Issues in environmental justice within the European Union

This paper surveys pressing issues facing current and future social policies in the European Union (EU) at the juncture of social justice demands and environmental concerns. European policy-makers have in fact only recently acknowledged the notions of environmental justice and environmental inequalities, which have been part of the US policy arsenal for almost two decades. Yet, challenges to equality and fairness in the environmental domain are many and growing within the European Union. After having defined environmental justice and environmental inequalities in the European context, the paper addresses two contemporary dimensions of those challenges for EU social policies: vulnerability and exposure to environmental disaster and risk; and fairness in environmental taxation and the related issue of fuel poverty.     

Income inequality and the development of environmental technologies

Within rich countries, a large dispersion in the capacity of generating environmental innovations appears correlated to the level of inequality. Previous works analyze the relationship between inequality and environmental quality in a static setting. This paper builds a dynamic model more suitable to analyze technological externalities driven by the emergence of a new demand for green products. Under fairly general assumptions on technology and preferences, we show that: 1. the relationship between inequality and environmental innovation is highly non-linear and crucially depends on per-capita income; 2. an excessive inequality harms the development of environmental technologies especially in rich countries. Key to our results is the fact that externalities generated by pioneer consumers of green products benefit the entire population only for relatively low income distances. The empirical analysis robustly confirms our theoretical results, that is: whereas for rich countries inequality negatively affects the diffusion of innovations, per-capita income is paramount in poorer ones.     

Sectoral systems of environmental innovation: An application to the French automotive industry

This article seeks to show how a sectoral system approach may contribute to the analysis of the determinants of environmental innovations. By using Malerba's [F. Malerba: Sectoral systems of innovation and production, Res. Policy Vol. 102, 845-859, (2002)] concept of sectoral system of innovation and production, we develop a sectoral framework based on three building blocks: technological regimes, demand conditions and environmental and innovation policy. Within this framework, the sectoral patterns of environmental innovation result from the interplay between these three blocks. The conceptual framework is applied to the case of the French automotive industry, with a specific focus on the development of low emission vehicles. The analysis shows how technological regime and demand conditions lead to technological inertia, and so to a strong persistence of the dominant design. Finally, environmental and innovative policy are considered in an integrated way, so that we can study how they influence technological regime and demand conditions, and in the meantime how they are conditioned by these two blocks.     

Standard Oriented Environmental Policy: Cost-Effectiveness and Incentives for 'Green Technology'

Abstract. In their seminal 1971 paper, W. J. Baumol and W. E. Oates analyzed effluent charges and 'command and control' regarding their ability to attain a given standard of environmental quality at minimum cost. In the subsequent literature,transferable discharge permits (TDPs) have been added to the portfolio of standard oriented environmental policy instruments. We place these instruments in a dynamic context. Here, cost minimization is defined in an intertemporal setting allowing for induced technical change. It turns out that the relative performance of alternative policy instruments regarding their 'dynamic cost-effectiveness' crucially depends on the information available to the involved agents. Under adverse informational conditions,only a TDP system with future markets is dynamically cost-effective.     

Learning or lock-in: Optimal technology policies to support mitigation

We investigate conditions that amplify market failures in energy innovations, and suggest optimal policy instruments to address them. Using an intertemporal general equilibrium model we show that ‘small’ market imperfections may trigger a several decades lasting dominance of an incumbent energy technology over a dynamically more efficient competitor, given that the technologies are very good substitutes. Such a ‘lock-in’ into an inferior technology causes significantly higher welfare losses than market failure alone, notably under ambitious mitigation targets. More than other innovative industries, energy markets are prone to these lock-ins because electricity from different technologies is an almost perfect substitute. To guide government intervention, we compare welfare-maximizing technology policies including subsidies, quotas, and taxes with regard to their efficiency, effectivity, and robustness. Technology quotas and feed-in-tariffs turn out to be only insignificantly less efficient than first-best subsidies and seem to be more robust against small perturbations.     

Information age to genetic revolution: Embodied technology transfer and assimilation — A tale of two technologies

In this paper, a fifteen regions-fifteen sectors global Computable General Equilibrium (CGE) model is calibrated. It offers quantitative enumeration of 5% exogenous biotechnological invention in USA in genetically modified crops namely, maize grains and soybean. Consequently, it results in endogenously transmitted productivity gains via traded intermediates in user sectors in donor and recipient regions. Sustained absorption and domestic usability of transgenic varieties depend on constellation of: human capital-induced absorptive capacity, governance, and structural congruence between source and recipients contingent on technology infrastructure and socio-institutional parameters. Such innovations result in higher production, welfare and global trade. Also, concomitant 4% exogenous productivity shock in information technology along with 5% productivity growth in the agro-biotech sectors further enhances such simulated impacts on global production and welfare. Regions with larger extent of technology capture aided by higher human capital, better governance, conducive institutional-structural features, and superior technological expertise perform better.     

Growth effects of environmental policy when pollution affects health

In this paper, we develop a R&D-based growth model with a pollution externality and a health production sector. We study how health-impairing pollution affects long term growth, and the effect of an emissions' reduction policy (tax). We show that a tighter environmental tax has positive effects on growth via two channels. On the one hand, it improves workers' health and, thereby, productivity; on the other hand, it induces a reallocation of resources towards R&D and, thereby, higher research intensity. The size of the growth effect of a tighter environmental tax, and the level of the optimal environmental tax, are both positively correlated with the weight individuals place on health relative to consumption. As for welfare, a tighter environmental tax brings about utility gains in the long run and, potentially, also in the short run.     

Explaining the variation in household recycling rates across the UK

Household waste recycling rates vary significantly both across and within regions of the UK. This paper attempts to explain the variation by using a new data set of waste recycling rates and policy determinants for all of the UK's 434 local authorities over the period 2006Q2 to 2008Q4. Our results suggest that the method of recycling collection chosen by policy makers is an important factor influencing the recycling rate. We also find an inverse relationship between the frequency of the residual waste collection and the recycling rate.     

Economic and environmental impacts of trade liberalization: The case of Indonesia

In recent years, there has been a growing interest in the environmental impacts of trade liberalization. This paper provides further discourse in this area with a study on Indonesia and its trade agreements with Japan (IJEPA) and ASEAN (AFTA). A static global CGE model, known as the Global Trade Analysis Project, was used to project the Indonesian economy to the year 2022, with and without tariff reforms agreed under the agreements. Environmental impacts are assessed using different pollution indicators—air, water and waste. The study suggests that Indonesia would grow rapidly over the period considered with a large deterioration in its environment. Following these, however, the agreements only have a marginal positive impact on Indonesia's output but with a noticeable increase in trade flows and signs of trade diversion. Overall AFTA has a greater impact on the Indonesian economy compared to IJEPA. Similarly, the impact of trade liberalization on the environment is marginal. On the whole, tariff reform is inducing air pollution and reducing water pollution. In conclusion, the study suggests that Indonesia's participation in the AFTA and IJEPA agreements is not likely to bring drastic changes to her economic and environmental performance.     

International transmission of environmental policy: A New Keynesian perspective

In this paper we examine the international transmission of environmental policy using a New Keynesian model of the global economy. We first consider the case in which the quality of the environment affects utility, but not productivity. This allows us to look at the trade-off between environmental quality and output. We then consider the case in which the quality of the environment increases productivity but does not affect utility. Our main results show that in both cases a unilateral implementation of a more stringent environmental policy by the domestic country raises foreign welfare under a benchmark parameterization. Our modeling strategy allows an analysis of how nominal rigidities interact with the implementation of environmental reforms, by allowing the domestic country to shift, through exchange rate depreciation, parts of the costs of more stringent environmental policies to the foreign one.     

Growth,Convergence, and Social Cohesion in the European Union

The aim of this paper is to analyze the economic and social cohesion in the European Union. There are different factors to explain the convergence process and besides, empirical findings are not conclusive. To the European Union, GDP per head interregional differences have decreased for certain periods but it has remained unchanged or even increased for others periods. The second report on the economic and social cohesion indicates that some decades are necessary to eliminate regional differences. These differences in regional GDP are mainly explained by differences in their productive structures, degree of innovate activity, communications structures, which depend on the relative level of transport infrastructures, and manpower qualifications. This analysis allows us to obtain some conclusions to the economic policies and the social cohesion. A preliminary version of this paper was presented in the 57th International Atlantic Conference, held in Lisbon, Portugal, March 10–14, 2004.     

Information technology and efficiency in trucking

Abstract .  We develop an econometric model to estimate the impact of Electronic Vehicle Management Systems ( EVMS ) on the load factor ( LF ) of heavy trucks. This technology is supposed to improve capacity utilization. The model is estimated on the Quebec subsample of the 1999  National Roadside Survey . The  LF  is explained as a function of truck, trip, and carrier characteristics. We show that the use of  EVMS  results in an increase of 16 percentage points of  LF  on backhaul trips. However, we also find that there is a rebound effect on fronthaul movements, with a reduction of  LF  by about 7.6 percentage points.     

A model of technological breakthrough in the renewable energy sector

Models with induced technological change in the energy sector often predict a gradual expansion of renewable energies, and a substantial share of fossil fuels remaining in the energy mix through the end of our century. However, there are historical examples where new products or technologies expanded rapidly and achieved a high output in a relatively short period of time. This paper explores the possibility of a ‘technological breakthrough’ in the renewable energy sector, using a partial equilibrium model of energy generation with endogenous R&D. Our results indicate, that due to increasing returns-to-scale, a multiplicity of equilibria can arise. In the model, two stable states can coexist, one characterized by a lower and one by higher supply of renewable energy. The transition from the low-output to the high-output equilibrium is characterized by a discontinuous rise in R&D activity and capacity investments in the renewable energy sector. The transition can be triggered by a rise in world energy demand, by a drop in the supply of fossil fuels, or by policy intervention. Under market conditions, the transition occurs later than in the social optimum. Hence, we identify a market failure related to path-dependence and technological lock-in, that can justify a strong policy intervention initially. Paradoxically, well-intended energy-saving policies can actually lead to higher emissions, as they reduce the incentives to invest in renewable energies by having a cushioning effect on the energy price. Hence, these policies should be supplemented by other instruments that restore the incentives to invest in renewable energies. Finally, we discuss the influence of monopoly power in the market for innovations. We show that market power can alleviate the problem of technological lock-in, but creates a new market failure that reduces static efficiency.     

Inequality,growth, and environmental quality trade‐offs in a model with human capital accumulation

This paper develops a simple endogenous growth model where pollution exposure and vulnerability are unequally spread across the population, and growth and distribution are endogenous. In this set‐up, we investigate whether trade‐offs between growth, distributional, and environmental concerns may emerge. We show that a tighter environmental policy reduces income inequality and can improve both growth and total welfare. Immediate welfare losses, though, do occur, and are larger for countries that start at low levels of environmental quality (e.g. developing countries).     

Policy mechanism choice for environmental management by non-commercial “lifestyle” rural landholders

For some environmental assets in rural areas, the landholders who are having the biggest impact are people with small holdings and an emphasis on lifestyle rather than commercial gains from their land. This paper aims to better understand the motivations and likely responses to policy for lifestyle landholders in Australia, in order to assess which policy mechanisms, if any, are likely to be most efficiently used to influence their land management. Through face-to-face interviews, we find that lifestyle landholders have important differences from commercial farmers, including much smaller properties, a stronger interest in environmental outcomes, a lack of land-management skills and a lack of time for land-management activities. From the perspective of environmental policy programs, engaging with lifestyle landholders is likely to involve higher transaction costs, and there are likely to be higher learning and transition costs per unit area. A framework for selection of policy tools is modified to take account of these findings. It is concluded that the prospects for worthwhile public investments in land-use changes by lifestyle landholders are lower than for commercial landholders.
