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?
In times of recession, some companies can do well, even in industries where there are supply problems. One such example is Pacific Andes, a Hong Kong based frozen seafood firm. Many fishing companies have found times tough in an era of dwindling fish stocks and fishing quotas imposed by governments anxious to preserve stocks. The following article looks at Pacific Andes and how it has managed to prosper despite supply challenges and the global recession.

Details of overfishing in the UK can be found at: EyeOverFishing
The site provides a “map of the UK fisheries system, the problems with it, and solutions that are possible today”.
Questions
- To what extent can the concept of income elasticity of demand be used to help explain why Pacific Andes has managed to prosper during the recession?
- What specific business strategies has Pacific Andes adopted and why?
- Why, if overfishing is to the detriment of the fishing indsutry, do fishing fleets still overfish many parts of the oceans? Explain why this is an example of the ‘tragedy of the commons’.
- What would you understand by an ‘optimum level of fishing’ for a particular type of fish in a particular part of the oceans? Explore whether the concept of a ‘social optimum’ in this context is the same as an ‘environmental optimum’?
2008 may yet come to be seen as the year that marks the death of the single-use plastic bag. Many countries around the world, including China, have banned their use and February 2008 has seen Marks and Spencer announcing a 5p charge per plastic bag in an attempt to reduce their usage. Even government departments have faced criticism over their use as promotional tools. For more details on plastic bag bans and policies relating to limiting their usage, see our 2007/8 podcast on The economics of plastic bags elsewhere on the site.

In the article below, Ashley Seager from the Guardian argues that the government is doing little to encourage the take-up and adoption of alternative forms of energy generation for households. Indeed he argues hat the situation has got worse and not better in recent months with changes in the system. Only 270 houses were helped with the fitting of photovoltaic systems last year. In Germany the equivalent figure was 130,000.

A report from Cycling England has suggested that a £70m investment in cycling each year could save the government £520m per year. The savings result from the positive benefits of increased cycling – lower carbon dioxide emissions and lower NHS costs as we become healthier. But, do the numbers add up?
