According to the theory of the political business cycle, governments call elections at the point in the business cycle that gives them the greatest likelihood of winning. This is normally near the peak of the cycle, when the economic news is currently good but likely to get worse in the medium term. With fixed-term governments, this makes it harder for governments as, unless they are lucky, they have to use demand management policies to engineer a boom as an election approaches. It is much easier if they can choose when to call an election.

In the UK, under the Fixed-term Parliaments Act of 2011, the next election must be five years after the previous one. This means that the next election in the UK must be the first Thursday in May 2020. The only exception is if at least two-thirds of all MPs vote for a motion ‘That there shall be an early parliamentary general election’ or ‘That this House has no confidence in Her Majesty’s Government.’

The former motion was put in the House of Commons on 19 April and was carried by 522 votes to 13 – considerably more than two-thirds of the 650 seats in Parliament. The next election will therefore take place on the government’s chosen date of 8 June 2017.

Part of the reason for the government calling an election is to give it a stronger mandate for its Brexit negotiations. Part is to take advantage of its currently strong opinion poll ratings, which, if correct, will mean that it will gain a substantially larger majority. But part could be to take advantage of the current state of the business cycle.

Although the economy is currently growing quite strongly (1.9% in 2016) and although forecasts for economic growth this year are around 2%, buoyed partly by a strongly growing world economy, beyond that things look less good. Indeed, there are a number of headwinds facing the economy.

First there are the Brexit negotiations, which are likely to prove long and difficult and could damage confidence in the economy. There may be adverse effects on both inward and domestic investment and possible increased capital outflows. At the press conference to the Bank of England’s February 2017 Inflation Report, the governor stated that “investment is expected to be around a quarter lower in three years’ time than projected prior to the referendum, with material consequences for productivity, wages and incomes”.

Second, the fall in the sterling exchange rate is putting upward pressure on inflation. The Bank of England forecasts that CPI inflation will peak at around 2.8% in early 2018. With nominal real wages lagging behind prices, real wages are falling and will continue to do so. As well as from putting downward pressure on living standards, it will tend to reduce consumption and the rate of economic growth.

Consumer debt has been rising rapidly in recent months, with credit-card debt reaching an 11-year high in February. This has helped to support growth. However, with falling real incomes, a lack of confidence may encourage people to cut back on new borrowing and hence on spending. What is more, concerns about the unsustainability of some consumer debt has encouraged the FCA (the financial sector regulator) to review the whole consumer credit industry. In addition, many banks are tightening up on their criteria for granting credit.

Retail spending, although rising in February itself, fell in the three months to February – the largest fall for nearly seven years. Such falls are likely to continue.

So if the current boom in the economy will soon end, then, according to political business cycle theory, the government is right to have called a snap election.

Questions

  1. For what reasons might economic growth in the UK slow over the next two to three years?
  2. For what reasons might economic growth increase over the next two to three years?
  3. Why is forecasting UK economic growth particularly difficult at the present time?
  4. What does political business cycle theory predict about the behaviour of governments (a) with fixed terms between elections; (b) if they can choose when to call an election?
  5. How well timed is the government’s decision to call an election?
  6. If retail sales are falling, what other element(s) of aggregate demand may support economic growth in the coming months?
  7. How does UK productivity compare with that in other developed countries? Explain why.
  8. What possible trading arrangements with the EU could the UK have in a post-Brexit deal? Discuss their likelihood and their impact on economic growth?

Economists were generally in favour of the UK remaining in the EU and highly critical of the policy proposals of Donald Trump. And yet the UK voted to leave the EU and Donald Trump was elected.

People rejected the advice of most economists. Many blamed the failure of most economists to predict the 2007/8 financial crisis and to find solutions to the growing gulf between rich and poor, with the majority stuck on low incomes.

So to what extent are economists to blame for the rise in populism – a wave that could lead to electoral upsets in various European countries? The podcast below brings together economists and politicians from across the political spectrum. It is over an hour long and provides an in-depth discussion of many of the issues and the extent to which economists can provide answers.

Both the financial and goods markets are heavily influenced by sentiment. And such sentiment tends to be self-reinforcing. If consumers and investors are pessimistic, they will not spend and not invest. The economy declines and this further worsens sentiment and further discourages consumption and investment. Banks become less willing to lend and stock markets fall. The falling stock markets discourage people from buying shares and so share prices fall further. The despondency becomes irrational and greatly exaggerates economic fundamentals.

This same irrationality applies in a boom. Here it becomes irrational exuberance. A boom encourages confidence and stimulates consumer spending and investment. This further stimulates the boom via the multiplier and accelerator and further inspires confidence. Banks are more willing to lend, which further feeds the expansion. Stock markets soar and destabilising speculation further pushes up share prices. There is a stock market bubble.

But bubbles burst. The question is whether the current global stock market boom, with share prices reaching record levels, represents a bubble. One indicator is the price/earnings (PE) ratio of shares. This is the ratio of share prices to earnings per share. Currently the ratio for the US index, S&P 500, is just over 26. This compares with a mean over the past 147 years of 15.64. The current ratio is the third highest after the peaks of the early 2000s and 2008/9.

An alternative measure of the PE ratio is the Shiller PE ratio (see also). This is named after Robert Shiller, who wrote the book Irrational Exuberance. Unlike conventional PE ratios, which only look at average earnings over the past four quarters, the Shiller PE ratio uses average earnings over the past 10 years. “Because this factors in earnings from the previous ten years, it is less prone to wild swings in any one year.”

The current level of the Shiller PE ratio is 29.14, the third highest on record, this time after the period running up to the Wall Street crash of 1929 and the dot-com bubble of the late 1990s. The mean Shiller PE ratio over the past 147 years is 16.72.

So are we in a period of irrational exuberance? And are stock markets experiencing a bubble that sooner or later will burst? The following articles explore these questions.

Is too much expected of economists? When economic forecasts turn out to be wrong, as they often are, economists are criticised for having inaccurate or unrealistic models. But is this a fair criticism?

The following article by Richard Whittle from Manchester Metropolitan University looks at what economists can and cannot do. The article highlights two key problems for economic forecasting.

The first concerns human behaviour, which is influenced by a whole range of factors and can change very rapidly in response to changing circumstances. Moods of optimism or pessimism can quickly spread in response to a news item, such as measures announced by Donald Trump or latest data on growth or the housing market.

The second concerns the whole range of possible economic shocks. Such shocks, by their very nature, are hard to predict and can quickly make forecasts wrong. They could be a surprise election result, a surprise government policy change, a natural disaster, a war or a series of terrorist attacks. And these shocks, in turn, affect human behaviour. Consumption and investment may rise or fall as the events affect confidence and herd behaviour.

But is it a fair criticism of economics that it cannot foretell the future? Do economists, as the article says, throw up their hands and curse economics as a futile endeavour? Not surprisingly, the answer given is no! The author gives an analogy with medicine.

A doctor cannot definitely prevent illness, but can offer advice on prevention and hopefully offer a cure if you do get ill. This is the same for the work economists do.

Economists can offer advice on preventing crises or slowdowns but cannot definitively prevent them from happening. Economists can also offer robust advice on restoring growth, although when the advice is that the economy has grown too fast and should slow, it is often not welcomed by policy makers.

Helping understanding the various drivers in an economy and how humans are likely to respond to various incentives is a key part of what economists do. But making predictions with 100% certainty is asking too much of economists.

And just as medical professionals can predict that if you smoke, eat unhealthy food or take no exercise you are likely to be less healthy and die younger, but cannot say precisely when an individual will die, so too economists can predict that certain policy measures are likely to increase or decrease GDP or employment or inflation, but they cannot say precisely how much they will be affected.

As the article says, “the true value of the economist lies not in mystical fortune telling, but in achieving a better understanding of the nature of the economies in which we live and work.”
