We derive the optimal unilateral policy in a general equilibrium model of trade and climate change where one region of the world imposes a climate policy and the rest of the world does not. A climate policy in one region shifts activities - extraction, production, and consumption - in the other...

A central question in climate policy is whether early investments in low-carbon technologies are a useful first step towards a more effective climate agreement in the future. We introduce a climate cooperation model with endogenous R&D investments where countries protect their international...

In a dynamic, three-region environmental multi-sector general equilibrium model (called EMuSe), we find that carbon pricing generates a recession initially as production costs rise. Benefits from lower emissions damage materialize only in the medium to long run. A border adjustment mechanism...

To reach climate neutrality, carbon emissions from the production of basic materials need to be significantly reduced. For governments' support measures to be consistent with their World Trade Organization obligations, they need to be compatible with the WTO's Agreement on Subsidies and...

Carbon taxes are advocated as efficient fiscal and environmental policies, but they have proven difficult to implement. One reason is that carbon taxes can aggravate poverty by increasing prices of basic goods and services such as food, heating, and commuting. Meanwhile, cash transfer programs...

An important source of political opposition to measures aimed at reducing emissions of greenhouse gases (GHGs) arises from concerns over their negative effects on the competitiveness of domestic firms, especially those that are energy-intensive and exposed to competition from foreign producers....

One reason carbon prices are difficult to implement is that they might imply high additional costs on poor and vulnerable households. In response, studies often highlight that recycling revenues through cash transfers can render carbon pricing reforms progressive. This neglects that existing...
