In this reply to the comment by Gerlagh, we confirm an error in our estimate of the certainty-equivalent social cost of carbon (SCC) reported in Newbold et al. (2013), and we discuss the underlying conceptual difficulties that arise in conducting a social welfare analysis when preferences are...

The “social cost of carbon” (SCC) is the present value of the future stream of damages from one additional ton of carbon emissions in a particular year. This paper develops a simple model for calculating the SCC and compares estimates of the SCC under certainty and uncertainty. Our model...

The "social cost of carbon" (SCC) is the present value of the stream of future damages from one additional unit of carbon emissions in a particular year. This paper develops a rapid assessment model for the SCC. The model includes the essential ingredients for calculating the SCC at the global...

It has often been stated that current studies aimed at understanding the magnitude of optimal climate policy fail to adequately capture the potential for “catastrophic” impacts of climate change. While economic modeling exercises to date do provide evidence that potential climate...
