Examiner's comment
Question 6 (g) This was a highly accessible question considering the methods that could be used to reduce the market failure associated with plastic waste. There are numerous possibilities that candidates could explore, and the vast majority talked about subsidies, taxation or minimum prices being introduced. This essay requires a clear exercise of critical analysis, and good candidates would be expected to have a developed a clear appreciation of the method of government intervention to correct the market failure. Sophisticated responses recognised that some forms of government intervention would be more effective than others. Good use of diagrams was showcased throughout the candidates’ responses, most commonly, an indirect tax diagram. To access evaluation marks candidates could explore the various strengths and weaknesses of each method proposed and use the prompts in the extracts to consider how effective the policy might be. Another line of development considered how some combination of policies might be necessary to effectively tackle the problem of environmental damage. The best responses would work by proposing realistic solutions to the problem of excess demand and then evaluating the most effective in the context of the real- world situation, in this case limiting the implications of too much consumption or production of plastic.
