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

The dynamics of delinking in industrial emissions: The role of productivity, trade and R&D

This paper provides new empirical evidence on delinking / Environmental Kuznets Curves (EKC) for greenhouse gases and other air pollutant emissions in Italy. We analysed a panel dataset based on the Italian NAMEA for 1990-2005 with a specific focus on industry. We integrated the emission-income NAMEA with data on trade openness and R&D expenditures. The highly disaggregated dataset provides a large heterogeneity and can help to overcome the shortcomings of the usual approach to EKC based on cross-country data. We use in this paper CO2, SOx, NOx and PM10 as objects of investigation. We use as empirical models of reference both a standard EKC model and a STIRPAT/IPAT model. Our results show that looking at sector evidence, both decupling and then eventually re-coupling trends could emerge along the path of economic development. The analysis of how stagnation periods affect environmental performances is also of interest.NAMEA, trade openness, labour productivity, EKC, STIRPAT

SME Performance, Innovation and Networking Evidence on Complementarities for a Local Economic System

The paper addresses the relevancy of networking activities and R&D as main drivers of productivity performance and ouput innovation, for small and medium enterprises (SME) playing in a local economic system. Given the intangible nature of many techno organisational innovation and networking strategies, original recent survey data for manufacturing and services are exploited. The aim is to provide new evidence on the complementarity relationships concerning different networking activities and R&D in a local SME oriented system in Northern Italy. We first introduce a methodological framework to empirically test complementarity among R&D and networking, in a discrete setting. Secondly, we consequently present empirical evidence on productivity drivers and on complementarity between R&D and networking strategies, with respect to firm productivity and process/product output innovation. R&D is a main driver of innovation and productivity, even without networking. This may signify, in association with the evidence on complementarity, that firm expenditures on R&D are a primary driver for performance. The complementarity with networking is a consequential step. Networking by itself cannot thus play a role in stimulating productivity and innovation. It can be a complementary factor in situations where cooperation and networking are needed to achieve economies of scale and/or to merge and integrate diverse skills, technologies and competencies. This is compatible with a framework where networking is the public good part of an impure public good wherein R&D plays the part of the private-led driving force towards structural break from the business as usual scenario. Managers and policy makers should be aware that in order to exploit asset complementarity, possibly transformed into competitive advantages, both R&D and networking are to be sustained and favoured. our evidence suggests that R&D may be a single main driver of performance. Since R&D expenditures are associated with firm size, a policy sustain is to be directed towards firm enlargement. After a certain threshold firms have the force to increase expenditures. The size effect is nevertheless non monotonous. Then, but not least important, for the majority of firms still remaining under a critical size threshold, policy incentives should be directed to R&D in connection with networking, through which a virtuous circle may arise. It is worth noting that it is not networking as such the main engine. Networking elements are crucially linked to innovation dynamics; it is nevertheless innovation that explains and drives networking, and not the often claimed mere existence of local spillovers or of a civic associative culture in the territory. Such public good factors exist but are likely to evolve with and be sustained by firm innovative dynamics.Firm Competitiveness, Innovation, R&D, Networking, Complementarity, Local Economic System

Embedding the drivers of emission efficiency at regional level Analyses of NAMEA data

This paper provides new empirical evidence on regional-national disparities in environmental efficiency, based on analyses of NAMEA data referring to Italy and the Lazio region, where Rome is the main city. Shift-share analyses provide evidence on the drivers of environmental efficiency and on sector specificity. This confirms the usefulness of this method, in order to investigate structural and efficiency factors at the level of within country environmental efficiency performance. Our evidence shows that although the region around Rome has achieved higher environmental performance compared to Italy mainly thank to its being less industry based, some critical points in the energy sector and in some services should be taken into account in shaping the future development of the region. In addition, the use of regional NAMEA for econometric investigations of emission efficiency drivers at national level shows that though north south disparities favour northern and richer regions, in accordance with development oriented dynamics, environmental hot spots driven by specialization and efficiency related issues also appear in some northern industrial regions. Further, the role of public ad private R&D is of main relevance in enhancing emission on economic value ratios.

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

Income and time related effects in EKC

This paper documents the structural differences between climate change leading `actors' as Northern EU countries, and `lagging actors' - southern EU countries and the `Umbrella group' - with regard to their long run carbon-income relationships. We show that such categorization gives relevant policy and methodological insights. We investigate the issue of cross-country heterogeneity and the heterogeneity biases associated to standard panel data estimates but also disentangle time related and income effects. Parametric and semi parametric panel models allowing for time invariant unobserved heterogeneity robustly show that the groups of countries that were in the `Kyoto arena' less in favour of stringent climate policy, have yet to experience a turning point. Northern EU instead shows bell shapes. The key result is however obtained by estimating a semi-parametric random growth model. Country specific time related factors - that may represent latent innovation and policy features of countries - have been relatively more relevant than income effects in explaining the occurrence of such Kuznets curves. Overall, the countries differ more on their carbon-time relation than on the carbon-income relation which is in almost all cases monotonic positive. Just a few Nordic countries show a bell curve in both income and time related factors.Carbon Kuznets Curves; heterogeneous panels; semi parametric models; random growth; income effect; time related effect

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

Regional and Sector Environmental Efficiency Empirical Evidence from Structural Shift-share Analysis of NAMEA data

This paper provides new empirical evidence on regional–national disparities in environmental efficiency, based on case studies of Italy and the Lazio region, which includes the city of Rome. Shift-share analyses provide evidence on the drivers of environmental efficiency and on sector specificity. This confirms the usefulness of this method for studying the environmental economics realm, in order to investigate structural and efficiency factors at the level of within country environmental efficiency performance, even in light of the different shares of services. Our evidence shows that although the Rome region has achieved higher environmental performance compared to Italy mainly thanks to its being less industry based, some critical points in the energy sector and in some services should be taken into account in shaping the future development of the region. Environmental, industrial and sector-oriented policy making may also derive valuable information from the evidence provided by our study.NAMEA, Shift Share, Regional Development, RAMEA, Emission Efficiency, Economic Efficiency

Carbon Abatement Leaders and Laggards Non Parametric Analyses of Policy Oriented Kuznets Curves

We study the eventual structural differences of climate change leading ‘actors’ such as Northern EU countries, and ‘lagging actors’ - southern EU countries and the ‘Umbrella group’ - with regard to long run (1960-2001) carbon-income relationships. Parametric and semi parametric panel models show that the groups of countries that were in the Kyoto arena less in favour of stringent climate policy, have yet to experience a turning point, though they at least show relative delinking in their monotonic carbon-income relationship. Northern EU instead robustly shows bell shapes across models, which seem to depend on time related (policy) events. Time related effects are more relevant than income effects in explaining the occurrence of robust Kuznets curves. The reaction of northern EU to exogenous policy events such as the 1992 climate change convention that gave earth to the Kyoto era, and even the second oil shock that preceded it in the 80’s are among the causes of the observed structural differences.Carbon Kuznets Curves, Kyoto, Long Run Dynamics, Policy Events, Heterogeneous Panels, Cross-Section Correlation, Semi Parametric Models, Common Time Trends
