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

  1. For what reasons does the free market fail to achieve an optimum level of consumption of junk foods, alcohol and cigarettes?
  2. How would you determine the socially optimum level of consumption of such products?
  3. 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?
  4. What determines the incidence of taxes on unhealthy products?
  5. 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.
  6. To what extent do the objectives of social efficiency and equity conflict when designing appropriate policies to discourage unhealthy consumption?

The economist Joseph Stiglitz won the Nobel Prize for Economics in 2001. Along with George Akerlof and Michael Spence, he worked out a theory of information asymmetry: a situation where both parties in a transaction have different levels of information. Could this theory have some relevance as an explanation of the current financial crisis?

Have you ever had a drink or packet of peanuts from a hotel minibar and then regretted being tempted when you saw the price on checkout? If things like minibars and internet access are so over-priced in hotels, then how can they get away with it? Why do people pay these amounts and what can economics tell us about this pricing behaviour?
