Considering the costs and risks of inaction, ambitious action to reduce greenhouse gas emissions is economically rational. However, success in abating world emissions will ultimately require a least-cost set of policy instruments that is applied as widely as possible across all emission sources...

This paper examines the cost of a range of national, regional and global mitigation policies and the corresponding incentives for countries to participate in ambitious international mitigation actions. The paper illustrates the scope for available instruments to strengthen these incentives and...

Spain uses its natural water resources intensively, mostly in agriculture, thanks to a highly developed dam infrastructure. The limits for extraction of natural resources have largely been reached and climate change is expected to continue lowering natural water endowments markedly in future...

Australia’s productivity growth has decelerated markedly around the turn of the century. Part of the decline is probably temporary, but raising multifactor productivity is key to ensure that living standards continue to grow strongly, especially if the currently strong terms of trade weaken...

Urbanisation in China has long been held back by various restrictions on land and internal migration but has taken off since the 1990s, as these impediments started to be gradually relaxed. People have moved in large numbers to richer cities, where productivity is higher and has increased...

The problems of Japanese agriculture – in particular low productivity and the prevalence of part-time farmers and small plots have been evident for the past 50 years. The high level and distortionary nature of agriculture support imposes burdens on consumers and taxpayers, undermines the...

This paper examines the heavily supported Swiss food and agriculture sector. It reviews some of the key features and trends in the sector and reveals its low relative labour productivity in international comparison. It describes the existing policy regime, including its various forms of support...

This paper uses WITCH, an integrated assessment model with a game-theoretic structure, to explore the prospects for, and the stability of broad coalitions to achieve ambitious climate change mitigation action. Only coalitions including all large emitting regions are found to be technically able...

This paper uses the WITCH model, a computable general equilibrium model with endogenous technological change, to explore the impact of various climate policies on energy technology choices and the costs of stabilising greenhouse gas concentrations. Current and future expected carbon prices...

This paper reviews alternative (national and international) climate change mitigation policy instruments and interactions across them. Carbon taxes, cap-and-trade schemes, standards and technology-support policies (R&D and clean technology deployment) in particular are assessed according to...
