Reducing greenhouse gas emissions not only lowers expected damages from climate change but also reduces the risk of catastrophic impacts. However, estimates of the social cost of carbon, which measures the marginal value of carbon dioxide abatement, often do not capture this risk reduction benefit. Risk-averse individuals are willing to pay a risk premium, an additional amount beyond the differ...

T he 2013 Interagency Working Group on the Social Cost of Carbon (IWG) updated the U.S. social cost of carbon (SCC) for 2015 from a central value of $24 to $37 using three integrated assessment models (IAMs): DICE-2010, FUND 3.8, and PAGE09. The SCC is the additional economic damage caused by one ton of carbon dioxide. While some have questioned the increase in the SCC as too high, a thorough e...

Reducing emissions of CO2 today is expected to reduce climate damages in the future. In this paper, we examine the question of whether fighting climate change has the additional advantage of reducing the aggregate risk borne by future generations. This raises the question of the ‘climate beta’, i.e. the elasticity of climate damages with respect to a change in aggregate consumption. Using the D...

Drawing upon climate change damage functions previously proposed in the literature that we have calibrated to a common level of damages at 2.5 C, we examine the effect upon the social cost of carbon (SCC) of varying the specification of damages in a DICE-like integrated assessment model. In the absence of risk aversion, all of the SCC estimates but one agree within a factor of two. The effect o...

The marginalization not only shows the exterior face of the city in a bad light, but also causes to more irreparable and undesirable consequences. Identifying the social impacts of marginalization is one of the most important urban issues to consider. Thus, this study aims to investigate the relationship between marginalization and social damages in eastern Mazandaran province. The research met...
