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

joint confidence intervals for income shares and lorenz curves in a recent paper beach and davidson 1983 extended the principles of statistical inference to lorenz curves and income shares by establishing the asymptotic distribution and covariance structure of a vector of lorenz curve ordinates corresponding to a set of quantile abscissae one can thus use the lorenz curve and income shares no longer just as descriptive devices for summarizing distribution information but now also as analytical tools for comparing alternative distributions and carrying out conventional statistical inference on them it would clearly be desirable however to extend and complement this work by providing a method for computing a set of joint confidence intervals about these income shares and for illustrating graphically a joint confidence band about a set of estimated lorenz curve ordinates the present paper provides a new and simple technique for doing this when analyzing differences between sets of income shares or lorenz curves one typically wants to elicit more detailed information than is provided by a standard joint chi square test on the overall set of shares that is when the hypothesis of two sets of shares being the same is rejected we generally want to know further which particular differences in shares are different from zero and of these nonzero differences which are positive and which negative savin 1980 a natural way of providing such information is through multiple comparison procedures developed in this paper in a recent work richmond 1982 has developed a general method of finding multiple comparison intervals that is particularly suited to the present problem and in this situation appears to dominate other conventional alternatives in contrast for example to scheff s s projection method richmond s approach focuses on a set of primary points of interest income shares among a more general set of points including the lorenz curve ordinates and optimizes the joint confidence interval lengths on this primary set of points since estimated lorenz curve ordinates are built up from underlying income shares these shares perhaps further supplemented are natural choices for the primary set the method however also provides a joint confidence band that geometrically bounds the set of lorenz curve ordinates and interpolated segments between them the present

making inferences about the polarization welfare and poverty of nations a study of 101 countries 1970 1995 stochastic dominance techniques are adapted and employed to study the extent and progress of polarization welfare and poverty of 101 nations over the period 1970 1995 the adaptations provide methods of comparing mass relocation by evaluating various degrees of right and left separation between distributions the results reveal that whilst welfare increased and then diminished and poverty diminished and then increased polarization between rich and poor countries continued unabated throughout the period emphasizing the distinction between polarization and inequality copyright 2004 john wiley sons ltd

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

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

the effect of safety net programs on food insecurity we investigate to what extent major safety net program benefits affect food insecurity in families we impute program eligibility and benefits in each state for 2001 2009 accounting for cross program eligibility rules we use simulated eligibility and benefits for a nationally representative sample as instruments for imputed eligibility and potential benefits among nonimmigrant low income single parent families 1 000 in potential cash or food benefits reduces the incidence of food insecurity by 1 1 percentage points on a base of 33 percent cash and food both reduce food insecurity the results highlight the importance of jointly considering a full range of safety net programs

international comparisons of welfare and poverty dominance orderings for ten countries inference based stochastic dominance procedures are applied to luxembourg income study data to rank ten western countries in terms of standards of living and poverty first order dominance comparisons ranks more than 50 percent of all pairwise comparisons and second order generalized lorenz dominance adds another 25 percent truncated dominance analysis is used to make inferences about poverty and up to 98 percent of the truncated distributions are ordered the results differ substantially from those obtained when only relative incomes and inequality are considered

inequality in male and female earnings the role of hours and wages the authors decompose annual earnings into hours of work and hourly earnings and analyze male female differences in earnings inequality using canadian data their results indicate that the larger female inequality in earnings is due to a greater inequality in the distribution of hours of work the distributions of wages for men and women are either statistically indistinguishable or more equal for women the authors compare two data points 1988 and 1981 and find the same structure in the gender comparisons also changes between 1988 and 1981 in earnings inequality are generated from movements in the hours distributions copyright 1996 by mit press

predicting the effects of in kind transfers on labor supply few empirical questions in economics have received the degree of attention that has been directed at measuring the impact of income transfers on work incentives the labor market effects of cash assistance have been carefully examined by numerous investigators while in kind programs have received relatively scant treatment despite that over the past twenty years the composition of federal antipoverty expenditures has dramatically shifted in favor of in kind aid two arguments are frequently offered in support of this change in approach to combatting poverty the first expresses concern over the competence of the poor to make wise decisions regarding their own consumption activity restricted transfers are a means of helping the poor while ensuring that the assistance is used in accordance with society s views on what will best improve the lot of recipients the second argument is that in kind transfers are less attractive to the poor than unrestricted cash grants and as such offer greater incentives for the poor to work and leave the welfare rolls this is a question for which little direct evidence exists given the absence of explicit studies to draw upon it has been natural to consider the disincentive effects of in kind transfer programs within conventional models by treating the transfers as if they had taken the form of cash this is a valid approach only if these programs induce the same consumption patterns as do money transfers existing evidence indicates that this is often not so a sizeable literature has evolved concerning recipient valuation of in kind assistance studies that entail computation of cash equivalent values for food stamps 6 7 18 20 22 24 public housing 7 8 15 and medicaid 20 24 provide evidence that these transfers are frequently valued well below market cost this indicates that many current and prospective recipients of in kind assistance are by the nature of the programs forced to consume a different mix of commodities and leisure than they would have had they received cash in terms of economic theory this means that the appropriate model should incorporate quantity constrained commodity demand and labor

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

comparing cash and voucher transfers in a humanitarian context evidence from the democratic republic of congo despite recent calls in support of cash transfers there is little rigorous evidence of the relative impacts of cash versus in kind transfers especially in humanitarian contexts where a majority of such programs take place this paper uses data from a randomized experiment in the democratic republic of congo to assess the relative impacts and costs of equivalently valued cash and voucher transfers the voucher program distorted households purchases along both the extensive and intensive margin as compared with unconstrained cash households yet there were no differences in food consumption or other measures of well being in part due to the fact that voucher households were able to resell part of what they purchased as there were no significant benefits to vouchers cash transfers were the more cost effective modality for both the implementing agency and program recipients in this context

wealth inequality theory measurement and decomposition this paper reviews the basic principles of inequality measurement underlining the advantages and shortcomings of alternative measures from a theoretical standpoint and in the context of the study of the distribution of wealth adopting the two most popular measures the gini index and the p shares the paper documents wealth inequality in canada using the 1999 2005 and 2012 survey of financial security sfs it carries out several decompositions with covariates featuring dfl type reweighting methods and gini and p shares rif regressions the latter parallel decompositions deepen our understanding of how changes in socio demographic characteristics including the compensating role of family formation and human capital impact wealth inequality

robust inference concerning recent trends in us environmental quality understanding trends in environmental quality is important for individuals and policymakers typically trends in environmental quality are determined solely through comparisons of unconditional or conditional mean pollution levels however reaching unambiguous conclusions on the basis of only the first moment of the unconditional or conditional distribution is problematic since it ignores what is occurring in different regions of the distribution even relying on indices that incorporate both mean and variance is suspect to the extent that relative rankings are not typically robust to index choice addressing these concerns we adapt recent developments in the stochastic dominance literature to test for unambiguous relations between current and past distributions of toxic releases using epa data from 1988 1999 we find statistically significant evidence that the unconditional 1999 distributions of air land underground and total toxic releases dominate in a first degree sense their respective 1988 distributions while some of this improvement is explained by economic growth pollution net of income improved over the sample period as well finally we document robust differences in the distribution of pollution across regions in the us copyright 2004 john wiley sons ltd

testing for the monotone likelihood ratio assumption although monotonicity of the likelihood ratio for conditioned densities is a common technical assumption in economic models empirical tests for its plausibility do not appear to have been conducted this article develops such a test based on the theory of order restricted inference that is robust with respect to the correlation structure of the distributions being compared the test is applied to study the technology revealed by agricultural production experiments for the data under scrutiny the results support the monotone likelihood ratio assumption in a second application we find some support for the assumption of affiliation among bids cast in a multiple round vickrey auction for a consumption good

the impact of food stamps on us poverty in the 1980s a marginal dominance analysis the relative effectiveness of the us food stamp program in reducing the incidence and depth of poverty is compared at a number of poverty lines across time the analysis is based upon an extension of dominance methods for ordering poverty recently developed statistical inference procedures and a merged data set that permnits an unusually comprehensive measure of income the comparative effectiveness of the food stamp program in reducing headcount poverty over time is contingent on the poverty line selected however the reduction in poverty gaps is greater in 1990 than in 1982 regardless of the poverty line chosen the sensitivity of the results to the income concept equivalence scale and time period used for measuring income are also considered

a stochastic dominance approach to the measurement of discrimination abstract this note suggests a bridge between stochastic dominance rothschild and stiglitz 1970 17 1973 18 inequality measurement atkinson 1970 1 and discrimination measurement gastwirth 1975 10 discrimination orderings are defined and illustrated through discrimination curves in the same spirit as stochastic dominance analysis the main result which links the second order discrimination curve and the gastwirth discrimination index also generalizes the equivalence between generalized lorenz dominance and second order stochastic dominance

quantitative easing and bank lending evidence from japan abstract prior to the recent global financial crisis one of the most prominent examples of unconventional monetary stimulus was japan s quantitative easing policy qep most analysts agree that the qep did not succeed in stimulating aggregate demand sufficiently to overcome persistent deflation however it remains unclear whether the qep simply provided little stimulus or whether its positive effects were overwhelmed by the contractionary forces in japan s post bubble economy in the spirit of kashyap and stein 2000 and hosono 2006 this paper uses bank level data from 2000 to 2009 to examine the effectiveness in promoting bank lending of a key element of the qep the bank of japan s injections of liquidity into the interbank market we identify a robust positive and statistically significant effect of bank liquidity positions on lending especially for weaker banks suggesting that the expansion of reserves associated with the qep boosted the flow of credit however the overall size of that boost was probably quite small first the estimated response of lending to liquidity positions in our regressions is small second although the boj s reserve injections boosted bank liquidity significantly much of the effect was offset as banks reduced their lending to each other finally the effect of liquidity on lending appears to have held only during the initial years of the qep when the banking system was at its weakest by 2005 even before the qep was abandoned the relationship between liquidity and lending had evaporated

changes in the distribution of wages in canada 1981 1992 this article uses microdata to study the changes in the distribution of weekly wages in canada from 1981 to 1992 changes in the distribution are analyzed using lorenz curves and eight different univariate measures of inequality evidence is presented that indicates that inequality is anticyclical increasing during recessions and falling during business cycle expansions moreover after changes in the cycle are accounted for there has been a clear upward trend in wage inequality comparisons between the canadian and the u s distributions show that wage inequality was less pronounced in canada than it was in the united states in the 1980s and was increasing in canada relative to the united states from 1989 to 1992

testing for marginal changes in income distributions with lorenz and concentration curves asymptotically distribution free statistical tests for comparing absolute and relative lorenz and concentration curves are provided the procedures do not require independent samples and can be used to test for marginal changes in income distributions the tests are illustrated using a large sample of tax returns that have been randomly selected for audit by the internal revenue service the tests reveal the marginal effects of systematic underreporting of income and tax liabilities on the u s income distribution copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

cash welfare as a consumption smoothing mechanism for divorced mothers abstract while there has been considerable research on the disincentive effects of cash welfare under the aid to families with dependent children afdc program there is little evidence on the benefits of the program for single mothers and their children one potential benefit of this program is that it provides short run consumption insurance for women at the point that they become single mothers this is only true however to the extent that the program is not crowding out other sources of support such as own savings labor supply or transfers from others i assess the importance of this insurance mechanism by measuring the extent to which afdc smooths the consumption of women who transition to single motherhood through marital dissolution i use longitudinal data on family structure and consumption expenditures on food and housing from the panel study of income dynamics psid matched to information on the welfare benefits available in each state and year over the 1968 1985 period i find that raising potential benefits by one dollar raises the food and housing consumption of women who get divorced and their families by 28 cents this estimate implies that for each dollar of afdc received by this population their consumption of these categories of goods rises by up to 51 cents this is roughly the share of food and housing in the consumption bundle of divorced mothers and their families suggesting little crowdout of other sources of support

ranking income distributions a large variety of policy questions involve choices between social states and a consequent ordering of the feasible alternatives when these social states are related to the levels of welfare experienced by individuals or households two central issues stand out in determining the relative desirability of different social outcomes one of these is the essentially positive exercise of achieving comparability between households with different characteristics such as composition or preferences operating in different environments for example facing different price structures the other concerns the normative judgments implicit in the evaluation of alternative allocations of resourcesthe emphasis placed on inequality between households and the extent to which greater inequality can be compensated by higher average living standards this paper focuses on the second of these issues and in doing so we abstract from the problem of household comparability by considering a population of n households identical in all respects except for their incomes the question of ordering social states then becomes one of ranking income distributions over a group of anonymous households or individuals borrowing the usual assumptions imposed on consumer preferences we may suppose that a social ordering of income distributions can be represented by a welfare function 2

do intra household effects generate the food stamp cash out puzzle previous empirical studies have noted the higher marginal propensity to consume food out of food stamps in the united states compared to that out of cash income analyzing data from u s food stamp program participants we find evidence that this discrepancy may be driven primarily by the behavior of multiple adult households single adult households show no evidence of any discrepancy thus our results suggest that food stamp and cash income welfare or market may have very different impact on the intra household allocation process and that this is reflected empirically in the cash out puzzle

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

the effects of benefit timing and income fungibility on food purchasing decisions among supplemental nutrition assistance program households the supplemental nutrition assistance program snap is the largest nutritional safety net in the united states prior research has found that participants have higher consumption shortly after receiving their benefits followed by lower consumption towards the end of the benefit month known as the snap benefit cycle this consumption pattern has been found to have negative effects on beneficiaries we hypothesize two behavioral responses of snap participants may work in tandem to drive much of the cycle 1 short run impatience a higher preference to consume today and 2 fungibility of income the degree of substitutability between a snap dollar and a cash dollar using data from the national food acquisition and purchase survey foodaps a newly developed nationally representative survey of daily food acquisitions by snap households we find evidence of both behavioral responses however the degree of short run impatience and fungibility of income is found to differ significantly across poverty levels and use of grocery lists to plan food purchases snap households could gain from food purchase planning education

international spillovers of policy uncertainty using the baker et al 2013 index of policy uncertainty for six developed countries this paper estimates spillovers of policy uncertainty we find that spillovers account for slightly more than one fourth of the dynamics of policy uncertainty in these countries with this share rising to one half during the financial crisis the us and uk are responsible for a large fraction of the spillovers since the financial crisis while the remaining countries are all net receivers of policy uncertainty shocks during and after this period

does money matter the effects of cash transfers on child development in rural ecuador abstract a large body of research indicates that child development is sensitive to early life environments so that poor children are at higher risk for poor cognitive and behavioral outcomes these developmental outcomes are important determinants of success in adulthood yet remarkably little is known about whether poverty alleviation programs improve children s developmental outcomes we examine how a government run cash transfer program for poor mothers in rural ecuador influenced the development of young children random assignment at the parish level is used to identify program effects our data include a set of measures of cognitive ability that are not typically included in experimental or quasi experimental studies of the impact of cash transfers on child well being as well as a set of physical health measures that may be related to developmental outcomes the cash transfer program had positive although modest effects on the physical cognitive and socioemotional development of the poorest c

forecasting the effects of a negative income tax program this paper outlines a scheme that forecasts the change in net earnings or in hours worked that results from the introduction of a negative income tax nit program the authors illustrate this scheme by estimating labor supply functions for married men married women and single women who participated in the seattle denver income maintenance experiments these functions are then used to simulate the effects of several nit programs the findings suggest that changes in the wage rate of an individual covered by an nit program result in important changes in the hours of work of the individual s spouse

on evaluating income distributions rank dominance the suppes sen grading principle of justice and pareto optimality rawls s study 1970 suggests the rank dominance condition for evaluating income distributions rank optimal non rank dominated income distributions are always pareto optimal however pareto optimality implies rank optimality if and only if a symmetry condition on the set of attainable income distributions dubbed equal opportunity holds rank dominance is equivalent to the suppes sen 1970 justice grading principle as applied to attainable income distributions the set of attainable income distributions is defined so as to recognize possible interdependence between total income and the distribution of income we also note that if total income is independent of the distribution of income as is the case in many equality of income studies then the equal opportunity condition is automatically satisfied hence the pareto and rank dominance criteria are equivalent

unconventional monetary policy and the credit channel in the euro area abstract we disentangle credit supply and demand and we then embed this information into a bayesian threshold var model to investigate the importance of the demand channel and the broad credit channel in the transmission of unconventional monetary policy on the macroeconomy during financial stress periods we find that during such periods ump shocks boost aggregate demand for loans increase agents net worth and revitalize credit to firms and households in addition counterfactual analysis suggests that non standard policy measures aiming at stimulating loan demand and relaxing banks balance sheet constraints would provide a significant support to economic activity prices and the financial sector

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

statistical inference of progressivity dominance an application to health care financing distributions this paper employs a distribution free statistical test suitable for comparisons based on dependent samples to analyse changes in health care financing distributions on finnish data in distinction to the more general summary index approach used in most studies of progressivity measurement the difference between the lorenz curve of income inequality and the concentration curves of various taxes and payments is used to evaluate progressivity dominance and changes in progressivity sample weights are applied to account for the effect of sampling design and non response the analysis demonstrates that the dominance approach can be successfully applied to various types of distributional problems besides comparisons concerning differences in income distributions as an empirical application the paper presents estimation results for the progressivity of various health care financing sources using data from the 1987 and 1996 finnish health care surveys

relative deprivation and economic welfare a statistical investigation with gini based welfare indices the average level of relative deprivation is considered as a measure of the economic welfare or standards of living for a society this approach yields welfare indices that are weighted combinations of the mean income and the gini coefficient there has been no systematic international comparison of these gini based welfare indices in this paper they are applied to compare relative deprivation and economic welfare using data from the luxembourg income study the asymptotic distributions of estimators of gini based welfare indices are provided under weighted sampling

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

relative undernutrition in puerto rico under alternative food assistance programmes in the early 1980s puerto rico experienced a conversion from the food stamp program fsp to the nutrition assistance program nap and a severe recession to compare relative undernutrition in puerto rico in 1977 and 1984 stochastic dominance methods and statistical inference procedures are applied to nutrient distributions to separate the effect of the recession from the effect of converting food coupons to cash benefits a multiple regression model of nutrient consumption is also estimated in the dominance comparisons every improvement in nutrition status between 1977 and 1984 is statistically significant at the lowest quintile while no case of worsening undernutrition is significant at the lowest quintile the multiple regression model provides some evidence that the conversion from food coupons to cash might have reduced nutrition status in the lowest quintile but a larger proportion of food assistance was allocated to low income households under the nap than under the fsp no evidence of signi

do snap participants expand non food spending when they receive more snap benefits evidence from the 2009 snap benefits increase this study examines the expenditure response to the largest increase in supplemental nutrition assistance program benefits instituted in april 2009 investigating the effects in both food and non food spending categories i find that the rise in snap benefits increased not only food at home expenditures but also housing transportation and education expenditures of snap households relative to those of non snap households specifically the snap benefit increase leads to the reduced out of pocket spending on food for infra marginal snap recipients and the freed up resources allowed households with bounded budgets to fund other essential needs such as paying mortgage rent utility fee transportation expenses as well as tuition examining non food expenditures provides a more complete picture of the impact of the snap benefit increase by shedding light on the spillover effect of the policy change the result also derives policy implication on ongoing debate about snap allotment generosity

innis lecture inference on income distributions this paper attempts to provide a synthetic view of varied techniques available for performing inference on income distributions two main approaches can be distinguished one in which the object of interest is some index of income inequality or poverty the other based on notions of stochastic dominance from the statistical point of view many techniques are common to both approaches although of course some are specific to one of them i assume throughout that inference about population quantities is to be based on a sample or samples and formally all randomness is due to that of the sampling process inference can be either asymptotic or bootstrap based in principle the bootstrap is an ideal tool since in this paper i ignore issues of complex sampling schemes and suppose that observations are iid however both bootstrap inference and to a considerably greater extent asymptotic inference can fall foul of difficulties associated with the heavy right hand tails observed with many income distributions i mention some recent attempts to circumvent these difficulties ce memoire tente de fournir une vue synthetique des diverses techniques disponibles pour faire des inferences a partir des repartitions de revenus on peut distinguer deux approches principales l une dans laquelle l objet vise est un indice d inegalite de revenus ou de pauvrete l autre est construite sur des notions de dominance stochastique d un point de vue statistique plusieurs techniques sont utilisees par les deux approches mais certaines techniques sont specifiques a l une ou a l autre approche l auteur postule que l inference a propos de quantites demographiques est fondee sur un echantillon ou des echantillons et que formellement tout le caractere aleatoire est attribuable au processus d echantillonnage l inference est soit asymptotique soit derivee par des technique de bootstrap en principe la seconde facon de proceder est un outil ideal puisque dans ce memoire l auteur ignore les problemes de procedures d echantillonnage complexes et presume que les observations sont idd cependant la seconde facon de proceder et encore plus la premiere peuvent rencontrer des difficultes associees au fait que l on observe des queues de distribution epaisses vers la droite dans plusieurs profils de repartition des revenus l auteur mentionne certains efforts recents pour contourner ces difficultes

enhancing nutrition a new tool for ex ante comparison of commodity based vouchers and food transfers summary this article presents a new analytical tool for ex ante comparison of the cost effectiveness of two transfer modalities in pursuing specific nutritional objectives it does so by introducing a metric to score the nutrient value of a food basket the nutrient value score nvs and explains how this metric can be combined with full supply chain analysis and costing to generate a new tool the omega value the use of the omega value allows policy makers who design a program with nutrition objectives to compare direct food transfers and commodity based food vouchers in terms of both cost efficiency and cost effectiveness 2013 elsevier ltd all rights reserved

lorenz dominance and welfare changes in the u s distribution of income 1967 1986 this paper examines income inequality in the untied states over the period 1967 86 using recently developed tests for differences in lorenz curves the authors are able to rank eighteen of nineteen annual comparisons in contrast standard techniques are able to rank only twelve these results suggest that the lorenz dominance principle is more empirically relevant than previously thought the tests reveal a sharp rise in u s inequality between 1978 and 1982 as well as a shift toward greater inequality over the entire period the authors also examine changes in economic welfare using the joint mean lorenz dominance principle copyright 1991 by mit press

the ecb and the interbank market this paper analyses the impact on the macroeconomy of the ecb s non standard monetary policy implemented in the aftermath of the collapse of lehman brothers in the fall of 2008 we study in particular the effect of the expansion of the intermediation of transactions across central bank balance sheets as dysfunctional financial markets seize up which we regard as a key channel of transmission for non standard monetary policy measures our approach is similar to lenza et al 2009 but we introduce the important innovation of distinguishing between private intermediation of interbank transactions in the money market and central bank intermediation of bank to bank transactions across the eurosystem balance sheet we do this by exploiting data drawn from the aggregate monetary and financial institutions mfi balance sheet which allows us to construct a new measure of the policy shock represented by the ecb s increasing role as a financial intermediary we find that bank loans to households and in particular to non financial corporations are higher than would have been the case without the ecb s intervention in turn the ecb s support has a significant impact on economic activity two and a half years after the failure of lehman brothers the level of industrial production is estimated to be 2 higher and the unemployment rate 0 6 percentage points lower than would have been the case in the absence of the ecb s non standard monetary policy measures

robust multidimensional poverty comparisons we demonstrate how to make poverty comparisons using multidimensional indicators of well being showing in particular how to check whether the comparisons are robust to aggregation procedures and to the choice of multidimensional poverty lines in contrast to earlier work our methodology applies equally well to what can be defined as union intersection or intermediate approaches to dealing with multidimensional indicators of well being to make this procedure of some practical usefulness the paper also derives the sampling distribution of various multidimensional poverty estimators including estimators of the critical poverty frontiers outside which multidimensional poverty comparisons can no longer be deemed ethically robust the results are illustrated using data from a number of developing countries

poverty in america 1970 1990 who did gain ground an application of stochastic dominance criteria employing simultaneous inequality tests in a partial panel atkinson 1987 proposed stochastic dominance criteria for analysing poverty which under certain conditions establish orderings of states for any poverty line and any poverty measure within given class refocusing debate on the nature of the income distribution of the poor employing new empirical techniques these criteria are implemented for the united states from 1970 to 1990 using the panel study of income dynamics results highlight the pivotal role of family size scale economies in consumption indicate different experiences for white versus non white groups and suggest that optimism over the progress of the poor is not warranted copyright 2003 john wiley sons ltd

how inefficient are multiple in kind transfers the inefficiencies from multiple in kind transfers are smaller than one would guess from studying such programs singly though medicaid can give rise to average discounts as large as 60 percent the benefits from the programs are quite large relative to recipients incomes effective marginal tax rates under in kind transfers are appreciably lower than they would be if the programs gave cash poverty rates among recipients are markedly lowered if one counts the value of in kind transfers as income this effect is insensitive to whether one accounts for the discounting of in kind transfers by recipients

cash equivalence welfare stigma and food stamps the food stamp program fsp is one of the largest domestic redistributive transfer programs with approximately 22 million participants at a cost of 12 billion in 1983 the stated objective of the fsp is to raise the levels of nutrition among low income households by providing such households with an opportunity to obtain a low cost nutritionally adequate diet 29 5 for program evaluation and cost forecasting accurate estimates of the determinants of eligible households program participation and food expenditure decisions are of particular concern in light of the elimination of the purchase requirement epr and other recent structural changes in the program the problem of obtaining these estimates has three dimensions first observations on the behavior of eligible households under the post epr institutional setting are required second the roles of welfare stigma and the cash equivalence of the in kind food stamps must be clarified finally because program participation is a household choice that affects food expenditures the interdependence of eligible households fsp participation and food expenditure decisions must be accommodated emphasizing an important component of this interdependence the connection between cash equivalence of stamps in the participation decision and in expenditures for food this paper tackles all three dimensions the purpose of this study is to determine the extent to which food stamps are cash equivalent and to determine which program and household characteristics including the degree of cash equivalence and stigma affect post epr food stamp program participation

the measurement and trend of housing inequality in the united states 1978 85 inequality in housing services for renters owners and all households in the united states is estimated for 1978 and 1985 hedonic techniques are applied to data from the american housing survey to derive values for housing services that include publicly provided as well as subsidized housing we find significant disparities in housing but substantially less inequality than in incomes in 1978 the top decile garnered 19 2 of housing services while the bottom decile received only 5 1 the trend however is towards greater equality in housing with large and statistically significant shifts across all deciles by 1985 the share of the top decile dropped to 16 3 a percentage decrease in share of 15 3 while that of the bottom decile rose to 5 7 a percentage increase of 11 4

a welfare economic analysis of labor market policies in the harris todaro model this paper presents a welfare economic analysis of the benefits of various labor market policies in the harris todaro labor market model the policies considered are a policy of modern sector job creation which i call modern sector enlargement msenl a policy of rural development which i call traditional sector enrichment tsenr and a policy of wage limitation in the urban economy which i call modern sector wage restraint mswr first i analyze the inequality effects of these policies i then perform two welfare economic analyses the first based on summary measures of labor market conditions total labor earnings unemployment inequality of labor incomes and poverty rates and the second based on dominance analysis in the labor market in both cases assuming that the costs are borne elsewhere the results of the welfare analyses are compared and it is shown that tsenr unambiguously increases welfare in the labor market using both approaches the other policies yield ambiguous results and no policy is unambiguously welfare decreasing

opening up pandora s box the effect of gender targeting and conditionality on household spending behavior in mexico s progresa program summary this paper evaluates the behavioral impact of conditionality and gender targeting on spending behavior in the progresa conditional cash transfer cct program from rural mexico results indicate that transfer income is not spent differently from general income suggesting that transfers exert only an income effect in addition women who have increased control over their extra cash are not significantly more likely to spend it in a family friendly way than they do household earned income both features entail significant costs to beneficiaries and program budgets our results indicate that further evidence is needed to confidently advocate for their inclusion in cash transfer ct programs

the monthly food stamp cycle shooping frequency and food intake decisions in an endogenous switching regression framework mean food spending by food stamp households peaks sharply in the first three days after benefits are received for those who conduct major grocery shopping trips only once per month 42 of all food stamp households mean food energy intake drops significantly by the fourth week of the month for the remaining households intake remains steady over the course of the month these patterns motivate an empirical model that simultaneously accounts for the shopping frequency and food intake decisions over time results have implications for policies that may affect the frequency of grocery shopping by food stamp households

nutrition and nonparticipation in the us food stamp programme microdata from the national food consumption survey are used to test for differences in caloric and protein intake distributions we compare poor households that participate in the us food stamp programme to eligible households that do not participate tests for stochastic dominance provide unambiguous evidence that eligible nonparticipants suffer from relative undernutrition compared to participating households probit analysis is used to identify characteristics of participating and nonparticipating households

public provision of private goods government may provide a good that can if legally permitted be supplemented by private purchases policy is determined by majority rule under standard assumptions on preferences a majority voting equilibrium exists a regime of positive government provision with no restriction on private supplements is shown to be majority preferred to a regime of either only market provision or only government provision combined public and private expenditure on the good is higher under this dual provision regime than under either of the alternatives under some preference configurations the median income voter is pivotal under others a voter with income below the median is pivotal

income redistribution going awry the reversal power of the concern for relative deprivation abstract we demonstrate that a rank preserving transfer from a richer individual to a poorer individual can exacerbate income inequality when inequality is measured by the gini coefficient this happens when individuals preferences depend negatively not only on work time effort but also on low relative income it is rigorously shown that the set of preference profiles that gives rise to this perverse effect of a transfer on inequality is a non empty open subset of all preference profiles a robust example illustrates this result

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

local governments in kind transfers and economic inequality abstract we examine how in kind transfers provided by local governments affect economic inequality the allocation of in kind transfers to households and the adjustment for differences in needs are derived from a model of local government spending behavior the model distinguishes between fixed and variable costs in production as well as mandatory programmatic spending components versus discretionary spending on different service sectors and target groups to estimate the model we combine norwegian data from municipal accounts and administrative registers for the period 1982 2013 we find that economic inequality is considerably lower when taking in kind transfers into account while the poor benefit from receiving a relatively large share of public services the equalizing effect of in kind transfers tends to be smaller than the equalizing contribution from public cash transfers when examining the time trends in inequality we find that local governments attenuated the growth in cash income inequality by re allocating in kind transfers to low income families this reduction in inequality is mostly due to changes in spending priorities across service sectors and target groups while the contribution from re allocation of resources across municipalities is much smaller

heterogeneous transmission mechanism monetary policy and financial fragility in the eurozone the eurozone economic activity and banking sector have shown substantial fragility over the last years with remarkable country heterogeneity using detailed data on lending conditions and standards we analyse along several key dimensions of heterogeneity how financial fragility has affected the transmission mechanism of the single eurozone monetary policy the analysis shows that the monetary transmission mechanism is time varying and influenced by the financial fragility of the sovereigns banks firms and households the impact of monetary policy on aggregate output is stronger during the financial crisis especially in countries facing increased sovereign financial distress this amplification mechanism moreover operates through the credit channel both the bank lending and the non financial borrower balance sheet channels our results suggest that the bank lending channel has been to a large extent neutralized by the ecb non standard monetary policy interventions but the policy framework until the end of 2011 was insufficient to overcome credit availability problems stemming from deteriorated firm net worth and risk conditions especially for small firms in countries under stress matteo ciccarelli angela maddaloni and jose luis peydro

inside the war on poverty the impact of food stamps on birth outcomes this paper evaluates the health impacts of a signature initiative of the war on poverty the introduction of the modern food stamp pro gram fsp using variation in the month fsp began operating in each u s county we find that pregnancies exposed to fsp three months prior to birth yielded deliveries with increased birth weight with the largest gains at the lowest birth weights we also find small but statistically insig nificant improvements in neonatal mortality we conclude that the sizable increase in income from fsp improved birth outcomes for both whites and african americans with larger impacts for african american mothers n this paper we evaluate the health consequences of a sizable improvement in the resources available to ameri ca s poorest in particular we examine the impact of the food stamp program fsp which in 2007 provided 34 billion in payments to about 13 million households on infant health our paper makes two distinct contributions first although the goal of the fsp is to increase the nutri tion of the poor few papers have examined its impact on health outcomes second building on work by hoynes and schanzenbach 2009 we argue that the fsp treatment represents an exogenous increase in income for the poor our analysis therefore represents a causal estimate of the impact of income on health an important topic with little convincing evidence due to concerns about endogeneity and reverse causality currie 2009 we use the natural experiment afforded by the nation wide rollout of the modern fsp during the 1960s and early 1970s our identification strategy uses the sharp timing of the county by county rollout of the fsp which was initially constrained by congressional funding authorizations and ultimately became available in all counties by 1975 speci fically we use information on the month the fsp began operating in each of the roughly 3 100 u s counties and examine the impact of the fsp rollout on mean birth weight low birth weight gestation and neonatal mortality throughout the history of the fsp the program para meters have been set by the u s department of agriculture usda and are uniform across states in the absence of the state level variation often leveraged by economists to eval uate transfer programs previous fsp research has typically resorted to strong assumptions as to the comparability of fsp participants and eligible nonparticipants currie 2003 not surprisingly the literature is far from settled as to what casual impact if any the fsp has on nutrition and health hoynes and schanzenbach 2009 use this county rollout to examine the impact of the fsp on food consumption using the psid they found that the introduction of the fsp increased total food spending and decreased out of pocket food spending importantly consistent with the predictions of canonical microeconomic theory the magnitude of the increase in food expenditures was similar to an equivalent sized income transfer implying that most recipient house holds were inframarginal that is they would spend more on the subsidized good than the face value of the in kind transfer as one of the largest antipoverty programs in the united states comparable in cost to the earned income tax credit eitc and substantially larger than temporary assistance to needy families tanf understanding fsp effects is valuable both in its own right and for what it reveals about the relationship between income and health 1

convergence of the south and non south income distributions 1969 1979 income distribution and inequalities in the southern united states are analyzed and compared with data for the rest of the country the evidence presented in this paper reveals that in the 1970s the souths income distribution either converged or moved significantly closer to the income distribution of the rest of the country the degree of convergence depends on the definition of the recipient unit and to a degree on the particular cost of living index used to deflate southern and non southern incomes the convergence is attributed in part to the labor unionization in the northeast and the resulting relocation of companies to the south data are from the 1970 and 1980 censuses and concern total household income excerpt

aggregate poverty measures the way poverty is measured is important for an understanding of what has happened to poverty as well as for anti poverty policy evaluation sen s 1976 pathfinding work has motivated many researchers to focus on the way poverty should be measured a poverty measure argued by sen should satisfy certain properties or axioms and the desirability of a poverty measure should be evaluated by these axioms during the last two decades many researchers have adopted the axiomatic approach pioneered by sen to propose additional axioms and develop alternative poverty measures the objective of this survey is to provide a clarification on the extensive literature of aggregate poverty measures in this survey we first examine the desirability of each axiom the properties of each poverty measure and the interrelationships among axioms the desirability of an axiom cannot be evaluated in isolation and some combination of axioms may make it impossible to devise a satisfactory poverty measure some axioms can be implied by other axioms combined and so are not independent some others are ad hoc and are disqualified as axioms for poverty measurement based on the interactions among axioms we identify the core axioms which together have a strong implication on the functional form of a poverty measure we then review poverty measures that have appeared in the literature evaluating the interrelationships among different measures and examining the properties of each measure the axioms each measure satisfies violates are also summarized in a tabular form several good poverty measures which have not been documented by previous surveys are also included

on the measurement of poverty official statistics in the united states and the united kingdom show a rise in poverty between the 1970 s and the 1980 s but scepticism has been expressed with regard to these findings in particular the methods employed in the measurement of poverty have been the subject of criticism this paper re examines three basic issues in measuring poverty the choice of the poverty line the index of poverty and the relation between poverty and inequality one general theme running through the paper is that there is a diversity of judgments which enter the measurement of poverty and that it is necessary to recognize these explicitly in the procedures adopted there is likely to be disagreement about the choice of poverty line affecting both its level and its structure in this situation we may only be able to make comparisons and not to measure differences and the comparisons may lead only to a partial rather than a complete ordering the first section of the paper discusses the stochastic dominance conditions which allow such comparisons illustrating their application by reference to data for the united states the choice of poverty measure has been the subject of an extensive literature and a variety of measures have been proposed in the second section of the paper a different approach is suggested considering a class of measures satisfying certain general properties and seeking conditions under which all members of the class which includes many of those proposed give the same ranking those sceptical about measures of poverty often assert that poverty and inequality are being confounded the third section of the paper distinguishes four different viewpoints and relates them to theories of justice and views of social welfare

statistical tests of changes in u s poverty 1975 to 1990 since president lyndon johnson declared the war on poverty three decades ago scholars have devoted many volumes to analyzing characteristics of poverty evaluating effectiveness of antipoverty policies and measuring changes in poverty unfortunately most poverty studies have focused primarily on the incidence of poverty rather than on both the incidence of poverty and the income distribution within the poor population although a k sen s 23 seminal work on measurement of poverty demonstrated the importance of constructing and using a distribution sensitive poverty measure in evaluating poverty the u s federal government still uses the proportion of poor as virtually the only indicator of poverty with few exceptions such as bishop formby and smith 5 most recent scholarly works on poverty issues including sawhill 21 hanratty and blank 17 and slesnick 24 are also concerned exclusively with the incidence of poverty and use a single poverty line in this study we demonstrate that a more comprehensive look at poverty using distribution sensitive measures and multiple poverty lines yields a different picture of poverty changes over time compared to what official u s statistics portray practically the comparison of poverty changes can be decomposed into three parts 1 setting a poverty line an income threshold below which a person is defined as poor this step is also called the identification of the poor and is very important in poverty study 2 choosing a method to aggregate individual poverty into overall poverty different methods of aggregating may lead to different conclusions about poverty changes therefore an appropriate method is essential for poverty study and 3 statistical inference since conclusions about poverty changes are drawn from a random sample of the population it is important to know whether the estimated poverty

international comparisons of income inequality tests for lorenz dominance across nine countries this paper examines income inequality across nine countries using the luxembourg income study data set new statistical tests and comparability of data provide an exceptionally clear picture of relative income inequality only 4 comparisons out of a possible 108 cannot be ranked in most cases differences in the definition of the recipient unit make little difference in the rankings irrespective of recipient units sweden norway and germany come out at the top of the ordinal lorenz ranking with australia canada and the united kingdom in the middle and the united states and switzerland at the bottom copyright 1991 by the london school of economics and political science

the international transmission of volatility shocks an empirical analysis this paper proposes an empirical model which can be used to estimate the international transmission of volatility shocks using this model we estimate that a one standard deviation increase in the volatility of the shock to us real gdp leads to a decline in uk gdp of 1 relative to trend and a 0 7 increase in uk cpi relative to trend at the two year horizon using a nonlinear open economy dsge model we find that these empirical estimates are consistent with the response to a perturbation to the volatility of foreign supply type shocks while an increase in the volatility of demand shocks has a negligible impact

truncation bias and the ordinal evaiuation of income inequality lorenz dominance analysis is used to examine the effect of top coding on the ordinal evaluation of u s income inequality across time current population survey microdata are adjusted for truncation bias and statistical inference procedures are used to examine biennial changes in unadjusted and adjusted lorenz curves beginning in 1985 the truncation bias has a significant effect on ordinal rankings of income inequality

the effect of the food stamp program on the nutrient intake of the eligible elderly an objective of the food stamp program recognized in its originating legislation is to increase the nutrient intake of the poor economic theory suggests this might be achieved through income effects and program related effects this paper using data from the food stamp cashout project tests the effectiveness of food stamps and direct cash transfers in achieving this goal for a sample of elderly households food stamp program effects were negligible and nutrient intake did not increase with income in either program controlling for the endogeneity of participation with a selection bias technique did not affect these results

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

consumption dominance curves testing for the impact of indirect tax reforms on poverty abstract a new tool is presented to test for the robustness of the impact on poverty of marginal tax reforms for pairs of commodities consumption dominance curves exist for every order of stochastic dominance an illustration is provided with bolivian data

assessing the economy wide effects of quantitative easing this article examines the macroeconomic impact of the first round of quantitative easing qe by the bank of england we attempt to quantify the effects of these purchases by focusing on the impact of lower long term interest rates on the wider economy we use three different models to estimate the impact of qe on output and inflation a large bayesian vector autoregression var a change point structural var and a time varying parameter var our estimates suggest that qe may have had a peak effect on the level of real gdp of around and a peak effect on annual cpi inflation of about points
