摘要

While a large body of the literature on environmental policies has focused on the productivity impacts of regulations, less attention has been given to the link between environmental policies and market competition. In this paper, I develop a tractable model that incorporates variable mark-ups to study how a competitive environment is affected by environmental policies in a market with firm heterogeneity and endogenous abatement technology choice. The findings of this study are consistent with the Porter Hypothesis in the sense that environmental regulations motivate abatement technology adoption and enhance productivity and environmental quality. However, the productivity gain is mainly driven by reallocation of resources across firms rather than the induced abatement technological change. Tougher regulations harm the competitive environment by increasing average prices and market concentration. Social welfare also drops because in the absence of strong competition fewer variates are produced in equilibrium.

7. Competing Recombinant Technologies for Environmental Innovation: Extending Arthur’s Model of Lock-in Abstract: This article presents a model of sequential decisions about investments in environmentally dirty and clean technologies, which extends the path-dependence framework of Arthur (1989). This allows us to evaluate if and how an economy locked into a dirty technology can be unlocked and move towards the clean technology. The main extension involves the inclusion of the effect of recombinant innovation of the two technologies. A mechanism of endogenous competition is described involving a positive externality of increasing returns to investment which are counterbalanced by recombinant innovation. We determine conditions under which lock-in can be avoided or escaped. A second extension is â€œsymmetry breakingâ€ of the system due to the introduction of an environmental policy that charges a price for polluting. A final extension adds a cost of environmental policy in the form of lower returns on investment implemented through a growth-depressing factor. We compare cumulative pollution under different scenarios, so that we can evaluate the combination of environmental regulation and recombinant innovation. [O] .
