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

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

how reliable are household expenditures as a proxy for permanent income implications for the income nutrition relationship using short run expenditures from household surveys as a proxy may create attenuated estimates of the impact of permanent income on economic outcomes we use repeated observations to calculate reliability ratios and estimate errors in variables regressions of the impact of income on nutrition we find significant responses to income in contrast to previous influential studies

nonparametric and parametric analysis of calorie consumption in tanzania abstract the empirical literature on the demand for calories in developing countries suggests mixed results regarding the role of income and other socioeconomic characteristics on calorie demand this study employs both nonparametric and parametric methods to examine the impact of household expenditure and other socioeconomic variables on household demand for calories in tanzania using recent survey data the parametric methods include estimation strategies that ensure consistent estimates in the presence of behavioral endogeneity and measurement error under each estimation strategy we employ we find a strongly significant and positive relationship between household expenditure and calorie demand lending support to conventional wisdom that income growth can alleviate inadequate calorie intake the results also show a negative and significant relationship between food prices and calorie demand suggesting that effectively targeted food subsidies for very poor households may play a role in improving their calorie intake

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

food preferences and nutrition in rural bangladesh t he dietary choice of households near subsistence levels of nutrient intake is one of obvious policy importance in many countries such as bangladesh national goals are set in terms of nutritional intake and there is heavy intervention in the markets for foods however little is known about the manner in which food preferences vary with food expenditure and nutrient intake the design of efficient programs to aid nutritionally deficient households in attaining minimal levels of nutrient intake requires information on all ownand cross price elasticities for both target and non target groups the net effect of a food price subsidy on the consumption of food nutrients cannot be predicted without knowledge of the complete elasticity matrix results presented below demonstrate that substitution effects can be so strong that the subsidization of certain foods quite often reduces nutrient consumption in this study demand equations for nine foods which allow for extremely flexible consumer price response are estimated from the individual budgets of 5 750 rural bangladeshi households estimation at the household level is preferred because it more readily permits the incorporation of household composition variables into the demand analysis such as household size occupation and employment status that are typically lost in aggregation there is also a greater range and variation in expenditure levels than found in grouped data this is of particular importance in the study of nutritional well being as it is the poorest households which are of special interest moreover the household sample provides sufficient degrees of freedom to estimate a simple varying parameter model which requires the estimation of 270 parameters previous econometric analysis of income class specific dietary choice has been limited and not altogether satisfactory pinstrup anderson de londono and hoover 1976 estimated complete sets of price elasticities for different income strata using frisch s scheme in order to study the impact of changes in relative prices on nutrient consumption their results are suspect because of the assumption of want independence necessary for this methodology to be valid alderman and timmer 1980 who were also concerned with studying the relationship between food price policy and nutrient intake by income classes econometrically estimated separate price coefficients for each income group by including slope dummy variables in their demand equations for rice and cassava in indonesia the inclusion of these dummy variables revealed surprisingly large differences in compensated price response across income groups although their results support the notion that poorer households respond differently to prices than the rich the limitations of their data constrained them to consider only two foods and to specify changes in price response which are discontinuous with respect to income i the formulation and estimation of the food demand equations is discussed in section ii below section iii presents the results of the estimation and discusses the nutritional implications of movements in relative food prices and other exogenous variables section iv summarizes our findings

discrete equilibrium price dispersion an explicit solution of an equilibrium model with price setting firms and searching customers makes possible a number of comparativestatics predictions about how cost differences among firms search costs of customers and taxes will affect the mean and variance of the distribution of market prices another implication of the model is that a firm s demand depends on the difference between its price and the average price in the market

poverty and public policy the problem of poverty is particularly acute in india with 14 of the world s population we have the misfortune of having almost twice as large a share of the world s poor indeed as i shall presently underline the question of poverty and its amelioration has been at the center of our concerns from the beginning of our planning efforts almost four decades ago little therefore can be said on it that some distinguished indian economist has not already said in some ways therefore to talk on the design of public policy for poverty to an indian audience is to carry coal to newcastle or as the old saying goes to teach your grandmother how to suck eggs nonetheless i hope to provide a fresh perspective by putting the problem into an explicit analytical framework that permits alternative policy designs to be sharply defined and contrasted i also intend to draw on international experience to put our efforts and problems into both historical and comparative perspectives

crises food prices and the income elasticity of micronutrients estimates from indonesia the 2008 global food price crisis and more recent food price spikes have led to a greater focus on policies and programs to cushion the effects of such shocks on poverty and malnutrition analysis of the income elasticities of micronutrients and their changes during food price crises can shed light on the potential effectiveness of cash transfer and nutrition supplement programs this article examines these issues using data from two cross sectional household surveys in indonesia taken before 1996 and soon after 1999 the 1997 98 economic crisis which led to a sharp increase in food prices first using nonparametric and regression methods the article examines how the income elasticity of calories from starchy staples as a share of total calories differs between the two survey rounds second the article estimates income elasticities of important nutrients in indonesia the analysis finds that although summary measures such as the income elasticity of the starchy staple ratio might not change during crises this stability masks important differences across individual nutrients in particular income elasticities of some key micronutrients such as iron calcium and vitamin b1 are significantly higher in a crisis year than in a normal year yet the income elasticities of others such as vitamin c remain close to zero these results suggest that cash transfer programs might be even more effective during crises to ensure the consumption of essential micronutrients but to ensure that all key micronutrients are consumed nutrition supplement programs are also likely required jel classification codes i12 o12 d12 e31 keywords income elasticity crisis prices micronutrients vitamin c starchy staple ratio

a probit latent variable model of nutrition information and dietary fiber intake nutrition information and intake data for a sample of u s household meal planners are used to estimate the effects of fiber specific information on dietary fiber intake the information variables are measured using survey questions on fiber content of foods attitude toward consuming fiber rich foods and awareness of fiber health links the evidence confirms the influence of nutrition information on fiber intake household income meal planner age smoking status vegetarian status race and ethnicity are major determinants of both information and intake education exerts a sizable intake effect by enhancing the information level direct and indirect effects of exogenous variables are reported

agricultural household models extensions applications and policy this book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far the model assumes that households are price takers and is therefore recursive the decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor comparative results on selected elasticities are presented for a number of economies the empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive the book summarizes the implications of agricultural pricing policy for the welfare of farm households marketed surplus the demand for nonagricultural goods and services the rural labor market budget revenues and foreign exchange earnings in addition it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition nutritional status health saving and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings methodological topics primarily the data requirements of the basic model and its extensions along with aggregation market interaction uncertainty and market imperfections are discussed the most important methodological issues the question of the recursive property of these models is also discussed

nutritional status during an economic crisis evidence from russia between 1996 and 1998 russia experienced a spectacular decline in economic activity which was followed by a dramatic rebound between 1998 and 2000 we use panel data to examine the impact of variation in household resources on six dimensions of nutritional status distinguishing longer run from short term fluctuations in resources nutritional status is very resilient to short term variation in household resources gross energy intake adult weight and child stature change very little as expenditure deviates from its long run average longer run resources have a substantively large positive and significant effect on energy intake diet quality adult weight and child stature the evidence indicates that individuals and households are able to weather short term fluctuations in economic resources at least in terms of maintaining body mass and energy intake increased globalisation has resulted in many less developed countries becoming more integrated into world markets this integration carries both benefits and costs for the populations of those countries an oft cited cost is elevated risk of exposure to economic fluctuations which has been manifest in several spectacular economic crises across the globe in the last few decades there is however little evidence on the extent to which individuals and families are able to mitigate deleterious effects of these economic upheavals on their well being in spite of its importance for understanding the consequences of globalisation this article provides new evidence on this issue specifically we examine the relationship between several dimensions of nutritional well being and variation in household resources during the russian economic crisis in the late 1990s the economies of the former soviet bloc have been especially volatile since the transition to market based economies which began in the early 1990s nowhere has this been more true than in russia where in the last half of 1998 real gdp collapsed by around 30 and then rapid growth brought the economy back to its pre crisis level by 2000 the time path of changes in gdp is closely mimicked by changes in the incomes and expenditures of russian households using extremely rich longitudinal household survey data from the russian longitudinal monitoring survey rlms we examine the impact of these large fluctuations in household resources on nutrient intake and on anthropometric markers of nutritional status at the individual level in so doing we address an important issue in the literature regarding the extent to which households in low income settings are able

the economics of development a survey i the subject our definition of the subject will be the use of economic analysis to understand the economies of poor or developing countries this includes in particular how standards of living in the population are determined and how they change over time and further how policy can or should be used in the influence of these processes the definition contains in principle much or most of analytical methods in economics insofar as they can be put to use in the examination of the issues of interest this is as it should be but it poses a problem for a survey in a journal a comprehensive treatment is infeasible so we shall follow a different route the survey will focus on what i take to be the major themes and approaches which characterise the productive aspects of the subject there is therefore no pretence at being exhaustive the purpose is rather to highlight some of the advances many of these have been of real substance there are a number of possible purposes for a survey and it is important to be clear at the outset for whom it is intended what it is and what it is not this survey is addressed to economists and students of economics who know the tools of their trade but not necessarily how they have been applied to and fashioned for the analysis of the economics of developing countries it is a description of the ways in which problems can be productively formulated and approached in terms of examples chosen for their intrinsic importance and interest the vastness of the subject means that we have to be highly selective it does not seek to provide a summary evaluation of the current view of the appropriate response to immediate policy questions it is not a history of thought nor a research manifesto nor an attempt to adjudicate or settle the major debates where they arise naturally from the major purpose some judgements on these subjects will be offered but they do not themselves constitute the primary intent of this survey there are three lines of enquiry or sets of questions which have i suggest been distinctive of the most fruitful work in development economics they will

an analysis of childhood malnutrition in rural india role of gender income and other household characteristics there are controversies regarding the role of individual and household characteristics in childhood nutritional status measured by anthropometric indicators using a nutrition index based on weight for age of children in rural india the paper re examines this issue ordered probit estimates of nutritional status suggest female literacy improves the nutritional status of boys at the cost of girls while higher per capita current income improves that of both boys and girls though the impact is higher for boys however effect of income is not robust when we use instruments of longer run income but more income and literacy give more ways to discriminate between boys and girls

poverty and the forward falling labor supply function a microeconomic analysis abstract existing subsistence efficiency target income and limited aspiration theories impose a backward bending labor supply behavior on poor workers in less developed countries recent empirical studies of worker behavior in the unorganized sectors of ldcs contradict this view and report evidence of both a forward falling and an upward rising labor supply this study formulates an increasing elasticity of substitution utility function model to analyze the observed behaviors the function displays both nonhomotheticity and variable elasticity properties and is capable of generating labor supply curves with forward falling and upward rising segments while the upward rising supply is considered to be usual worker behavior the forward falling segment represents a below subsistence distress sale phenomenon and the subsistence income of the worker is implied to occur at the turning point joining the two segments of the supply curve econometric estimates of the utility and the labor supply functions provide support to the theoretical results

input choices in agriculture is there a gender bias summary this paper examines evidence of gender biases in the decisions of agricultural households utilizing data from international crops research institute for the semi arid tropics s village level studies in india 1975 85 the main empirical finding is that households with a high proportion of boys tend to use some agricultural inputs including fertilizers and irrigation services more intensively than households with girls this pattern is more pronounced among wealthier households but does not appear to be driven solely by bequest motives or male child labor productivity

bank lending and monetary transmission in the euro area to what extent does the availability of credit depend on monetary policy and does this relationship vary with bank characteristics based on a common source of balance sheet data for the four largest economies of the eurozone over the period 1999 2011 we find that the effects of monetary policy on bank lending are significant and heterogeneous in germany and italy which are characterized by a large number of banks but are weaker and more homogeneous in spain and france whose banking industry has a higher degree of market concentration in particular monetary policy appears to exert larger effects on cooperative and savings banks with lower liquidity and lesser capital in germany and savings banks with smaller size in italy our results highlight that the transmission of monetary policy over bank lending in the eurozone is highly heterogeneous from a policy perspective the increased large number of cooperative and savings banks which have had access during the last financial crisis to the refinancing operations of the european central bank bodes well for the improvement of the monetary transmission mechanism the analysis also suggests that competition policy measures aiming at reducing entry barrier might facilitate the transmission mechanism roberto a de santis and paolo surico

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

optimal intertemporal consumption decisions under the threat of starvation abstract this paper studies consumption and saving decisions over time in a life cycle model in which survival from one period to the next is endogenous survival probabilities depend on health which is a capital stock subject to depreciation and which can be augmented by consumption nutrition borrowing is ruled out in our model and we investigate optimal consumption decisions when income fluctuates at seasonal frequencies and when income follows a stochastic process among other results we show that understanding the pattern of income is necessary for understanding consumption decisions when survival is probabilistic and endogenous

the impact of demand and price expectations on the behavior of prices the effects of demand and price expectations on price behavior are analyzed using data from the manufacturing sector and a model formulated to pinpoint the demand oriented factors affecting prices and to incorporate price expectations as a direct influence on price behavior the expected normal demand is seen to have a strong and systemic influence on price behavior the expected normal level of new orders is found to be an adequate measure with sector data in general although some industries require more specification the effects of inventories and unfilled orders on prices are sporadic and across sectors and industries demand oriented forces are concluded to perform as well statistically as cost push determinants expectations concerning the current normal industry price level have a significant and consistent impact on price behavior this supports the idea that firms setting prices take into account their estimates of competitor s prices future price expectations appear to have little effect on current price information 15 references

trade association disclosure rules incentives to share information and welfare in this article i propose a monopolistic competition framework to analyze the effects of different disclosure rules used by trade associations on the incentives to share information and on the welfare of consumers firms and society this framework is appropriate whenever a single firm cannot influence aggregate market magnitudes and serves as a benchmark for the analysis of information pooling agreements abstracting from strategic considerations i report two main results first a policy of nonexclusionary disclosure destroys the incentives to share information while exclusionary disclosure preserves them second information sharing increases expected total surplus with cournot competition but decreases it with bertrand competition in the context of a quadratic normal model with demand uncertainty

asymmetries in the bank lending channel of monetary policy in the united states abstract we study the presence of asymmetries in the transmission of monetary policy in the united states we find that the bank lending channel is stronger when the federal reserve tightens monetary policy particularly when the monetary policy stance is expansionary

the poor and the social sectors during a period of macroeconomic adjustment empirical evidence for jamaica considerable uncertainty remains about the human impact of macroeconomic adjustment analysis of the impact of adjustment on the poor and on the social sectors is difficult because it involves evaluating a counterfactual situation in which households are affected by prices incomes and public services with the possibility of substantial substitutions all within an economywide framework with complicated concurrent and lagged interactions time series data for jamaica is utilized in this article to examine whether macroeconomic adjustment initiated in the early 1980s but intensified in 1984 85 was associated with significant deterioration in various indicators of health nutritional and welfare outcomes particularly among the poor although the authors find evidence of substantial cuts in governmental expenditures on social services there is little confirmation of significant short run deterioration in human capital indicators during the adjustment period

estimating the demand for calories in india this article examines the long run relationship between per capita calorie intake per capita income and food prices using aggregate data for india 1961 1992 cointegration analysis yields an income elasticity of calorie intake of 0 34 while the food price elasticity is insignificant thus economic growth in india as measured by increasing per capita income has significantly improved calorie intake future income growth can alleviate further inadequate nutrition however significant improvements in calorie intake cannot be made directly by food subsidies a further result is that calorie intake is granger caused by income and not vice versa income generation is unconstrained by calorie intake

determinants of dietary quality evidence from bangladesh summary whereas a large number of studies have been devoted to analyzing consumer demand for dietary quantity much less attention has been paid to the demand for dietary quality to address this gap in the literature this paper explores the determinants of dietary quality in bangladesh using data from a nationally representative household expenditure survey conducted in 2000 we find that while male education plays a positive role female education has a substantially stronger influence further female household headship is associated with lower dietary quality than male headship thus promoting female education and addressing the unique constraints faced by female headed households with respect to diet quality could be a significant policy instrument for addressing food insecurity in bangladesh

nutrient demand and the allocation of time evidence from guam this paper presents an econometric study of nutrient intake in guam which explicitly accounts for household time allocation and household capital variables the empirical framework is based on a household production model of nutrient consumption food expenditure and the allocation of time between labour leisure and food preparation activities the study finds evidence that 1 capital and wage variables have significant impacts on households nutrient demands 2 income wage and educational status have very different effects on the nutrient choices of low calorie households than on the nutrient choices of high calorie households and 3 a family s participation in the food stamp programme leads to higher levels of food expenditure but this impact is attributable to the purchase of more costly taste characteristics in food rather than to the purchase of more nutritious foods

does bank ownership affect lending behavior evidence from the euro area abstract we analyze the differences in lending policies across banks characterized by different types of ownership using micro level data on euro area banks during the period 1999 2011 to detect possible variations in bank lending supply responses to changes in monetary policy our results identify a general difference between stakeholder and shareholder banks following a monetary policy contraction stakeholder banks decrease their loan supply to a lesser extent than shareholder banks a detailed analysis of the effect among stakeholder banks reveals that cooperative banks continued to smooth the impact of tighter monetary policy on their lending during the crisis period 2008 2011 whereas savings banks did not stakeholder banks propensity to smooth their lending cycles suggests that their presence in the economy has the potential to reduce credit supply volatility

nutritional adaptations of linear programming for planning rural development linear programming can help plan rural development if the income maximization and least cost diet models are integrated within the resource and management limitations of small scale representative farms seven modifications adapt linear programming to subsistence households caveats in this context include risk level of nutritional awareness production scale and result sensitivity through six model formulations for a representative nepalese farm linear programming identifies the most nutritious and profitable production patterns trade offs between nutrition and income and the costs of constraints relating to levels of credit market availability and human capital development

food preference poverty and the nutrition gap in recent decades widespread poverty has been observed in the developing economies studies probing the relationship of development to income distribution or poverty suggest either no development effect on the extent of poverty or a widening of inequality of incomes during the initial stages of development 2 a recent study by dandekar and rath of poverty in india showed the prevalence of poverty in both rural and urban areas after nearly three five year plans although these plans enabled india to achieve a sustained high rate of growth 3 other studies just preceding and following confirmed and extended the major conclusion of dandekar and rath s study 4 while income distribution studies relate to the extent of relative poverty studies similar to dandekar and rath s relate to absolute poverty in the latter the measurement of poverty is related to calorie intake levels in at least one study it is related to a collection of basic goods recent studies at the international level give evidence of poverty in the past decade and project a further spread in the next they too have used the calorie based poverty line 6 in this paper i maintain that calories or other nutrients taken singly or together measure only one attribute of food another is its taste the demand for food is a joint demand for these attributes and others like bulk which gives a sense of fullness i maintain that to concentrate on nutrition or calories alone leads to inaccuracy in measuring the extent of poverty we must ask therefore what role food preferences play in food consumption and nutrition intake my attempt is to understand food habits especially at low income levels although measurements are given regarding food preferences

the demand for food quality in rural china many studies of food demand do not use actual prices but unit values obtained by dividing expenditures by the quantity consumed this can bias empirical analyses because unit values are not exogenous market prices they reflect household food quality choices within each food category this article develops a framework for assessing the resulting bias in income and price elasticities of demand and applies the framework to data for rural china empirical results indicate that households in rural china tend to consume higher quality food as income increases with a greater sensitivity to income for basic foods than for luxury foods copyright 2009 oxford university press

welfare grants and their impact on child health the case of sri lanka summary this paper asks whether an exogenous increase in income in the context of a poverty alleviation program has an impact on child anthropometric outcomes the study looks at the samurdhi program in sri lanka and uses household data for 1999 2000 using propensity score matching to account for selectivity bias the paper finds that samurdhi improves the height for age z score of a child from a grant receiving family by roughly 0 40 standard deviations with the impact driven mainly by children between six and 36 months of age compared to if they did not receive the grant it also improves weight for height z scores by around 0 45 standard deviations of children aged 36 60 months these results are important for sri lanka where child nutrition is a cause for concern

how do obese people afford to be obese consumption strategies of russian households this article investigates the extent to which russian households that differ in their members weight status adjust their food consumption differently when their economic resources change using household panel data from the russia longitudinal monitoring survey rlms from 1995 to 2005 we estimate total expenditure elasticities of food expenditures food quantities and food quality for normal weight overweight and obese households respectively the expenditure elasticities of quality derived for obese households for meat bread fruits and dairy were found to be 15 20 higher than those of normal households hence a change in economic resources causes obese households to adjust the quality of purchased foods significantly more flexibly than normal weight households only few differences were found for quantity and expenditure reactions our results emphasize that policies aiming to reduce obesity should consider deviations in consumption behavior of normal and obese consumers in terms of quality

can targeted food programs improve nutrition an empirical analysis of india s public distribution system abstract despite the widespread belief that a substantial assault on poverty requires targeting scarce resources toward the poor practitioners frequently claim that targeted programs deliver fewer benefits to poor households than do universal programs this article evaluates this concern through an analysis of india s targeted food distribution program the public distribution system it first examines the case for targeting by assessing the responsiveness of caloric intake to the amount of the food grain subsidy a low elasticity suggests that improvements in nutrition may require large subsidies and hence a targeted program it then examines whether targeting adversely affects the probability of poor households participating in the program the empirical analysis identifies the effect of the program by combining time varying policy changes in the value of the program with cross sectional variation in program benefits generated by variation in market prices the results confirm the low responsiveness

program conditionality and food security the impact of progresa and procampo transfers in rural mexico this paper examines the progresa and procampo cash transfer programs in mexico and evaluates their impact on household food security and nutrition these two programs differ in their targeting and design progresa is aimed at women and program conditionality is linked to current consumption and human capital investment procampo benefits male farmers and program conditionality is linked to agricultural production the main question addressed by the paper is whether a cash transfer program geared to agricultural production can have the same impact on food security as a cash transfer program geared to consumption through purchases our results suggest that monetary payments linked to a productive asset land can have as large or larger impact on food security as cash transfers not linked to a productive asset we show that both programs boost total food consumption and caloric intake in similar proportions however increased food security is achieved through different channels for progresa through purchases while for procampo through investment in home production this suggests that the choice of program design depends on objectives beyond total food consumption and caloric intake such as consumption from specific food categories diversity of food consumption investment in agricultural production and the degree of access to retail food markets

measurement and determinants of rural poverty household consumption patterns and food poverty in rural sudan abstract a logit model and engel curves are used to study the determinants of food poverty and composition of household consumption among the tenant farmers of the rahad scheme in sudan where land is equally distributed the data support the permanent income hypothesis whereas engel s assumption of declining food shares with increased total spending did not hold for the present sample the logit analysis provides strong evidence for the important influences of better access to productive assets other than land smallersized families higher non farm earnings and farming experience on reducing the probability of food poverty on the scheme policies directed towards the provision of better family planning education extension increased on and off farm employment and improved infrastructure for higher labour mobility can make for effective poverty alleviation programmes in this sector

can drought increase total calorie availability the impact of drought on food consumption and the mitigating effects of a conditional cash transfer program abstract this study uses the panel data of a randomized experiment from the mexican progresa program to evaluate the impact of drought on total calorie availability and the mitigating effects of progresa on food consumption in periods of drought drought reduced total expenditures and total food expenditures but increased the total availability of calories this paradox can be explained by the impact of drought on the composition of calories that is it reduced the consumption of expensive calories in such foods as vegetables fruits and animal products but increased calories consumed from cheaper sources such as grains this study finds that progresa can completely mitigate the negative effects of drought on calorie availability from vegetables fruits and other sources however progresa cannot mitigate the impact of drought on calories available from grains the analysis also shows that during drought households who increase their consumption of grains get them mainly from purchased sources rathe

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

testable competing hypotheses from structure performance theory efficient structure versus market power this paper provides a structure performance theory that can accommodate leading firm efficiency as well as several competing market power hypotheses the author derive s testable implications distinguishing the simple collusion product differentiation and scale economy hypotheses from the innovative lea ding firm alternative it is shown that recent evidence of a positive market share price cost margin pcm relationship and a nonpositive concentration pcm relationship can reject the scale economy and simpl e collusion hypotheses in homogeneous product markets unfortunately this same evidence cannot reject the product differentiation hypothe sis in favor of leading firm efficiency copyright 1988 by blackwell publishing ltd

fuelling calorie intake decline household level evidence from rural india summary in india average calorie intake has declined even as real monthly expenditure has increased since cross sectional evidence suggests a positive relationship between the two variables the trend emerges as a major puzzle using household level data from four recent rounds of national sample survey data on consumption expenditure and a novel instrumental variable estimation strategy we find that rising expenditure on non food items is one of the factors that has led to the calorie intake decline we provide causal evidence for such a food budget squeeze in the case of one type of non food item viz expenditures on cooking fuel

determinants of food consumption in rural sierra leone abstract this paper reports the application of a quadratic expenditure system with demographic variables to the household consumption leisure choice component of a household firm model a system of seven commodities is estimated including five foods non food and leisure appropriate for such a level of disaggregation a demand system is used the quadratic expenditure system which allows for a flexible relationship between full income and commodity expenditures without sacrificing parsimony in parameters demographic data on households are explicitly incorporated into the model allowing for a richer specification than can be achieved by using per capita variables the data are from a cross section survey of households in rural sierra leone price variation exists by region permitting estimation of a complete demand system engel curves are found to be significantly non linear with marginal expenditure on rice the major staple declining with higher income most foods are found to be reasonably price responsive with sizeable own price substitution effects declining with higher income aggregate labor supply is found to be price inelastic

is relationship lending still a mixed blessing a review of advantages and disadvantages for lenders and borrowers relationship lending is a common lending technology that is assumed to bring several benefits to small medium enterprises smes and to financial institutions that adopt it notably it could reduce information asymmetries permitting banks to offer better credit terms to the borrower however it also entails some costs for both sides the empirical evidence so far has not been conclusive in determining under what conditions relationship lending can be beneficial or harmful most of the studies suggest that smes that engage in relationship lending benefit from more credit availability especially during a financial crisis and lower interest rates this occurs when they are served by small banks are geographically close to the lender when the bank is adequately decentralized and when it is the dominant creditor of the firm however under certain circumstances banks can extract rents from the borrower or be captured by him in addition the consequences and the future of relationship lending will be remarkably affected by the level of competition among banks their ownership structure the regulatory framework and the business model that banks will have to adopt accordingly

does bank opacity affect lending abstract examining a sample of bank holding companies in the united states we find that opacity has a negative effect on bank loan growth this effect is more pronounced for banks that are more reliant on wholesale funds a further analysis of the relationship between opacity and wholesale funds confirms our hypothesis that opacity negatively affects lending via a wholesale funding channel moreover our results suggest that the negative effect of opacity on lending is less pronounced for banks with stronger capitalization we also show that this effect was stronger during the 2007 2009 financial crisis and is mitigated by a high gdp growth rate indicating that a strong weak macroeconomic condition tends to mitigate aggravate such an effect

nutrition health birth order and seasonality intrahousehold allocation among children in rural india abstract nutrients available to children are determined largely by intrahousehold allocations there are a number of reasons why birth order may affect these allocations a model is developed to estimate critical parameters of parental preferences regarding the allocation of nutrients among their children latent variable estimates for rural south india indicate that parental preferences have productivity equity tradeoffs and parents favor older children the productivity equity tradeoff however is much less for the lean season therefore when food is scarcest parents follow more closely a pure investment strategy exposing their more vulnerable children to greater malnutrition tisk

evaluating familial support for the elderly the intrahousehold allocation of medical expenditures in rural pakistan introduction in this article i examine the determinants of medical expenditures on the elderly in rural pakistani households analyzing in particular the dependence of such expenditures on the economic contribution of the elderly to household income the results for older males are contrasted with those for younger males improved life expectancies in the south asian economies as in other developing economies have generated new policy interest in the economic status of the elderly there is however little empirical evidence on this topic while the scant research on the elderly in south asia undoubtedly reflects the fact that they represent one of the smallest demographic groups in these economies it also reflects the widespread belief that they are well provided for by the intergenerational households where the vast majority of them reside with their adult children however this assumption has been questioned by a number of scholars who find that medical expenditures on the elderly are closely correlated with the elderly s individual incomes and wealth household data from pakistan support such claims data on individual medical expenditures and days of illness are available from two household surveys a panel data set collected by the international food policy research institute ifpri and from the pakistan living standards measurement survey lsms both data sets reveal a strong correlation between the number of days of illness reported by adult males and age leading one to expect a similarly strong correlation between medical expenditures and age instead the ifpri data yield a correlation that is less than one would expect given the relationship between illness and age the lsms data set which provides information on many more

monopolistic competition aggregation of competitive information and the amount of product differentiation consider an industry with a large number of homogeneous firms each firm s profits are a function of its own strategy and the strategies the other firms select suppose other firms strategies enter into each firm s profit function only through one or more statistics for example average price in the market may parameterize every firm s profit function we prove that as a general rule the industry s firms will in equilibrium follow at most m 1 distinct strategies where m is the number of statistics by which competitors strategies affect each firm s profits

biological technology and agricultural policy an assessment of azolla in philippine rice production concerns about external debt and energy security have motivated several developing countries to develop biological technologies to substitute for petrochemical inputs this paper examines the economic feasibility of azolla as a source of nitrogen in philippine rice production green manuring with azolla is found not to be cost effective substantial savings from intercropping with azolla can be realized only if the cost of nitrogen from azolla is compared with the price of nitrogen from ammonium sulfate but not if urea is used as the basis of comparison farmers would benefit more from liberalization of import controls on urea additional research is needed to develop appropriate chemical saving systems before investing heavily in extension

bank credit rates across the business cycle evidence from a french cooperative contracts database abstract financial theory indicates that bank firm relationships can induce a hold up problem resulting in higher interest rates yet only weak empirical confirmation of this result exists moreover the potential influence of the business cycle on the bank firm relationship still requires empirical consideration with a unique contracts data set collected from a french cooperative bank between 1996 and 2009 this study shows that the effects of bank firm relationships on the credit rate depend on economic conditions and that the hold up problem is at play only during economic recessions

biotechnology for rural nutrition abstract this article evaluates the introduction of algal biotechnology as a nutrition intervention in rural south india in terms of its benefits costs and acceptability to the tastes and income of rural households data were collected from a whole village study and developments in the theory of the economics of tastes are used to analyse the socioeconomic acceptance of algal supplements among the study households the results indicate that the algal food supplement is highly cost effective in providing adequate protein and other micronutrients however the absolute deviation between actual and optimal intake of algal food increased with higher income class several policy implications for food and nutrition interventions in developing countries are derived

does it matter how we survey demand for food evidence from kenya and the philippines abstract this article examines the reliability of food quantity information collected from expenditure surveys and finds that measurement errors will very often be systematically correlated with income such that the response of food intakes to increases in income is seriously overstated this may be firstly because food quantities are not measured independently of income if total expenditures are the proxy used for income and secondly because food transfers in the form of guest and hired worker meals are under recorded these biases are illustrated using household surveys from kenya and the philippines

calories and poverty during a prolonged crisis abstract we study how calorie intake changes during prolonged crises by studying the calorie intake of households when exposed to short term and long term income and price shocks we use data from household surveys of mexican households during the income and price crises periods of 1994 to 1998 and 2006 to 2010 our focus is on low income mexican households those with the lowest 25 of expenditure per capita there is little effect on calorie intake following an income decline in the short run once households are exposed to reduced incomes for a longer period calorie intake falls households are able to weather short term fluctuations in income by shifting consumption to food items that are cheaper per calorie such as staple foods by consuming more foods at home instead of outside the home and by postponing expenditures on durable and semi durable goods when exposed to the income shock over a longer period of time we posit that households are not able to defer durable and semi durable purchases any more so their calorie consumption drops our results suggest that mexican households may be able to sustain calorie intake when faced with an income shock but it is less likely that they are able to do so if the income shock persists the government may want to support poor constituents when they are faced with prolonged crises

food quality calories and household income the authors investigate the relationship between calories food quality and household per capita expenditure using regression and semi parametric methods on a sample of poor households from rural mexico where programa de apoyo alimentario pal a targeted nutritional program is operating the semi parametric method yields an estimate of the elasticity between calorie and expenditure of 0 39 below the median and 0 28 above the corresponding estimates of the elasticity of the calorie price are 0 48 below the median and 0 45 above the authors also examine the extent to which the expenditure elasticity of the calorie price is explained by substitution between and within major food groups it is found that there is a very high incidence of substitution within cereals especially for poor households and that between group substitution explains at most 59 percent of the income elasticity for food quality these estimates suggest that the potential of a cash transfer program to have a positive impact on the food diversity and the nutritional status of households is quite limited the paper is organized as follows section one gives introduction section two describes the data the econometric specification and estimation approaches used and presents and discusses descriptive evidence on the intake of calories and the price of calories in the sample the relationship between calories the cost of calories and household expenditure is studied using regression and semi parametric methods in section three section four concludes by summarizing the policy implications of findings

biological measures of the standard of living when economists investigate long term trends and socioeconomic differences in the standard of living or quality of life they have traditionally focused on monetary measures such as gross domestic product which has occupied center stage for over 50 years in recent decades however scholars have increasingly recognized the limitations of monetary measures while seeking useful alternatives this essay examines the unique and valuable contributions of four biological measures life expectancy morbidity stature and certain features of skeletal remains to understand levels and changes in human well being people desire far more than material goods and in fact they are quite willing to trade or give up material things in return for better physical or psychological health for most people health is so important to their quality of life that it is useful to refer to the biological standard of living biological measures may be especially valuable for historical studies and for other research circumstances where monetary measures are thin or lacking a concluding section ruminates on the future evolution of biological approaches in measuring happiness

the benefits of lending relationships evidence from small business data this paper empirically examines how ties between a firm and its creditors affect the availability and cost of funds to the firm we analyze data collected in a survey of small firms by the small business administration the primary benefit of building close ties with an institutional creditor is that the availability of financing increases we find smaller effects on the price of credit attempts to widen the circle of relationships by borrowing from multiple lenders increases the price and reduces the availability of credit in sum relationships are valuable and appear to operate more through quantities rather than prices

the intrahousehold demand for nutrients in rural south india individual estimates fixed effects and permanent income good estimates of nutrient intake responses to prices and income are very useful for the evaluation of the numerous efforts to improve nutrition in many developing countries through pricesubsidy and income generation policies we discuss three problems in standard estimates of these responses and then illustrate their implications for nutrient demand relations for a poor sample from rural south india 1 intra household nutrient allocations usually are ignored in this case nutrient intakes for females systematically have algebraically lower price elasticities than do those for males which may leave the females particularly vulnerable at times of food shortages 2 unobserved fixed effects may bias the estimates of responses to observed variables in this case not only the community fixed effects on which the previous literature has focused but also household and individual fixed effects are important failure to control for them results in substantial algebraically upward biases in many estimated price responses 3 most previous studies use current instead of permanent income which a priori may account for the low estimated income elasticities in this case however the use of permanent income does not change the conclusion that the nutrient intakes responses to income are quite small

why bank credit policies fluctuate a theory and some evidence in a rational profit maximizing world banks should msdntain a credit policy of lending if and only if borrowers have positive net present value projects why then are changes in credit policy seemingly correlated with changes in the condition of those demanding credit this paper argues that rational bank managers with short horizons will set credit policies that influence and are influenced by other banks and demand side conditions this leads to a theory of low frequency business cycles driven by bank credit policies evidence from the banking crisis in new england in the early 1990s is consistent with the assumptions and predictions of the theory

the indian public distribution system as provider of food security evidence from child nutrition in andhra pradesh abstract we study whether a sudden increase of the price of rice supplied by the indian public distribution system in andhra pradesh a large indian state had a negative impact on child nutrition a few months after the price increase a health survey started to record weight for a large sample of children the data collection continued for several months so that children measured later lived for a longer period of time in a less favorable price regime using different estimation techniques we find that longer exposure to high prices are not accompanied by worse nutritional status as measured by weight for age

the effect of cash transfers and household vulnerability on food security in zimbabwe abstract we study the impact of the zimbabwe harmonized social cash transfer hsct on household food security after 12 months of implementation we investigate determinants of food security as measured by a well known food security scale the household food insecurity access scale hfias and as measured by value of household food consumption composed of own production market purchases and gifts received we find that several dimensions of household vulnerability correlate more strongly with the food security measure than with food consumption labor constraints which is a key vulnerability criterion used by the hsct to target households is an important predictor of the food security score but not food consumption and its effect on food security is even larger during the lean season impact analysis shows that the program has had statistically significant impacts on food security and diet diversity scores but null to low impacts on food consumption however aggregate food consumption hides dynamic activity taking place within the household where the cash is used to obtain more food from the market and rely less on food received as gifts the cash in turn gives beneficiaries greater choice in their food basket which improves diet diversity

the determinants of nutrient intake results from western india abstract this paper presents and tests a model of the determinants of nutrient intake the model is based on an identity whereby calorie intake per adult equivalent can be expressed as a function of total expenditure the share of food in the budget a unit value index an expenditure efficiency index and household composition these endogenous variables are in turn expressed as a function of exogenous variables such as assets demographic factors and agricultural technology the results help to explain the large variance in calorie intake at a given level of income and suggest that interesting compensatory behavior occurs by households

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

price policy and food consumption in urban mali abstract this study investigates the food consumption patterns of different income classes in urban areas of mali in order to assess the probable effects on dietary adequacy of the expected increase in the consumer price of rice brought about by food policy reform initiated in 1981 the results are to a degree counterintuitive demonstrating that understanding consumption patterns and their determinants is critical to informed policy making
