This paper extends the Mirrlees (1971) model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities. It is demonstrated that the optimal second-best tax on an externality-generating good should not be corrected for the marginal cost of public...

Climate is a persistent asset, bar none: changes in climate-related stocks have consequences spanning over centuries or possibly millennia to the future. To reconcile the discounting of such far-distant impacts and realism of the shorter-term decisions, we consider hyperbolic time-preferences in...

This paper derives the social cost of carbon (SCC) and its rate of change. It does so in a deterministic Ramsey model of optimal economic growth with carbon emissions from burning fossil fuels. It is shown that the determinants of the rate of change of the SCC are substantially almost identical...
