This article explores the links between climate neutrality and sustainability in the context of international trade. For that, it tackles seven main concerns: 1) what do industry leaders now need from policymakers to make them the frontrunners in the global transition to climate neutrality? 2)...

Many international policy problems, including climate change, have been characterized as global public goods. We adopt this theoretical framework to identify the baseline determinants of individual opinion about climate policy. The model implies that support for climate action will be increasing...

The extent of future climate change is a policy choice. Using an integrated climate-economy assessment model, we estimate climate policy curves (CPCs) that link the price of carbon dioxide (CO2) to subsequent global temperatures. The resulting downward sloping CPCs quantify the inverse...

This paper compares the Kyoto Protocol and the Paris Agreement in the dynamic game of Battaglini and Harstad (2016). The asymmetric Nash solution of this game reflects the Paris Agreement, whereas the symmetric Nash solution reflects the Kyoto Protocol. In a large set of economies, the Kyoto...

Major carbon-pricing systems in Europe and North America involve multiple countries or states. Individual jurisdictions often pursue additional initiatives---such as unilateral carbon price floors, legislation to phase out coal, aviation taxes or support programs for renewable energy---that...

We explore how optimal emission abatement trajectories are affected by dynamic characteristics of greenhouse-gas emitting systems, such as inertia, induced innovation, and pathdependency, by formulating a compact and analytically tractable model with stylized damage assumptions to derive the...

We study clean energy subsidies in a quantitative climate-economy model. Clean energy subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient subsidy equals the marginal external cost of dirty energy multiplied by the marginal...

We study clean energy subsidies in a quantitative climate-economy model. Clean en-ergy subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient subsidy equals the marginal external cost of dirty energy multiplied by the...

We propose and implement a procedure to optimally hedge climate change risk. First, we construct climate risk indices through textual analysis of newspapers. Second, we present a new approach to compute factor mimicking portfolios to build climate risk hedge portfolios. The new mimicking...
