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.

At the end of January 2014, we looked at the problem of deflation and in particular at the fortunes of Japan, as its CPI was rising. As the blog explained, the Japanese economy, rather than being plagued by high inflation has been plagued by deflation and many suggest this is even worse.
In December 2013, Japan’s core consumer prices were growing faster than expected. The data gave the economy a much needed boost, following increases in government spending aimed at stimulating aggregate demand. This in turn pushed up prices, such that they achieved their fastest rate of growth in 5 years. Now, more recent date from May 2014 shows that the trend has continued. Prices in Japan have now increase at their fastest rate in 23 years, rising 3.2% and beating the forecasts of 3.1%. This means that prices have no risen in Japan for 11 consecutive months. Numerous policies have contributed towards this impressive trend for an economy plagued by deflation for 2 decades. Boosts in the money supply, increases in government spending, a rise in sales tax are just some of the contributing factors.
Although the economy is certainly over the problem of deflation, some are now concerned that such price rises may reduce consumer spending. An ironic twist, given that barely a year ago the concern about low consumer spending was due to deflation. The next 12 months will be a key indicator of how consumers will respond to this unusual inflation data – after all inflation and high prices have been pretty uncommon. The following articles consider the update on the Japanese economy.

Questions
- Why is deflation a problem?
- Using an AD/AS diagram, illustrate the problem of expectations and how this contributes to stagnant growth.
- Japanese policies have helped create a rise in the CPI. Which policies have been effective in creating rising prices?
- Explain how the sales tax has contributed towards higher prices.
- With prices rising, there are now concerned that consumer spending may decline. Using a diagram, explain why this may be the case.
- In the previous blog, we analysed the Indian economy and said that high inflation was something that was contributing towards lower growth. How is that low inflation or deflation can also contribute towards low growth?
Rising inflation: not normally a cause for celebration, but that’s not the case for Japan. Having been subject to the spectre of deflation for many years, the 22-year high for the CPI at 2.7% is a welcome figure, even it is slightly lower than expected. This surge in prices is partly the result of a growth in domestic demand and a sign, therefore, that output will expand in response to the rise in demand.
The Japanese economy has experienced largely stagnant growth for two decades and a key cause has been falling prices. Although consumers like bargains, this has been problematic for this large economy. Deflation creates continuously falling prices and this means consumers hold back from purchasing durable goods, preferring to wait until prices have fallen further.

In the blog, Japan’s recovery, we looked at inflation data showing Japanese consumer prices growing at a faster rate than expected. This ‘positive’ trend has continued.
When it comes to inflation, expectations are crucial. If people think prices will rise in the future, they are more likely to buy now to get the lower price. This can therefore help to stimulate aggregate demand and it is this that has been the target for Japan. Part of the growth in the CPI is down to the sales tax rise from 5% to 8%. This was the first time in 17 years that the sales tax had increased. Further increases in it are expected in 2015. There were concerns about the impact of this rise, based on the depression that followed the last rise back in 1997, but so far the signs seem good.
Monetary easing was a key component in ending the downward trajectory of the Japanese economy and, following the sales tax rise, many believe that another round of monetary easing may be needed to counter the effects and create further growth in the economy and in the CPI. As the Bank of Japan Governor said:
There are various ways to adjust policy. We will decide what among these measures is appropriate depending on economic and price developments at the time … For now, we can say Japan is making steady progress toward achieving 2 per cent inflation.
One of the ‘three arrows‘ of the government’s policy has been to boost government spending, which should directly increase aggregate demand. Furthermore, with signs of the CPI rising, consumers may be encouraged to spend more, giving a much needed boost to consumption. The economy is certainly not out of the woods, but appears to be on the right path. The following articles consider the Japanese economy.

Unemployment and employment are concepts that are often talked about in the media. Indeed, the 7% unemployment target referred to by the Governor of the Bank of England has been a constant feature of recent headlines. However, rather than targeting an unemployment rate of 7%, George Osborne has now called for ‘full employment’ and believes that tax and welfare changes are key to meeting this objective.
Reducing the unemployment rate is a key macroeconomic objective and the costs of unemployment are well-documented. There are obviously big costs to the individual and his/her family, including lower income, dependency, stress and potential health effects. There are also costs to the government: lower income tax revenues, potentially lower revenues from VAT through reduced consumer expenditure and the possibility of higher benefit payments. There are other more ‘economic’ costs, namely an inefficient use of resources. Unemployment represents a cost to the economy, as we are operating below full capacity and we therefore see a waste of resources. It is for this reason that ‘full employment’ is being targeted.
Traditional economic theory suggests that there is a trade-off between unemployment and inflation, illustrated by the well-known Phillips curve. In the past, governments have been willing to sacrifice unemployment for the purpose of reducing inflation. There have also been attempts to boost the economy and create jobs through increased borrowing. However, George Osborne has said:
Unemployment is never a price worth paying, but artificial jobs paid for with borrowed money doesn’t work either.
A figure representing full employment hasn’t been mentioned, so it remains unclear what level of unemployment would be acceptable, as despite the name ‘full employment’, this doesn’t mean that everyone has a job. There are several definitions of full employment, in both an economic and political context. In the period of reconstruction after the Second World War, William Beveridge, architect of the welfare state, defined full employment as where 3% of people would be unemployed.
In more recent times, other definitions have been given. In the era of monetarism in the 1970s, the term ‘natural rate of unemployment’ was used to define the unemployment rate to which economies tend in the long run – after inflationary expectations have adjusted. Keynesians use the term the ‘non-accelerating-inflation rate of unemployment (NAIRU)’, where unemployment is confined to equilibrium unemployment and where there is no excess or deficiency of aggregate demand. Both the natural rate and the NAIRU relate to the rate of unemployment at which the long-run Phillips curve is vertical.

In its Economic and Fiscal Outlook of March 2013, the Office for Budget Responsibility estimated the UK’s NAIRU to be 5.4%. George Osborne has not specified a particular rate. Rather, his speech refers to creating the ‘highest employment rate of any of the world’s leading economies’. He said the ambition was to make the UK:
…the best place in the world to create a job; to get a job; to keep a job; to be helped to look for another job if you lose one…A modern approach to full employment means backing business. It means cutting the tax on jobs and reforming welfare.
Therefore, while it appears that there is no target figure for unemployment, it seems that a new Conservative objective will be to focus on sustainable job creation and eliminate disequilibrium unemployment. This represents a move very much into Labour territory. Meeting the objective will be no easy task, given the past few years and such high levels of youth unemployment, as Labour were quick to point out, but the unemployment figures are certainly moving in the right direction. The following articles consider the objective of full employment.

The growth of China over the past decade has been quite phenomenal, with figures recorded in double-digits. However, in the aftermath of the recession, growth has declined to around 7% – much higher than Western economies are used to, but significantly below the ‘norm’ for China. (Click here for a PowerPoint of the chart.)
The growth target for this year is 7.5%, but there appear to be some concerns about China’s ability to reach this figure and this has been emphasised by a recent Chinese policy.
A mini-stimulus package has been put in place, with the objective of meeting the 7.5% growth target. Government expenditure is a key component of aggregate demand and when other components of AD are lower than expected, boosting ‘G’ can be a solution. However, it’s not something that the Chinese government has had to do in recent years and the fact that this stimulus package has been put in place has brought doubts over China’s economic performance to the forefront , but has confirmed its commitment to growth. Mizuho economist, Shen Jianguang, said:
It’s very obvious that the leaders feel the need to stabilise growth…Overall, the 7.5 per cent growth target means that the government still cares a lot about economic growth.
Data suggest that growth in China is relatively weak and there are concerns that the growth target will be missed, hence the stimulus package. In the aftermath of the 2008 financial crisis, there was a large stimulus package in place in China. This latest investment by the government is in no way comparable to the size of the 2008 package, but instead will be on a smaller and more specific scale. Mark Williams of Capital Economics said:
It’s a bit of a rerun of what we saw last year – something less than a stimulus package and more of piecemeal measures to ensure they reach their growth target.
It is the construction of public housing and railways that will be the main areas of investment this time round. A sum of $120–180bn per year will be available for railway construction and $161bn for social housing, and tax breaks are being extended for small businesses.
The 2008 stimulus package saw debt increase to some 200% of GDP, which did cause growing concerns about the reliance on debt. However, this latest package will be financed through the issue of bonds, which is much more similar to how market economies finance spending.
The fact that the government has had to intervene with such a stimulus package is, however, causing growing concerns about the level of debt and the future of this fast growing economy, though the new method of financing is certainly seen as progress.
It should be noted that a decline in growth for China is not only concerning for China itself, but is also likely to have adverse consequences other countries. In the increasingly interdependent world that we live in, Western countries rely on foreign consumers purchasing their exports, and in recent years it has been Chinese consumers that have been a key component of demand. However, a decline in growth may also create some benefits – resources may not be used up as quickly and prices of raw materials and oil in particular may remain lower.
It is certainly too early for alarm bells, but the future of China’s growth is less certain than it was a decade ago. The following articles consider this issue.
