The Choice of Discount Rate for Climate Change Policy Evaluation
Goulder, Lawrence H. - 2012
Distinguishing the two rates helps resolve arguments as to whether the choice of discount rate should be based on ethical considerations or empirical information (such as market interest rates), and about whether the discount rate should serve a prescriptive or descriptive role. Separating out...

The Economics of Climate Change
Goulder, Lawrence H. - 2006
Global climate change poses a threat to the well-being of humans and other living things through impacts on ecosystem functioning, biodiversity, capital productivity, and human health. This paper briefly surveys recent research on the economics of climate change, including theoretical insights...

Environmental Protection, Rare Disasters, and Discount Rates
Barro, Robert J. - 2013
Extremely low discount rates play a central role in the Stern Review's evaluation of environmental protection, and this assumption has been criticized by many economists. The Review also stresses that great uncertainty is a critical element for optimal environmental policies. An appropriate...

Minimax-Regret Climate Policy with Deep Uncertainty in Climate Modeling and Intergenerational Discounting
DeCanio, Stephen J.; Manski, Charles F.; Sanstad, Alan H. - National Bureau of Economic Research - 2022
Integrated assessment models have become the primary tools for comparing climate policies that seek to reduce greenhouse gas emissions. Policy comparisons have often been performed by considering a planner who seeks to make optimal trade-offs between the costs of carbon abatement and the...

Discounting under Disagreement
Heal, Geoffrey - 2013
A group of agents disagree about the appropriate inter temporal preferences to use when exploiting a common productive resource. They thus delegate decision making to a social planner who allocates consumption efficiently across heterogeneous individuals and over time. We define `policy...

The Social Cost of Stochastic and Irreversible Climate Change
Cai, Yongyang - 2013
There is great uncertainty about the impact of anthropogenic carbon on future economic wellbeing. We use DSICE, a DSGE extension of the DICE2007 model of William Nordhaus, which incorporates beliefs about the uncertain economic impact of possible climate tipping events and uses empirically...

On a World Climate Assembly and the Social Cost of Carbon
Weitzman, Martin - 2016
This paper postulates the conceptually useful allegory of a futuristic "World Climate Assembly" (WCA) that votes for a … emitter's single-peaked most-preferred world price of carbon emissions to the world "Social Cost of Carbon" (SCC). The second … and third propositions relate the WCA-voted world price of carbon to the world SCC. I argue that the WCA-voted price and …

Price of Long-Run Temperature Shifts in Capital Markets
Bansal, Ravi - 2016
We use the forward-looking information from the US and global capital markets to estimate the economic impact of global warming, specifically, long-run temperature shifts. We find that global warming carries a positive risk premium that increases with the level of temperature and that has almost...
