This paper compares emission taxes, subsidies, permits and credits with
respect to the incentives they create to enhance technology diffusion under
imperfect competition. Firms can adopt a "dirty" technology or a "clean"
abatement technology. When the clean and dirty products are perfect
substitutes, and clean firms face a net absolute advantage over dirty firms,
permits and taxes provide the strongest incentive, followed by credits and
subsidies respectively. This ranking order is reversed if there is a
distortion on output. Subsidies can neutralize this distortion; subsidies
stimulate output supply, which would normally be lower than optimal under
perfect competition.
