the carbon footprint of uk households 1990 2004 a socio economically disaggregated quasi multi regional input output model this paper presents a socio economically disaggregated framework for attributing co2 emissions to people s high level functional needs based around a quasi multi regional input output qmrio model the study in theory takes into account all co2 emissions that arise from energy used in production of goods and services to satisfy uk household demand whether the emissions occur in the uk or abroad results show that co2 emissions attributable to households were 15 above 1990 levels in 2004 and that although absolute decoupling occurred between household expenditure and co2 during the uk s switch from coal to gas in the early 1990s since then only slight relative decoupling is evident the proportion of co2 that arises outside uk borders in support of uk consumption is rising and reducing these emissions is particularly problematic in a global trading system investigation into the carbon footprint of different segments of the uk population shows wide variation the segment with the highest carbon footprint emits 64 more co2 than the segment with the lowest results show that recreation and leisure are responsible for over one quarter of co2 emissions in a typical uk household in 2004 we conclude that expanding lifestyle aspirations are significant factors in driving household co2 emissions but the study also emphasizes that attention must be paid to the infrastructures and institutions that result in considerable amounts of co2 being locked up in basic household activities through which people meet their everyday needs for subsistence protection and communication with family and friends the findings highlight the sheer scale of the challenge facing uk policy makers and suggest that policies should be targeted towards segments of society responsible for the highest carbon footprints

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

fiscal policy expectation traps and child labor i introduction child labor is widespread in the contemporary world in fact the international labor organization ilo estimates that 246 million of the world s children aged 5 17 or 16 are child laborers most living in developing countries 1 recently there has been renewed interest in this topic among economists which has led to a series of theoretical studies with the aim of better understanding the causes and consequences of child labor in order to help guide appropriate policy responses as in grootaert and kanbur 1995 basu 1999 and basu and tzannatos 2003 for useful literature surveys typically theoretical models designed to address the important policy issues surrounding child labor posit that a family s decision to send a child to the labor market is taken only as a last resort in order to escape the dire consequences of poverty for example basu and van 1998 baland and robinson 2000 show that this response on the part of the family may be stronger in a dynamic setting because contracts between children and adults are not self enforcing and capital markets are incomplete 2 in this case an adult decision maker may not only send their children to work to escape poverty in the present but do so to escape poverty in the future as well this decision will hinder a child s ability to accumulate human capital and can lead to persistent cycles of poverty and child labor across generations 3 we begin by showing that a benevolent government can address the incidence of child labor that results from the non enforceability of intergenerational contracts and incomplete capital markets through the appropriate use of fiscal policy and that this policy is pareto improving it is then shown that if society s confidence in their government is incomplete this lack of confidence can render the same fiscal policy ineffective in other words if households do not believe that the government will follow through on their policy promise then in fact it is quite possible that the government will not be able to follow through on their promise as a result of these beliefs 4 this self reinforcing nature of fiscal policy in the presence of uncertainty can leave a country in an expectations trap with a low level of human capital and child labor 5 to formally demonstrate this fiscal policy expectations trap hypothesis we employ a three period overlapping generations model in which child labor exists 6 this stylized setup will keep the dynamics manageable and allow us to highlight the effects of uncertainty also within this framework we introduce a missing intergenerational contracts market in conjunction with a human capital production function that exhibits a threshold with respect to parental human capital which gives rise to two locally stable steady states there is a good equilibrium where there is a relatively high level of parental human capital which results in a high level of income and no child labor and there is a bad equilibrium where there is a relatively low level of parental human capital which results in a low level of income and positive child labor this low income child labor equilibrium is the standard poverty trap scenario that typically exists in a deterministic economy with multiple equilibria it is then shown that a benevolent government can replicate the missing intergenerational contracts market with a pay as you go social security program thereby eliminating this component of child labor in an economy with perfect foresight in addition it is also shown that this policy is pareto improving in the sense that all generations are strictly better off under this policy except the initial old who are no worse off the dynamics of this social security program are intuitive if child labor is one possible mechanism adults can use to redistribute resources from their children then the government can reduce this incentive by announcing a social security program that will begin during the current adults old age an institutional intergenerational contract

personal carbon allowances a revised model to alleviate distributional issues abstract personal carbon allowances pcas are a policy proposal designed to facilitate carbon emissions reduction and engender carbon consciousness they were investigated by the uk government in 2006 2008 but subsequently shelved with continuing growth of atmospheric co2 concentrations and increasing interest in behaviour change agendas pcas are worthy of fresh development wide variation in energy usage between households of similar incomes implies that under the standard model of pcas significant numbers of low income high emitters would have to purchase top up allowances if pcas penalise some of the worst off in society it creates a major political obstacle to their introduction solving this distributional problem by allocating additional allowances to certain groups or offering compensatory state benefits has been investigated and appears costly and only partially effective this paper proposes a new mean max pca model whereby higher usage is necessary before purchase of top up allowances is required potentially highly effective but consequently the volumes and values of surplus and top up allowances become significantly different this difference renders free market carbon allowance trading unworkable potentially eliminating a hallmark but publicly unpopular pca feature the new model potentially offers the first solution to the distributional problem since it was highlighted in 2008

intertemporal lifestyle changes and carbon emissions evidence from a china household survey abstract this paper examines the endogenous evolution of household consumption patterns and household carbon emissions hces by integrating the analysis methods of income distribution with climate change based on a large scale household survey spanning from 2012 to 2016 in china we estimated the direct and indirect hces observed inverse u shaped carbon kuznets curves ckc and significant changes in hces over the period at the household level applying the oaxaca blinder method we decomposed factors causing the changes in hces and found that income and demographic effects contribute only 25 1 to the total increase of hces the other 74 9 remain unexplained and we define them as the effect of intertemporal lifestyle changes further analysis from multiple perspectives illustrates that the lifestyles of households across various social strata are becoming increasingly higher carbon intensive over time even though the income remains unchanged the findings indicate that existing modeling and projections of carbon emissions based on income and household characteristics may underestimate the future emissions pressure from the household sector hence we conclude that in order to reach more meaningful results the increasing effect of lifestyles should be taken into account when conducting climate change studies and formulating climate policies

optimal reserves in financially closed economies abstract financially closed economies insure themselves against current account shocks using international reserves we characterize the optimal management of reserves using an open economy model of precautionary savings and emphasize several results first the welfare based opportunity cost of reserves differs from the measures often used in the literature second under plausible calibrations the model is consistent with the rule of thumb that reserves should be close to three months of imports third optimal linear rules can capture most of the welfare gains from optimal reserve management but significantly differ from certainty equivalence fourth policymakers should place more emphasis on how to use reserves in response to shocks than on the reserve target itself

modelling household energy expenditures using micro data this paper is concerned with the empirical modeling of domestic demand for energy in the united kingdom at the level of the individual household a two stage budgeting model of household demand for energy conditional on durable ownership is developed at the first stage income is allocated between energy and nonenergy consumption while at the second stage energy expenditure is disaggregated the second stage allocation is assumed to be between gas electricity and a composite good other fuels estimation takes place using a sample of some 50 000 households drawn from the annual u k family expenditure survey for the years 1972 83 a source that has not been fully exploited in the analysis of energy demand to date copyright 1989 by royal economic society

energy burden alleviation and greenhouse gas emissions reduction can we reach two objectives with one policy in this article we assess french current public policies designed to reduce greenhouse gas ghg emissions and abate household energy burden through a simulation of changes in residential sector characteristics over the long run we build on an existing partial equilibrium model to take into consideration key determinants of excessive energy burden among vulnerable households this analysis reveals that current public policies are not sufficient to reach the ambitious objectives for reducing energy consumption and ghg emissions in france moreover the decreases that might occur mask significant social disparities across households the joint implementation of multiple instruments leads to interactions that diminish overall policy outcomes overall current public policies produce estimated free riding rates of 75 energy efficiency measures are thus insufficient in themselves the government should focus more on monetary poverty as a cause of low home improvement rates and consider subsidizing renovation costs as a potential solution

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

the economics of child labor if child labor as a mass phenomenon occurs not because of parental selfishness but because of the parents concern for the household s survival the popular argument for banning child labor loses much of its force however this assumption about parental decision making coupled with the assumption of substitutability in production between child and adult labor could result in multiple equilibria in the labor market with one equilibrium where children work and another where adult wage is high and children do not work the paper establishes this result and discusses its policy implications copyright 1998 by american economic association

residential energy expenditures and the relevance of changes in household circumstances this paper analyses the impact that dwelling characteristics and characteristics and behaviours of household members have on per capita energy expenditures it also analyses whether changes in household socio economic circumstances translate in changes in energy expenditures socio economic characteristics have a moderate impact while dwelling characteristics and especially household size have much larger impacts the largest changes in energy expenditures are due to changes in household size the recent socio demographic trends will make it harder to design policies to effectively reduce the carbon footprint of a country while policies influencing cohabitation and family size may have positive indirect effects

child labor school attendance and intrahousehold gender bias in brazil an extensive survey data set of brazilian households is used to test whether intrahousehold gender bias affects the decisions of mothers and fathers to send their sons and daughters to work and to school an intrahousehold allocation model is examined in which fathers and mothers may affect the education investment and the child labor participation of their sons and daughters differently because of differences in parental preferences or differences in how additional schooling affects son s and daughter s acquisition of human capital brazilian household survey data for 1998 are used to estimate the impact of each parent s education on the labor market participation and school attendance of their sons and daughters for labor market participation the father s education has a greater negative impact than the mother s education on the labor status of sons the father s education also has a greater impact on son s labor status than on daughter s for schooling decisions the mother s education has a greater positive impact than the father s education on daughter s school attendance but fathers have a greater positive impact on sons school attendance than on daughter s

child labour a review of recent theory and evidence with policy implications in recent years a growing number of authors have turned their attention to the question of why children work the purpose of this paper is to review some of the more recent theoretical and empirical research into the topic of child labour and to illustrate the fact that no one factor on its own can account for the phenomenon of child labour therefore policies aimed at eradicating child labour will need to address the broad range of underlying factors that contribute to the incidence of child labour such as poverty market imperfections and access to education

income inequality and carbon consumption evidence from environmental engel curves abstract i investigate the relationship between income inequality and the carbon dioxide co2 content of consumption i quantify the co2 content of household expenditure using input output analysis and estimate environmental engel curves eecs which describe the income emissions relationship using eecs for the united states between 1996 and 2009 i decompose the change in co2 over time and the distribution of emissions across households in both cases income is an important driver of household carbon finally i describe a potential equity pollution dilemma progressive income redistribution may raise the demand for aggregate greenhouse gas emissions i estimate that transfers raise emissions by 5 1 at the margin and by 2 3 under complete redistribution

the poor stay poor household asset poverty traps in rural semi arid india summary although identifying household level poverty dynamics would have important implications for poverty reduction policies empirical evidence is still scant this paper employs a novel semiparametric panel data estimator that combines the advantages of estimation methods in the existing literature and applies it to a uniquely long panel data set to examine poverty dynamics in three villages in rural semi arid india structural immobility is pervasive the currently poor are likely to remain poor suggesting a structural poverty trap while all households face static asset holdings higher castes larger landholders and more educated households are significantly less likely to be poor

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

why children work attend school or stay idle the roles of ability and household wealth abstract this paper offers a theoretical and empirical analysis of child labor schooling and idleness neither work nor school with particular emphasis on the roles of child ability and household wealth in determining these decisions we show theoretically that idleness may be chosen optimally by low income households whose child is of low ability using a rich data set from the philippines we find that while other factors including mother s labor supply the presence of a family business and access to good school quality contribute to these decisions child ability and household wealth are the most important determinants of child idleness and the use of child labor an implication of our findings is that any policy aiming to reduce child labor and increase child schooling should also target improvements in child ability and cognitive development through investments in the nutrition and health of poor children

bounded rationality expectations and child labour this paper develops a model with overlapping generations where the household s optimal fertility child labour and education decisions depend on the parents expectations or beliefs about the return to education it is shown that there exists a range of parental income where the fertility rate is high and children participate in the labour market and receive an incomplete education if a parent believes the return to education is low the act of participating in the labour market reduces the child s ability to accumulate human capital thus the action of sending a child into the labour market is sufficient to ensure that the parents initially pessimistic expectations are fulfilled it is then shown that a one time policy intervention such as banning child labour and mandatory education can be enough to move a country from the positive child labour equilibrium to an equilibrium with no child labour rationalite limitee anticipations et travail des enfants ce memoire developpe un modele de chevauchement des generations ou la fecondite optimale du menage le travail des enfants et les decisions a propos de l education dependent des anticipations des parents ou de qu ils croient etre le rendement sur l education on montre qu il existe un eventail de revenus des parents pour lequel le taux de fecondite est eleve et les enfants participent au marche du travail et recoivent une education incomplete si un parent croit que le rendement sur l investissement en education est faible le fait d entrer sur le marche du travail reduit la capacite de l enfant a accumuler du capital humain et donc le fait de l envoyer sur le marche du travail est suffisant pour s assurer que les anticipations pessimistes du parent se realisent on montre qu une intervention ponctuelle de politique publique a un moment donne comme bannir le travail des enfants ou imposer l education obligatoire peut suffire pour deplacer un pays d un equilibre avec travail des enfants vers un equilibre sans travail des enfants

determinants of residential space heating expenditures in great britain in great britain several policy measures have been implemented in order to increase energy efficiency and reduce carbon emissions in the domestic sector this could for example be achieved by improving space heating efficiency and thus decreasing heating expenditure however in order to efficiently design and implement such policy measures a better understanding of the determinants affecting heating expenditure is needed in this paper we examine the following determinants socio economic factors building characteristics heating technologies and weather conditions in contrast to most other studies we use panel data to investigate household demand for heating in great britain our data sample is the result of an annual set of interviews with more than 5000 households starting in 1991 and ending in 2005 the sample represents a total of 64 000 observations over the fifteen year period our aim is to derive price and income elasticities both for britain as a whole and for different types of household our results suggest that differences exist between owner occupied and renter households these households react differently to changes in income and prices our results also imply that a number of socio economic criteria have a significant influence on heating expenditure independently of the fuel used for heating understanding the impacts of different factors on heating expenditure and impact differences between types of household is helpful in designing target oriented policy measures

a bibliometric review energy consumption and greenhouse gas emissions in the residential sector residential sector has been one key sector for reducing its greenhouse gas emissions due to its significant contribution to global warming researchers in different countries have studied household energy consumption patterns and greenhouse gas emissions in order to promote low carbon lifestyles however few review papers have been published in this regard leading to a lack of systematic understanding on the related research achievements hence by using a bibliometric approach this paper aims to review the existing literature and examine the evolution of such a field so that the research trends can be uncovered including popular research methods citation analysis is performed to assess the influence of most productive journals countries territories and authors network analysis is also conducted to evaluate the relationship among different countries territories authors and keywords research outcomes of this paper present a comprehensive research picture on residential energy consumption and corresponding greenhouse gas emissions ree related papers published from 1997 to 2016 the most productive journals countries territories authors are also analyzed based on citation analysis and network analysis in addition results also revealed that behavioral analysis input output analysis life cycle assessment and cost benefit analysis are the most commonly used methods in this field results obtained from this study can provide valuable information for researchers interested in the ree related field

parental choice of human capital investment abstract in this paper we present a model in which parents make schooling decisions for their children we compare two educational regimes public and private education in the private education regime all human capital investment decisions are made by individuals under public education the government uses income tax revenue to finance one input to schooling in the private education regime cycles may occur even though there are constant returns to scale in the augmentable factors in the public education regime there are no cycles but poverty traps may occur

mortality fertility and child labor abstract we examine the persistence of child labor when adult mortality is endogenous children provide current consumption through child labor and future consumption via an informal social security arrangement poorer parents unable to invest much in their health face higher mortality and send their children to work instead of school fertility decisions exacerbate the problem as parents substitute towards quantity investment in children

what is the best age to enter the labor market in brazil today abstract this study is an attempt to measure the effects of entering the brazilian labor market at an early age on wages earned as an adult in a previous study using a pooled data cross section 1988 and 1996 the conclusion was reached that the effect of entering the labor market at an early age is negative for those who begin to work early in life but it becomes positive for those who start working between the age of 12 and 14 we used a pooled data cross section 2001 2009 and 2011 and found evidence that this age is much higher today meaning that earnings continue to grow as people enter the labor market after the age of 14 we also found a threshold effect in returns to education with a magnitude that increases as people enter the labor market at older ages

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

what factors drive inequalities in carbon tax incidence decomposing socioeconomic inequalities in carbon tax incidence in ireland abstract carbon taxes increase the cost of necessary household energy expenditures in many developed countries carbon taxes are regressive as they comprise a greater proportion of a poorer household s income certain socioeconomic groups are more negatively affected by these impacts than others while inequality of incidence by income group has received great attention in the literature a gap exists to quantify the inequality associated with socioeconomic characteristics this information is policy relevant as it may inform the most effective means to offset negative welfare impacts through changes to taxes and or social transfers this paper provides this contribution first the inequality of carbon tax incidence across the income spectrum is quantified using the concentration index methodology a subsequent multivariate decomposition quantifies the contribution each socioeconomic factor makes towards this inequality of incidence this is carried out for electricity motor fuel and all other home fuels to elicit variation of socioeconomic incidence by source while income contributes a great deal towards inequality of incidence for other home fuels other socioeconomic characteristics are the primary determinants of electricity and motor fuel related carbon tax incidence the relative importance of each characteristic in determining regressive impacts is quantified and this varies by carbon tax source

the global child labor problem the problem of child labor has moved from a matter of regional and national concern to one of international debate and possible global persuasion and policy intervention in crafting policy for mitigating this enormous problem of our times it is important to start with a proper theoretical and empirical understanding of the phenomenon what gives rise to child labor and what are its consequences what interventions might end child labor without hurting children a well meaning but poorly designed policy can exacerbate the poverty in which these laboring children live even leading to starvation the article surveys the large and rapidly growing literature on this subject focusing mainly on the new literature based on modern economic theory and econometrics it also looks at some of the broad policy implications of these new findings with the objective of contributing to better informed discussion and policy design

the bare necessities how much household carbon do we really need the consumption patterns of western nations are generally deemed to be unsustainable yet there is little attempt to restrain either material throughput or income growth nonetheless in the face of the need to make deep cuts in carbon emissions for instance consumption restraint may be a perfectly legitimate response this paper explores the potential for a reduced consumption scenario in the uk constructed by assuming that households achieve a specific minimum income standard which is deemed to provide a decent life for each household type the minimum income standards are taken from a recent study for the joseph rowntree foundation and include not only subsistence commodities such as food warmth and shelter but also the means to participate effectively in society the joseph rowntree foundation study produced detailed household expenditure budgets for these income standards the paper uses an environmentally extended quasi multi regional input output model to estimate the greenhouse gas ghg emissions required in the production and distribution of all goods and services purchased according to these budgets our results show that average household ghg emissions in the uk would be around 37 lower in the reduced consumption scenario than they are currently we explore several implications of these findings including the need to change social norms around consumption the need for investment to improve the thermal performance of homes and the need to develop new transport infrastructures we also address the potential to reduce emissions below the level achieved in this scenario and discuss the implications for policy

the impact of household consumption patterns on emissions in spain abstract the aim of this paper is to analyse the relationship between household consumption patterns and pollution in the spanish economy the analysis was carried using a social accounting matrix sam for the spanish economy prepared for 1999 taking the final demand of households as the exogenous account in the sam framework and combining this with the information provided by the household budget continuous survey on income and consumption ine 1999 we analyse the pollution produced by both the economy and households in order to satisfy consumption requirements we also consider the effects of income inequality on expenditure levels establishing a link between income level consumption patterns propensity to consume and co2 emissions

statistical models for zero expenditures in household budgets household budget surveys are an important source of data on consumer s expenditure not just for individual consumers but also for estimating national aggregates however it is a widespread finding that for certain commodities most notably tobacco and alcohol the estimate from the household survey falls short of the known consumption total calculated with some confidence from data on production imports exports and excise duties for example in the british family expenditure survey with which we shall largely be concerned total tobacco expenditure was underestimated in 1976 by 21 percent see kemsley redpath and holmes 1980 p 51 much of this understatement together with that on alcohol is thought to occur because of the design of the survey which excludes many persons amongst whom consumption of such items is thought to be atypically high e g prisoners hoteliers and their residents merchant seamen even so the possibility remains that some of the understatement is due to various types of misreporting by households included in the survey in this paper we consider a model in which the standard tobit specification tobin 1958 is supplemented by the operation of a simple binary censor the tobit model is essentially a linear regression model in which non positive observations of the dependent variable are replaced by zero we take this specification as our starting point but add a second censoring process that randomly replaces a fraction of the observations generated by the tobit model bv zeroes the combined model can serve as a representation of several types of

the impact of socioeconomic characteristics on co2 emissions associated with urban mobility inequality across individuals abstract concerns about the unequal distribution of greenhouse gas emissions attributable to mobility are gaining increasing attention in scholarly analyses as well as in the public policy arena the factors influencing the emissions of individuals are largely undocumented but they are assumed to be the same for all be they low or high emitters we use a household travel survey conducted in the metropolitan area of barcelona to differentiate the factors that result in different rates of emission it shows that the top 10 of emitters produce 49 of total emissions while non daily emitters make up 38 5 of the sample we adopt a quantile regression approach which reveals significant socioeconomic differences between groups of emitters gender income and home municipality type are influential in accounting for co 2 emissions for all groups educational level appears to be less significant and occupation shows no significance at all the study confirms the ineffective nature of toll policy design in the area overall socioeconomic factors have different impacts on different emitting groups but these characteristics do not impact equally across all the population quantile regression using mobility survey data gathered from various cities would provide useful evidence for improving the design of urban mobility policies

impacts of household income change on co2 emissions an empirical analysis of china abstract sustained increase in chinese household income has exerted positive impact on the consumption of goods and services this paper aims to analyze the unequal impacts of household consumption across different income households on the whole co2 emissions by utilizing a semi closed input output model and hypothetical extraction method the semi closed input output model moves household consumption activities into the intermediate use along with dividing urban and rural households to several groups by their income levels and the hypothetical extraction method hem is used to estimate the reductions of co2 emissions relative to total emissions after extracting the consumption of each household group the results show that 1 the impact on co2 emissions generated by urban households consumption are 1 8 times as much as that of rural ones 2 excluding consumption of higher income households from the economy would cause greater co2 emission reductions than lower ones specifically urban highest income households have the most relative reductions of co2 emissions which are 12 2 in 2007 and 13 8 in 2012 while for rural highest income households are 5 1 in 2007 and 5 1 in 2012 and urban and rural highest income households are respectively 3 8 and 1 8 times on the relative reductions of the lowest income ones 3 the relative reductions of household co2 emissions from food sectors is the most while from residence sectors is the least based on the above conclusions this paper puts forward consumption based policy implications

interactions in swiss households energy demand a holistic approach abstract this article analyzes the interactions and possible trade offs between direct energy consumption and embodied energy requirement of households in switzerland in order to assess the net impacts of standard energy policies focusing exclusively on direct energy use direct and embodied energy demand of swiss households are estimated by combining consumption data of a national expenditure survey with data on energy intensity from life cycle analysis using a system of equations and an instrumental variable approach we find that both domains are driven by same determinants but that there is no evidence for significant substitution between them we also find an increasing effect of income on both domains with particularly important effects on embodied energy from a policy perspective our findings highlight a concern that economic growth could bring about an increasing global energy demand through energy requirement for non energy commodities however the wide spread policies targeting direct energy are unlikely to cause a substantial shift in household consumption to embodied energy

household choices of child labor and schooling a simple model with application to brazil this paper argues that conflicting results from previous literature related to the effect of economic conditions on child labor derive from different income and substitution effects implicit in different types of income variation we use agricultural shocks to local economic activity in brazil coffee production to distinguish between increases in household income and increases in the opportunity cost of time results show that higher household wealth is associated with lower child labor and higher schooling nevertheless temporary increases in local economic activity are associated with higher child labor and lower schooling particularly for children with poor economic backgrounds

is there a child labor trap intergenerational persistence of child labor in brazil this article examines the intergenerational persistence of child labor empirically by looking at household survey data from brazil previous empirical work on child labor has focused primarily on isolating the determinants of child labor using survey data we take a different approach by asking does the child labor status of parents affect the child labor incidence of their children we look at this question in two ways our working assumption is that financial need creates this generational link but we also ask if there exists an intergenerational link over and above that which is transmitted through the production of income perhaps through norms we find strong evidence that this link exists and that it appears to persist even when income is held constant moreover we find that children who did not work as child laborers command higher salaries later in life which suggests that the potential human capital gains through apprenticeship as children are outweighed by the human capital gains children receive through schooling excerpt

some notes on how land title affects child labor secure property rights are considered a key determinant of economic development however evaluation of the causal effects of land titling is a difficult task since 2004 a program called papel passado has issued titles to more than over 85 000 families and has the goal to reach 750 000 this paper examines the direct impact of securing a property title on child labor force participation this study uses a comparison between two close and similar communities in the city of osasco case the key point of this case is that some units participate in the program and others do not estimates generated using difference in difference econometric technique suggest that titling results in a substantial decrease in child labor force participation for the families that received the title compared with the others this findings are relevant for future policy tools for dealing with informality and how it affects economic growth

will trade sanctions reduce child labour the role of credit markets abstract we examine the interaction between credit markets trade sanctions and the incidence of child labour in a two good two period model with unequally wealthy households both poverty and poor education quality inter alia are important determinants of child labour the incidence of child labour decreases as we move from the case of borrowing constraints to the case in which poor households can borrow freely from rich ones and then to the case of perfect international credit markets trade sanctions can increase child labour especially among poor households a possibility that decreases as their access to credit improves

to each their own the greenhouse gas impacts of intra household sharing in different urban zones abstract decreasing household size is a global trend driven by urbanization and multiple other socioeconomic trends going solo poses a great environmental challenge as the possibility to benefit from scale economies in consumption and its greenhouse gas impacts is not taken advantage of in other words understanding of intra household sharing patterns of different consumption categories is increasingly important in climate change mitigation this paper explores the relationship between household sizes urban structures and greenhouse gas impacts of lifestyles when urban areas grow outwards the household sizes also grow as a result of this the increase in intra household sharing seems to alleviate the negative ghg implications of urban sprawl which is highly logical but yet not comprehended thus the rise of collaborative consumption offers potential to reduce the greenhouse gas emissions of solo dwellers and compensate for the lower intra household sharing with inter household sharing

mechanisms explaining the impact of economic inequality on environmental deterioration abstract rising economic inequality often considered intrinsically harmful is increasingly being viewed as having a number of secondary impacts as well including impacts on health and economic growth the ongoing nature of today s environmental crisis also raises questions about inequality s role in environmental deterioration despite the large number of papers that have been written on this topic no theoretical or empirical consensus presently exists firstly our article identifies that authors conclusions in this area depend on their hypotheses regarding 1 the relationship between individual income and individual environmental pressure 2 the impact of inequality on the social norms that influence individual environmental pressure 3 the interests that social groups have in degrading or protecting the environment 4 how these interests play out in terms of political demands and 5 how these political demands translate into political decisions secondly the study shows that despite enabling a general test of the causal relationship between inequality and the environment the empirical methods utilised do not account for the full range of theoretical mechanisms in play hence the suggestion that a research programme be launched to conduct empirical studies of the five aforementioned hypotheses by applying a recursive approach

child labor and household land holding theory and empirical evidence from zimbabwe summary the relationship between rural household productive assets and child labor in developing countries is complex some empirical evidence shows that child labor tends to increase as land holding increases or there is an inverted u shaped curve relationship between the probability of putting children to work and land holding this paper shows that the relationship between use of children as laborers and land holding is nuanced child labor generally decreases as per capita land holding increases but there can be an upward bump in the relationship between child labor and landholding near the middle of the range of land per capita the bump can be explained theoretically by the relationship between the marginal productivity of a child worker on the farm and the marginal value placed on his her education at different levels of wealth this pattern is repeated in three surveys conducted in zimbabwe in 2001 2007 8 and 2010 11 from the perspective of policy making the policy maker should be alerted that the programs to promote school retention should not necessarily focus only on the poorest households in rural areas there is a high probability that middle wealth households put their children to work and this probability may change by some other factors such as gender of child and agro ecological conditions

opportunity inequality and the intergenerational transmission of child labour this paper presents a model in which opportunity differences within society result in child labour where opportunity is broadly defined but can include school quality access to higher paying jobs access to information about the returns to education and actual discrimination if opportunity differences exist child labour and poverty are shown to be symptomatic of this underlying socioeconomic condition it is then shown that policies that ban child labour and or introduce compulsory education laws can actually reduce dynastic welfare increase poverty and further exacerbate income inequality within society because they treat the symptom rather than the disease the lack of opportunity

personal carbon trading a critical survey part 1 equity abstract in recent years there has been considerable discussion within uk climate policy circles regarding the appropriateness of personal carbon trading as an instrument for greenhouse gas emission reduction this paper is the first in a two part survey of personal carbon trading pct the term used here to describe proposed sub national greenhouse gas emission trading schemes under which at least some emissions rights are allocated to and surrendered by individuals after introducing the various proposed pct schemes the paper compares in terms of equity the two most discussed pct schemes with two alternative emission trading schemes and a carbon tax the papers two key findings are as follows first there are strong arguments that the equal per capita allocation proposed under some instruments is not completely fair second the five instruments compared can be equivalent in terms of their equity along with equity efficiency and effectiveness make up three key criteria for comparing environmental policy instruments as pct has no advantage in terms of equity the paper concludes that any case for pct will depend on it having advantages in terms of efficiency and or effectiveness whether pct has such advantages is explored in part 2

what is a fair co2 tax increase on fair emission reductions in the transport sector we examine how individual preferences for fair reductions of carbon dioxide co2 emissions affect the support for increases in the co2 tax on gasoline and diesel we assume that people not only care about their own material welfare but also have preferences for fairness in policy design and we explore the implications using original data from a mail questionnaire sent to a representative sample of the swedish population the main result is that fairness in policy design does matter those respondents who adhere to a fairness principle tend to be relatively more positive to increases in the co2 tax one possible explanation for this result is that there is a relatively high degree of reciprocity regarding the origin of emissions and the fairness regarding who should bear the burden of co2 reductions via a split sample analysis we also find that the relative importance of fairness principles is dependent upon whether one uses a car often or not this sheds light on the potential goal conflict between the importance of fairness principles and self interest in the form of a need for private car transportation

welfare dynamics in pakistan and ethiopia does the estimation method matter identifying household level welfare dynamics and associated dynamic poverty trap thresholds can have important implications for the targeting of poverty reduction policies the small existing empirical microeconomic literature has found evidence both for and against poverty traps using household panel data from rural pakistan and ethiopia this article examines whether these different results are likely driven by differences in estimation methods or whether they reflect actual differences across settings it applies the estimation methods from the existing literature to the same two datasets and also proposes a novel semiparametric panel data estimator that combines the advantages of the previous fully parametric and nonparametric approaches the results suggest that absent any dynamic poverty trap thresholds the effect of using different estimation methods is secondary having a small influence on the estimated long term level of household well being but not the identification of multiple dynamic welfar

why does child labor persist with declining poverty we develop a dynamic overlapping generations model to highlight the role of income inequality in explaining the persistence of child labor under declining poverty differential investment in two forms of human capital schooling and health in the presence of inequality gives rise to a nonconvergent income distribution in the steady state characterized by multiple steady states of relative income with varying levels of education health and child labor the child labor trap thus generated is shown to preserve itself despite rising per capita income policy recommendations include public provision of education targeted toward reducing schooling costs for the poor or raising the efficacy of public health infrastructure jel i1 j2 o1 o2

quantifying the global and distributional aspects of american household carbon footprint abstract analysis of household consumption and its environmental impact remains one of the most important topics in sustainability research nevertheless much past and recent work has focused on domestic national averages neglecting both the growing importance of international trade on household carbon footprint and the variation between households of different income levels and demographics using consumer expenditure surveys and multi country life cycle assessment techniques this paper analyzes the global and distributional aspects of american household carbon footprint we find that due to recently increased international trade 30 of total us household co 2 impact in 2004 occurred outside the us further households vary considerably in their co 2 responsibilities at least a factor of ten difference exists between low and high impact households with total household income and expenditure being the best predictors of both domestic and international portions of the total co 2 impact the global location of emissions which cannot be calculated using standard input output analysis and the variation of household impacts with income have important ramifications for polices designed to lower consumer impacts on climate change such as carbon taxes the effectiveness and fairness of such policies hinges on a proper understanding of how income distributions rebound effects and international trade affect them
