The US Institute of Medicine of the National Academies has recently published a 92-page on report on childhood obesity and the use of taxes on junk foods to tackle the problem. In the report, titled Local Government Actions to Prevent Childhood Obesity, “a panel of experts suggested such taxes could play an important role in helping children make healthier eating choices”.
Meanwhile, in Australia, the Federal Government’s preventive health taskforce argued, amongst other things, that “junk food advertising should be phased out, the cost of cigarettes should be more than $20 a packet, and soft drinks and cask wine should be hit with higher taxes”.
So how effective are higher taxes in achieving a reduction in ill health associated with eating, drinking and smoking? If adopted, what is the socially optimum design and rates of such taxes? What other complementary policies could be adopted? The following articles consider the issues.

Questions
- For what reasons does the free market fail to achieve an optimum level of consumption of junk foods, alcohol and cigarettes?
- How would you determine the socially optimum level of consumption of such products?
- How are the price, income and cross-price elasticities of demand, and the price elasticity of supply, relevant to assessing the effectiveness of taxes for reducing the consumption of unhealthy products?
- What determines the incidence of taxes on unhealthy products?
- What other policies would you advocate to tackle the problems associated with consuming unhealthy products? How would they affect the price elasticity of demand for such products.
- To what extent do the objectives of social efficiency and equity conflict when designing appropriate policies to discourage unhealthy consumption?
Tea prices have soared in recent months. Explanations can be found on both the demand and supply side. But while this might be bad news for tea drinkers, the news is more mixed for tea growers. So just what are the causes and consequences of the price rises? The following linked articles look at the issues.

Many primary commodity prices have fallen during the recession, but have recovered somewhat as the recession has bottomed out and hopes of a recovery have grown. So what will happen to commodity prices over the next few months and beyond, and what will determine the size of the price changes? The following linked articles look at these questions.

Questions
- Why have oil prices fluctuated so much over the past year?
- What is likely to happen to the price of oil over the next few months and why?
- Why is the price of oil likely to rise faster than the rate of inflation over the long term?
- How are the price, income and cross elasticities of demand and the price elasticity of supply relevant to explaining the likely long-term trend in oil prices?
- If the price of crude oil goes up by x per cent, is the price of petrol at the pump likely to go up by x per cent or by more or less than x per cent? Explain your answer.
According to both the Lloyds Banking Group’s Halifax price index and the Nationwide Building Society, the annual rate of decline in house prices is reducing and the three-monthly figures now show a small increase in house prices. So does this mean that the housing market is now recovering?
The Centre for Economics and Business Research (CEBR) is forecasting a rise of 2 per cent in house prices between the end of 2009 and the end of 2010. Other forecasters are predicting higher price increases. Part of the reason lies on the demand side, but part also lies on the supply side. The following linked articles explore these determinants of demand and supply.
