Economic forecasting came in for much criticism at the time of the financial crisis and credit crunch. Few economists had predicted the crisis and its consequences. Even Queen Elizabeth II, on a visit to the London School of Economics in November 2008, asked why economists had got it so wrong. Similar criticisms have emerged since the Brexit vote, with economic forecasters being accused of being excessively pessimistic about the outcome.
The accuracy of economic forecasts was one of the topics discussed by Andy Haldane, Chief Economist at the Bank of England. Speaking at the Institute for Government in London, he compared economic forecasting to weather forecasting (see section from 15’20” in the webcast):
“Remember that? Michael Fish getting up: ‘There’s no hurricane coming but it will be very windy in Spain.’ Very similar to the sort of reports central banks – naming no names – issued pre-crisis, ‘There is no hurricane coming but it might be very windy in the sub-prime sector.” (18’40”)
The problem with the standard economic models which were used for forecasting is that they were essentially equilibrium models which work reasonably well in ‘normal’ times. But when there is a large shock to the economic system, they work much less well. First, the shocks themselves are hard to predict. For example, the sub-prime crisis in 2007/8 was not foreseen by most economists.
Then there is the effect of the shocks. Large shocks are much harder to model as they can trigger strong reactions by consumers and firms, and governments too. These reactions are often hugely affected by sentiment. Bouts of pessimism or even panic can grip markets, as happened in late 2008 with the collapse of Lehman Brothers. Markets can tumble way beyond what would be expected by a calm adjustment to a shock.
It can work the other way too. Economists generally predicted that the Brexit vote would lead to a fall in GDP. However, despite a large depreciation of sterling, consumer sentiment held up better than was expected and the economy kept growing.
But is it fair to compare economic forecasting with weather forecasting? Weather forecasting is concerned with natural phenomena and only seeks to forecast with any accuracy a few days ahead. Economic forecasting, if used correctly, highlights the drivers of economic change, such as government policy or the Brexit vote, and their likely consequences, other things being equal. Given that economies are constantly being affected by economic shocks, including government or central bank actions, it is impossible to forecast the state of the macroeconomy with any accuracy.
This does not mean that forecasting is useless, as it can highlight the likely effects of policies and take into account the latest surveys of, say, consumer and business confidence. It can also give the most likely central forecast of the economy and the likely probabilities of variance from this central forecast. This is why many forecasts use ‘fan charts’: see, for example, Bank of England forecasts.
What economic forecasts cannot do is to predict the precise state of the economy in the future. However, they can be refined to take into account more realistic modelling, including the modelling of human behaviour, and more accurate data, including survey data. But, however refined they become, they can only ever give likely values for various economic variables or likely effects of policy measures.

In two recent speeches, the Governor of the Bank of England, Mark Carney, and the Bank’s Chief Economist, Andy Haldane, have reflected on the growing inequality in the UK and other countries. They have also answered criticisms that monetary policy has exacerbated the problem. As, Andy Haldane puts it:
It is clear monetary policy has played a material role in lifting all boats since the financial crisis broke. …[But] even if monetary policy has lifted all boats, and could plausibly do so again if needed, that does not mean it has done so equally. In particular, concerns have been expressed about the potential distributional effects of monetary policy.
Jan Vlieghe [member of the Monetary Policy Committee] has recently looked at how monetary policy may have affected the fortunes of, among others, savers, pension funds and pensioners. The empirical evidence does not suggest these cohorts have been disadvantaged to any significant degree by the monetary policy stance. For most members in each cohort, the boost to their asset portfolios and the improved wages and profits due to a stronger economy more than offset the direct loss of income from lower rates [of interest on savings accounts].
Andy Haldane’s speech focused largely on regional inequality. He argued that productivity has grown much more rapidly in the more prosperous regions, such as London and the South East. This has resulted in rising inequality in wages between different parts of the UK. Policies that focus on raising productivity in the less prosperous regions could play a major role in reducing income inequality.
Mark Carney’s speech echoed a lot of what Andy Haldane was saying. He argued that expansionary monetary policy has, according to Bank of England modelling, “raised the level of GDP by around 8% relative to trend and lowered unemployment by 4 percentage points at their peak”. And the benefits have been felt by virtually everyone. Even savers have generally gained:
That’s in part because, to a large extent, the thrifty saver and the rich asset holder are often one and the same. Just 2% of households have deposit holdings in excess of £5000, few other financial assets and don’t own a home.
But some people still gained more from monetary policy than others – enough to contribute to widening inequality.
Losers from the lost decade
Mark Carney looked beyond monetary policy and argued that the UK has experienced a ‘lost decade’, where real incomes today are little higher than 10 years ago – the first time this has happened for 150 years. This stalling of average real incomes has been accompanied by widening inequality between various groups, where a few have got a lot richer, especially the top 1%, and many have got poorer. Although the Gini coefficient has remained relatively constant in recent years, there has been a widening gap between the generations.
For both income and wealth, some of the most significant shifts have happened across generations. A typical millennial earned £8000 less during their twenties than their predecessors. Since 2007, those over 60 have seen their incomes rise at five times the rate of the population as a whole. Moreover, rising real house prices between the mid-1990s and the late 2000s have created a growing disparity between older home owners and younger renters.
This pattern has been repeated around the developed world and has led to disillusionment with globalisation and a rise in populism. Globalisation has been “associated with low wages, insecure employment, stateless corporations and striking inequalities”. (Click here for a PowerPoint of the chart.)
And populism has been reflected in the crisis in Greece, the Brexit vote, Donald Trump’s election, the rise of the National Front in France, the No vote in the Italian referendum on reforming the constitution and the rise in anti-establishment parties and sentiment generally. Mainstream parties are beginning to realise that concerns over globalisation, inequality and a sense of disempowerment must be addressed.
Solutions to inequality
As far as solutions are concerned, central must be a rise in general productivity that increases potential real income.
Boosting the determinants of long-run prosperity is the job of government’s structural, or supply-side policies. These government policies influence the economy’s investment in education and skills; its capacity for research and development; the quality of its core institutions, such as the rule of law; the effectiveness of its regulatory environment; the flexibility of its labour market; the intensity of competition; and its openness to trade and investment.
But will this supply-side approach be enough to bring both greater prosperity and greater equality? Will an openness to trade be accepted by populist politicians who blame globalisation and the unequal gains from international trade for the plight of the poor? Carney recognises the problem and argues that:
For the societies of free-trading, networked countries to prosper, they must first re-distribute some of the gains from trade and technology, and then re-skill and reconnect all of their citizens. By doing so, they can put individuals back in control.
For free trade to benefit all requires some redistribution. There are limits, of course, because of fiscal constraints at the macro level and the need to maintain incentives at the micro level. Fostering dependency on the state is no way to increase human agency, even though a safety net is needed to cushion shocks and smooth adjustment.
Redistribution and fairness also means turning back the tide of stateless corporations.
… Because technology and trade are constantly evolving and can lead to rapid shifts in production, the commitment to reskilling all workers must be continual.
In a job market subject to frequent, radical changes, people’s prospects depend on direct and creative engagement with global markets. Lifelong learning, ever-greening skills and cooperative training will become more important than ever.
But whether these prescriptions will be accepted by people across the developed world who feel that the capitalist system has failed them and who look to more radical solutions, whether from the left or the right, remains to be seen. And whether they will be adopted by governments is another question!
