Economic Instruments and Induced Innovation: The Case of End-of-Life Vehicles European Policies

The paper addresses the dynamic-incentive effect of environmental policy instruments when innovation is uncertain and occurs in very complex industrial subsystems. The case of end-of-life vehicles (ELVs) is considered focusing predominantly on the effects of the European Directive adopted in 2000 which stipulated economic instruments as free take-back, and on the voluntary agreements in place in many EU countries. The ELV case study is an example of a framework where policy-making faces an intrinsic dynamic and systemic environment. Coherent sequences of single innovations taking place in both upstream (car making) and downstream (car recycling/recovery) of the ELV system can give rise to different “innovation paths”, in accordance with cost-benefit considerations, technological options and capabilities associated to the different industrial actors involved. The impact of economic instruments on innovation paths, in particular free take-back, is considered. Deficiencies or difficulties concerning the transmission of incentives between different industries can prevent the creation of new recycling/recovery/reuse markets, giving rise to other less preferable and unexpected outcomes. The implication for policy is a need for an integrated policy approach, as enforceable VAs, in order to create a shared interindustry interest for innovation and to reduce the possible adverse effects which economic instruments exert on innovation through cost benefit impacts on key industrial and waste-related agents involved in the ELV management system. These advantages should be taken into account vis à vis the emergence of Integrated Product Policy (IPP) as a leading concept of EU environmental policy and the associated shift from "extended producer responsibility" to "extended product responsibility".ELV, Induced innovation, Dynamic efficiency, Economic instruments, Recycling

A Political Economy Approach to Resource Taxation: Weak Sustainability, Revenue Recycling and Regional Planning

We present conceptual and empirical insights on the issue of resource taxation, an intrinsic regional environmental policy. It deals with the implementation of environmental taxes and environmental planning at regional level, as tools aimed at achieving weak sustainability for non renewable resources like aggregates, extracted for a diverse set of economic aims. We frame the discussion in the spirit of refreshing the need of ecological and resource tax reforms at national and regional level-. We do note and discuss the intrinsic peculiarities of resource taxes with respect to emission taxes, namely the integration with regional planning, the use of revenue for weak sustainability objectives, the different role by played technology and efficiency. Factors that are to be taken into account in any specific implementation. We empirically investigate resource taxation issues by focusing on aggregate extraction management and policy of two large Northern Italian regions, Lombardy and Emilia-Romagna. We conclude that the possible effects of extraction charges for the aggregate market development in Italy can be very limited. The level of charges is generally too low to be expected to have an effect on demand (through aggregate prices) and supply of aggregates. The environmental objectives of planning are, at least for the moment, other than reducing extraction, and they generally consist of minimising external impacts, to support sustainable management of landscapes, and to provide multi-value public goods within the local area. The evidence shows that even more for resource taxes a political economy analysis that encompasses institutional and planning issues is needed to effectively shape environmental policies. The complementarity of land use planning and economic instruments is a key driver of sustainability performances and witness reciprocal influences. The unintended effects of economic instruments are also a crucial thing for evaluating effectiveness and efficiency. Those include positive effects of ‘institutional kind’ on the governance and organizational performance of the integrated policy-planning framework.Resource tax reforms; aggregates; environmental charges; regional planning; sustainability; ex post compensations; Political economy; unintended effects; environmental federalism

Waste Generation, Incineration and Landfill Diversion. De-coupling Trends, Socio-Economic Drivers and Policy Effectiveness in the EU

Waste generation and waste disposal are issues that are becoming increasingly prominent in the environmental arena both from a policy perspective and in the context of delinking analysis. Waste generation is still increasing proportionally with income, and economic and environmental costs associated to landfilling are also increasing. This paper provides a comprehensive analysis of waste generation, incineration, recycling and landfill dynamics based on panel data for the EU25, to assess the effects of different drivers (economic, structural, policy) and the eventual differences between western and eastern EU countries. We show that for waste generation there is still no Waste Kuznets Curve (WKC) trend, although elasticity to income drivers appear lower than in the past. Landfill and other policy effects do not seem to provide backward incentives for waste prevention. Regarding landfill and incineration, the two trends, as expected, are respectively decreasing and increasing, with policy providing a strong driver. It demonstrates the effectiveness of policy even in this early stage of policy implementation. This is essential for an ex post evaluation of existing landfill and incineration directives. Eastern countries appear to perform generally quite well, thus benefiting from their EU membership and related policies in terms of environmental performances. We may conclude that although absolute delinking is far from being achieved for waste generation, there are first positive signals in favour of an increasing relative delinking for waste generation and average robust landfill diversion, and various evidence of a significant role of the EU waste policies implemented in the late 1990s and early 2000s on landfill diversion. Waste prevention is nevertheless the next necessary target of waste regulatory efforts.Waste Kuznets Curves, Delinking, Waste Generation, Waste Disposal, Landfilling, Landfill Policies, Evaluation Methodology, Incineration

Environmental Efficiency, Emission Trends and Labour Productivity: Trade-Off or Joint Dynamics? Empirical Evidence Using NAMEA Panel Data

The paper provides new empirical evidence on the relationship between environmental efficiency and labour productivity using industry level data. We first provide a critical and extensive discussion around the interconnected issues of environmental efficiency and performance, firm performances and labour productivity, and environmental and non-environmental innovation dynamics. The most recent literature dealing with environmental innovation, environmental regulations and economic performances is taken as reference. We then test a newly adapted EKC hypothesis, by verifying the correlation between the two trends of environmental efficiency (productivity, namely sector emission on added value) and labour productivity (added value on employees) over a dynamic path. We exploit official NAMEA data sources for Italy over 1990-2002 for 29 sectoral branches. The period is crucial since environmental issues and then environmental policies came into the arena, and a restructuring of the economy occurred. It is thus interesting to assess the extent to which capital investments for the economy as a whole are associated with a positive or negative correlation between environmental efficiency of productive branches and labour productivity, often claimed by mainstream theory dealing with innovation in environmental economics. We believe that on the basis of the theoretical and empirical analyses focusing on innovation paths, firm performances and environmental externalities, there are good reasons to expect a positive correlation between environmental and labour productivities, or in alternative terms a negative correlation between mission intensity of production and labour productivity. The tested hypothesis is crucial within the long standing discussion over the potential trade-off or complementarity between environmental and labour productivity, strictly associated with sectoral and national technological innovation paths. The main added value of the paper is the analysis of the aforementioned hypothesis by exploiting a panel data set based on official NAMEA sectoral disaggregated accounting data, providing both cross section heterogeneity and a sufficient time span. We find that for most emissions, if not all, a negative correlation emerges between labour productivity and environmental productivity. Though this trend appears driven by the macro sectors services, manufacturing and industry, this evidence is not homogenous across emissions. In some cases U-shapes arise, mainly for services, and the assessment of Turning Points is crucial. Manufacturing and industry, all in all, seem to have a stronger weight. Overall, then, labour productivity dynamics seem to be complementary to a decreasing emission intensity of productive processes. The extent to which this evidence derives from endogenous market forces, industrial restructuring and/or from policy effects is scope for further research. The relative role of manufacturing and services in explaining this pattern is also to be analysed in future empirical analyses. In addition, the role of capital stocks and trade openness are extensions which may add value to future analyses carried out on the same NAMEA dataset.Decoupling, NAMEA Emissions, Labour Productivity, Sectoral Added Value, Kuznets Curves, Environmental Efficiency

Economic Dynamics, Emission Trends and the EKC Hypothesis New Evidence Using NAMEA and Provincial Panel Data for Italy

This paper provides new empirical evidence on delinking trends concerning emission-related indicators in Italy. We discuss methodological issues regarding the analysis of delinking and examine the related Environmental Kuznets Curves (EKC) literature to explore and assess the most value added research lines after more than a decade of intensive research in the field. The main contribution of the paper is in providing EKC evidence exploiting environmental-economic merged panel datasets at a decentralized level exploiting long time series and rich cross section heterogeneity at both sectoral and provincial level. This crucially augments the unsatisfactory outcomes deriving from cross country analyses, which are less informative for policy purposes since they provide averages for environmental-economic relationships. Two panel datasets: 1990-2000 emissions at province level; and sectoral disaggregated NAMEA emissions sources for 1990-2001 are analyzed. We find mixed evidence supporting the EKC hypothesis. Some of the pollutants in the NAMEA data, such as CO2, CH4 and CO, produce inverted-U shaped curves with coherent within range turning points. Other emission trends for the period under consideration show monotonic or even N shaped (SOX, NOX, PM10) relationship. Other emissions show relatively less robust results, with mixed evidence arising from different specifications. This partially confirms some of the criticisms directed to EKC empirical investigations. However, our analysis shows that probably there is no single EKC dynamic, but rather many EKC dynamics, differing depending on (i) period of observation; (ii) country/area; (iii) emissions/environmental pressures; (iv) sectors. Sectoral disaggregated analysis highlights that an aggregated outcome should hide some heterogeneity across different sectors. Services tend to present an inverted-N shape in most cases. Manufacturing industry shows a mix of EKC inverted- U and N shapes, depending on the emission considered. The same is true for industry (all industries, not only manufacturing): though a turning point has been experienced, N shapes may lead to increased emissions with respect to very high levels of the income driver. The analysis of provincial data shows that inverted-U shaped curves are present for some of the emissions in the SINAnet- APAT database, such as CH4, NMVOC, CO and PM10, with coherent within range turning points. Other emission trends show a monotonic relationship (CO2 and N2O), or in some cases an inverted-N shaped relationship (SOX and NOX). This kind of analysis at macro sector and/or specific sector level appear to be the most promising and robust field of future research for the assessment of EKC dynamics. National studies grounded in geographical heterogeneity, rather than regional/international analysis, and focused on sectoral trends, are more informative for policy making. The implementation of such investigations needs larger datasets than are currently available. We thus point to the need for increasing and continual effort on constructing integrated environmental/economic statistical accounts.Decoupling, NAMEA Emissions, Economic Drivers, Kuznets Curve, Environmental Efficiency

Municipal Waste Production, Economic Drivers, and ‘New’ Waste Policies: EKC Evidence from Italian Regional and Provincial Panel Data

This paper provides empirical evidence on delinking and Environmental Kuznets Curve (EKC) for municipal waste production in Italy. First, methodological issues and literature on delinking and EKC for waste are critically re-examined. Secondly, we analyse two very disaggregated panel datasets on Italian Regions and Provinces (1996-2004 data for the 20 regions, 2000-2004 data for the 103 provinces) to estimate the extent to which delinking between waste production and economic drivers is taking place. The empirical analysis of different specifications shows mixed evidence in favour of an EKC relationship. Evidence supporting an EKC hypothesis significantly arises at a provincial level, which presents a very high data heterogeneity. Nevertheless, the turning point is at very high levels of added value per capita (around 23,000-26,000€), which characterise a very limited number of wealthy (Northern) Italian provinces. The analysis does not reveal a similar evidence for the regional dataset: only a relative delinking dynamic emerges at the provincial level, we also note a positive relationship between waste production and the share of separated waste collection, which can be explained by the sharp difference in income and waste-policy performance between Northern and Southern Italy. Population density is not significant. Finally, the test on some policy proxies, i.e. the diffusion of the new waste tariff regime at the local-level and the ability of utilities to recover waste service cost, leads to the conclusion that they are not (yet) impacting waste production. To lower the turning points and to avoid an increasing gap between geographical areas, innovative (market based) and more effective policy instruments should be implemented. In particular, the weight of waste policies should be rebalanced towards waste prevention targets and instruments, in line with the priorities stated by the EU and Member Countries. In fact, the indirect feedback effect of good post-production waste management policies/practices on reducing waste production at a source can be weak and slow. In general, the results confirm that more geographically-disaggregated data may offer more insights with respect to cross-country datasets, also from the policy perspective.Decoupling, Environmental Kuznets Curves, Environmental Efficiency, Waste Indicators, Waste Policy, Economic Drivers, Panel Data

A Bayesian Approach to the Estimation of Environmental Kuznets Curves for CO2 Emissions

This paper investigates the EKC curves for CO2 emissions in a panel of 109 countries during the period 1959-2001. The length of the series makes the application of a heterogeneous estimator suitable from an econometric point of view. The results, based on the hierarchical Bayes estimator, show that different EKC dynamics are associated with the different sub samples of countries considered. On average, more industrialized countries show an EKC evidence in quadratic specifications, which are nevertheless probably evolving into an N shape, emerging from cubic specifications. Less developed countries consistently show that CO2 emissions still rise positively with income, though some signals of an EKC path arise.Environmental Kuznets Curve, CO2 Emissions, Bayesian Approach, Heterogeneous Panels

Environmentally-Oriented Innovative Strategies and Firm Performances in Services. Micro-Evidence from Italy

This paper aims at analysing the role of the environment in innovative strategies based on firm economic performance indicators such as employment, turnover, and labour productivity growth. We exploit a unique dataset of 773 Italian service firms with 20 or more employees comprising 1993-1995 CIS II data on firm innovation strategic motivations and 1995-1998 data on employment, turnover, and labour productivity from the System of the Enterprise Account (SEA). We specify a Gibrat-like empirical model in which the covariates include firm strategies (innovation and environmental), and a set of other explanatory variables and controls. Our econometric findings show a negative link between environmental motivations and growth in employment and turnover and a consequent not significant effect on labour productivity growth. The effect on employment is partly in line with past evidence and may derive from efficiency improvements (dematerialization processes) which also impact on efficiency by reducing workforce number. It is plausible that the net effect derives from the absence of low skilled employment and a creation of high skilled jobs, as a consequence of increased environmental awareness. The effect on turnover shows a negative impact from environmental innovation strategy, implying either a short-medium effect, possibly balanced in the long run by net benefits in terms of higher added value, or a real negative impact, which may be contingent on the observed period, when environmental strategies where not at the heart of strategic management policies. However, productivity-related effects (the core of performance indicators) are not significant. Mainstream hypotheses related to eventual negative impacts are thus not confirmed, although Porter-like effects and virtuous circles between environmentally strategies and performance do not seem to be present.Services, Firm Environmental Strategies, Firm Growth, CIS Survey, Innovation

The Relationship Between Environmental Efficiency and Manufacturing Firm’s Growth

This paper investigates the empirical link between emission intensity and economic growth, using a very large data set of 61,219 Italian manufacturing firms over the period 2000-2004. As a measure of lagged environmental performance (efficiency) at firm level we exploit NAMEA sector for CO2, NOx, SOx data over 1990-1999. The paper tests the extent to which (past) environmental efficiency/intensity, which is driven by structural features and firm strategic actions, including responses to policies, influences firms growth. Our results show, first, a typical trade off generally appearing for the three core environmental emissions we analyse: lower environmentally efficiency in the recent past allows higher degrees of freedom to firms and relax the constraints for growth, at least in this short/medium term scenario. Nevertheless, the size of the estimated coefficients is not large. Trade off are significant for two emission indicators out of two, but quite negligible in terms of impacts, besides the case of CO2. For example, growth is reduced by far less than 0.1% in association to a 1% increase of environmental efficiency. Environmental efficiency does not seem a primary cost factor and constraint to growth if compared to other factors affecting firm targets and firm competitiveness. In addition, non-linearity seems to characterise the economic growth-environmental performance relationship. Signals of inverted U shape appears: this may be a signal that both firm strategies and recent policy efforts are affecting the dynamic relationship between environmental efficiency and economic productivity, turning it from an usual trade off to a possible joint complementary/co-dynamics, where bad environmental performances hamper firm growth and investments in greener technologies may be associated to positive economic performances of firms and sectors.Firm growth, Manufacturing, Emission intensity, Economic performance, Environmental performance

Resources and Technologies

This Working Paper joint two previous articles by the authors: The economic theory of exhaustible natural resources, in “Enciclopedia degli Idrocarburi”, vol. IV, Istituto della Enciclopedia Treccani, Roma, 2008, pp. 3-10;Technological innovation, relative scarcity, investments, in “Enciclopedia degli Idrocarburi”, vol. IV, Istituto della Enciclopedia Treccani, 2008, pp. 11-22. In the first one (cap. 1-4), we consider the contribution of economic theory (partly through a reevaluation of history) in order both to interpret and predict events, and to identify economic policies; this happens especially when the world economy feels the significant constraints imposed by some natural resources and raw materials, partly due to the rapid growth of a number of developing countries, and when there is an urgent need to increase resources rapidly to ensure continuing availability. Even if the problem of scarce resources (of which natural resources are the most obvious category) has been central to analysis for centuries, natural resource economics is contradictory. The main reason for this is that economic theory is out of step with prevailing economic conditions, as a consequence of the varying concern for a crucial phenomenon in the dynamics of economic systems: the opposition-coexistence of the scarcity of natural resources and the producibility of commodities. Natural resource economics can be summarized by dividing it into three main lines of thought: the theory of producibility and scarcity developed by classical economists; the theory of general and natural scarcities developed by marginalists and neoclassicals; the theory of dynamics with and without natural scarcities developed by macroeconomists, structuralists and empirical stylizers. Using this three-way subdivision, which is not clearly codified in economic theory, the basic features of each approach will be examined with special attention to its early exponents. The historical starting point is the second half of the Eighteenth century, although we will ignore contributions such as those made by the Physiocrats who, during the same period, developed a theory of production based on the surplus generated by agriculture. In the second one (cap. 5-6), we consider that the role of technological innovation for resources use and conservation is often measured by empirical indicators of intensity or efficiency which express the evolution of resource use in relation to variables such as population and GDP. The historical evolution of these indicators tends to indicate a process of decoupling – in other words, a decrease in the energy/emissions intensity of economic activity or an increase in the efficiency/productivity of resource use. These empirical regularities have led to the proposition of stylized facts representing the relationships between resource-use efficiency and economic growth known as environmental Kuznets curves. However, the economic interpretations of the innovation mechanisms underlying the progress suggested by efficiency indicators, nonetheless, remain open and complex at the very time when there is increasing demand for further substantial advances in resource-use efficiency. We will survey the empirical evidence on the medium- and long-term dynamics of these indicators and will discuss their significance. This will be followed by an analysis of the possible role played by economic factors (especially resource prices and markets) and institutional factors (especially climate policy) in triggering and supporting progress in the use efficiency of energy resources.natural resources; technological innovation; relative scarcity; investments
