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.

One of President Trump’s main policy slogans has been ‘America first’. As Trump sees it, a manifestation of a country’s economic strength is its current account balance. He would love the USA to have a current account surplus. As it is, it has the largest current account deficit in the world (in absolute terms) of $481 billion in 2016 or 2.6% of GDP. This compares with the UK’s $115bn or 4.4% of GDP. Germany, by contrast, had a surplus in 2016 of $294bn or 8.5% of GDP.
However, he looks at other countries’ current account surpluses suspiciously – they may be a sign, he suspects, of ‘unfair play’. Germany’s surplus of over $50bn with the USA is particularly in his sights. Back in January, as President-elect, he threatened to put a 35% tariff on imports of German cars.
In practice, Germany is governed by eurozone rules, which prevent it from subsidising exports. And it does not have its own currency to manipulate. What is more, it is relatively open to imports from the USA. The EU imposes an average tariff of just 3% on US imports and importers also have to add VAT (19% in the case of Germany) to make them comparably priced with goods produced within the EU.
So why does Germany have such a large current account surplus? The article below explores the question and dismisses the claim that it’s the result of currency manipulation or discrimination against imports. The article states that the reason for the German surplus is that:
… it saves more than it invests. The correspondence of savings minus investment with exports minus imports is not an economic theory; it’s an accounting identity. Germans collectively spend less than they produce, and the difference necessarily shows up as net exports.
But why do the Germans save so much? The answer given is that, with an aging population, Germans are sensibly saving now to support themselves in old age. If Germany were to reduce its current account surplus, this would entail either the government reducing its budget surplus, or people reducing the amount they save, or some combination of the two. This is because a current account surplus, which consists of exports and other incomes from abroad (X) minus imports and any other income flowing abroad (M), must equal the surplus of saving (S) plus taxation (T) over investment (I) plus government expenditure (G). In terms of withdrawals and injections, given that:
I + G + X = S + T + M
then, rearranging the terms,
X – M = (S + T) – (I + G).
If German people are reluctant to reduce the amount they save, then an alternative is for the German government to reduce taxation or increase government expenditure. In the run-up to the forthcoming election on 24 September, Chancellor Merkel’s centre-right CDU party advocates cutting taxes, while the main opposition party, the SPD, advocates increasing government expenditure, especially on infrastructure. The article considers the arguments for these two approaches.

Economists were generally in favour of the UK remaining in the EU and highly critical of the policy proposals of Donald Trump. And yet the UK voted to leave the EU and Donald Trump was elected.
People rejected the advice of most economists. Many blamed the failure of most economists to predict the 2007/8 financial crisis and to find solutions to the growing gulf between rich and poor, with the majority stuck on low incomes.
So to what extent are economists to blame for the rise in populism – a wave that could lead to electoral upsets in various European countries? The podcast below brings together economists and politicians from across the political spectrum. It is over an hour long and provides an in-depth discussion of many of the issues and the extent to which economists can provide answers.

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.

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.
