Although the Monetary Policy Committee (MPC) of the Bank of England is independent in setting interest rates, until recently it still had to follow a precise remit set by the government. This was to target inflation of 2% (±1%), with interest rates set to meet this target in 24 months’ time. But things have changed since the new Governor, Mark Carney, took up office in July 2013. And now things are not so clear cut.
The Bank announced that it would keep Bank Rate at the current historically low level of 0.5% at least until unemployment had fallen to 7%, subject to various conditions. More generally, the Bank stated that:
The MPC intends at a minimum to maintain the present highly stimulative stance of monetary policy until economic slack has been substantially reduced, provided this does not entail material risks to price stability or financial stability.
This ‘forward guidance’ was designed to provide more information about future policy and thereby more certainty for businesses and households to plan.
But unemployment has fallen rapidly in recent months. It fell from a 7.7% average for the three months May to July 2013 to 7.1% for the latest available three months (September to November 2013). 
And yet there is still considerable slack in the economy.
It now, therefore, looks highly unlikely that the MPC will raise Bank Rate as soon as unemployment falls below 7%. This then raises the question of how useful the 7% target has been and whether, if anything, it has created further uncertainty about future MPC decisions.
The following still appears on the Bank of England website:
The MPC intends at a minimum to maintain the present highly stimulative stance of monetary policy until economic slack has been substantially reduced, provided this does not entail material risks to price stability or financial stability.
But this raises two questions: (a) how do you measure ‘economic slack’ and (b) what constitutes a substantial reduction?
So what should the Bank do now? What, if any, forward guidance should it offer to the markets? Will that forward guidance be credible? After all, credibility among businesses and households is an important condition for any policy stance. According to Larry Elliott in the first article below, there are five options.

Microsoft’s Office suite is the market leader in the multi-billion dollar office software market. Although an oligopoly, thanks to strong network economies Microsoft has a virtual monopoly in many parts of the market. Network economies occur when it saves money and/or time for people to use the same product (software, in this case), especially within an organisation, such as a company or a government.
Despite the rise of open-source software, such as Apache’s OpenOffice and Google Docs, Microsoft’s Office products, such as Word, Excel and PowerPoint, still dominate the market. But are things about to change?
The UK government has announced that it will seek to abandon reliance on Microsoft Office in the public sector. Provided there are common standards within and across departments, it will encourage departments to use a range of software products, using free or low-cost alternatives to Microsoft products where possible. This should save hundreds of millions of pounds.
Will other governments around the world and other organisations follow suit? There is a lot of money to be saved on software costs. But will switching to alternatives impose costs of its own and will these outweigh the costs saved?

The UK Shadow Chancellor, Ed Balls, has announced that, if Labour is returned to power in the next election, it will bring back the 50% top rate of income tax (see also). This will apply to incomes over £150,000.
But will this raise more tax revenue? The question here concerns incentive effects. Will the higher rate of income tax discourage work by those earning £150,000 or encourage tax avoidance or tax evasion, so that the total tax take is reduced? The Conservatives say the answer is yes. The Labour party says no, claiming that there will still be an increase in tax revenue.
The possible effects are summed up in the Laffer curve (see The 50p income tax rate and the Laffer curve). As the previous post stated:
These arguments were put forward in the 1980s by Art Laffer, an adviser to President Reagan. His famous ‘Laffer curve’ (see Economics (8th edition) Box 10.3) illustrated that tax revenues are maximised at a particular tax rate. The idea behind the Laffer curve is very simple. At a tax rate of 0%, tax revenue will be zero – but so too at a rate of 100%, since no-one would work if they had to pay all their income in taxes. As the tax rate rises from 0%, so tax revenue would rise. And so too, as the tax rate falls from 100%, the tax rate would rise. It follows that there will be some tax rate between 0% and 100% that maximises tax revenue.
As Labour is claiming that re-introducing the 50% top rate of income tax will increase tax revenue, the implication is that the economy is to the left of the top of the Laffer curve: that, at current level of income, the curve is still rising.
Work by HMRC, and published in the document The Exchequer effect of the 50 per cent additional rate of income tax, suggested that the previous cut in the top rate from 50% to 45% would cut revenue by around £3.5 billion if there were no incentive effect, but with the extra work that would be generated, the cut would be a mere £100 million. This implies, other things being equal, that a rise in the rate from 45% to 50% would raise only a tiny bit of extra taxes.
However, the HMRC analysis has been criticised and especially its assumptions about the incentive effects on work. Then there is the question of whether a rise in the rate from 45% to 50% would have exactly the reverse effect of a cut from 50% to 45%. And then there is the question of how much HMRC could reduce tax evasion and avoidance.
The following article from the Institute for Fiscal Studies examines the effects. However, the authors conclude that:
… at the moment, the best evidence we have still suggests that raising the top rate of tax would raise little revenue and make, at best, a marginal contribution to reducing the budget deficit an incoming government would face after the next election.
But there is also the question of equity. Putting aside the question of how much revenue would be raised, is it fair to raise the top rate of tax for those on high incomes? Would it make an important contribution to reducing inequality? This normative question lies at the heart of the different views of the world between left and right and is not a question that can be answered by economic analysis.

50p tax – strolling across the summit of the Laffer curve? Institute for Fiscal Studies, Paul Johnson and David Phillips (Jan 2014)
Questions
- Distinguish between tax evasion and tax avoidance.
- How would it be possible for a rise in tax rates to generated less tax revenue?
- Could policies shift the Laffer curve as opposed to merely resulting in a move along the curve?
- What is meant by ‘taxable income elasticity (TIE)’? What are its determinants?
- Is the taxable income elasticity at the top of the Laffer curve equal to, above or below zero? Explain.
- Why did the Office for Budget Responsibility chairman, Robert Chote, conclude that, whatever the precise answer, we were ‘strolling across the summit of the Laffer curve’?
- Explain why ‘there is little additional evidence to suggest that a 50p rate would raise more than was estimated by HMRC back in 2012’.
- What contribution can economists make to the debate on the desirability of reducing inequality?
In a speech in Edinburgh, Mark Carney, Governor of the Bank of England, considered the implications of Scotland retaining the pound if the Scottish people vote yes for independence. His speech was intended to be non-political. Rather he focused on two main questions: first whether a currency union of Scotland and the rest of the UK (RUK) would be an optimal currency area; second how much economic sovereignty would need to be shared with RUK as a consequence of Scotland keeping the pound.
On the first question, Mark Carney argued that the current UK is close to an optimal currency area as there is a high degree of economic integration and factor mobility. Sharing a currency eliminates exchange costs, improves pricing transparency and hence encourages competition, promotes cross-border investment, improves the flow of technology and ideas, and increases the mobility of labour and capital.
But sharing a currency involves sharing a monetary policy. This would still be determined by the Bank of England and would have to geared to the overall economic situation of the union, not the specific needs of Scotland.
There would also need to be a banking union, whereby banks in difficulties would receive support from the whole currency area. In Scotland’s case, banking accounts for a very large proportion of the 
economy (12.5% compared with 4.3% for RUK) and could potentially place disproportionate demands on the currency union’s finances.
And then there is the question of fiscal policy. A shared currency also means pooling a considerable amount of sovereignty over taxation, government spending and government debt. This could be a serious problem in the event of asymmetric shocks to Scotland and RUK. For example, if oil prices fell substantially, Scotland may want to pursue a more expansionary fiscal policy just at a time when its tax revenues were falling. This could put a strain on Scotland’s finances. This might then require RUK to provide support from a common pool of funds, such as a ‘regional fund’.
Being in a currency union can amplify fiscal stress, and increase both the risks and consequences of financial instability. In the situation just described [a fall in demand for exports], fiscal policy would ideally help smooth adjustment to the external shock. But its ability to do so could be limited by the budgetary impact of the falls in output, prices and wages. To maintain credibility, fiscal policy may even become pro-cyclical, with the resulting austerity exacerbating the initial fall in demand. In the extreme, adverse fiscal dynamics could call into question a country’s membership of the union, creating the possibility of self-fulfilling ‘runs’ on bank and sovereign debt absent central bank support.6 Such adverse feedback loops turned recessions into depressions in several European countries in recent years.
A separate Scottish currency, by contrast, would, according to Carney, be a valuable shock absorber if domestic wages and prices were sticky.
For example, suppose demand for a country’s exports falls. All else equal, its output will fall, unemployment increase and current account deteriorate. With an independent currency, exchange rate depreciation can dampen these effects by improving competitiveness, and monetary policy can become more accommodative, supporting demand and employment. However, if the country were part of a currency area with its foreign market, its exchange rate would by definition not change, putting the full weight of adjustment on wages and unemployment – a significantly more protracted and painful process. In addition, the responsiveness of monetary policy to weak demand in that country would be diluted by the needs of the broader membership.
But despite the problems of ceding a degree of monetary and fiscal sovereignty, Scotland and RUK are well placed to continue with a successful currency union if Scotland becomes independent. Economic conditions are very similar, as are language, culture and institutions, and there is an effective banking union – assuming such a banking union were to continue post independence.
The existing banking union between Scotland and the rest of the United Kingdom has proved durable and efficient. Its foundations include a single prudential supervisor maintaining consistent standards of resilience, a single deposit guarantee scheme backed by the central government, and a common central bank, able to act as Lender of Last Resort across the union, and also backed by the central government. These arrangements help ensure that Scotland can sustain a banking system whose collective balance sheet is substantially larger than its GDP.
The desirability of Scottish independence is a normative question for the Scottish electorate to decide. Nevertheless, economists have an important part to play in informing the debate. Mark Carney’s economic analysis of currency union if the Scottish electorate votes yes is a good example of this.

World markets were taken by surprise by a large rise in Turkish interest rates on 28/1/14. In an attempt to combat a falling lira and rising inflation, the Turkish central bank raised its overnight lending rate from 7.75% to 12%. Following the decision, the lira appreciated by over 3%.
Since the start of this year, the Turkish lira had depreciated by 7.1% and since the start of 2013 by 22.8%. Along with the currencies of several other emerging economies, such as India and Brazil, speculators had been selling the Turkish currency. This has been triggered by worries that the Fed’s tapering off its quantitative easing programme would lead to a fall, and perhaps reversal, of the inflow of finance into these countries; in the worst-case scenario it could lead to substantial capital flight.
Consumer price inflation in Turkey is currently 7.4%, up from 6.2% a year ago. The central bank, in a statement issued alongside the interest rate rise, said that it would continue with a tight monetary
policy until the inflation outlook showed a clear improvement.
The Turkish Prime Minister, Tayyip Erdogan, has been opposed to rises in interest rates, fearing that the dampening effect on aggregate demand would reduce economic growth, which, as the chart shows, has been recovering recently (click here for a PowerPoint of the chart). A slowing of growth could damage his prospects in forthcoming elections.
World stock markets, however, rallied on the news, seeing the rise in interest rates as a symbolic step in emerging countries stemming outflows of capital.

Although the Monetary Policy Committee (MPC) of the Bank of England is independent in setting interest rates, until recently it still had to follow a precise remit set by the government. This was to target inflation of 2% (±1%), with interest rates set to meet this target in 24 months’ time. But things have changed since the new Governor, Mark Carney, took up office in July 2013. And now things are not so clear cut.
