Politicians often make use of economic statistics to promote their point of view. A good example is a claim made by the UK Prime Minister on 23 January 2014. According to the latest statistics, he said, most British workers have seen their take-home pay rise in real terms. The Labour party countered this by arguing that incomes are not keeping up with prices.

So who is right? Studying economics and being familiar with analysing economic data should help you answer this question. Not surprisingly, the answer depends on just how you define the issue and what datasets you use.

The Prime Minister was referring to National Statistics’ Annual Survey of Hours and Earnings (ASHE). This shows that in April 2013 median gross weekly earnings for full-time employees were £517.5, up 2.25% from £506.10 in 2012, and mean gross weekly earnings for full-time employees were £620.30, up 2.06% from £607.80 in 2012 (see Table 1.1a in the dataset). CPI inflation over this period was 2.4%, representing a real fall in median gross weekly earnings of 0.15% and mean gross weekly earnings of 0.34%.

But when adjustments are made for increases in personal income tax allowances, then, according to the government, except for the richest 10% of the working population, people had an average increase in real take-home pay of 1.1%.

But does this paint the complete picture? Critics of the government’s claim that people are ‘better off’, make the following points.

First, the ASHE dataset is for the year ending April 2013. The ONS publishes other datasets that show that real wages have fallen faster since then. The Earnings and Working Hours datasets, published monthly, currently go up to November 2013. The chart shows real wages from January 2005 to November 2013 (with CPI = 100 in December 2013). You can see that the downward trend resumed after mid 2013. In the year to November 2013, nominal average weekly earnings rose by 0.9%, while CPI inflation was 2.1%. Thus real weekly earnings fell by 1.2% over the period (click here for a PowerPoint of the chart).

Second, there is the question of whether CPI or RPI inflation should be used in calculating real wages. RPI inflation was 2.9% (compared to CPI inflation of 2.4%) in the year to April 2013. The chart shows weekly earnings adjusted for both CPI and RPI.

Third, if, instead of looking at gross real wages, the effect of income tax and national insurance changes are taken into account, then benefit changes ought also to be taken into account. Some benefits, such as tax credits and child benefit were cut in the year to April 2013.

Fourth, looking at just one year (and not even the latest 12 months) gives a very partial picture. It is better to look at a longer period and see what the trends are. The chart shows the period from 2005. Real wages (CPI adjusted) are 8.0% lower than at the peak (at the beginning of 2009) and 5.0% lower than at the time of the election in 2010. The differences are even greater if RPI-adjusted wages are used.

But even if the claim that real incomes are rising is open to a number of objections, it may be that as the recovery begins to gather pace, real incomes will indeed begin to rise. But to assess whether this is so will require a careful analysis of the statistics when they become available.

World leaders are meeting at the World Economic Forum in Davos, in the Swiss Alps. This annual conference is an opportunity for politicans, economists and businesspeople from around the world to discuss the state of the world economy and to consider policy options.

To coincide with the conference, the BBC’s Newsnight has produced the following slide show, which presents some economic facts about the world economy. The slide show provides no commentary and there is no commentary either in this blog – just some questions for you to ponder.

Using the economics you’ve learned so far, try answering these questions, which focus on the reasons for the patterns in the figures, the likely future patterns and the policy implications.

When the rest of the developed world went into recession after the financial crisis of 2007/8, the Australian economy kept growing, albeit at a slightly lower rate (see chart 1: click here for a PowerPoint). Then as the world economy began to grow again after 2009, Australian grow accelerated. Partly this was the result of a strong growth in demand for Australian mineral exports, such as coal, iron ore and bauxite, especially from China and other east Asian countries.

But in 2013, Australian growth slowed and jobs grew by their lowest rate for 17 years. Employment actually fell by 22,600 in December and unemployment was only prevented from rising by a fall in the participation rate. The Australian dollar, which has been depreciating in recent months, fell further on the news about jobs, reaching its lowest level for over two years (see chart 2: click here for a PowerPoint).

The following articles look at the reasons behind Australia’s slowing growth and at possible reactions of the Australian government and the Reserve Bank of Australia (Australia’s central bank). They also look at the link between economic performance and policy on the one hand and the exchange rate on the other.

A recession is typically characterised by high unemployment, low or negative growth and low inflation, due to a lack of aggregate demand. However, since 2009, inflation levels in the UK have only added to the pressures facing the government and the Bank of England. Not only had there been a problem of lack of demand, but the inflation target was no longer being met.

Inflation had increased to above 5% – a figure we had not been accustomed to for many years. With interest rates at record lows with the aim of boosting aggregate demand, demand-pull inflation only added to cost-push pressures. However, data released by the ONS shows that inflation, as measured by the CPI, has now fallen back to its 2% target. Having been at 2.1% in November 2013, the figure for December 2013 fell by 0.1 percentage points.

The data for December include some of the energy price rises from the big six, but do not include the full extent of price decreases and discounting initiated by retailers in the lead up to Christmas. The key factors that have helped to keep prices down include some of the discounting throughout December and falling food prices, in particular bananas, grapes and meat.

With inflation back on target, pressures have been removed from the Bank of England to push up interest rates. Mark Carney has said that interest rates will remain at 0.5% until unemployment falls to 7%. With unemployment fast approaching this target, there has been speculation that interest rates would rise, but with inflation falling back on target, these pressures have been reduced. (Click here for a PowerPoint of the chart.) Referring to this, Jeremy Cook, the chief economist at World First said:

The lack of inflation will help stay their hand especially if the pace of job creation seen in the second half of last year also shows.

These thoughts were echoed by Rob Wood, the chief UK economist at Berenberg Bank:

Inflation is the BoE’s ‘get out of jail free’ card for this year … The lack of inflation pressure gives them room to delay a first hike until next year.

Many economists now believe that the CPI rate of inflation is likely to remain at or below the target, in particular if productivity growth improves. This belief is further enhanced by the fact that tax rates are stable, the pound is relatively strong and the previous upward pressure on commodity prices from China is now declining. Some economists believe that CPI inflation could fall to 1.5% this year and the Treasury has said that it is ‘another sign that the Government’s long-term economic plan is working’. The following articles consider this latest macroeconomic data.

Questions

  1. What is the relationship between interest rates and aggregate demand?
  2. Which factors have led to the reduction in the rate of inflation?
  3. Why have the latest data on inflation rates reduced the pressure on the Bank of England to increase interest rates?
  4. Why do stable tax rates, a strong pound and reduced pressure from China on commodity prices suggest that the CPI measures of inflation is likely to remain at similarly low levels?
  5. Why has the RPI increased while the CPI has fallen?

Conservative Party leaders are considering the benefits of an above-inflation rise in the minimum wage. This policy has been advocated by both the Labour Party and the Liberal Democrats as a means of helping the lowest paid workers. From 2008 to 2013, minimum wage rates fell 5.2% in real terms: in other words, nominal increases were less than the increase in both the RPI and CPI (see UK minimum wage: a history in numbers).

Advocates of a real rise in the minimum wage argue that not only would it help low-paid workers, many of whom are in severe financial difficulties, but it would benefit the Treasury. According to Policy Exchange, a free-market think tank closely aligned to the Conservative Party, increasing the minimum wage by 50p would save the Government an estimated £750m a year through higher tax revenues and lower benefit payments.

But even such a rise to £6.81 would still leave the minimum wage substantially below the living wage of £8.80 in London and £7.65 in the rest of the UK, as estimated by the Living Wage Foundation (see The cost of a living wage). Although many businesses are now paying at least the living wage, many others, especially small businesses, argue that a rise in the minimum wage above the rate of inflation would force them to consider cutting the number of employees or reducing hours for part-time workers.

Meanwhile, in the USA 13 states have raised their minimum wage rates from the 1st January 2014 (see). Some of the rises, however, were tiny: as little as 15 cents. In a couple of cases, the rise is $1. Currently 21 states and DC have minimum wage rates above the Federal level of $7.25 (approx. £4.40); 20 states have rates the same as the Federal level; 4 states have rates below the Federal level. At $9.32 per hour, Washington State has the highest state minimum wage; the lowest rates ($5.15) are in Georgia and Wyoming. In 5 states there is no minimum wage at all. As the ABC article below states:

The piecemeal increases at the local level are occurring amidst a national debate over low wages and income inequality. Fast food and retail workers have been staging protests and walking off work for more than a year, calling for better pay and more hours. Currently, fast food workers nationally earn an average of about $9 per hour.

Workers from McDonald’s, Wendy’s, Burger King and other fast food joints are calling for $15 per hour. Wal-Mart workers organizing as part of the union-backed OUR Walmart aren’t asking for a specific dollar amount increase, but they say it’s impossible to live on the wages they currently receive.

President Obama has been throwing his weight behind the issue. Earlier this month, the President said in a speech that it’s “well past the time to raise the minimum wage that in real terms right now is below where it was when Harry Truman was in office.” But such legislation has a bleaker outlook if it reaches the Republican-led House of Representatives. House Speaker John Boehner has said that raising the minimum wage leads to a pullback in hiring.

So what are the costs and benefits of a significant real rise is the minimum wage on either side of the Atlantic? The articles explore the issues.
