When you look at the linked articles below, I’m sure many of you will be thinking that this is an odd choice for an economics blog! However, part of the economic relevance of ‘cyber-crime fighters’ relates to the relative skills of workers and the gap that exists between the most and least skilled workers in the UK.

Crime has always existed, but as technology has developed the types of crime committed have grown along with the complexity of them. For certain crimes, a very skilled individual is needed. With this emergence of technologically advanced crimes, those fighting crimes have also had to improve their skills and techniques. Thus crime-fighters have become more technologically advanced as well.

The problem is that the number of skilled workers able to deal with things like cyber crime has not kept pace with the demand for them and thus we have a skills gap. Usage of the Internet has continued to grow, creating more and more opportunities for cyber crime. However, the UK supply of IT and cyber-security professionals has not been able to keep pace. Therefore, we have a shortage of skilled labour in this area.

More investment into research and education is occurring, with the aim of addressing this shortage, but it is expected to take many years before supply catches up to demand. In particular, more investment is needed in the sciences and technology subjects at school to create the supply at university level. The NAO said that:

‘The current pipeline of graduates and practitioners are unable to meet demand.’

A second area of relevance to economics is the cost of cyber crime. The NAO estimated that the cost is somewhere between £18bn and £27bn per annum. However, on the other side, is there a case that crime actually benefits the macroeconomy by requiring government investment. As cyber crime has grown, so has the demand for cyber-crime fighters and this has created more jobs. With more jobs comes increased spending and the benefits of the multiplier. The following articles consider cyber crime and the impact it is having.

Questions

  1. Illustrate the demand for and supply of labour curves in the market for cyber crime fighters. How is the equilibrium wage determined?
  2. If there is increased investment in education, how would this affect the shape and position of the MRP curve and what impact would this have on your diagram?
  3. If there is a shortage of cyber crime fighters, what does that suggest about the position of the two curves? Illustrate this situation and explain why it is a problem.
  4. Which factors would be considered by NAO in estimating the costs of cyber crime?
  5. Explain why crime can pay.
  6. How does the macroeconomy benefit from increased crime? Illustrate this on a diagram.
  7. Does your answer to question 5 above suggest anything about the effectiveness of using GDP as a measure of welfare?
  8. How is the multiplier effect relevant?

According to the first estimate by the Office for National Statistics, the UK economy shrank by 0.3% in the final three months of 2012. This means that over the whole year growth was flat.

The biggest contributor to the fall in GDP in Q4 was the production industries, which include manufacturing. Output of the production sector fell by 1.8% in Q4. Construction sector output, by contrast, was estimated to have increased by 0.3%. Service sector output was flat. The chart below shows quarterly and annual growth in the UK from 2007 to 2012. (Click here for a PowerPoint.)

Latest estimates by the IMF are that the UK economy will grow by 1.0% in 2013 – well below the long-term growth in potential output (see also the last blog, High hopes in the Alps). But some forecasters are predicting that real GDP will continue to fall for at least one more quarter, which means that the economy would then be in a ‘triple-dip recession’.

Not surprisingly politicians have interpreted the statistics very differently, as have economists. The government, while recognising that the UK faces a ‘very difficult economic situation’, argues that now is not the time to change course and that by continuing with policies to reduce the deficit the economy will be placed on a firmer footing for sustained long-term growth

The opposition claims that the latest figures prove that the government’s policies are not working and that continuing attempts to bear down on the deficit are depressing aggregate demand and thereby keeping the economy depressed.

The following webcasts, podcasts and articles expand on these arguments. Try to be dispassionate in using economic analysis and evidence to assess the arguments.

  6. Find out what has happened to the UK’s public-sector deficit and debt over the past three years. Explain what has happened.

What lies ahead for economic growth in 2013 and beyond? And what policies should governments adopt to aid recovery? These are questions examined in four very different articles from The Guardian.

The first is by Nouriel Roubini, Professor of Economics at New York University’s Stern School of Business. He was one of the few economists to predict the collapse of the housing market in the USA in 2007 and the credit crunch and global recession that followed. He argues that continuing attempts by banks, governments and individuals to reduce debt and leverage will mean that the advanced economies will struggle to achieve an average rate of economic growth of 1%. He also identifies a number of other risks to the global economy.

In contrast to Roubini, who predicts that ‘stagnation and outright recession – exacerbated by front-loaded fiscal austerity, a strong euro and an ongoing credit crunch – remain Europe’s norm’, Christine Lagarde, head of the IMF and former French Finance Minister, predicts that the eurozone will return to growth. ‘It’s clearly the case’, she says, ‘that investors are returning to the eurozone, and resuming confidence in that market.’ Her views are echoed by world leaders meeting at the World Economic Forum in Davos, Switzerland, who are generally optimistic about prospects for economic recovery in the eurozone.

The third article, by Aditya Chakrabortty, economics leader writer for The Guardian, looks at the policies advocated at the end of World War II by the Polish economist, Michael Kalecki and argues that such policies are relevant today. Rather than responding to high deficits and debt by adopting tough fiscal austerity measures, governments should adopt expansionary fiscal policy, targeted at expanding infrastructure and increasing capacity in the economy. That would have an expansionary effect on both aggregate demand and aggregate supply. Sticking with austerity will result in continuing recession and the ‘the transfer of wealth and power into ever fewer hands.’

But while in the UK and the eurozone austerity policies are taking hold, the new government in Japan is adopting a sharply expansionary mix of fiscal and monetary policies – much as Kalecki would have advocated. The Bank of Japan will engage in large-scale quantitative easing, which will become an open-ended commitment in 2014, and is raising its inflation target from 1% to 2%. Meanwhile the Japanese government has decided to raise government spending on infrastructure and other government projects.

So – a range of analyses and policies for you to think about!

We know two things about economic growth in a developed economy like the UK: it is positive over the longer term, but highly volatile in the short term. We can refer to these two facts as the twin characteristics of growth. The volatility of growth sees occasional recessions, i.e. two or more consecutive quarters of declining output. Since 1973, the UK has experienced six recessions.

Here we consider in a little more detail the growth numbers for the UK from the latest Quarterly National Accounts, focusing on the depth and duration of these six recessions. How do they compare?

The latest figures on British economic growth show that the UK economy grew by 0.9 per cent in the third quarter of 2012. However, when compared with the third quarter of 2011, output was essentially unchanged. This means that the annual rate of growth was zero. Perhaps even more telling is that output (real GDP) in Q3 2012 was still 3.0 per cent below its Q1 2008 level.

The chart helps to put the recent output numbers into an historical context. It shows both the quarter-to-quarter changes in real GDP (right-hand axis) and the level of output as measured by GDP at constant 2009 prices (left-hand axis). It captures nicely the twin characteristics of growth. Since 1970, the average rate of growth each quarter has been 0.6 per cent. This is equivalent to an average rate of growth of 2.35 per cent per year. The chart also allows us to pin-point periods of recessions.

One way of comparing recessions is to compare their ‘2 Ds’: depth and duration. The table shows the number of quarters each of the six recessions since 1973 lasted. It also shows how much smaller the economy was by the end of each recession. In other words, it shows the depth of each recession as measured by the percentage reduction in output (real GDP).

British recessions

Duration (quarters) Depth (output lost, %)
1973Q3–74Q1 3 3.25
1975Q2–75Q3 2 1.76
1980Q1–81Q1 5 4.63
1990Q3–91Q3 5 2.93
2008Q2–09Q2 5 6.28
2011Q4–12Q2 3 0.90

We can see that three of the recessions lasted for five quarters. In the case of the recessions starting in 1975 and 2011 they occurred very shortly after a previous recession. Hence, we observe two so-called double-dip recessions.

The table reveals that the deepest recession by some distance was that in the late 2000s. As a result of this recession, UK output declined by 6.3 per cent. As the recent GDP numbers show, the UK has yet to recover the ‘lost output’ that followed the financial crisis.

Questions

  1. What is the difference between nominal and real GDP? Which of these helps to track changes in economic output?
  2. Looking at the chart above, summarise the key patterns in real GDP since the 1970s.
  3. What is a recession? What is a double-dip recession?
  4. Looking at the table, rank the recessions from 1973 by the amount of lost output.
  5. Can a recession occur if nominal GDP is actually rising? Explain your answer.
  6. What factors might result in economic growth being so variable?

If aggregate demand were to expand, would there be sufficient spare capacity to allow aggregate supply to expand to meet the additional demand? This is the question addressed by the podcast and article below.

If there is plenty of spare capacity, policies to increase aggregate demand could help to take up the slack and thereby achieve economic growth – at least as long as spare capacity remains. In other words, in the short run the aggregate supply curve may be horizontal or only gently upward sloping at the current point of intersection with the aggregate demand curve. This is illustrated by point a in the diagram. A rightward shift in the aggregate demand curve would cause a movement along the aggregate supply curve to a new higher level of real national income (Y).

If, however, there is little or no spare capacity, an increase in nominal aggregate demand is likely to be purely inflationary, or virtually so. This would the case at point b in the diagram. Real national income cannot expand beyond the full-capacity level, YFC. Under such circumstances, any attempt by the government to stimulate economic growth should focus on the supply side and attempt to shift the aggregate supply curve to the right. Examples of supply-side policy include incentives to encourage research and development, incentives for the private sector to invest in new capacity and direct public investment in infrastructure.

Unemployment is not just caused by a lack of aggregate demand relative to aggregate supply. It may be the result of a mismatching of labour supply with the demand for labour. People may have the wrong qualifications or not be where the jobs are. Unemployment may co-exist with quite high levels of vacancies. There may be vacancies for highly qualified scientists, technicians or craftspeople and unemployment of people with low skills or skills no longer in high demand. The same may apply to capital equipment. There may be a shortage of high-tech equipment or equipment to produce goods in high demand and redundant older equipment or equipment in areas of declining demand.

Part of a comprehensive set of policies to tackle unemployment and achieve economic growth would be to focus on the whole balance of the economy and the matching of the demand and supply of inputs.
