Category: Essentials of Economics: Ch 08

Policymakers around the world have used Gross Domestic Product as the main gauge of economic performance – and have often adopted policies that aim to maximise its rate of growth. Generation after generation of economists have committed significant time and effort to thinking about the factors that influence GDP growth, on the premise that an expanding and healthy economy is one that sees its GDP increasing every year at a sufficient rate.

But is economic output a good enough indicator of national economic wellbeing? Costanza et al (2014) (see link below) argue that, despite its merits, GDP can be a ‘misleading measure of national success’:

GDP measures mainly market transactions. It ignores social costs, environmental impacts and income inequality. If a business used GDP-style accounting, it would aim to maximize gross revenue — even at the expense of profitability, efficiency, sustainability or flexibility. That is hardly smart or sustainable (think Enron). Yet since the end of the Second World War, promoting GDP growth has remained the primary national policy goal in almost every country. Meanwhile, researchers have become much better at measuring what actually does make life worthwhile. The environmental and social effects of GDP growth is a misleading measure of national success. Countries should act now to embrace new metrics.

The limitations of GDP growth as a measure of economic wellbeing and national strength are becoming increasingly clear in today’s world. Some of the world’s wealthiest countries are plagued by discontent, with a growth in populism and social discontent – attitudes which are often fuelled by high rates of poverty and economic hardship. In a recent report titled ‘The Living Standards Audit 2018’ published by the Resolution Foundation, a UK economic thinktank (see link below), the authors found that child poverty rose in 2016–17 as a result of declining incomes of the poorest third of UK households:

While the economic profile of UK households has changed, living standards – with the exception of pensioner households – have mostly stagnated since the mid-2000s. Typical household incomes are not much higher than they were in 2003–04. This stagnation in living standards for many has brought with it a rise in poverty rates for low to middle income families. Over a third of low to middle income families with children are in poverty, up from a quarter in the mid-2000s, and nearly two-fifths say that they can’t afford a holiday away for their children once a year. On the other hand, the share of non-working families in poverty has fallen, though not by enough to prevent an overall rise in poverty since 2010.

Their projections also show that this rise in poverty was likely to have continued in 2017–18:

Although the increase in broad measures of inequality were relatively muted last year, our nowcast suggests that there was a pronounced rise in poverty (measured after housing costs[…]. The increase in overall poverty (from 22.1 to 23.2 per cent) was the largest since 1988. But this was dwarfed by the increase in child poverty, which rose from 30.3 per cent to 33.4 per cent. […]The fortunes of middle-income households diverged from those towards the bottom of the distribution and so a greater share of households, and children, found themselves below the poverty threshold.

A simple literature search on Scope (or even Google Scholar) shows that there has been a significant increase in the number of journal articles and reports in the last 10 years on this topic. We do talk more about the limitations of GDP, but we are still using it as the main measure of national economic performance.

Is it then time to stop focusing our attention on GDP growth exclusively and start considering broader metrics of social development? And what would such metrics look like? Both interesting questions that we will try to address in coming blogs.

Ten years ago, the financial crisis deepened and stock markets around the world plummeted. The trigger was the collapse of Lehman Brothers, the fourth-largest US investment bank. It filed for bankruptcy on September 15, 2008. This was not the first bank failure around that time. In 2007, Northern Rock in the UK (Aug/Sept 2007) had collapsed and so too had Bear Stearns in the USA (Mar 2008).

Initially there was some hope that the US government would bail out Lehmans. But when Congress rejected the Bank Bailout Bill on September 29, the US stock market fell sharply, with the Dow Jones falling by 7% the same day. This was mirrored in other countries: the FTSE 100 fell by 15%.

At the core of the problem was excessive lending by banks with too little capital. What is more, much of the capital was of poor quality. Many of the banks held securitised assets containing ‘sub-prime mortgage debt’. The assets, known as collateralised debt obligations (CDOs), were bundles of other assets, including mortgages. US homeowners had been lent money based on the assumption that their houses would increase in value. When house prices fell, homeowners were left in a position of negative equity – owing more than the value of their house. With many people forced to sell their houses, prices fell further. Mortgage debt held by banks could not be redeemed: it was ‘sub-prime’ or ‘toxic debt’.

Response to the crisis

The outcome of the financial crash was a series of bailouts of banks around the world. Banks cut back on lending and the world headed for a major recession.

Initially, the response of governments and central banks was to stimulate their economies through fiscal and monetary policies. Government spending was increased; taxes were cut; interest rates were cut to near zero. By 2010, the global economy seemed to be pulling out of recession.

However, the expansionary fiscal policy, plus the bailing out of banks, had led to large public-sector deficits and growing public-sector debt. Although a return of economic growth would help to increase revenues, many governments felt that the size of the public-sector deficits was too large to rely on economic growth.

As a result, many governments embarked on a period of austerity – tight fiscal policy, involving cutting government expenditure and raising taxes. Although this might slowly bring the deficit down, it slowed down growth and caused major hardships for people who relied on benefits and who saw their benefits cut. It also led to a cut in public services.

Expanding the economy was left to central banks, which kept monetary policy very loose. Rock-bottom interest rates were then accompanied by quantitative easing. This was the expansion of the money supply by central-bank purchases of assets, largely government bonds. A massive amount of extra liquidity was pumped into economies. But with confidence still low, much of this ended up in other asset purchases, such as stocks and shares, rather than being spent on goods and services. The effect was a limited stimulation of the economy, but a surge in stock market prices.

With wages rising slowly, or even falling in real terms, and with credit easy to obtain at record low interest rates, so consumer debt increased.

Lessons

So have the lessons of the financial crash been learned? Would we ever have a repeat of 2007–9?

On the positive side, financial regulators are more aware of the dangers of under capitalisation. Banks’ capital requirements have increased, overseen by the Bank for International Settlements. Under its Basel II and then Basel III regulations (see link below), banks are required to hold much more capital (‘capital buffers’). Some countries’ regulators (normally the central bank), depending on their specific conditions, exceed these the Basel requirements.

But substantial risks remain and many of the lessons have not been learnt from the financial crisis and its aftermath.

There has been a large expansion of household debt, fuelled by low interest rates. This constrains central banks’ ability to raise interest rates without causing financial distress to people with large debts. It also makes it more likely that there will be a Minsky moment, when a trigger, such as a trade war (e.g. between the USA and China), causes banks to curb lending and consumers to rein in debt. This can then lead to a fall in aggregate demand and a recession.

Total debt of the private and public sectors now amounts to $164 trillion, or 225% of world GDP – 12 percentage points higher than in 2009.

China poses a considerable risk, as well as being a driver of global growth. China has very high levels of consumer debt and many of its banks are undercapitalised. It has already experienced one stock market crash. From mid-June 2015, there was a three-week fall in share prices, knocking about 30% off their value. Previously the Chinese stock market had soared, with many people borrowing to buy shares. But this was a classic bubble, with share prices reflecting exuberance, not economic fundamentals.

Although Chinese government purchases of shares and tighter regulation helped to stabilise the market, it is possible that there may be another crash, especially if the trade war with the USA escalates even further. The Chinese stock market has already lost 20% of its value this year.

Then there is the problem with shadow banking. This is the provision of loans by non-bank financial institutions, such as insurance companies or hedge funds. As the International Business Times article linked below states:

A mind-boggling study from the US last year, for example, found that the market share of shadow banking in residential mortgages had rocketed from 15% in 2007 to 38% in 2015. This also represents a staggering 75% of all loans to low-income borrowers and risky borrowers. China’s shadow banking is another major concern, amounting to US$15 trillion, or about 130% of GDP. Meanwhile, fears are mounting that many shadow banks around the world are relaxing their underwriting standards.

Another issue is whether emerging markets can sustain their continued growth, or whether troubles in the more vulnerable emerging-market economies could trigger contagion across the more exposed parts of the developing world and possibly across the whole global economy. The recent crises in Turkey and Argentina may be a portent of this.

Then there is a risk of a cyber-attack by a rogue government or criminals on key financial insitutions, such as central banks or major international banks. Despite investing large amounts of money in cyber-security, financial institutions worry about their vulnerability to an attack.

Any of these triggers could cause a crisis of confidence, which, in turn, could lead to a fall in stock markets, a fall in aggregate demand and a recession.

Finally there is the question of the deep and prolonged crisis in capitalism itself – a crisis that manifests itself, not in a sudden recession, but in a long-term stagnation of the living standards of the poor and ‘just about managing’. Average real weekly earnings in many countries today are still below those in 2008, before the crash. In Great Britain, real weekly earnings in July 2018 were still some 6% lower than in early 2008.

Would you start a family if you were pessimistic about the future of the economy? Buckles et al (2017) (see link below) believe that fewer of us would do so and, therefore, fertility rates could be used by investors and central banks as an early signal to pick up subtle changes in consumer confidence and overall economic climate.

Their study titled ‘Fertility is a leading economic indicator’ uses ‘live births’ data, sourced from US birth certificates, to explore if there is any association between fertility changes (measured as the rate of change in number of births) and GDP growth. Their results suggest that, in the case of the USA, there is: dips in fertility rates tend to precede by several quarters slowdown in economic activity. As the authors state:

The growth rate of conceptions declines prior to economic downturns and the decline occurs several quarters before recessions begin. Our measure of conceptions is constructed using live births; we present evidence suggesting that our results are indeed driven by changes in conceptions and not by changes in abortion or miscarriage. Conceptions compare well with or even outperform other economic indicators in anticipating recessions.

Conception and GDP Growth Rates (source Buckles et al p33: see below)

Although this is not the first piece of academic writing to claim that fertility has pro-cyclical qualities (see for instance, Adsera (2004, 2011), Adsera and Menendez (2011), Currie and Schwandt (2014) and Chatterjee and Vogle (2016) linked below), it is, to the best of our knowledge, the most recent paper (in terms of data used) to depict this relationship and to explore the suitability of fertility as a macroeconomic indicator to predict recessions.

Economies, after all, are groups of people who participate actively in day-to-day production and consumption activities – as consumers, workers and business leaders. Changes in their environment should affect their expectations about the future.

Are people, however, forward-looking enough to guide their current behaviours by their expectations of future economic outcomes? They may be, according to the findings of this study.

Did you know, for instance, that sales of ties tend to increase in economic downturns, as men buy more ties to show that they are working harder, in fear of losing their job[1]? But this is probably a topic for another blog.

  1. Give two reasons why fertility rates may be a good indicator of economic activity.
  2. Give two reasons why fertility rates may NOT be a good indicator of economic activity.
  3. Do a literature search to identify and explain an ‘unorthodox’ macroeconomic indicator of your choice, and how it has been used to track economic activity.

[1] A brief description of other ‘unorthodox’ trackers of economic activity can be found in this Business Insider article: “54 bizarre ways to track the economy”

On 8 February, the Bank of England issued a statement that was seen by many as a warning for earlier and speedier than previously anticipated increases in the UK base rate. Mark Carney, the governor of the Bank of England, referred in his statement to ‘recent forecasts’ which make it more likely that ‘monetary policy would need to be tightened somewhat earlier and by a somewhat greater extent over the forecast period than anticipated at the time of the November report’.

A similar picture emerges on the other side of the Atlantic. With labour markets continuing to deliver spectacularly high rates of employment (the highest in the last 17 years), there are also now signs that wages are on an upward trajectory. According to a recent report from the US Bureau of Labor Statistics, US wage growth has been stronger than expected, with average hourly earnings rising by 2.9 percent – the strongest growth since 2009.

These statements have coincided with a week of sharp corrections and turbulence in the world’s largest capital markets, as investors become increasingly conscious of the threat of rising inflation – and the possibility of tighter monetary policy.

The Dow Jones plunged from an all-time high of 26,186 points on 1 February to 23,860 a week later – losing more than 10 per cent of its value in just five trading sessions (suffering a 4.62 percentag fall on 5 February alone – the worst one-day point fall since 2011). European and Asian markets followed suit, with the FTSE-100, DAX and NIKKEI all suffering heavy losses in excess of 5 per cent over the same period.

But why should higher inflationary expectations fuel a sell-off in global capital markets? After all, what firm wouldn’t like to sell its commodities at a higher price? Well, that’s not entirely true. Investors know that further increases in inflation are likely to be met by central banks hiking interest rates. This is because central banks are unlikely to be willing or able to allow inflation rates to rise much above their target levels.

The Bank of England, for instance, sets itself an inflation target of 2%. The actual ongoing rate of inflation reported in the latest quarterly Inflation Report is 3% (50 per cent higher than the target rate).

Any increase in interest rates is likely to have a direct impact on both the demand and the supply side of the economy.

Consumers (the demand side) would see their cost of borrowing increase. This could put pressure on households that have accumulated large amounts of debt since the beginning of the recession and could result in lower consumer spending.

Firms (the supply side) are just as likely to suffer higher borrowing costs, but also higher operational costs due to rising wages – both of which could put pressure on profit margins.

It now seems more likely that we are coming towards the end of the post-2008 era – a period that saw the cost of money being driven down to unprecedentedly low rates as the world’s largest economies dealt with the aftermath of the Great Recession.

For some, this is not all bad news – as it takes us a step closer towards a more historically ‘normal’ equilibrium. It remains to be seen how smooth such a transition will be and to what extent the high-leveraged world economy will manage to keep its current pace, despite the increasingly hawkish stance in monetary policy by the world’s biggest central banks.

These are challenging times for business. Economic growth has weakened markedly over the past 18 months with output currently growing at an annual rate of around 1.5 per cent, a percentage point below the long-term average. Spending power continues to be squeezed, with the annual rate of inflation in October reported to be running at 3.1 per cent compared to annual earnings growth of 2.5 per cent (see the squeeze continues). Moreover, consumer confidence remains fragile with households continuing to express particular concerns about the general economy and unemployment.

Here, we update our blog of July 2016 which, following the UK vote to leave the European Union, noted the fears for UK growth as confidence fell sharply. Consumer confidence is frequently identified by macro-economists as an important source of economic volatility. Indeed many macro models use a change in consumer confidence as a means of illustrating how economic shocks affect a range of macro variables, including growth, employment and inflation. Many economists agree that, in the short term at least, falling levels of confidence adversely affect activity because aggregate demand falls as households spend less.

The European Commission’s confidence measure is collated from questions in a monthly survey. In the UK around 2000 individuals are surveyed. Across the EU as a whole over 41 000 people are surveyed. In the survey individuals are asked a series of 12 questions which are designed to provide information on spending and saving intentions. These questions include perceptions of financial well-being, the general economic situation, consumer prices, unemployment, saving and the undertaking of major purchases.

The responses elicit either negative or positive responses. For example, respondents may feel that over the next 12 months the financial situation of their household will improve a little or a lot, stay the same or deteriorate a little or a lot. A weighted balance of positive over negative replies can be calculated. The balance can vary from -100, when all respondents choose the most negative option, to +100, when all respondents choose the most positive option.

The European Commission’s principal consumer confidence indicator is the average of the balances of four of the twelve questions posed: the financial situation of households, the general economic situation, unemployment expectations (with inverted sign) and savings, all over the next 12 months. These forward-looking balances are seasonally adjusted. The aggregate confidence indicator is thought to track developments in households’ spending intentions and, in turn, likely movements in the rate of growth of household consumption.

Chart 1 shows the consumer confidence indicator for the UK. The long-term average of –8.6 shows that negative responses across the four questions typically outweigh positive responses. In November 2017 the confidence balance stood at -5.2 roughly on par with its value in the previous two months, though marginally up on values of close to -7 over the summer. However, as recently as the beginning of 2016 the aggregate confidence score was running at around +4. In this context, current levels do constitute a significant change in consumer sentiment, changes which do ordinarily mark similar turning points in economic activity.(Click here to download a PowerPoint of the chart.)

Chart 2 allows to look behind the European Commission’s headline confidence indicator for the UK by looking at its four component balances. From it, we can see a deterioration in all four components. However, by far the most significant change in the individual confidence balances has been the sharp deterioration in expectations for the general economy. In November the forward-looking general economic situation stood at -25.5, compared to its long-run average of -11.6. (Click here to download a PowerPoint of the chart.)

The fall in UK consumer confidence is even more stark when compared to developments in consumer confidence across the whole of the European Union and in the 19 countries that make up the Euro area. Chart 3 shows how UK consumer confidence recovered relatively more strongly following the financial crisis of the late 2000s. The headline confidence indicator rose strongly from the middle of 2013 and was consistently in positive territory during 2014, 2015 and into 2016. The fall in consumer confidence in the UK has seen the headline confidence measure fall below that for the EU and the euro area. (Click here to download a PowerPoint of the chart.)

Consumer (and business) confidence is closely linked to uncertainty. The circumstances following the UK vote to leave the EU have undoubtedly created the conditions for acute uncertainty. Uncertainty breeds caution. Economists sometimes talk about spending being affected by two conflicting motives: prudence and impatience. While impatience creates a desire for spending now, prudence pushes us towards saving and insuring ourselves against uncertainty and unforeseen events. The worry is that the twin forces of fragile confidence and squeezed real earning are weighting heavily in favour of prudence and patience (a reduction in impatience). Going forward, this could create the conditions for a sustained period of subdued growth which, if it were to impact heavily on firms’ investment plans, could adversely impact on the economy’s productive potential. The hope is that the Brexit negotiations can move apace to reduce uncertainty and limit uncertainty’s adverse impact on economic activity.
