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...

Developments over the past few years have shown that reforms to address climate change are no less difficult to implement than reforms in other areas, even if the objective of limiting global warming is broadly accepted. In the case of global public goods such as the climate, the political...

Despite its apparent advantages, devolution of fiscal responsibilities has not proceeded evenly over the past two decades. Decentralisation can strengthen the democratic process, allow governments to tailor the supply of public goods to local preferences and introduce some competition across...

This paper sheds light on inter-regional migration, housing and the role of policies, drawing on a new comparative cross-country approach. The results show that OECD countries exhibit stark variation in both levels and trends in inter-regional migration, which is found to be highly responsive to...

Despite its apparent advantages, devolution of fiscal responsibilities has not proceeded evenly over the past two decades. Decentralisation can strengthen the democratic process, allow governments to tailor the supply of public goods to local preferences and introduce some competition across...

Regional inequality is low in Sweden compared to most other OECD countries, but has been rising over the past decades, fuelling discontent in parts of the country, whose inhabitants feel left behind. The younger population is increasingly concentrated in the largest cities, which also enjoy the...

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...

This paper develops and applies a simple “conditional growth” framework to make long-term GDP projections for the world economy, taking as a starting point recent empirical evidence about the importance of total factor productivity and human capital in explaining current cross-country...
