Are policies designed to avert climate change (Climate Change Policies, or CCPs) politically costly? Using data on governmental popular support and the OECD's Environmental Stringency Index, we find that CCPs are not necessarily politically costly: policy design matters. First, only market-based...

Macroeconomic costs of conflict are generally very large, with GDP per capita about 28 percent lower ten years after conflict onset. This is overwhelmingly driven by private consumption, which falls by 25 percent ten years after conflict onset. Conflict is also associated with dramatic declines...

The Netherlands has ambitious greenhouse gas emission reduction targets for the future - to cut them by 49 percent below 1990 levels by 2030 and 95 percent by 2050. These targets and the likely new EU-wide targets under the recent EU Green Deal entail a rapid acceleration in decarbonization....

The United States has pledged to become carbon neutral by 2050, meet sectoral objectives (e.g., for carbon free power, electric vehicles) and encourage greater mitigation among large emitting countries and of international transportation emissions. Fiscal policies at the national, sectoral, and...

In short, yes. I use a multi-region integrated assessment model with fuel-specific endogenous technical change to examine the impact of Europe and China reducing emissions to zero by mid-century. Without international technological diffusion this is insufficient to avoid catastrophic climate...

Finland has pledged to cut net greenhouse gas emissions to zero by 2035 and has sectoral targets for deploying electric vehicles, phasing out coal generation, and oil-based space heating. Fiscal policies at the national and sectoral level could play a critical role in achieving these objectives....

Climate change is a major threat to the sustainability and inclusiveness of our societies, and to the planet's habitability. A just transition to a low-carbon economy is the only viable way forward. This paper reviews the climate change challenge. It stresses the criticality of systems changes...
