Modelling the nonlinear relationship between CO2 emissions from oil and economic growth

The purpose of this paper is to examine the relationship between carbon dioxide (CO2) emissions from oil and GDP, using panel data from 1971 to 2007 of 98 countries. Previous studies have discussed the environmental Kuznets curve (EKC) hypothesis, but little attention has been paid to the existence of a nonlinear relationship between these two variables. We argue that there exists a threshold effect between the two variables: different levels of economic growth bear different impacts on oil CO2 emissions. Our empirical results do not support the EKC hypothesis. Additionally, the results of short-term analyses of static and dynamic panel threshold estimations suggest the efficacy of a double-threshold (three-regime) model. In the low economic growth regime, economic growth negatively affects oil CO2 emissions growth; in the medium economic growth regime, however, economic growth positively impacts oil CO2 emissions growth; and in the high economic growth regime, the impact of economic growth is insignificant.     

Factors Behind the Environmental Kuznets Curve. A Decomposition of the Changes in Air Pollution

The environmental Kuznets curve theory suggeststhat economic growth in the long run may reduceenvironmental problems. In this article, we usea decomposition analysis to isolate eightdifferent factors, in order to investigate theorigins of changes in emissions to air over theperiod from 1980 to 1996. Among these factorsare economic growth, changes in the relativesize of production sectors and changes in theuse of energy. Given constant emissions perproduced unit, economic growth alone would havecontributed to a significant increase in theemissions. This potential degradation of theenvironment has been counteracted by first ofall more efficient use of energy and abatementtechnologies. In addition, the substitution ofcleaner for polluting energy types and othertechnological progressions and politicalactions have reduced the growth in emissions.Consequently, the growth in all emissions hasbeen significantly lower than economic growth,and negative for some pollutants.The results indicate that policymakers mayreduce emissions considerably through creatingincentives for lower energy use andsubstitutions of environmental friendly forenvironmental damaging energy types, inaddition to support environmental friendlyresearch or to conduct direct emission reducingactions, such as abatement requirements orbanning of environmental damaging products.This is particularly relevant to countries andsectors with relatively high energy intensitiesand low pollution abatement.     

The Superiority of Environmental Federalism in the Presence of Lobbying and Prior Tax Distortions

It is generally believed that environmental federalism tends to generate greater pollution emissions than centralized policymaking. This paper demonstrates that the opposite can occur in the presence of lobbying. Although the decentralized regime gives rise to a tax‐interaction effect, which induces policymakers to set lax environmental policies, it may also reduce the political pressure on enlarging allowed emissions. If the latter outweighs the former, then the decentralized regime will generate less pollution than the centralized regime. Moreover, we also show that the decentralized regime can be more efficient than the centralized regime, which provides an alternative theoretical support for the superiority of environmental federalism.     

Using Tradeable Permits to Achieve Sustainability in the World's Large Cities: Policy Design Issues and Efficiency Conditions for Controlling Vehicle Emissions, Congestion and Urban Decentralization with an Application to Mexico City

Many large cities in the world have serious ground level ozone problems, largely the product of vehicular emissions and thus the argued unsustainability of current urban growth patterns is frequently blamed on unrestricted private vehicle use. This article reviews Mexico City's experience with vehicle use restrictions as an emissions control program and develops the conditions for optimal quantitative restrictions on vehicle use and for complementary abatement technologies. The stochastic nature of air pollution outcomes is modelled explicitly in both the static and dynamic formulations of the control problem, in which for the first time in the literature the use of tradeable vehicle use permits is proposed as a cost-effective complement to technological abatement for mobile emissions control. This control regime gives the authorities a broader and more flexible set of instruments with which to deal more effectively with vehicle emissions, and with seasonal and stochastic variation of air quality outcomes. The market in tradeable vehicle use permits would be very competitive with low transactions costs. This control policy would have very favorable impacts on air quality, vehicle congestion and on urban form and development. Given the general political resistance to environmental taxes, this program could constitute a workable and politically palatable set of policies for controlling greenhouse gas emissions from the transport sector.     

The impact of financial development,income, energy and trade on carbon emissions: Evidence from the Indian economy

This paper examines the long-run equilibrium and the existence and direction of a causal relationship between carbon emissions, financial development, economic growth, energy consumption and trade openness for India. Our main contribution to the literature on Indian studies lies in the investigation of the causes of carbon emissions by taking into account the role of financial development and using single country data. The results suggest that there is evidence on the long-run and causal relationships between carbon emissions, financial development, income, energy use and trade openness. Financial development has a long-run positive impact on carbon emissions, implying that financial development improves environmental degradation. Moreover, Granger causality test indicates a long-run unidirectional causality running from financial development to carbon emissions and energy use. The evidence suggests that financial system should take into account the environment aspect in their current operations. The results of this study may be of great importance for policy and decision-makers in order to develop energy policies for India that contribute to the curbing of carbon emissions while preserving economic growth.     

Emissions Pricing Policies and Business Cycles: Fixed vs. Variable Tax Regimes

As by-products, emissions follow economic fluctuations. Ignoring this fact in environmental policies can lead to unexpected emissions fluctuations and an increase in intervention costs. Using a real business cycle model, we compare two policies: a fixed tax policy where the price is constant over time and a variable tax regime where the tax rate is set at the beginning of each period. We find that while both programs result in lower emissions, a variable tax regime is preferable since first, it can ensure that the maximum welfare is always achieved, and second, it is more effective in stabilising emissions.     

Energy consumption,economic growth and environmental degradation in OECD countries

The interdependence among energy consumption, economic growth and environmental degradation has become an important public policy priority among OECD countries. Yet, the related literature provides conflicting results when describing the dynamic nature of such a relationship and the way it affects countries' development path. Using a sample of 35 OECD countries over the period 2000–2014, we find that economic growth and energy consumption patterns contribute to the enhancement of countries' environmental performance levels. In contrast to a large stream of empirical research, our findings highlight that countries' economic development path and their energy consumption patterns have started to align with their environmental policies. The results are robust since we utilize different aspects of countries' environmental degradation such as carbon dioxide emissions, ecological footprints and countries' environmental performance levels. Finally, the analysis of the dynamic interrelations among countries' energy consumption, economic growth and environmental degradation levels, reveals the necessity to promote sustainable development through a coexistence rather than through a trade-off mechanism.     

Environmental tax policy in a model of growth cycles

Summary. The purpose of this paper is to consider environmental taxation which would control emissions of firms in a model of growth cycles. In the model presented below, the economy may experience two phases of growth and environmental quality: “the no-innovation growth regime” and “the innovation-led growth regime”. Aggregate capital and environmental quality remain constant in the no-innovation growth regime, while they perpetually increase in the innovation-led growth regime. The paper shows that the tax plays a key role in determining whether the economy stably converges to one of the two regimes or fluctuates permanently between them. It also shows that there is a critical level of the tax and that the economy obtains higher growth rates of capital and environmental quality by raising (or reducing) the tax if the initial tax is below (or above) the critical level.

Is reducing energy intensity enough to put the oil-rich GCC states on a more sustainable environmental path?

Although energy wealth rankings place the six Gulf Cooperation Council (GCC) countries among the richest in the world, these economies face unsustainable growth in energy use and continuous environmental degradation. This paper examines the long-run relationship between per capita \(\hbox {CO}_2\) emissions and energy intensity in the GCC, while controlling for economic activity, the size of the manufacturing sector, and institutional qualities. We use heterogeneous panel techniques that account for heterogeneity and cross-country dependence for the period 1971–2011. We find that energy intensity and emissions are cointegrated in all GCC countries and that conservation and energy efficiency policies have greater potential in reducing emissions in Kuwait, Oman, and the UAE. A regional goal of mitigating emissions by 10% would require a reduction in energy intensity by 12%, on average. Last, we find that judiciary independence is an essential institutional quality that ensures the successful implementation and the stringent enforcement of long-term environmental policies.     

Economic growth and greenhouse gas emissions

Recent empirical research has examined the relationship between certain indicators of environmental degradation and income, concluding that in some cases an inverted U-shaped relationship, which has been called an environmental Kuznets curve (EKC), exists between these variables. Unfortunately, this inverted U-shaped relationship does not hold for greenhouse gas emissions. One explanation of the absence of EKC-like behavior in greenhouse gas emissions is that greenhouse gases are special pollutants that create global, not local, disutility. But the international nature of global warming is not the only reason that prevents de-linking greenhouse gas emissions from economic growth. The intergenerational nature of the negative impact of greenhouse gas emissions may have also been an important factor preventing the implementation of greenhouse gas abatement measures in the past. In this paper we explore the effect that the presence of intergenerational spillovers has on the emissions–income relationship. We use a numerically calibrated overlapping generations model of climate–economy interactions. We conclude that: (1) the intertemporal responsibility of the regulatory agency, (2) the institutional capacity to make intergenerational transfers and (3) the presence of intergenerationally lagged impact of emissions constitute important determinants of the relationship between economic growth and greenhouse gas emissions.     

The Timing of Environmental Policy: A Note on the Role of Product Differentiation

We examine the role that product differentiation can play in the design of environmental policy under full commitment and no commitment on the part of the environmental regulator. We consider a setting with two firms selling a differentiated product which generates pollution through emissions. Firms can reduce their emissions by undertaking abatement activities while an environmental regulator taxes emissions. The main results are: (1) When products are highly differentiated, the optimal time-consistent (no commitment) tax is always lower than the optimal pre-commitment tax. As the degree of product differentiation decreases, for relatively efficient abatement technology and high damages, the time-consistent emission tax exceeds the optimal pre-commitment one. (2) Abatement when product differentiation is extensive is higher under the time-consistent regime unless the abatement technology is extremely efficient. The same ranking applies to social welfare. However, as products become more and more similar, these results are (partially) reversed and pre-commitment could lead to both higher levels of abatement and welfare.     

Economic growth with environmental damage and technical progress

The papers on economic growth with environmental constraints usually ignore the effect of technical progress, this results in static steady state solutions. This paper examines the problem of optimal economic growth with environmental damage, technical progress taken into account, which produces a steady state solution that corresponds to an equilibrium growth, with non-constant emissions and pollutant stock. As a means of steering the economy along the optimal path, two types of tradeable pollution permits are analyzed. The method of stabilizing the optimal path, leading to a steady state, is suggested.     

Testing the null hypothesis of no regime switching with an application to GDP growth rates

This paper presents tests for the null hypothesis of no regime switching in Hamilton’s (Econometrica 57:357–384, 1989) regime switching model. The test procedures exploit similarities between regime switching models, autoregressions with measurement errors, and finite mixture models. The proposed tests are computationally simple and, contrary to likelihood based tests, have a standard distribution under the null. When the methodology is applied to US GDP growth rates, no strong evidence of regime switching is found.

Environment-Friendly Behaviour and Competitiveness: A Study of Pulp and Paper Industry in India

This paper seeks to examine the relationship between competitiveness and environment-friendly behaviour of producers under an economic liberalisation regime. For that purpose, it employs a probit model and estimates the influence of the prime movers of industrial growth such as technical change and economies of scale on environmental degradation. The empirical results of the study of pulp and paper industry, identified as one of the most polluting industries in India, indicate that these variables, as the key players of competitiveness improvement, have positive influence on environment-friendly behaviour. Such findings, therefore, fail to provide support to a view that articulates ruthless exploitation of the environment under economic liberalisation programme.     

Which border taxes? Origin and destination regimes with fiscal competition in output and emission taxes

This paper posits a two-stage game in tax regime and tax rates to study the property of second-best emission and output taxes in a two-country world with an atmospheric externality. It shows that (i) either the destination–destination or the origin–origin tax regime may constitute the subgame perfect Nash equilibrium of this game; (ii) either regime may Pareto-dominate the other; (iii) it is possible to have a prisoner's dilemma game where the origin–origin regime Pareto-dominates but the choice of the destination regime is the dominant strategy for each country. Other results include (iv) under origin–origin regime: the output tax is used for fiscal competition; the emission tax is set at a rate equal to the (national) marginal social damage of emissions; and public goods are provided suboptimally. (v) Under destination–destination regime: the output tax is ineffective as an instrument for fiscal competition; the emission tax is used not only for combating pollution but also for tax competition; the tax is set at a rate below the (national) marginal social damage of emissions; emissions are pushed above their closed-economy level; the provision of public goods are optimal.     

Energy consumption,carbon emissions,and economic growth in India: Evidence from directed acyclic graphs

This study investigates the temporal linkages among economic growth, energy consumption, and carbon emissions for India during the period 1970–2008 using recently developed methods of out-of-sample Granger causality tests and directed acyclic graphs (DAG). Building on the data-driven DAG representation, we uncover the contemporaneous causal patterns between economic activities and environmental pollutants, which is first documented in the literature and could further improve the investigation of the dynamic linkage pattern. The results show that energy consumption uni-directionally Granger causes carbon emissions and economic growth, while there is a bidirectional causality between carbon emissions and economic growth. We also find that trade openness is one of the important determinants of energy consumption and carbon emissions. Some important policy implications are also discussed.     

How does environmental performance affect financial performance? Evidence from Japanese manufacturing firms

This paper examines the effects of environmental performance on financial performance using the data of Japanese manufacturing firms from 2004 to 2008. As the environmental performance, our study considers the two different environmental issues of waste and greenhouse gas emissions in capturing the effects of corporate environmental management on financial performance. In addition, to clarify how each financial performance responds to a firm's effort in dealing with different environmental issues, we utilize many financial performance indices reflecting various market evaluations. Our estimation results show the different effects of each environmental performance on financial performance. Waste emissions do not generally have significant effects on financial performance. On the other hand, greenhouse gas reduction leads to an increase in financial performance in the whole sample and clean industries, although it does not have significant effects on financial performance in dirty industries. Furthermore, as the firm growth rate increases, the partial effects of waste emissions on financial performance decrease, whereas the partial effects of greenhouse gas emissions on financial performance increase.     

Trade,Growth, and Environmental Quality*

This paper examines linkages between international trade, environmental degradation, and economic growth in a dynamic North–South trade game. Using a neoclassical production function subject to an endogenously improving technology, North produces manufactured goods by employing labor, capital, and a natural resource that it imports from South. South extracts the resource using raw labor, in the process generating local pollution. We study optimal regional policies in the presence of local pollution and technology spillovers from North to South under both non‐cooperative and cooperative modes of trade. Non‐cooperative trade is inefficient due to stock externalities. Cooperative trade policies are efficient and yet do not benefit North. Both regions gain from improved productivity in North and faster knowledge diffusion to South regardless of the trading regime.     

Regulating an Externality-Generating Utility Environmental Taxes Under Limited Information

Global warming is currently an important item on most nationalenvironmental agendas. In many countries, coal-fired electricity generatingstations represent an important source of greenhouse gases. We examinehow regulations to curb emissions affect public utility pricing regulationwhen regulators act non-cooperatively. We show that, when there is limitedinformation on fixed abatement costs, an environmental regulator prefersan emission tax over an output tax or a lump sum environmental tax. Thepublic utility regulator prefers the lump sum tax regime.
