Denmark has a highly ambitious goal of reducing greenhouse gas emissions 70 percent below 1990 levels by 2030. While there is general agreement that carbon pricing should be the centerpiece of Denmark’s mitigation strategy, pricing needs to be effective, address equity and leakage concerns,...

Consider a dynamic model with two countries or coalitions that consume and trade fossil fuel. A non-abating country owns the entire fuel stock and is not concerned about climate change, represented by a ceiling on the carbon dioxide concentration. The government of the other country implements...

It is tricky to design local regulations on global externalities, especially so if firms are mobile. We show that when costs and outside options are firms' private information, the threat of firm relocation leads to local regulations that are stricter, not looser. This result is general and...

Integrated assessment models (IAMs) provide key inputs to decision-makers on economically efficient climate policies, and technical change is one of the key assumptions in any IAM that estimates mitigation costs. We conduct a systematic survey of how technical change is currently represented in...

Many poor countries are ill-adapted to the current leave alone a changing future climate, because they lack the necessary financial means to invest in efficient and cost-effective safeguarding measures. International endeavours to fund institutions, such as the Green Climate Fund, to provide...

Hurricanes are among the costliest natural disasters in the world, with a significant portion of their impact linked to the accuracy of their forecasts. In this paper, we estimate the economic impacts of the official hurricane forecasts in the US and develop a new approach for measuring the...

Climate challenge can be modelled as a multiplayer prisoner's dilemma where any ecological action - i.e., purchasing an electric car or adopting sustainable life styles - is a costly action in terms of economic resources, time, and effort for individuals. According to the well-known embedded...

"Moral hazard" links geoengineering to mitigation via the fear that either solar geoengineering (solar radiation management, SRM) or carbon dioxide removal (CDR) might crowd out the desire to cut emissions. We test moral hazard versus its inverse in the first large-scale, revealed-preference...

This paper provides quantitative evidence on the geography of regional readiness to tackle climate change using data from France, Germany, Italy, Poland, and Spain. Following Cappellano et al. (2022), we estimate a composite indicator that reports the situation of regions in these countries...
