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...

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...

Emissions trading systems (ETS) can play a major role in a cost-effective climate policy framework. Both direct linking of ETSs and indirect linking through a common crediting mechanism can reduce costs of action. We use a global recursive-dynamic computable general equilibrium model to assess...

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...
