activity choice labor allocation and forest use in malawi this article examines the determinants of activity choice affecting forest use among low income households in malawi data from three villages are used to estimate a system of household labor share equations for maize production forest employment and non forest employment a system estimation approach is used to identify factors influencing the competing and synergistic livelihood strategies which households undertake at the forest margin results from constrained maximum likelihood estimation indicate heightened incentives to degrade forests when returns to forest use are high factors reducing forest pressure include favorable returns to non forest employment secondary education of the household head and wealth

the crowding hypothesis and comparable worth although women s pay and occupational distribution have improved during the past few years it is still true that women earn considerably less than men and that their occupational distribution is substantially different because progress has been slow toward equality in the labor market some have called for a comparable worth policy proponents of this approach argue that occupational segregation contributes to the earnings disparity between women and men one theoretical justification for this position is the crowding hypothesis this paper first explains this theory and presents a method used to test its principal hypothesis it then describes an extension of this design for estimating the phenomenon that comparable worth policies address empirical studies conducted in this area are viewed and new findings are presented finally limitations of this analysis are discussed i introduction

is it possible to improve environmental quality without reducing economic growth evidence from the qatar economy abstract in line with the priorities of the qatar national vision qnv 2030 and its principal pillars we examine in this paper the energy use economic growth nexus for qatar during the period 1970 2014 using recent development in both unit roots and ardl bounds testing approach with structural breaks we found strong evidence for the growth hypothesis this result indicates that the qatari policymakers should recognize that energy conservation policies will have adverse effects on economic growth and therefore alternative means must be undertaken to preserve the environment this paper presents and discusses a detailed economic energy and environmental policies that can help qatari policymakers in achieving the objective of balance between economic growth and environment quality

impact of income on nutrient intakes implications for undernourishment and obesity the relationship between income and nutrient intake is explored nonparametric panel and quantile regressions are used engle curves for calories fat and protein are approximately linear in logs with carbohydrate intakes exhibiting diminishing elasticities as incomes increase elasticities range from 0 10 to 0 25 with fat having the highest elasticities countries in higher quantiles have lower elasticities than those in lower quantiles results predict significant cumulative increases in calorie consumption which are increasingly composed of fats though policies aimed at poverty alleviation and economic growth may assuage hunger and malnutrition they may also exacerbate problems associated with obesity

sex segregation within occupations do the paychecks and career prospects of men and women differ because of rational optimizing decisions made by men and women given their respective skills experiences home responsibilities and intentions regarding future work and family activities the human capital model coherent logical and internally consistent has a certain elegance to it nevertheless empirically it cannot explain the sex composition of jobs in lines of work pursued by both men and women the results reported below are more consistent with the notion that employers statistically discriminate that is they reserve some jobs for men and others for women based on their perceptions of the average traits of the two groups however our results also call into question the assumption that statistical discrimination is merely an optimal decisionmaking strategy under conditions of uncertainty we summarize below our recent research on determinants of the sex composition of jobs in mixed occupations that research is based on data on staffing patterns job requirements and personnel policies collected by the u s employment service in over 400 california establishments between 1959 and 1979 details on sample representativeness procedures of data collection and the like can be found in our 1984 and 1986 papers

poverty and environmental degradation in the nicaraguan hillsides abstract this article questions the assumption of poverty as a major cause of environmental degradation examining five environmentally harmful natural resource management practices in the nicaraguan hillsides it shows that the immediate agents of environmental degradation are the nonpoor farmers not the poorest it argues that to analyze the causal links between poverty and environment a distinction between poverty as a state of deprivation and poverty as a relational phenomenon is necessary finally the article warns that the often strategic reference to poverty as the major cause of environmental degradation made by nonpoor and poor farmers may lead to negative environmental impacts

what happens to diet and child health when migration splits households evidence from a migration lottery program the impact of migration on food security and child health is likely to differ depending on whether children themselves migrate or whether they remain behind while other household members migrate however existing studies have not been able to examine how impacts differ in these two scenarios because parallel data are required for both the sending and receiving country moreover self selection into migration makes unbiased estimation of either impact difficult we overcome these problems by using a unique survey of tongan households that applied to migrate to new zealand through a migrant quota which selects households through a random ballot this survey covers both migrant children in new zealand and non migrant children in tonga with the migration policy rules providing a source of exogenous variation for identifying impacts our estimates of short run impacts show that diets diverge upon migration children who migrate experience improvements while diets worsen for children who remain there is also suggestive evidence of a divergence in health outcomes with increases in weight for age and height for age found for migrant children and decreases found for children who remain behind while other household members migrate

natural resource management and household well being the case of posaf ii in nicaragua summary measuring the impact of natural resource programs is a key element in the formulation and implementation of policies designed to promote farm income while enhancing the quality of the surrounding environment in this paper we analyze the economic impact of natural resource technologies delivered by the socio environmental and forestry development program ii posaf ii in nicaragua we use cross sectional data for 1 483 households from 212 treated and control communities results obtained from propensity score matching psm ordinary least squares ols weighted least squares regression wls based on psm and instrumental variables iv regression indicate that posaf ii has had a positive impact on the total value of agricultural production of beneficiary farmers an internal rate of return analysis supports the hypothesis that increasing household income while encouraging the sustainable use of natural resources through the implementation of suitable management programs can be complementary development objectives

brazilian policies that encourage deforestation in the amazon this paper shows that general tax policies special tax incentives the rules of land allocation and the agricultural credit system all accelerate deforestation in the amazon these policies increase the size of land holdings and reduce the chances of the poor to become farmers the following are the key provisions i the virtual exemption of agricultural income from income taxation makes agriculture a tax shelter ii rules of public land allocation provide incentives for deforestation because the rules used in determining the security of a claim and its land area encourage land clearing iii the progressive land tax contains provisions that encourage the conversion of forest to crop land or pasture iv the tax credit scheme aimed toward corporate livestock ranches subsidizes inefficient ranches established on cleared forest land and v subsidized credit is available for sudam approved ranches

the labour market impact of body weight in china a semiparametric analysis while a positive wage effect of body mass index bmi is widely observed in low income developing countries a negative wage effect of bmi is often observed in high income developed countries to fill the gap between these previous findings we investigate the relationship between body weight and wages in transition economies we focus on china whose rapid economic growth of the 1990s was followed by a rapid increase in overweight and obesity while still experiencing significant food insecurity and underweight we first use several parametric regression strategies to obtain a consistent estimate of the wage effects of weight second we adopt a semiparametric partially linear model that allows for endogeneity of weight parametric regressions provide mixed results and the sign and magnitude of their estimates are sensitive to the choice of samples and regression strategies semiparametric estimates provide evidence of a wage penalty for very heavy and thin persons among both men and women the wage pena

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

lifetime earnings and the vietnam era draft lottery evidence from social security administrative records errata the randomly assigned risk of induction generated by the draft lottery is used to construct estimates of the effect of veteran status on civilian earnings these estimates are not biased by the fact that certain types of men are more likely than others to service in the military social security administrative records indicate that in the early 1980s long after their service in vietnam had ended the earnings of white veterans were approximately 15 percent less than the earnings of comparable nonveterans copyright 1990 by american economic association

fixing women s wages the effectiveness of comparable worth policies the author discusses some problems that can prevent comparable worth legislation from achieving meaningful gender wage equity which she defines as the elimination of gender as a factor in wage setting she then tests the comparable worth policies of two canadian provinces against the same set of job content data from a 1988 survey of health care workers whereas manitoba s comparable worth policy she finds would achieve gender wage equity if applied to this set of jobs ontario s would not and would even result in new and capricious instances of inequity she argues that continual scrutiny including comparative analysis of comparable worth policies is needed not only in order to identify the most effective policy designs but also to guard against efforts to undercut legislation through manipulation of implementation procedures

heterogeneous preferences compensating wage differentials and comparable worth this paper sets up a general equilibrium model of a world of heterogeneous jobs and heterogeneous tastes and uses the model to i analyze the effects of employer discrimination and ii predict the likely consequences of requiring equal pay for jobs of comparable worth it shows that employment of both women and men is likely to fall as a result of comparable worth it also shows that when individuals tastes are heterogeneous neither comparable worth nor the simple model of compensating differentials on which it is based provides useful insights into wage determination in particular when tastes are heterogeneous there is no reason to expect equal pay for jobs of comparable worth even in the absence of employer discrimination

extended families and child well being studies of household behavior have established the distribution of resources among household members predicts spending and savings patterns however there is a paucity of evidence on the relationship between the well being of individual family members and the distribution of resources within an extended family including non co resident family members given the central role the family plays in many models of economic behavior this is an important gap in the literature using rich longitudinal survey data from the indonesia family life survey ifls evidence is presented on the relationship between three measures of health and education related human capital of children and the distribution of resources among extended family members ifls is ideally suited for this research since the survey collects detailed information about income and wealth from both coresident and non co resident family members the empirical model is founded on a natural extension of the collective model of household decision making chiappori 1988 1992 to the extended family the model is particularly appealing in this context because it places few restrictions on preferences of individual family members and does not specify a specific bargaining mechanism that underlies negotiations the collective model yields empirical tests of whether the behavior of family members is pareto efficient a special case of the model allows all family members to be completely altruistic which is observationally equivalent to a unitary model of family behavior that special case is rejected by the data however the restrictions of the efficient model are not rejected indicating that non co resident family members are able to co ordinate allocation decisions with respect to child human capital investments in such a way as to make no family member better off without another member being worse off

which hedonic models can we trust to recover the marginal willingness to pay for environmental amenities abstract the hedonic property value model is among our foremost tools for evaluating the economic consequences of policies that target the supply of local public goods environmental services and urban amenities we design a theoretically consistent and empirically realistic monte carlo study of whether omitted variables seriously undermine the method s ability to accurately identify economic values our results suggest that large gains in accuracy can be realized by moving from the standard linear specifications for the price function to a more flexible framework that uses a combination of spatial fixed effects quasi experimental identification and temporal controls for housing market adjustment

inequality as a cause of environmental degradation abstract this paper advances two hypotheses first the extent of an environmentally degrading economic activity is a function of the balance of power between the winners who derive net benefits from the activity and the losers who bear net costs second greater inequalities of power and wealth lead all else equal to more environmental degradation

the long run labor market consequences of civil war evidence from the shining path in peru abstractthis study exploits district level variation in the timing and intensity of civil war violence to investigate whether early life exposure to civil wars affects labor market outcomes later in life in particular we examine the impacts of armed conflict in peru a country that experienced the actions of a tenacious brutally effective war machine the shining path between 1980 and 1995 this study finds that the most sensitive period to early life exposure to civil war violence is the first 36 months of life a 1 standard deviation increase in civil war exposure leads to a 5 fall in adult monthly earnings 3 5 reduction in the probability of working in formal jobs and 6 reduction in the probability of working in large firms substantial heterogeneity in the earnings impacts emerges when considering variation in the type of civil war violence overall forced disappearances emerge as the most hurtful measure of violence in the long run sexual violations disproportionately affected the wages of

civil conflict and human capital accumulation the long term effects of political violence in peru this paper provides empirical evidence of the persistent effect of exposure to political violence on human capital accumulation i exploit the variation in conflict location and birth cohorts to identify the long and short term effects of the civil war on educational attainment conditional on being exposed to violence the average person accumulates 0 31 less years of education as an adult in the short term the effects are stronger than in the long run these results hold when comparing children within the same household further exposure to violence during early childhood leads to permanent losses i also explore the potential causal mechanisms

human development means and ends from growth to basic needs sometimes the change in the fashions of thinking about development appears like a comedy of errors a lurching from one fad to another economic growth employment creation jobs and justice redistribution with growth basic needs bottom up development participatory development sustainable development market friendly development liberation liberalisation human development thus goes the carousel of the slogans but this would not be a correct record there has been an evolution in our thinking about development both internal logic and new evidence have led to the revision of our views previous and partly discarded approaches have taught us much that is still valuable and our current approach will surely be subject to criticisms a brief survey of the evolution of our thinking may be helpful the discussion started in the 1950s influenced by arthur lewis 1955 and others who emphasised economic growth as the key to poverty eradication even at this early stage sensible economists and development planners were quite clear in spite of what is now often said in caricature of past thought that economic growth is not an end in itself but a performance test of development arthur lewis defined the purpose of development as widening our range of choice exactly as the human development reports of the united nations development programme do today three justifications were given for the emphasis on growth as the principal performance test one justification assumed that through market forces such as the rising demand for labour rising productivity rising wages lower prices of the goods bought by the people economic growth would spread its benefits widely and speedily and that these benefits are best achieved through growth even in the early days some sceptics said that growth is not necessarily so benign they maintained that in certain conditions such as increasing returns restrictions to entry monopoly power unequal distribution of income and assets growth gives to those who already have it tends to concentrate income and wealth in the hands of the few this is where the second assumption came in it was that governments especially democratic ones are concerned with the fate of the poor therefore progressive taxation social services and other government interventions would

poverty and environmental degradation a review and analysis of the nexus abstract there is much controversy surrounding the poverty environmental degradation nexus the predominant school of thought argues that poverty is a major cause of environmental degradation and if policy makers want to address environmental issues then they must first address the poverty problem another school of thought argues that a direct link between poverty and environmental degradation is too simplistic and the nexus is governed by a complex web of factors in this paper a formal structure for analyzing the complex web of factors is formulated and used to review the existing literature on the links between poverty and the degradation of four natural resource sectors the analysis highlights the important role institutional and market failure in encouraging agents from various income groups to exhibit unsustainable activities which in turn forces some of the agents to fall into poverty another important factor is the role of conflicts between different agents income groups in the povertyenvironmental degradation nexus the analysis also highlights the presence of feedback loops between environmental degradation and poverty

does air pollution aggravate income inequality in china an empirical analysis based on the view of health abstract given the rapid development of the chinese economy especially its accelerated urbanization air pollution and income inequality as two of the most important global issues have also become hot topics in china however limited attention has been devoted to understanding their joint evolution in the literature in this study we thus investigate the relationship between them using a multi level nested data model which enables us to estimate the long run distribution effect of air pollution on individuals of different socioeconomic statuses based on china s city level pm2 5 emissions and individual level income we further examine the mechanisms behind the evolution using a 3sls model the estimation results reveal that the increase in air pollution concentration has short term positive production effects and long term negative impacts on individual income and will exacerbate the income inequality across socioeconomic statuses individuals of lower socioeconomic status have disadvantages in achieving efficient avoiding knowledge and measures the results of 3sls model confirm the existence of the health channel through which air pollution exerts influence on income inequality these results provide a roadmap for policymakers first a comprehensive assessment of the health burden distribution from air pollution on individuals of different socioeconomic statuses should be considered for environmental policymaking second the regional disparities and differences among income groups should also be considered during this process third equal access to basic public services should be the primary target of environmental regulations moreover compensation and assistance for the health issues caused by environmental pollution could be an important supplement to these regulations future study could do further analysis of the specific level of health burden due to different types of pollutants and their relationship with income inequality

comparable worth limited coverage and the exacerbation of inequality citing relevant judicial decisions the author argues that any application of the comparable worth remedy for gender discrimination is likely to cover only certain groups of workers most likely to be covered are women who work for governmental or large private employers in female dominated jobs and least likely to be covered are women who work for small private employers the implementation of comparable worth would cause the wages of noncovered workers to fall relative to those of covered workers and they might even fall absolutely an analysis of 1979 current population survey data suggests that the women most likely to gain from comparable worth are fewer in number better paid and subjected to no greater discrimination than the women most likely to lose

economic conditions early in life and individual mortality this paper analyzes the effect of economic conditions early in life on the individual mortality rate later in life using business cycle conditions early in life as an exogenous indicator we have individual data records from dutch registers of birth marriage and death certificates covering an observation window of unprecedented size 1812 2000 these are merged with historical data on macro economic and health indicators we correct for secular changes over time and other mortality determinants we nonparametrically compare those born in a recession to those born in the preceding boom and we estimate duration models where the individual s mortality rate depends on current conditions conditions early in life age individual characteristics including individual socio economic indicators and interaction terms the results indicate a significant negative effect of economic conditions early in life on individual mortality rates at all ages

village banking and maternal and child health evidence from ecuador and honduras abstract many microcredit institutions bundle credit with health education or other programs this paper reviews arguments on such tie ins and concludes that net benefits are possible but requires empirical testing quasi experimental data from project hope s health banks and credit only village banks are then examined the paper presents evidence that health practices do not improve automatically with greater wealth in honduras results show that health bank participation is robustly associated with reduced subsequent conditional child diarrhea probability but in no specification does credit only bank participation have this effect in ecuador results suggest a larger effect of credit only banks in both countries health bank participation significantly raises subsequent healthcare over credit only participation and at least reduces the tendency to switch from breast feeding to bottle feeding as income rises effects on expenditures are ambiguous there is no clear link between tie ins and bank performance

the economic relevance of sustainable agroforestry practices an empirical analysis from tanzania abstract this paper investigates the economic relevance of sustainable behavior of agroforestry practices for smallholders using the example of firewood exploitation in rural tanzania three questions are addressed 1 to what extent do households behave sustainably regarding firewood extraction from agroforestry 2 which factors determine the likelihood of households practicing sustainable agroforestry 3 are sustainably behaving households better off in terms of income compared to households practicing unsustainable agroforestry the analysis is based on cross sectional data of 314 households a sustainability indicator shows that the share of sustainable households varies between 14 and 41 depending on the underlying wood growth rate the results of the logistic regression indicate that property rights regarding the ownership of agricultural land and environmental awareness increase the likelihood of sustainable firewood extraction empirical evidence from the quantile regression reveals that poorest households generate higher income if they extract firewood unsustainably the opposite is true for households of upper income percentiles thus the poor are likely to increase environmental degradation to generate more income causing a downward spiral of the poverty environment trap resulting in income losses in the long run households with a per capita income of 524 tzs or more manage their tree stocks sustainably

the environmental impact of poverty evidence from firewood collection in rural nepal abstract we investigate determinants of household firewood collection in rural nepal using 1995 96 and 2002 3 world bank living standards measurement survey lsms data we incorporate village fixed effects endogenous censoring measurement error in living standards and heterogeneous effects of different household assets we find no evidence in favor of the poverty environment hypothesis the evidence for the environmental kuznets curve depends on the precise measure of living standards and time period studied firewood collections fall with a transition to modern occupations and rise with increasing population and household division the local interhousehold collection externality is negligible indicating that policy interventions are justified only by ecological considerations or nonlocal spillovers

an experimental study of job evaluation and comparable worth the doctrine of comparable worth rests on an assumption that each job possesses an inherent worth independent of the market forces of supply and demand implementation of comparable worth further requires that inherentjob worth be measured with reasonable accuracy this paper reports the results of an experimental study of comparable worth three commercial job evaluation firms rated the same set of 27 jobs in an actual company statistical analysis of the experimental data indicates that the three evaluators differed in which job trait or constellation of traits they used to evaluate inherent job worth implying that at least one of them failed to measure inherent job worth accurately these results suggest that any attempt to implement comparable worth may be quite sensitive to the evaluator chosen to measure job worth

towards a unified scheme for environmental and social protection learning from pes and cct experiences in developing countries environmental protection and poverty alleviation in the developing world are usually heralded as joint objectives however these two goals are often associated with different sectoral policy instruments while so called payments for environmental services pes are increasingly being promoted for environmental protection poverty alleviation is increasingly addressed by conditional cash transfers cct program these instruments although aimed to achieve distinct objectives have a number of similarities and challenges in their design and implementation phases this paper elaborates on these similarities and develops a unifying generic framework that is used to discuss the extent to which both approaches could be unified

quantifying the microeconomic effects of war using panel data evidence from nepal summary the extensive coverage of household surveys in conflict regions in recent decades has fueled a growing literature on the microeconomic effects of war in this paper we use a unique panel dataset to quantify the impact of the nepalese civil conflict on schooling attainment given longitudinal data we are able to directly estimate unobserved individual heterogeneity and thus address selective wartime displacement despite the widely held view that war is detrimental to human capital formation we find no effect of war intensity on schooling attainment once unobserved individual heterogeneity is accounted for we draw on supplementary data to explain our findings

assessing poverty deforestation links evidence from swat pakistan abstract this paper contributes to the debate on the links between poverty and forestry degradation the view that due to poverty and the meeting of subsistence needs the poor use natural resources more intensively and hence cause them to degrade using the case of the forest rich swat district pakistan the paper addresses the issue empirically historically and institutionally we do not find empirical support for the poverty environment nexus in that the poor and other income groups are equally resource dependent and also show that resource degradation is not associated with poverty our historical and institutional analyses provide alternative explanations for resource degradation selective and rotating ownership patterns starting with the 17th century provided limited incentive for resource conservation it also created tension between de jure and de facto owners that has persisted and is one source of forest degradation ill defined resource rights have also exacerbated the impacts of several other factors contributing to forest degradation which is compounded by poor management corruption and perverse incentives

health nutrition and economic development the relationship between health and economic development is explored focusing on nutrition based health indicators the spotlight is placed on the inter related feedbacks between the influence of health on productivity on one hand and the influence of income on health status on the other disentangling causality in these relationships has preoccupied much of the literature we evaluate different empirical strategies that have been adopted and assess the results there is now a body of evidence based on careful empirical studies that demonstrates a causal relationship between health and labor productivity there is also evidence that at least among the very poor additional income is spent on improved nutrition there are two issues that have received little attention although we argue they are likely to be very important first measurement of health is discussed in detail evidence is presented on how taking into account differences in the extent of measurement error is critical for interpreting the impact of health on wages the same theme emerges in studies of the effect of income on health specifically calorie intake the key role of non linearities in these relationships is highlighted and we demonstrate that a good deal of the variation in estimates of income elasticities of demand for calories can be ascribed to the role of measurement and functional form authors

income and the environment in rural india is there a poverty trap we study the relationships between rural income distributions and changes in environmental conditions in southern western and central india between 1994 95 and 2000 01 other than the relatively rich we find that all income strata benefit from an improved environment and intermediate expenditure households benefit more than the very poor in absolute terms higher median consumption expenditures and richness are estimated to increase environmental decline but we do not find a significant impact of income poverty on local environmental health the results do not support the poverty trap conjecture with environmental degradation driving expenditure reductions that promote offsetting aforestation which benefits the poor

roads out of poverty assessing the links between aid public investment growth and poverty reduction the authors develop a macroeconomic framework that captures links between aid public investment growth and poverty public investment is disaggregated into education infrastructure and health and affects both aggregate supply and demand dutch disease effects are captured by accounting for changes in the relative price of domestic goods the authors assess the impact of policy shocks on poverty by linking the model to a household survey they calibrate the model for ethiopia and simulate the changes in the allocation of aid and public investment the authors also calculate the amount by which foreign aid should increase to reach the poverty targets of the millennium development goals

the implementation process of comparable worth winners and losers this paper provides a unique opportunity to observe how a public policy affected the earnings of various interest groups at different stages of implementation specifically we examine how the earnings of women union members and supervisory and professional staff were affected by various proposed and implemented comparable worth pay plans in iowa we find that large relative gains to women in the original proposed plans were reduced as the process evolved as a result some of the original gains to women were redistributed to union members supervisors and professionals

foods and fads the welfare impacts of rising quinoa prices in peru abstract riding on a wave of interest in superfoods in rich countries quinoa went in less than a decade from being largely unknown outside of south america to being an upper class staple in the united states the united kingdom and elsewhere as a result concerned commentators suggested that the rising international demand for quinoa which tripled prices might have substantially harmed peruvian quinoa consumers we study the impacts of rising quinoa prices on the welfare of peruvian households our analysis suggests these fears are unwarranted a descriptive analysis shows that quinoa is a small part

african evidence on the relation of poverty time preference and the environment abstract it is typically argued in the economics literature that the poor operate with a higher rate of time preference than their wealthier counterparts the poor it is suggested have a higher rate of time preference because they are more concerned about present survival than they are about saving for the future such thinking is also central to the economic growth for environmental conservation and the poverty induced environmental degradation arguments according to these assertions wealth allows people to consider the future and invest in environmental conservation and poverty leaves people with no alternative but to exploit the environment so that they may feed their families today evidence from the food security and famine early warning fields suggests that households in many african contexts behave quite to the contrary during periods of food shortage poor households will often undertake extreme measures in the present including depriving the family of needed calories in order to preserve productive capital for the future such as a plough oxen or seed stock this evidence suggests that poor african households may in fact have very low rates of time preference this calls into question our general assumptions about discount rates for developing countries for which rates of time preference are a theoretical determinant

income productivity in china on the role of health this study provides empirical evidence regarding the income productivity of health human capital in china we appeal to concepts from human capital theory to support a basic model that treats health as a form of human capital in the income production process our model examines the economic return at the household level from the health of its individual members we estimate this with a longitudinal sample drawn from the china health and nutrition survey chns allowing us to exploit within variation in health and income to address possible unobservables biasing estimates of the impact of health on income in the simple cross sectional setting household income is strongly influenced by the health of its members particularly in rural areas these findings could have important implications for health and economic policy making aimed at reducing the long standing urban rural economic gap and more comprehensively insuring the rural population against health and economic risk

trends in the well being of american women 1970 1995 this paper examines the trends in the well being of american women over the last 25 years a time of significant changes in the relative economic status of women and in the labor market as a whole a broad range of indicators are considered to capture changes in women s well being in the family as well as in the labor market for virtually all age and education groups substantial evidence is obtained of rising gender equality in labor market outcomes notably labor force participation wages and occupational distributions broad evidence is also found of greater gender parity within married couple families as the housework time of husbands increased relative to wives and the relative wages of wives rose compared to their husbands however parallel to the recent evidence of the declining labor market position of lower skilled men there has been a similar deterioration in the economic status of less educated women especially high school dropouts their labor force participation rates and wages have risen at a much slower pace than those of more highly educated women while their incidence of single headship has increased much more rapidly these findings for less educated women serve to underscore the widening gap between more and less skilled americans of both sexes as well as to emphasize its broad dimensions

traps and sustainable development in rural areas a review summary the concept of a poverty trap commonly understood as a self reinforcing situation beneath an asset threshold has been very influential in describing the persistence of poverty and the relationship between poverty and sustainability although traps and the dynamics that lead to traps are defined and used differently in different disciplines the concept of a poverty trap has been most powerfully shaped by work in development economics this perspective is often constraining because as many studies show poverty arises from complex interactions between social and environmental factors that are rarely considered in development economics a more integrated understanding of poverty traps can help to understand the interrelations between persistent poverty and key social and ecological factors facilitating more effective development interventions the aim of this paper is to provide a critical appraisal of existing trap conceptualizations in different disciplines and to assess the characteristics and mechanisms that are used to explain poverty traps in rural contexts thereby broadening the traps concept to better account for social ecological interactions complementarities and tensions among different disciplinary perspectives on traps are identified and our results demonstrate that different definitions of traps share a set of common characteristics persistence undesirability and self reinforcement yet these minimum conditions are not sufficient to understand how trap dynamics arise from complex social ecological interactions to broaden the utility of the concept we propose a more social ecologically integrated definition of traps that includes four additional considerations cross scale interactions path dependencies the role of external drivers and social ecological diversity including these wider dimensions of trap dynamics would help to better account for the diverse social ecological feedbacks that produce and maintain poverty traps and could strengthen strategies to alleviate poverty in a more integrated way

under the weather health schooling and economic consequences of early life rainfall life in rural areas of developing countries is prone to many kinds of risk such as illness or mortality of household members crop or other income loss due to natural phenomena weather insect infestations or fire for example and civil conflict in addition to their contemporaneous effects the effects of certain types of shocks may still be felt many years or even decades later from a public policy standpoint it is particularly important to identify shocks that have large long run effects moreover the mechanics underlying the persistence of shocks may be of con siderable interest for example a health shock may have a long run effect simply because the health shock itself persists over time alternately the health shock may not directly affect long run outcomes but it could affect some other outcome such as educational attainment that helps determine long run well being in this paper we focus on shocks that occur at the very beginning of life we ask how sensi tive long run individual well being is to environmental conditions around the time of birth in particular we examine the effect of weather shocks around the time of birth on the adult health education and socioeconomic outcomes of indonesian women and men born between 1953 and 1974 in addition we attempt to shed light on the intervening pathways connecting early life rainfall to adult outcomes illuminating the roles of health and educational attainment in deter mining adult socioeconomic status this investigation has considerable data requirements it necessitates information on weather shocks experienced by individuals several decades earlier as well as detailed current informa tion on adult outcomes we use information in the indonesian family life surveys ifls on an individual s year and location of birth and link each individual in that survey to locality specific rainfall data for their birth year for individuals born in rural areas on whom we focus rainfall variation across space and time should generate corresponding variation in agricultural output and thus household income to deal with measurement error in the rainfall data we run instrumental variables regressions where variables for rainfall measured at slightly more distant rainfall stations serve as instruments for rainfall in the individual s birthplace and birth year we examine the impact of early life rainfall on a range of adult outcomes observed in 2000 we find that higher early life rainfall leads to improved health schooling and socioeconomic status for women women with 20 percent higher rainfall relative to normal local rainfall in their year and location of birth are 3 8 percentage points less likely to self report poor or very poor health they attain 0 57 centimeters greater height attain 0 22 more completed grades of

empirical regularities in the poverty environment relationship of rural households evidence from zimbabwe abstract analysis of rural households and environmental resources is beset by inadequate data especially in africa using purpose collected panel data from zimbabwe we demonstrate seven empirical regularities in the rural poverty environment relationship most important environmental resources make a significant contribution to average rural incomes poorer households also depend heavily on these resources which contribute c 40 to their incomes richer households however use greater quantities of environmental resources in total finally considerable differentiation exists in the economic characteristics of environmental goods these results demonstrate the considerable economic significance of environmental resources to rural households surveys which ignore them miscalculate rural incomes and welfare

the consequences of child soldiering abstract little is known about the impacts of military service on human capital and labor market outcomes due to an absence of data as well as sample selection recruits are self selected screened and selectively survive we examine the case of uganda where rebel recruitment methods provide exogenous variation in conscription economic and educational impacts are widespread and persistent schooling falls by nearly a year skilled employment halves and earnings drop by a third military service seems to be a poor substitute for schooling psychological distress is evident among those exposed to severe war violence and is not limited to ex combatants
