Discussions in Australia about carbon pricing policies, particularly the effectiveness of measures to address environmental externalities related to carbon emissions, are prevalent. One significant aspect is the Emissions Reduction Fund (ERF) and its effectiveness in curbing carbon emissions and combating climate change. The attached reading "the article 2" provides a review of the ERF by the Climate Change Authority as of October 2020. By reading this review, please answer the following questions:
i) Identify and explain how the ERF operates within the context of market failures and externalities related to environmental concerns, particularly in reducing emissions and maintaining environmental integrity.
(20 Points)
ii) Evaluate the effectiveness of the ERF in achieving its stated objectives and addressing market failures associated with carbon emissions.
(20 Points)
iii) Consider the role of government policy and the voluntary market in incentivizing low-cost abatement actions and suggest potential improvements or alternative strategies to enhance the ERF's efficacy in reducing emissions within Australia.
