The World's nations have yet to reach a truly effective treaty to control the emission of greenhouse gases.  The importance of compatibility with private incentives of individual countries has been acknowledged (at least by game theorists) in designing climate policies for the post-Kyoto...

I develop a dynamic model of private provision of public bads allowing investments in technologies. The analysis is tractable and the MPE unique. The framework is used to derive optimal incomplete contracts in a dynamic setting. While the noncooperative equilibrium is very inefficient,...

I develop a dynamic model of costly private provision of public goods where agents can also invest in cost-reducing technologies. Despite the n+1 stocks in the model, the analysis is tractable and the (Markov perfect) equilibrium unique. The frame-work is used to derive optimal incomplete...

Many countries have pledged targets or actions to reduce greenhouse gas emissions; these have been listed in the Appendices to the Copenhagen Accord and, at the time of writing, are being transferred to the UNFCCC Cancún Agreements. This analysis examines the costs and effectiveness of these...

That climate policies are costly is evident and therefore often creates major fears. But the alternative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are; moreover, they are substitutes. This brings climate policies naturally in the realm...

We consider how one party can induce another party to join an international emission compact given private information. Due to multilateral externalities the principal uses her own emissions besides subsidies to incentivize the agent. This leads to a number of non-standard features: Optimal...

This paper argues that it is countries' historical experience with democracy, the democratic capital stock, rather than current levels of democracy that determines current climate change policies. Empirical evidence using data starting as far back as year 1800 for 87 countries, which together...

In order to overcome the underprovision of global public goods various different policy approaches have been proposed. In the climate policy arena, international transfers are frequently seen as an effective means to raise the provision of the global public good ‘climate change mitigation’....

It is well established that adaptation and technological investment in each case may serve as a commitment device in international climate politics. This paper for the first time analyzes the combined impact of these two strategic variables on global mitigation within a noncooperative framework...

This paper explores implications of climate change for fiscal policy by assessing the impact of large scale extreme weather events on changes in public budgets. We apply alternative measures for large scale extreme weather events and conclude that the budgetary impact of such events ranges...
