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.

Questions
- What is a currency union? What implications would there be for Scotland being in a currency union with the rest of the UK?
- If you could measure the effects of independence over the next ten years, would you treat £1m of benefits or costs occurring in ten years’ time the same as £1m of benefits and costs occurring next year? Explain.
- Is it inevitable that events occurring in the future will at best be known unknowns?
- If you make a statement that something will occur in the future and you turn out to be wrong, was your statement a positive one or a normative one?
- What would be the likely effects of Scottish independence on the current account of the balance of payments (a) for Scotland; (b) for the rest if the UK?
- How does inequality in Scotland compare with that in the rest of the UK and in other countries? Why might Scottish independence lead to a reduction in inequality? (See the chapter on inequality in the book above edited by David Bell, David Eiser and Klaus B Beckmann.)
- One of the problems in assessing the arguments for a Yes vote is uncertainty over what would happen if there was a majority voting No. What might happen in terms of further devolution in the case of a No vote?
- Why is there uncertainty over the amount of national debt that would exist in Scotland if it became independent?
In 2009, interest rates in the UK were cut to a record low of 0.5%. Since that point, there has been almost unanimous agreement amongst the members of the Monetary Policy Committee to keep rates at this low. It is only in the last couple of months when some have even voted to raise rates. However, this month, interest rates were once again held at 0.5%.
The low interest rates have played a key part in creating an economic stimulus for the UK economy. With low interest rates, some of the key components of aggregate demand are stimulated and this in turn is crucial in creating a growth environment. However, with the recovery of the UK economy, there are now expectations that interest rates may soon begin to rise. Perhaps adding to this expectation is the fact that the bank’s stimulus programme has remained unchanged at £375bn. As more data is released that continues to show the positive progress of the UK economy, it becomes increasingly likely that interest rates will soon rise.
Despite the fact that interest rates will inevitably increase, Mark Carney has said that any increase will be slow and gradual to minimise the effect on consumers, especially home-owners. Mortgage payments are typically the biggest expenditure for a household and so any increase in interest rates will certainly put added pressure on home-owners and with wage growth still remaining slow, there are concerns of the impact this may have. Perhaps this may continue to deter some of the Committee for voting in favour of interest rate rises. There does appear to be some conflict between economists as to what the next step is likely to be. Yael Selfin is the economics director at KPMG and said:
With inflationary pressures still subdued, it is no surprise that rates have been held … Despite recent revisions to GDP and productivity, there is still room for further improvements in productivity, to mop up some of the rise in demand over the coming months. Steady falls in unemployment and strong economic growth are likely to see rates rising in February next year.
However, Andrew Goodwin, who is the senior economic adviser to the EY ITEM Club commented that:
On one hand, the stronger performance might convince some members that the economy is sufficiently robust to withstand the steady tightening of policy, although it should be noted that the Bank routinely builds into its forecasts the expectation of some upward revisions to the recent historical data … On the flip side, the revisions also provide some ammunition for those of a dovish persuasion, with evidence that a stronger productivity performance has had little feed through into inflationary pressures.
The key question therefore appears to be not whether interest rates will increase, but when. The MPC certainly considers inflation when making its decisions, but over the past few years, it is economic growth which has probably been the biggest influence. The data for the UK economy over the coming months, as well as the fast-approaching General Election, will prove crucial in determining exactly when interest rates increase. The following articles consider this monetary policy change.

Questions
- By outlining the key components of aggregate demand, explain the mechanisms by which interest rates will affect each component.
- How can inflation rates be affected by interest rates?
- Why is there a debate between economists and the MPC as to when interest rates should be increased?
- If interest rates do increase, how is this likely to affect home-owners?
- What are the advantages and disadvantages of a slow and gradual rise as opposed to one big rise?
The eurozone recorded 0.0% growth in the second quarter of 2014. While the UK and USA are now experiencing relatively buoyant economic growth, the eurozone as a whole is stagnating. Some of the 18 eurozone countries, it is true, are now growing, including Spain, Portugal, Ireland and the Netherlands. But the German and Italian economies contracted in the three months to the end of June, while France experienced zero growth.
This will put growing pressure on the ECB to introduce quantitative easing (QE) through the direct purchase of government bonds or other assets. Although this has been a key policy of many central banks, including the Bank of England, the Fed and the Bank of Japan, up to now the ECB has focused mainly on providing cheap funds to banks to encourage them to lend and keeping interest rates very low.

In June, the ECB did announce that it would explore the possibility of QE. It would also introduce €400 billion worth of targeted long-term lending to banks (targeted longer-term refinancing operations (TLTROs)), and would cease sterilising the extra liquidity injected through the Securities Markets Programme, which involved the purchase of existing bonds on the secondary market.
These plans and their implications are examined in the blog post, The ECB: tackling the threat of deflation.
But even if it does eventually introduce QE, this is unlikely before 2015. However, the first €200 billion of TLTROs will be introduced in September and the remaining €200 billion in December. The ECB hopes that these measures in the pipeline will give a sufficient stimulus to rekindle economic growth. But increasingly there are calls for something more dramatic to be done to prevent the eurozone as a whole slipping back into recession.

The most commonly used measure of economic performance is GDP and while there is agreement that it is an important and useful measure, there is also agreement that there are some big problems with it. Does it measure welfare or quality of life? What is and isn’t included? Do some things add to GDP which actually make us worse off?
One criticism often levelled at GDP is that there are many aspects that go unmeasured – often known as the underground economy. Some areas are typical everyday things – DIY, looking after your own children rather than paying someone to do it, or even giving yourself a haircut. But, there are other activities, often illegal, which go unrecorded, such as the selling and distribution of drugs and prostitution. In countries like the Netherlands, their GDP figures get a boost, as some drugs and prostitution are legal. In other countries, such data is not recorded and as such, the contribution of these markets is under-estimated or even completely omitted.
However, this aspect of the calculation of GDP statistics is changing across Europe, which will allow much easier and more meaningful comparisons of relative GDP across countries. This extra production will therefore offer a positive contribution towards our GDP and perhaps suggest to the untrained eye that the British economy is growing, which can only be good news. But, for the trained economist, we are looking at extra data being added, which will boost total output and the question will be does it really indicate that the economy is better off? The following articles consider this change to GDP.

The expansion of the BRIC economies has both advantages and disadvantages for Western countries. Their consistently high growth rates have created a much wider market place for Western firms and a much needed additional source of consumer demand, especially in times of recession. Countries such as China have had double digit growth rates, with others like India experiencing growth rates of just under 10%. But are these impressive growth rates now beginning to fall?
For the last 2 years, the growth rate in the Indian economy has been sub-5%, with growth in the 2013-14 financial year at 4.7%. Though some sectors, including agriculture have experienced buoyant growth, it is other sectors that have been holding this economy back. Manufacturing contracted at an annualised rate of 1.4% over the quarter, while mining contracted by 0.4%. With a growth rate of just under 5%, one might think that this was good – after all many Western economies have only recently entered positive growth. However, the Indian economy has a rapidly growing population and it is estimated that 10 million additional jobs each year must be created. It is this figure that requires such a high growth rate – estimated at around 8%. Thus, the sub-5% growth recorded for 2 years is insufficient to sustain the required job creation.

There are many factors that appear to be holding growth back. High inflation has been a problem for some years and the Indian currency has been relatively weak and volatile. Together, these issues have created an environment of uncertainty and if there’s one thing that investors don’t like, it’s uncertainty. This has therefore led to a lack of investment in the economy, which is a key component of aggregate demand and hence a key source of economic growth. Furthermore, interest rates rose last year, thereby pushing up the cost of borrowing and the rate of credit growth has also slowed. These factors collectively have led to lower foreign investment, domestic investment and spending, which have all contributed towards more subdued growth than in the past. Glenn Levine, a senior economist at Moody’s said:
India’s economy continues to grow well below potential as a combination of supply‐side constraints and the adverse effects of an underperforming government weigh on capital expenditure and hiring … It will be a while before the Indian economy is expanding above 6% again.
However, many economists remain optimistic about the prospects of Asia’s third-largest economy. Inflation appears to be under control and the currency has gained strength. Many believe that more investment supporting government policies will be the kick start the economy needs and this will in turn encourage firms to begin investment. It may be the new leader of this country, Narendra Modo, that will jump start the economy. The Prime Minister is expected to back policies to stimulate growth, who will direct more spending at infrastructure, simplify taxes and introduce policies to attract foreign investment. Adi Godrej, Chairman of the Godrej group said:
As soon as investors see the first signals of growth-supportive policies, you will see a definite turnaround on the ground.
The coming months will be crucial in determining how quickly the Indian economy is likely to see a return to near double digit growth. The new government has indeed promised policies to boost the economy, but the annual budget will confirm whether this promise is likely to be kept. Given the dependence of Indian jobs on a fast growth rate and the dependence of the Western world on the continued growth of the BRICs in creating a wider market for our exports, the fortunes of India are extremely important.
