the effect of the food stamp program on nutrient intake i introduction one of the goals of the food stamp program as stated in the preamble of the law is to ensure that low income households have the opportunity to attain a nutritionally adequate diet previous economic studies evaluating the effects of food stamp income on nutrient intake have typically found a positive usually small correlation between the receipt of food stamps and nutrition two recent papers by devaney and moffitt 1991 and horton and campbell 1991 reach very positive conclusions concerning the effect of income in general papers from the nutrition literature generally find positive but weak and often insignificant effects of income on nutrition we employ information on two groups of low income people and find slightly different results for the two groups but very different results from many of the other studies for a sample of rural families taken from data from the rural income maintenance experiment we find almost no effect of food stamp income or evidence of selection bias 1 however for a sample of elderly people from the food stamp cashout project we find strong evidence that self selection into the food stamp program is highly correlated with attaining nutritional adequacy and that controlling for the self selection food stamp income and other income have a negative effect on nutrition we re examine the relationship between food stamp income and the nutrient intake of the poor and improve upon the existing literature in several important ways first it is possible that the positive correlation between the receipt of food stamps and nutrition is not a direct causal link but rather is the result of other factors affecting both for example in one of the samples examined in this paper only 50 percent of those eligible actually apply for and receive food stamps it could be the case that those who care more about nutrition are at the same time more likely to apply for and receive food stamps and more likely to maintain a nutritionally adequate diet these possible self selection problems can be disentangled from possible direct effects of food stamp income on nutrition using estimation procedures which correct for selection bias another issue which our research addresses is that the level of one nutrient may be correlated with the levels of other nutrients this may occur either because individuals who care about nutrition may be more likely to attain adequate levels of all nutrients or because combinations of nutrients occur naturally in foods we posit a multi equation model of the levels of nutrients and allow the disturbances in each equation to be correlated none of the previous studies considered this correlation finally we recognize the fact that above some level extra nutrients are superfluous if an individual has attained a nutritionally adequate diet then whether or not food stamp income allows him or her to consume more nutrients is irrelevant we are primarily interested in therefore whether or not an individual attains an adequate level of a nutrient rather than the absolute amount of a nutrient consumed in previous studies devaney and moffitt 1991 had addressed simultaneously the issues of selection bias and the superfluity of nutrients above some level the finding that food stamp income actually lowers nutrient intake ceteris paribus is a novel result for studies of the food stamp program but it would not be novel in the literature on nutrition in less developed countries pitt and rosenzweig 1985 behrman and deolalikar 1987 it is reasonable to believe that as income increases households employ relatively more money than time in household production this is silberberg s 1985 explanation for decreased efficiency in producing pure nutrients in other words as income increases people spend less time preparing meals and more money on foods which are easier to prepare if as is often the case foods which are more convenient to prepare are less nutritious than foods which require a lot of time to prepare then our result is not surprising

democracy and economic growth a meta analysis despite a sizeable theoretical and empirical literature no firm conclusions have been drawn regarding the impact of political democracy on economic growth this article challenges the consensus of an inconclusive relationship through a quantitative assessment of the democracy growth literature it applies meta regression analysis to the population of 483 estimates derived from 84 studies on democracy and growth using traditional meta analysis estimators the bootstrap and fixed and random effects meta regression models it derives several robust conclusions taking all the available published evidence together it concludes that democracy does not have a direct impact on economic growth however democracy has robust significant and positive indirect effects through higher human capital lower inflation lower political instability and higher levels of economic freedom democracies may also be associated with larger governments and less free international trade there also appear to be country and region specific democracy growth effects overall democracy s net effect on the economy does not seem to be detrimental

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

wife s employment food expenditures and apparent nutrient intake evidence from canada the increase in women working outside the home has had important economic effects one effect involves food expenditures both in terms of patterns of eating out and the types of foods prepared in the home with consequent effects on nutrient availability this study examines the effect of wife s employment on an extensive set of variables describing food behavior the variables include the share of food in total expenditure the share of food away from home fafh in the food budget price paid per calorie and the per capita availability of twelve nutrients the results are of potential interest for food policy for nutrition education and for programs which aim to affect the nutrient composition of food eaten outside the home restaurant food fast food school meals etc in ad

does law and order attenuate the benefits of democracy on economic growth recent studies have reported positive associations between democracy and economic growth they have also explored how associations could differ across regions or income levels however might the effects of democracy on growth also depend on factors such as institutions promoting law and order using a panel specification we employ a democracy law and order interactive term to examine if the effects of democracy on economic growth depend on these other institutions we find that positive effects of democracy diminish and might even turn negative in countries where other institutions such as those supporting law and order are strong

on the dynamics of ethnic fractionalization does fractionalization change over short periods of time if so are there any substantial implications for economic performance to answer such questions we construct a new panel data set with measures of ethnic linguistic and religious fractionalization for 26 former communist countries covering the period from 1989 to 2002 our fractionalization measures show that transition economies became more ethnically homogeneous over such a short period of time although the same did not happen for linguistic and religious diversity in line with the most recent literature there seems to be no effect of exogenous diversity on macroeconomic performance that is on per capita gdp growth however we find that dynamic endogenous ethnic diversity is negatively related to growth although this is still not the case for linguistic and religious diversity these findings are robust to different specifications polarization measures and instrument sets as well as to a composite index of ethnic linguistic religious fractionalization

child allowances and allocative decisions in romanian households in this paper it is tested whether increasing child allowances will affect the intra household allocation of consumption measured by child and adult goods holding total household resources constant the analysis is based on household survey data collected in romania where cash payments are made to families according to the number and age of children selectivity is controled for since there is the potential for self selection bias in terms of the level of child allowances received the findings suggest that holding total household resources constant child allowances increase demand for child goods and calories and reduce demand for adult goods

shared producer and consumer responsibility theory and practice abstract over the past decade an increasing number of authors have been examining the nexus of producer versus consumer responsibility often dealing with the question of how to assign responsibility for internationally traded greenhouse gas emissions recently a similar problem has appeared in drafting the standards for the ecological footprint while the method traditionally assumes a full life cycle perspective with full consumer responsibility a large number of producers businesses and industry sectors have started to calculate their own footprints see www isa org usyd edu au adding any producer s footprint to other producers footprints or to population footprints which all already cover the full upstream supply chain of their operating inputs leads to double counting the sum of footprints of producers and consumers is larger than the total national footprint the committee in charge of the footprint standardisation process was hence faced with the decades old non additivity problem posing the following dilemma for the accounting of footprints or any other production factor if one disallows double counting but wishes to be able to account for producers and consumers then one cannot impose the requirement of full life cycle coverage the supply chains of actors have to be curtailed somehow in order to avoid double counting this work demonstrates and discusses a non arbitrary method of consistently delineating these supply chains into mutually exclusive and collectively exhaustive portions of responsibility to be shared by all actors in an economy

the influence of household composition on household expenditure patterns theory and spanish evidence a concept of demographic separability is proposed that formalizes the notion that there are groups of goods adult goods that have little or no relationship to specific classes of household demographics the numbers or ages of children that there exist adult goods demographically separable from children is a necessary but not sufficient condition for the validity of rothbarth s method for measuring child costs we propose two different methods for testing demographic separability and present results from a 1981 survey of spain the econometric evidence is in fair agreement with the theoretical presuppositions

ethnic discrimination and the migration of skilled labor we develop a model of interdependency between emigration education investment and discrimination in the context of an ethnically divided developing economy assuming a rent extraction basis for discrimination we first endogenize ethnic discrimination in the benchmark case of an economy closed to migration and then explore how migration prospects affect ethnic inequality under the free migration assumption we find the intuitive result that migration prospects have a protective effect on the minority immigration restrictions set by receiving countries on the other hand have the paradoxical effect of creating migration flows that would otherwise have remained latent

are estimates of calorie income fxelasticities too high a recalibration of the plausible range abstract the wide range of calorie income elasticities in the literature results in large part from the particular calorie and income variables used for estimation elasticities across four estimation techniques and four calorie income variable pairs for a sample of philippine farm households ranged from 0 03 to 0 59 estimates associated with calorie availability are biased upwards first because random errors in measuring food purchases are transmitted by construction both to calorie availability and total expenditures and second because the residual difference between family calorie intake and household calorie availability will often increase with income the calorie intake total expenditure variable pair gives the preferred elasticity estimate in the 0 08 0 14 range

productivity health and inequality in the intrahousehold distribution of food in low income countries a model is formulated incorporating linkages among nutrition labor market productivity health heterogeneity and the intrahousehold distribution of food and work activities in a subsistence economy empirical results based on a sample of households from bangladesh indicate that despite considerable intrahousehold disparities in calorie consumption households are averse to inequality furthermore consistent with the model the results also indicate that both the higher level and greater variance in the calories consumed by men relative to women reflect in part the greater participation by men in activities in which productivity is sensitive to health status copyright 1990 by american economic association

nash bargained household decisions reply pierre andre chiappori s 1988 claim that the nash bargaining model is of weak empirical relevance and neither convenient nor really restrictive is incorrect nash bargained household behavior implies a rich set of empirical implications extending well beyond the pareto efficiency of intrafamily distributions by systematically accounting for the impact of opportunities outside the family on resource distribution within the family nash bargained demand theory considerably expands the scope of neoclassical demand theory such expansion can elucidate issues ranging from the impact of alimony and child support laws in developed societies to the intrafamily distribution of nutrition in less developed countries copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the effect of income on demand for food in poor countries are our food consumption databases giving us reliable estimates abstract cross section estimates of income elasticities for food staples in the aggregate based on quantity information from household food expenditure surveys are often in the 0 3 0 6 range it is shown that differences in per capita calorie intakes across income groups implied by these income elasticities are grossly inconsistent with observed differences in bodyweights moreover time series data frequently indicate that national per capita consumption of food staples in the aggregate remains constant even as per capita gross national product rises substantially cross section income elasticity estimates are biased upwards due to the failure of food expenditure surveys to undertake an accurate accounting of food transfers from high to low income groups biases which are not generated by survey techniques which record food intakes directly

ethnic diversity and economic development abstract this paper analyzes the role that different indices and dimensions of ethnicity play in the process of economic development firstly we discuss the advantages and disadvantages of alternative data sources for the construction of indices of religious and ethnic heterogeneity secondly we compare the index of fractionalization and the index of polarization we argue that an index of the family of discrete polarization measures is the adequate indicator to measure potential conflict we find that ethnic religious polarization has a large and negative effect on economic development through the reduction of investment and the increase of government consumption and the probability of a civil conflict

do husbands and wives pool their resources evidence from the united kingdom child benefit common preference models of family behavior imply income pooling a restriction on family demand functions such that only the sum of husband s income and wife s income affects the allocation of goods and time testing the pooling hypothesis is difficult because most family income sources are not exogenous to the allocations being analyzed in this paper we present an alternative test based on a natural experiment a policy change in the united kingdom that transferred a substantial child allowance to wives in the late 1970s using family expenditure survey data we find strong evidence that a shift toward greater expenditures on women s clothing and children s clothing relative to men s clothing coincided with this income redistribution

can democracy help growth and ethnic divisions this paper presents further empirical evidence suggestive of democracy s positive role in ameliorating the negative growth effects of ethnic diversity in nations however it is shown that endogeneity problems and a direct negative growth effect of democracy place inherent limitations on the strength of policy implications which may be drawn from the evidence

looking for boy girl discrimination in household expenditure data the ability to test for discrimination in the allocation of goods between boys and girls is hampered by a lack of data on intrahousehold distribution the analysis presented here allows inferences about intrahousehold allocation to be made from householdlevel expenditure data for a given level of income families with children will spend less on adult goods in order to purchase children s goods if household purchasing favors boys over girls smaller expenditures on adult goods would be made by families with boys as compared with those with girls a method for determining adult goods is described and the procedure for detecting gender bias is applied to data from c6te d lvoire and thailand the data show no evidence of discriminatio n between boys and girls in c6te d lvoire and a small and statistically insignificant bias in favor of boys in thailand how commodities are allocated among the members of a household has recently occasioned a good deal of interest assessments of poverty and income distribution based on household incomes or expenditures will be misleading if allocation within the household is unequal the position of women and girls has been of particular concern and there is a considerable amount of empirical evidence much of it from the indian subcontinent that documents discrimination against females see in particular bhagwati 1973 sen 1984 sen and sengupta 1983 miller 1981 bardhan 1982 and kynch and sen 1983 as well as survey papers by behrman 1987 and harriss 1987 much of the evidence is concerned with measurements of nutritional outcomes mortality and health status rather than with the direct allocation of goods by gender the difficulty in trying to determine the intrahousehold allocation of goods is that household budget surveys the obvious source of data record consumption not of individuals but of households and while attempts can be made to the author is a professor of public affairs and of economics and international affairs at princeton university and is a consultant to the population and human resources department of the world bank the author thanks dwayne benjamin who provided for excellent research assistance he is grateful to him and to members of the economic growth center at yale university for helpful comments this is a revised and shortened version of living standards measurement study working paper 39 the allocation of goods within the household adults children and gender june 1987 the results from thailand were not included in the working paper 1989 the international bank for reconstruction and development the world bank

the effect of price and income changes on food energy intake in sri lanka data is used to analyze the food acquisition behavior of households from a 1980 81 survey designed to be nationally sectorally and regionally representative of sri lanka the poor are shown to be much more responsive to price and income changes than other income groups the urban population generally exhibits lower income elasticities of demand for food commodities the poor appear to efficient substitutors thereby mitigating the effects of a price change on caloric intake the important exception is rice whose elasticity of calorie consumption with respect to price was about 4 times higher than for any other commodity the reluctance of households to substitute for rice even when faced with rising prices coupled with its large budget share show rice to be the most important consumption good higher rice prices are an important determinant of poverty for landless and urban workers moderating food prices preferably through technological change is a key ingredient to raising consumption among the poor simulations show that even if there are rapid and proportional increases in expenditures of all income groups this will not dramatically increase caloric intake among the poor however if the absolute value of the increase in real expenditures were distributed equally to all households there would be a marked increase in the of households consuming an adequate diet

dietary effects of the food stamp program based on data from the 1979 80 survey of food consumption in low income households this paper estimates the effects of changes in cash income and the food stamp benefit on household nutrient availability while controlling for two potential sources of selection bias the major finding of the empirical analysis is that the estimated dietary effects of changes in food stamp benefits are considerably larger than those resulting from changes in cash income with estimates of the ratios of the mpc for the food stamp benefit to the cash income mpc ranging from three to seven across nutrients no significant evidence of selection bias was found and the estimated dietary effects of food stamp benefits from the selection bias models are similar to those from the basic model estimated by ordinary least squares regression

joint determination of food consumption and production in rural sierra leone estimates of a household firm model abstract this paper investigates the determination of food consumption for rural households in sierra leone that produce the foods which they consume a household firm model is estimated with seven commodities including five foods non foods and labor as compared to three commodities in past studies such food disaggregation permits tracing of the effects of socioeconomic variables on household nutrient availability household specialization in production is such that censored data is a problem a tobit approach is used to correct for this for most crops the own price effects on consumption remain negative when a price change is allowed to shift the budget constraint by effecting the profits from home production elasticities of calorie availability with respect to toal expenditure are found to be sizeable varying little by expenditure group the price elasticities of calorie availability are generally positive however an important exception occurs for price of the staple food rice this exception has several important policy implications which are explored

parental investment in children s human capital in urban china the present study tests the extent of parental forgone consumption used instead to invest in children s human capital by use of intrahousehold resource allocation models using an unusual comprehensive data set for urban china there is more spending on boys aged 13 to 15 but more on girls aged 16 to 18 suggesting that standard human capital theories and traditional perceptions of gender bias do not completely explain educational expenditure decisions the evidence from urban china is consistent though with human capital models which consider parental intertemporal preferences also the findings suggest that the perceived bias in favour of sons exists weakly in contemporary urban china

will developing country nutrition improve with income a case study for rural south india aggregate estimates of food expenditure are consistent with such a possibility implying income expenditure elasticities close to one however the high degree of aggregation at which such estimates are made means that the considerable increase in price per nutrient as income increases is ignored and the nutrient elasticities are therefore overstated estimates for a rural south indian sample indicate that this bias is considerable and that the true nutrient elasticities with respect to income may be close to zero

on sustainability interpretations of the ecological footprint abstract this paper focuses on using the ecological footprint concept for sustainability assessment the ecological footprint is a popular indicator of human use of environmental resources and is commonly presented at the country level by comparing the consumption footprint with territorial biocapacity with a negative balance implying unsustainability this constrains a country s consumption by its biocapacity but allows its stock of resources to be depleted if they are not associated with domestic consumption this paper argues that this approach is legitimate but should not automatically constitute a default framework for interpretation two perspectives on entitlements to environmental resources are analyzed and based on them a novel approach to sustainability assessment is proposed the paper further discusses the links between national sustainability and the related issues of self sufficiency consumption and responsibility

investment credit and child labour it is generally assumed that credit has a positive effect on children s schooling among poor households this article shows that need not be the case when households obtain credit for investment purposes in fact investment loans may not have any effect on the likelihood of schooling for children who work in their family business our estimates confirm that this is the case credit used to finance investments has no effect on the odds of schooling for employed children this may be because investment loans increase children s labour productivity which in turn increases the opportunity cost of schooling the results of this study suggest that improving access to credit may not by itself constitute a solution to the problem of child labour in developing countries

is there an intrahousehold flypaper effect evidence from a school feeding programme are public transfers targeted toward children neutralised by the household as the theory of altruism implies or is there an intrahousehold flypaper effect whereby such transfers stick to the child this paper studies the impact of a school feeding programme on child caloric intake in the philippines using a quasi experimental methodology the empirical results confirm an intrahousehold flypaper effect indeed they indicate virtually no intrahousehold reallocation of calories in response to the feeding programme in poorer households however children s gains from the programme appear to be taxed more heavily

intra household resource allocation an inferential approach if household income is pooled and then allocated to maximize welfare then income under the control of mothers and fathers should have the same impact on demand with survey data on family health and nutrition in brazil the equality of parental income effects is rejected unearned income in the hands of a mother has a bigger effect on her family s health than income under the control of a father for child survival probabilities the effect is almost twenty times bigger the common preference or neoclassical model of the household is rejected if unearned income is measured with error and income is pooled then the ratio of maternal to paternal income effects should be the same equality of the ratios cannot be rejected there is also evidence for gender preference mothers prefer to devote resources to improving the nutritional status of their daughters fathers to sons

testing the neoclassical model of family labor supply and fertility the mcelroy horney nash bargaining model of family demand behavior relaxes the restriction that nonearned income of husband and wife has the identical effect on family labor supply and commodity demands this restriction of the neoclassical model offamily behavior is tested for the determination of husband and wife labor supply andfertility based on the 1981 socioeconomic survey of thailand the neoclassical restriction is rejected for female labor supply andfertility another unexplored limitation offamily demand studies due to the sample self selection of intact marriages is empirically treated through alternative estimation strategies in this case a more sharply focused theory of marital behavior is needed to identify family demand models

transfer payments mothers income and child health in ecuador abstract we evaluate the impact of the bono solidario a transfer payment scheme in ecuador on children s nutritional status in addition to testing for pure income effects because the programme transferred money to mothers of young children we test whether mother s income has a stronger effect on children s heights and weights than ordinary household income we draw two main conclusions that the bono solidario transfer payment scheme has had a statistically significant but quite modest impact on children s nutritional status and that this impact is no different than any other income effect on height and weight in particular the fact that the bono is transferred to mothers has not made it more efficacious at reducing malnutrition than other household income

the demand for food and calories we investigate nutrition and expenditure in rural maharashtra in india we estimate that the elasticity of calorie consumption with respect to total expenditure is 0 3 0 5 a range that is in accord with conventional wisdom the elasticity declines only slowly with levels of living and is far from the value of zero suggested by a recent revisionist literature in these indian data the calories necessary for a day s activity cost less than 5 percent of the daily wage which makes it implausible that income is constrained by nutrition rather than the other way around

separate spheres bargaining and the marriage market this paper introduces the separate spheres bargaining model a new model of distribution within marriage it differs from divorce threat bargaining models e g manser brown mcelroy horney in that the threat point is not divorce but a noncooperative equilibrium within marriage this noncooperative equilibrium reflects traditional gender roles the predictions of our model thus differ from those of divorce threat bargaining models in the separate spheres model cash transfer payments to the mother and payments to the father can but need not imply different equilibrium distributions in existing marriages in the long run the distributional effects of transfer policies may be substantially altered by changes in the marriage market equilibrium

income based environmental responsibility abstract a strong mitigation effort is underway to reduce the levels of anthropogenic greenhouse gas emissions an allocation of the mitigation effort among multiple agents requires understanding which agent is responsible for what emissions according to a defined measure of carbon responsibility the metric adopted by current international climate policy is production based or territorial responsibility however other types of responsibility have been discussed in the literature namely consumption based or upstream responsibility and downstream responsibility in this paper we study the latter which is little explored in the literature we clarify the term through a novel nomenclature income based responsibility and present a case study with the quantification of income based responsibility for 112 world regions and the comparison of the results with production and consumption based responsibilities

income and outcomes a structural model of intrahousehold allocation there is evidence from several sources that one cannot treat many person households as a single decision maker if this is the case then factors such as the relative incomes of the household members may affect the final allocation decisions made by the household we develop a method of identifying how incomes affect outcomes given conventional family expenditure data the basic assumption we make is that household decision processes lead to efficient outcomes we apply our method to a sample of canadian couples with no children we find that the final allocations of expenditures on each partner depend significantly on their relative incomes and ages and on the level of lifetime wealth

identification and panel data models with endogenous regressors this paper provides sufficient conditions for the identification of both static and dynamic models containing endogenous regressors from panel data by utilizing the restrictions across time periods on the parameters it is shown that identification is achieved under quite weak conditions even in the presence of a general pattern of correlation between the errors and the time varying variables efficient estimation procedures for the models considered and some specification tests are outlined finally static formulations relating individuals intakes of nutrients in the previous 24 hours to household incomes are estimated using icrisat panel data from rural india

the impact of food stamps on food expenditures rejection of the traditional model for food stamp recipients whose normal food purchases exceed their coupon allotment the traditional economic model predicts that the impact of food stamps on food spending will be the same as for an equal cash transfer the tobit analysis in this study indicates that for these recipients food stamps have a substantially greater impact on at home food expenditures than an equal amount of cash income these results reject the traditional model several possible explanations of this behavior are discussed

more evidence on nutrition demand income seems overrated and women s schooling underemphasized abstract malnutrition is widespread in the developing world controversy continues concerning the roles of income household size and women s schooling on nutrient demand empirical estimates for nicaragua suggest that income elasticities are small and inversely associated with income levels there are some economies of scale in household size the elasticity for women s schooling is higher than those for income or household size and women s backgrounds are important the results cast doubt on the strong emphasis the world bank and others have placed on income and suggest that schooling may be working through tastes not only through productivity
