income inequality and growth does the relationship vary with the income level abstract for three different specifications of a cross country growth model the coefficient of initial income inequality is remarkably similar for high and low income countries contrary to some recent suggestions in the literature but varies markedly across models

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

life is unfair in latin america but does it matter for growth summary i analyze the effect of inequality on economic growth in latin america where inequality is measured as the area of family farms as a percentage of the total area of agricultural holdings using data from 18 latin american countries during 1960 2004 i find that inequality has a nonlinear effect on economic growth overall for the countries included in this analysis the share of family farms has a positive significant effect on economic growth these findings are robust to controlling for several factors using a different indicator of inequality land gini and addressing for endogeneity

social security public education and the growth inequality relationship abstract we study how the relationship between economic growth and inequality depends upon the levels of funding of two of the largest government programs public education and social security we do this in the context of an overlapping generations economy with heterogeneous agents where the government collects a tax on labor income to finance these programs we show that in our model an increase in government spending on social security reduces income inequality and can have a non monotonic effect on growth when the initial level of social security funding is low as is the case in most poor economies then its increase will enhance growth when its funding level is high as is typical for developed countries we show that its further increase can slow down growth while reducing income inequality these results obtain regardless of whether the increase in social security funding is financed by a tax increase or by cutting the public education budget we also find that the effects of increasing the level of public education expenditures or the overall size of the government budget holding the budget composition fixed are characterized by similar non monotonic growth inequality relationships

a hedonic approach to estimating the supply of variety attributes of a subsistence crop the article extends the household hedonic model by estimating a supply function for variety attributes of a subsistence crop in a developing economy the model is applied to bananas in uganda making use of disaggregated data on variety specific farm gate banana bunch prices and attributes while accounting for the semisubsistence nature of banana producing households the article is motivated by the need to understand the attribute trade offs made by farmers at the farm gate in light of targeted variety improvement efforts and their impact on banana markets whether variety improvement will pay off at the market level requires a more detailed examination of the relative worth of banana attributes within the structure of consumer preferences and production technologies related to bananas in uganda the results confirm the importance of consumption and production attributes in selling behavior quality and bunch size are found to be complements at the farm gate banana bunches that capture a premium at the market will be those that provide bundles of desirable consumption and production attributes simultaneously by revealing important price attribute relationships the findings provide guidance for crop improvement efforts and diversification choices while taking into account implicit market signals for output attributes

inequality and growth in the united states why physical and human capital matter we investigate the relationship between economic growth and top income inequality under the influence of human and physical capital accumulation using an annual panel of u s state level data our analysis is based upon the unified framework offered by galor and moav 2004 while the empirics account for cross section dependence parameter heterogeneity and endogeneity in nonstationary series we conclude that changes in inequality do not influence growth neither in the short run nor in the long run in the united states as a whole in the 1929 2013 period our findings are robust to the inclusion of overall income inequality measures these findings provide support for the theoretical prediction of the unified theory of inequality and growth according to which the growth effect of inequality becomes insignificant in the latest stages of economic development that the united states experiences during our period of investigation therefore future policies aiming at moderating the concentration at the upper end of income distribution are not likely to have adverse growth consequences in developed countries such as the united states jel i21 o47 c23

effects of food prices and consumer income on nutrient availability economic factors such as food prices and consumer income affect food choices with consequences for the availability of nutrients a new research model is developed to estimate how the availability of 28 nutrients would change as consumers alter their food purchases in response to changes in food prices and income through the interdependent food demand relationships

is inequality harmful for growth comment endogenous growth models have reignited interest in institutional and path dependencies in the economic growth process one reason for the interest in endogenous growth models is that they may explain why countries consistently grow at different rates in this vein it has been recently proposed that greater economic inequality reduces future economic growth an important paper in this literature is by torsten persson and guido tabellini 1994 who will be referred to as pt pt s model shows why it is reasonable to expect a negative relationship between inequality and future economic growth moreover their empirical evidence is consistent with their contention if pt s findings are robust to other data sets there would be important policy implications for example they imply that policy makers should not only be concerned with the distributional implications of government policies for political and social reasons but also because income distribution has long run effects on economic growth this indicates that greater u s income inequality since the early 1970 s may have resulted in lower subsequent economic growth however pt s results are somewhat fragile to various specifications suggesting that they should be replicated with different data sets and over different time periods pt p 617 with these implications in mind this study employs data from a panel of u s states to further explore the relationship between economic growth and income inequality in what follows section i summarizes pt s study and discusses how this comment extends their findings the empirical implementation and results in section ii directly examine the link between overall income inequality and growth section iii expands the analysis to alternative measures of income distribution and government policy one emphasis in section iii is the distinction between how the overall income distribution especially at the tails influences economic growth from how the relative well being of the median voter affects economic growth section iv provides some concluding discussion

determinants of the intrahousehold allocation of food in the rural philippines this study shows that the opportunity cost of time for husbands and wives can affect the intrahousehold distribution of food in a developing country equations which explain the relative allocation of calories within households were estimated for husbands wives and children with data for the rural philippines the estimating equation is derivable from both a joint household utility function and a bargaining model because the same households were included in the four survey rounds the various observations for a given individual were averaged for each variable in the estimation procedure wages were estimated using the heckman approach

educational screening by certificates an empirical test this paper argues that the relevant test of wage screening effects should be based on educational certificates rather than years of schooling this is because information conveyed to firms about individual productivity through years of schooling is not sufficiently refined for making individual wage offer decisions although it may be useful for making hiring decisions

income inequality tax policy and economic growth we investigate how the reduction of income inequality through tax policy affects economic growth taxation at different points of the income distribution has heterogeneous impacts on households incentives to work invest and consume using us state level data and micro level household tax returns over the last three decades we find that reducing income inequality between low and median income households improves economic growth however reducing income inequality through taxation between median and high income households reduces economic growth these asymmetric economic growth effects are attributable both to supply side factors i e changes in small business activity and labour supply and to consumption demand

multiple measurements of u s income inequality using 1980 state census data the gini ratio theil index coefficient of variation atkinson measure four values and nelson index as separate measurements of income inequality are regressed with nineteen ses variables traditionally found significant with gini in past research the standard deviation of educational attainment is dominant among all independent variables as the strongest predictor of inequality mean family income dominant in prior research is a distant second in predictiveness more diversity than commonality is evident among the nineteen ses variables as they predict income inequality measured by the eight different techniques copyright 1988 by mit press

nutrient availability food costs and food stamps nutrient consumption patterns of low income households were analyzed using data from the special low income component of the 1977 78 nationwide food consumption survey a system of simultaneous equations for estimating food cost and diet component availability levels in home food supply was applied the derived reduced form showed that food stamp program participation had a positive impact on diet component availability levels impacts of other socioeconomic variables examined for diet component availability were generally larger than those for program participation and income diet component availability levels were relatively constant across households with different income and food stamp program bonus levels

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

a refinement of the relationship between economic growth and income inequality there is mixed evidence in the literature of a clear relationship between income inequality and economic growth most of that work has focused almost exclusively on developed economies in what we believe to be a first effort our emphasis is solely on developing economics which we classify as high income and low income developing countries hidc and lidc we make such distinction on theoretical and empirical grounds empirically the world bank has classified developing economies in this manner since 1978 the data in our sample are also supportive of such classifications we provide theoretical scaffolding that uses asymmetric credit constraints as a premise for separating developing economies in such a way we find strong evidence of a negative relationship between income inequality and economic growth in lidc to be in stark contrast with a positive inequality growth relationship for hidc both correlations are statistically significant across multiple econometric specifications using international

surviving the great recession the influence of income inequality in us urban counties abstractsurviving the great recession the influence of income inequality in us urban counties regional studies while there has been extensive research on the role of income inequality in economic growth there has been less investigation as to the role of income inequality on economic resilience this paper addresses the relationship between income inequality and resilience by evaluating the vulnerability of urban counties in the united states entering recession between 2006 and 2010 and tests whether income inequality contributes to their probability of recession survival a cox proportional hazards model is used to determine factors contributing toward urban counties resilience to the external shock of the great recession the research is focused on the relationship between the level of income inequality in a county and its recession risk it is found that areas with increased income inequality entered recession earlier

no condition is permanent middle class in nigeria in the last decade the economic debate on existence and definition of the middle class has become particularly lively in many developing countries despite this growing interest the identification of the middle class group in these countries remains quite challenging building on a recently developed framework to define the middle class this paper tries to estimate the nigerian middle class size in a rigorous quantitative manner by exploiting publicly available panel data the expenditure associated to a 10 percent probability of falling into poverty is estimated and this is used as the middle class threshold for nigeria the threshold expenditure for the middle class in nigeria is found to be 378 39 naira per capita per day 2010 ppp relying on this threshold and through survey to survey imputation the size of nigeria s middle class in 2003 is also estimated the results show that there has been considerable improvement on the size of the middle class and poverty reduction between 2003 and 2013 poverty decreased between 2003 and 2013 from 45 to 33 percent while the middle class increased from 13 percent to 19 percent nevertheless the results still paint a heterogeneous picture of poverty and the middle class in nigeria where the largest portion of the population although above the poverty threshold continues to live with average or high vulnerability to poverty

income inequality financial development and macroeconomic fluctuations we examine the relationship between income inequality and variability in aggregate consumption growth in high income countries greater income inequality appears to be associated with more volatility in consumption growth whereas in lower income countries higher levels of income inequality tend to be associated with less volatility we present evidence that variability in real gdp growth is also related to income inequality in the same way our results suggest that the level of financial development may help to explain why the distribution of income affects the short run variability of consumption and output differently in high income countries than in low income countries

progressive tax and inequality in a unionized economy in this paper we develop a heterogeneous agent endogenous growth model of a unionized economy with distinct progressive tax schedules on labor and capital income with time preference heterogeneity the effective labor force balanced growth and income inequality are endogenously determined and these interact with each other a reduction in the degree of progressive labor tax yields a double dividend in terms of reducing income inequality and boosting economic growth while capital income progressivity displays the usual growth inequality trade off particularly the double dividend effect becomes more pronounced when unionization is declined or trade unions become more wage oriented leading to the so called cheshire cat phenomenon

giffen goods and the law of demand the paradoxical aspect of the giffen paradox is the inability of demand theory to explain why giffen goods are apparently so rare the resolution of the paradox arises from the distinction between the shape of market demand curves and the sequence of equilibrium prices that will be observed in markets in which quantity supplied changes the sense in which the giffen case is unlikely to occur is that the probability of identifying a giffen good is less than the probability that such a good exists

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

the effect of the value of time on food consumption patterns in developing countries evidence from sri lanka this study shows that the opportunity cost of women s time can affect household food consumption patterns in developing countries demand equations for rice bread and the ratio of bread to total cereal consumption are estimated for urban sri lankan households the demand specification which is based on the new household economics includes as explanatory variables the woman s estimated market wage and the household s full income and alternatively observed income wages are estimated using the heckman procedure to correct for sample selection bias

the design of optimal education policies this paper studies the education policy chosen by a utilitarian government in the model households differ in their income and in their children s ability income is observed by the government but ability is private information households can use private education but cannot borrow to finance it the government can finance education with income tax but at the cost of blunting the individuals incentive to exert labour market effort the optimal education policy we derive is elitist it increases the spread between the educational achievement of the bright and the less bright individuals compared to private provision it is also such that the education received by less bright individuals depends positively on their parental income finally the optimal education policy is input regressive in the sense of arrow 1971 quarterly journal of economics 38 175 208 households with higher income and brighter children contribute less in tuition fees towards the cost of the education system than households with lower income and less bright children

inequality and growth in the united states evidence from a new state level panel of income inequality measures i introduction rising income inequality in the united states over the past quarter century is well documented see e g gottschalk 1997 krueger 2003 levy and murnane 1992 piketty and saez 2003 whether and by how much this change in inequality is associated with a change in economic performance is an important question yet recent empirical work has been largely inconclusive positive relationships between income inequality and economic growth have been found by partridge 1997 2005 using a panel of states and by forbes 2000 using a panel of countries empirical work by panizza 2002 and quah 2001 however has found little or no stable relationship between inequality and growth the results appear to be extremely sensitive to the econometric specification additionally barro 2000 has found evidence that the relationship is nonlinear with inequality being positively related to growth among wealthier countries like the united states but negatively related to growth among low income countries much of this recent empirical literature was initiated by the important work of deininger and squire 1996 who constructed a large cross national panel of inequality measures containing several time series observations for each nation spaced over multiple decades a parallel empirical literature also emerged using u s state level data with income inequality measures typically spaced at 10 yr intervals see e g panizza 2002 partridge 1997 2005 both the state level and the cross national empirical literatures benefited by exploiting the more advanced panel data econometrics afforded by the large n small t panel dimensions in this paper we offer a new more comprehensive panel of state level income inequality measures and use this panel to reevaluate the empirical inequality growth relationship 1 this panel has the unique feature of being large in both n and t with annual observations of the 48 contiguous states for the entirety of the postwar period 1945 2004 for nearly all the states in the panel the share of income held by the top decile experienced a prolonged period of stability after world war ii followed by a substantial increase during the 1980s and 1990s these state level trends appear to closely replicate the overall trends in aggregate u s inequality found by piketty and saez 2003 exploiting the large and balanced size of our inequality panel we explore the long run relationship between inequality and growth via three alternative dynamic panel error correction estimators the fixed effects fe estimator the mean group mg estimator of pesaran and smith 1995 and the pooled mg estimator of pesaran shin and smith 1999 the greater homogeneity of state level data helps mitigate the difficulty in adequately capturing structural differences across international panels of earlier studies such as forbes 2000 and barro 2000 corruption levels labor market flexibility tax neutrality tradition of entrepreneurship and many other factors are only poorly measured if at all barro 2000 1011 and these sources of heterogeneity are much more likely to contribute to omitted variable bias across countries than across states the results from our analysis indicate that the long run relationship between the top decile share of income and economic growth is positive in nature moreover an evaluation of several alternative income inequality measures suggests that this positive relationship is driven primarily by the concentration of income in the upper end of the income distribution the structure of the paper is as follows section ii presents the new panel of annual state level inequality measures and includes an important discussion of its key limitations section iii then offers an empirical investigation on the impact of income inequality on the growth rate of real income per capita finally section iv offers a brief set of conclusions

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

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

native american obesity an economic model of the thrifty gene theory native american obesity is hypothesized to result from three potential causes 1 a genetic predisposition or the thrifty gene 2 a rational addiction to nutrients and 3 dietary adjustment costs these hypotheses are tested using a two stage household production approach and scanner data from a panel of native and non native supermarkets nutrient intake for both groups is strongly influenced by adjustment costs native americans tend to place higher implicit valuations on protein relative to fats and carbohydrates compared to non natives consequently reductions in real carbohydrate prices over time may be a cause of high incidence of native american obesity

in search of giffen behavior in search of giffen behavior i introduction the existence of giffen behavior has intrigued students of traditional consumer theory for many years stigler 1947 1948 and hicks 1956 dealt with the giffen good by dismissing it as a theoretical possibility but a practical impossibility this solution was met with some discord especially by boland 1977 according to boland if demand theory cannot be revised to dismiss the theoretical possibility of a giffen good it should at least be able to explain why giffen goods do not exist empirically dougan 1982 answered boland s critique by demonstrating the impossibility of observing a giffen good at the market level because the estimated demand curve is the locus of market equilibria derived from a shifting supply curve it must slope downward in the long run if walrasian stability conditions hold this suggests empirical evidence of a giffen good from market data is impossible to obtain however the possibility of giffen behavior at the individual level is not ruled out more recently silberberg and walker 1984 explored the consistency of giffen behavior using marshall s additive utility assumption they conclude that the giffen paradox is consistent with marshall s assumptions but deem its actual existence a pathological case dwyer and lindsay 1984 provide an interesting historical perspective of the often cited irish potato example of giffen behavior they point out that no known reference by robert giffen to the irish potato exists although the example abounds in principles and intermediate textbooks 1 furthermore they argue that the classic irish potato example of a giffen good did not actually occur since a supply reduction due to the famine would have caused the price of potatoes to decline if potatoes were a giffen good but no such decline was observed interestingly recent experimental work by battalio dwyer and kagel 1987 battalio kagel and kogut 1988 and silberberg warren boulton and asano 1987 provides some evidence for the existence of giffen behavior the battalio kagel and kogut study found that poor rats those whose incomes only allow below normal levels of fluid intake decrease the quantity demanded for quinine water in response to a lower price rats used the increased purchasing power to buy larger quantities of root beer in a controlled experiment involving monkeys silberberg warren boulton and asano found an increase in the price of bitter food pellets caused consumption of these pellets to increase battalio dwyer and kagel found other evidence of giffen behavior in the form of labor supply curves that were positively sloped at low wages but backward bending at higher rates common textbook examples of giffen behavior meat and potatoes beer and whiskey or alfred marshall s transportation problem employing typical indifference curve illustrations take place in a two commodity world with exogenous prices and a negative income effect strong enough to overcome the substitution effect these classical examples rely on utility function implying unusually shaped indifference maps by contrast this paper shows how giffen behavior can occur independent to a large degree of the form of the utility function the model offers an alternative explanation of giffen like behavior that is consistent with commonly cited examples and recent experimental work the results illustrate not only the possibility but the plausibility of giffen behavior ii the utility maximization problem begin by considering the typical example of a giffen good that of potatoes and meat the analysis is confined to peasants of very modest means assume the two goods meat m and potatoes or spuds s have exogenously determined prices given by p sub m and p sub s respectively the fixed income of consumers is denoted by r following the typical presentation of the giffen problem further assume peasant incomes are too small for subsistence on meat alone but are sufficient for subsistence solely on potatoes

an inverted u relationship between inequality and long run growth abstract the relationship between income distribution and long run economic growth has been a popular topic in recent economic research existing theoretical works find either a positive or a negative relationship but not both in this paper we propose an inverted u relationship between initial income distribution and long term economic growth and estimate and test the relationship using cross country data

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

is income inequality harmful for regional growth evidence from the european union this article examines the relationship between income inequality and economic growth in the regions of several european union countries over the period 1993 2002 using the information provided by the european community household panel taking into consideration the relevance of spatial effects in this context different versions of a spatial econometric model are estimated the results indicate that the degree of income dispersion is negatively associated with regional growth this finding is in fact robust to various alternative specifications including a number of additional explanatory variables such as initial per capita gdp the sectoral composition of economic activity human capital stock population density and market potential furthermore the observed negative correlation between income inequality and economic performance does not depend on the specific measure used to quantify the degree of income dispersion

disaggregating food consumption parameters designing targeted nutritional interventions abstract this article is concerned with a new nutritional intervention strategy which is based on the belief that malnourished people eat different types of food to the well nourished the calculation of disaggregated food consumption parameters can identify inferior food commodities and the subsidization of these commodities will target intervention to those most in need the effectiveness of this policy depends on the understanding of its theoretical basis the author introduces the policy maker to this by reviewing the theoretical basis for consumption analysis and then several key studies

a comparison of international income inequality an ordered probit model analysis in this study the ordered probit model with marginal effect was applied to examine the key elements that influence changes in the gini levels the empirical results indicated that export incentives and poverty have a positive impact on the gini levels moreover the marginal effect revealed that export incentives increase income inequality for countries with higher inequality and reduce inequality for those countries with a relatively even income distribution likewise the study found that the asian pacific economic cooperation apec and the eu countries move from inequality to equality more efficiently than countries in the latin american integration association laia

asymmetric intrahousehold allocation of calories in china to analyze intrahousehold calorie allocation we propose a new framework that takes into account asymmetric consumption behavior due to liquidity constraints and loss aversion we find that intrahousehold calorie allocation responds asymmetrically to expected declines and increases in household food availability in china compared with previous studies based on symmetric consumption behavior our framework provides stronger evidence of gender bias in intrahousehold calorie allocation among children in urban areas and among elderly people in rural areas and of demographic bias between girls and prime age adults in both urban and rural areas implications for demographic targeting in nutrition programs are discussed copyright 2010 oxford university press

income effects of donated commodities in rural panama analyses of food expenditure data from rural households in panama showed that the marginal propensity to consume food out of additional income in the form of donated food is not different than the marginal propensity to consume food out of money income for households participating in the veraguas supplemental feeding program these results suggest that take home food programs can have significant income mediated impacts on the acquisition of food and accordingly food supplementation programs should be designed to maximize the income value of the donated commodities in terms of prices prevailing in the local markets

refitting the kuznets curve using a gender specific threshold model abstractprevious studies have reached mixed conclusions regarding the relationship between inequality and per capita income these studies however fail to consider gender differences in income inequality and how these may impact on the relationship between income inequality and per capita income using australian taxation statistics we derive three sets of gini coefficients i e female male and total for the period 1950 2013 we then examine the relationship between inequality and real per capita income and find that a gender specific threshold panel regression outperforms three other conventional models our findings suggest that one set of coefficients does not fit all in that the use of aggregate and constant coefficients may mask variations within and between gender inequality over time

the political economy of growth a critical survey of the recent literature this article reviews the recent literature on the political economy of growth focusing on the research that has developed at the intersection of the endogenous growth literature and the new political economy it explores the relationship among four key variables economic growth and capital accumulation political instability political freedom and democratic institutions and income inequality

the theory and econometrics of health information in cross sectional nutrient demand analysis understanding the role of health information in food and nutrient demand has become an important issue over the last decade endogeneity and measurement error are two empirical problems that are inherent in this type of analysis while some type of instrumental variables estimation would appear the obvious solution this article provides several theoretical and empirical reasons why this is not the case in cross sectional analysis an alternative estimation strategy is pursued an empirical example is given and the implications are discussed copyright 2001 oxford university press

does education raise productivity or just reflect it education has an important effect on wages but it not clear whether this is because education raises productivity or because education is simply a signal of ability we implement a number of existing tests for discriminating between these two explanations and find that they do not support the signalling hypothesis however we have severe reservations about these results and we propose an alternative test based on changes in education incentives caused by changes in the minimum school leaving age in the 1970s using this idea we find that uk data appear to strongly support the human capital explanation an important issue in the economics of education is that an individual s education has an effect on wages paid in the labour market for example blundell et al 2003 uses detailed education and subsequent earnings information for a cohort of male individuals born in 1958 to estimate that the returns to a uk degree typically of 3 year duration relative to graduating from high school at 18 with 2 a level qualifications a necessary but not sufficient condition for admission to university is a 24 wage premium human capital explanations pioneered by becker 1962 and schultz 1963 suggest that the correlation between education and wages is due to education enhancing productivity however earnings may rise in response to education not because of any effect on productivity but simply because education may act as a signal of productivity employers believing that education is correlated with productivity will screen workers for their education and pay higher wages to the more educated the employers beliefs will be confirmed by their experience if it is the case that high productivity individuals signal this by choosing high levels of education it will be optimal for individuals to behave in this way if the cost of acquiring education is less for high productivity individuals than it is for low productivity individuals thus under reasonable conditions the market will be characterised by a separating equilibrium where higher productivity individuals choose higher levels of education than lower productivity workers and earn correspondingly higher wages the theory is largely due to spence 1973 1979 and the subsequent empirical literature was reviewed by groot and oosterbeek 1994 riley 2001 provides an excellent modern survey chevalier harmon and walker are fellows of iza in bonn and are affiliated with the institute for the study of social change issc in dublin this paper is part of the issc policy evaluation programme chevalier and walker are also affiliated with the centre for the economics of education at the london school of economics lse the support of all of these bodies for facilitating our collaboration is acknowledged harmon is grateful to university college london for their hospitality during his nuffield foundation new career development fellowship in the social sciences comments from steve machin and three anonymous referees greatly improved the exposition of this paper we are also grateful to richard blundell and to seminar participants at the lse and the tinbergen institute in amsterdam for their comments and to vincent o sullivan for excellent research assistance the usual disclaimer applies

market intervention policies for increasing the consumption of nutrients by low income households this study employs a market equilibrium displacement approach to examine the nutrient consumption effects of market intervention programs such as food subsidies income transfers and agricultural input subsidies the results permit comparison of the direct treasury costs of achieving marginal increases in nutrient intake with alternative programs when applied to a case study of the food markets and population of cali colombia it was found that a marginal increase in caloric intake among the poor could be achieved at lowest cost with a consumer subsidy of certain cereals although black market activity might raise this cost to that of an income subsidy

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

inequality is bad for growth of the poor but not for that of the rich the paper assesses the impact of overall inequality as well as inequality among the poor and among the rich on the growth rates along various percentiles of the income distribution the analysis uses micro census data from u s states covering the period from 1960 to 2010 the paper finds evidence that high levels of inequality reduce the income growth of the poor and if anything help the growth of the rich when inequality is deconstructed into bottom and top inequality the analysis finds that it is mostly top inequality that is holding back growth at the bottom

the demand for calories in developing countries this paper uses household survey data on consumption to analyze the determinants of calorie intakes in developing countries it relies on characteristic demand analysis for a demand function specification for calories it explores the effect of calories price differences income and other socioeconomic factors on the intracountry and intercountry distribution of calorie intakes the paper reaches three broad conclusions i both income and price elasticities of demand for calories are below unity and are substantial for poorer consumers ii even a moderate increase in calorie prices implies a large nutritional sacrifice for the poor if present income growth and distribution trends continue and iii if moderate redistribution policies permit a substantial portion of the income increase to be allocated to the poor sizable calorie price increases would not rule out elimination of malnutrition

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
