    Abstract In this brief note (Without holding them responsible for errors, omissions, or interpretations, I am grateful for constructive comments on an earlier version of this note by Joseph Aldy, Severin Borenstein, Maureen Cropper, Carolyn Fischer, Meredith Fowlie, Lawrence Goulder, Geoffrey Heal, N. Gregory Mankiw, Michael Mehling, Gilbert Metcalf, Adele Morris, Ian Parry, William Pizer, Simon Quemin, Andrew Schein, Richard Schmalensee, E. Somanathan, Robert Stavins, David Victor, and Gernot Wagner.), I take the initial allocation of carbon emissions as a prototype international public goods problem. Overcoming the free-rider problem in carbon emissions is central to a successful comprehensive international climate-change agreement. Volunteerism alone may go part way, but is unlikely to fully adequately overcome this free-rider problem. (The numerical values of the pledged “Nationally Determined Contributions” under the Paris Agreement are voluntary, although the Paris Agreement itself may help constructively by laying a legal foundation for participation, reporting, verification, transparency, and trust.)

    Abstract Linkage of national cap-and-trade systems is typically advocated by economists on a general analogy with the beneficial linkage of free-trade areas and on the specific grounds that linkage will ensure cost effectiveness among the linked jurisdictions. The paper analyses the less obvious effects of linkage with the bottom–up approach of the Paris Agreement where each country sets its nationally determined contribution for its own carbon dioxide ([Formula: see text]) emissions. An appropriate and widely accepted specification for the damages of [Formula: see text] emissions within a relatively short (say 5–10 year) period is that marginal damages for each jurisdiction are constant (although they can differ among jurisdictions). With this defensible assumption, the analysis is significantly clarified and yields simple closed-form expressions for all [Formula: see text] permit prices. Some implications for linked and unlinked voluntary [Formula: see text] cap-and-trade systems are derived and discussed. A numerical example illustrates the results.

    Abstract Equilibrium climate sensitivity (ECS), the link between concentrations of greenhouse gases in the atmosphere and eventual global average temperatures, has been persistently and perhaps deeply uncertain. Its ‘likely’ range has been approximately between 1.5 and 4.5 degrees Centigrade for almost 40 years (Wagner and Weitzman, 2015). Moreover, Roe and Baker (2007), Weitzman (2009), and others have argued that its right-hand tail may be long, ‘fat’ even. Enter Cox et al. (2018), who use an ‘emergent constraint’ approach to characterize the probability distribution of ECS as having a central or best estimate of 2.8 °C with a 66% confidence interval of 2.2–3.4 °C. This implies, by their calculations, that the probability of ECS exceeding 4.5 °C is less than 1%. They characterize such kind of result as “renewing hope that we may yet be able to avoid global warming exceeding 2[°C]”. We share the desire for less uncertainty around ECS (Weitzman, 2011; Wagner and Weitzman, 2015). However, we are afraid that the upper-tail emergent constraint on ECS is largely a function of the assumed normal error terms in the regression analysis. We do not attempt to evaluate Cox et al. (2018)’s physical modeling (aside from the normality assumption), leaving that task to physical scientists. We take Cox et al. (2018)’s 66% confidence interval as given and explore the implications of applying alternative probability distributions. We find, for example, that moving from a normal to a log-normal distribution, while giving identical probabilities for being in the 2.2–3.4 °C range, increases the probability of exceeding 4.5 °C by over five times. Using instead a fat-tailed Pareto distribution, an admittedly extreme case, increases the probability by over forty times.
