This paper examines the optimal setting of environmental taxes in economies where other, distortionary taxes are … optimal rate is lower the larger are the distortions posed by ordinary taxes. Numerical results indicate that previous studies … may have seriously overstated the size of the optimal carbon tax by disregarding pre-existing taxes …

We find that interactions with pre-existing taxes influence the … effect leads to significantly higher efficiency costs than what would apply in a first-best world with no pre-existing taxes …. Revenue-raising regulations (taxes) enjoy a revenue-recycling effect that offsets much of the tax-interaction effect, but non …
