depend on the closeness of the new relationship between the UK and EU, the degree of preparedness across firms and critical infrastructure, and how other policies respond.
- Identify the main economic advantages and disadvantages for the UK from leaving the EU?
- How does the law of comparative advantage relate to the question of the relative trade gains from leaving and remaining in the EU?
- What is the difference between the following models of relationship with the EU: the Switzerland model; the Norway model; the Turkey model; the Canada (plus or plus, plus) model; trading on WTO terms?
- Why is the consensus among economists that there will be a net economic cost from leaving the EU, no matter on what terms?
- Is the UK likely to achieve more favourable trade deals with non-EU countries as an independent country or as a member of the EU benefiting from EU-negotiated trade deals with such countries?
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.

- 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?

- 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?
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:
||Full Customs Union (CU) with the EU-27
||Partial Customs Union with EU (based on EU-Turkey CU)
||Free Trade Area (FTA) with access to the Single Market (European Economic Area)
||Free Trade Area without automatic access to Single Market
||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”.
Brexit means…a lot of complex trade decisions The Economist, Buttonwood’s notebook (15/11/16)
UK–EU Trade Relations post Brexit: Too Many Red Lines? UK Trade Policy observatory (UKTPO), Briefing Paper No. 5, Michael Gasiorek, Peter Holmes and Jim Rollo (November 2016)
- Explain the difference between a free trade area, a customs union and a single market.

Many of the arguments used by both sides in the referendum debate centre on whether there will be a net economic gain from either remaining in or leaving the EU. This involves forecasting.
Forecasting the economic impact of the decision, however, is difficult, especially in the case of a leave vote, which would involve substantial change and uncertainty.
First, the effects of either remaining or leaving may be very different in the long run from the short run, and long-run forecasts are highly unreliable, as the economy is likely to be affected by so many unpredictable events – few people, for example, predicted the financial crisis of 2007–8.
Second, the effects of leaving depend on the nature of any future trading relationships with the EU. Various possibilities have been suggested, including ‘the Norwegian model’, where Britain leaves the EU, but joins the European Economic Area, giving access to the single market, but removing regulation in some key areas, such as fisheries and home affairs. Another possibility is ‘the Swiss model’, where the UK would negotiate trade deals on an individual basis. Another would be ‘the Turkish model’ where the UK forms a customs union with the EU. At the extreme, the UK could make a complete break from the EU and simply use its membership of the WTO to make trade agreements.
Nevertheless, despite the uncertainty, economists have ventured to predict the effects of remaining or leaving. These are not precise predictions for the reasons given above. Rather they are based on likely assumptions.
In a poll of 100 economists for the Financial Times, ‘almost three-quarters thought leaving the EU would damage the country’s medium-term outlook, nine times more than the 8 per cent who thought the country would benefit from leaving’. Most fear damage to financial markets in the UK and to inward foreign direct investment.
Despite the barrage of pessimistic forecasts by economists about a British exit, there is a group of eight economists in favour of Brexit. They claim that leaving the EU would lead to a stronger economy, with higher GDP, a faster growth in real wages, lower unemployment and a smaller gap between imports and exports. The main argument they use to support their claims is that the UK would be more able to pursue trade creation freed from various EU rules and regulations.
Then, less than four weeks before the vote, a poll of economists who are members of the Royal Economic Society and the Society of Business Economists came out strongly in favour of continued membership of the EU. Of the 639 respondents, 72 per cent thought that the most likely impact of Brexit on UK real GDP would be negative over the next 10 to 20 years; and 88 per cent thought the impact on GDP would be negative in the next five years (see chart: click to enlarge).
Of those stating that a negative impact on GDP in the next 5 years would be most likely, a majority cited loss of access to the single market (67%) and increased uncertainty leading to reduced investment (66%).
The views of the majority of economists accord with those of various organisations. Domestic ones, such as the Bank of England, the Treasury (see the blog Brexit costs), the Institute for Fiscal Studies and the National Institute for Economic and Social Research (NIESR) all warn that Brexit would be likely to result in lower growth – possibly a recession – increased unemployment, a fall in the exchange rate and higher prices and that greater economic uncertainty would damage investment.
International organisations, such as the OECD, the IMF and the WTO, also argue that leaving the EU would create great uncertainty over future trade relations and access to the Single Market and would reduce inward foreign direct investment and the flow of skills.
But the forecasts of all these organisations depend on their assumptions about trade relations and that, in the event of the UK leaving the EU, would depend on the outcome of trade negotiations. The Leave campaign argues that other countries would want to trade with the UK and that therefore leaving would not damage trade. The Remain campaign argues that the EU would not wish to be generous to the UK for fear of encouraging other countries to leave the EU and that, anyway, the process of decoupling from the EU and negotiating new trade deals would take many years and, in the meantime, the uncertainty would be damaging to investment and growth.
The articles linked below looks at the economic arguments about Brexit and reflect the range of views of economists. Several are from ‘The Conversation’ as these are by academic economists. Although some economists are in favour of Brexit, the vast majority support the Remain side in the debate.
