Economic journalists, commentators and politicians have been examining the possible economic effects of a Yes vote in the Scottish independence referendum on 18 September. For an economist, there are two main categories of difficulty in examining the consequences. The first is the positive question of what precisely will be the consequences. The second is 
the normative question of whether the likely effects will be desirable or undesirable and how much so.
The first question is largely one of ‘known unknowns’. This rather strange term was used in 2002 by Donald Rumsfeld, US Secretary of Defense, in the context of intelligence about Iraq. The problem is a general one about forecasting the future. We may know the types of thing that are likely happen, but the magnitude of the outcome cannot be precisely known because there are so many unknowable things that can influence it.
Here are some known issues of Scottish independence, but with unknown consequences (at least in precisely quantifiable terms). The list is certainly not exhaustive and you could probably add more questions yourself to the list.
|
|
| • |
Will independence result in lower or higher economic growth in the short and long term? |
| • |
Will there be a currency union, with Scotland and the rest of the UK sharing the pound and a central bank? Or will Scotland merely use the pound outside a currency union? Would it prefer to have its own currency or join the euro over the longer term? |
| • |
What will happen to the sterling exchange rate with the dollar, the euro and various other countries? |
| • |
How will businesses react? Will independence encourage greater inward investment in Scotland or will there be a net capital outflow? And either way, what will be the magnitude of the effect? |
| • |
How will assets, such as oil, be shared between Scotland and the rest of the UK? And how will national debt be apportioned? |
| • |
How big will the transition costs be of moving to an independent Scotland? |
| • |
How will independence impact on Scottish trade (a) with countries outside the UK and (b) with the rest of the UK? |
| • |
What will happen about Scotland’s membership of the EU? Will other EU countries, such as Spain (because of its concerns about independence movements in Catalonia and the Basque country), attempt to block Scotland remaining in or rejoining the EU? |
| • |
What will happen to tax rates in Scotland, with the new Scottish government free to set its own tax rates? |
| • |
What will be the consequences for Scottish pensions and the Scottish pensions industry? |
| • |
What will happen to the distribution of income in Scotland? How might Scottish governments behave in terms of income redistribution and what will be its consequences on output and growth? |
Of course, just because the effects cannot be known with certainty, attempts are constantly being made to quantify the outcomes in the light of the best information available at the time. These are refined as circumstances change and newer data become available.
But forecasts also depend on the assumptions made about the post-referendum decisions of politicians in Scotland, the rest of the UK and in major trading partner countries. It also depends on assumptions about the reactions of businesses. Not surprisingly, both sides of the debate make assumptions favourable to their own case.
Then there is the second category of question. Even if you could quantify the effects, just how desirable would they be? The issue here is one of the weightings given to the various costs and benefits. How would you weight distributional consequences, given that some people will gain or lose more than others? What social discount rate would you apply to future costs and benefits?
Then there are the normative and largely unquantifiable costs and benefits. How would you assess the desirability of political consequences, such as greater independence in decision-making or the break-up of a union dating back over 300 years? But these questions about nationhood are crucial issues for many of the voters.

World leaders are meeting at the World Economic Forum in Davos, in the Swiss Alps. This annual conference is an opportunity for politicans, economists and businesspeople from around the world to discuss the state of the world economy and to consider policy options.
To coincide with the conference, the BBC’s Newsnight has produced the following slide show, which presents some economic facts about the world economy. The slide show provides no commentary and there is no commentary either in this blog – just some questions for you to ponder.
Using the economics you’ve learned so far, try answering these questions, which focus on the reasons for the patterns in the figures, the likely future patterns and the policy implications.

- Go through each of the slides in the Newsnight presentation and select the ones of most interest to you. Then, as an economist, provide an explanation for them.
- Identify some patterns over time in the statistics. Then project forward 20 years and discuss whether the patterns are likely to have changed and, if so, why.
- What policies could governments adopt to reverse any undesirable trends you have identified? How likely are these policies to be implemented and how successful are they likely to be?
The Conservatives have pledged that, if they win the next election, they will hold a referendum in 2017 on whether or not the UK should remain in the EU. The Prime Minister has also said that he will renegotiate the terms of UK membership and push for reforms to the EU to cut administrative costs, reduce intervention and make the EU more competitive. We are likely to be bombarded with arguments for and against membership over the coming months.
In a contribution to the debate, the CBI has just published research showing that membership of the EU benefits the UK by up to £78 billion per year – £3000 per household. It also conducted a poll of its members which shows that the vast majority (78%, including 77% of SMEs) want to remain part of the EU, believing that membership brings net benefits to their business and the economy more generally.
However, as the Director-General of the CBI, John Cridland, said:
But the EU isn’t perfect and there is a growing unease about the creeping extension of EU authority. Europe has to become more open, competitive and outward looking if we are to grow and create opportunities and jobs for all our citizens.
The following articles and documents look at the CBI’s arguments.

A key debate for some months has been the UK’s membership of the European Union. The debate has centred around the desire to return some powers back to the UK, but this has extended into the possibility of a referendum on our membership of the preferential trading area. So, let’s take a step back and consider why any country would want to be a member of a preferential trading area.
Preferential trading areas can be as basic as a free trading area or as advanced as a currency, or even political union. The eurozone is clearly a currency union, but the European Union, of which the UK is a member, is a common market. A common market has no tariffs and quotas between the members, but in addition there are common external tariffs and quotas. The European union also includes the free movement of labour, capital and goods and services. Membership of a preferential trading area therefore creates benefits for the member countries. One such benefit is that of trade creation. Members are able to trade under favourable terms with other members, which yields significant benefits. Countries can specialise in the production of goods/services in which they have a comparative advantage and this enables greater quantities of output to be produced and then traded.
Other benefits include the greater competition created. By engaging in trade, companies are no longer competing just with domestic firms, but with foreign firms as well. This helps to improve efficiency, cut costs and thus lower prices benefiting consumers. However, from a firm’s point of view there are also benefits: they have access to a much wider market in which they can sell their goods without facing tariffs. This creates the potential for economies of scale to be achieved. Were the UK to completely exit the EU, this could be a significant loss for domestic firms and for consumers, who would no longer see the benefits of no tariffs on imported goods. Membership of a preferential trading area also creates benefits in terms of potential technology spillovers and is likely to have a key effect on a country’s bargaining power with the rest of the world. As is a similar argument to membership of a trade union, there is power in numbers.
There are costs of membership of a preferential trading area, but they are typically outweighed by the benefits. However, estimates suggest that the cost of EU regulation is the equivalent of 10% of UK GDP. Furthermore, while the UK certainly does trade with Europe, data suggests that only 13% of our GDP is dependent on such exports. The future is uncertain for the European Union and Britain’s membership. There are numerous options available besides simply leaving this preferential trading area, but they typically have one thing in common. They will create uncertainty and this is something that markets and investors don’t like. Vince Cable warned of this, saying:
There are large numbers of potential investors in the UK, who would bring employment here, who have been warned off because of the uncertainty this is creating.
The impact of the UK’s decision will be significant and not just for those living and working in the economy. The world is no interdependent that when countries exist (or typically enter) a preferential trading area the wider economic effects are significant. While any change in the UK’s relationship with the EU will take many months and years to occur and then further time to have an effect, the uncertainty created by the suggestion of a change in the relationship has already sent waves across the world. The following articles consider the wider single market and the current debate on UK membership.

- In each of the above examples, explain the type of preferential trading area that it is.
- What are the benefits and costs of being a member of a preferential trading area such as the EU? How do these differ to being a member of a) a free trade area and (b) a customs union?
- What options are open to the UK in terms of re-negotiating its relationship with the EU? In each case, explain how the benefits and costs identified in question 3 would change.
- Why is the UK’s decision so important for the global economy? Would it be in the interests of other economies? Explain your answer.
International economists have long advocated the advantages of free trade. By boosting competition, increasing choice and market size, trade has long been seen as an engine of growth and efficiency.
For many years, tariffs and other restrictive trade practices have been removed on trade between both developed and developing countries and many rounds of negotiations have taken place, with mixed results.
The World Trade Organisation (WTO) plays a key role in trade negotiations and has the main aim of liberalising trade. The organisation requires its members to operate according to a variety of rules, including the prohibition of quotas and the inability of countries to raise existing tariffs without negotiating with their trading partners.
If any country breaks a trade agreement, the WTO can impose sanctions. A current case that has been referred to the WTO for ‘consultation’ concerns Argentina. Argentina has imposed various import restrictions on trade, such as import licensing and a requirement for countries to balance its exports and imports.
A number of WTO members recently expressed their concerns about these restrictive trade practices. The EU trade commissioner Karel de Gucht said:
Argentina’s import restrictions violate international trade rules and must be removed. These measures are causing very real damage to EU companies – hurting jobs and our economy as a whole. … Argentina’s trade policy has become rooted in unfair trade practices.
Argentina has said that it was expecting the move from the EU, but claims that its protectionist measures are there to support and re-industrialise the country. This case is unlikely to be resolved any time soon and while the ‘restrictive trade practices’ remain in place, EU companies trying to export to Argentina will find barriers, such as a requirement for all imports to receive pre-approval.
The effects of these restrictions have already been felt, with EU exports to Argentina down by 4% in April this year, compared with the same month last year. The following articles consider this issue.
