This paper postulates the conceptually useful allegory of a futuristic "World Climate Assembly" (WCA) that votes for a single worldwide price on carbon emissions via the basic democratic principle of one-person one-vote majority rule. If this WCA framework can be accepted in the first place,...

We extend the model of Fullerton, Karney, and Baylis (2012 working paper) to explore cost-effectiveness of unilateral climate policy in the presence of leakage. We ignore the welfare gain from reducing greenhouse gas emissions and focus on the welfare cost of the emissions tax or permit scheme....

Climate change is considered as one of the major global challenges. Although countries past and future contributions to the accumulation of greenhouse gases in the atmosphere are different, all countries are affected, but not necessarily in the same way (e.g. rising sea levels). This is the...

An estimate of the social cost of carbon (SCC) is key to climate policy. But how should we estimate the SCC? A common approach is to use an integrated assessment model (IAM) to simulate time paths for the atmospheric CO2 concentration, its impact on global mean temperature, and the resulting...

Estimating the cost to society from a ton of carbon dioxide (CO2) released into the atmosphere requires connecting a model of the climate system with a representation of the economic and social effects of changes in climate, as well as the valuation and aggregation of diverse, uncertain impacts...

The United States Government recently concluded a year-long process to develop a range of values representing the monetized damages associated with an incremental increase in carbon dioxide (CO2) emissions, commonly referred to as the social cost of carbon (SCC). These values are currently used...

The present study examines the assumptions, modeling structure, and preliminary results of DICE-2023, the revised Dynamic Integrated Model of Climate and the Economy (DICE), updated to 2023. The revision contains major changes in the carbon and climate modules, the treatment of non-industrial...

This paper provides stated preference (SP) estimates of the average social cost of carbon (ASCC) for use in evaluation of the benefits and costs of climate policy. Based on a U.S. nationally representative survey, we find an average individual willingness-to-pay (WTP) of $1,116 per year to keep...
