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...

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 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...

This document forms a record of a workshop held on 16 January 2006, aimed at examining the mechanisms underlying cross-country convergence of per capita GDP, to what extent they operate in practice, and the implications for policies, including those requiring plausible long-term projections of...

Climate change is expected to have significant implications for the world economy and, more broadly, for many areas of human activity. The purpose of this review is twofold. First, it is to summarise current estimates of the impacts of climate change and to explain how these estimates are built...

There are local air pollution benefits from pursuing greenhouse gases emissions mitigation policies, which lower the net costs of emission reductions and thereby may strengthen the incentives to participate in a global climate change mitigation agreement. The main purpose of this paper is to...

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...

The crisis that originated in mid-2007 in the United States and deepened in September 2008 is the largest peace-time disruption of financial markets since the Great Depression. It was triggered by a number of factors, namely the large amount of lending to subprime borrowers, the expansion of...
