By the government introducing an indirect tax on non-degradable chewing gum, it hopes that consumers will become aware of the now more expensive non-degradable gum and turn to the cheaper more environmentally friendly, biodegradable gum. Therefore, less permanent gum will be dropped onto the streets and subsequently costs on local councils will be reduced.
However, by implementing these taxes on chewing gum, the government may become unpopular within the public from the increased price and therefore will become less likely to implement taxes and policies to better improve the environment and public areas, in the future.
It can also be argued that this is not the best-suited option to deal with the market failure. Alternatively, the government could implement fines to those caught littering gum on the streets. This would no doubt make consumers think-twice before littering and become more aware, however it would cost the government money to at first implement and then supervise these regulations, and so taxation is most likely a better option.
Similarly, the government could altogether enforce a ban on chewing gum. This is the most effective way of dealing with the littering issue, however it has drawbacks, which outweigh the positive benefits. Firstly, a ban of that proportion on a good, which is extremely popular, would cause public resentment and would cost the government huge amounts of money to enforce, which could be better spent in other public services such as the NHS. Secondly, the removing the gum industry entirely would have a negative effect on the economy; forcing firms to close and therefore leave unemployed workers. Furthermore, the government would lose a significant proportion of its tax revenue.
Additionally, when predicting if these taxes will have the governments desired effect and saves local councils money, it is questionable that due to the price elasticity of demand for chewing gum being highly inelastic, the taxes (increased price) may be ineffective. Price elasticity of demand is the responsiveness of the quantity demanded to a change in price for a product. If consumers didn’t care about the change in price, due to it still being a cheap good, despite the relative change in price being substantial, then the demand for gum would change proportionately less than the price changes and hence nullify the effects of government taxes.
Overall, there is no perfect solution to this market failure. However, an indirect tax is most likely the most sensible solution. Although it cannot be proven how the market will react in terms of elasticity of demand, it will at the minimum make the cheaper biodegradable option look more attractive. It is also a cheapest solution to implement.
