relating the environmental impact of consumption to household expenditures an input output analysis in this paper we evaluate the relationships between household expenditures and the environmental impact categories climate change acidification eutrophication and smog formation by combining household expenditures with environmentally extended input output analysis expenditure elasticities are examined with regression analysis and are compared and interpreted on the basis of insight at the product level with data from the netherlands in the year 2000 we find that environmental impact increases with increasing household expenditures although the degree to which the environmental impact increases differs per impact category climate change and eutrophication increase less than proportionally with increasing expenditures acidification increases nearly proportionally with increasing expenditures whereas smog formation increases more than proportionally it appears that the mix of necessities and luxuries to which an environmental impact is related is essential in explaining the relationship

the increase in brazilian household income and its impact on co2 emissions evidence for 2003 and 2009 from input output tables abstract in recent years brazil has experienced economic growth and a recovery of income that has had a positive impact on the consumption of goods in this paper we evaluate the impact of brazilian household consumption on the co2 emissions for 2003 and 2009 using input output tables from the world input output database we used a semi closed model with eight household groups in order to apply the hypothetical extraction method in the consumption structure of each group further we use the result from the hypothetical extraction to evaluate the impacts of the structure consumption of each household group in terms of co2 emissions we find that there is a trade off between the households greater satisfaction from consumption and the increasing setback in emissions from the restructuring and modification of the consumption basket thus this study contributes to the research on emissions by mapping the recent behavior of the brazilian economy in terms of increased income changes in the consumption structure and their impacts on emissions the paper s aggregated results by income and consumption structure based on the intensity of the emissions and their systemic effects add to the discussions on less polluting production processes more conscious consumption of goods and more rational uses of energy and transportation

energy overview for globalized world economy source supply chain and sink abstract energy use of the globalized world economy is comprehensively overviewed by means of a systems input output analysis based on statistics of 2010 emphases are put on the sources of primary energy exploitation inter regional trade imbalance of energy use via global supply chains and sinks of energy use in final demand the largest final user turns out to be the united states compared with china as the leading energy exploiter the global trade volume of energy use is shown in magnitude up to about 90 of the global primary energy exploited the united states is recognized as the world s biggest energy use importer in contrast to russia as the biggest exporter approximately one third of global primary energy exploited is shown to be embodied in inter regional net trade japan and russia are respectively illustrated to be the world s leading net importer and leading net exporter of energy use for china as the leading energy exploiter about 30 of its exploited energy is for foreign regions final use and 70 for its own final use for the european union as the largest sink region nearly 80 of the energy required in its final use is from foreign regions led by russia as reflected in the results the conventional perspective based only on the direct energy consumption by region inevitably leads to inter regional energy grabbing and carbon leakage which raises a serious concern of regional decrease at the expense of global increase in current context of energy shortage and climate change this global energy overview can provide essential strategic implications at the international national and regional scales for sustainable energy policy making

the impact of domestic trade on china s regional energy uses a multi regional input output modeling to systematically reveal how domestic trade impacts on china s regional energy uses an interprovincial input output modeling is carried out to address demand derived energy requirements for the regional economies in 2007 based on the recently available data both the energy uses embodied in final demand and interregional trade are investigated from the regional and sectoral insights significant net transfers of embodied energy flows are identified from the central and western areas to the eastern area via interregional trade shanxi is the largest energy producer and interregional embodied energy deficit receiver in contrast to guangdong as the largest energy user and surplus receiver by considering the impacts of interregional trade the energy uses of most eastern regions increase remarkably for instance shanghai hainan zhejiang beijing jiangsu and guangdong have their embodied energy requirements 87 49 19 97 13 64 12 60 6 46 and 6 38 times of their direct energy inputs respectively in contrast the embodied energy uses of some central and western regions such as inner mongolia shanxi xinjiang shaanxi and guizhou decrease largely the results help understand the hidden network linkages of interregional embodied energy flows and provide critical insight to amend china s current end reduction oriented energy policies by addressing the problem of regional responsibility transfer

energy embodied in the international trade of china an energy input output analysis abstract growing international trade has not only positively affected the people s republic of china s china s economic development but also expanded the exportation of energy embodied in goods during their production this energy flow out will pose risks to china s rational utilization of natural resources as well as environmental protection in this paper we evaluate the energy embodied in goods produced in china during 1992 2005 and use input output structural decomposition analysis to identify five key factors causing the changes of energy embodied in exports direct primary energy efficiency primary energy consumption structure structure of intermediate inputs structure of exports and scale of exports for the three sub periods of 1992 1997 1997 2002 and 2002 2005 results show that china is a net exporter of energy and the energy embodied in exports tends to increase over time the expanding total volume of exports and increasing exports of energy intensive goods tend to enlarge the energy embodied in exports within all three sub periods but these driving forces were offset by a considerable improvement of energy efficiency and changes in primary energy consumption structure from 1992 to 2002 and the effects of structure of intermediate input only in the sub period from 1992 to 1997 from 2002 to 2005 the sharp augmentation of energy embodied in exports was driven by all the five factors our research has practical implications for the chinese economy results of this study suggest that the energy embodied in trade should receive special attentions in energy policies design to limit the energy resource out flow and pollution generation

growth and enduring epidemic diseases abstract this paper analyzes the interplay of human capital formation and economic growth when there is premature adult mortality failing adequate insurance arrangements a long wave of such mortality can so undermine human capital formation as to induce an economic collapse in nuclear family structures random matching of partners is superior to assortative mating only if the shock is not too big and initial levels of human capital are not too low full pooling of mortality risks with equal treatment of all children in extended families may fend off a general collapse depending on the initial conditions and the size and duration of the shock to avoid undesirable effects on expectations awareness campaigns should be complemented by policies that credibly promise to reduce future mortality if mortality depends on the general level of human capital indeterminacy can arise in the form of more than one rational expectations path

evaluation of the environmental impact of weekly food consumption in different socio economic households in australia using environmentally extended input output analysis this paper uses input output analysis to model the environmental impacts of the weekly food consumption of australia s households sorted by income quintile in 2003 we found that weekly food consumption of the relatively better off households caused greater environmental burden than that of the less well off household meat and bakery products flour cereals were the categories that contributed the largest share of environmental impacts in an average household s food consumption footprint 58 water 26 energy 29 co2 and 31 wasted materials per dollar spent fruit and vegetables generated 0 0874 m3 of water 0 0055 gj of energy 0 37 kg of co2 and 0 0114 kg of wasted materials this was lower than the per dollar impacts of bakery products 0 8482 0 0067 0 63 0 0204 meat 0 3471 0 0070 0 65 0 0203 dairy 0 0995 0 0114 0 98 0 0192 and edible fats 0 2373 0 0080 0 70 0 0165 eating out and fast food consumption also had a low per dollar impact 0 1317 0 0046 0 38 0 0141 we surmise that substituting fruit and vegetables at the expense of animal products processed foods and fats would decrease environmental impacts change at low income levels should be focused upon meat bakery and dairy consumption while higher incomes should be focused upon the consequences of eating food outside the home

on the distributional consequences of epidemics we develop a tractable general theory for the study of the economic and demographic impact of epidemics notably its distributional consequences to this end we build up a three period overlapping generations model where altruistic parents choose optimal health expenditures for their children and themselves the survival probability of adults and children depends on such investments agents can be skilled or unskilled in this paper epidemics are modeled as one period exogenous shocks to the adults survival rates we first show that such epidemics have permanent effects on the size of population and on the level of output however the income distribution is shown to be unaltered in the long run second we show that this distribution may be significantly altered in the medium term in particular the proportion of the unskilled will necessarily increase at that term if orphans are too penalized in the access to education c 2009 elsevier b v all rights reserved

a review of residential tiered electricity pricing in china abstract at present the unformed market oriented pricing mechanism has become a great challenge faced by china s electricity pricing and the unreasonable electricity pricing caused by cross subsidization has become increasingly serious with the economic development and energy shortage tiered electricity price tep which was developed and used since 1970s was introduced into china as a new electricity pricing method for residential electricity consumption the tep can also improve the tariffs the behaviors and the efficiency of residential electricity consumption in this study we use the fundamental theory of the electricity economics to analyze the pricing methods and the forms of china s power market with the reform of electric power industry we also point out the characteristics of residential tiered electricity pricing in china which is also compared with other countries such as the united states and japan the main factors influencing the residential tiered electricity pricing design are discussed in this paper from the perspectives of users the electric power enterprise and government regulation then we point out the main problems of china s existing tiered electricity pricing including inadequate level of public awareness and acceptance unreasonable tiered and electricity price standard insufficient reflection in regional differences less combination with other electricity pricing forms and low level of smart meter application

the role of consumption patterns demand and technological factors on the recent evolution of co2 emissions in a group of advanced economies changes in production structures and modifications of patterns of consumption are key factors in the fight against environmental harm initiatives such as agenda 21 promoted by the un highlight the need to evaluate the relationships among factors of production and consumption innovation and demographics and the environment in the attainment of sustainable development in this context our work studies in depth those factors underlying the economic activity of households in a representative group of european union countries and the us within the framework of an input output model a structural decomposition analysis is considered in order to identify the weight that growth in demand changes in patterns of consumption changes in the distribution of income the substitution of inputs and changes in energy intensity have all had on the evolution of co2 emissions the work specifically seeks to identify common patterns and differential behaviors among productive sectors in the european social environment the results show that growth in demand and therefore in production largely absorbs the limited effect of technological and efficiency improvements and the incipient changes observed in consumption patterns

optimal embodied energy abatement strategy for beijing economy based on a three scale input output analysis abstract energy strategies in china s 11th and 12thzfive year plan failed to reduce the total energy consumption and misled the implementation of energy saving measures as they were focused towards the direct energy input as well as formulated based on incomplete energy consumption information therefore an optimal energy abatement strategy built on comprehensive information on overall embodied energy consumption is in urgent need adopting the three scale input output analysis this study uses beijing as a case to depict a specific urban economy s overall energy consumption impacted by local direct energy use domestic and foreign trade the results show that energy embodied in domestic trade dominated beijing s energy consumption while local direct energy is accounting for less than 1 3 of beijing s total embodied energy consumption the quantity of energy embodied in imports far exceeds that embodied in exports making the city a net embodied energy importer and indicating that policies considering direct energy use only will cause energy leakage problem these findings suggest that the current measures such as displacing energy intensive sectors to other regions lead to local reduction but overall rise moreover analysis for five abatement scenarios average intensity share absolute share discriminatory absolute and discriminatory intensity was carried out to figure out the optimal abatement strategy for beijing due to less loss of potential output it is found that intensity share scenario is the optimal one among all the scenarios concerned analysis in this study suggests that each region should break limits of self centered perceptions and multi scale governance for more appropriate responsibility assignment is recommended for overall energy abatement

financing constraints and investment new evidence from hospital industry data this paper tests for evidence of financing constraints in the u s hospital industry the authors hypothesize that small hospitals and free standing hospitals are more likely to face financing constraints than respectively large hospitals and members of hospital chains they estimate the relationship between liquidity and investment within each cohort controlling for a variety of factors that might affect the marginal profitability of hospital investment the results provide strong evidence that small hospitals and free standing hospitals face borrowing constraints due to agency costs this supports earlier work that found evidence of financing constraints in other contexts copyright 1995 by ohio state university press

economic status and health in childhood the origins of the gradient the well known positive association between health and income in adulthood has antecedents in childhood not only is children s health positively related to household income but the relationship between household income and children s health becomes more pronounced as children age part of the relationship can be explained by the arrival and impact of chronic conditions children from lower income households with chronic conditions have worse health than do those from higher income households the adverse health effects of lower income accumulate over children s lives part of the intergenerational transmission of socioeconomic status may work through the impact of parents income on children s health

achieving low carbon urban passenger transport in china insights from the heterogeneous rebound effect abstract the rapid increase in energy consumption and carbon emissions in china s passenger transportation sector threatens both the environment and the nation s energy security energy efficiency improvements leading to lower fuel consumption are therefore of considerable interest to policymakers trying to achieve low carbon travel however it is well established that higher miles per gallon efficiencies can by reducing the costs of travel lead to some level of increased personal travel the so called rebound effect this paper describes an empirical study to measure the size and also the variability in this effect at the provincial level and what this variability implies for a carbon tax policy this rebound effect is quantified using a two stage almost ideal demand system aids model a backfire effect i e the rebound is 100 is observed in urban passenger transport with disparities in the size of the rebound effect ranging from 114 to 153 among china s provinces the differences in economic development as well as related differences in consumers behavior especially in the behavior of marginal consumers have contributed to this heterogeneity with a larger carbon tax more than 110yuan tonne needed in richer provinces such as jiangsu zhejiang guangdong and fujian in order to bring about similar levels of carbon reductions nationwide

the long run economic costs of aids a model with an application to south africa primarily a disease of young adults acquired immuno deficiency syndrome aids imposes economic costs that could be devastatingly high in the long run by undermining the transmission of human capital the main driver of long run economic growth across generations aids makes it harder for victims children to obtain an education and deprives them of the love nurturing and life skills that parents provide these children will in turn find it difficult to educate their children and so on an overlapping generations model is used to show that an otherwise growing economy could decline to a low level subsistence equilibrium if hit with an aids type increase in premature adult mortality calibrating the model for south africa where the hiv prevalence rate is over 20 percent simulations reveal that the economy could shrink to half its current size in about four generations in the absence of intervention programs to combat the disease and to support needy families could avert such a collapse but they imply a fiscal burden of about 4 percent of gross domestic product gdp

optimal tax subsidy combinations for the flu season this paper uses a dynamic susceptible infected recovered sir epidemic model to identify optimal vaccination policy mixes for the flu season it begins with the solution to the relevant optimal control problem and then gives the derivation of a perfect foresight equilibrium outcome for vaccination behavior in an unregulated market both the optimal and market outcomes are characterized by switching curves in s i state space exact expressions for these are derived the final section discusses taxes and subsidies that can be used to attain the optimal outcome

impact of household consumption on co2 emissions danish household consumption increased by 58 over the period 1966 1992 while co2 emissions only increased by 7 using decomposition analysis we investigated the global co2 impact of danish household consumption from 1966 to 1992 our conclusion is that overall growth in private consumption but not changes in the composition of consumption is the key to understanding the increase in co2 emissions however the effect of growth in private consumption has been partly offset by substantial energy conservation in the energy supply and manufacturing sectors

new methodology for the ecological footprint with an application to the new zealand economy abstract sustainable development has become a primary objective for many countries throughout the world since the late 1980s a major difficulty associated with sustainable development objectives however is the absence of reliable indicators to measure progress towards the goal of sustainability the ecological footprint provides an estimate of the land area necessary to sustain current levels of resource consumption for a given population on an aggregate basis the ecological footprint may be compared with the amount of ecologically productive land available to give an indication of whether consumption patterns are likely to be sustainable this paper proposes the use of a modified form of input output analysis to calculate the ecological footprint the input output approach provides a consistent means of calculating an ecological footprint using data collected as part of the system of national accounts in most developed countries in addition it makes explicit the link between the level of economic activity in a country and its corresponding impact on the environment an application of this methodology to new zealand indicates that it takes 3 49 has of ecologically productive land per year to sustain the average new zealander s current level of consumption

the gift of the dying the tragedy of aids and the welfare of future african generations this paper simulates the impact of the aids epidemic on future living standards in south africa i emphasize two competing effects on the one hand the epidemic is likely to have a detrimental impact on the human capital accumulation of orphaned children on the other hand widespread community infection lowers fertility both directly through a reduction in the willingness to engage in unprotected sexual activity and indirectly by increasing the scarcity of labor and the value of a woman s time i find that even with the most pessimistic assumptions concerning reductions in educational attainment the fertility effect dominates the aids epidemic on net enhances the future per capita consumption possibilities of the south african economy

aids crisis and growth abstract we investigate an olg economy where an aids epidemic influences human capital accumulation and growth through the creation of large numbers of orphans we study how intra family allocations regarding school and work time of children are adjusted in the face of aids within a family and how in turn these adjustments influence accumulation of physical and human capital we compute the aggregate effects of an aids epidemic on human and physical capital accumulation and growth we find that growth effects of an aids epidemic are large some policies such as subsidization of aids medication have relatively small effects

energy requirements of sydney households supporting the lifestyles of the populations of modern cities requires vast quantities of natural resources and leads to environmental stresses such as air and water pollution research into the metabolism of cities therefore aims at understanding the physical flows into within and out of cities with a view to reducing the use of resources and the environmental impacts one important physical indicator is energy use most studies on cities only consider direct or end user energy consumption since the function of cities is to serve the lives of their residents indirect energy use in cities or energy embodied in the consumption of goods and services by its residents can be regarded as being as important as direct energy use however physical models of cities are extremely complex and have difficulty in dealing with boundary issues and hence the indirect resource requirements in this paper we use input output analysis and detailed household expenditure data to yield comprehensive energy use breakdowns for the 14 statistical subdivisions of sydney multivariate regression and structural path analysis spa are used to interpret the results clear correlations can be drawn between energy use and income household size age and degree of urbanity the structural path analysis is used to demonstrate how significant differences in lifestyles between inner and outer areas of sydney leads to different energy use characteristics this final consumption based approach to analysing the energy requirements for households has important implications for measures aimed at reducing energy use which tend to only consider direct energy use d 2004 elsevier b v all rights reserved

economic interpretations of intergenerational correlations science itself for example see galton s 1869 study of the eminence of relatives or his 1889 analysis of the heights of parents and children but extensive use of economic theory to interpret these correlations is much more recent using basic economic concepts such as supply demand investment incentives missing markets and so on theorists hope to explain how and why status is correlated across generations economic theory might provide a unified treatment of a variety of socioeconomic indicators such as earnings income occupation or wealth or it might predict how taxes subsidies and economic regulation affect intergenerational mobility and the operation of markets however while the subject matter earnings consumption wealth occupa tion is clearly interesting to economists it could nonetheless be the case that beyond basic questions of measurement economic theory has not improved our understanding of intergenerational mobility goldberger 1989 is quite explicit in this contention by emphasizing the distinction between genes and environment and by using statistical theory as its main analytical tool the paper by samuel bowles and herbert gintis in this issue implicitly concurs with goldberger we take this challenge very seriously what characterizes an economic approach to mobility while biologists and bowles and gintis distinguish endowments and investments by their source genetic versus environmental factors one focus of economic theorists is motiva

debt investment and endowment accumulation the case of not for profit hospitals abstract not for profit hospitals benefit from special tax rules that allow state authorities to issue tax exempt bonds on their behalf which may affect their investment and financing choices hospitals may respond by increasing their investment in physical assets however they may also engage in tax arbitrage by using the tax exempt debt while maintaining endowment assets the paper combines data from tax information returns and the annual survey of hospitals by the american hospital association for 1993 1996 overall the results are consistent with substantial tax planning by not for profit hospitals of the us 55 9 billion in tax exempt liabilities of hospitals in 1996 as much as us 32 6 billion could have been eliminated if hospitals spent their endowments instead of borrowing furthermore controlling for hospital size in terms of revenues and operating assets endowment assets are associated with a higher ratio of tax exempt or total debt to operating assets in contrast endowment assets are not related to taxable debt suggesting that the effects of the endowment on borrowing are motivated by tax incentives investment and endowment accumulation regressions suggest that increases in debt increase both physical investment and endowment accumulation but these effects are concentrated among cash rich hospitals for which the effects on endowment accumulation effects are larger than the effects on physical investment

primary energy and greenhouse gases embodied in australian final consumption an input output analysis input output modeling of primary energy and greenhouse gas embodiments in goods and services is a useful technique for designing greenhouse gas abatement policies the present paper describes direct and indirect primary energy and greenhouse gas requirements for a given set of australian final consumption it considers sectoral disparities in energy prices capital formation and international trade flows and it accounts for embodiments in the gross national expenditure as well as the gross domestic product primary energy and greenhouse gas intensities in terms of mj and kg co2 e are reported as well as national balances of primary energy consumption and greenhouse gas emissions

comparison of household consumption and regional production approaches to assess urban energy use and implications for policy assessment of urban energy use may proceed by a number of methods here we derive an energy account from local statistics and compare them with an input output io analysis as applied to melbourne australia these approaches highlight different aspects of urban energy use and comparable outputs are presented together to assess consistency to identify complementarities and discuss the insight each approach brings to understanding urban energy the io method captures the direct and embodied primary energy requirements of local household expenditure 235 8 gj capita year while the regional assessment more directly accounts for local production activity 258 1 gj capita year the parity of these results is unexpected for a developed city with a strong tertiary sector sectoral detail reveals differences between the primary energy required by melbourne s economic structure and that ultimately required through the full supply chain relating to household expenditure this is accompanied by an io analysis of the geography of melbourne s energy catchment it is suggested that the io consumption and regional production approaches have particular relevance to policies aimed at consumption behaviour and economic re structuring respectively their complementarity further suggests that a combined analysis would be valuable in understanding urban energy futures and economic transitions elsewhere

energy use embodied in china s construction industry a multi regional input output analysis abstract the rapid urbanization process was bound to produce considerable energy demand in china which increased the pressure on sustainable development this study employed a multi regional input output model to investigate energy use embodied in the consumption and interregional trade of china s construction industry results show that as a typical demand driven sector the construction industry consumed 793 74 million tons of coal equivalent in 2007 which is equal to 29 6 of china s total national energy consumption regions have been divided according to different driving forces for energy increment shanxi liaoning heilongjiang henan and sichuan were identified to be driven by their extensive construction activities and inefficient construction process interregional imports of the construction industry represented a resource dependent geographical distribution energy flows are from resource abundant areas in the central part to resource deficient areas in the eastern coast by contrast energy exports represented a regional discrete distribution which mainly transferred energy in the form of labor mobility and service supply this study provided insight into the current energy consumption status of provincial construction industry from both regional and sectoral perspectives which can be a basis for energy policy making and implementation

how does income redistribution affect households material footprint abstract this paper presents a study of the evolution of spanish households material footprint for the period 2006 to 2013 the method proposed combines the multiregional input output model with spanish national data on household consumption according to social group material footprint has been affected by the 2008 economic crisis in relative terms the share of spanish households material footprint with respect to total material footprint decreased drastically from 70 7 in 2006 to 50 8 in 2011 this reduction can be mainly attributed to the construction sector crash 34 4 of the reduction is due to construction materials followed by biomass 29 metals 27 1 and fossil fuels 26 1 by type of household the material footprint exhibits a scale effect while consumption and income levels grow and this is accompanied by a global teleconnection effect which varies from 62 for biomass to 64 for metals to 82 for construction materials to 95 for fossil fuels given the context of increasing income inequality we perform one redistribution simulation from high to middle and low income households finding a material footprint increase in all cases the most materialized consumer basket is that corresponding to households with incomes between 1500 and 1999 euros above that income level the growing weight of expenditures on services reduces the use of materials importantly social income redistribution and environmental material footprint sustainability will become incompatible if responsibility is transferred only to households

carbon dioxide emissions and global gdp abstract a positive relationship between carbon dioxide emissions the most important greenhouse gas ghg implicated in global warming and gdp is shown in this paper examining per capita income and co2 emissions of 137 countries across 21 years it also appears that as per capita incomes accelerate across countries emissions increases for the most part tend to decelerate it could be that higher income levels lead to increased demand for environmental protection only emissions reduction proposals that assure incomes will not be adversely affected particularly those of less developed countries ldcs will have any possibility of successful implementation

energy requirements of household consumption a case study of the netherlands this article describes the results of several research programmes that together aim at the development and application of methodologies that enable the study of long term environmental effects mainly related to the total household energy demand of household consumption in relation to other economic sectors this is usually described as the household metabolism approach in this article we use energy consumption and co2 emissions as proxies for long term impacts on the environment the major long term environmental effects of several hundred dutch household consumption categories have been determined by means of the hybrid energy analysis methodology total energy consumption and related co2 emission data have been calculated as a function of household income and family type past trends have been studied by a time series 1950 1990 analysis technical reduction potentials have been calculated for mid and long term scenarios it is concluded that the set of methodologies described form a useful tool for the analysis of unsustainable trends in household consumption patterns and associated energy requirements in the past and the present the results indicate that present trends lead towards unsustainability however reversal of these trends is feasible if this starts in the immediate future and if it is maintained for decades c 1999 elsevier science b v all rights reserved

the evolution of household induced value chains and their environmental implications abstract the growing fragmentation of production processes and expansion of international trade in the last decades have increased the scope and complexity of value added chains worldwide causing a rearrangement of sectoral linkages intra and inter regionally in terms of economic spillovers this implies that a dollar entering a particular economy nowadays follows a different path than a decade before permeating in longer interregional feedback loops and creating additional multiplier effects outside its region of origin however it also implies that the environmental burden that such this dollar generates has changed in scale and spatial distribution in this paper we explore the evolution of these paths over the period 1997 2008 and highlight the main drivers of observed structural changes that contribute to the surge or decline of the spatial distribution of economic spillovers and greenhouse gases emissions we specifically study the effects of an increase in income in the united states the country with the largest trade volume in the world we introduce an extended version of the temporal leontief inverse tli framework that allows tracing the evolutionary path of the american households multiplier in a quasi dynamic fashion isolating the contribution of expenditure patterns income trade and foreign structural change to the temporal evolution we find similar growing multiplier effects inside and outside the us due to services and manufacturing respectively but a declining local environmental burden due to changes in interindustry relations inside the us with declining manufacturing and a reduced emission intensity we also highlight the fragmentation process with declining foreign intraregional spillovers and increasing trade spillovers

structural path analysis and multiplier decomposition within a social accounting matrix framework the main purpose of this paper is to apply structural path analysis to a social accounting matrix sam framework because the sam is a comprehensive essentially general equilibrium data system the whole network through which influence is transmitted can be identified and specified through structural path analysis the latter provides an alternative and much more detailed way to decompose multipliers as compared with the traditional treatment of stone 1978 and pyatt and round 1979 this paper consists of five sections the first one reviews the sam framework as a basis for multiplier analysis and multiplier decomposition in particular the additive decomposition in terms of transfer open loop and closed loop effects is succinctly presented section ii applies this conventional decomposition to a sam of south korea to illustrate with eleven specific cases the effects of an exogenous injection on the endogenous accounts of the sam i e the incomes of the factors household groups and production activities section iii is devoted to the presentation of the elements of structural analysis and more particularly the transmission of economic influence within a structure finally section iv applies structural path analysis to the south korean sam and compares and contrasts the multiplier decomposition which it yields with the alternative decomposition discussed in section ii the comparison is the more significant in that the two decomposition methods are applied to the same eleven selected cases spanning a variety of sectors i e poles of origin for the injection and sectors poles of destination the empirical analysis in section iv suggests that structural path analysis applied to a sam is a potentially operationally useful technique within which a whole series of policy issues can be addressed the final section is devoted to a brief summary and conclusions

from malthus to modern growth can epidemics explain the three regimes we model demographic and economic long run development in a setting where mortality is endogenous and subject to epidemic shocks the model replicates the full transition from malthusian stagnation to modern growth consistent with the historical facts the economy also passes an intermediate post malthusian phase where growth rates of both population and per capita income increase simultaneously as mortality rates fall and become less volatile the escape from the malthusian trap is the result of a series of mild epidemic shocks making it inevitable at some stage but its timing random calibrations show that it can differ by thousands of generations absent differences in exogenous parameters

energy requirements of households in brazil abstract in this study we determine the total direct plus indirect energy requirements of a given set of brazilian households we use a generalized input output model in order to calculate the energy embodied in goods and services purchased by households of different income level in 11 capital cities of brazil our results show that on average the total energy intensity of household expenditure increases with income level although there is a considerable spread in energy intensities within income classes as well as disparities between regions of the country the total yearly average energy requirement per household in brazil in 1995 96 was 173 6 gj 61 of which was indirect with 32 8 gj for the lower income level 66 of which was indirect and 602 2 gj for the higher income level 62 of which was indirect of this total average energy requirement 76 was required for only three consumption categories utilities 31 mobility 28 and shelter 17 this analysis calls for the attention that has to be given not only to the direct energy consumption as motor fuels and electricity for example but also to the consumption categories that encompass an important part of the indirect energy requirement of households in capital cities in brazil

a carbon footprint proportional to expenditure a case for norway abstract motivated by the importance of consumption as an underlying driver of co 2 emissions we examine the link between consumption and co 2 emissions for norwegian households the main goal is to investigate whether there is a decoupling of consumption expenditures and the environmental impact as we move up the income ladder by combining a 2007 norwegian consumer expenditure survey with emission coefficients from an environmental input output model reflecting emissions embodied in both domestically produced and imported goods and services we calculate the per capita carbon footprint the results from the analysis suggest that the per capita carbon footprint is directly proportional to expenditure with an estimated elasticity close to unity implying no decoupling the finding is partly driven by a near zero emission power sector which leads to comparatively low emissions embodied in domestically produced goods and services

infectious disease and preventive behavior in an overlapping generations model abstract this paper incorporates prevalence of disease and agent s preventive behavior i e health investment into a small open overlapping generations model and investigates the dynamic behaviors of the competitive equilibrium allocation using the model it is shown that agents prevalence elastic behaviors which are supported from empirical studies can be obtained and that such agents behaviors cause the cyclicity of the spread of disease we also show that although the agents preventive behavior in a competitive equilibrium may be insufficient because of the existence of external effects a one shot medical aid from foreign countries does not necessarily improve the agents welfare in the pareto sense

evaluation of the soft measures effects on ambient water quality improvement and household and industry economies abstract various ecological footprint calculators carbon footprint calculators and water footprint calculators have been developed in recent years the basic concepts of ecological behaviour record notebooks and of carbon dioxide emission calculators have been developed since the late 20th century the first carbon dioxide emission calculator was developed in 1991 likewise water pollutant discharge calculators have been developed to estimate the effects of soft measures introduced into households to reduce pollutant discharge since 2004 the soft measures which have been developed in japan may consist of a wider framework household sustainable consumption which has been developed in europe and can be referred to cleaner consumption in this research summarisation of the short history of ecological behaviour record notebooks and ecological footprint calculators in japan since the 1980s was conducted and the soft measures in households to reduce pollutant discharge were evaluated for their effects on ambient water quality improvement as well as household and industry economies effects of the soft measures on related industry economies were investigated using an input output table analysis and the effects of the imported goods were evaluated with an import effect matrix which was developed in this research the effects of the soft measures on household expenditures were estimated to be a decrease by 2 5 or usd 285 person 1 year 1 in 2003 2006 the results show that the soft measures positively affect the chemical fibre industry and significantly affect the detergent industry analysis of the import effect matrix proved that the six industries were tightly related through extensive amounts of imported goods the soft measures in households may lead to household sustainable consumption and thus reduce disadvantageous human impacts on water environments the effects of the measures introduced to improve the environment should be qualitatively and quantitatively evaluated to avoid redundant concerns and discord between the environment and the economy which may be worried when the relationship is not well understood

aids and economic growth a human capital approach abstract using a model that combines growth and health capital equations this study analyses the impact of hiv aids on economic growth the econometric results indicate that the epidemic s effects have been substantial in africa the marginal impact on income per capita of a 1 increase in hiv prevalence rate is minus 0 59 even in countries with lower hiv prevalence rates the marginal impacts are non trivial hence while the human and social costs of the hiv aids epidemic are major causes for concern these results indicate that the macroeconomic affects of the hiv aids epidemic are important

the impact of negative cash flow and influential observations on investment cash flow sensitivity estimates abstract kaplan and zingales quart j econ 112 1997 169 and clearly j finance 54 2 1999 673 diverge from the large literature on investment cash flow sensitivity by showing that investment is most sensitive to cash flow for the least financially constrained firms we examine if this result can be explained by the fact that when firms are in sufficiently bad shape incurring cash losses investment cannot respond to cash flow we find that while cleary s results can be explained by such negative cash flow observations the kaplan zingales results are driven more by a few influential observations in a small sample we also record a decline in investment cash flow sensitivity over the 1977 1996 period particularly for the most constrained firms

domestic ghg emissions and the responsibility of households in spain looking for regional differences abstractthe aim of this article is to analyze the responsibilities of spanish households as final consumers for the generation of domestic greenhouse gases emissions ghg by region of residence distinguishing between nuts 1 and nuts 2 autonomous regions the motivation is the process of convergence experimented by spanish regions based on the strong economic growth experienced by the country until 2008 which could results in different emissions responsibilities because of different lifestyles and production structures we examine in depth the relationships between a representative household in each region and its patterns of consumption although we do find a relationship between per capita income and regional responsibility for pollution generation it is based on a demand scale effect which overlaps the effects of the regional consumption patterns thus in the richest regions madrid northeast east despite their having a less polluting pattern than other regions the level of per capita em

income inequality and carbon dioxide emissions the case of chinese urban households abstract this paper draws on chinese survey data to investigate variations in carbon dioxide emissions across households with different income levels rich households generate more emissions per capita than poor households via both their direct energy consumption and their higher expenditure on goods and services that use energy as an intermediate input an econometric analysis confirms a positive relationship between emissions and income and establishes a slightly increasing marginal propensity to emit mpe over the relevant income range the redistribution of income from rich to poor households is therefore shown to reduce aggregate household emissions suggesting that the twin pursuits of reducing inequality and emissions can be achieved in tandem

the inheritance of inequality how level is the intergenerational playing field what are the causal mechanisms that underlie the intergenerational transmission of economic status are these mechanisms amenable to public policies in a way that would make the attainment of economic success more fair these are the questions we will try to answer

vintage human capital demographic trends and endogenous growth we study how economic growth is affected by demographics in an overlapping generations model with a realistic survival law individuals optimally chose the dates at which they leave school to enter the labor market and at which they retire endogenous growth arises thanks to the accumulation of generation specific human capital favorable shifts in the survival probabilities always induce longer schooling and later retirement but have an ambiguous effect on growth the relationship between the growth of population and per capita growth is hump shaped increases in longevity can be responsible for a switch from a no growth regime to a sustained growth regime and for a positive relationship between fertility and growth to vanish

energy intensity and embodied energy flow in australia an input output analysis abstract decoupling energy use from economic growth is critical for improving energy productivity and mitigating climate change input output databases have been increasingly utilised for consumption based energy accounting and for exploring both the direct and indirect influence of energy use this study performed an environmentally extended input output analysis of energy use in australia from 2006 to 2015 to investigate the total energy intensity of industry sectors and the embodied energy flow from sources of energy use to the final consumption of commodities between 2006 and 2015 the national direct energy intensity reduced by an average of 2 per annum nearly all industry sectoral groups reduced their total energy intensity because of direct energy intensity reduction from other or within industry sectoral groups the difference between the embodied energy use in the import and the export had widened making australia a greater net importer of embodied energy with significant outsourcing of direct energy use and associated greenhouse gas emissions despite a slight reduction in per capita direct household energy use 3 the per capita indirect energy use embodied in household commodity consumption increased by 7 as indirect household energy use is more than three times direct household energy use improving end use energy efficiency should also consider the embodied energy in commodities structural decomposition analysis shows that for the studied period population growth and per capita demand for imported commodities are two major contributors for the increased total embodied energy in australia

the impact of cash flows and firm size on investment the international evidence abstract this paper examines the degree to which cash flow availability influences firm investment in six oecd countries in particular we are interested in the extent to which the reliance on internal funds is affected by firm size since there is general agreement that smaller firms have less access to external capital markets and thus should be more affected by the availability of internal funds earlier work has concluded that the documented positive relationship between cash flow and investment is evidence of the existence of financial constraints we first examine all firms regardless of size in each country and we find that the amount of corporate investment is affected by internal resources in all six countries that is internal financing affects firm investment we then repeat the analysis segmenting the sample using three measures of firm size contrary to our a priori expectations we find that the cash flow investment sensitivity is generally highest in the large firm size group and smallest in the small firm size group we deduce that the explanations for these findings are grounded in managerial agency considerations and in the greater flexibility enjoyed by large firms in timing their investments thus we conclude that the degree of sensitivity of a firm s investments to its cash flows cannot be interpreted as an accurate measure of its access to capital markets as do kaplan s zingales l 1997 the quarterly journal of economics 169 215 since small firms are known to have less access to external markets
