Finally we question the standard use of infinitely-lived, single-agent models, which assume, unrealistically, intergenerational altruism in determining optimal abatement policy. Their prescriptions can differ, potentially dramatically, from those needed to correct the negative climate...

The 2015 Paris Accord is meant to control our planet's rising temperature. But it may be doing the opposite in gradually, rather than immediately reducing CO2 emissions. The Accord effectively tells dirty-energy producers to "use it or lose it." This may be accelerating their extraction and...

In this paper I argue that early action policies that focus on early actual emission reductions will tend to distort abatement investment decisions and thereby inflate the national compliance cost of a greenhouse gas emissions reduction target. Compliance cost savings stem from well-planned...
