In the blog post, Global warning, we looked at the use of unconventional macroeconomic policies to deal with the slow pace of economic growth around the world. One of the articles was by Nouriel Roubini. In the linked article below, he argues that slow economic growth may be the new global norm.
At the centre of the problem is a fall in the rate of potential economic growth. This has been caused by a lack of investment, which has slowed the pace of innovation and the growth in labour productivity.
The lack of investment, in turn, has been caused by a lack of spending by both households and governments. What is the point in investing in new capacity, argue firms, if they already have spare capacity?
Low consumer spending is partly the result of a redistribution of income from low- and middle-income households (who have a high marginal propensity to consume) to high-income households and corporations (who have a low mpc). Low spending is also the result of both consumers and governments attempting to reduce their levels of debt by cutting back spending.
Low growth leads to hysteresis – the process whereby low actual growth leads to low potential growth. The reason is that the unemployed become deskilled and the lack of investment by firms reduces the innovation that is necessary to embed new technologies.
Read Roubini’s analysis and consider the policy implications.

Has the global economic growth malaise become the ‘new normal’? The Guardian, Nouriel Roubini (2/5/16)
Questions
- Explain what is meant by ‘hysteresis’ and how the concept is relevant in explaining low global economic growth.

- Explain what Roubini means by ‘a painful de-leveraging process’. What are the implications of this process?
- How important are structural reforms and what forms could these take? Why has there been a reluctance for governments to institute such reforms?
- ‘Asymmetric adjustment between debtor and creditor economies has also undermined growth.’ Explain what Roubini means by this.
- Why are governments reluctant to use fiscal policy to boost both actual and potential economic growth?
- What feasible policy measures could be taken to boost actual and potential economic growth?
According to the BBC’s Joe Lynam, “Britain has the most competitive and dynamic retail environment in the world, which attracts shoppers globally.” It is perhaps this fact which may save BHS, with new owners being attracted by such an opportunity. BHS is soon expected to file for administration, with debts of more than £1.3 billion and having failed to secure the loan needed to keep it afloat. If this company collapses, it will bring an end to the life of an 88 year old giant.
The British retail scene has certainly changed over the past decade, with names such as Woolworths and Comet disappearing – could BHS be the next casualty of the changing retail climate? In the world of retail, tastes change quickly and those stores who fail to change with the times are the ones that suffer. One of the factors behind the downfall of BHS is the ‘dated’ nature of its stores and fashions. As clothing outlets such as Zara, Oasis and Next have continued to change with the times, commentators suggest that BHS continues with a trading offer from the 1980s. With the online shopping trend, many household names adapted their strategy, but BHS failed to do so and the second chance that BHS asked the public for when Sir Philip Green, its former owner, sold BHS in 2015 hasn’t materialised.
With administrators ready to be brought in and thousands of jobs hanging in the balance, the administrators will be looking at methods to attract funding, new owners or so-called ‘cherry pickers’ who may be interested in buying up the more profitable stores. Some of their stores remain in prime locations and deliver a tidy profit and it is perhaps these gems, together with the tradition that British Home Stores brings that may yet see the company saved. The outcome for BHS will not only affect the jobs of its employees, but will affect the pensions of thousands of workers. The BHS pension fund currently has a deficit of £576 million and so the Pension Protection Fund will have to look closely at the situation before thinking about issues a contribution notice to those connected with the fund.
A deal was on the cards last week, with BHS owner Dominic Chappell in talks with Mike Ashley’s Sports Direct, but the high debts and pensions deficit appears to have deterred this deal. The failing fortunes of BHS have now come back to haunt former owner, Sir Philip Green, who in March 2015, sold the business for just £1. Sir Philip may return to save the day, but the options for this once giant of the British high street are rather limited. The following articles consider the fortunes of BHS.

- What type of market structure does BHS operate in? Can this be used to explain why it is in its current position?
- How has the company failed in adapting its business strategy to the changing times?
- Looking back at the history of BHS, can you apply the product life cycle to this store?
- If another company is considering purchasing BHS, or at least some of its stores, what key information will it need and what might make it likely to go ahead with such a purchase?
The Treasury has published a paper analysing the costs of Britain leaving the EU. Its central assumption is that the UK would negotiate a bilateral trade deal with the EU similar to that between Canada and the EU. Under this assumption the Treasury estimates that, by 2030, GDP would be 6.2% lower than if the UK had remained in the EU, meaning that the average household would be £4300 per year worse off than it would otherwise have been. The analysis also finds that there would be a total reduction in tax receipts of £36 billion per year – far greater than any savings from lower contributions to the EU budget.
Not surprisingly the ‘Vote Remain’ campaign for the UK to stay in the EU has welcomed the analysis, seeing it as strong evidence in support of their case. Also, not surprisingly, the Vote Leave campaign has questioned both the analysis and the assumptions on which it is based.
The Treasury analysis looks at three possible scenarios: (a) a Canada-style bilateral arrangement (the central estimate); (b) the UK becoming a member or the European Economic Area – the ‘Norwegian model’ (according to the Treasury, this would reduce GDP by 3.8%); (c) no specific deal with the EU, with the UK simply having the same access to the EU as any other country that is a mamber of the WTO (this would reduce GDP by 7.5%). Thus the Norwegian model would probably result in a smaller reduction in growth, but the UK would still continue to make contributions to the EU budget and have to allow free movement of labour. Only in option (c) would it have total control over migration. Each of the estimates has a margin of error, giving a range for the reduction in GDP across the three scenarios from 3.4% to 9.5%.
The Treasury used a three-stage process to arrive at its conclusions, as explained in the FT article below:
First, it uses gravity models to estimate the effect of different trade relationships on the quantity of trade and foreign direct investment. Gravity models take into account how close countries are to each other geographically, as well as their historical links, rather than assuming that trade flows to wherever the lowest tariffs are.
Second, it uses external academic results to estimate the consequences for productivity – the efficiency of the UK economy – from different levels of trade and foreign direct investment.
Third, it plugs the productivity numbers unto a global economic model run by the National Institute of Economic and Social Research to estimate the long-run differences in national income and prosperity.
Clearly there is large-scale uncertainty over any forecasts 14 years ahead, especially when the relationship with the EU and other countries post-EU exit can only be roughly estimated. The question is whether the assumptions are reasonable and whether there would be substantial costs from Brexit, but not necessarily of £4300 per household.
The following articles look at the analysis and its assumptions. Unlike many newspaper articles, which clearly have an agenda, these articles are relatively unbiased and try to assess the arguments. Of course, it would be difficult to be totally unbiased and it would be a good idea to try to spot any biases in each of the articles.

In a recent post, Global Warning, we looked at concerns about the global economy. One of these was about the ineffectiveness of monetary policy to stimulate aggregate demand and to restore growth rates. Despite the use of unconventional monetary policies, such as quantitative easing and negative interest rates, and despite the fact that these policies have become the new convention, they have failed to do enough to bring sustained recovery.
The two articles below argue that the failure has been due to a flawed model of monetary policy: one that takes too little account of the behaviour of banks and the drivers of consumption and of physical investment. Negative interest rates on banks’ holdings of reserves in central banks are hardly likely to push down lending rates to businesses sufficiently to stimulate investment in new plant and machinery if firms already have overcapacity. And consumers are unlikely to borrow more for consumption if their wages are barely rising and they already have debts that they fear will be difficulty to pay off.
As Joseph Stiglitz points out:
As real interest rates have fallen, business investment has stagnated. According to the OECD, the percentage of GDP invested in a category that is mostly plant and equipment has fallen in both Europe and the US in recent years. (In the US, it fell from 8.4% in 2000 to 6.8% in 2014; in the EU, it fell from 7.5% to 5.7% over the same period.) Other data provide a similar picture.
And the unwillingness of many firms and individuals to borrow is matched by banks’ caution about lending in an uncertain economic environment. Many are more concerned about building their capital and liquidity ratios to protect themselves.
In these circumstances, negative interest rates have little effect on stimulating bank lending and, by hurting their balance sheets through lower earnings on the money markets, may even encourage them to lend less
What central banks should be doing, argue both Stiglitz and Elliott, is finding ways of directly stimulating consumption and investment. Perhaps this will involve central banks “focusing on the flow of credit, which means restoring and maintaining local banks’ ability and willingness to lend to SMEs.” Perhaps it will mean using helicopter money, as we examined in the previous blog. As Larry Elliott points out:
The fact that economists at Deutsche Bank published a helpful cut-out-and-keep guide to helicopter
money last week is a straw in the wind.
As the Deutsche research makes clear, the most basic variant of helicopter money involves a central bank creating money so that it can be handed to the finance ministry to spend on tax cuts or higher public spending. There are two differences with QE. The cash goes directly to firms and individuals rather than being channelled through banks, and there is no intention of the central bank ever getting it back.
So if the model of monetary policy is indeed flawed, prepare for more unconventional measures

Questions
- What arguments does Stiglitz use to support his claim that the model of monetary policy currently being used is flawed?
- In what ways has monetary policy hurt older people and what has been the effect on their spending and on aggregate demand in general?
- Why has monetary policy encouraged investors to shift their portfolios toward riskier assets?
- Examine the argument that ultra-low interest rates may result in a rise in unemployment in the long term by affecting the relative prices of capital and labour.
- What forms might helicopter money take?
- Would the use of helicopter money necessarily result in an increase in aggregate demand? What would determine the size of any such increase?
In a recent blog Accelerating interest in the interesting case of UK interest rates we compared the level of the official Bank Rate, which has now been at 0.5 per cent for over seven years, with a representative unsecured borrowing rate. In doing so, we found some evidence that credit conditions might be easing following the credit market disturbance of the late 2000s. Here we take the opportunity not only to review that data again one month on, but also to see whether a similar picture is true for the mortgage market.
Theories of the financial accelerator argue that the macroeconomic environment can affect commercial banks’ lending practices. One way in which this can operate is through the difference between banks’ lending rates and the official Bank Rate. We can think of such interest-rate differentials – or spreads – as a credit premium. The size of the premium may be thought to reflect lenders’ perceived risk of default by borrowers. It is argued by some economists that interest-rate differentials will fall when the economy is doing well and increase when the economy is doing less well. This is because the probability of default by borrowers is seen as smaller when the macroeconomic environment improves.
The effect of interest-rate differentials that are contingent on the macroeconomic environment is to amplify the business cycle. For example, a positive demand-side shock, such as a rise in consumer confidence, which causes the economy’s aggregate demand to rise will, in turn, lead to lower borrowing rates relative to the official Bank Rate. This financial effect further stimulates the demand for credit and, as a consequence, aggregate demand and economic activity. It is an example of what economists called the financial accelerator.
The chart shows the Bank Rate along with the average unsecured borrowing rate on loans by Monetary Financial Institutions (MFIs) of £10 000. Unlike secured borrowing, which we consider shortly, unsecured borrowing is not secured against property.
As expected, we can see that the unsecured borrowing rate is greater than the Bank Rate. In other words, there is a positive interest-rate differential. However, this differential is seen to vary. It falls sharply in the period up to the financial crisis. In early 2002 it was running at 8 percentage points. By summer 2007 the differential had fallen to only 1.7 percentage points. (Click here to download a PowerPoint of the chart.)
The period from 2002 to 2007 was characterised by consistently robust growth with the UK economy growing by about 2.7 per cent per annum over this period. This may point to economic growth can contributing to an easing of credit conditions as implied by the financial accelerator.
The story from 2008 changes very quickly as the interest-rate differential increases very sharply. In 2009, as the official Bank Rate was cut to 0.5 per cent, the unsecured borrowing rate climbed to close to 10.5 per cent. Consequently, the interest-rate differential rose to 10 percentage points. Inter-bank lending had dried up with banks concerned that banks would default on loans. The increase in interest rates on lending to the non-bank private sector was stark and evidence of a credit market disruption.
The interest-rate differential for unsecured borrowing has steadily declined since its peak at the end of 2009 as the unsecured borrowing rate has fallen. This implies that credit conditions have eased. In March 2016 our interest-rate differential for unsecured borrowing stood at 3.8 percentage points, not dissimilar to levels over the past 12 months. Interestingly, today’s differential on unsecured borrowing is lower than the 6.5 percentage point average over the period from 1997 to 2003, before the differential then went on its pre-crisis fall.
Our second chart repeats the analysis but this time for mortgages. The representative mortgage rate is the average standard variable mortgage rate.
Unlike that for unsecured borrowing, the interest-rate differential for mortgages is fairly constant up to the financial crisis. The widely report credit easing in the mortgage market appears to have operated more through amounts lent rather than through price, as evidenced by rising mortgage advance-to-income ratios. (Click here to download a PowerPoint of the chart.)
The second chart shows clear evidence of a credit market disruption from 2009. Hence, the markets for secured and unsecured lending saw credit conditions tighten with interest-rate differentials rising markedly. However, it shows that the higher interest-rate differential for secured lending following the credit market disruption remains. So while the differential has fallen sharply for unsecured lending the situation is quite different in the mortgage market. In fact, February and March 2016 saw the mortgage rate spread at 4.17 percentage points which is an historic high.

Our interest rate data show that interest-rate differentials can vary significantly over time. This is important to understand when we are thinking about the relationships between the macroeconomy and the financial system. Significantly, the data suggest that interest rates on different financial instruments can behave differently such that differences emerge in the patterns of spreads over the official Bank Rate.
The evidence on UK mortgage rates suggests that the market remains affected by the financial crisis and the credit market disruption that arose. Although the level of mortgage rates is historically low – which tends to capture many of the headlines – this masks an historically high premium over the official Bank Rate.
