Could someone please:help me with this assignment topic please?

Topic:

In many countries, including Australia, obesity is a problem, and some people in the health industry have argued that a tax on sugar-sweetened beverages (SSBs) is required.

Explain, with the use of an appropriate economic model, the type of externality that a tax on sugar-sweetened beverages (SSBs) would aim to address. Using economic terms and analysis, discuss the possible advantages and disadvantages of this type of tax, and whether or not it is likely to be effective at reducing health problems associated with obesity.

1. Policy evaluation

Outline the types of policies that could be used to address a negative consumption externality. (market based vs regulation)

Include a theoretical diagram/graph to demonstrate how this specific policy - the tax on SSBs - (in theory) addresses the market failure associated with a negative consumption externality.

Evaluate the effectiveness - advantages and disadvantages - of proposed a tax on SSBs with evidence to support assertions. (regressive, inelastic demand curve, tax and whats included for the sugar sweetened bevrages,artificial)

When evaluating the policy, consider issues such as the ease of implementation (politically), cost of implementing the policy, effectiveness (will it work), equity concerns, other issues that impact the effectiveness of the policy. Are there other alternative policies that you think would be better? If so, include theory and evidence.

Evidence from similar policies in other countries can be used.

Brief overall evaluation.
