Elections are times of peak deception. Political parties have several ways in which they can use data to persuade people to vote for them. At one extreme, they can simply make up ‘facts’ – in other words, they can lie. There have been various examples of such lies in the run-up to the UK general election of 12 December 2019. The linked article below gives some examples. But data can be used in other deceptive ways, short of downright lies.
Politicians can use data in two ways. First, statistics can be used to describe, explain and interpret the past. Second, they can be used as the basis of forecasts of the future effects of policies.
In terms of past data, one of the biggest means of deception is the selective use of data. If you are the party currently in power, you highlight the good news and ignore the bad. You do the reverse if you are currently in opposition. The data may be correct, but selective use of data can give a totally false impression of events.
In terms of forecast data, you highlight those forecasts, or elements of them, that are favourable to you and ignore those that are not.
Politicians rely on people’s willingness to look selectively at data. People want to see ‘evidence’ that reinforces their political views and prejudices. News media know this and happily do the same as politicians, selectively using data favourable to their political leanings. And it’s not just newspapers that do this. There are many online news sites that feed their readers with data supportive of their position. And there are many social media platforms, where people can communicate with people in their political ‘bubble’.
Genuine fact-checking sites can help, as can independent forecasters, such as the Institute for Fiscal Studies. But too many voters would rather only look at evidence, genuine or not, that supports their political point of view.
This can make life hard for economists who seek to explain the world with an open mind, based on a non-biased use of evidence – and hard for economic forecasters, who want to use full and accurate data in their models and to make realistic assumptions, emphasising that their forecasts are only the most likely outcome, not a certainty. As the article states:
Economic forecasts are flawed and their limitations should be acknowledged. But they should not be blindly dismissed as fake facts. And as far as political debate and discourse is concerned, in the long run, the truth may will out.
- Give some specific examples of ways in which politicians misuse data.
- Give some specific examples of ways in which politicians misuse the analysis of economists.
- Distinguish between positive and normative statements? Should economists make policy recommendations? If so, in what context?
- Why are economic forecasts flawed, but why should they not be dismissed as ‘fake facts’?
- Examine the manifestos of two political parties and provide a critique of their economic analysis.
Economists are often criticised for making inaccurate forecasts and for making false assumptions. Their analysis is frequently dismissed by politicians when it contradicts their own views.
But is this fair? Have economists responded to the realities of the global economy and to the behaviour of people, firms, institutions and government as they respond to economic circumstances? The answer is a qualified yes.
Behavioural economics is increasingly challenging the simple assumption that people are ‘rational’, in the sense that they maximise their self interest by weighing up the marginal costs and benefits of alternatives open to them. And macroeconomic models are evolving to take account of a range of drivers of global growth and the business cycle.
The linked article and podcast below look at the views of 2019 Nobel Prize-winning economist Esther Duflo. She has challenged some of the traditional assumptions of economics about the nature of rationality and what motivates people. But her work is still very much in the tradition of economists. She examines evidence and sees how people respond to incentives and then derives policy implications from the analysis.
Take the case of the mobility of labour. She examines why people who lose their jobs may not always move to a new one if it’s in a different town. Partly this is for financial reasons – moving is costly and housing may be more expensive where the new job is located. Partly, however, it is for reasons of identity. Many people are attached to where they currently live. They may be reluctant to leave family and friends and familiar surroundings and hope that a new job will turn up – even if it means a cut in wages. This is not irrational; it just means that people are driven by more than simply wages.
Duflo is doing what economists typically do – examining behaviour in the light of evidence. In her case, she is revisiting the concept of rationality to take account of evidence on what motivates people and the way they behave.
In the light of workers’ motivation, she considers the implications for the gains from trade. Is free trade policy necessarily desirable if people lose their jobs because of cheap imports from China and other developing countries where labour costs are low?
The answer is not a clear yes or no, as import-competing industries are only part of the story. If protectionist policies are pursued, other countries may retaliate with protectionist policies themselves. In such cases, people working in the export sector may lose their jobs.
She also looks at how people may respond to a rise or cut in tax rates. Again the answer is not clear cut and an examination of empirical evidence is necessary to devise appropriate policy. Not only is there an income and substitution effect from tax changes, but people are motivated to work by factors other than take-home pay. Likewise, firms are encouraged to invest by factors other than the simple post-tax profitability of investment.
- In traditional ‘neoclassical’ economics, what is meant by ‘rationality’ in terms of (a) consumer behaviour; (b) producer behaviour?
- How might the concept of rationality be expanded to take into account a whole range of factors other than the direct costs and benefits of a decision?
- What is meant by bounded rationality?
- What would be the effect on workers’ willingness to work more or fewer hours as a result of a cut in the marginal income tax rate if (a) the income effect was greater than the substitution effect; (b) the substitution effect was greater than the income effect? Would your answers to (a) and (b) be the opposite in the case of a rise in the marginal income tax rate?
- Give some arguments that you consider to be legitimate for imposing controls on imports in (a) the short run; (b) the long run. How might you counter these arguments from a free-trade perspective?
When UK unemployment was 7.7% in July 2013, Mark Carney, the newly arrived governor of the Bank of England, said that the Bank would probably have to rise interest rates when the unemployment rate dropped below 7%. Below that rate, it was expected that inflation would rise. In other words, 7% was the NAIRU – the non-accelerating rate of inflation. The most recent figure for the unemployment rate is 4.8% and yet the Bank of England has not raised interest rates. In fact, in response to the Brexit vote, it cut Bank Rate from 0.5% to 0.25% in August last year. (Click here for a PowerPoint of the chart below.)
The NAIRU is a similar, although not identical, concept to the natural rate of unemployment. The natural rate is the equilibrium rate consistent with an overall long-term balance of aggregate labour demand and supply: i.e. the rate after short-term cyclical movements in unemployment have been discounted. It is thus a long-term concept.
The NAIRU, although similar, focuses on the relationship between inflation and unemployment. With inflation caused solely by demand-side factors, the natural rate and the NAIRU will be similar if not identical. However, if cost-push factors change – say there is a poor harvest, which pushes up food prices and inflation (temporarily), or a substantial depreciation of the exchange rate caused by political factors (such as Brexit) – the NAIRU would increase, at least in the short term, as a higher rate of unemployment would be necessary to stop inflation rising. In the long term, although being defined differently, the NAIRU and the natural rate will be the same.
In practice, because the Bank of England is targeting inflation at a 24-month time horizon, the NAIRU for the UK at that point could also be seen as the natural rate.
So with the Bank of England not raising interest rates despite the considerable fall in the unemployment rate, does this imply a fall in the natural rate of unemployment? The answer is yes. The reason has to do with changes in the structure of the labour market.
The proportion of young people and women with children returning to the labour market has fallen. Such people have a higher-than-average rate of unemployment since they typically spend a period of time searching for a job.
Tax and benefit reforms over the years have increased the incentive for the unemployed to take work.
Perhaps the biggest factor is a greater flexibility in the labour market. As union power has waned and as people are increasingly working on flexible contracts, including zero-hour contracts, so this has moderated wage increases. At the same time, many firms are facing increased competition both from abroad and domestically via the Internet. This has put downward pressure on prices and hence on the wages firms are willing to pay.
The effect has been a fall in the NAIRU and probably the natural rate. Frictions in the labour market have reduced and people losing their jobs because of changes in industrial structure find it easier to get jobs in low-skilled service industries, where employers’ risks of taking on such workers have fallen because of the loss of rights for such workers.
So what is the natural rate of unemployment today? It is certainly much lower than 7%; the consensus is that it is probably below 5%. As Kristin Forbes, External MPC Member of the Bank of England stated in a recent speech:
[Unemployment] is forecast to increase gradually from its current 4.8% to a high of 5.0% in the second half of 2017, before falling back to its current rate by the end of 2019. To put this in context, 5.0% was previously believed to be around the UK’s natural rate of unemployment – the rate below which unemployment could not fall without wages picking up to levels inconsistent with sustaining inflation around the 2% target. Unemployment at 5.0% is also below the average unemployment rate for the UK over the pre-crisis period from 1997 to 2007 (when it was 5.5%).
She went on to discuss just what the figure is for the natural, or ‘equilibrium’, rate of unemployment (U*). One problem here is that there is considerable uncertainty over the figure in the current forecast made by the Bank.
[An] assumption in the forecast about which there is substantial uncertainty is of the equilibrium unemployment rate – or U* for short. Since I have been on the MPC, the Committee has assumed that U* was around 5%. This implied that the more by which unemployment exceeded 5%, the more slack existed in the economy, and the less upward momentum would be expected in wages (controlling for other factors, such as productivity growth).
As part of our annual assessment of regular supply-side conditions this January, Bank staff presented several pieces of analysis that suggested U* may be lower than 5% today [see, for example]. The majority of the MPC voted to lower our estimate of U* to 4.5%, based partly on the persistent weakness of wage growth over the past few years after accounting for other factors in our models. [See page 20 of the February 2017 Inflation Report.]
My own assessment, however, suggested that although U* was likely lower than 5% today, it is likely not as low as 4.5%. If true, this would suggest that there is less slack in the economy than in the MPC’s central forecast, and wage growth and inflation could pick up faster than expected.
Against that, however, uncertainty related to Brexit negotiations could make firms more cautious about raising wages, thereby dampening wage growth no matter where unemployment is relative to its equilibrium. Moreover, even if we could accurately measure the level of U* in the economy today, it could easily change over the next few years as the labour force adjusts to any changes in the movement of labour between the UK and European Union.
Determining the precise figure of the current natural rate of unemployment, and predicting it for the medium term, is very difficult. It involves separating out demand-side factors, which are heavily dependent on expectations. It also involves understanding the wage elasticity of labour supply in various markets and how this has been affected by the increased flexibility of these markets.

We’ve considered Keynesian economics and policy in several blogs. For example, a year ago in the post, What would Keynes say?, we looked at two articles arguing for Keynesian expansionary polices. More recently, in the blogs, End of the era of liquidity traps? and A risky dose of Keynesianism at the heart of Trumponomics, we looked at whether Donald Trump’s proposed policies are more Keynesian than his predecessor’s and at the opportunities and risks of such policies.
The article below, Larry Elliott updates the story by asking what Keynes would recommend today if he were alive. It also links to two other articles which add to the story.
Elliott asks his imaginary Keynes, for his analysis of the financial crisis of 2008 and of what has happened since. Keynes, he argues, would explain the crisis in terms of excessive borrowing, both private and public, and asset price bubbles. The bubbles then burst and people cut back on spending to claw down their debts.
Keynes, says Elliott, would approve of the initial response to the crisis: expansionary monetary policy (both lower interest rates and then quantitative easing) backed up by expansionary fiscal policy in 2009. But expansionary fiscal policies were short lived. Instead, austerity fiscal policies were adopted in an attempt to reduce public-sector deficits and, ultimately, public-sector debt. This slowed down the recovery and meant that much of the monetary expansion went into inflating the prices of assets, such as housing and shares, rather than in financing higher investment.
He also asks his imaginary Keynes what he’d recommend as the way forward today. Keynes outlines three alternatives to the current austerity policies, each involving expansionary fiscal policy:
||Trump’s policies of tax cuts combined with some increase in infrastructure spending. The problems with this are that there would be too little of the public infrastructure spending that the US economy needs and that the stimulus would be poorly focused.
||Government taking advantage of exceptionally low interest rates to borrow to invest in infrastructure. “Governments could do this without alarming the markets, Keynes says, if they followed his teachings and borrowed solely to invest.”
||Use money created through quantitative easing to finance public-sector investment in infrastructure and housing. “Building homes with QE makes sense; inflating house prices with QE does not.” (See the blogs, A flawed model of monetary policy and Global warning).
Increased government spending on infrastructure has been recommended by international organisations, such as the OECD and the IMF (see OECD goes public and The world economic outlook – as seen by the IMF). With the rise in populism and worries about low economic growth throughout much of the developed world, perhaps Keynesian fiscal policy will become more popular with governments.

Some commentators have seen the victory of Donald Trump and, prior to that, the Brexit vote as symptoms of a crisis in capitalism. Much of the campaigning in the US election, both by Donald Trump on the right and Bernie Sanders on the left focused on the plight of the poor. Whether the blame was put on immigration, big government, international organisations, the banks, cheap imports undercutting jobs or a lack of social protection, the message was clear: capitalism is failing to improve the lot of the majority. A small elite is getting significantly richer while the majority sees little or no gain in their living standards and a rise in uncertainty.
The articles below look at this crisis. They examine the causes, which they agree go back many years as capitalism has evolved. The financial crash of 2008 and the slow recovery since are symptomatic of the underlying changes in capitalism.
The Friedman article focuses on the slowing growth in technological advance and the problem of aging populations. What technological progress there is is not raising incomes generally, but is benefiting a few entrepreneurs and financiers. General rises in income may eventually come, but it may take decades before robotics, biotechnological advances, e-commerce and other breakthrough technologies filter through to higher incomes for everyone. In the meantime, increased competition through globalisation is depressing the incomes of the poor and economically immobile.
All the articles look at the rise of the rich. The difference with the past is that the people who are gaining the most are not doing so from production but from financial dealing or rental income; they have gained while the real economy has stagnated.
The gains to the rich have come from the rise in the value of assets, such as equities (shares) and property, and from the growth in rental incomes. Only a small fraction of finance is used to fund business investment; the majority is used for lending against existing assets, which then inflates their prices and makes their owners richer. In other words, the capitalist system is moving from driving growth in production to driving the inflation of asset prices and rental incomes.
The process whereby financial markets grow and in turn drive up asset prices is known as ‘financialisation’. Not only is the process moving away from funding productive investment and towards speculative activity, it is leading to a growth in ‘short-termism’. The rewards of senior managers often depend on the price of their companies’ shares. This leads to a focus on short-term profit and a neglect of long-term growth and profitability – to a neglect of investment in R&D and physical capital.
The process of financialisation has been driven by deregulation, financial innovation, the growth in international financial flows and, more recently, by quantitative easing and low interest rates. It has led to a growth in private debt which, in turn, creates more financial instability. The finance industry has become so profitable that even manufacturing companies are moving into the business of finance themselves – often finding it more profitable than their core business. As the Foroohar article states, “the biggest unexplored reason for long-term slower growth is that the financial system has stopped serving the real economy and now serves mainly itself.”
So will the election of Donald Trump, and pressure from populism in other countries too, mean that governments will focus more on production, job creation and poverty reduction? Will there be a movement towards fiscal policy to drive infrastructure spending? Will there be a reining in of loose monetary policy and easy credit?
Or will addressing the problem of financialisation and the crisis of capitalism result in the rich continuing to get richer at the expense of the poor, but this time through more conventional channels, such as increased production and monopoly profits and tax cuts for the rich? Trump supporters from among the poor hope the answer is no. Those who supported Bernie Sanders in the Democratic primaries think the answer will be yes and that the solution to over financialisation requires more, not less, regulation, a rise in minimum wages and fiscal policies aimed specifically at the poor.
