There seems to be consensus among most politicians on both sides of the Atlantic that there needs to be a reduction in government deficits and debt as a proportion of GDP. But there is considerable debate as to how such reductions should be achieved.

Conservatives, Republicans and centre right parties in Europe, such as Greece’s Νεα Διμοκρατια (New Democracy) party, believe that there should be tough policies to reduce government expenditure and that the deficit should be reduced relatively quickly in order to retain the confidence of markets.

Politicians on the centre left, including Labour, many Democrats in the USA and centre-left parties in Europe, such as François Hollande’s Socialists, argue that the austerity policies pursued by centre-right governments have led to a decline in growth, which makes it harder to reduce the current deficit.

Then there is debate about what is happening to the structural deficit – the deficit that would remain at a zero output gap. Politicians on the centre right argue that their austerity policies are leading to a rapid reduction in the structural deficit. This, combined with the supply-side policies they claim they are implementing, will allow growth to be resumed more quickly and will increase the long-term growth rate (i.e. the growth in potential output).

Politicians on the centre left argue that deep cuts, by reducing short-term growth (even making it negative in some cases, such as the UK), are discouraging investment and construction. This in turn will lower the growth in potential output and make it harder to reduce the structural deficit.

The following podcast and articles consider these arguments – arguments that are often badly put by politicians, who often use ‘questionable’ economics to justify their party line.

Questions

  1. Distinguish between the structural and cyclical budget deficit.
  2. Explain the distinction between stocks and flows. Which of the following are stocks and which are flows: (a) public-sector deficit; (b) public-sector debt; (c) public-sector net cash requirement; (d) debt reduction; (e) a bank’s balance sheet?
  3. Under what circumstances will a reduction in the public-sector deficit lead to: (a) a reduction in the public-sector debt (total); (b) a reduction in the public-sector debt as a proportion of GDP?
  4. How would you decide what is the desirable level of the public-sector deficit: (a) in the short run; (b) in the long run?
  5. Explain and comment on the following statement from the Stephanie Flanders article: “What is clear is that America has been able to ‘cut its debt (sic) further and faster’ than Britain – but this has not been the result of any closet commitment to austerity. Quite the opposite.”

Cartels are formal collusive agreements between firms, typically to fix prices, restrict output or divide up markets. As in the case of monopoly, the lack of competition may harm consumers, who are likely to have to pay higher prices. This, as economic theory demonstrates, results in a reduction in overall welfare.

For this reason competition authorities throughout the world now impose substantial fines on firms found to be involved in collusive activities and participants also face the threat of substantial jail sentences.

One of the most famous cartels is the Organization of Petroleum Exporting Countries (OPEC). This is an agreement between 12 countries to limit their production of oil. The OPEC cartel has been in place for over 50 years. Arguably, the intergovernmental nature of the cartel and political ramifications of intervening have meant that OPEC has been able to operate free from prosecution for so long.

However, very interestingly Freedom Watch, a US public interest group founded by a former US Department of Justice lawyer, has this week filed a lawsuit against OPEC for violation of competition laws. Quoted in the above press release, Larry Klayman, the founder of Freedom Watch, says that:

These artificially-inflated crude oil prices fall hard on the backs of Americans, many of whom cannot afford to buy gasoline during these severely depressed economic times.

Furthermore, how some of the members use the profits gained from the cartel is also called into question. He also goes on to suggest that the lack of intervention from US government agencies may be because the leaders of both political parties:

… line their pockets from big oil interests and are just sitting back and not doing anything.

This is not the first time that Freedom Watch has served a lawsuit on OPEC. In 2008, at an OPEC meeting in Florida:

In a bold move in front of members of the news media, Freedom Watch Chairman and Chief Legal Counsel Larry Klayman literally jumped out from behind a line of TV cameras and microphones on Friday, October 24, to serve a complaint on an OPEC oil minister.

That complaint was unsuccessful.

It will be fascinating to see the outcome of this latest case and, if successful, the implications for OPEC – updates to appear on this blog in due course.

John Von Neumann was a mathematician and one of his many accolades was applying mathematics and his observations of traditional games to create a new discipline – Game Theory. This involves a mathematical approach to decision making whereby different strategies can be assessed. It a tool that not only can be used in Economics, but also can be applied to a broad range of areas and fields of study.

Just as I arrived at work, I was listening to Radio 4 and heard the introduction to the programme In our Time. This one in particular caught my attention because of the name mentioned – Von Neumann, and after arriving in my office I then listened to the discussions surrounding game theory.

The main link is to the discussion from BBC Radio 4, led by Melvyn Bragg, with guests: Ian Stewart, a Professor of Mathematics from the University of Warwick; Andrew Colman, a Professor of Psychology at the University of Leicester and Richard Bradley, a Professor of Philosophy from the LSE. I’ll keep it brief and simply say enjoy!

Weather has already been partly blamed for poor economic growth, in particular in December 2010 and January 2011. April 2012 is no different – the wettest April on record is said to have caused the worst performance in sales since March 2011.

Like-for-like sales fell by 3.3%, mainly through lower demand for clothes and shoes. Supermarkets saw an increased demand for warmer food items with the colder weather and demand for home products also increased, with analysts suggesting that people decided to re-decorate their houses rather than venture outside! This was further supported by sales of gardening equipment, which also fell. However, the weather is not always bad – in March, sales were higher than expected, with the unusually warm weather, but unfortunately for growth statistics, the boost in sales in March has been more than offset by the decline in sales in April. Furthermore, there are concerns that the March ‘heat-wave’ may have encouraged consumers to do their summer shopping already and hence summer sales may suffer.

The retail data for April 2012 must be considered carefully, as comparing this month’s sales with the same period last year will be very misleading. Last April, the UK was hit with the Royal Wedding, which did boost sales of many products – underlying sales growth was recorded at 5.2% for the month. However, whilst April sales for 2012 could hardly hope to compete with April sales for 2011, the downward trend is undoubtedly going to cause concern for the government. Helen Dickinson, Head of Retail at KPMG said:

“While May will certainly be brighter than April, the health of the retail sector continues on a downward trajectory.”

Whether or not sales do continue their downward trend depends on many factors, including government policy measures to boost growth and cut unemployment. However, one other variable that may influence the trend is the weather. Here’s hoping that the sun shines and people begin to spend!

Questions

  1. Use a demand and supply diagram to illustrate the effects of the weather on equilibrium price and output.
  2. What other factors besides the weather affect retail sales?
  3. What government policy measures could be implemented to try to boost the retail sector?
  4. From the information you are told are there any sectors that surprise you in terms of whether sales have risen or fallen? Explain your answer in each case.
  5. With sales in April falling, what is the implication for a firm’s profits? What steps might a firm take in a bid to boost sales?

Original post (24/4/12)
The result of the first round of the French presidential elections on 22 April make it likely that François Hollande will be the new president.

M. Hollande can be described as an austerity sceptic. In other words, he questions the wisdom of trying to meet the target agreed by eurozone countries of reducing public-sector deficits to no more than 3% of GDP.

If elected, M. Hollande promises to adopt a more Keynesian stance of stimulating demand in order to prevent a slide into recession. This would mean a reversal of cuts and a growth, at least temporarily, of the public-sector deficit.

Currently France’s deficit is much higher than the 3% target. In 2010 it was 7.1%; in 2011 it had fallen somewhat to 5.2%. But it is set to rise in 2012, thanks to the slowing economy in France and most of the rest of Europe.

And it is not just in France that ‘austerity sceptics’ are on the ascendant. In the Netherlands the centre right government of Mark Rutte fell. He was unable to get his coalition partners to agree to sufficient cuts to achieve the 3% target. And yet, the Netherland’s deficit is considerably lower than most eurozone countries’. In 2012 it is projected to be just 4.6% of GDP.

So if doubts about the 3% target could lead to a change in policy in the Netherlands and France, what hope is there that the targets could be adhered to by countries with much larger deficits and where the pain of the cuts is already causing political turmoil?

The growth in austerity scepticism has spooked the markets. The day following M. Hollande’s first round victory and the fall of Mark Rutte’s government, stock markets around Europe plummeted and bond prices rose. The higher bond prices will make it even harder for governments to refinance maturing government debt. Take the case of France. As Robert Peston remarks in his article below:

According to IMF figures, 59% of France’s government debt is held overseas – which means that well over half of all lending to the French state is not motivated by sentimentality or patriotism in any way.

To put that figure into context, just 24.8% of UK general government debt is provided by foreigners.

Perhaps more relevantly, the French government has to borrow a colossal sum equivalent to 18.2% of GDP this year and 19.5% next year to finance debt that is maturing and the current deficit.

So what are the implications of the rise in austerity scepticism? Will it make deficits harder to finance? Will a collapse of confidence push the eurozone into a deep recession. Might the eurozone break apart? Or will a dose of Keynesian policies turn the tide and allow growth to resume, making it easier to service government debts? The following articles explore the issues?

Update (7/5/12)
François Hollande was indeed elected president on 6 May. The question now is to what extent he will be able to enact measures to simulate the economy. In his campaign he had talked about renegotiating the European treaty on budget discipline. Angela Merkel, responding to M. Hollande’s victory, said that the European fiscal treaty had been agreed and could not be renegotiated. Nevertheless, she said she was happy to consider new growth strategies that did not involve increased budget deficits.
