We develop a model of optimal carbon taxation and redistribution taking into account horizontal equity concerns by considering heterogeneous energy efficiencies. By deriving first- and secondbest rules for policy instruments including carbon taxes, transfers and energy subsidies, we then...

Novel Carbon Dioxide Removal (CDR) technologies have seen a first wave of deployment, driven by investments through voluntary carbon markets and by specific support policies. To sustain the momentum, a credible long-term policy path is urgently needed to lead removal technologies through the...

The social cost of carbon is the central economic measure for aggregate climate change damages and functions as a metric for optimal carbon prices. Previous literature shows that inequality significantly influences the level of the social cost of carbon, but mostly neglects a major source of...

This paper provides a formal survey of price and quantity instruments for mitigating global warming. We explicitly consider policies' impact on the incentives of resource owners who maximize their profits intertemporally. We focus on the informational and commitment requirements of the...

Lemoine and Rudik (2017) argue that it is efficient to delay reducing carbon emissions, because there is substantial inertia in the climate system. However, this conclusion rests upon misunderstanding the relevant climate physics: there is no substantial lag between CO2 emissions and warming,...

This paper highlights the importance of carbon dioxide removal (CDR) technologies for climate policy. We first describe their role in iconic transformation pathways and discuss removal costs and storage duration of different technologies. Based on economic principles, we characterize optimal...

We investigate conditions that aggravate market failures in energy innovations, and suggest optimal policy instruments to address them. Using an intertemporal general equilibrium model we show that 'small' market imperfections may trigger a several decades lasting dominance of an incumbent...

Long-term commitment is crucial for the dynamic efficiency of intertemporal cap-and-trade programs. Discretionary interventions in such programs could destabilize the market, and necessitate subsequent corrective interventions that instigate regulatory instability (Kydland and Prescott, 1977)....

Imperfect altruism between generations may lead to insufficient capital accumulation. We study the welfare consequences of taxing the rent on a fixed production factor, such as land, in this setting. We prove that taxing the rent is welfare-enhancing as it increases capital investment. This...
