energy saving behavior and marginal abatement cost for household co2 emissions abstract this paper attempts to measure consumers perceived net benefits or net costs of energy saving measures in using energy consuming durable goods using the estimated net costs and the volume of co2 reduced by the measures a marginal abatement cost mac curve for the average household s co2 emissions is produced an analysis using the curve suggests that in order to provide households with an incentive to take actions that can lead to co2 emission reductions in using energy consuming durables a high level of carbon price is needed in addition a regression analysis reveals that the net benefits of the measures are larger for households that put a higher priority on energy saving for those living in detached houses for those with a smaller number of persons living together and for those with less income the result of the analysis using the mac curve may suggest that promoting energy saving behavior will require not only a policy to provide economic incentives but also interventions to influence psychological factors of household behavior

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

assessing the effects of wives earnings on family income inequality we argue that the effect of wives earnings can be assessed meaningfully only by comparing the observed distribution of income with a reference distribution the components of the standard decomposition of the gini coefficient have no implicit reference distribution and therefore should not be interpreted as a measure of the effect of an income source on inequality we suggest several intuitive counterfactual reference distributions and illustrate their use with 1979 and 1989 u s data we conclude that wives earnings reduced inequality in that the income distribution would have been less equal in their absence alternative measures of the impact have mixed results

entrepreneurship and income inequality in southern ethiopia this article uses inequality decomposition techniques in order to analyze the consequences of entrepreneurial activities to household income inequality in southern ethiopia a uniform increase in entrepreneurial income reduces per capita household income inequality this implies that encouraging rural entrepreneurship may be favorable for both income growth and income distribution such policies could be particularly successful if directed at the low income low wealth and relatively uneducated segments of the society

inequality of opportunity in energy consumption in china abstract this paper proposes an empirical implementation of the concept of inequality of opportunity in energy consumption expenditure and applies this to data from chinese general social survey cgss we examine the role played by circumstances beyond the control of individuals for instance gender hukou status family background and region of birth in generating inequality in energy consumption expenditure in china this study shows that the relative share of inequality of opportunity ior in energy consumption expenditure in china is 10 02 for the entire sample ior turns out to be larger for the older cohort peaking at 14 40 for the 1955 64 cohort a shapley value decomposition presents that hukou status and region of birth are the two largest contributors to inequality of opportunity across birth cohorts a heterogeneity analysis further shows that more disadvantaged groups for instance female individuals born in the west of rural china with worse family backgrounds are facing more unequal opportunities in energy consumption in china these results suggest that energy policies focused on zero discrimination in opportunities should be encouraged

a decomposition analysis of the trend in uk income inequality post war britain has experienced a number of dramatic demographic and social changes that have undoubtedly influenced the distribution of income there has been a rise in the number of pensioners whose incomes are relatively low a considerable increase in the number of young and old households living on their own and a remarkable expansion in the proportion of working wives the potential importance of these structural changes suggests that their impact on the income distribution needs to be examined systematically before any attempt can be made to interpret the observed trend in overall income inequality adequately the method usually adopted for this purpose attempts to create a comparable time series of distributions based on the structural characteristics pertaining in one particular year for example if we wished to investigate the effect of shifts in the age structure of the population this approach would disaggregate the distribution in one year tl and estimate what the distribution would have been like if the age structure had been the same as that observed in some other year to on the assumption that other distributional characteristics such as ageincome differentials and inequality within age groups remain invariant to this demographic change the comparison between the actual distribution at t1 and the constructed distribution at t1 with to s age structure is taken to indicate the impact of changes in the age structure over the period concerned this comparison can be presented in terms of quantile shares summary measures of inequality or the entire lorenz curves this approach known as shift share analysis or standardising the inequality series see semple i975 love and wolfson i976 dinwiddy and reed i977 royal commission i977 rowley and henderson i978 macleod and horner i980 is perfectly adequate for simple and straightforward structural changes when several changes are occurring simultaneously however it becomes difficult to identify the contribution of the individual factors and to assess their relative importance to the overall trend in inequality furthermore the combined impact of several structural influences will not in general sum up to the inequality change requiring explanation the purpose of this paper is to propose an alternative method of analysing

interorganizational determinants of promotion client leadership and the attainment of women attorneys explanations of gender inequality typically emphasize individual characteristics the structure of internal labor markets or pressures from the institutional environment extending the structuralist and institutional perspectives this article argues that the demographic composition of an organization s exchange partners can influence the demographic composition of the focal organization when the focal organization is dependent upon its partners specifically law firms with women led corporate clients increase the number of partners who are women attorneys data on elite law firms and their publicly traded clients support a bargaining power hypothesis whereby law firms promote women attorneys when their corporate clients have women in three key leadership positions general legal counsel chief executive officer and board director these effects are stronger when the law firm has few clients reinforcing the hypothesis that interorganizational influence is more vital when a focal organization is depe

global microstructures the virtual societies of financial markets using participant observation data interviews and trading transcripts drawn from interbank currency trading in global investment banks this article examines regular patterns of integration that characterize the global social system embedded in economic transactions to interpret these patterns which are global in scope but microsocial in character this article uses the term global microstructures features of the interaction order loosely defined have become constitutive of and implanted in processes that have global breadth this study draws on schutz in the development of the concept of temporal coordination as the basis for the level of intersubjectivity discerned in global markets this article contributes to economic sociology through the analysis of cambist i e trading markets which are distinguished from producer markets and by positing a form of market coordination that supplements relational or network forms of coordination

imputed income from owner occupied housing and income inequality imputed income from owner occupied housing is generally not included in analyses of the distribution of income yet the value of homeownership is undoubtedly an important element distinguishing the economic status of one family from another in this paper using a new method to decompose income inequality by income source we analyze the impact of potential income derived from the net worth of housing on a representative national sample of us homeowners using 1980 survey of residential finance data we find that housing income adds less to inequality per dollar of income than does income from all other sources

carbon inequality at the sub national scale a case study of provincial level inequality in co2 emissions in china 1997 2007 abstract this study asks whether sub national inequalities in carbon dioxide co2 emissions mirror international patterns in carbon inequality using the case study of china several studies have examined global level carbon inequality however such approaches have not been used on a sub national scale this study examines inter provincial inequality in co2 emissions within china using common measures of inequality coefficient of variation gini index theil index to analyze provincial level data derived from the ipcc reference approach for the years 1997 2007 it decomposes co2 emissions inequality into its inter regional and intra regional components patterns of per capita co2 emissions inequality in china appear superficially similar to though slightly lower than per capita income inequality however decomposing these inequalities reveals different patterns while inter provincial income inequality is highly regional in character inter provincial co2 emissions inequality is primarily intra regional while apparently similar global patterns in co2 emissions are not mirrored at the sub national scale

future inequality in co2 emissions and the impact of abatement proposals this paper analyzes future carbon emissions inequality using a group decomposition of the gini index business as usual projections to the year 2100 for 135 countries show inequality in per capita emissions declines slowly next the impact on emissions levels and inequality of the kyoto protocol and other abatement proposals for annex ii countries in 2010 are measured with a focus on the gap narrowing and reranking effects substantial reranking of per capita emissions between annex ii and non annex ii countries will not occur unless the former reduce their emissions by at least 50 versus 1990 levels and the latter continue growing unabated

international inequalities in per capita co2 emissions a decomposition methodology by kaya factors in this paper we provide a methodology for decomposing international inequalities in per capita co2 emissions into kaya multiplicative factors and two interaction terms we use the theil index of inequality and show that this decomposition methodology can be extended for analyzing between and within group inequality components we can thus analyze the factors behind inequalities in per capita co2 emissions across countries between groups of countries and within groups of countries the empirical illustration for international data suggests some points firstly international inequality in per capita co2 emissions is mainly attributable to inequalities in per capita income levels which helps to explain its recent reduction while differences in carbon intensity of energy and energy intensity have made a less significant contribution this result is strongly influenced by the performance of china and india secondly the between group inequality component which is the biggest component is also largely explained by the income factor thirdly the within group inequality component increased slightly during the period something mainly due to the change in the income factor and the interaction terms in a few regions

rethinking inequality decomposition with evidence from rural china we examine inequality decompositions by income source and describe a general regression based approach for decomposing inequality the approach provides an efficient and flexible way to quantify the roles of variables like education and age in a multivariate context we illustrate the method using survey data from china the empirical results demonstrate how sharply different conclusions can emerge for different decomposition rules we explain how these differences reflect the treatment of equally distributed sources of income and we discuss implications for how results from inequality decomposition are interpreted a renewed interest in economic growth political economy and the distribution of income has again placed the economics of income inequality firmly on the academic research agenda relatively poor performances in latin america have been contrasted with success stories in east asia and recent evidence on the changing income distributions of emerging economic giants like china has

remittances and inequality in this paper the authors propose a framework and develop techniques for analyzing the impact of migrant remittances on the distribution of rural income by size and subsequently its impact on rural welfare household data are used to assign numerical coefficients to the impact of net remittances from both internal and international migrants on income inequality in 2 mexican villages the impact of migrant remittances on the distribution of rural income by size depends critically on the degree to which migration opportunities become diffused through the village population on the returns to human capital embodied in remittances and on the distribution of potentially remittance enhancing skills and education across village households our empirical findings demonstrate that in a village where many households contain internal migrants but few have experience migrating to the u s remittances from mexico to us migrants have an unequalizing impact on village incomes while remittances from internal migrants have a favorable effect on the village income distribution by contrast in a village with a long historyh of sending migrants to the us and hence a more ready access to us labor markets us to mexico remittances have an equalizing impact on incomes remittances from internal migrants in this village however embody a large human capital component and are highly correlated with household income hence internal migrant remittances account for a comparatively large share of inequalities in the 2nd village the overall effect of remittances on income inequality is favorable in both villages migration type migration stage and interaction terms all appear to play a role in this context the effects of small changes in remittances upon income inequality and rural welfare in the 2 villages are explored and some implications for migration and rural development policy are considered authors modified

income inequality and efficiency a decomposition approach and applications to china abstract this paper suggests a new interpretation for a decomposition of the theil inequality index when income can be expressed as multiplicative components applying the method to china we find that the impact of technical inefficiency on inter regional inequality has shown a declining trend

distributional aspects of emissions in climate change integrated assessment models the recent failure of copenhagen negotiations shows that concrete actions are needed to create the conditions for a consensus over global emission reduction policies a wide coalition of countries in international climate change agreements could be facilitated by the perceived fairness of rich and poor countries of the abatement sharing at international level in this paper i use two popular climate change integrated assessment models to investigate the path and decompose components and sources of future inequality in the emissions distribution results prove to be consistent with previous empirical studies and robust to model comparison and show that gaps in gdp across world regions will still play a crucial role in explaining different countries contributions to global warming

hazards of the market the continuity and dissolution of interorganizational market relationships the authors propose a theory of the market as an intertemporal process that integrates multiple theoretical perspectives using event history methods thery analyze the dissolution of interorganizational market ties between advertising agencies and their clients as a function of three forces competition power and institutional forces the informal rules of exchange institutionalized in the emergence phase of the advertising services market include exclusivity sole source and loyalty infrequent switching they find that most exchange relationships between advertising agencies and their clients are indeed exclusive and most last for several years but competition power and institutional forces support or undermine these rules most institutional forces reduce the risk of dissolution of agency client ties powerful advertising agencies mobilize resources to increase tie stability but powerful clients mobilize resources to increase or decrease stability competition is the weakest market force but it has a consistent and substantial effect on tie dissolution competition always increases the risk of dissolution they conclude that the market is institutionalized as imperfectly repeated patterns of exchange because competition and changing norms about the duration of market ties destabilize market relationships

are younger generations higher carbon emitters than their elders inequalities generations and co2 emissions in france and in the usa abstract proper understanding of the determinants of household co2 emissions is essential for a shift to sustainable lifestyles this paper explores the impacts of date of birth and income on household co2 emissions in france and in the usa direct co2 emissions of french and american households are computed from consumer budget surveys over the 1980 2000 time period age period cohort estimators are used to isolate the generational effect on co2 emissions i e the specific effect of date of birth independent of the age the year and other control variables the paper shows that french 1935 55 cohorts have a stronger tendency to emit co2 than their predecessors and followers the generational effect is explained by the fact that over their lifespan french baby boomers are better off than other generations and live in energy and carbon inefficient dwellings in the usa the absence of a generational effect on co2 emissions can be explained by the fact that intergenerational income inequalities are weaker than in france persistence of the generational effect once income and housing type is controlled for in france can be explained by the difficulty for french 1935 55 cohorts to adapt to sober energy consumption patterns

international inequality in energy intensity levels and the role of production composition and energy efficiency an analysis of oecd countries abstract this paper analyses the inequality of energy intensity levels between oecd countries its causes and evolution the paper develops a methodology which allows the inequality in energy consumption per capita to be decomposed into explanatory factors it also analyses the contribution of different groups of countries to this inequality the results show that although differences in affluence are the most significant factor in explaining inequality in energy consumption per capita the inequality in energy intensity levels plays a prominent role in reducing the inequality in energy consumption per capita over the analysed period the paper also develops a methodology which determines the importance of different production structures and energy efficiency of productive sectors in the differences in energy use per unit of gdp between the countries analysed the results show that sector specialisation becomes increasingly important in explaining the inequality of energy intensity while there is a significant trend towards the convergence of energy efficiency between countries sector by sector this trend would explain the decreasing weight of energy intensity as an explanatory factor of the inequalities in energy consumption per capita

applying quantile regression and shapley decomposition to analyzing the determinants of household embedded carbon emissions evidence from urban china abstract as co2 emissions differ in households with different characteristics mitigation policies still address the contributions of these characteristics and their effects on specific households using a representative resident survey in urban china this paper compares how household characteristics differ in their associations with household embedded carbon emissions heces at different levels by quantile regression then this paper analyzes the contributions of these characteristics by shapley decomposition the findings include the following i household income is the most important contributor to the difference of heces and its positive effect increases as heces rise ii the use of wealth has different effects on heces because household housing ownership and deposits contribute little to heces but the positive effects of household car ownership contribute 25 8 iii young people and children will emit more heces than adults the employed emit more than persons who are unemployed or retired iv education increases heces overall but mainly at the low quantiles the negative effect of the marriage increases as heces rise v income car ownership marital status size and constitution of households with high heces should be addressed to reduce the inequality of heces indeed education on the low carbon concept is another way forward

migration remittances and inequality a sensitivity analysis using the extended gini index abstract this paper uses the extended gini inequality index to examine the sensitivity of measurements of impacts of migrant remittances on the distribution of household income by size to different value judgements when measuring inequality the results illustrate the robustness of earlier findings that the impacts of migration on village income distributions differ for different types of migration and for different periods in a village s migration history the magnitude of these impacts however appears to be quite sensitive to the weights attached to incomes at different points in the village income distribution for example in a village with considerable mexico to u s migration experience remittances from mexico to u s migrants have a favorable effect on the village income distribution however the extended gini analysis shows that this favorable impact decreases as more weight is attached to incomes in the poorest households this finding is consistent with the view that barriers to high paying mexico to u s migration work exist for households at the bottom of the village income distribution

young and no money never mind the material impact of social resources on new venture growth although growth is a desirable outcome for new ventures due to the many advantages of large size most new firms fail to grow largely because of their limited resources and adaptability this paper addresses the question of how new ventures grow despite their limited financial resources i explore the effect of two specific nonfinancial social resources legitimacy and status on new venture growth i propose that new firms can acquire legitimacy by mimicking the structures and ceremonial activities of established firms in their industry and can acquire status by affiliating with high status entities using a unique panel data set on a cohort of advertising agencies founded in new york and chicago between 1977 and 1985 i show that legitimacy and status have favorable impacts on new firms growth in revenues and number of employees the paper makes important contributions to social embeddedness and institutional research by examining the strategic implications of firm level social resources and to the literature on entrepreneurship in general and new venture growth in particular

the conditional nature of embeddedness a study of borrowing by large u s firms 1973 1994 economic and organizational sociologists have increasingly demonstrated that the actions of individuals and firms are affected by the social networks within which they are embedded in recent years scholars have begun to recognize that the effects of these social networks may vary across populations or types of relations this article examines the extent to which the effects of interfirm networks on the behavior of firms are historically contingent focusing on the level of debt financing among approximately 140 large u s corporations over a 22 year period the authors show that the extent to which the firms use of debt was influenced by those with which they were tied through director interlocks declined over time the authors argue that this decline in the network effect reflected a shift in the institutional environment within which the firms operated and that it was driven by three processes the professionalization of the finance function within the firm the internalization of financial decision

decomposing inequality in co2 emissions the role of primary energy carriers and economic sectors emission inequality across countries and the contribution of the energy mix and the sectoral composition of a country s energy use are of central importance to the climate debate we analyze the evolution of inequality in global co2 per capita emissions using both historical data on energy related co2 emissions and future emission scenarios generated with the integrated assessment model remind within our sample of 90 countries the results indicate that the gini index declined from about 0 6 in 1971 to slightly above 0 4 in 2008 a decomposition of the gini index of total emissions into primary energy carriers indicates that this reduction is mainly attributed to declining shares of emissions from coal peat and oil in total emissions and decreasing emission inequality within all fossil primary energy sources from the perspective of economic sectors the decline in overall inequality is almost entirely due to a decline of the contribution of emissions from manufacturing construction our analysis also suggests that an equally spread emission reduction from any one source would not have a major impact on overall emission inequality the analysis of future scenario data indicates that climate policy reduces absolute emission inequality while inducing drastic progressive emission reductions in all regions

indirect carbon emissions of urban households in china patterns determinants and inequality abstract the urban household sector is considered to be an essential source of climate change in order to obtain detailed information concerning the description of household consumption activities this paper combined consumer lifestyle approach and input output analysis to estimate indirect carbon emissions of urban household from 2002 to 2012 besides we further analysed the driving forces and inequality of indirect carbon emissions the results showed that the total indirect carbon emissions during the study period increased rapidly rising from 894 08 mtco2 to 1957 03 mtco2 more than 58 of carbon emissions were from 40 of the high income population the highest income group 10 of total urban households deduced 21 of urban indirect carbon emissions the per capita carbon emissions of different households showed a remarkable disparity and the per capita carbon emissions of high income groups decreased from 2011 to 2012 the effective mitigation efforts should focus on reducing carbon intensity and shifting consumption structure for high inequality consumption activities caused by rich households rich urban households should consume less goods and services from this consumption activities for high inequality consumption activities caused by low income households the redistribution of income from rich to poor and low carbon intensity lifestyles may be better options to reduce carbon emissions and inequalities of urban households

transforming rural economies migration income generation and inequality in rural mexico abstract we analyse how migration shapes the distribution and sources of rural income using nationally representative panel data from mexico income source gini decompositions provide some support for the migration diffusion hypothesis nevertheless migration s influence on other income sources and household re ranking substantially alter distributional impacts we find significant impacts of migration on non remittance income as well as changes in the effects of non migration activities on inequality over time we conclude that migration is transforming rural economies in ways that go beyond the scope of most past research on migration and inequality

few opportunities much desperation the dichotomy of non agricultural activities and inequality in western kenya summary using data from western kenya we confirm the existence of a dichotomous non agricultural sector the poverty and inequality implications of the differently motivated diversification strategies only partly correspond to expected patterns while high return activities are indeed confined to richer households low return activities constitute an important income source for households across the entire income distribution finally we examine the wider implications of our findings for rural livelihoods we find that only engagement in high return non agricultural activities is significantly associated with increased agricultural productivity it seems that such high return activities play a key role in triggering cumulative effects of relative livelihood success

the shadow value of migrant remittances income and inequality in a household farm economy this article offers econometric evidence that income remittances sent home by family migrants stimulate household farm incomes indirectly by relieving credit and risk constraints on household farm production a high but unequally distributed shadow value of migrant remittances appears to reinforce an equalising direct effect of remittances on the income distribution across a sample of household farms in rural mexico

geographical spread of global emissions within country inequalities are large and increasing abstract in spite of the extensive literature on greenhouse gas emission inequalities at the world wide level most of the evidence so far has been based on country level data however the within country dimension matters for both the implementation and the policy formation of climate policies as a preliminary step towards a better understanding of within country inequalities this paper measures their extent for the two major greenhouse gases co2 and ch4 over the 1970 2008 period using theil index decompositions we show that within country inequalities account for the bulk of global inequality and tend to increase over the sample period in contrast with diminishing between country inequalities including differences across sectors reveals that between sector inequalities matter more than between country inequalities and between sector inequalities become the dominant source of global inequality at the end of the sample period in the co2 case finally estimated social tensions arising from the disconnection between emissions and future damages turn out to be increasing as soon as within country disparities are taken into account these orders of magnitude should be kept in mind while discussing the efficiency and fairness of alternative paths in combating global warming

distribucion salarial y educacion en lima metropolitana 1970 1984 this paper evaluates tbe effects of educational expansion on the wage distribution in metropolitan lima from 1970 to 19i34 the analysis is based on the dynamic decomposition of the second inequality measured proposed by theil the theil l and makes use of peruvian household surveys the main results suggest that such effects depend on the kind of educational expansion that takes place and that they not necessarily contribute to improve the distribution

inequality of energy intensities across oecd countries a note abstract this paper proposes the use of theil s second measure to analyze international energy intensity differences this index allows differences to be broken down within and between groups of countries in a consistent manner an analysis of oecd countries for the period 1971 1999 shows some basic points first the fall in energy intensities differences is attributable both to within group and between group inequality components second between group inequalities are currently the main contributor to the whole inequality value finally a detailed exploration on within group inequalities reveals the significant explanatory role played by eu countries

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

inequality in co2 emissions across countries and its relationship with income inequality a distributive approach this paper analyses the inequality in co2 emissions across countries and groups of countries and the relationship of this inequality with income inequality across countries for the period 1971 1999 the research employs the tools that are usually applied in income distribution analysis the methodology used here gives qualitative and quantitative information on some of the features of the inequalities across countries that are considered most relevant for the design and discussion of policies aimed at mitigating climate change the paper studies the relationship between co2 emissions and gdp and shows that income inequality across countries has been followed by an important inequality in the distribution of emissions this inequality has diminished mildly although the inequality in emissions across countries ordered in the increasing value of income inequality between rich and poor countries has diminished less than the simple inequality in emissions lastly the paper shows that the inequality in co2 emissions is mostly explained by the inequality between groups with different per capita income level the importance of the inequality within groups of similar per capita income is much lower and has diminished during the period especially in the low middle income group

shocks income and wealth do they affect the extraction of natural resources by rural households summary this paper examines the effects of household and village level characteristics on environmental reliance and participation in resource extraction decisions unlike previous analyses that used case studies or regional samples i use a nationally representative sample of rural households rounds i and ii of the mexico national rural household survey enhrum econometric results show that participation in resource extraction follows an inverted u shaped relationship with income and that environmental reliance decreases with income beyond income results show that relatively wealthy households in rural mexico are less likely to participate in resource extraction and have lower reliance than those with less wealth there is also clear evidence that natural resources provide some sort of insurance for households that are subjected to negative agricultural shocks

a head to head comparison of augmented wealth in germany and the united states we examine the composition of augmented household wealth i e the sum of net worth and pension wealth in the united states and germany pension wealth makes up a considerable portion of household wealth of about 48 percent in the united states and 61 percent in germany when pension wealth is included in household wealth the gini coefficient falls from 0 889 to 0 700 in the united states and from 0 755 to 0 508 in germany if the wealth shares in germany were the same as in the united states this would lead to a 12 6 percent increase in the gini coefficient in the augmented wealth distribution in germany

two decades of the rice economy of thailand 2530 31 2550 51 abstract this paper investigates the transitions in thai rice economy and farm household income structure it also describes the impacts of the changes on income inequalities and poverty indices during 1987 88 and 2007 08 crop years the cost of rice production has continuously increased over time contributing to declining returns despite increasing yields this suggests that the most effective way to raise farmer income is to reduce their production cost without reducing yields practices should be promoted that reduce production costs and maintain yields especially in the use of seed and fertilizer as to household income structure the non agricultural sector contributed a significant and increasing proportion of the farm household s income except in irrigated areas where rice farming still contributes the major part of the total income of households incomeinequality increased over the two decades this inequality occurred in the income from rice farming but other sources of inequality were in the other farm income and agriculture hired labor income despite this growing inequality there was an improvement in poverty situation during the period the incidence of poverty was lower in irrigated development villages than in the other villages keywords rice income distribution poverty reduction

income sources effects on inequality abstract based on certain desirable properties a subset of entropy decomposition rules is proposed to assign inequality contributions to different components of income in addition a method of assessing the impact on inequality of marginal changes in income components originally applied to gini index by lerman and yitzhaki the review of economics and statistics 67 1985 151 is extended to other measures of inequality an empirical exercise based on australian income distribution data illustrates the usefulness of the proposed analytical framework

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

the gini concentration index a review of the inference literature more than a century ago corrado gini proposed his well known concentration index for measuring the degree of inequality in the distribution of income and wealth his index is still extremely relevant and widely used in several fields of research and application in this paper we focus on the inferential properties of the gini index and discuss the main directions of analysis proposed in the literature the aim of the paper is to provide a comprehensive review of the main developments on the inferential aspects of the gini concentration ratio we feel that this work can provide a valuable contribution to those scholars who are approaching the large amount of literature on the inferential properties of the gini index

who emits most associations between socio economic factors and uk households home energy transport indirect and total co2 emissions abstract does the association between household characteristics and household co2 emissions differ for areas such as home energy transport and indirect emissions this question is policy relevant because distributional implications of mitigation policies may vary depending on the area of emissions that is targeted if specific types of households are likely to have higher emissions in some areas than in others so far this issue has not been examined in depth in the literature on household co2 emissions using a representative uk expenditure survey this paper compares how household characteristics like income household size education gender worklessness and rural or urban location differ in their association with all three areas as well as total emissions we find that these associations vary considerably across emission domains in particular whilst all types of emissions rise with income low income workless and elderly households are more likely to have high emissions from home energy than from other domains suggesting that they may be less affected by carbon taxes on transport or total emissions this demonstrates that fairness implications related to mitigation policies need to be examined for separate emission domains

marginal tax rates and income inequality in a life cycle model in this paper we perform computational counterfactual experiments to examine the quantitative impact of marginal tax rates on the distribution of income our methodology builds on previous simulation models developed by auerbach and kotlikoff and fullerton and rogers and uses an algorithm that allows us to examine marginal tax rate structures in their literal form we find that distortions associated with particular marginal tax rate structures have sizable effects on income inequality in a reasonably quantified life cycle setting in our baseline experiments the change in steady state income inequality under 1989 u s income tax rates vis a vis 1984 rates is about half as large as the change actually seen in the data over those two years when measured in terms of a monetary metric derived from gini coefficients

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

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

estimates of trends in global income and resource inequalities it is often argued that the inequality in the world is increasing we study the global income and resource inequality between 1960 and late 1990s income is measured in gdp capita in terms of both current market exchange rate and purchasing power parity ppp consumption of paper energy electricity food animal food as well as emissions of carbon dioxide is also studied changes in the absolute and relative gap between the top and bottom 20 consumers as well as the atkinson measure are used as inequality indicators some remarks are made on how to compare income across countries and how inequality should be measured we find that the inequality in terms of gdp capita measured in ppp terms is rather stable in relative terms but increasing in absolute terms we conclude that inequality as measured by the atkinson index is decreasing for all resources but that the gap in resource consumption in absolute terms is increasing for paper and electricity consumption

poverty and the rural nonfarm economy in oromia ethiopia the rural nonfarm sector has gained increasing importance not only in asia but also in africa it is however widely believed that in most parts of africa the growth of the nonfarm economy has increased inequality and has had a limited effect on the poor who face entry barriers to nonfarm activities the present article analyzes the relation between nonfarm income poverty and inequality in oromia ethiopia we use two complementary methodologies i econometric estimates of household income from the nonfarm sector and ii a gini decomposition of analysis income inequality by source the results consistently indicate that in oromia entry barriers to nonfarm activities is low and the general growth of the sector will benefit the poor

examining the influencing factors of co2 emissions at city level via panel quantile regression evidence from 102 chinese cities ascertaining the influencing factors of carbon dioxide emissions in chinese cities is an important issue for policy makers this paper investigates the effect of several determinants on carbon emis

decomposing inequality in energy related co2 emissions by source and source increment the roles of production and residential consumption abstract using provincial data on energy related co2 emissions in china from 1997 to 2014 and the co2 emission gini coefficient ceg this study evaluates china s spatial inequality in energy related co2 emissions further we decompose this inequality and its variation from the perspectives of production and residential energy consumption using the source decomposition and source increment decomposition methods this paper presents a new ceg source increment decomposition method that can achieve complete decomposition the results reveal a downward trend in china s overall production sector and residential sector co2 emissions inequality although the gini coefficient of co2 emissions from the residential sector is larger than that from the production sector the contribution of the latter to the overall ceg is higher the impacts of the spatial inequality of co2 emissions from china s production and residential sectors depend on the type of energy the concentration effect is the primary factor responsible for inducing changes in china s overall and production sector co2 emissions inequality but it is not the only dominant factor for the residential sector co2 emissions inequality

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

comment on the interpretation and misinterpretation of inequality decompositions by income sources summary this paper discusses interpretations of different inequality decomposition rules when inequality is decomposed by income sources it argues that authors of a recent article based their conclusions on misinterpreted decomposition results it also argues that marginal effects derived as elasticities of inequality with respect to uniform increases in income from each source are easily interpreted and can be compared across different decomposition rules

the seeds of dissolution discrepancy and incoherence in buyer supplier exchange in this research we examine a novel mechanism of interorganizational relationship dissolution incoherence in a partner s behavior we propose that the discrepancy between an exchange partner s opportunistic behavior and the focal firm s expectations may create a state of incoherence and uncertainty and that this effect can be damaging to the exchange even when the partner s behavior is better than expected using nearly 500 longitudinal confidential reports of industrial buyers and sellers we find supportive evidence that 1 the net effect of the discrepancy is initially positive when behavior is better than expected but becomes rapidly negative thereafter and 2 the net effect of the discrepancy is always negative when behavior is worse than expected thus these effects will generally damage the exchange even as the partner tries to improve the relationship this gives insight into why exchange relationships that hit a downward spiral can be difficult if not impossible to salvage we also show that the dysfunctional consequences of discrepancy are mitigated through exchange structures such as the magnitude of dependence on an organizational partner the development phase of the relationship and the presence of bilateral idiosyncratic investments implications for theory and the management of interorganizational relationships are developed

the impact of income inequality on economic residential segregation the case of malmo 1991 2010 as in other western countries in sweden there is a widespread conviction that residential segregation influences the opportunities for residents social mobility and therefore is a cause of income

educational expansion government policy and wage compression abstract the main objective is to measure the elasticity in the response of relative wages by education to relative supplies of educated labour using rigorously comparable urban wage labour market surveys an econometric comparison is made of kenya and tanzania countries which constitute a natural experiment having different secondary education policies but being similar in other relevant respects post primary educational expansion as kenya is an effective means of compressing wages however the tanzanian scarcity premium on post primary education is held down by the alternative means of public sector pay policy the analysis suggests an important role for occupation in the wage adjustment process

embeddedness in the making of financial capital how social relations and networks benefit firms seeking financing i investigate how social embeddedness affects an organization s acquisition and cost of financial capital in middle market banking a lucrative but understudied financial sector using existing theory and original fieldwork i develop a framework to explain how embeddedness can influence which firms get capital and at what cost i then statistically examine my claims using national data on small business lending at the level of dyadic ties i find that firms that embed their commercial transactions with their lender in social attachments receive lower interest rates on loans at the network level firms are more likely to get loans and to receive lower interest rates on loans if their network of bank ties has a mix of embedded ties and arm s length ties these network effects arise because embedded ties motivate network partners to share private resources while arm s length ties facilitate access to public information on market prices and loan opportunities so that the benefits of different types of ties are optimized within one network i conclude with a discussion of how the value produced by a network is at a premium when it creates a bridge that links the public information of markets with the private resources of relationships

inequality and poverty in united states the effects of rising dispersion of men s earnings and changing family behaviour using semiparametric density estimation techniques we analyse the effect of rising dispersion of men s earnings and related changes in family behaviour on increasing inequality in the distribution of family income in the united states for the period 1969 1989 the growing dispersion of men s earnings and changing family structure can account for most of the rise in family income inequality by contrast the increase in labour force participation by women offset this trend inequality grew at a slower rate in the 1990s than in earlier decades largely because of stabilization in the relative earnings of men from low income families

explanatory factors of co2 per capita emission inequality in the european union the design of european mitigation policies requires a detailed examination of the factors explaining the unequal emissions in the different countries this research analyzes the evolution of inequality in co2 emissions per capita in the european union eu 27 in the period 1990 2009 and its explanatory factors for this purpose we decompose the theil index of inequality into the contributions of the different kaya factors the decomposition is also applied to the inequality between and within groups of countries north europe south europe and east europe the analysis shows an important reduction in inequality to a large extent due to the smaller differences between groups and because of the lower contribution of the energy intensity factor the importance of the gdp per capita factor increases and becomes the main explanatory factor however within the different groups of countries the carbonization index appears to be the most relevant factor in explaining inequalities the policy implications of the results are discussed

nonfarm employment and rural welfare evidence from the himalayas the potential importance of nonfarm employment for the welfare of rural households has long been recognized but whether the nonfarm sector offers prospects for improving the welfare of the rural poor remains a contentious issue we examine distributional and well being effects of nonfarm employment of rural households in the himalayas we account for heterogeneity of nonfarm employment and estimate a system of structural equations to better understand the causal linkages between nonfarm employment and household well being the results confirm that disaggregating nonfarm employment activities matters for understanding the relationship between nonfarm employment and rural welfare while low return nonfarm employment is associated with lower income inequality high return nonfarm activities have a disequalizing effect on the distribution of household incomes we also find that the ability to engage in high return nonfarm activities is associated with higher economic well being poor households on the other hand tend to rely on low return activities that do not contribute to improved well being

the distribution of income and wealth of farm operator households because of the relatively low incomes of people associated with farming in the past income maintenance has been a major focus of farm policy the average money income of families earning farm self employment income in 1983 was 93 of the average money income of other u s families usdc however an average income of farm households has lost much of its meaning because it masks a great deal of variation compared to the past farm households represent a heterogenous population presenting a new challenge to policy makers concerned about framing income maintenance policies the current farm bill debate began in 1984 amidst piecemeal information on increased bankruptcies and general financial stress of farms analysis of the financial leverage and cash flow positions of farm businesses has since been forthcoming johnson baum and prescott however information on the financial well being of those households associated with farming has remained limited the purpose of this paper is to describe the financial well being of farm operator households by measuring their size distribution of personal income and farm equity in 1984 the contribution of each source of income to the total inequality of incomes is also analyzed

china s carbon emissions from urban and rural households during 1992 2007 in china rapid economic growth has stimulated fast urban expansion and rural household income and consumption expenditure in current paper an input output method is used to determine the impact of china s increased urban and rural household consumption on carbon emissions the results shows that the direct and indirect co 2 emission from household consumption accounted for more than 40 of total carbon emissions from primary energy utilization in china in 1992 2007 the population increase expansion of urbanization and the increase of household consumption per capita all contribute to an increase of indirect carbon emissions while carbon intensity decline mitigates the growth of carbon emissions therefore at the domestic level household consumption is of great significance for co 2 emission which could be mitigated through changing the composition of goods and services consumed by households and switching to consumption pattern of less carbon intensive products the government must consider the substantial contribution of household consumption to carbon emissions when china is encouraging consumption in order to address the current global financial crisis c 2011 elsevier ltd all rights reserved

wage policies of a russian firm and the financial crisis of 1998 evidence from personnel data 1997 to 2002 the authors use a rich personnel data set from a russian firm for the years 1997 to 2002 to analyze how the firm adjusts wages and employment during this period in which local labor market conditions changed in the aftermath of the financial crisis in 1998 they relate the development of turnover and wages for various employment categories to alternative models of wage and employment determination the authors argue that the firm s behavior is consistent with the predictions of efficiency wage models of the shirking and turnover type

transfer efficiency and distributional impacts of u s farm support evidence from a macro micro simulation the objective of this analysis is to provide insight into the transfer and distributional efficiency of farm support policies a one shot macro micro simulation model weaves together the two prominent threads in the agri cultural decoupling literature that focuses for the first part on economy wide impacts and for the second on the role of cross household het erogeneity experimental shocks to output and land subsidies that generate a 1 increase in net national farm income are compared for the united states with output subsidies shown to have lower transfer efficiency but comparable distributional impact surprisingly a more cou pled approach to policy whereby some agricul tural enterprises are excluded from program participation is found to generate a stronger reduction in inequality this is partially at tributed to the inclusive definition of a farm

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

analysis of the international distribution of per capita co2 emissions using the polarization concept abstract the concept of polarization is linked to the extent that a given distribution leads to the formation of homogeneous groups with opposing interests this concept which is basically different from the traditional one of inequality is related to the level of inherent potential conflict in a distribution the polarization approach has been widely applied in the analysis of income distribution the extension of this approach to the analysis of international distribution of co 2 emissions is quite useful as it gives a potent informative instrument for characterizing the state and evolution of the international distribution of emissions and its possible political consequences in terms of tensions and the probability of achieving agreements in this paper we analyze the international distribution of per capita co 2 emissions between 1971 and 2001 through the adaptation of the polarization concept and measures we find that the most interesting grouped description deriving from the analysis is a two groups one which broadly coincide with annex b and non annex b countries of the kyoto protocol which shows the power of polarization analysis for explaining the generation of groups in the real world the analysis also shows a significant reduction in international polarization in per capita co 2 emissions between 1971 and 1995 but not much change since 1995 which might indicate that polarized distribution of emission is still one of the important factors leading to difficulties in achieving agreements for reducing global emissions

lifetime earnings inequality in germany we employ german social security records to investigate intragenerational lifetime earnings inequality and mobility of yearly earnings for 35 cohorts starting with the birth year 1935 our main result is a striking secular rise of intragenerational inequality in lifetime earnings west german men born in the early 1960s are likely to experience about 85 more lifetime inequality than their fathers in contrast both short term and long term intragenerational mobility are stable longer unemployment spells of workers at the bottom of the distribution of younger cohorts contribute to explaining 20 40 of the overall increase in lifetime earnings inequality

wage inequality and the distribution of education abstract this paper analyzes the relationship between education and wage inequality in metropolitan brazil the study is based on data from ten brazilian annual household surveys pnads which are available for the period 1976 1986 the universe of analysis is limited to occupied prime age males the inequality measure used was theil s second measure which is analytically convenient for a study of the determinants of inequality it is shown that there exist sharp differences in wage inequality across metropolitan areas to identify whether these large regional differences in inequality are directly associated with differences in educational levels or with differences in the steepness of the wage education profiles some simulations are conducted the results indicate that regional differences in the distribution of education are not able to explain much of the regional differences in wage inequality as a matter of fact the differences in wage inequality were shown to be intrinsically associated with differences in the steepness of the wage education profiles

linking yitzhaki s and dagum s gini decompositions in this article we show that the gini coefficient is simultaneously decomposable both by sources of income and by populations of income receivers for nonoverlapping income distributions the so called first best gini multi decomposition we show that this multidimensional decomposition is useful for many reasons i it is related to the degree of inequality aversion of the decision maker ii it is especially well suited to study inequalities between poor and nonpoor people iii it enables one to measure the impact of marginal tax reforms on within and between group inequalities respectively

unemployment shocks and income distribution how did the nordic countries fare during their crises we study the inequality of disposable income in denmark finland norway and sweden during the late 1980s and early 1990s when unemployment rose dramatically in all four countries a standard measure of inequality the gini coefficient was surprisingly stable in all countries during this period by decomposing the gini into income components we test hypotheses about the reasons for this stable income distribution our most straightforward hypothesis that rising unemployment benefits counteracted the impact of more unequally distributed earnings receives only limited support more complex mechanisms seem to have been at work jel classification d30 d31 j60

a matter of relational style loan officer consistency and exchange continuity in microfinance social scientists have long considered what mechanisms underlie repeated exchange three mechanisms have garnered the majority of this attention formal contracts relational contracts and relationally embedded social ties although each mechanism has its virtues all three exhibit a common limitation an inability to fully explain the continuation and stability of intertemporal exchange between individuals and organizations in the face of change drawing on extensive quantitative data on approximately 450 000 microfinance loans made by a microfinance institution in mexico from 2004 to 2008 that include random assignment of loan officers this research proposes the concept of relational styles to help explain how repeated exchange is possible in the face of personnel change we define relational styles as systematically reoccurring patterns of interaction employed by social actors within and across exchange relationships in this paper between microfinance clients and loan officers we show that relati

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

social groups and co2 emissions in spanish households abstract this paper examines the social factors that underlie the composition of final demand and therefore determine the final volume of emissions the study throws light on the relationships between the parameters characterising spanish households income urban rural residence local population density head of household s level of education and social class and their behaviour with regard to consumption and the demand for goods and services on this basis we determine which consumption patterns are best aligned with sustainable growth and development our main conclusion is that the factors analysed determine the volume of emissions for each household in terms of their correlation with income which is the primary determinant of consumption patterns the methodology proposed combines linear sam models and econometric estimation of emissions elasticity with respect to spending

income inequality income composition and macroeconomic trends israel 1979 93 the paper offers several explanations for income inequality trends in israel during 1979 93 two types of analysis are employed decomposition of the gini coefficient by income source and population sub group and time series regression on macroeconomic variables it is found that the slight increase in inequality over the period is a result of opposing forces and that the major difference between the inflation 1979 84 and stabilization 1985 93 periods is in the inequality reducing effect of direct taxes increasing in the first period while declining in the second unemployment had a regressive impact whereas inflation acted as a progressive tax in the first period but not in the second
