the changing size distribution of u s trade unions and its description by pareto s distribution the size distribution of trade unions in the united states and changes in this distribution are documented because the most profound changes are taking place among very large unions these are subject to special analysis by invoking pareto s distribution this represents a new application of this distribution extensions to trade union wealth and to britain are broached the role of the public sector in these changes receives particular attention a simple model helps account both for the logarithmic distribution of union membership and for the contrasting experiences of public and private sector unions since the 1970s

governments as owners state owned multinational companies the globalization of state owned multinational companies somncs has become an important phenomenon in international business ib yet it has received scant attention in the literature we explain how the analysis of somncs can help advance the literature by extending our understanding of state owned firms soes and multinational companies mncs in at least two ways first we cross fertilize the ib and soes literatures in their analysis of foreign investment behavior and introduce two arguments the extraterritoriality argument which helps explain how the mnc dimension of somncs extends the soe literature and the non business internationalization argument which helps explain how the soe dimension of somncs extends the mnc literature second we analyze how the study of somncs can help develop new insights of theories of firm behavior in this respect we introduce five arguments the triple agency conflict argument in agency theory the owner risk argument in transaction costs economics the advantage and disadvantage of ownership argument in the resource based view rbv the power escape argument in resource dependence theory and the illegitimate ownership argument in neo institutional theory after our analysis we introduce the papers in the special issue that collectively reflect diverse and sophisticated research interest in the topic of somncs

does product lifetime extension increase our income at the expense of energy consumption abstract the present paper contributes to modeling a simple social accounting method with cumulative product lifetime distributions and argues how product lifetime extension affects income flow throughout the entire economic system empirical analysis focusing on automobile use ordinary passenger vehicle small passenger vehicle and light passenger vehicle in japan revealed that if all of the additional income gain from product lifetime extension flows into the investment sector a one year lifetime extension during the ten years of the study period 1990 2000 would have led to an increase in income in 2000 amounting to 7 billion yen as well as contributing to savings in energy amounting to 4 10 6 gj that is longer term passenger vehicle use increases income and decreases energy consumption under special cases we also found that in the general case when less than 93 of additional income resulting from vehicle lifetime extension is directed to the investment sector a 1 year automobile lifetime extension increases income at the expense of energy consumption

application of the structural decomposition analysis to assess the indirect energy consumption and air emission changes related to italian households consumption abstract the design of sustainable production and consumption strategies and the assessment of implemented actions require to identify the driving forces that influence the trend of energy consumption and environmental impacts for this purpose the structural decomposition analysis sda was developed as a suitable methodology to analyse the driving forces of the changes in economic energy and environmental indicators the paper presents one of the first italian studies that apply an energy and environmental extended input output model opportunely shaped to the examined context combined with sda in detail it aims at 1 investigating the energy use and the air emissions arisen from the productive sectors to meet the household final demand in the period 1999 2006 2 identifying the sources of variations in energy and environmental indicators and 3 identifying which economic sectors are the most relevant sources of variation and must to be taken into account in the definition of sustainable production and consumption strategies as sources of changes the authors investigate energy and emission intensity effects leontief effect and final demand effect outcomes point out that the increase of the final consumptions often nullifies the energy and environmental benefits due to the improvement of the eco efficiency and to the introduction of innovative technologies of production the sector level analysis shows that tertiary and electricity gas and vapour result the highest italian consuming sectors of energy thus they should be focused for energy saving strategies agriculture hunting and sylviculture and road transports that are primarily sectors affecting air emissions should be taken into account for the reduction of environmental impacts results highlight that the current dichotomy of final demand growth and improvement of eco efficiency represents a key problem that needs to be addressed therefore the presented study can aid to define suitable oriented strategies for the energy and environmental impact reduction

drivers of intersectoral metal consumption intensity in china a combined input output and sensitivity analysis abstract as a country with a high level of metal consumption china must urgently formulate effective policies to improve its metal use efficiency this article identifies the key sectors with the highest metal consumption intensity mci and investigates the effect of the pure technical and final demand coefficients on the mci of key sectors using a combined input output and sensitivity analysis the results show that the average mci of key industries increased from 7 37 tonnes per ten thousand yuan to 32 13 tonnes per ten thousand yuan during the period from 2002 to 2012 and the manufacturing and processing of the metals sector n14 revealed the greatest mci moreover the elasticity of the mci in terms of the pure technical and final demand coefficients of key sectors also increased rapidly from 2002 to 2012 and the number of corresponding transactions leading to the increase in key sectoral mci significantly increased in terms of the elasticity of the technical coefficients their sensitivity exceeded that of the pure technical coefficients in most cases due to the influence of the demand structure and direct transactions between sectors had important impacts on the mci in most key industries meanwhile almost all the sectors exerted direct or indirect effects on the mci of the mining of metal ores industry n4 in addition the manufacturing of general and special purpose machinery n16 manufacturing of electrical machinery and apparatus n18 and construction n22 exerted influences on most sectors concerning the final demand coefficient elasticity the gross fixed capital formation of most sectors induced the greatest elasticity in the corresponding sectors and the greatest elasticity of all the sectors was related to the gross fixed capital formation of n22

a structural decomposition of global raw material consumption between 1995 and 2008 the global extraction of biomass fossil fuels and minerals grew from 48 to 69 billion metric tons this study investigates how changing consumption and investment patterns a ected the aforementioned increase a series of structural decomposition analyses at a global level as well as for 38 major economies is conducted the analyses disentangle the drivers of raw material consumption which measures the extraction of materials necessary to produce a country s final demand data is taken from the world input output database the results suggest that rising final demand is the predominant driver of growing raw material consumption furthermore final demand shifted into countries that consume material intensive goods this shift was particularly pronounced for construction minerals and investment indicating that infrastructure investment in industrialising nations was a key driver the mix of goods in final demand slightly dematerialised falling material intensities in extractive industries as well as changes in production and trade patterns decelerated the growth of raw material consumption the country level structural decomposition analyses obtained qualitatively similar results

concentration trends in union structure an international comparison the structure of unionism in nine western countries became on the whole more concentrated during the two decades 1957 58 to 1977 78 as indicated by a reduction in the number of national unions affiliated with major federations and an increase in the relative size of the largest unions the reasons for the trend which has implications for the internal life of unions and for collective bargaining are linked to the efforts of unions to adapt their structure to changes in the environments in which they operate often reinforced by pro merger pressures from the central labor federations the trend toward greater concentration may be expected to continue especially in countries in which the major trade union federations are still composed of substantial numbers of affiliated unions

comparison of energy intensities in european union countries results of a structural decomposition analysis abstract this work proposes an input output structural decomposition analysis model to identify the sources of the differences in the energetic intensities of the european union countries given an economic structure a determined composition of the final demand and determined direct energy intensities by countries the work studies to what extent these factors explain the difference in aggregate energy intensities that are observed for different european union countries on the basis of this information indicators are constructed by sectors and countries that allow us to identify the role that each sector or country plays as an energy consumer the results show that the aggregate total energy differences in europe are strongly influenced by the direct energy intensity effect and by the demand effect without the different economic structures of the countries being an important factor in the explanation of these differences the metallurgical and manufacturing products sectors are identified as the most intensive in the aggregate energy intensity

a reconsideration of import substitution this paper studies the origins of an import substitution strategy of development summarizes the consequences of that strategy and reviews the problems that led to its failure the fundamental difficulty was its discouragement of the indigenous social learning necessary for sustained independent development the emergence of an outward oriented minimal government strategy is due to the success of korea and taiwan this strategy fails to recognize that social learning requires a strong role for national agents and that this role can be penalized by undue openness an effective strategy must protect and induce domestic learning without penalizing exporting

material implication of chile s economic growth combining material flow accounting mfa and structural decomposition analysis sda abstract over the last three decades the economic integration of the chilean economy into global markets has been taking place at a rapid pace for example in 1986 exports represented 29 of gdp while in 1996 they had increased to 38 of gdp this period of time was characterized by strong economic growth with an average annual growth rate of about 10 from a physical perspective material requirements more than doubled from 220 to 500 million tons of direct material inputs dmi during the same decade the rate of material growth requirements was around 13 per year the main objective of this study is to explain the changes in dmi by using a structural decomposition analysis sda the changes in material flow accounting mfa were broken down into the effects caused by changes in resource use per unit of output material intensity effect changes between and within sectors structural change effect changes in the composition of final demand mix effect changes due to shifting shares of domestic final demand and export categories category effect and finally changes in the overall level of economic activities level effects the results as a percentage of the total level of dmi used in 1986 indicate that economic growth was the major source of material changes 109 the material intensity and category effects explained 31 and 14 of the increase respectively the increase in the material intensity is mainly due to a declining quality of ores in copper production however these components were partly compensated by the structure 14 and mix 13 effects therefore for a southern american country such as chile the main causes of these changes in material consumption have been a combination of the nature of economic growth along with an increase in export production and material intensity of production

economic growth and atmospheric pollution in spain discussing the environmental kuznets curve hypothesis abstract the environmental kuznets curve ekc hypothesis posits an inverted u relationship between environmental pressure and per capita income recent research has examined this hypothesis for different pollutants in different countries despite certain empirical evidence showing that some specific environmental pressures have diminished in developed countries the hypothesis could not be generalized to the global relationship between economy and environment at all in this article we contribute to this debate analyzing the trends of annual emission flux of six atmospheric pollutants in spain the study presents evidence that there is not any correlation between higher income level and smaller emissions except for so2 whose evolution might be compatible with the ekc hypothesis the authors argue that the relationship between income level and diverse types of emissions depends on many factors thus it cannot be thought that economic growth by itself will solve environmental problems

income growth and atmospheric pollution in spain an input output approach abstract the relationships between economic growth and environmental pressures are complex since the early nineties the debate on these relationships has been strongly influenced by the environmental kuznets curve hypothesis which states that during the first stage of economic development environmental pressures increase as per capita income increases but once a critical turning point has been reached these pressures diminish as income levels continue to increase however to date such a delinking between economic growth and emission levels has not happened for most atmospheric pollutants in spain the aim of this paper is to analyse the relationship between income growth and nine atmospheric pollutants in spain in order to obtain empirical outcomes for this analysis we adopt an input output approach and use namea data for the nine pollutants first we undertake a structural decomposition analysis for the period 1995 2000 to estimate the contribution of various factors to changes in the levels of atmospheric emissions and second we estimate the emissions associated with the consumption patterns of different groups of households classified according to their level of expenditure

colombian international trade from a physical perspective towards an ecological prebisch thesis abstract prebisch s approach to economic development was based on the notion that there is an international historical division of labour peripheral countries are specialised in exporting primary goods while centre countries export industrial goods the terms of trade for peripheral countries tend to deteriorate this approach can be extended to ecological issues the international centre periphery division does not only involve the monetary exchange of goods and capital but also the physical exchange in which southern countries provide materials and energy so that northern countries can develop their socioeconomic metabolism this metabolic process is guaranteed through cheap prices for primary goods this paper aims to apply and extend prebisch s thought on unequal exchange both monetary and ecological in relation to colombian trade in the period 1970 2002 using material flow analysis

trade and the environment from a southern perspective the relationship between free trade and the environment is one of the main issues of contention between environmental and ecological economics environmental economics assumes a positive relationship between free trade economic growth and environmental policies environmental externalities may cause important damage however trade is not to be blamed for this instead the fault lies with policy inadequacies at the national level on the other hand some ecological economists criticise the assumptions of environmental economics especially the immobility of production factors and the positive correlation between income and environmental quality they plead for measures to prevent deterioration of northern environmental standards in a race to the bottom due to ecological dumping from the south in this paper we argue that neither environmental economics nor northern ecological economics take into account the structural conditions determining the international trade system based on some new empirical evidence on material flows we stress the notion of environmental cost shifting if physical and political ecology perspectives are adopted a southern approach to the trade and environment issue may arise 2001 elsevier science b v all rights reserved

towards an ecological theory of unequal exchange articulating world system theory and ecological economics abstract the focus of this paper is on how an ecological perspective might provide us with an analytically more precise way of defining unequal exchange it is only by looking at the ecological conditions of human economies that we can adequately conceptualize the mechanisms which generate inequalities in distribution considerations of market power aside neoclassical economic ideology has dispelled all possible criteria for assessing a market transaction as unequal or unfair one way to assess the occurrence of unequal exchange may be to look at the direction of net flows of energy and materials concrete productive potential but without falling into the trap of equating productive potential with economic value on the contrary it can be analytically demonstrated that unequal exchange emerges from a kind of inverse relationship between productive potential and economic value the notion of a reasonable market price conceals the fact that what is being exchanged are intact resources for products representing resources already spent if we consider longitudinally along the production process any given set of fuels and raw materials destined to be transformed into a given product plus waste its content of available energy will be inversely related to its utility or price in other words the more of its original energy that has been dissipated the higher its price this means that production i e the dissipation of resources will continuously be rewarded with ever more resources to dissipate generating ecological destruction and global core periphery inequalities as two sides of the same coin

accounting for nitrogen in denmark a structural decomposition analysis abstract this paper examines the environmental economic cycle for nitrogen in denmark based on nitrogen input and output from different economic sectors an input output model is employed together with a nitrogen mass balance to apportion total nitrogen loading by final demand and estimate export and import of nitrogen from foreign trade the changes in agricultural and industrial nitrogen loading from the mid 1960s to the late 1980s are broken down into changes related to different technological and economic factors the analysis reveals that technological change intensified agricultural production and economic growth especially rising exports are the key factors structural shifts changes in commodity mix in the household and production sectors generally being of less importance

the material basis of the global economy worldwide patterns of natural resource extraction and their implications for sustainable resource use policies abstract material flow accounting and analysis mfa has been established as an influential framework for quantifying the use of natural resources by modern societies so far however no reference data for overall scale and trends of global extraction of natural resources and their distribution between different world regions has been available this paper presents the first comprehensive quantification of the material basis of the global economy i e used domestic extraction in a time series from 1980 to 2002 we analyse time trends for major material groups fossil fuels metals industrial and construction minerals and biomass disaggregated into seven world regions this allows for a an illustration of the global economy s physical growth driven by worldwide processes of economic integration over the past decades and b an indication of the worldwide distribution of environmental pressures associated with material extraction the results show that annual resource consumption of the world economy increased by about one third between 1980 and 2002 this indicates that scale effects due to economic growth more than compensated for other effects such as the relative increase of the service sectors contribution to gdp structural effect and the use of new production technologies with higher material and energy efficiency technology effect the observed growth of natural resource extraction is unevenly distributed over the main material categories with metals showing the highest growth rate the regional analysis shows the increasing importance of asia and latin america in global resource extraction on the global level material intensity i e resource extraction per unit of gdp decreased by about 25 indicating relative decoupling of resource extraction from economic growth the paper concludes with policy recommendations for a more sustainable use of natural resources

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

bigger cakes with fewer ingredients a comparison of material use of the world economy the amount of materials used worldwide in production and consumption increased by 56 from 1995 to 2008 using an index decomposition analysis based on the logarithmic mean divisia index we investigate the drivers of material use both on a global and a country scale we exploit a panel dataset of 40 countries accounting for 75 of worldwide material extraction and 88 of gdp from 1995 to 2008 the results show that economic growth and structural change towards material intensive countries explain most of the growth in global material use slight gains in material efficiency and falling importance of material intensive sectors have decelerating effects the country level analysis reveals substantial heterogeneity some nations exhibit stable or falling material use while it increases notably in most countries improving material efficiency is able to dampen growth of material use in important industrializing nations like china or india

resource security competition for global resources strategic intent and governments as owners we develop a resource security theory by examining the intent of acquisitions of scarce resources by multinational firms results suggest that owners of firms can shape the intent of resource acquisitions specifically state owned enterprises soes tend to acquire and pay more for resources for exploration rather than exploitation this is because soes owners governments are most concerned with securing their country s future we contribute to the literature by suggesting that ownership influences resource acquisitions that resource security is of importance to multinational enterprises and that soes invest abroad to safeguard both their own and their home countries future

carbon dioxide emissions in the u s economy a structural decomposition analysis this paper provides an empirical analysis of the impact of various influences on carbon dioxide emissions it incorporates methodological refinements of input output structural decomposition analysis which is the examination of economic change by means of a set of comparative static variations in key parameters of i o tables the analysis is performed using a two tiered klem model which allows for estimation of substitution and technological change effects within and between input aggregates the model is used to decompose the sources of change in co2 emissions in the u s over the 1972 82 timeframe using hybrid energy value tables for the initial and terminal years results show the significant effect of substitution within the energy sector and between energy and other inputs as the leading causes of the decline in carbon dioxide emissions

lobbying for minimum wages using a common agency lobbying framework this paper illustrates how the minimum wage set reflects the interaction between economic and political factors and under what circumstances will the policymaker be induced through lobbying to change the minimum wage specifically when the labor demand elasticity is large lobbying is successful in inducing the policymaker to set the minimum wage in accordance with her political ideology however the paper also shows the conditions under which lobbying will reverse the ideological preference and induce a business friendly government to increase the minimum wage empirical analysis on a panel data for ten canadian provinces gives considerable support for theoretical predictions the real minimum wage decreases in skill adjusted union density and political ideology while larger labor demand elasticity reinforces the influence of political ideology in the presence of lobbying jel j38 d72 d78

the rise and fall of unions the public sector and the private as of the late 1980s american unionism as a whole has been in decline for about thirty years this decline has been concentrated in the unions serving workers in the private sector and contrasts sharply with the growth of public sector unions during much of the same period this paper attempts to explain these divergent trends but takes their existence as given by decline or rise of unionism i refer to changes in the percentage relative number of union adherents among a specified group of workers though i believe that movements in the relative number of union adherents have run parallel to broader but more vague movements of union influence the reader must draw such inferences for himself as best he can a union adherent is assumed to be both a dues payer and covered by a collective bargaining contract possible differences between these two concepts of union affiliation are unimportant for this paper individuals are assumed always to act as if they had compared the costs and benefits of union adherence and chosen adherence if the benefits were greater and otherwise if the opposite applied as used here costs and benefits are limited to hourly compensation wages and fringes employment opportunities and working conditions while ideological preferences undoubtedly influence a small minority of workers it is assumed that such individuals are too few to affect the trends analysed 1 the above assumptions obscure important interdependencies among the decisions of individual workers and those of an employee and his employer for example if an 1i do not deny either that changes in attitudes toward the relative desirability of working under union conditions may have occurred from time to time or that such changes might be of interest however i assume that the dominant factors affecting movements in the quantity of union adherents are changes in the benefits and costs of unionization particularly hourly compensation and employment opportunities

imbalance of carbon emissions embodied in the us japan trade temporal change and driving factors abstract in us japan trade japan ran both economic export surplus and export co2 emission surplus with the us positive net monetary exports for japan were actually a kind of economic losses of the us while positive net export co2 emissions or net co2 emissions embodied in us japan trade were regarded as pollution transfer from u s to japan however due to lack of unified measurement units and standards between the two research fields it is difficult to directly assess whether positive effects of u s via carbon transfer outweigh negative effects caused by economic losses the study transforms absolute values of net monetary exports and net export co2 emissions from 2000 to 2011 in us japan trade into two ratios the ratio of net monetary exports to gdp of u s and the ratio of net embodied co2 emissions to total co2 emissions of the us by comparison the result shows that on average net monetary exports between u s and japan accounted for 0 45 of american gdp while ratio of net export emissions to aggregate consumption based co2 emissions of u s kept about 0 20 during the research period concerned which indicated that negative effects of economic losses in u s outweighed positive effects via carbon transfer in us japan trade furthermore a structural analysis of co2 emissions embodied in us japan trade during the 11 years is given the most significant driver was emission coefficients defined as co2 emissions per unit of energy consumption the driving force of emission coefficients led to dramatic reduction in co2 flows from japan to the us and thus caused decrease of net export emissions which also explained the major reason for the low ratio of export emissions to total co2 emissions of the us finally according to sectoral distributions of co2 flows between japan and the us emission sources of two countries presented different characteristics
