Skin cancer is on the increase in the UK. Calls are thus being made by both retailers and cancer charities for a cut in VAT on sun cream.

At present the VAT rate on sun cream in the UK is the standard rate of 17.5%, which is due to increase to 20% in January 2011. But would cutting the rate to 5%, as is being proposed, be effective in cutting skin cancer rates? What information would you, as an economist, need to assess this claim?

Questions

  1. What would determine the incidence of a cut in VAT on sun creams between consumers and retailiers?
  2. If there were a 50:50 incidence of a VAT cut between consumers and retailers and the VAT was cut from 17.5% to 5%, what percentage fall in the retail price would you expect?
  3. Assume that the price elasticity of demand for sun cream is –1 and price elasticity of supply is +1, how much would sales of sun cream rise if the VAT rate fell from 17.5% to 5%? Are these realistic values for the price elasticity of demand and supply?
  4. Under what circumstances may promoting the use of sun creams encourage the development of skin cancer?
  5. Are people being rational if they choose to expose themselves to the sun for long periods in order to receive a ‘fashionable’ tan? How are time preference rates (personal discount rates) relevant here?
  6. What market failures are involved in the tanning industry? If the use of sunbeds contributes towards skin cancer, should they be banned?

What’s going to happen to stock market prices? If we knew that, we could be very rich! Nevertheless, financial analysts constantly try to predict the movements of shares in order to decide when to buy and when to sell. One thing they do is to look at charts of price movements and look for patterns. These ‘chartists’, as they are sometimes called, refer to something known as the ‘death cross’ or ‘dark cross’.

So what is the death cross? Imagine a chart of the movements of share prices, such as the FTSE 100 in the UK or the Dow Jones Industrial Average and S&P 500 in the USA. These movements can be shown as a moving average. In other words, for each day you plot the average of the past so many days. Typically, 200-day (sometimes 100-day) and 50-day moving averages are plotted. The 200-day (or 100-day) is taken as the long-term moving average and the 50-day as the short-term moving average. In a falling market, if the short-term moving average crosses below the long-term moving average, this is called the ‘death cross‘ as it signifies growing downward pressure in the market. The fall in the long-term average in these circumstances will indeed lag behind the fall in the short-term moving average.

Markets around the world are experiencing the death cross. So should be be worried? Or is this like looking for patterns in tea leaves, or the stars, and using them to make bogus predictions? So: science or mumbo jumbo?

First the science: the death cross indicates a fall in confidence. And at present, there is much for investors to worry about. Burgeoning debts, austerity measures and fears of a double-dip recession are spooking markets.

Now the mumbo jumbo. Just because markets are falling at the moment, this does not prove that they will go on falling. Markets are often spooked, only to recover when ‘sanity’ returns. People may soon start to believe that a second credit crunch will not return, given all the regulatory and support measures put in place, the huge amount of liquidity waiting to be invested and the support packages from the ECB and IMF for Greece and, potentially, for other eurozone countries having difficulties servicing their debts. In other words, patterns may repeat themselves, but not necessarily. It depends on circumstances.

Questions

  1. Explain what is meant by the death cross and use a diagram to illustrate it. What is menat by the golden cross. Again, use a diagram to illustrate it.
  2. Under what circumstances would speculation against stock market price movements be (a) stabilising and (b) destabilising?
  3. What is the implication for stock market prices of a ‘wall of money’?
  4. How much faith should be put in chartist explanations of stock market prices? Do criticisms of chartism apply to all time-series analysis that is used for forecasting?
  5. Look back at newspaper articles from a year ago and see what they were predicting about stock market prices. Have their preductions been borne out? If so, why? If not, why not?

A large deficit which needs cutting and this needs decisive action. This was the gist of the message from George Osborne, and generally from the Coalition government. Although there is nothing confirmed in terms of what to expect, it is thought that there will be a proposal to ease National Insurance for new businesses. He said:

“And so we’ve got to deal with that [the country in Europe with the largest budget deficit of any major economy]. In that sense it’s an unavoidable Budget, but what I’m determined to do is to make sure that the measures are tough but they’re also fair and that we’re all in this together and that, as a country, we take the steps necessary to actually provide the prosperity for the future.”

We already know that there are plans in place to increase capital gains tax from 18% to nearer 40%, but beyond that, little is known. There are concerns that this policy may actually cost the government more in tax revenue than it will raise. Other policies we might expect include a rise in VAT, and a slashed spending budget for pensions. These spending cuts and tax rises will help Osborne to eliminate the structural deficit in current spending by 2015, when the Coalitions’ current term comes to an end. The success of the Coalition’s policies and their ability to reduce the deficit without causing the economy to fall back into recession will be crucial in determining whether the current term is the only term.

Questions

  1. To what extent is it necessary to cut the budget deficit now and not delay it until the recovery is more secured?
  2. How will easing National Insurance for small businesses affect the economy?
  3. If capital gains tax goes up, why is there concern that this could actually cost the government? How is this possible?
  4. The Lib Dems will oppose any increase in VAT, as they argue it is a regressive tax. What does this mean?
  5. How will the report by the Office for Budget Responsibility have affected Osborne’s emergency budget?

The annual Agricultural Outlook for the next ten years has just been published jointly by the OECD and the UN Food and Agriculture Organization (FAO). Click here and here for audio presentations of the report by the FAO’s Jacques Diouf and the OECD’s Angel Gurría.

The report argues that world recovery will raise agricultural prices. This will be partly the direct result of higher demand and partly the result of higher prices of agricultural inputs, such as fertilisers and fuel. But prices will not rise back to the peak levels of 2007/8. These higher prices, however, would have a positive effect on world food output, especially in the BRICs (Brazil, Russia, India and China). This, in turn, would limit the price rises.

So is this good news for food producers and consumers? The following articles look at the issues

Throughout 2009/10, a new millionaire was created in Brazil every 10 minutes – not bad for a developing country! Despite the global recession, Brazil has managed growth of almost 5% and is set to overtake both the UK and France to become the world’s 5th largest economy. Brazil will hold the next World Cup and the Olympic games after London, bringing it further recognition as a global power. It has the third largest aircraft manufacturing industry in the world and is even doing its bit to tackle climate change, with 50% of its cars running on bio-fuels. It exports more meat than any other country and is looking to become an energy power. With falling unemployment, a buoyant economy, growing confidence, fantastic beaches and 6 millionaires created every hour, Brazil looks like the perfect place to live.

However, that is just one side of the story. Brazil is still a country with deep poverty – approximately 60 million people. The slums, or favelas, are home to 1 million people in Rio alone, where unemployment is high and drug wars common. There has been a concerted effort to reduce the drug trafficking business, but this has only created more unemployment. There is little sanitation, poor electricity and minimal chance of escape. Neighbourhoods need rebuilding, and despite high growth and arguably the most popular president in the world (Lula da Silva), there are calls for political, social, taxation and labour market reforms. This cycle of poverty and the equality gap needs addressing before the Brazilian economy can really be considered a global power.
