Do Eco-Innovations Harm Productivity Growth through Crowding Out? Results of an Extended CDM Model for Italy

This paper discusses the results for Italy of a CDM model (Crepon et al, 1998) further extended with the objective of evaluating drivers and productivity effects of environmental innovations. The particular nature of environmental innovations, especially as regards the need of government intervention to create market opportunities, is likely to affect the way through which they are pursued (innovation equation within the CDM model) and their effect on productivity (productivity equation). Here I test two main hypothesis: (i) to what extent polluting firms rely on own innovations to improve their environmental performance? (ii) do the pursue of environmental innovations reduce the likelihood of obtaining other profitable innovations (crowding out)? Results, based on administrative data (AIDA by Bureau van Dijk and patent data from PATSTAT) show that innovation efforts of polluting firms and sectors is significantly biased towards environmental innovations and that environmental innovations tend to crowd out other more profitable (at least in the short run) innovations

Sector CO2 and SOx emissions efficiency and investment: homogeneous vs heterogeneous estimates using the Italian NAMEA

The relationships between emissions ad economic drivers differ substantially both across countries and across sectors. In this paper I investigate cross-sector heterogeneity of emissions (CO2 and SOx) / investments relationships of Italian branches for the period 1990-2006 by using the Italian NAMEA (National Accounting Matrix including Environmental Accounts). The ‘environmental’ direction of investments in different types of capital goods is crucial in the prediction of future patterns of environmental efficiency due to the persistence of the choices regarding the features of the capital stock. Within this relationship, the role of variations in prices of energy fuels and in environmental taxes is considered to identify relevance and the direction of the technical changes induced by prices and taxes. I compare homogeneous estimates (FE) with heterogeneous estimates (SUR): homogeneity of slopes across branches is always rejected (aggregation bias). Furthermore, results differ substantially between CO2 and SOx, due to different environmental and economic features of the two types of emissions. Results show a relevant role of economic forces (investments) in explaining CO2 dynamics while SOx trends are determined to higher extent by exogenous events. The potential role of ICTs in promoting more environmental efficient production processes has not been exploited yet by Italian manufacturing sectors.NAMEA; SUR; eco-innovation; emissions efficiency

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

Emissions Trends and Labour Productivity Dynamics Sector Analyses of De-coupling/Recoupling on a 1990-2005 Namea

This paper provides new empirical evidence on Environmental Kuznets Curves (EKC) for greenhouse gases (GHGs) and air pollutants at sector level. A panel dataset based on the Italian NAMEA over 1990-2005 is analysed, focusing on both emission 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. CH4 is moderately decreasing in recent years, but being a minor gas compared to CO2, the overall performance on GHGs is not compliant with Kyoto targets, which do not appear to have generated a structural break in the dynamics at least for GHGs. SOx and NOx show decreasing patterns, though the shape is affected by some outlier sectors with regard to joint emission-productivity dynamics, and for SOx exogenous innovation and policy related factors may be the main driving force behind observed reductions. Services tend to present stronger delinking patterns across emissions. Trade expansion validates the pollution haven in some cases, but also show negative signs when only EU15 trade is considered: this may due to technology spillovers and a positive ‘race to the top’ rather than the bottom among EU15 trade partners (Italy and Germany as the main exporters and trade partner in the EU). Finally, general R&D expenditure show weak correlation with emissions efficiency. EKC and IPAT derived models provide similar conclusions overall; the emission-labour elasticity estimated in the latter is generally different from 1, suggesting that in most cases, and for both services and industry, a scenario characterised by emissions saving technological dynamics. Further research should be directed towards deeper investigation of trade relationship at sector level, increased research into and efforts to produce specific sectoral data on ‘environmental innovations’, and to verifying the value of heterogeneous panel models capturing sector heterogeneity.Greenhouse Gases, Air Pollutants, NAMEA, Trade Openness, Labour Productivity, EKC, STIRPAT, Delinking

Linking NAMEA and Input output for 'consumption vs. production perspective' analyses

We 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 a production and consumption perspective 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 aggregation in the analyses (e.g. 16, 32, 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 both for the consumption and the production 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.NAMEA; extended input output; sustainable consumption and production; aggregation bias; final demand

The impact of energy prices on employment and environmental performance : Evidence from french manufacturing establishments

This paper evaluates the historical influence of energy prices on a series of measures of environmental and economic performance for a panel of French manufacturing establishments over the period 1997-2010. The focus on energy prices is motivated by the fact that changes in environmental and energy policies have been dominated by substantial reductions in discounts for large consumers, making the evaluation of each policy in isolation exceedingly difficult. To identify price effects, we construct a shift-share instrument that captures only the exogenous variation in establishmentspecific energy prices. Our results highlight a trade-off between environmental and economic goals: although a 10 percent increase in energy prices brings about a 6 percent reduction in energy consumption and to a 11 percent reduction in CO2 emissions, such an increase also has a modestly negative impact on employment (-2.6 percent) and very small impact on wages and productivity. The negative employment effects are mostly concentrated in energyintensive and trade-exposed sectors. Simulating the effect of a carbon tax, we show that job losses for the most exposed sectors can be quite large. However, these effects are upper bounds and we show that they are significantly mitigated in multi-plant firms by labor reallocation across establishments

Climate policies and Skill-biased employment dynamics : evidence from EU countries

The political acceptability of climate policies is undermined by job-killing arguments, especially for the least-skilled workers. However, evidence for distributional impacts for different workers remains scant. We examine the associations between climate policies, proxied by energy prices and a stringency index, and workforce skills for 14 European countries and 15 industrial sectors over the period of 1995-2011. We find that, while the long-term decline in employment in most carbon-intensive sectors is unrelated to policy stringency, climate policies have been skill biased against manual workers and have favoured technicians and professionals. This skill bias is confirmed using a shift-share instrumental variable estimato

Finance and the Misallocation of Scientific, Engineering and Mathematical Talent

The US financial sector has become a magnet for the brightest graduates in the science, technology, engineering and mathematical fields (STEM). We provide quantitative bases for this well-known fact and illustrate its consequences for the productivity growth in other sectors over the period 1980-2014. First, we find that the share of STEM talents grew significantly faster in finance than in other key STEM sectors such as high-tech, and this divergent pattern has been more evident for STEM than for general skills and more pronounced for investment banking. Second, this trend did not reverse after the Great Recession, and a persistent wage premium is found for STEM graduates working in finance and especially in typical financial jobs at the top of the wage distribution. Third, the brain drain of STEM talents into finance has been associated with a cumulative loss of labor productivity growth of 6.6% in the manufacturing sectors. Our results suggest that increasing the number of STEM graduates may not be enough to reignite sluggish economic growth without making their employment in finance more costly

SMEs and barriers to eco-innovation in EU: A diverse palette of greens

Ingenio Working Paper SeriesEco-innovation is an explicit aim of major EU policy strategies. Many environmental policy de facto require firms to eco-innovate to comply with policy requirements, while the overlap between policy-driven and market-driven eco-innovation strategies is increasingly important for many firms. Barriers to eco-innovation can then emerge as a critical factor in either preventing or stimulating EU strategies, policy implementation, and 'green strategies' by firms. In this paper, we propose a taxonomy of EU SMEs in terms of barriers to eco-innovation. The aim is to discriminate among SMEs on how they differ in terms of perception of barriers and engagement in environmental innovation, thus highlighting the need to look at eco-innovation barriers in relation to firms' attitudes, technological and organizational capabilities, and strategies. We identify six clusters of SMEs. These clusters include firms facing 'Revealed barriers', 'Deterring barriers', 'Cost deterred' firms, 'Market deterred' firms, 'Non eco-innovators' and 'Green champions'. The clusters show substantial differences in terms of ecoinnovation adoption. We show that our proposed taxonomy has little overlap with sector classifications. This diversity should be taken into account for successful environmental innovation policies.Peer reviewe
