With the effects of the depreciation of sterling feeding through into higher prices, so the rate of inflation has risen. The latest figures from the ONS show that in the year to April 2017, CPI inflation was 2.7% – up from 2.3% in the year to March. The largest contributors to higher prices were transport costs and housing and household services.
But wage increases are not keeping up with price increases. In 2017 Q1, the average annual growth rate in regular pay (i.e. excluding bonuses) was 2.1%. In other words, real pay is falling. And this is despite the fact that the unemployment rate, at 4.6%, is the lowest since 1975.
The fall in real wages is likely to act as a brake on consumption and the resulting dampening of aggregate demand could result in lower economic growth. On the other hand, the more buoyant world economy, plus the lower sterling exchange rate is helping to boost exports and investment and this could go some way to offsetting the effects on consumption. As Mark Carney stated in his introductory remarks to the May 2017 Bank of England Inflation Report:
The combination of the stronger global outlook and sterling’s past depreciation is likely to support UK net trade. And together with somewhat lower uncertainty, stronger global growth is also likely to encourage investment as exporters renew and increase capacity.
According to the Bank of England, the net effect will be modest economic growth, despite the fall in real wages.
In the MPC’s central forecast, quarterly growth is forecast to stabilise around its current rate, resulting in growth of 1.9% in 2017 and around 1¾% in each of the next two years.
But forecasting is dependent on a range of assumptions, not least of which are assumptions about consumer and business expectations. These, in turn, depend on a whole range of factors, such as the outcome of the UK election, the Brexit negotiations, commodity prices, world growth rates and international events, such as the actions of Donald Trump. Because of the uncertainty surrounding forecasts, the Bank of England uses fan charts. In the two fan charts illustrated below (from the May 2017 Inflation Report), the bands on constructed on the following assumptions:
If economic circumstances identical to today’s were to prevail on 100 occasions, the MPC’s best collective judgement is that CPI inflation or the mature estimate of GDP growth would lie within the darkest central band on only 30 of those occasions and within each pair of the lighter coloured areas on 30 occasions.

The charts and tables showing the May 2017 projections have been conditioned on the assumptions that the stock of purchased gilts remains at £435 billion and the stock of purchased corporate bonds remains at £10 billion throughout the forecast period, and on the Term Funding Scheme (TFS); all three of which are financed by the issuance of central bank reserves. They have also been conditioned on market interest rates, unless otherwise stated.
The wider the fan, the greater the degree of uncertainty. These fan charts are wide by historical standards, reflecting the particularly uncertain future for the UK economy.
But one thing is clear from the latest data: real incomes are falling. This is likely to dampen consumer spending, but just how much this will impact on aggregate demand over the coming months remains to be seen.

One of President Trump’s main policy slogans has been ‘America first’. As Trump sees it, a manifestation of a country’s economic strength is its current account balance. He would love the USA to have a current account surplus. As it is, it has the largest current account deficit in the world (in absolute terms) of $481 billion in 2016 or 2.6% of GDP. This compares with the UK’s $115bn or 4.4% of GDP. Germany, by contrast, had a surplus in 2016 of $294bn or 8.5% of GDP.
However, he looks at other countries’ current account surpluses suspiciously – they may be a sign, he suspects, of ‘unfair play’. Germany’s surplus of over $50bn with the USA is particularly in his sights. Back in January, as President-elect, he threatened to put a 35% tariff on imports of German cars.
In practice, Germany is governed by eurozone rules, which prevent it from subsidising exports. And it does not have its own currency to manipulate. What is more, it is relatively open to imports from the USA. The EU imposes an average tariff of just 3% on US imports and importers also have to add VAT (19% in the case of Germany) to make them comparably priced with goods produced within the EU.
So why does Germany have such a large current account surplus? The article below explores the question and dismisses the claim that it’s the result of currency manipulation or discrimination against imports. The article states that the reason for the German surplus is that:
… it saves more than it invests. The correspondence of savings minus investment with exports minus imports is not an economic theory; it’s an accounting identity. Germans collectively spend less than they produce, and the difference necessarily shows up as net exports.
But why do the Germans save so much? The answer given is that, with an aging population, Germans are sensibly saving now to support themselves in old age. If Germany were to reduce its current account surplus, this would entail either the government reducing its budget surplus, or people reducing the amount they save, or some combination of the two. This is because a current account surplus, which consists of exports and other incomes from abroad (X) minus imports and any other income flowing abroad (M), must equal the surplus of saving (S) plus taxation (T) over investment (I) plus government expenditure (G). In terms of withdrawals and injections, given that:
I + G + X = S + T + M
then, rearranging the terms,
X – M = (S + T) – (I + G).
If German people are reluctant to reduce the amount they save, then an alternative is for the German government to reduce taxation or increase government expenditure. In the run-up to the forthcoming election on 24 September, Chancellor Merkel’s centre-right CDU party advocates cutting taxes, while the main opposition party, the SPD, advocates increasing government expenditure, especially on infrastructure. The article considers the arguments for these two approaches.

The latest figures from the ONS show that UK inflation rose to 2.3% for the 12 months to February 2017 – up from 1.9% for the 12 months to January. The rate is the highest since September 2013 and has steadily increased since late 2015.
The main price index used to measure inflation is now CPIH, as opposed to CPI. CPIH is the consumer prices index (CPI) adjusted for housing costs and is thus a more realsitic measure of the cost pressures facing households. As the ONS states:
CPIH extends the consumer prices index (CPI) to include a measure of the costs associated with owning, maintaining and living in one’s own home, known as owner occupiers’ housing costs (OOH), along with Council Tax. Both of these are significant expenses for many households and are not included in the CPI.
But why has inflation risen so significantly? There are a number of reasons.
The first is a rise in transport costs (contributing 0.15 percentage points to the overall inflation rate increase of 0.4 percentage points). Fuel prices rose especially rapidly, reflecting both the rise in the dollar price of oil and the depreciation of the pound. In February 2016 the oil price was $32.18; in February 2017 it was $54.87 – a rise of 70.5%. In February 2016 the exchange rate was £1 = $1.43; in February 2017 it was £1 = $1.25 – a depreciation of 12.6%.
The second biggest contributor to the rise in inflation was recreation and culture (contributing 0.08 percentage points). A wide range of items in this sector, including both goods and services, rose in price. ‘Notably, the price of personal computers (including laptops and tablets) increased by 2.3% between January 2017 and February 2017.’ Again, a large contributing factor has been the fall in the value of the pound. Apple, for example, raised its UK app store prices by a quarter in January, having raised prices for iPhones, iPads and Mac computers significantly last autumn. Microsoft has raised its prices by more than 20% this year for software services such as Office and Azure. Dell, HP and Tesla have also significantly raised their prices.
The third biggest was food and non-alcoholic beverages (contributing 0.06 percentage points). ‘Food prices, overall, rose by 0.8% between January 2017 and February 2017, compared with a smaller rise of 0.1% a year earlier.’ Part of the reason has been the fall in the pound, but part has been poor harvests in southern Europe putting up euro prices. This is the first time that overall food prices have risen for more than two-and-a-half years.
It is expected that inflation will continue to rise over the coming months as the effect of the weaker pound and higher raw material and food prices filter though. The current set of pressures could see inflation peaking at around 3%. If there is a futher fall in the pound or further international price increases, inflation could be pushed higher still – well above the Bank of England’s 2% target. (Click here for a PowerPoint of the chart.)
The higher inflation means that firms are facing a squeeze on their profits from two directions.
First, wage rises have been slowing and are now on a level with consumer price rises. It is likely that wage rises will soon drop below price rises, meaning that real wages will fall, putting downward pressure on spending and squeezing firms’ revenue.
Second, input prices are rising faster than consumer prices. In the 12 months to February 2017, input prices (materials and fuels) rose by 19.1%, putting a squeeze on producers. Producer prices (‘factory gate prices’), by contrast, rose by 3.7%. Even though input prices are only part of the costs of production, the much smaller rise of 3.7% reflects the fact that producer’s margins have been squeezed. Retailers too are facing upward pressure on costs from this 3.7% rise in the prices of products they buy from producers.
One of the worries about the squeeze on real wages and the squeeze on profits is that this could dampen investment and slow both actual and potential growth.
So will the Bank of England respond by raising interest rates? The answer is probably no – at least not for a few months. The reason is that the higher inflation is not the result of excess demand and the economy ‘overheating’. In other words, the higher inflation is not from demand-pull pressures. Instead, it is from higher costs, which are in themselves likely to dampen demand and contribute to a slowdown. Raising interest rates would cause the economy to slow further.

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.
