THE LIFE CYCLE ENVIRONMENTAL IMPACTS OF CONSUMPTION

This paper reviews assessments of environmental impacts arising from consumption, taking into account the production and disposal of goods consumed. Assessments have mostly focused on understanding household consumption, but there is an increasing interest in understanding government consumption, as well as in the treatment of gross capital formation and trade. National economic and environmental accounts are the most frequently used data source for such studies and input–output techniques are usually applied. For many OECD countries and a few developing countries, assessments address only energy or greenhouse gas emissions. Few studies address a broader range of emissions-related environmental impacts. There is a lack of consideration for important pressures on ecosystems such as habitat change and overexploitation of fisheries and forests. In all countries, housing and food are important. In poor countries, public services can contribute substantially, while in rich countries, mobility and the consumption of manufactured goods is important. In rapidly developing economies, investments, especially in infrastructure and buildings, are important causes of environmental pressure as well. Differences in production conditions and pollution intensities across countries are substantial, so explicitly modelling the production of internationally traded goods using multi-regional input–output analysis is necessary to account correctly for the environmental impacts arising from the consumption of imported goods.     

CARBON EMISSION ACCOUNTING IN MRIO MODELS: THE TERRITORY VS. THE RESIDENCE PRINCIPLE

Consumption-based CO₂ emissions, which are commonly calculated by means of environmentally extended input–output analysis, are gaining wider recognition as a way to complement territorial emission inventories. Although their use has increased significantly in the last years, insufficient attention has been paid to the methodological soundness of the underlying environmental extension. This should follow the internationally agreed accounting rules of the System of Environmental-Economic Accounting, which addresses the activities undertaken by the residents of a country, independent from where these take place. Nonetheless, some footprint calculations use extensions that account for all the activities within the territory, which leads to methodological inconsistencies. Thus, this article introduces the most relevant conceptual differences between these accounting frameworks and shows the magnitude of the gap between them building on the data generated for the EXIOBASE model. It concludes that the differences are high for many countries and their magnitude is increasing over time.     

An industrial ecology virtual framework for policy making in China

ABSTRACT

This study develops a multi-regional input–output (MRIO) laboratory for policy-relevant applications in China. The Chinese IELab features unique flexibility and advances the previous state of the art in terms of three novel aspects. First, it can generate regionally and sectorally very detailed MRIO tables based on users’ own research questions. Second, it covers the entire territorial economic boundary and has the longest and most up to date annual time series from 1978 to 2015. Third, it can be used to provide insight to a wide range of research and policy questions including social, economic, and environmental issues, thus significantly improving all applications that rely on input–output tables. These features are illustrated by generating a Beijing–Tianjin–Hebei multi-regional supply and use table for 2014 at city level and applying it to the case study of transferring Beijing’s non-capital functions according to The Beijing-Tianjin-Hebei Coordinated Development Strategy set by the Chinese government.     

Environmental responsibility and policy in a two-country dynamic input–output model

Increased spatial dependency of economic activities, as well as spatial differentiation of production and consumption, has implications for environmental policy. One of the issues that has gained importance is the responsibility for the emissions from products that cross national boundaries during the environmental policy's lifetime. This paper discusses the different ethical views of environmental responsibility. Furthermore, the policy measures that are associated with the different viewpoints are analyzed in a novel dynamic two-country two-sector dynamic input–output model. A numerical example is modeled to assess taxing schemes that are based on these ethical viewpoints. The results show that a tax on the ‘embodied’ environmental pressure, which is generally viewed as ethically preferable, is less effective that the current policy of taxing consumers of products. Our discussion however shows that these results are very dependent on the model structure and initial parameters that are used. Nevertheless, the model illustrates that policies that are based on ethically superior standpoints may have detrimental distortionary effects in the dynamic setting.     

Drivers of change in the European youth employment: a comparative structural decomposition analysis

This paper uses a structural decomposition approach to examine the proximate causes of change in the EU15 youth workforce from 1995 to 2011. Besides the traditional sources considered by the literature, I include age-specific factors: a labor utilization index that accounts for the hours that employed youth work by showing the extent of part-time contracts; an age mix factor that indicates the share that youth comprise of total employment and, finally, changes in the inverse of the overall sectoral labor productivity, which describes variations in total labor demand. By applying this approach, I identify the core drivers behind the recent changes in the evolution of youth employment in each of the 15 countries; this is crucial for tailoring policy strategies. Results suggest that to foster youth employment, most Mediterranean countries should implement youth-specific measures while other EU15 countries could do so by enhancing overall employment.     

The integration of international financial markets: an attempt to quantify contagion in an input–output-type analysis

ABSTRACT

The increasing integration of international financial markets means that credit defaults in one country have to be covered by creditors in other countries. If the principle of creditor liability were applied systematically, the financial losses incurred by the financial institution that provided the credit and is thus directly affected by the default would be ‘passed on’ through its domestic and foreign shareholders and debt holders, as well as their creditors, to the original savers. In this paper, this contagion effect will be estimated by taking international capital linkages into account. Analogously to an input–output analysis of inter-industry linkages, savings used for investments in one country are traced back to the countries from which the funds originated. This also reveals the important role of international financial centers, which essentially serve as distributors of investment risks, while the financial losses are ultimately borne by larger countries with higher levels of savings.     

Proposal for the Use of the Input–Output Approach in the Analysis of the Structure of Interdisciplinary Relationships

There exists a close similarity between the input–output structure of a national economy and the structure of the system of scientific knowledge. The flow of commodities between the different disciplines is analogous to the flow of goods and services between industries. The so-called citation indexes listing the subjects of articles published in different scientific journals and references made in them to articles published in other journals can be used to construct input–output tables describing the interrelationship between the creation and use of different scientific ideas.     

The opportunity costs of commuting: the value of a commuting satellite account framework with an example from Lisbon Metropolitan Area*

Commuting affects regional and urban economies. It shapes urban areas, defines their relationships with neighboring regions, intensifies economic flows and exacerbates energy consumption and greenhouse gas emissions. This paper sets out a proposal for an innovative commuting satellite account (CSA), integrated in a multi-regional input–output model. This framework combines commuting activities with regional distribution of income, distinct household consumption structures, real estate renting activities and the energy consumption and environmental flows incorporated in the different industries. To assess the opportunity costs of commuting, the CSA framework is applied to the Lisbon Metropolitan Area. The socio-economic-environmental impacts of a scenario in which commuters become non-commuters by moving their residence to the municipality in which they work are estimated. The analysis indicates that: commuting, in general, induces significant economic and environmental opportunity costs. Finally, the adoption of policy-oriented recommendations contributing to limit sprawling in metropolitan regions is discussed.     

Is the emperor wearing new clothes? A social assessment of the European Union 2007–2013 financial framework

ABSTRACT

Over the years, European leaders have proudly waved a social flag as one of the European Union’s (EU) constituent and differentiating elements. This commitment is assessed here through the social footprint of the European 2007–2013 multiannual financial framework among the EU countries and, worldwide, using an extended multiregional input–output model. The focus is on the quantity and the quality of income and jobs generated. We find that well-known differences among its northern, southern and eastern regions threaten the EU’s intentions for high social standards, enabling first- and second-class winners. Core EU countries account for the most of the Funds and, thus, most of the positive economic and social impacts, mainly through spillovers from peripheral regions. Beyond the EU borders, Funds expenditures induce capital compensation boosts in emerging countries not balanced by a similar labor compensation impulse. Indeed, China captures the bulk of low-skilled and temporary employment.     

Measuring industrial upgrading: applying factor analysis in a global value chain framework

ABSTRACT

A key question for promoting international competition is how to improve the position of countries and industries in global value chains (GVCs). The first step is to properly measure industrial upgrading in GVCs. This is not a trivial issue because upgrading has not been defined unambiguously. Several authors have used different (and sometimes related) measures, all of which indicate certain aspects of upgrading. Rather than trying to find the single, ultimate measure of upgrading, we propose a different approach. We examine the multidimensionality of industrial upgrading, using eight indicators in factor analysis. Four of the eight indicators adopt the GVC perspective and include, for example, the growth of the share in value-added exports. We provide three quantitative dimensions of industrial upgrading: process upgrading, product upgrading, and skill upgrading. With these dimensions, we compare and analyze the upgrading of different countries and industries using the World Input–Output Database.     

Measurement of reciprocity in a village through social networks

This paper examines measuring of interdependency among households through their transactions by using information of individual villagers in a disadvantaged area in a developing country. To obtain the information, we created a village input–output table (VIOT) from household survey data conducted in a rural village in Lao PDR in 2015 and 2016. Because each household in the village is not only a producer but also a consumer who is trading products and consuming them, the VIOT is a simple but useful tool to know the economic transactions among villagers. The main findings are that four higher-income families, which mainly trade rice very frequently, are playing key roles in the village economy, and the interdependency among higher-income households is stronger than among lower/middle-income households. Additionally, this method can be used to form an economic policy such as poverty reduction because of informing households playing a key role in the village.     

A Generalized Expression for the Commodity and the Industry Technology Models in Input–Output Analysis

Technical coefficients are usually constructed from commodity or industry technology models. Although these models are considered as competing, there is an encompassing framework that admits a clear comparison.     

The Subsystem—MFA: A Qualitative Method for Analyzing National Innovation Systems—The Case of Germany

The paper develops a method derived from the so-called minimal flow analysis (MFA), based on a subsystem approach, to find the characteristic technology flow structure of a national innovation system. The analysis uses input–output tables for Germany for the years 1980 and 1986, as well as innovation expenditure vectors, released by the Ifo-Institut, detailed for 58 sectors for the same years. The data are integrated into a subsystem approach and deliver a matrix of technology providers and technology users, which is analyzed by a suitably modified version of MFA. The results, differentiated according to rather economic vs more technical aspects, show what the German innovation system looks like and show that there was little change between 1980 and 1986.     

A New Method for the Identification of Patterns in Input–Output Matrices

This paper suggests a new algorithm for selecting the input–output (IO) coefficients of a Leontief matrix in order of importance, so providing an analytical method for decomposing an IO matrix. It avoids the choice of arbitrary thresholds for eliminating flows or coefficients, and allows for circular relationships. For this purpose, a simple inverse-important criterion has been chosen, which is consistent with the logic of the Leontief model. A procedure that greatly reduces the computational burden is then devised. This method permits new comparisons of IO structures of different countries or regions, for identifying their different degree of internal integration and their reciprocal influence through the exchange of intermediate goods. An application to an IO model for seven European Community countries for 1980 is then presented.     

New instruments – old practices? The implications of environmental management systems and extended producer responsibility for design for the environment

As the focus of environmental policy and management is shifting from cleaner production at the process level towards greener products, there is a need for new kinds of policy instruments and initiatives. Environmental management systems (EMSs) and extended producer responsibility (EPR) systems are efforts to overcome the limitations of the traditional regulatory approach. In this paper, I illustrate how EMSs and EPR systems have influenced the emergence of greener products in three case companies. These case studies are complemented by results from a survey on design for the environment in the electrical and electronics industry. Both the case studies and the survey indicate that the linkage between EMSs and product development is weak or completely missing. Therefore, the mere existence of an EMS can hardly be used as a convincing indicator of the implementation of an environmentally friendly design process. The results regarding the EPR systems are more positive. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

Structural change and female participation in recent economic growth: a multisectoral analysis for the Spanish economy

ABSTRACT

Economic growth has different impacts on gender gaps. In recent decades the growing participation of women in the labour market has reduced the gender employment gap, however a notable gender pay gap still persists standing at around 15% on average in the European Union. In this context, this paper evaluates the impact of economic growth patterns on the evolution of gender employment and pay gaps. First, sectorial feminization, direct discrimination, and structural change factors are identified and evaluated as ways to explain changes observed in the gender pay gap. Second, we explore the influence of demand, technology, and intensity factors on the evolution of employment combining gender, skill, sectorial, and temporal perspectives. As a case study, we examine Spanish economic growth from 1980 to 2007 and the influences on the size, composition (by skill), and distribution (by sector) of female and male employment, as well as the consequences for gender gaps. Our results show that structural change contributed to reduce the gender employment gap in Spain; while the evolution of the gender pay gap is less conclusive, following a sort of inverted U-shape. This paper shows the suitability and potential of the multisectorial input–output framework to analyse structural and technological changes and their impacts on the gender employment and pay gaps.     

The role of primary processing in the supply risks of critical metals

This study seeks to understand the role of primary processing, i.e. the first post-mining stage, in supply risk, by means of a case study on three critical metals (neodymium, cobalt, and platinum) in the context of Japan. Applying the ‘footprint’ concept with a multiregional input–output model, we have quantified the direct and indirect vulnerability of the Japanese economy to such risks. Considering the supply risks associated with primary processors, we find that Japanese final consumers are exposed to relatively higher supply risks for neodymium as compared with cobalt and platinum. Our study shows that the primary processing stage of a metal’s supply chain may contribute significantly to the overall supply risks, suggesting that this stage should be taken into due account in understanding and mitigating supply-chain vulnerability through, e.g. supplier diversification and alternative material development.
