In this paper, I develop a two-stage game of pollution abatement technology adoption in a Cournot oligopoly to investigate a firm’s decision to adopt pollution abatement technology. In particular, I study the adoption incentives and welfare implications of popular environmental policies, namely emission fees and quotas. Tradeable permits result in identical outcomes to emission fees. Within each policy regime, the conditions for Nash equilibria are identified where both firms invest in the green technology, neither firm invests in the technology, or only one firm invests. The following extensions are also analyzed: asymmetric adoption costs, increase in the marginal cost of production from adoption, and a type-dependent fee where adoption reduces the emission fee. Social welfare under an emission fee is identical to that under a quota. However, when policy is (not) stringent, firms are more willing to adopt expensive technology under a fee (quota) than under a quota (fee, respectively).

Reallocation Of Resources

AbstractWhile 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.

Abstract According to the Pollution Haven Hypothesis (PHH), weak environmental policies improve a country's comparative advantage in the polluting sector, thus promoting its expansion. In this paper, we develop a neo-classical general equilibrium model with two goods and two factors and show that the relationship between environmental policies and comparative advantage can be ambiguous. We focus entirely on emission caps or command and control (CAC) programs of regulation and treat abatement as equivalent to a technological retardation. We show that when the technological retardation is Hick neutral, the PHH holds and the Heckscher Ohlin Samuelson (HOS) theorem determines trade patterns between a capital-abundant country and a labor-abundant country that follow different environmental policies. If pollution abatement is capital biased in the polluting sector, the standard trade theorems and the PHH may not hold. The paper derives a sufficient condition under which the PHH would hold. However, if this condition is violated, the PHH as well as the HOS theorem may not hold.

The Impact

Over use of chemical inputs and exploitation of natural resources have degraded our ecosystem to a large extent. Our water bodies are drastically affected, especially due to the impact of heavy metal loading. The biomagnification that results from these difficult to degrade metals is naturally affecting the human health. The physical and chemical methods commonly employed for water purification are not only highly expensive but also further aggravate the pollution problem. Hence, all efforts must be taken to exploit the emerging green technology approach in pollution remediation. Several aquatic plants have specific affinity towards heavy metals and they flourish well in this contaminated environment. The common mechanisms of phytoremediation and varied type of aquatic plants with high remediation potential are reviewed in this chapter.
