Using official data from the Australian Bureau of Economic Statistics and a formal growth accounting framework, this paper shows that the rapid accumulation of information processing and communication technology (ICT) capital over the last two decades in Australia has played a significant role in explaining the impressive, structural acceleration of labor productivity. The following statistical data are also included: household income, expenditure and savings, labor market, fiscal indicators, credit aggregates, capital and financial account, external assets and liabilities, export by commodity group, and so on.

Market-based instruments like carbon taxes are potentially the most effective policies for reducing energy-related CO2 emissions. They do this by cutting the demand for fossil fuels and making it more attractive to use zero-carbon fuels like renewables.

Without action to control rising greenhouse gases (GHGs), scientists predict that climate change will continue over time, bringing higher temperatures, sea level rise, and the potential for abrupt changes in earth system processes, with likely negative impacts on agricultural yields, ecosystems, human health, and more.
An efficient forest carbon sequestration program could account for about a quarter of the desired global carbon dioxide (CO2) mitigation over this century (with most of the remaining 75 percent from reducing carbon emissions from fossil fuels). An estimated 42 percent of this carbon storage could be achieved via reduced deforestation, 31 percent from forest management, and 27 percent from afforestation, with about 70 percent of overall carbon sequestration occurring in tropical regions.
Low- and lower-middle-income countries contribute only about 12 percent of global carbon dioxide (CO2) emissions, though this share is increasing (and they account for a larger share of other greenhouse gases).
Developed economies have pledged to generate, from 2020, US$100 billion per year to help finance climate mitigation and adaptation in developing economies. This chapter discusses the potential role of fiscal instruments in raising this “climate finance.”
Although replacing regulatory emissions control policies with market-based instruments has produced significant cost savings, the predominant effect has been to reduce emissions. The savings and emission reductions have fallen somewhat short of their full potential, however, partly because actual designs have deviated from the most economically efficient designs (e.g., because programs are not fully comprehensive). Market-based policies have also promoted clean technology investments (although gains are not always as large as expected). Carbon leakage effects to date have been relatively modest.
The IMF Research Bulletin, a quarterly publication, selectively summarizes research and analytical work done by various departments at the IMF, and also provides a listing of research documents and other research-related activities, including conferences and seminars. The Bulletin is intended to serve as a summary guide to research done at the IMF on various topics, and to provide a better perspective on the analytical underpinnings of the IMF’s operational work.
