Agglomeration, related variety and vertical integration

Several recent studies investigate the relation between geographic concentration of production and vertical integration, based on the hypothesis that spatial agglomeration of firms in the same industry facilitates input procurement thereby reducing the degree of vertical integration. The present paper contributes to this debate by also considering the effects of industry variety at the local level. Specifically, we consider two forms of variety: unrelated variety and vertically related variety. The latter index is constructed using information drawn from input-output tables and captures the opportunities for outsourcing within the local system. We consider inter-industry vertical integration by taking account of the ownership of activities with input-output linkages. Using a dataset of 24,663 Italian business groups in 2001, we estimate Tobit models to investigate the influence of vertically related variety and other agglomeration forces on the degree of vertical integration of groups. Our evidence confirms that vertical integration is influenced by industry specialization at the local level. We also find that the higher the vertically related variety, the lower the need for firms to integrate activities since they have more opportunities to acquire intermediate goods and services within the local system.vertical integration, agglomeration, related-variety, business group

Business groups and the boundaries of the firm

This paper aims to show that the business group – i.e. the set of firms under common ownership and control – is the most appropriate unit to study the behavior and organization of firms and define their boundaries. Particular emphasis is given to notions such as unitary direction – i.e. the influence over strategic decisions – and administrative co-ordination which allow owners to exercise supervision and authority over the controlled companies.business group; boundary of the firm; unitary direction

International linkages, local externalities, innovation and productivity. A structural model of Italian manufacturing firms

Using a large sample of Italian manufacturing firms, in this paper we estimate a structural model of research, innovation, productivity and export performance augmented to take account for the role played by local externalities. This model, which is an "enlarged" version of Crepon, Duguet and Mairesse (1998) model, comprises four main equations. The first identifies the factors underlying the intensity of Research and Development (R&D) investments; the second links R&D capital to innovation output; the third focuses on Total Factor Productivity (TFP) as determined by innovation; the fourth relates export performance to TFP. Our estimates show the significant role played by local externalities in these processes. In particular, related variety and urbanization positively affect the creation of new ideas through R&D, while specialization impacts on TFP to complement innovation output. Finally, urbanization economies support TFP in driving firms' export performance.export, innovation, productivity, R&D, spatial agglomeration

Environmental Innovations, Local Networks and Internationalization

This paper investigates the drivers of the environmental innovations (EI) introduced by firms in local production systems (LPS). The role of firm network relationships, agglomeration economies and internationalization strategies is analysed for a sample of 555 firms in the Emilia-Romagna region, North-East of Italy. Cooperating with ‘qualified’ local actors – i.e. universities and suppliers – is the most important driver of EI for most firms, along with their training policies and IT innovations. The role of agglomeration economies is less clear and seems to depend on the EI propensity of more locally oriented firms playing in district areas, which might even turn agglomeration into dis-economies. Networking effects and agglomeration economies are instead found to strongly promote the adoption of EI by multinational firms, thus highlighting the importance of local-global interactions. We provide some interesting findings for particular kinds of challenging EI in fields as CO2 abatement and ISO labelling, generally extending the analysis EI driver by joining local and international factors.Eco-Innovation, Foreign Ownership, Networking, District, Agglomeration Economics, Local Production Systems

The European Emission Trading Scheme and environmental innovation diffusion: Empirical analyses using Italian CIS data

We study the driving forces behind the adoption of environmental innovations (EI) in the Italian economy over 2006-2008 through empirical analyses of the new wave of Community Innovation Survey (CIS) data that covered environmental innovation adoptions in different realms (energy, carbon, production, consumption, etc..). Given the shortage of studies that have empirically assessed the innovation effects of ETS at micro econometric level, we investigate whether the first phase of EU ETS (started in 2005-2006) has exerted some effects on environmental innovations. We then include in a typical probit innovation function some policy stringency indicators, for the ETS sectors, to verify whether the likelihood of adopting environmental innovations is stimulated among other factors by the ETS lever. We test a wide and comprehensive set of potential drivers, including internal factors (R&D), external (to the firm) factors (cooperation, networking), international drivers (foreign related relationships), and mostly important, the dynamic incentives to innovation eventually provided by the ETS implementation. Estimates show that external forces and complementarity with other management practices are particularly relevant to increase the adoption of relatively new and radical technologies: relationships with other firms and institutions, local public funding, group membership are the key factors in this sense. Training is also positively related to EI, confirming recent evidence. The role of ETS on EI seems instead to be weak, but it turns out to be significant for energy efficiency innovations and for consumption level/good related reductions of atmospheric and water emissions.environmental innovation; industrial sectors; ETS; innovation drivers; CIS data

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

Social Capital, R&D and Industrial Districts

The main idea behind this paper is that social capital is not, as generally suggested by the socio-economic literature, an individual attitude towards something which does not imply privately appropriable economic benefits. Actually, SC might and should be interpreted as a public component of an investment which implies private and public benefits entangled with each other. In order to put forward this idea, a dynamic theoretical model that assumes social capital as the public component of the impure public good R&D is developed. It shows that the ‘civic culture’ of the district area in which the firm works is not sufficient as an incentive to increase its investment in social capital, because this investment strictly depends on the economic convenience of investing in the impure public good. Social capital /networking dynamics might positively and complementarily evolve only if the opportunity cost of investing in innovation is sufficiently low. We consequently focus our attention on a specialized industrial district located in the Emilia Romagna region – the biomedical district of Mirandola (Modena) – characterised by a strong pattern of innovative activity. Using a proxy for innovative activity as dependant variable, we observe that R&D and networking/social capital arise as complementary driving forces for innovation outputs. When empirical evidence confirms that this complementarity plays a key role, and consequently strong links exist between market and non-market dynamics relating to firms, the role for policy actions targeted to social capital is larger. The policy effort should be targeted toward both market and non-market characteristics taken together, rather than solely to the production of (local) public goods (social capital) or innovation inputs as independent elements of firm processes. The input of SC alone is not sufficient to ensure innovation and growth: economic incentives matter. On the other hand, whenever SC dynamics are crucial for R&D private investments, the effect of economic incentives depends on the presence and degree of their complementarity.Social capital, R&D, Technological innovation, Industrial districts

Brown Sunsets and Green Dawns in the Industrial Sector: Environmental Innovations, Firm Behavior and the European Emission Trading

We study the driving forces behind the adoption of environmental innovations (EI) in the Italian industry over 2006-2008 through analyses of the new wave of Community Innovation Survey (CIS) data that covered for the first time environmental innovation adoptions. We investigate whether the first phase of EU ETS has exerted some effects on environmental innovations by using a very large sample of italian manufcturing firms. Estimates show that external forces and complementarity with other management practices are particularly relevant to increase the adoption of relatively new and radical technologies: relationships with other firms and institutions, local public funding, group membership are the key factors. The role of ETS on EI seems instead to be weak: it drives innovation if we compare ETS and non ETS firms, but the stringency itself does not matter, due to sector idiosyncratic factors and to the fact that stability of policy also matters.Environmental Innovation, Industrial Sectors, ETS, Innovation Drivers, CIS Data

Spatial Agglomeration, Technology and Outsourcing of Knowledge Intensive Business Services Empirical Insights from Italy

Aim of this paper is to explore the main drivers of outsourcing of knowledge intensive business services by Italian manufacturing firms. While anecdotal and empirical evidence has emphasized labour cost and scale economies as behind firms’ choices to outsource production or service activities, here we focus on spatial agglomeration and technology as important factors. Using microeconomic data on a repeated cross-section of Italian manufacturing firms for the period 1998-2003, we develop a two-stage model in order to avoid selection bias: first, we estimate the determinants of the firm's decision to outsource business-related services; second, we estimate the main factors underlying the intensity and complexity of KIBS outsourcing, expressed by the number of service activities that are externalized. Our results show that labour cost-savings are not relevant in driving the decision to outsource KIBS, but ICT, R&D and location within a dense and technologically developed industrial district have very positive effects.KIBS, Service Outsourcing, R&D, ICT, Spatial Agglomeration

Agglomeration, related-variety and internationalisation. Does a relationship exist?

This paper uses a large sample of Italian manufacturing firms over the period 2004-2006, to investigate whether different types of agglomeration externalities affect firms’ internationalisation modes. In addition to specialisation economies, Jacobs externalities are analysed following the recent contribution by FRENKEN et al. (2007) which distinguishes between related and unrelated variety. Econometric results show that agglomeration externalities – in particular, specialisation and related-variety – positively affect export, while they do not affect the multinational strategy. Moreover, results show that the impact of agglomeration externalities on firms’ internationalisation decisions is higher for small sized firms.Agglomeration, externalities, internationalisation
