Too Little Oil, Too Much Coal: Optimal Carbon Tax and when to Phase in Oil, Coal and Renewables [PDF]
Our main message is that it is optimal to use less coal and more oil once one takes account of coal being a backstop which emits much more CO2 than oil. The way of achieving this is to have a steeply rising carbon tax during the initial oil-only phase, a
