1. How to perform well in the economics examinations (or how to avoid seven sins in examinations) by Peter Maunder , a former Chief Examiner

The football season is soon coming to a close with promotion and relegation issues to be resolved. Then we enter the examination season for AS and A2 candidates which differs from football being more of a “sudden-death” match with the examiners rather than a contest over many months. Candidates in economics examinations need to be on the ball in what they write for scrutiny by the examiners and not look overawed as can happen to players on the soccer field when playing in knock-out matches. They must not engage in foul play (such as with rubric infringement) or score own-goals (answering a question that was hoped-for rather than one on the examination paper).

How to get yourself fit for play ?

Given that the Easter holiday is past it seems too late to give advice such as how best to use that period of time to revise but what you can still usefully do is to have a look at the specification of your examination board to see how all your revision notes match what the examiners have set as the field of play. The spec is in effect “the fixture list”. You need to feel “at home” with as many parts of the spec as you can given that questions are possible on any part of that list.

Let us now come to the methods of assessment and try to give some match-day advice .

Answering essays

Essay questions seek to test the so-called higher-order skills of comprehension, analysis and evaluation. Responses need to offer a clear sense of direction that the examiner will recognise and is related to the question as set. The advice given by William Westgate in the March issue of Economics Today should be read again to remind you that you offer a logical flow of the argument offered to the examiner.(1)

Some key points to bear in mind :-

1. What is the key word directing the nature of the response required? Does it say “Explain…”, “Account for...” or “To what extent…“.

2. Are you required to give specific examples to illustrate theoretical concepts?

3. Are you required to give a judgement on something where empirical evidence is available?

Virtuous conduct in the examination room would note these aspects but let me try to help more effectively by spelling out what is bad conduct responding to essay questions. What is the equivalent of the yellow card for a foul tackle in football when in the exam room? What are what one might call the cardinal sins of examinations to avoid? I suggest that three sins relating to essay questions are illegibility, elusiveness and imbalance.

  • Illegibility. Don’t try to emulate the doctor’s prescription note as (s)he has the advantage that the local chemist regularly recognises the apparent undecipherable writing of a medic. You as a candidate are unknown to the examiner so don’t write in tiny hand-writing or in pale blue ink that irritates the examiner in trying to interpret the story you are offering.
  • Elusiveness. Don’t appear (more than you can hide) that you are in barely disguised discomfort handling the question set. You cannot evade making a clear definition of an economic term if one is sought. Pleading exam time pressure is not a credible alibi. For example this examiner was not impressed reading “This is a brief definition of money because I haven’t got much time left”.
  • Imbalance. If the question asks for a judgement on the relevant topic one cannot expect to “score” if one fails to adequately weigh up the pros and cons of the debate. If you see the key words “To what extent” you have a clear direction to review conflicting viewpoints/evidence and need to come to a conclusion as seems appropriate.

Answering data response questions

Virtuous conduct with such questions is easy to spell out. Whether in prose passage or numerical form data response material seeks to establish your ability to identify key relationships between variables and analyse causes of changes in the data (or maybe the consequences of changes in the data ). You may be asked to offer some evaluation of whether what is given is what you would have expected in the light of economic theory. To achieve these requirements you need to be clear what numerical data means e.g. is it in nominal or real terms? What type of relationship between two variables would you expect?Is it direct or indirect? Is it instant or lagged? Is there something not given to you on the exam paper which is the key variable to understanding the existing data provided?

What are two sins to avoid in handling data response material? I suggest two– irrelevance and long-windedness.

  • Irrelevance. If you are confronted by tabular data don’t focus on the minutiae but “stand back” to try to see the big picture. You may be asked for some calculation but don’t expect a long series of calculations is likely to be involved when there is a time constraint for the exam paper as a whole.
  • Long-windedness. This sin is often the consequence of irrelevancy. If one sets off concentrating on the minutiae of statistical data then one is in danger of then giving a blow by blow account of such mechanical calculations as to miss identifying the trends in data and changes in its composition. Always note the mark base as a guide as to the depth of the answer the examiner expects from you in the time available.

Answering Multiple Choice questions

Here it is easiest to comment of the sins to avoid rather than spell out virtuous conduct. But the latter amounts in essence to reasoning through the plausibility of each of the statements and eliminating one by one. Apply the logic of Sherlock Holmes – “ when you have eliminated the impossible, whatever remains, however improbable, must be the right answer”(2)

The sins to avoid are guesswork and unpreparedness.

  • Guesswork. Don’t take pot luck in considering the options available. Don’t select either the shortest or longest statements as the basis of making your selection. Don’t assume the answer to Qu.6 must be A as there hasn’t been an A answer for the previous five questions!
  • Unpreparedness. The merit of multiple choice questions is that they can span the whole spec and thus can leave the candidate exposed when chunks of knowledge they are supposed to know are not understood. It is thus easy to see how being unclear on the “fixture list” one can fall into the sin of having to guess the key simply because one is out of one’s depth. Don’t agonise too long on what are seen as testing questions given that each multiple choice question carries equal weight.

2. Falling real wages in the UK by David Blanchflower, Bruce V. Rauner Professor of Economics, Dartmouth College and Stephen Machin, Professor of Economics, University College London; Research Director at the Centre for Economic Performance, LSE; CEPR Research Fellow

The pain of the UK’s Great Recession has been spread more evenly than previous downturns, with falling real wages across the distribution. This column asks why this happened, how it compares with the US experience, and what the prospects are for recovering lost wage gains.

There have been unprecedented falls in real wages in the UK since the start of the recession triggered by the financial crisis of 2008. This did not happen in previous economic downturns – median real wage growth slowed down or stalled, but it did not fall. Indeed, in past recessions, almost all workers in both the lowest and highest deciles of the wage distribution experienced growing real wages. It was the unemployed who experienced almost all the pain – they lost their jobs and much of their incomes, and many were unemployed for a long time.

But in the Great Recession and its aftermath, the economic hurt has been spread more evenly, with wages taking the strain this time. The real wages of the typical (median) worker have fallen by around 8–10% – or around 2% a year behind inflation – since 2008. Such falls have occurred across the wage distribution, generating falls in living standards for most people, with the exception of those at the very top.

Some groups have been particularly hard hit, notably the young. Those aged 25 to 29 have seen real wage falls on the order of 12%; for those aged 18 to 24, there have been falls of over 15% (Gregg et al. 2014).

The young have thus been faced with a double whammy.

  • First, they cannot find jobs – there are still close to a million under the age of 25 who are unemployed, a quarter of whom have been unemployed continuously for at least a year.
  • Second, even if young people can find a job, it tends to be low paid, and frequently has fewer hours than they would like, often involving part-time rather than full-time work (Bell and Blanchflower 2011).

Why has this happened, and what are the prospects for recovering the lost wage gains that workers experienced relative to previous recessions? Some commentators believe that significant real wage growth is coming, and that the prospects are good for a return to the real wage growth patterns seen before the downturn.

We are more pessimistic. We believe that unless the division of economic growth becomes more fairly shared to offset long-run trends towards greater inequality, and unless productivity can be boosted to generate wage gains for all workers, then poor real wage outcomes for typical workers may be here to stay, just as they are in the US. Realistically, it is hard to see the levels of real wages at the start of the recession being restored for quite some time.

Median real wage growth in the UK and the US

Figure 1 shows what has happened to real wage growth for the median full-time worker in the UK between 1988 and 2013, alongside – as if as a warning sign – the comparable experience of the median full-time US worker.

Figure 1. Real wage growth at the median (50th percentile), full-time weekly wages, UK and US, 1988–2013

Source: UK data from New Earnings Survey/Annual Survey of Hours and Earnings from Gregg et al. (2014); US numbers from Current Population Survey, Bureau of Labor Statistics.

The UK median worker did relatively well in terms of real wage growth from 1988 up to somewhere around the early or middle part of the 2000s; but from this point, real wage growth began to slow down and then, in the wake of the 2008 downturn, it fell very rapidly indeed, moving into negative territory. Over the same period, the typical US worker fared rather badly, with real wages remaining below their 1988 levels up to 2000. Aside from a period in the first half of the 2000s and in 2009-10, when some very modest real wage growth occurred, real wage growth at the median was very weak.

Indeed, in 2013, median real weekly earnings were about the same in the US as they were in 1979. This is probably of concern for the UK’s prospects since the US went through a number of labour market changes some time before similar shifts in the UK. These include greater ‘flexibility’ and a massive reduction in the extent of union bargaining over wages.

Downward revision of wage growth forecasts

Current policy debates about the role of falling real wages in generating falling living standards (for example, in discussions of the ‘squeezed middle’ and the ‘top 1%’) make the question as to whether the falls in real wages can be reversed an extremely important one. So what are the conditions in which real wages could start to grow again and quickly?

A widely held view is that when the economic recovery kicks in seriously, then real wage growth will return. But wage growth forecasts by the Office for Budget Responsibility (OBR) have been remarkably over-optimistic.

Table 1 presents OBR forecasts at six points in time for nominal average earnings growth and real earnings growth (average earnings minus the OBR’s forecast of the consumer price index, CPI). Over time, each forecast has been downgraded from the previous forecast, which then proves to be overly optimistic and is downgraded again at the next forecast. In the most recent forecast for December 2013, the OBR is expecting real wage growth of 0.3% for 2014, which is down from the figure of 2.4% estimated in the June 2010 Budget and even as late as March 2012.

Table 1. Office for Budget Responsibility (OBR) forecasts of average earnings growth

Nominal 2012 2013 2014 2015
Budget June 2010 2.3% 3.8% 4.4% 4.4%
November 2011 2.0% 3.1% 4.3% 4.5%
March 2012 2.6% 3.1% 4.3% 4.5%
December 2012 2.7% 2.2% 2.8% 3.7%
March 2013 2.1% 1.4% 2.7% 3.6%
December 2013 2.0% 1.5% 2.6% 3.3%
Real 2012 2013 2014 2015
Budget June 2010 0.4% 1.8% 2.4% 2.4%
November 2011 -0.7% 1.0% 2.3% 2.5%
March 2012 -0.2% 1.2% 2.4% 2.5%
December 2012 -0.1% -0.3% 0.6% 1.7%
March 2013 -0.7% -1.4% 0.3% 1.5%
December 2013 -0.8% -1.1% 0.3% 1.2%

Notes: Average earnings = wages and salaries/employment; real earnings calculated as average earnings divided by OBR’s forecast of CPI.

In its February 2014 Inflation Report, the Bank of England’s Monetary Policy Committee (MPC) made similarly over-optimistic forecasts for real wage growth: “In the central projection, four-quarter growth in real pay turns positive towards the end of 2014, as productivity growth picks up”. This is despite the fact that in the most recent earnings data for February 2014, real average weekly earnings continue to fall at a rate of 0.8% a year. So as ever, a rapid turnaround is expected in real wage growth – but if it hasn’t happened for years, why should it happen now?

The case for pessimism

We have some serious concerns with this relative optimism.

  • First of all, to date, during the start of the recovery, the productivity performance of the economy has been weak and it has not created room for wage rises, even though it has been good news for employment and unemployment.
  • Second, because unemployment has not risen by as much as in previous recessions, when and if it falls, there is less scope than in the past for it to boost wage growth through the usual wage curve mechanisms (that is, the reverse of the wage-depressing effects of unemployment in Blanchflower and Oswald 1994).
  • Third, and a feature that predated the recession, because of inequality increasing average earnings by more than median earnings, the wages of typical UK workers are no longer keeping up with productivity gains made in the economy.

Indeed, as Figure 2 shows, measures of total compensation growth track productivity quite well, but median wage growth has fallen behind since at least the early 2000s.

Figure 2. Labour productivity, annual compensation, mean and median wages, 1988–2012

Sources: Office for National Statistics; New Earnings Survey/Annual Survey of Hours and Earnings; Gregg et al. (2014).

Median wages seem to have become ‘decoupled’ from productivity growth because of rising inequality, which means that a growing share of the value from productivity growth is absorbed by pensions and higher salaries for top earners (Bell and Van Reenen 2014). This again is something that the US experienced earlier than the UK, and where real wage performance for the typical worker has remained poor for over 30 years.

For significant real wage growth to re-emerge, all of these problems would need to be tackled. Productivity would need a sharp increase of the kind experienced much earlier in the UK recessions of the early 1980s and early 1990s. There are few signs of this happening, and the problem has been magnified by the UK’s dismal investment rates.

Even if productivity were to rise rapidly, the tendency for longer-run inequality trends to cause an unequal division of wages from productivity gains to the top (like bankers’ bonuses) would need to be addressed. Until that happens or until policy starts to address these issues seriously, it seems that the prospects of significant, rather than modest, wage increases for typical workers are bleak.

The main drivers of wage pressure come from an intricate blend of ‘insider’ and ‘outsider’ forces – people who would like to work and are currently in or out of a job. There is some evidence that unemployment has started to fall (although it rose in the most recent release from the Office for National Statistics), so outsider pressures pushing down on pay may have weakened a little.

But it is quite clear that the economy is still well below full employment and there is a large amount of slack in the labour market. We see little evidence of widespread skill shortages, which would push up wages; and public-sector pay freezes with continuing redundancies continue to push down on workers’ bargaining power.

Firms have started to perform better, so their ability to raise pay levels may have increased slightly – but so far we see no evidence of any change in their willingness to pay. In line with our discussion of inequality, this does raise a key question – why, if nothing changes, wouldn’t they continue to keep any gains to themselves? It stretches credulity to believe that all of a sudden bosses will hand over pay increases to their workers when they have shown no inclination to do so for several years.
