タイトル：
”Prices versus Quantities with Strategic Communication between Government and Polluting Industry”

<要　旨＞

We compare the performance of emission taxes and quotas when there are opportunities for communication between government and polluting industry. We consider a competitive industry which communicates its private information about production costs strategically to the government before the latter sets the tax rate or the quota level. We show that while under taxes the communication is completely uninformative, under quotas it can be informative because quotas create “windfall profits” for the industry through an output price increase and can thereby make the interests of the government and the industry closely aligned. We also show that by committing to auctioning a proportion of quotas, the government can improve the informativeness of communication under quotas even further. Our results imply that when environmental policies have a non-negligible effect on output price, the possibility of government-industry communication modifies Weitzman’s (1974) result in favor of quotas.
