household carbon inequality in urban china its sources and determinants designing mitigation policies for households requires knowledge of household carbon distributions this study surveys the household carbon inequality in urban china and analyzes its sources and determinants using weighted household survey data different from existing literatures studying carbon inequality on the international or regional level we focus on the household aspect and first survey its characteristics by some comparisons by ascribing household carbon emissions calculated by the consumer lifestyle approach to several consumption categories with the method of gini coefficient decomposition we find that residential consumption with high carbon intensity is the most important source of household carbon inequality in urban china food consumption and the consumption of educational cultural and recreational services are the next largest sources because of the consumed quantities or carbon intensity the application of shapley decomposition shows the determinants of household carbon inequality in urban china and their contributions which are household demographic characteristics 59 74 household employment and income 24 31 household burdens 8 00 and household assets and financial plans 7 95 the policy implications of these results are also discussed

global water transfers embodied in mainland china s foreign trade production and consumption based perspectives abstract water resources are embodied in global trade although china is the largest water withdrawal economy in the world 50 of its direct water withdrawal is embodied in chinese imports and exports due to an increasing division of activities between different production units economies such as mainland china mainly import intermediate products for further processing and then export final goods to other economies overall mainland china is a net embodied water supplier not only in final consumption based trade relations but also in intermediate production based ones china s total per capita water use is much lower than the global average but yet china exports embodied water through trade activities pakistan myanmar and india are china s largest embodied water suppliers and hong kong the united states and japan are its largest net recipients the main water exporting sectors in mainland china are electrical and machinery sector 9 and textiles and wearing apparel sector 5 respectively and the main importing sector is agriculture sector 1 with imports coming mainly from myanmar pakistan the united states and north korea this analysis of china s global embodied water transfers can inform policies to increase china s water use efficiency and can be generated to build embodied water budgets for a systematic allocation of water resources on the globe especially from the production and consumption based perspectives

analysing pollution by way of vertically integrated coefficients with an application to the water sector in aragon in this paper we adopt pasinetti s approach of vertically integrated sectors in order to disaggregate pollution into its most significant components vertical integration allows us to obtain five components and at least five measurement indices corresponding to each sector and each type of pollution these indices overcome some of the deficiencies of the traditional rasmussen type coefficients the empirical application is carried out by reference to the water sector in aragon a region which lies in north eastern spain for five polluting factors namely water returns biological oxygen demand at five days bod5 suspended solids ss nitrates and phosphates copyright 2003 oxford university press

spatial sustainability trade and indicators an evaluation of the ecological footprint the search for frameworks and indicators of sustainable development has taken a prominent place in this journal however some specific aspects have received little or no attention notably the spatial dimension and the role of international trade in indicator development moreover many sustainable development indicators comprise implicit valuations weighting schemes and policy objectives which are insufficiently recognised as such this contribution tries to highlight these issues by means of a review of a recently proposed indicator for ecological economic analysis namely the ecological footprint that has been developed by wackernagel and rees its concept and calculation procedure are criticised on a number of points and it is concluded that the ecological footprint is not the comprehensive and transparent planning tool as is often assumed in explaining our position we will argue that spatial sustainability and regional sustainable development have not been precisely discussed so far neither in the literature on trade and environment nor in that on sustainable development we will defend the view that trade can contribute positively and negatively to environmental unsustainability consequently indicators and models are needed that allow for analysing interactions and trade offs between such opposite effects 1999 elsevier science b v all rights reserved

macro scale economic influences on tropical forest depletion abstract the paper examines the influence of global and domestic factors on forest depletion in 45 tropical developing countries from 1967 to 1985 it links forest depletion with conditions in the international markets and with domestic macroeconomic and demographic factors calculated elasticities suggest that real exchange rate devaluation debt service food self sufficiency income and export prices of forestry and agricultural output had significant influence on the depletion of tropical forests during the study period

linkages and vertical integration in the chinese economy the original concept of vertical integration can be applied only to the analysis of the relationship between final demand and gross output but is unsuitable for most of supply oriented studies where what matters are the interindustry relations for example vertical integration of an industrial district with the rest of the economy cannot be measured with the traditional technique and should be accounted for by a different measure that considers the direct and indirect demand derived from the whole gross output of the district in such a way it is possible to measure the expansionary potential that any industry has on any other one constructing an index of vertical integration these concepts are then applied to the input output table of a developing country like china and they provide some understanding of the routes development strategies have to follow copyright 1991 by mit press

biophysical assessments in evaluating industrial development an experience from taiwan freshwater aquaculture abstract herman e daly noted in 1992 that maintaining the scale of the physical economy within ecological capacity is vital in pursuing sustainability leading to the use of biophysical assessments as a central concept in sustainability analysis from the perspective of ecological economics accordingly this study provides an empirical support for the key role of biophysical assessments in sustainability analysis by presenting the pictures of taiwan freshwater aquaculture from monetary and biophysical perspectives the analytical results demonstrate that freshwater aquaculture contributes to taiwan s economic prosperity from a monetary perspective but causes land subsidence from the biophysical perspective results of this study also indicate the critical role of spatial dimension in biophysical assessments

scale prices and biophysical assessments abstract in a recent forum on biophysical assessments a number of ecological economists expressed serious reservations about the use of prices to assess the appropriate scale of macroeconomic systems while such reservations are warranted the preference for biophysical assessments over prices indicates that many ecological economists are focussing on one notion of scale and neglecting another altogether there are two notions of scale that are critical to achieving sustainable development sd one is the maximum sustainable macroeconomic scale the other is the optimal macroeconomic scale the maximum sustainable scale is the largest macroeconomic scale that can be sustained by a throughput of matter energy that is within the ecosphere s regenerative and waste assimilative capacities the optimal scale is a preferable macroeconomic scale and is one that is not only sustainable but one that maximises the net benefits of economic activity biophysical assessments are needed to determine the maximum sustainable scale because ecological sustainability is a biophysical problem not an economic problem thus it is through biophysical assessments that the necessary restrictions on the incoming resource flow can be calculated and imposed however since the achievement of an optimal macroeconomic scale is an economic problem albeit a constrained economic problem relative prices are required to efficiently allocate the sustainable resource flow so the macroeconomy can adjust to the optimum failure to recognise the two notions of scale and the most appropriate means of their assessment is likely to thwart rather than advance the movement toward sd

trends in the development of ecological economics from the late 1980s to the early 2000s abstract as the contributions to ecological economics are very diverse recent years have seen some discussion on both how to delimit the field and in which direction it should develop the intention with this paper is to contribute to the discussion by outlining important trends in the development of the field from the late 1980s to the early 2000s the study is inspired by other studies in the sociology and history of science in particular by the theoretical framework regarding scientific fields as reputational organizations which draws attention to both cognitive and social aspects of the formation of a field the basis for the paper is a combination of literature studies interviews with key researchers in the field and participant observations the paper outlines the characteristic cognitive features of ecological economics at the time of the birth of the field it is then described how the development in ecological economics was influenced by broader social factors during the following years and how the field was shaped by the inflow and outflow of different groups of researchers the emergence of different research programmes is outlined as is the organizational development finally the characteristics of ecological economics are summarized and the future prospects are briefly assessed

religion discrimination and trust across three cultures we propose that religion impacts trust and trustworthiness in ways that depend on how individuals are socially identified and connected religiosity and religious affiliation may serve as markers for statistical discrimination further affiliation to the same religion may enhance group identity or affiliation irrespective of creed may lend social identity and in turn induce taste based discrimination religiosity may also relate to general prejudice we test these hypotheses across three culturally diverse countries participants willingness to discriminate beliefs of how trustworthy or trusting others are as well as actual trust and trustworthiness are measured incentive compatibly we find that interpersonal similarity in religiosity and affiliation promote trust through beliefs of reciprocity religious participants also believe that those belonging to some faith are trustworthier but invest more trust only in those of the same religion religiosity amplifies this effect across non religious categories whereas more religious participants are more willing to discriminate less religious participants are as likely to display group biases

reconciling trade and environment towards a comparative advantage for long term policy goals abstract for an economic order to remain within ecological boundaries countries need to respond to ecological feedback effects resulting environmental compliance costs have so far hardly influenced trade flows and firm location decisions future developments of economic integration and the increasing urgency of stricter environmental objectives are shown to change this picture primarily for the case of transnational and global environmental problems countries will need to be relieved from the threat of competitive disadvantage caused by environmental production process regulation that the current international regulatory trade framework implies the first option to do so international harmonization of environmental regulation is connected to a range of shortcomings especially for countries differing in natural endowments and preferences for counterbalancing measures two regulatory frameworks are analyzed based on a a physical inventory system or b a direct environmental compliance cost comparison the adequacy of the physical system is shown to be limited whereas the cost basis option can be applied on a broader range it cannot fully re establish the optimal situation that would be achieved by an often unlikely environmental agreement but would encourage countries to take necessary unilateral environmental action changing current trade regulation in that respect will be crucial to foster sustainable development

tropic trust versus nordic trust experimental evidence from tanzania and sweden undergraduates in tanzania and sweden participated in one trust game one dictator game and answered a standard set of survey questions relating to trust in both countries we detected a strong and significant relation between dictator donations and proportions returned in trust games indicating that unconditional distribution preferences matter in trust game behaviour in sweden incentive compatible evaluations of unrevealed dictator donations significantly predicted the amount sent in trust games the predictive power of survey trust questions differed between countries a plausible relation between survey trust and trust behaviour was found in sweden but not in tanzania

trade environment and development the issues in perspective abstract this special issue on trade and the environment brings together a number of papers that are constructively critical of the conventional economic wisdom on the topic we think that this criticism is warranted because of the decidely uncritical way in which free trade has been advocated in much of the literature and especially in policy the papers analyse the validity of the underlying assumptions on which the conventional wisdom is based and provide suggestions for ways to facilitate trade that is also adequately protective of the environment sustainability and other social values in this introductory piece we discuss trade the environment and sustainability summarizing arguments in the papers included in this issue and adding a few additional points not covered by them

impacts of novel protein foods on sustainable food production and consumption lifestyle change and environmental policy we analyse the impacts of a change in consumers preference for novel protein foods npfs i e a lifestyle change with respect to meat consumption and the impacts of environmental policies e g tradable emission permits for greenhouse gases ghgs or an eu ammonia nh3 emission bound per hectare for our analysis we use a global applied general equilibrium age model that includes consumers lifestyle change different production systems emissions from agricultural sectors and an emission permits system our study leads to the following conclusions firstly more consumption of npfs assists in reducing global agricultural emissions of methane ch4 nitrous oxides n2o and nh3 however because of international trade emission reduction does not necessarily occur in the regions where more npfs are consumed secondly through lifestyle change of the rich the emission reduction is not substantial because more intermediate consumers will increase their meat consumption finally for the same environmental target the production structure changes towards less intensive technologies and more grazing under environmental policy than under lifestyle change

diet shifts towards meat and the effects on cereal us can we feed the animals in 2030 abstract the paper argues that current international projections of meat and feed demand may underestimate future consumption patterns for mainly two reasons demand projections are based on income extrapolation with an assumed demand elasticity and feed requirements per unit of meat are taken to be fixed instead we propose a structural specification that includes a dietary shift towards meat as per capita income increases and we account for a shift from traditional to cereal intensive feeding technologies our finding is that under the commonly assumed growth rates of per capita income world cereal feed demand will be significantly higher in the coming 30 years than is currently projected by international organizations even if we allow for price effects compared to other factors that are generally expected to affect the future world food situation the quantitative impact of the increased cereal feed demand greatly exceeds that of gmos and climate change in the coming three decades

a framework for the practical application of the concepts of critical natural capital and strong sustainability this paper develops a methodology for identifying that natural capital called critical natural capital cnc the maintenance of which is essential for environmental sustainability by consideration of the characteristics of natural capital of the environmental functions that these characteristics enable natural capital to perform and of the importance of these functions to humans and the biosphere it shows how sustainability standards in respect of these environmental functions may be derived the difference between the current situation and these standards is termed the sustainability gap the methodology that emerges from bringing these ideas together into a single analytical framework enables policy makers to identify the extent of current unsustainability the principal causes of it the elements and processes of natural capital the cnc which need to be maintained or restored to close the sustainability gap and the costs of so doing the framework should therefore be of use in identifying priorities and policies for moving towards environmental sustainability

water use in the spanish economy an input output approach against the background of the water limitations that often appear in spain the aim of this paper is to study the behaviour of the productive sectors of the spanish economy as direct and indirect consumers of water to that end we employ input output analysis with the particular methodology being based on the linkages analysis known as the hypothetical extraction method hem we have introduced three modifications to this method first the valuation is made in terms of water consumption secondly we obtain the components of the impacts of each block of activity into which the economy is divided with these components being described as the internal effect mixed linkage net or external backward linkage and net or external forward linkage thirdly this methodology is used to detect key sectors our results confirm the marked importance of the agriculture food and other services blocks as regards the direct and indirect consumption of water in general we also find that other services chemicals metals and electronics and agriculture blocks play an important role in explaining the consumption of drinking water moreover the hem analysis allows us to classify productive sectors according to their forward or backward linkage character in a way that is more precise than that permitted by earlier methods finally this methodology can be extended to other types of environmental pressures 2002 elsevier science b v all rights reserved

integrating sustainable chain management with triple bottom line accounting abstract triple bottom line accounting is widely advanced as a way in which firms can realise broader societal objectives in addition to increasing shareholder value in our analysis of the australian economy we integrate financial input output tables that describe the interdependencies between economic sectors with national social and environmental accounts to construct numerate triple bottom line accounts for 135 discrete sectors the accounts are portrayed against the numeraire of one dollar of gdp thus for a sector of the economy financial aspects of performance can be expressed for example as dollars of export earnings per dollar of gdp social aspects such as employment can be portrayed as minutes of employment generated per dollar greenhouse issues can be portrayed as kilograms of carbon dioxide emitted per dollar since these indicators of triple bottom line performance are referenced against financial units and are consistent with the system of national accounts they can be applied to financial accounts of a firm a service or a product and allow a robust triple bottom line account to be developed across a range of scales the critical advantage of this approach is that it includes both the direct or immediate effects as well as the indirect or diffuse effects associated with a large and distant chain of supply paths the incorporation of most indirect or upstream effects therefore expands the range of issues and effects within the analytical boundary and also includes imports and exports both products and firms can then be assessed properly in sustainable chain management scm terms thus a firm that uses a key intermediate input that requires a large amount of water for example cannot hide the environmental implications since they are revealed in the analysis of the full production chain this revelation can also underpin progress when firms acknowledge both the direct and indirect effects and improve their selection of key inputs on a wider range of criteria rather than on price alone our analysis is well developed at the economic sector level for australia and is also being applied to number of government institutions firms and individual products before the full benefits of numerate triple bottom line accounting can be applied to the equity issues of globalisation trade interdependencies between groups of typical countries will have to be analysed using these whole economy approaches this will allow country specific intensities to be applied to important items in the international production chain

embodied pollution in trade estimating the environmental load displacement of industrialised countries abstract the present paper sets out to aid in the development of environmental load displacement indicators developing the notion of the environmental memory of physical flows we estimated embodied pollution in trade of 18 industrialized countries with a the rest of the world and b developing countries from 1976 to 1994 we found that in the last years of analysis total imports of japan usa and western europe have entailed in general larger air pollutant emissions than local exports the balance of embodied emissions in trade beet seems to follow an inverted u shape across time in japan and western europe and an n shape in the us in the period of analysis japanese and european environmental terms of trade with developing countries improved from the japanese and european point of view whereas american environmental terms of trade with developing countries deteriorated over time although there is no statistical trend between income and embodied emissions in imports in a cross section analysis there does seem to be a positive relationship between both variables at a national level the results suggest that despite many shortcomings this type of assessment may shed useful insights on the international aspects of sustainable development

people s opium religion and economic attitudes since max weber there has been an active debate on the impact of religion on people s economic attitudes much of the existing evidence however is based on cross country studies in which this impact is confounded by differences in other institutional factors we use the worldvalues surveys to id entify the relationship between intensity of religious beliefs and economic attitudes controlling for country fixed effects we study several economic attitudes towardcooperation the government working women legal rules thriftiness andthe market economy we also distinguish across religious denominations differentiating on whether a religion is dominant in a country we find that on average religious beliefs are associated with good economic attitudes where good is defined as conducive to higher per capita income andgrowth yet religious people tendto be more racist andless favorable with respect to working women these effects differ across religious denominations overall we find that christian religions are more positively associatedwith attitudes conducive to economic growth r 2003 elsevier science b v all rights reserved jel classification a1 e0 n4 z1

economic growth and the evolution of water consumption in spain a structural decomposition analysis abstract the aim of this paper is to examine how technology processes of input substitution and changes in final demand all of which underlie economic growth influence water consumption this analysis is undertaken for spain during a significant socio economic period from 1980 the beginning of the democratic era to 2007 the onset of the current economic crisis to this end we construct water consumption series linked to a time series of input output tables generated for the spanish economy and we develop a structural decomposition analysis to study mainly changes in water consumption embodied in final demand we find that the growth in spanish demand all other things being constant would have implied an increase in water consumption almost three times the growth actually observed however this demand effect is largely offset by technology and intensity effects mainly due to changes in agricultural crops given the importance of the demand growth the final demand effect is also analyzed in detail broken down by categories as well as level and composition household demand and the increase of exports appear as key explicative factors

a just and efficient reduction of resource throughput to optimum abstract resource throughput in the economy e g of energy or materials must be progressively reduced by at least one order of magnitude to achieve an optimal level although this would solve the resource distribution conflict between the generations it would also aggravate the resource distribution conflict between persons of the same generation it is shown here that a solution to these two conflicts and efficient resource allocation are only possible if resource certificates are distributed to consumers free of charge and traded between them this paper builds on and integrates ideas developed in h daly s daly h e 1992 allocation distribution and scale towards an economics that is efficient just and sustainable ecological economics 6 185 193 article on allocation distribution and scale adding insights from the ecological footprint concept to propose a mechanism for facilitating intergenerational equity and drastically reducing resource throughput basically the mechanism involves rationing throughput equitably internalizing environmental and social externalities and substituting labour for resource use this can be achieved almost without a drop in prosperity both unemployment and dependence on scarce resources decline

weighting vectors and international inequality changes in environmental indicators an analysis of co2 per capita emissions and kaya factors abstract analyses of international inequality in environmental factors such as the well known co 2 per capita or the kaya factors that is carbon intensity energy intensity and affluence have overlooked the effect that weighting vectors of distance functions and their time variations can have on the evolution of the inequality observed thus for example increases in the relative weight of countries with low emissions tend ceteris paribus to increase the inequality even when the vector of international per capita emissions remains unchanged this effect strictly associated with share variations is assessed in this paper by means of a simple decomposition methodology this methodology allows us to ascertain what part of the time variation of the inequality is attributable to the variations in the shares and or the variations in the environmental variable analysed and in turn suggests extending the analysis to the group components of inequality shorrocks 1980 this proposition is used empirically to assess international inequalities in co 2 per capita and the kaya factors for a variety of sub periods during the 1971 2007 period and for various satisfactory inequality indices

ecologically unsustainable trade abstract international trade although balanced in monetary terms may be unequal in terms of the exchange of biomass and sink capacity it may also be unilaterally or mutually unsustainable if it implies the overuse of the biocapacity in either one or both of the trading partners in this article the ecological footprint concept is used to distinguish different types of ecologically unsustainable trade but the issue of the possible effects of trade on the ecological footprints is also raised we distinguish four such effects an allocative effect an income effect a rich country illusion effect and a terms of trade effect since international trade can be a subtle mechanism by which ecological sustainability is preserved locally by means of importing biomass and sink capacity from other countries it can also blur the view of responsibility for the ecological effects of production and consumption at the end of this article some ethical and political dilemmas related to these issues are raised

plant variety protection in developing countries a report from the field the establishment of intellectual property rights iprs for plant varieties has caused considerable controversy but there is relatively little empirical evidence on performance and options in developing countries this paper summarizes the results of a recent five country study concentrating on the conduct of plant variety protection pvp regimes it examines pvp in the context of other mechanisms that provide incentives for plant breeding it discusses the principal options available to developing countries and examines the ability of pvp to offer protection from competing firms and from on farm seed saving it also looks at the administrative and management requirements of pvp regimes although the paper does not discuss patent protection for biotechnology it examines the ipr requirements for the introduction of transgenic varieties developing countries need to establish an appropriate pvp system but pvp should be seen as part of a broader strategy for seed system development

economic impact of alternative water policy scenarios in the spanish production system an input output analysis abstract this paper analyses the economic impact of alternative water policies implemented on the spanish production system the methodology comprises two versions of the input output price model an average cost formulation and a mark up formulation the input output framework evaluates the impact of the various water policy measures on production prices consumption prices intermediate water use and private real income the results show that a tax on the water used by sectors considerably reduces intermediate water consumption and increases production and consumption prices on the other hand according to jevons paradox improvements in technical efficiency which lead to a reduction in the water requirements of all sectors and an increase in water production raise water consumption the combination of a tax on the water used by sectors and an improvement in the technical efficiency of water in the production sphere takes the pressure off prices and significantly reduces intermediate water consumption

water pollution in the spanish economy analysis of sensitivity to production and environmental constraints abstract in this paper we discuss the relationships between production processes and water pollution based on the recent satellite water accounts swa ine spanish national statistics institute 2002 and the 1997 input output tables for the spanish economy the study focuses on four pollutants biological oxygen demand bod metals nitrogen and phosphorus and seven sector blocks firstly we identify the roles of the various sector blocks as generators and consumers of each type of pollution secondly we examine how pollution responds to changes in unit coefficients of pollution and final demand patterns to obtain the shadow prices for the different pollutants the results obtained provide a sound basis for the design of improvements in environmental policy

allocation distribution and scale towards an economics that is efficient just and sustainable abstract the practical policy of issuing tradeable permits for depletion and pollution requires for its implementation the clear separation of the three basic economic goals of efficient allocation equitable distribution and sustainable scale economic theory needs to catch up with policy in recognizing that scale issues cannot be reduced to either allocation or distribution

econ 101 in need of a sustainability transition abstract ecological economics was one of the first of a number of scientific communities to develop transdisciplinary understandings of the sustainability challenges faced by society as a field with economics in its name ecological economics differs from the other communities and should face the particular task of contributing to the development of a new economics for economics to promote sustainability transitions it is not enough to call for more pluralism a new basic structure of economic knowledge should be developed in order to provide the foundation for a sustainability transition to econ 101 this paper argues that the performativity of economics needs to change and proposes a way of structuring econ 101

integrating sustainability into city level co2 accounting social consumption pattern and income distribution abstract from a sustainability perspective city level co2 emissions require reconsiderations correspondingly the economy environment society nexus should be incorporated into city scale co2 accounting therefore in this study the semi closed io model is integrated with a hem to calculate co2 emissions arising from the social consumption pattern and income distribution and to explore economic drivers behind co2 variations this method is applied to a case study of beijing result demonstrate that beijing in 2012 witnessed something different from that in 2005 1 co2 emissions centred in the internal linkages of a broader class of consumption terms with high economic output mainly driven by interprovincial exports 2 imports increasingly helped decarbonize the mixed net forward and backward co2 linkages of consumption items and 3 income driven co2 emissions excluding demand side parts persisted which were more obvious on the supply side where households have more economy wide effects besides urban households played an essential role in household wide co2 reductions this paper ended with corresponding conclusions policy implications and directions for future work

embodied agricultural water use in china from 1997 to 2010 abstract water is an important element in agricultural production the recent population growth rapid urbanization and fast industrialization present increasing challenges for china s agricultural water use embodied water has been promoted as a substantial indicator for the assessment of water consumption induced by human activities however few studies have investigated the dynamic change in embodied agricultural water use by time series data the findings of such studies may facilitate the development of comprehensive sustainable water usage strategies thus this study quantifies the embodied agricultural water trade as well as production and consumption based agricultural water footprints in china by using an input output model during 1997 2010 according to the results china s average embodied agricultural water intensity shows a declining trend from 43 33 m3 thousand yuan in 1997 to 32 66 m3 thousand yuan in 2010 the average embodied agricultural water intensity of the primary industry is larger than those of the secondary and tertiary industries china has always been a net exporter of agricultural water at the industrial level the primary industry is a net importer because of the increasing food demand in china the secondary industry has consistently been a net exporter and the tertiary industry has maintained a trade balance the production and consumption based embodied agricultural water uses demonstrate similar changing trends both decrease from 1997 to 2007 and then significantly increase in 2010 the embodied agricultural water consumed by the primary industry shows a downward trend whereas those consumed by the secondary and tertiary industries demonstrate an opposite trend therefore in addition to the improvement of agricultural water efficiency adjustments in consumption and trade structure are highly instrumental to the conservation of local agricultural water resources

sharing resources the global distribution of the ecological footprint abstract this paper examines how the human demand on bioproductive lands as measured by the ecological footprint is distributed across the globe using methods commonly used to measure the distribution of income measuring the distribution of natural resource use will be necessary to achieve an economy that is sustainable just and efficient currently different nations place different demands on the environment i e the ecological footprint is not evenly distributed across the globe calculation of the gini coefficient for total ecological footprint and its components explains the sources of inequality in overall resource use calculation of the atkinson index shows how inequality in the ecological footprint is related to the inequality of income and environmental intensity

assessing regional and global water footprints for the uk article i nfo the concept of the water footprint has been recently introduced as an important indicator for human induced water consumption the water footprint is defined as the total volume of water used during production and consumption of goods and services as well as direct water consumption by humans water is not only consumed directly but also indirectly in production processes therefore calculating the water footprint enables us to quantify total water consumed along the whole global supply chain in this paper we develop a regional input output io model extended by water consumption coefficients to quantify the respective domestic water footprint for different consumption categories for the south east and north east of england and the uk i e the water consumed directly and indirectly along the regional supply chain in addition we calculate the total water footprints which include both domestic water consumption and the water required in other countries to produce goods and services imported and consumed in the region under investigation through applying a multi regional input output mrio model both footprints also include households direct consumption of water with regards to the two regions we can observe a very pronounced regional disparity of regional domestic and total water footprints between the relatively water scarce south east and the water rich north east of england we find that the domestic water footprint per capita in the south east is 22 higher than the domestic water footprint per capita in the north east the key water consumers include agriculture food products electricity and gas production and hotel and catering the total water footprints per capita in the south east 1257 m 3 year are more than twice the ones in the north east 597 m 3

political movement and trust formation evidence from the cultural revolution 1966 76 abstract this paper examines the effect of political movement on trust formation in the context of china s cultural revolution 1966 76 an episode that involved conflicts and non cooperative behavior under moral dilemmas combining both county level variation in revolutionary intensity and cohort level variation in trust formation ages we construct individual exposure to the revolution using a difference in differences strategy our findings indicate that individuals in counties with higher revolutionary intensity and of trust formation cohorts report significantly lower levels of trust more than three decades later this effect is more pronounced for those more likely to have been targeted during the revolution as well as those with greater exposure to its early years 1966 71 the results are robust after accounting for the dynamic effects of pre revolution socio economic characteristics an extensive set of region specific cohort trends placebo tests and potential reporting bias

the impact of plant varieties rights on research the case of spain abstract in this paper we study the impact of plant variety rights pvr on the public and private research sectors in spain the objective is to bring to light data bearing on the role of pva in altering research incentives understanding intersectoral differences our results suggest that plant variety rights enactment has had a positive incentive especially for the private sector which increased its market share as a result of higher appropriability conditions the plant breeding sector consists of both international and small domestic firms many foreign breeders focus their research efforts on hybrid varieties which provide natural property rights because of a significance innovative activity of foreign breeders spain has expanded seed imports and reinforced technological dependence

the ecological footprint of poverty alleviation evidence from mexico s oportunidades program abstract we study the consequences of poverty alleviation programs for environmental degradation we exploit the community level eligibility discontinuity for a conditional cash transfer program in mexico to identify the impacts of income increases on deforestation and use the program s initial randomized rollout to explore household responses we find that additional income raises consumption of land intensive goods and increases deforestation the observed production response and deforestation increase are larger in communities with poor road infrastructure this suggests that better access to markets disperses environmental harm and that the full effects of poverty alleviation on the environment can be observed only where poor infrastructure localizes them

national natural capital accounting with the ecological footprint concept abstract there is a growing consensus among natural and social scientists that sustainability depends on maintaining natural capital however progress to put this ecological condition to practice has been slow not least because of the inability of making these objectives measurable therefore to overcome this obstacle assessment frameworks for natural capital are needed this study presents a simple framework for national and global natural capital accounting it demonstrates using the example of italy an accounting framework which tracks national economies energy and resource throughput and translates them into biologically productive areas necessary to produce these flows this calculation has been applied to over 52 countries with this framework based on the ecological footprint concept human consumption can be compared with natural capital production at the global and national level using existing data

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

virtual land use and agricultural trade estimating environmental and socio economic impacts abstract liberalization has caused an increase in the global trade of goods and services in particular the value and physical volume of agricultural goods traded have largely increased as the environmental and social consequences of trade are complex they are rarely included in the national and international agricultural policies one reason is that there is a lack of concepts and methods for assessing the environmental and social impacts of trade policies in this paper we develop a method for quantifying and assessing the land use hidden in the export and import of agricultural goods for the case of switzerland for our analysis we focus on arable crops the first methodological step of our research illustrates the spatial relationship of switzerland with countries all over the world through the import and export of land use for arable crops the second step links this spatial dimension with a qualitative assessment of the environmental and socio economic impacts of agricultural land use we applied the method to the case of wheat cultivation within switzerland and import to switzerland the major problem we were confronted with was the availability of data which had both to be reliable and available for the countries wheat is imported from the results show that the calculation of land use is credible in spite of the problems related with data availability the assessment results for each indicator are in agreement with the current situation in the respective countries in addition the aggregation seems to accurately reflect the countries agricultural polices the developed method is used to estimate the overall environmental and socio economic impacts of an increase in wheat imports to switzerland we argue that this method could be applied for anticipating potential impacts of trade agreements still further research is required for fine tuning of the utility functions including a weighting procedure in the aggregation procedure for practical applications important aspects like water shortage should enlarge our limited set of indicators in addition the average impact on a country level was assessed to refine that different agricultural systems ranging from intensive to extensive to organic should be considered beyond our scope was to analyze impacts due to other life cycle stages than the agricultural production for informed decision however information on the whole life cycle of agricultural products is required

global patterns of materials use a socioeconomic and geophysical analysis abstract human use of materials is a major driver of global environmental change the links between materials use and economic development are central to the challenge of decoupling of materials use and economic growth dematerialization this article presents a new global material flow dataset compiled for the year 2000 covering 175 countries including both extraction and trade flows and comprising four major material categories biomass construction minerals fossil energy carriers and ores industrial minerals first we quantify the variability and distributional inequality gini coefficients in international material consumption we then measure the influence of the drivers population gdp land area and climate this analysis yields international income elasticities of material use finally we examine the coupling between material flows and between income and material productivity measured in economic production per tonne material consumed material productivity is strongly coupled to income and may thus not be suitable as an international indicator of environmental progress a finding which we relate to the economic inelasticity of material consumption the results demonstrate striking differences between the material groups biomass is the most equitably distributed resource economically the most inelastic and is not correlated to any of the mineral materials the three mineral material groups are closely coupled to each other and economic activity indicating that the challenge of dematerializing industrial economies may require fundamental structural transformation our analysis provides a first systematic investigation of international differences in material use and their drivers and thus serves as the basis for more detailed future work

an option perspective on generating and maintaining plant variety rights in china notwithstanding the ambiguous research and productivity promoting effects of plant variety protections pvps even in developed countries many developing countries have adopted pvps in the past few years in part to comply with their trade related aspects of intellectual property rights trips obligations seeking and maintaining pvps reserves options to an expected revenue stream from the future sale of protected varieties the value of which varies for a host of reasons in this article we empirically examine the pattern of pvp applications in china since its pvp laws were first introduced in 1997 we place those pvp rights in the context of china s present and likely future seed markets to identify the economic incentives and institutional influences on decisions to develop and apply for varietal rights

international ecological footprint inequality a methodological review and some results scarcities of environmental services are no longer merely a remote hypothesis consequently analysis of their inequalities between nations becomes of paramount importance for the achievement of sustainability this paper aims on the one hand at revising methodological aspects of the inequality measurement of certain environmental data and on the other at extending the scarce empirical evidence relating to the international distribution of ecological footprint ef most of the techniques currently important in the literature are revised and then tested on ef data with interesting results we consider the underlying properties of different inequality indices those indices which fit best with environmental inequality measurements are cv 2 and ge 2 because of their neutrality property subgroup and source decompositions are also discussed from a methodological perspective empirically this paper contributes to the environmental inequality measurement of ef this inequality has been quite stable subgroup decomposition by using exogenous country groups world bank classification conclude that between group inequality explains almost the totality of international ef inequality source decomposition warns of the dangers of confining co 2 emissions reduction to crop based energies because of the implications for basic needs satisfaction

introduction to the economics of religion after a very long hiatus economists have begun again to study the relationship between economics and religion this article seeks to summarize and evaluate the principal themes and empirical findings that have appeared in some 200 recent papers on the economics of religion although some of the research concerns the economic consequences of religiosity most applies standard economic theory to the study of individual religious activity the characteristics of religious groups and the impact of regulation and competition on religious markets

the multidimensional effects of religion on socioeconomic development a review of the empirical literature religion plays a fundamental role in most people s lives with profound implications for socioeconomic development this survey provides a comprehensive and systematic overview of the causal mechanisms between religion and development discussed and tested in the economics literature and reviews quantitative empirical evidence on the actual effects of religion on economic and social dimensions of development we start by disaggregating the concept of religion into four religious dimensions and propose a framework to conceptualize causal mechanisms numerous mechanisms are possible but only a few uncontested findings exist religion is ambivalent vis a vis development although religious ideas can foster certain forms of human capital acquisition and labor market participation scholars have found a negative relationship between religious dimensions and both income and gender equality as well as innovation activities religious identity is also a source of labor market discrimination and has ambivalent effects on economic growth and social cohesion methodological challenges refer to the availability of fine grained data especially for developing countries the use of concepts and definitions and the lack of causal inference

impact of institutions and public research on private agricultural research abstract the objective of this paper is to present econometric evidence of the effects of economic incentives and institutions on national aggregate private agricultural r d investments an econometric model of national aggregate annual private r d investment is specified and fitted to panel data consisting of seven eu countries austria germany italy the netherlands portugal spain and sweden over 1984 1995 we find strong impacts of both incentives and institutions on private agricultural r d investment including institutional factors strengthens the story and in some cases greatly changes the results

trimming the excess environmental impacts of discretionary food consumption in australia abstract tackling the overconsumption of discretionary foods foods and drinks not necessary to provide the nutrients the body needs is central to aligning human and planetary health whilst the adverse health impacts of discretionary foods are well documented the environmental and broader sustainability impacts of these products deserve more attention especially since their consumption has been increasing in recent decades particularly amongst low income groups this paper presents a quantitative case study analysis of discretionary food consumption and the associated environmental impacts for households from different income groups in australia environmentally extended input output analysis is used to estimate the full life cycle environmental impacts of discretionary food consumption on the basis of household expenditures on average discretionary foods account for a significant 35 39 33 and 35 of the overall diet related life cycle water use energy use carbon dioxide equivalent and land use respectively these significant percentages provide further support for the need to incentivise diets that are both healthier and more sustainable including divestment from discretionary food products the study highlights the challenges ahead including the need for further research on food substitutions to minimise environmental and social impacts whilst maximising nutritional quality especially amongst poorer socioeconomic groups

consumption patterns and their effects on land required for food abstract vast amounts of land are required for the production of food but the area suitable for growing crops is limited in this paper attention is paid to the relationship between food consumption patterns and agricultural land requirements land requirements per food item that were determined in a previous study are combined with data on the per capita food consumption of various food packages varying from subsistence to affluent leading to information on land requirements for food large differences could be shown in per capita food consumption and related land requirements while food consumption expenditure and the physical consumption of specific foods change rapidly over time a difference of a factor of two was found between the requirements for existing european food patterns while the land requirement for a hypothetical diet based on wheat was six times less than that for an existing affluent diet with meat it is argued that in the near future changes in consumption patterns rather than population growth will form the most important variable for total land requirements for food trends towards the consumption of foods associated with affluent lifestyles will bring with them a need for more land lifestyle changes changes in consumer behavior on a household level can be considered as powerful options to reduce the use of natural resources such as agricultural land

environmental sustainability in agriculture diet matters abstract there is no agreement that diet matters for environmental sustainability in the agriculture sector much current agriculture is unsustainable and worsening the environmental impact of agriculture degrades natural capital e g loss of topsoil waste and pollution of water nutrient loss extinction of species cattle raising is one of the most damaging components of agriculture livestock now eat about half of global grain production there is limited scope for improving food supply and what scope there is will further damage the environment all means to improve nutrition especially for the poor will be needed as population increases one such means is to improve diets of the rich by eating lower down the food chain while most people in the world thrive on mainly grain based diets carnivory is high in oecd and is increasing in ldcs in order to reduce food wastage and to improve health and food availability a food conversion efficiency tax is proposed the least efficient converters pork beef would be highly taxed more efficient converters poultry eggs dairy would be moderately taxed most efficient converters ocean fish would be taxed lowest grain for human food would not be taxed while coarse grains might be modestly subsidized non food agriculture also would be taxed highest on tobacco and on starches destined for alcoholic beverages produced from land suitable for food production

water reallocation in the input output model abstract water reallocation between economic agents has been and continues to be the subject of a considerable amount of research this paper proposes a method for evaluating how water is reallocated within the economy in response to changes in final demand and changes in the technical water needs of activities and consumers the empirical application which is for the catalan economy shows important asymmetries in the effects that exogenous inflows and changes in water technical requirements have on water reallocation in the process of water distribution exogenous inflows mostly benefit agriculture and damage private consumers on the other hand increases in technical water requirements have negative effects on agriculture and positive effects on the other production activities and consumers the results of the study suggest that agriculture is an important activity not only in terms of water distribution but also in terms of water reallocation due to changes in final demand and technical water needs

what does it really mean to be a strongly sustainable company a response to nikolaou and tsalis abstract in a recent issue of this journal nikolaou and tsalis 2018 published a paper titled a framework to evaluate eco and social labels for designing a sustainability consumption label to measure strong sustainability impact of firms products in their paper the authors n t develop a method for identifying strongly sustainable companies as a basis for consumer communication n t test their method on a case study of five chemical companies and conclude that two of these are strongly sustainable essentially because they had obtained a higher number of eco labels than the average across the five companies while we agree with n t on the relevance of applying a strong sustainability perspective in the assessment of companies we are afraid that their method can lead to misguided consumer communication at the root of this concern is that n t 1 use a market average as reference to decide whether a company has a strong or weak sustainability performance and 2 use the number of eco labels as an environmental indicator we lay the foundation of this response by briefly accounting for the academic origin of the weak strong sustainability dichotomy we then present our argument against the method presented by n t this is followed by a proposal for how to improve the method finally we discuss state of the art in strong sustainability assessments of companies taking into account other existing methods that draw on the planetary boundaries concept and life cycle assessment

are virtual water flows in spanish grain trade consistent with relative water scarcity abstract virtual water adds a new dimension to international trade and brings along a new perspective about water scarcity and water resource management most virtual water literature has focused on quantifying virtual water flows and on its application to ensure water and food security nevertheless the analysis of the potential gains from international trade at least from a water resources perspective needs to take into account both spatial and temporal variations of blue groundwater and stream flow and green soil moisture water as well as the socioeconomic and policy conditions this paper evaluates whether spanish international trade with grains is consistent with relative water scarcity for this purpose the study estimates the volume and economic value of virtual water flow through international grain trade for the period 1997 2005 which includes 3 years with different rainfall levels the calculations show that spain is a net virtual water importer through international grain trade the volume of net virtual water imports amounts to 3420 4383 and 8415 million m 3 in wet 1997 medium 1999 and dry 2005 years respectively valuing blue water at its shadow price or scarcity value blue water exports oscillate between 0 7 and 34 2 million euros for a wet and dry year respectively overall grain trade is apparently consistent with relative water scarcity as net imports increase in dry years however the evolution of grain exports expressed as a variation in quantity and volume does not match the variations in resource scarcity a disaggregated crop analysis reveals that there are other factors such as quality product specialization or the demand for a standardized product which also influence trade decisions and are not included in the notion of virtual water these facts among others can therefore create potential distortions in the application of virtual water to the analysis of specific trade patterns nevertheless from a water resources perspective virtual water can bring important insights across countries for improving water and land management globally fostering adaptation strategies to climate change and to transboundary resource management

environmental sustainability as the first principle of distributive justice towards an ecological communitarian normative foundation for ecological economics abstract the ecological economic concern with environmental sustainability embodies the normative orientations of the field this concern is foremost a matter of distributive justice the definition of which determines the relevance of the appropriate scale and efficient allocation criteria yet it would appear that the discipline lacks a shared internally consistent set of ethical premises by which this concern might be legitimized various authors have embraced a rawlsian conception of liberal justice as the appropriate banner for ecological economics in place of the consequentialist libertarian foundations of neoclassical economics including environmental economics it is argued here that this is insufficient in so far as it is premised on a vision of a discrete self sufficient economic actor instead it is posited that an ecological economic ethic must proceed from an understanding of the economic actor as community member a recognition implicit in recent ecological economic contributions focused on discourse ethics and deliberative democracy an ecological communitarian conception of distributive justice which views the well being of the individual as inseparable from the integrity of its implicate mutually constituting human and non human natural communities is advanced as the appropriate basis for the ecological economic world view in this light the thermodynamic foundations of ecological economics are seen to provide the necessary departure point for normative decision making oriented towards ensuring sustainability in economic organization

carrying capacity in agriculture global and regional issues abstract much of the debate over world agricultural futures centers on the issue of yield growth optimists in the field base their analyses on a technology and input driven rate of increase in yields which they argue has outpaced population growth and will continue to do so leaving a margin for steady increase in per capita incomes those who are sometimes classified as pessimists we prefer the term ecological realists see practical limits to global and regional carrying capacity in agriculture and maintain that the world is close to or may even have passed these limits projections for world agriculture in the first half of the twenty first century vary widely largely depending on assumptions on yield growth we investigate the pattern of yield growth for major cereal crops and present evidence that the growth pattern is logistic not exponential this pattern is consistent with ecological limits on soil fertility water availability and nutrient uptake projections for supply and demand in the twenty first century based on a logistic rather than an exponential model of yield growth imply that the world is indeed close to carrying capacity in agriculture and that specific resource and ecological constraints are of particular importance at the regional level a supply side strategy of increased production has already led to serious problems of soil degradation and water overdraft as well as other ecosystem stresses this implies that demand side issues of population policy and efficiency in consumption are crucial to the development of a sustainable agricultural system

diet and the distribution of environmental impact abstract this paper examines the relationship between scale and distribution issues it is argued that since achieving a sustainable scale requires economic activity to stay within biophysical limits considerations of equity should not be limited to the distribution of monetary measures such as income but should include the distribution of scarce environmental services as well in order to make this point this paper examines how differences in diet across populations lead to inequality in the distribution of environmental impact first the distribution of food consumption across the world s population is examined using national data next ecological footprints are estimated in order to ascertain how differences in diet affect the distribution of environmental impact the results show that the meat intensive diet enjoyed by many in the industrialized world leads to a greater degree of inequality in the use of environmental services than is apparent from examination of the distribution of food consumption across countries

trade accumulation and uneven development abstract this paper develops a two country model of capital accumulation and growth where the industrial sector exhibits increasing returns to scale it shows that uneven development is a necessary outcome in such a model an initial discrepancy in capital labor ratios between the two countries will cumulate over time leading to the division of the world into a capital rich industrial region and capital poor agricultural region which region takes on which role depends on primative accumulation that is on which region starts with more capital if capital is mobile internationally the model can given rise to a two stage pattern of development a first stage where trade is the engine of growth in the leading country and a second in which foreign investment takes on that role which is reminiscent of the hobson lenin theory of imperialism
