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.Giovanni Maringiovanni.marin@alumni.imtlucca.itMassimiliano Mazzanti2012-03-26T11:14:18Z2012-07-05T10:08:53Zhttp://eprints.imtlucca.it/id/eprint/1241This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/12412012-03-26T11:14:18ZThe evolution of environmental and labor productivity dynamicsThis paper provides new empirical evidence on delinking in income–environment dynamic relationships for CO 2 and air pollutants at the sector level. A panel dataset based on the Italian NAMEA (National Accounting Matrix including Environmental Accounts) over 1990–2007 is analyzed, focusing on both emissions efficiency (EKC model) and total emissions (IPAT model). Results show that, looking at sector evidence, both decoupling and also eventually re-coupling trends could emerge along the path of economic development. The overall performance on greenhouse gases, here CO 2 , is not compliant with Kyoto targets. SOx and NOx show decreasing patterns, though the shape is affected by some outlier sectors with regard to joint emission-productivity dynamics. Services tend to present stronger delinking patterns across emissions than manufacturing. Trade expansion validates the pollution haven in some cases, but also shows negative signs when only EU 15 trade is considered. This may due to technology spillovers and a positive ‘race to the top’ rather than the bottom among EU 15 trade partners. General R&D expenditure shows weak correlation with emissions efficiency. SUR estimators (Seemingly Unrelated Regressions) suggest that, as regards manufacturing, the slope varies across sectors. Further research should be directed towards deeper investigation of trade relationship at the sector level and increased research into and efforts to produce specific sectoral data on ‘environmental innovations’.Giovanni Maringiovanni.marin@alumni.imtlucca.itMassimiliano Mazzanti2012-03-26T10:42:48Z2012-07-05T10:09:12Zhttp://eprints.imtlucca.it/id/eprint/1240This item is in the repository with the URL: http://eprints.imtlucca.it/id/eprint/12402012-03-26T10:42:48ZLinking NAMEA and Input output for "consumption vs. production perspective" analyses: Evidence on emission efficiency and aggregation biases using the Italian and Spanish environmental accountsWe integrate input output and NAMEA tables for Spain and Italy in 1995, 2000 and 2005, in order to address the hot policy issue of sustainable consumption and production. A comparison of production and consumption perspectives may have relevant policy implications. We deal with the domestic technology assumption and primarily the aggregation bias that may result when calculating indirect emission using different sector aggregations in the analyses (e.g. 16, 30, 50). Extended Input Output Analysis provides analyses of the emissions embodied in domestic consumption and domestic production by considering the structure of intermediate inputs and environmental efficiency in each production sector. Our empirical findings show that different sectoral aggregation significantly biases the amount of emissions for the consumption perspective, though differently in the two countries. Italy surprisingly show consumption/production ratios around or lower than one, but in line with some major work at EU level. Our results thus suggest that special attention must be paid when interpreting the EE-IOA of country estimated amounts of embodied emissions, both in domestic final demand and those directly associated with the production sectors when the sectoral aggregation level has a low definition as considered in some recent similar studies.Giovanni Maringiovanni.marin@alumni.imtlucca.itMassimiliano MazzantiAnna Montini
