Somali pirates have been much in the news recently with their high profile captures of oil tankers and other ships. The impact on shipping in the area is clear and this has disrupted trade in the region, but an unforeseen impact has been on the total worldwide catch of tuna. The Indian Ocean is one of the richest sources of tuna in the world and the pirate activity has led to a fall of around 30% in the total tuna catch.

Somali piracy ‘reduces tuna haul’ BBC News Online (22/1/09)

Questions

  1. Using diagrams as appropriate, show the impact of Somali pirate activity on the market for tuna.
  2. Suggest likely values for the price elasticity of demand and supply of tuna. Analyse the extent to which these values are likely to affect the price rise in the market for tuna.
  3. What substitutes are available for tuna? Assess the extent to which the availability of substitutes will affect the rise in the price of tuna.

One of the industries always hard hit by any economic downturn is the building and construction industry. The three articles below look at different aspects of the construction downturn. The building industry in Spain (article 1) has been particularly hard hit, perhaps because of the previous scale of the boom. When there is a recession, different industries are always hit in different ways, depending on the nature of the demand they face. Construction and building can be very badly affected as much of the expenditure on them is ‘investment’ expenditure and this will often be delayed in times of economic downturn.

Questions

  2. Explain the accelerator theory.
  3. Discuss the extent to which the accelerator theory might help to explain the current state of the construction industry in the UK and Spain.

While deflation was quite common right up to World War II, it has not been seen in the UK since 1947. The podcast considers whether it might return and looks at the impact of deflation on economic activity. There is a short case study on the deflationary years suffered by Japan between 1997 and 2006 and a consideration of policies that might be appropriate to overcome defaltionary pressures.

Peak oil is an important concept for the oil market. Peak oil is the moment in time at which the maximum extraction rate of oil is reached. From this moment on, production will decline. Basic economics tells us that the oil price will tend to rise from then on (unless demand were to fall faster), but the complexities of the demand and supply for oil dictate that there will not be a simple inverse relationship between the supply of oil and the price. In the articles below George Monbiot interviews Faith Birol, the Chief Economist of the International Energy Agency and the Asia Times article looks at the extent to which world economies rely on oil for energy and other needs. Oil prices may be low at the moment and the market may be awash with excess oil and not enough demand for it, but this is a short term phenomenon; there is little doubt about the long-term direction of the price.

Questions

  1. Write a short paragraph explaining what is meant by peak oil.
  2. Using diagrams as appropriate, explain the changes that took place in the oil price in the last six months of 2008.
  3. Analyse the likely impact on the UK economy of arriving at peak oil output in (a) the short term and (b) the long term.
  4. Discuss when peak oil is likely to arrive.

Governments and central banks around the world are trying hard to minimise the impact of the economic downturn on their economies. One means of doing this is to cut interest rates. The aim is to boost aggregate demand by giving people more disposable income and making borrowing and investment cheaper. But how responsive will people be to the interest rate cuts? The articles and podcasts below look at the issues.
