where has all the bias gone detecting gender bias in the intrahousehold allocation of educational expenditure abstract the reliability of the household consumption based engel curve methodology in detecting gender bias has been called into question because it has generally failed to confirm bias even where it exists this article seeks to find explanations for this failure by exploiting a data set that has educational expenditure information at the individual level and also by aggregation at the household level i find that in the basic education age groups the discriminatory mechanism in education is via differential enrollment rates for boys and girls education expenditure conditional on enrollment is equal for boys and girls the engel curve method fails for two reasons first it models a single equation for the two stage process second even when we make individual and household level expenditure equations as similar as possible the household level equation still fails to pick up gender bias in about one third of the cases where the individual level equation shows significant bias this article

does survey recall error explain the deaton paxson puzzle using recall and diary food expenditure data from canada we compare estimates of the household size elasticity of per capita food expenditure in contrast to gibson 2002 we find negative elasticities in both recall and diary data this in turn means we find evidence of the deaton paxson puzzle in both diary and recall data recall error cannot be the sole explanation of the puzzle

multiple experiments for the causal link between the quantity and quality of children this article presents evidence on the child quantity child quality trade off using quasi experimental variation due to twin births and preferences for a mixed sibling sex composition as well as ethnic differences in the effects of these variables our sample includes groups with very high fertility an innovation in our econometric approach is the juxtaposition of results from multiple instrumental variables strategies capturing the effects of fertility over different ranges for different sorts of people to increase precision we develop an estimator that combines different instrument sets across partially overlapping parity specific subsamples our results are remarkably consistent in showing no evidence of a quantity quality trade off

endogenous lifetime and economic growth abstract endogenous mortality is introduced in a two period overlapping generations model probability of surviving from the first period to the next depends upon health capital that is augmented through public investment high mortality societies do not grow fast since shorter lifespans discourage savings development traps are possible productivity differences across nations result in persistent differences in capital output ratios and relatively larger gaps in income and mortality high mortality also reduces returns on education where risks are undiversifiable when human capital drives economic growth countries differing in health capital do not converge to similar living standards threshold effects may also result

how do households cope with aggregate shocks evidence from the mexican peso crisis abstract household surveys are used to examine the micro impact of a large aggregate shock the 1995 mexican peso crisis this paper examines how the impact of the crisis differed across households and the adjustment mechanisms used by households to cope with this shock the coping strategies examined include changes in household structure fertility household labor supply child schooling and interhousehold transfers many of the mechanisms households use to adapt to idiosyncratic shocks are found not to work with an aggregate shock

learning by doing and the introduction of new goods a dynamic general equilibrium model is developed in which goods are valued according to the characteristics they contain the set of goods produced in any period is endogenously determined and learning by doing is the force behind sustained growth it is shown that the set of produced goods changes in a systematic way over time with goods of higher quality entering each period and those of lower quality dropping out the model is then used to study the effect of introducing a traditional sector in which there is no learning

parental benefits from intergenerational coresidence empirical evidence from rural pakistan this paper explains the negative correlation between the days of work reported by fathers in rural pakistani households and the incomes earned by their coresident adult sons thereby contributing to research on the benefits from intergenerational coresidence i find that the decline in fathers days of work that accompanies increases in sons incomes primarily results because such income is used to finance expenditures on household public goods such as consumer durables and ceremonies empirical tests reject most alternative explanations of the benefits of coresidence including the belief that sons contribute to fathers wealth

estimating consumption deprivation in india using survey data a state level rural urban analysis before and during reform period this paper assesses deprivation in india employing a measure proposed by sitaramam and using consumption data at the household level as cereals constitute a staple food and form a major portion of expenditure on food the deprivation measure considered here is deprivation in cereal consumption the total expenditure at which the engel curve for cereals turns from concave to convex is taken as the cut off to determine the deprived households it is shown that cereal deprivation at the all india level exhibits a declining trend over the period 1987 88 and 1999 2000 in the rural sector while there is little change in the urban sector further this decline in cereal deprivation seems to have been slowing down during the reform period the estimates of deprivation are poorly correlated with the hci and pgi at state level both in rural and urban sectors they however have better temporal correlations with those poverty measures we offer some explanation for these observed differences in alternate deprivation indices the trends in cereal deprivation are accompanied in some cases by a decline in real terms in maximum cereal consumption of each group of consumers whether this is an improvement or otherwise of the living standards of the poor must await further analysis of per capita food consumption in general with an analysis of prices and quantities of various food items it is hoped that this kind of study on deprivation of essential commodities may increase our understanding of poverty and even suggest direct intervention strategies

risk taking global diversification and growth this paper develops a continuous time stochastic model in which international risk sharing can yield substantial welfare gains through its effect on expected consumption growth the mechanism linking global diversification to growth is an attendant world portfolio shift from safe low yield capital to riskier high yield capital the presence of these two types of capital captures the idea that growth depends on the availability of an ever increasing array of specialized hence inherently risky production inputs calibration exercises using consumption and stock market data imply that most countries reap large steady state welfare gains from global financial integration copyright 1994 by american economic association

estimation of censored demand equations from large cross section data the article develops an alternative econometric methodology to estimate a system of censored demand equations using a large cross section data from colombian urban households the approach preserves the behavioralinformation expressed by zero expenditures and conforms with the requirements imposed by consumer theory in a way consistent with the random utility hypothesis we motivate the choice of the tobit modelas a statistical representation of consumer behavior and introduce the methodology by specifying the aids model modified according to both a translating and scaling demographic transformation we propose to estimate each demand equation in unrestricted form using the jackknife technique we then recover the demand parameters imposing the cross equations restrictions by using minimum distance estimation the empirical results of the censored demand system for specific households of policy relevance are reported copyright 2000 oxford university press

informal insurance arrangements with limited commitment theory and evidence from village economies recent work on consumption allocations in village economies finds that idiosyncratic variation in consumption is systematically related to idiosyncratic variation in income thus rejecting the hypothesis of full risk pooling we attempt to explain these observations by adding limited commitment as an impediment to risk pooling we provide a general dynamic model and completely characterise efficient informal insurance arrangements constrained by limited commitment and test the model using data from three indian villages we find that the model can fully explain the dynamic response of consumption to income but that it fails to explain the distribution of consumption across households

understanding poverty among the elderly in india implications for social pension policy abstract since 1995 cash transfers to the poor elderly or social pensions have been one of the most important anti poverty programmes in india on the assumption that elderly poverty rates are higher than the general population the minimum eligibility condition is set for 60 in most states our analysis using 52nd and 60th round household level national sample survey data however suggests that households with targeted elderly members 60 do not necessarily have higher poverty rates than non elderly households further analysis suggests that there is an expenditure mortality link so that the poor tend to die younger and are therefore under represented among those aged 60 in most states

determinants of income mobility and household poverty dynamics in south africa this article analyses household income mobility among africans in south africa s most populous province kwazulu natal between 1993 and 1998 compared to industrialised and most developing countries mobility has been quite high as might have been expected after the transition in south africa this finding is robust when measurement error is controlled for when disaggregating the sources of mobility it is found that demographic changes and employment changes account for most of the mobility observed which is related to rapidly shifting household boundaries and a very volatile labour market in an environment of high unemployment using a multivariate analysis it can be seen that transitory incomes play a large role four types of poverty traps are found associated with large initial household size poor initial education poor initial asset endowment and poor initial employment access that dominate the otherwise observed regression towards the mean

the precious bane abstract are natural resources harmful to growth we address this question using a two sector endogenous growth model in which human capital is the engine of growth by increasing the rewards to unskilled labor natural resources make schooling more expensive as long as the intertemporal elasticity of consumption substitution is not too high this slows down human capital accumulation and growth the presence of production spillovers from human capital however implies that a planner could react to a resource boom by increasing human capital accumulation even though the decentralized solution yields the exact opposite the paper also shows that as the production complementarity between natural resources and unskilled labor declines the growth effects of natural resources become increasingly sensitive to whether or not there is free trade in goods the empirical evidence lends support to the main channel natural resources to human capital to growth that is suggested in the paper

poverty and household size the widely held view that larger families tend to be poorer in developing countries has influenced research and policy the scope for size economies in consumption cautions against this view we find that the correlation between poverty and size vanishes in pakistan when the size elasticity of the cost of living is about 0 6 this turns out to be the elasticity implied by a modified version of the food share method of setting scales by contrast some measures of child nutritional status indicate an elasticity of unity consideration of the weight attached to child versus adult welfare may help resolve the non robustness of demographic profiles of poverty excerpt

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

quinoa quandary cultural tastes and nutrition in peru abstract using a model of household food demand that incorporates regional preferences tastes for culturally appropriate food i investigate whether tastes for quinoa in the puno region of peru reduced household nutrition intakes when quinoa prices dramatically increased between 2004 and 2012 adapting a model from atkin 2013 and utilizing data from a national peruvian household survey enaho i am able to deconstruct regional changes in household nutrition over time into several general equilibrium effects in particular i isolate the effect of regional tastes for quinoa on nutrition outcomes this effect is identified by an exogenous spike in quinoa prices driven by international demand for quinoa while i find evidence that regional tastes for quinoa do exist in the puno region these tastes do not have a statistically significant impact on nutrition outcomes my results lend support to the conjecture that tastes for culturally appropriate food do not meaningfully affect household nutrition if the food in question is a sufficiently small component of a household s overall diet

the distributional impacts of indonesia s financial crisis on household welfare analyzing the distributional impacts of economic crises is an ever more pressing need if policymakers are to intervene to help those most adversely affected they need to identify those who have been hurt most and estimate the magnitude of the harm they have suffered they must also respond in a timely manner this article develops a simple methodology for measuring these effects and applies it to analyze the impact of the indonesian economic crisis on household welfare using only pre crisis household information it estimates the compensating variation for indonesian households following the 1997 asian currency crisis and then explores the results with flexible nonparametric methods it finds that virtually every household was severely affected although the urban poor fared the worst the ability of poor rural households to produce food mitigated the worst consequences of the high inflation the distributional consequences are the same whether or not households are permitted to substitute toward relat

labour supply and wages among nuclear and extended households the surinamese experiment this article explores labour market behaviour of members of extended and nuclear households in suriname previous analyses have found that co operative childcare opportunities within the extended household increase female labour force participation such coordination implies correlated participation decisions which invalidates standard assumptions made in estimating participation with probits and wages with regressions we employ a gmm estimation which allows correlation among household members we find that extended and nuclear household members are not significantly different in participation propensities but do differ significantly in wages we argue that greater home production opportunities in extended households dilute labour market effort and hours reducing earnings

are women overrepresented among the poor an analysis of poverty in 10 developing countries abstract this paper presents new evidence on the proportion of women in poverty in 10 developing countries it compares poverty measures for males and females and for male and female headed households and investigates the sensitivity of these measures to the use of per capita and per adult equivalent units and different definitions of the poverty line while poverty measures are higher for female headed households and for females the differences are significant in only a fifth to a third of the datasets the contribution of female headed households to aggregate poverty is less than that of females due to the low population share of the former stochastic dominance analysis reveals that differences between male and female headed households and between males and females are often insignificant except for ghana and bangladesh where females are consistently worse off these results suggest that cultural and institutional factors may be responsible for higher poverty among women in these countries our results point to the need to analyze determinants of household income and consumption using multivariate methods and to give greater attention to the processes underlying female headship

trade tastes and nutrition in india this paper introduces habit formation into an otherwise standard model of international trade household tastes evolve over time to favor foods consumed as a child the opening of trade causes preferred goods to rise in price as these were relatively inexpensive in autarky neglecting the correlation between tastes and agro climatic endowments overstates the short run nutritional gains from agricultural trade liberalization and masks potential caloric losses for laborers i examine the predictions of this model of trade with habit formation using household survey data from india both by looking across indian regions and by examining the consumption patterns of inter state migrants

estimating the value of an in kind transfer the case of food stamps the value of one in kind transfer food stamps is estimated by evaluating the experience of an actual conversion from stamps to cash in puerto rico in 1982 the evidence indicates that the cashout of the stamps had no detectable influence on food expenditures the explanation partly lies in the distribution of expenditures for the stamps were inframarginal for most recipients however some evidence indicates that trafficking in stamps was widespread as well including indirect evidence from estimation of the piecewise linear constraint model copyright 1989 by the econometric society

a bayesian sampling approach to measuring the price responsiveness of gasoline demand using a constrained partially linear model partial linear models provide an intuitively appealing way to examine gasoline demand because one can examine how response to price varies according to the price level and people s income however despite their intuitive appeal partial linear models have tended to produce implausible and or erratic price effects blundell et al 2012 propose a solution to this problem that involves using slutsky shape restrictions to improve the precision of the nonparametric estimate of the demand function they propose estimating a constrained partially linear model through three steps where the weights are optimized by minimizing an objective function under the slutsky constraint bandwidths are selected through least squares cross validation and linear coefficients are estimated using profile least squares a limitation of their three step estimation method is that bandwidths are selected based on pre estimated parameters we improve on the blundell et al 2012 solution in that we derive a posterior and develop a posterior simulation algorithm to simultaneously estimate the linear coefficients bandwidths in the kernel estimator and the weights imposed by the slutsky condition with our proposed sampling algorithm we estimate a constrained partially linear model of household gasoline demand employing household survey data for the united states for 1991 and 2001 and for canada for 2006 2009 and find plausible price effects

economies of scale household size and the demand for food household scale economies are plausibly attributed to shared household public goods that make larger households better off at the same level of per capita resources larger households should therefore have higher per capita consumption of private goods such as food provided that they do not substitute too much toward the effectively cheaper public goods the evidence shows exactly the opposite data from rich and poor countries indicate that at constant per capita total expenditure the per capita demand for food decreases with household size and that it does so most in the poorest countries where substitution should be the least

the power of the vegetable patch how home grown food helps large rural households achieve economies of scale escape poverty this paper explores how the household s capacity to grow food impacts their ability to achieve economies of scale in food consumption and how this impacts the geographic distribution of poverty across rural and urban areas an accurate understanding of consumption economies of scale is vital for comparing poverty levels across households of varying size using sri lankan data on home grown food consumption we empirically confirm that such economies of scale exist and that large households tend to consume relatively more home grown food than smaller households the magnitude of these scale economies are found to be larger than those in market purchased food but smaller than those found in housing expenditure consuming more home grown food is also found to be positively correlated with per capita calories consumed taking these effects into account in poverty estimates leads to a 15 per cent decline in the number of household who fall below the poverty line in rural regions

a path dependent approach to security valuation with application to interest rate contingent claims abstract the last two decades have witnessed a tremendous growth in the volume of assets and liabilities whose cash flows depend in a variety of ways on the path of interest rates some of these including floating rate notes and swap agreements contractually base cash flows on current and past interest rates and contain caps floors and other more complex features others including mortgages many corporate bonds and time deposits are fixed rate instruments that contain embedded options such as those to prepay call or withdrawal the irregular exercise of these options causes cash flows to vary as time proceeds and interest rates rise or fall this paper develops a state contingent claims technique for valuing such securities it is derived from the option based model of breeden and litzenberger 1978 using the transition matrix approach of banz and miller 1978 particular attention is paid to valuing so called path dependent securities whose contemporaneous cash flows depend on the historical path of interest rates as well as their current level a detailed example is provided in which an adjustable rate mortgage is valued under a variety of economic and security specific assumptions

the environmental impact of sharing household and urban economies in co2 emissions abstract studies find that per capita carbon dioxide co 2 emissions decrease with household size and urban density the demographic trends of declining household size and dense urbanization therefore produce countervailing effects with respect to emissions we posit that both household and urban economies are driven by proximity and realized through sharing carbon intensive goods with detailed data from the united states consumer expenditure survey we construct a dataset of co 2 emissions at the household level and leverage a unique measure of residential density to estimate household and urban economies our estimates show that dense urban areas have per capita emissions roughly 20 lower than rural areas and that adding an additional member to a household reduces per capita emissions by about 6 we also find that household economies are about twice as large in rural areas as in dense urban areas and develop an explanation for this phenomenon in theory the carbon benefits of dense urbanization have the potential to offset the effects of declining household size however using historical us census data and extrapolating from our estimates we find that lost household economies have outpaced increased urban economies over the past fifty years

international risk sharing and economic growth international risk sharing which diversifies away income risk will reduce saving with constant relative risk aversion if growth arises from the external effects of human capital accumulation then reducing saving will reduce growth welfare also may fall with risk sharing because endogenous growth with external effects of capital accumulation typically implies a competitive equilibrium growth rate already less than the optimal growth rate we demonstrate these results in a standard representative agent economy diversifying away rate of return risk also will reduce saving and growth rates if relative risk aversion exceeds one but this diversification always increases welfare this paper studies the effects of international risk sharing portfolio diversification in a world economy in which growth rates of income are endogenous growth is based upon the spillover effects of human capital accumulation as in lucas 1988 and romer 1986 there are positive economy wide spillovers of human capital intensity on individual labour productivity in section 2 we construct a multi country growth model with an infinitely lived representative agent in each country each country faces income risk but there is no aggregate uncertainty at the world level we focus on two market structures in the first structure there are no markets which allow for international diversification of country specific income risk in the second structure there are complete international markets for risksharing with no aggregate world uncertainty this completeness allows full diversification of country specific risk the paper has two central results first growth rates in all countries are lower in the equilibrium with full diversification second in this same structure welfare of each country may be lower than in an equilibrium without risk sharing the reasoning is as follows with external effects of capital accumulation the compet

preference heterogeneity power and intrahousehold decision making in rural malaysia abstract this paper examines conjugal household responsibilities roles preference heterogeneity and intrahousehold power relations in rural malay families its three major contributions are to provide an effective initial indicator of separate spheres within the family develop and implement a method for measuring the extent of conjugal preference heterogeneity and illustrate the value of combining this direct measure of preference heterogeneity with a measure of power in estimating household expenditure patterns for three major items food schooling and housing improvement these three measurement innovations applied to the rural malaysia context demonstrate the potential for more direct efforts to model and measure intrahousehold decisions

child labor urban proximity and household composition using detailed survey data from nepal this paper examines the determinants of child labor with a special emphasis on urban proximity we find that children residing in or near urban centers attend school more and work less in total but are more likely to be involved in wage work or in a small business the larger the urban center the stronger the effect is urban proximity is found to reduce the workload of children and improve school attendance up to 3 h of travel time from the city in areas of commercialized agriculture located 3 to 7 h from the city children do more farm work urban proximity effects are accounted for by a combination of local labor supply and demand conditions most notably the local importance of agriculture the education level of the parents and the local wage rate child servants which represent a small proportion of all children work much harder than other children and appear particularly at risk

the poor get poorer tracking relative poverty in india using a durables based mixture model abstract i propose the use of a durables based mixture model to identify the consumption class structure of a population the mixture model decomposes the marginal distribution of durables ownership across all households into three conditional distributions one each for lower middle and upper classes along with their weights in the population distribution endogenously determining class membership this approach provides a potentially deeper understanding of the dynamics of classes in particular the lower class than can be obtained using poverty lines or pca alone it avoids many well known problems with expenditure data ameliorates the impact of changing survey designs and enables an analysis of the behavior and membership of classes over time i use the mixture approach to show that the urban lower class in india became smaller but poorer during the 1990s

testing the barten model of economies of scale in household consumption toward resolving a paradox of deaton and paxson households enhance the welfare of constituents by sharing shelter and appliances and economizing in services such as maintenance child care and food preparation resources so conserved can be applied to more personal goods such as food clothing or beauty care economizing by households is an important factor to consider when measuring poverty and inequality in 1895 ernst engel observed that the share of food consumption in total consumption can be used to measure economic welfare across households of different sizes and incomes larger or richer households spend a smaller share of their total expenditure on food although more elaborate methods have been developed see e g a survey by browning 1992 the use of food share or the budget share of other bundles of necessities as a proxy for welfare remains a viable method for measuring poverty and studying equivalence scales see e g deaton and muellbauer 1986 lanjouw and ravallion 1995 engel s method is popular for its simplicity it has only one demand equation to be estimated with the food share of total expenditure as a dependent variable a single cross sectional survey usually provides sufficient data for the analysis and no information on prices is required

economies of scale and gender discrimination in transition the case of the republic of tajikistan this article tests for economies of scale and for evidence of discrimination based on gender lines in intra household consumption allocations using data from the living standards survey in the republic of tajikistan tlss overall results support the existence of household economies of scale in tajikistan however empirical evidence supporting boy girl discrimination is limited despite anecdotal evidence otherwise

the second engel law is it a paradox abstract the second engel law says that the engel curve for food moves out as family size increases thus showing a decrease in welfare what is puzzling though is that this regularity does not hold for equivalent income functions expressed in per capita terms deaton and paxon 1998 economies of scale household size and the demand for food journal of political economy 106 5 897 930 show that holding per capita total household expenditure constant per capita expenditure on food falls with the number of heads deaton and paxson s empirical evidence from developed and less developed countries seems to invalidate the claim of the second engel s law the main objective of this paper is to understand such paradoxical relationship between food consumption and household size our nonparametric empirical evidence drawn from the colombian 1985 urban survey shows that the food share is negatively related to total household per capita expenditure in line with deaton and paxson s claim but equivalent incomes shift to the right as theory predicts the regularity of our nonparametric results is an indication of a problem in the parametric specification of the engel curve modified by family size in fact using also the surveys of italy nepal djibouti and bangladesh we show that a theoretically plausible modified engel curve is coherent with the claim of the second engel law and explains deaton and paxson s paradox

economies of scale in the household puzzles and patterns from the american past i introduction in one example of economies of scale households with multiple members are able to achieve the same standard of living at lower per capita expenditures on public goods than smaller households for example if two adults unite to form one household the couple will be better off as they can share public goods such as housing lowering per capita expenditure on them the couple can funnel these savings into increased consumption of public goods more spacious housing than either could afford separately making each member better off than they were when they lived by themselves the basic idea has strong intuitive appeal living standards for households of different sizes could be equated with lower per capita expenditures for larger households who are able to economize on public goods household economies of scale are therefore fundamental to the measurement of living standards measuring the distribution of income the costs of children the extent of poverty and poverty thresholds necessitates an accounting for these economies of scale one difficulty with household economies of scale is that it can be difficult to estimate the size of the scale economy and household economies of scale are not as well defined as scale economies in production while economies of scale are a function of the size of the household the demand for goods and services generally derives from both household size and composition when researchers turned their attention to economies of scale in the household they overcame the problem of detection and measurement by concentrating on adult only households as in nelson 1988 measuring economies of scale for households where all members are the same type have identical tastes and are treated equally will not aid in the measurement of poverty the distribution of income and the costs of children where compositional heterogeneity matters a second difficulty lies in the income and substitution effects that scale economies have on private goods while both the income and substitution effects imply increased consumption of public goods the income and substitution effects work in opposite directions for private goods and it is not possible to know which effect will dominate unless we know more about the private good private goods that have low own and cross price elasticities and sizable income elasticities are goods whose consumption is likely to increase with household size the increased consumption of those private goods could be taken as a measure of household economies of scale where larger households are better off in terms of private consumption due to scale economies in public consumption using this insight deaton and paxson 1998 suggested that food would be a good choice for a private good where the income effect will dominate because food has few substitutes and they argue that substitution away from food will be less likely for households close to subsistence this implies that food expenditures should increase with household size the savings realized on public goods would be funneled to food a necessity that has few substitutes rather than increasing with household size deaton and paxson found that food expenditure per capita decreases with household size after considering and dismissing a number of possible explanations they conclude that their empirical results are a puzzle a literature analyzing this food puzzle has developed deaton and paxson 2003 gan and vernon 2003 gardes and starzec 2000 gibson 2002 gibson and kim 2007 horowitz 2002 perali 2001 vernon 2005 but research on household scale economies has yet to look at how or if scale economies change over time just as knowledge about scale economies at a point in time allows us to estimate the extent of poverty and inequality knowledge about changes in scale economies are useful for analyzing changes in living standards over time even more knowledge about changes in scale economies is important since average household size has changed over time

natural resource dependence human capital accumulation and economic growth a combined explanation for the resource curse and the resource blessing abstract in existing studies no consensus has been reached on the relationship between natural resource dependence and human capital accumulation to narrow the divergence this paper carries out a normative research to explain the co existence of the phenomena of the resource curse and the resource blessing based on an organic combination of conceptual and mathematical models it first establishes a conceptual model to analyse the potential effects of the government s policy preference and natural resource development activities on human capital accumulation and economic growth furthermore it develops an endogenous growth model to normatively illuminate the effects in the conceptual model and to explore the condition for the occurrence of the resource curse the conceptual model analysis indicates that the rate of return on education investment and government behaviours play the crucial role in promoting the formation of the economic virtuous circle at the micro level and macro level respectively while resource development activities exert dual impacts on the circle the main mechanisms in the conceptual model can be validated in the mathematical model the rise in the subjective discount rate the elasticity of intertemporal substitution and resource goods price are adverse to the economic virtuous circle while high quality education and the institutional environment giving priority to manufacturing can become the necessary condition and sufficient condition for forming the circle respectively the allocation efficiency of production factors plays a decisive role in whether the blessing occurs whereas sufficient human capital is an essential guarantee for evading the curse

world food demand long term projections of global food demand are heavily dependent on which functional form of the food demand equation is used given that real incomes can change substantially over the long term key elements are the dependence of the income elasticity on income which ensures that the food budget share always lies within the 0 1 range and the role of income inequality this article analyzes these issues proposes a new functional form that deals with them and presents estimates of income and price elasticities for food in 138 countries copyright 2012 oxford university press

an intertemporal analysis of expenditure elasticities under three expenditure specifications for sri lanka household income has been identified as one of the major determinants of demand for household goods in addition other household characteristics such as household size and composition are also fo

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

cpi bias and real living standards in russia during the transition abstract the economies of the former soviet bloc experienced large declines in output during the decade of transition which began with the collapse of the soviet union in 1991 yet there are many reasons to believe that measured output and official deflators provide a poor proxy for the change in real living standards in transition economies this paper uses the engel curve methodology developed by hamilton hamilton b 2001 using engel s law to estimate cpi bias american economic review 91 3 619 630 to examine changes in real living standards in russia during the transition period and to provide an estimate of how much the official russian cpi has overstated consumer inflation we also examine changes in consumer durables home production and subjective well being to further evaluate changes in living standards our findings indicate that cpi bias has caused a substantial understatement of the growth performance of the russian economy during the transition even just allowing household final consumption to be deflated with bias we find that the level of real per capita gdp in 2001 may be understated by up to 30 compared with using a bias corrected deflator our analysis of consumer durables home production and subjective well being supports the conclusion that the decline in living standards has been substantially less than what is inferred by looking at official statistics on real output

income variability evolving diets and elasticity estimation of demand for processed foods in nigeria we present evidence on evolving dietary patterns in nigeria using six rounds of household consumption data from the nigerian general household survey panel between 2011 and 2016 first following conventional definitions in the literature we show that nigeria has not shown any aggregate increase in consumption of highly processed foods over this period contrary to patterns observed elsewhere in the region in fact consumption of highly processed foods at home has declined while food consumed away from home often assumed to be highly processed has risen substantially we then show that estimates of food expenditure elasticities of different food types are highly sensitive to different estimation approaches and raise concerns about some frequently used methods in the literature in the absence of credible exogenous variation we argue for the importance of panel methods and household fixed effects to control for time invariant factors likely to confound cross sectional estimates finally we examine semiparametric engel curves for different food groups and find that apparent curvature in the relationships between food budget shares and overall food expenditure levels in the raw data become nearly linear when removing variation explained by time invariant household factors

the effect of food stamp cashout on food expenditures an assessment of the findings from four demonstrations using findings from four demonstrations we examine estimates of the effect on household food expenditures of converting food stamps into a cash transfer we provide arguments for why the estimate produced by one of the demonstrations should be regarded as an outlier the disparity in the difference in means estimates from the remaining three demonstrations is reduced when each is normalized by dividing by the average value of benefits in the respective demonstration site the normalized estimates imply a reduction in food expenditures of between 18 and 28 cents for each dollar of food stamps cashed out at the aggregate level these estimates imply that nationwide cashout would result in a reduction in household food spending of between 4 2 and 6 5 billion dollars whereas the associated reduction in the cost of administering the food stamp program would be about 0 3 billion dollars

push or pull the relationship between development trade and primary resource endowment abstract we develop a model to capture the interaction between transaction efficiency and primary resource endowment for specialization and development this interaction leads to four broad patterns of development countries with low primary resource endowment can be pushed into development so long as their institutions exhibit sufficient transaction efficiency otherwise development may fail to occur similarly a country may fail to develop because it is cursed by abundant natural resources if however that country has sufficiently high transaction efficiency it can overcome the curse and develop but the threshold level of transaction efficiency for development rises as natural resources become more abundant in this sense the institutional hurdle for development increases as natural resources become more abundant we consider the welfare effects of different development paths and also consider how technological development may aid or hinder development

household level consumption in urban ethiopia the effects of a large food price shock summary we use survey data to investigate how urban households in ethiopia coped with the food price shock in 2008 qualitative data indicate that the high food price inflation was by far the most adverse economic shock between 2004 and 2008 and that a significant proportion of households had to adjust food consumption in response regression results indicate that households with low asset levels and casual workers were particularly adversely affected by high food prices we interpret the results as pointing to the importance of growth in the formal sector so as to generate more well paid and stable jobs
