A general election has been called in the UK for 12 December. Central to the debates between the parties will be their policy on Brexit.
They range from the Liberal Democrats’, Plaid Cymru’s and Sinn Féin’s policy of cancelling Brexit and remaining in the EU, to the Scottish Nationalists’ and Greens’ policy of halting Brexit while a People’s Vote (another referendum) is held, with the parties campaigning to stay in the EU, to the Conservative Party’s policy of supporting the Withdrawal Agreement and Political Declaration negotiated between the Boris Johnson government and the EU, to the DUP which supports Brexit but not a version which creates a border between Great Britain and Northern Ireland, to the Brexit Party and UKIP which support leaving the EU with no deal (what they call a ‘clean break’) and then negotiating individual trade deals on a country-by-country basis.
The Labour Party also supports a People’s Vote, but only after renegotiating the Withdrawal Agreement and Political Declaration, so that if Brexit took place, the UK would have a close relationship with the single market and remain in a customs union. Also, various laws and regulations on environmental protection and workers’ rights would be retained. The referendum would take place within six months of the election and would be a choice between this new deal and remain.
But what are the economic costs and benefits of these various alternatives? Prior to the June 2016 referendum, the Treasury costed various scenarios. After 15 years, a deal would make UK GDP between 3.4% and 7.8% lower than if it remained in the EU, depending on the nature of the deal. No deal would make GDP between 5.4% and 9.5% lower.
Then in November 2018, the Treasury published analysis of the original deal negotiated by Theresa May in July 2018 (the ‘Chequers deal’). It estimated that GDP would be up to 3.9% lower after 15 years than it would have been if the UK had remained in the EU. In the case of a no-deal Brexit, GDP would be up to 9.3% lower after 15 years.
When asked for Treasury forecasts of the effects of Boris Johnson’s deal, the Chancellor, Sajid Javid, said that the Treasury had not been asked to provide forecasts as the deal was “self-evidently in our economic interest“.
Other forecasters, however, have analysed the effects of the Johnson deal. The National Institute for Economic and Social Research (NIESR), the UK’s longest established independent economic research institute, has estimated the costs of various scenarios, including the Johnson deal, the May deal, a no-deal scenario and also a scenario of continuing uncertainty with no agreement over Brexit. The NIESR estimates that, under the Johnson deal, with a successful free-trade agreement with the EU, in 10 years’ time UK GDP will be 3.5% lower than it would be by remaining in the EU. This represents a cost of £70 billion. The costs would arise from less trade with the EU, lower inward investment, slower growth in productivity and labour shortages from lower migration. These would be offset somewhat by savings on budget contributions to the EU.
Under Theresa May’s deal UK GDP would be 3.0% lower (and thus slightly less costly than Boris Johnson’s deal). Continuing in the current situation with chronic uncertainty about whether the UK would leave or remain would leave the UK 2% worse off after 10 years. In other words, uncertainty would be less damaging than leaving. The costs from the various scenarios would be in addition to the costs that have already occurred – the NIESR estimates that GDP is already 2.5% smaller than it would have been as a result of the 2016 Brexit vote.
Another report also costs the various scenarios. In ‘The economic impact of Boris Johnson’s Brexit proposals’, Professors Anand Menon and Jonathan Portes and a team at The UK in a Changing Europe estimate the effects of a decline in trade, migration and productivity from the various scenarios – again, 10 years after new trading arrangements are in place. According to their analysis, UK GDP would be 4.9%, 6.4% and 8.1% lower with the May deal, the Johnson deal and no deal respectively than it would have been from remaining in the EU.
But how much reliance should we put on such forecasts? How realistic are their assumptions? What other factors could they have taken into account? Look at the two reports and at the articles discussing them and then consider the questions below which are concerned with the nature of economic forecasting.

The Institute of Fiscal Studies (IFS) has just published its annual ‘Green Budget‘. This is, in effect, a pre-Budget report (or a substitute for a government ‘Green Paper’) and is published ahead of the government’s actual Budget.
The Green Budget examines the state of the UK economy, likely economic developments and the implications for macroeconomic policy. This latest Green Budget is written in the context of Brexit and the growing likelihood of a hard Brexit (i.e. a no-deal Brexit). It argues that the outlook for the public finances has deteriorated substantially and that the economy is facing recession if the UK leaves the EU without a deal.
It predicts that:
Government borrowing is set to be over £50 billion next year (2.3% of national income), more than double what the OBR forecast in March. This results mainly from a combination of spending increases, a (welcome) change in the accounting treatment of student loans, a correction to corporation tax revenues and a weakening economy. Borrowing of this level would breach the 2% of national income ceiling imposed by the government’s own fiscal mandate, with which the Chancellor has said he is complying.
A no-deal Brexit would worsen this scenario. The IFS predicts that annual government borrowing would approach £100 billion or 4% of GDP. National debt (public-sector debt) would rise to around 90% of GDP, the highest for over 50 years. This would leave very little scope for the use of fiscal policy to combat the likely recession.
The Chancellor, Sajid Javid, pledged to increase public spending by £13.4bn for 2020/21 in September’s Spending Review. This was to meet the Prime Minister’s pledges on increased spending on police and schools. This should go some way to offset the dampening effect on aggregate demand of a no-deal Brexit. The government has also stated that it wishes to cut various taxes, such as increasing the threshold at which people start paying the 40% rate of income tax from £50 000 to £80 000. But even with a ‘substantial’ fiscal boost, the IFS expects little or no growth for the two years following Brexit.
But can fiscal policy be used over the longer term to offset the downward shock of Brexit, and especially a no-deal Brexit? The problem is that, if the government wishes to prevent government borrowing from soaring, it would then have to start reining in public spending again. Another period of austerity would be likely.
There are many uncertainties in the IFS predictions. The nature of Brexit is the obvious one: deal, no deal, a referendum and a remain outcome – these are all possibilities. But other major uncertainties include business and consumer sentiment. They also include the state of the global economy, which may see a decline in growth if trade wars increase or if monetary easing is ineffective (see the blog: Is looser monetary policy enough to stave off global recession?).
- Why would a hard Brexit reduce UK economic growth?
- To what extent can expansionary fiscal policy stave off the effects of a hard Brexit?
- Does it matter if national debt (public-sector debt) rises to 90% or even 100% of GDP? Explain.
- Find out the levels of national debt as a percentage of GDP of the G7 countries. How has Japan managed to sustain such a high national debt as a percentage of GDP?
- How can an expansionary monetary policy make it easier to finance the public-sector debt?
- How has investment in the UK been affected by the Brexit vote in 2016? Explain.
There have been many analyses of the economic effects of Brexit, both before the referendum and at various times since, including analyses of the effects of the deal negotiated by Theresa May’s government and the EU. But with the prospect of a no-deal Brexit on 31 October under the new Boris Johnson government, attention has turned to the effects of leaving the EU without a deal.
There have been two major analyses recently of the likely effects of a no-deal Brexit – one by the International Monetary Fund (IMF) and one by the Office for Budget Responsibility (OBR).
The first was in April by the IMF as part of its 6-monthly World Economic Outlook. In Scenario Box 1.1. ‘A No-Deal Brexit’ on page 28 of Chapter 1, the IMF looked at two possible scenarios.
Scenario A assumes no border disruptions and a relatively small increase in UK sovereign and corporate spreads. Scenario B incorporates significant border disruptions that increase import costs for UK firms and households (and to a lesser extent for the European Union) and a more severe tightening in financial conditions.
Under both scenarios, UK exports to the EU and UK imports from the EU revert to WTO rules. As a result, tariffs are imposed by mid-2020 or earlier. Non-tariff barriers rise at first but are gradually reduced over time. Most free-trade arrangements between the EU and other countries are initially unavailable to the UK (see the blog EU strikes major trade deals) but both scenarios assume that ‘new trade agreements are secured after two years, and on terms similar to those currently in place.’
Both scenarios also assume a reduction in net immigration from the EU of 25 000 per year until 2030. Both assume a rise in corporate and government bond rates, reflecting greater uncertainty, with the effect being greater in Scenario B. Both assume a relaxing of monetary and fiscal policy in response to downward pressures on the economy.
The IMF analysis shows a negative impact on UK GDP, with the economy falling into recession in late 2019 and in 2020. This is the result of higher trade costs and reduced business investment caused by a poorer economic outlook and increased uncertainty. By 2021, even under Scenario A, GDP is approximately 3.5% lower than it would have been if the UK had left the EU with the negotiated deal. For the rest of the EU, GDP is around 0.5% lower, although the effect varies considerably from country to country.
The IMF analysis makes optimistic assumptions, such as the UK being able to negotiate new trade deals with non-EU countries to replace those lost by leaving. More pessimistic assumptions would lead to greater costs.
Building on the analysis of the IMF, the Office for Budget Responsibility considered the effect of a no-deal Brexit on the public finances in its biennial Fiscal risks report, published on 17 July 2019. This argues that, under the relatively benign Scenario A assumptions of the IMF, the lower GDP would result in annual public-sector net borrowing (PSNB) rising. By 2021/22, if the UK had left with the deal negotiated with the EU, PSNB would have been around £18bn. A no-deal Brexit would push this up to around £51bn.
According to the OBR, the contributors to this rise in public-sector net borrowing of around £33bn are:
- A fall in income tax and national insurance receipts of around £16.5bn per year because of lower incomes.
- A fall in corporation tax and expenditure taxes, such as VAT, excise duties and stamp duty of around £22.5bn per year because of lower expenditure.
- A fall in capital taxes, such as inheritance tax and capital gains tax of around £10bn per year because of a fall in asset prices.
- These are offset to a small degree by a rise in customs duties (around £10bn) because of the imposition of tariffs and by lower debt repayments (of around £6bn) because of the Bank of England having to reduce interest rates.
The rise in PSNB would constrain the government’s ability to use fiscal policy to boost the economy and to engage in the large-scale capital projects advocated by Boris Johnson while making the substantial tax cuts he is proposing. A less optimistic set of assumptions would, of course, lead to a bigger rise in PSNB, which would further constrain fiscal policy.

- What are the assumptions of the analysis of a no-deal Brexit on the public finances in the OBR’s Fiscal risks report? Do you agree with these assumptions? Explain.
- What is the difference between forecasts and analyses of outcomes?

Donald Trump has threatened to pull out of the World Trade Organization. ‘If they don’t shape up, I would withdraw from the WTO,’ he said. He argues that the USA is being treated very badly by the WTO and that the organisation needs to ‘change its ways’.
Historically, the USA has done relatively well compared with other countries in trade disputes brought to the WTO. However, President Trump does not like being bound by an international organisation which prohibits the unilateral imposition of tariffs that are not in direct retaliation against a trade violation by other countries. Such tariffs have been imposed by the Trump administration on steel and aluminium imports. This has led to retaliatory tariffs on US imports by the EU, China and Canada – something that is permitted under WTO rules.
Whether or not the USA does withdraw from the WTO, Trump’s threats bring into question the power of the WTO and other countries’ compliance with WTO rules. With the rise in protectionist sentiments around the world, the power of the WTO would seem to be on the wane.
Even if the USA does not withdraw from the WTO, it is succeeding in weakening the organisation. Appeals cases have to be heard by an ‘appellate body’, consisting of at least three judges drawn from a list of seven, each elected for four years. But the USA has the power to block new appointees – and has done so. As Larry Elliott states in the first article below:
The list of judges is already down to four and will be down to the minimum of three when the Mauritian member, Shree Baboo Chekitan Servansing, retires at the end of September. Two more members will go by the end of next year, at which point the appeals process will come to a halt.
This raises the question of the implication of a ‘no-deal’ Brexit – something that seems more likely as the UK struggles to reach a trade agreement with the EU. Leaving without a deal would mean ‘reverting to WTO rules’. But if these rules are being ignored by powerful countries such as the USA and possibly China, and if the appeals procedure has ground to a halt, this could leave the UK without the safety net of international trade rules. Outside the EU – the world’s most powerful trade bloc – the UK could find itself having to accept poor trade terms with the USA and other large countries.
- Explain the WTO’s ‘Most-favoured-nation (MFN)’ clause. How would this affect trade deals between the UK and the EU?
- Would the trade deals that the EU has negotiated with other countries, such as Japan, be available to the UK after leaving the EU?
- Demonstrate how, according to the law of comparative advantage, all countries can gain from trade.
- In what ways is the USA likely to gain and lose from the imposition of tariffs on steel and aluminium?
- How could a country that supports free trade ever support the imposition of tariffs?
- Why are tariffs not the most serious restriction on trade?
