摘要 | The "green paradox" literature points out that environmental policies which are anticipated to become gradually more stringent over time may induce a more rapid extraction of fossil fuels, thus having a detrimental effect to the environment. The manifestation of such phenomena has been extensively studied in the case of taxes directly applied to the extraction of a polluting non-renewable resource and of subsidies applied to its non-polluting substitutes. This paper examines the effects of subsidies to "clean" R&D activities, aimed to improve the productivity of non-polluting substitutes. We borrow standard assumptions from the directed-technical-change literature to take a full account of the private incentives to perform R&D and of the patterns of complementarity/substitutability between dirty resource and clean non-resource sectors. We show that a gradual increase in relative subsidies to clean R&D activities does not have the adverse green paradox effect, which contradicts an earlier made conjecture. Instead, the presence of several R&D sectors implies arbitrages which give rise to other quite paradoxical results. However substitutable or complementary sectors are, and whatever the induced technological bias is, clean-R&D-support policies always enhance the long-run productivity of the resource and thus result in a less rapid extraction. |
