    Abstract: Do Environmental Protection Agency (EPA) bureaucrats represent the general public or are they more in line with an interest group? We study preferences for environmental policy using a choice experiment (CE) on three populations; the general public, Swedish EPA bureaucrats, and recreational anglers. We also test for existence of multiple preference orderings, i.e., whether responses differ depending on the decision role assigned. Half of the respondents were asked to choose the alternatives that best corresponded with their opinion, and the other half was asked to take the role of a policymaker and make recommendations for environmental policy. The SEPA bureaucrats have the highest marginal willingness to pay (MWTP) to improve environmental quality. These differences are robust and not due to differences in socio-economic characteristics across the populations. We found little evidence of multiple preference orderings, but in one case the difference in MWTP between the two roles was substantial.

    Abstract: We use the forward-looking information from the US and global capital markets to estimate the economic impact of long-run temperature fluctuations. We find that global warming has a significant negative effect on asset valuations and that temperature risks carry a negative price. We also find that the negative elasticity of equity prices to temperature risks have been increasing over time, which suggests that the impact of climate change on the macro-economy has been rising. We use our empirical evidence to calibrate a long-run risks model with temperature-induced disasters in future output and growth and quantify the social cost of carbon emissions. The model simultaneously matches the projected temperature path, the observed consumption growth dynamics, discount rates provided by the risk-free rate and equity market returns, and the estimated temperature elasticity of equity prices. We show that a preference for early resolution of uncertainty and long-run impact of temperature on growth imply a significant social cost of carbon emissions.

    Abstract: The social cost of carbon (SCC) is a monetary measure of the harms from carbon emission. Specifically, it is the reduction in current consumption that produces a loss in social welfare equivalent to that caused by the emission of a ton of CO2. The standard approach is to calculate the SCC using a discounted-utilitarian social welfare function (SWF)—one that simply adds up the well-being numbers (utilities) of individuals, as discounted by a weighting factor that decreases with time. The discounted-utilitarian SWF has been criticized both for ignoring the distribution of well-being, and for including an arbitrary preference for earlier generations. Here, we use a prioritarian SWF, with no time-discount factor, to calculate the SCC in the integrated assessment model RICE. Prioritarianism is a well-developed concept in ethics and theoretical welfare economics, but has been, thus far, little used in climate scholarship. The core idea is to give greater weight to well-being changes affecting worse off individuals. We find substantial differences between the discounted-utilitarian and non-discounted prioritarian SCC.
