defining chronic poverty comparing different approaches in this study we discuss two methods commonly used in the literature to measure chronic poverty the permanent income approach where the chronically poor are those whose mean income over time is below the poverty line and the spells approach where the chronically poor are those households who are below the poverty line half of the time or more we check the differences between these two methods considering also several household characteristics the index we use is that of foster greer and thorbecke fgt with and when each method identifies the chronically poor which could be different individuals by each method and shows the percentage of the chronically poor while when the methods also take into account the depth of poverty our main goal is to show the differences between the two methods so that policymakers would have different perspectives on the problem of chronic poverty and could make decisions on this basis the results show that in the data used the permanent method and the spells

group lending repayment incentives and social collateral abstract in this paper we investigate the impact on repayment rates of lending to groups which are made jointly liable for repayment this type of scheme especially in the guise of the grameen bank in bangladesh has received increasing attention we set up and analyze the repayment game which group lending gives rise to our analysis suggests that such schemes have both positive and negative effects on repayment rates the positive effect is that successful group members may have an incentive to repay the loans of group members whose projects have yielded insufficient return to make repayment worthwhile the negative effect arises when the whole group defaults even when some members would have repaid under individual lending we also show how group lending may harness social collateral which serves to mitigate its negative effect

credit market constraints consumption smoothing and the accumulation of durable production assets in low income countries investments in bullocks in india in this paper we formulate and estimate a finite horizon structural dynamic model of agricultural investment behavior that incorporates the major features of low income agricultural environments income uncertainty constraints on borrowing and rental markets and the use of investment assets to generate income and smooth consumption the model is fit to longitudinal indian household data on farm profits bullock stocks and pump sets the estimated structural parameters are used to assess the effects on the life cycle accumulation of bullocks agricultural profits and welfare associated with complete markets and bullock liquidity and with second best policies that provide assured sources of income to farmers and weather insurance

measuring lifetime poverty abstract this paper presents an axiomatic framework for measuring lifetime poverty over multiple periods for an individual we argue that lifetime poverty is influenced by both the snapshot poverty of each period and the poverty level of the permanent lifetime consumption it is also influenced by how poverty spells are distributed over the lifetime we axiomatically characterize classes of lifetime poverty indices and derive dominance conditions of poverty orderings for both individual and societal lifetime poverty measurements

consumption vulnerability to risk in rural pakistan abstract as one of the dimensions of vulnerability this paper empirically investigates the inability of rural dwellers to cope with negative income shocks a variable coefficient regression model is applied to a two period household panel dataset collected in the north west frontier province pakistan an area with high incidence of income poverty and low human development the empirical model allows for a different ability to smooth consumption approximated by a linear function of households attributes and controls for the endogeneity of observed changes in income using qualitative information on subjective risk assessment estimation results show that the ability to cope with negative income shocks is lower for households that are aged landless and do not receive remittances regularly

intragenerational income mobility in latin america economic mobility has not been widely studied in developing countries until very recently owing to the lack of suitable data studying mobility requires longitudinal data tracking economic units that is individuals households or firms over time collecting this type of data is expensive and historically few latin american countries carried it out now however such data sets are available for a number of latin american and caribbean countries table a 1 in the appendix provides a list of available panel data sets that can be used for income mobility studies for these countries in this paper we discuss how the knowledge gleaned from mobility studies differs from comparable cross sectional analysis the structure of the paper is as follows the next section discusses what mobility is how it can be measured and how it differs from inequality the subsequent section reviews previous mobility studies in latin american countries the paper then summarizes the contributions of our own recent work and the final section discusses what lies ahead in mobility research for latin american economies

the effects of unions on investment and innovation evidence from wirs the above is representative of much popular discussion of the effects of unions on investment and innovation in the professional literature the view that unions deter investment by expropriating quasi rents is also commonplace see e g simons i944 baldwin i983 grout i984 in addition it is argued that union foisted restrictive work practices might make investment a more costly process see e g denny and nickell i989 in recent years the above theoretical notions have appeared to receive some empirical support in that in the united states the level of the investment capital ratio does appear to be lower in union firms see hirsch i988 and references therein in this paper we use information contained in the i 984 workplace industrial relations survey in order to investigate the actual impact of unions on investment the rest of the paper is organised as follows in section i i we informally review the alternative channels through which unions might affect investment section i 2 contains a simple theoretical model of investment which embodies all the alternative channels our results are to be found in section ii and finally some conclusions are contained in section iii

working wives and expenditure on services the major focus of this research is the relationship between a wife s employment and expenditure on time saving services multiple regression analysis of data from the 1972 1973 consumer expenditure survey indicates that two measures of the extent of a wife s participation in the labor force were influential in determining monetary outlay on services that are expected to be sensitive to the value of time other factors such as family income education and stage of the family life cycle also exert an impact on expenditure findings indicate that family expenditure on services is a complex process influenced by many factors besides a wife s employment

does industrialization build or destroy social networks abstract this article estimates the relationship between changes in industrialization and changes in social networks measures in indonesia during 1985 97 using repeated cross sections of nationally representative surveys we analyze a rich set of social interaction measures including various measures of voluntary associational activity levels of trust and informal cooperation districts that experienced rapid industrialization showed significant increases in most measures of social interaction however districts that neighbor rapidly industrializing areas exhibited high rates of out migration significantly fewer community credit cooperatives and a reduction in mutual cooperation as assessed by village elders manufacturing growth can be thought of as a proxy for income growth here the findings are contrary to several recent claims regarding the role of social capital in economic development

poverty persistence and transitions in uganda a combined qualitative and quantitative analysis despite uganda s impressive reduction in income poverty during the 1990s recent evidence has shown there to be substantial mobility into and out of poverty this paper represents one of the first attempts to combine qualitative and quantitative information to understand the factors and processes underlying poverty transitions and persistence in some instances similar factors are identified by both qualitative and quantitative approaches including lack of key physical assets high dependency ratios and increased household size in other instances though one approach identifies additional factors not so easily identified by the other for example the impacts of excessive alcohol consumption in many cases the paper argues that there is considerable value added in combining the two approaches allowing us to provide a much richer understanding of many of the processes underlying poverty and poverty transitions

do unions reduce investment evidence from canada the authors test for a link between unionization and net investment rates in canadian manufacturing analysis of data on 18 industries for the years 1967 87 reveals a negative non linear relationship the presence of unions appears to have reduced investment when the percentage of firms in the industry that were unionized was between 0 and approximately 50 with a plateau or slight positive marginal effect above this level in an industry moving from no unions to the mean level of unionization net investment and gross investment are predicted to fall by 66 74 and 18 25 respectively

changes in the u s wage structure 1963 1987 application of quantile regression the 1980 s witnessed rapid changes in the structure of wages in the united states in this study recently developed techniques for quantile regression are applied to every march current population survey since 1964 and changes in the return to schooling and experience at different points of the wage distribution are examined the quantile regression technique parsimoniously describes the entire conditional wage distribution this conditional distribution is used to examine changes in within group wage inequality as measured by the difference between conditional quantiles two linear models are considered a simple one group model and a 16 group model the results suggest that the returns to schooling and experience differ across quantiles of the wage distribution but their patterns of change are similar significant differences in wage inequality are also found across the various skill groups the paper also presents a new imputation method for cps data

unionization and profitability evidence of spillover effects ruback and zimmerman s 1984 event study which showed that formal union organizing activity significantly lowers a firm s market value provides compelling evidence that unionization reduces a firm s profitability union organizing activity may also have sizable cross firm or spillover effects on the performance of neighboring firms thus the total impact of union organizing on the wealth of firm owners may be substantially understated by focusing only on the firm in which the union organizing activity occurs this paper presents an alternative approach for estimating union spillover effects on profitability using a data set and methodology similar to ruback and zimmerman s we find that the total negative effects of unionization on profits after cross firm or spillover effects are included are nearly three times as large as the own firm effects reported by ruback and zimmerman the hypothesis that changes in unionization have spillover effects on nonunion firms is well known formal union organizing activity at one firm may increase the threat of unionization at other firms neighboring firms may respond to the greater threat of unionization

how economic contractions and expansions affect expenditure patterns in this study we attempt to understand how household budget allocations across various expenditure categories change when the economy is in recession or expansion the common assumption is that a household s tastes would not change as a function of economic conditions and therefore any adjustments in expenditure patterns during economic contractions expansions would simply be due to changes in the consumption budget standard economic models translate these budgetary effects into lateral movements along a set of fixed engel curves which relate category expenditure shares to total expenditures we propose and test a conceptual framework based on the notion of relative consumption which prescribes that for any given total consumption budget expenditure shares for positional goods services will decrease during a recession while shares for nonpositional goods services will increase i e shifting the entire engel curve upward or downward depending on the nature of the expenditure category and the economic conditions

credit as insurance in agrarian economies abstract this paper examines consumption credit as an insurance mechanism in agrarian economies it explains the more rapid adoption of new technology in the green revolution by large farmers who had greater access to consumption credit the paper also demonstrates how the emergence and expansion of consumption credit markets by mitigating the need for hoarding in order to meet consumption contingencies enhances growth by encouraging investment

is economic growth increasing disparities a multidimensional analysis of poverty in the lao pdr between 2003 and 2013 abstractthe asian story of miraculous growth and poverty reduction has reinforced mainstream views of development that equate high and sustained economic growth with progress in human wellbeing but understanding development only in terms of economic growth is not sufficient this paper offers a different perspective on possible effects of laos s transition from a subsistence oriented economy to a market oriented economy we used a multidimensional poverty approach with panel data for the years between 2003 and 2013 findings suggest that benefits were not equally distributed 50 per cent of people moved in and out of poverty and the other half was either non poor 37 or always poor 13

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

on measuring the benefits of lower transport costs despite large amounts invested in rural roads in developing countries little is known about their benefits this paper derives an expression for the willingness to pay for a reduction in transport costs from the canonical agricultural household model and uses it to estimate the benefits of a hypothetical road project estimation is based on novel cross sectional data collected in a small region of madagascar with enormous yet plausibly exogenous variation in transport cost a road that essentially eliminated transport costs in the study area would boost the incomes of the remotest households those facing transport costs of about usd 75 ton by nearly half mostly by raising non farm earnings this benefit estimate is contrasted to one based on a hedonic approach

real income equivalence among one earner and two earner families in an earlier paper we proposed a technique for making income comparisons across various household sizes in this paper we employ a modified version of that method to convert nominal income to some real equivalent comparable across families of a given size but with one or two family earners we begin with a discussion of some of the conceptual difficulties involved in making cross family size or structure comparisons in income we then describe spending pattern differences between one and two earner families the final section discusses our effort to convert nominal income into comparable real income units we conclude that nominal income differences between two and one earner families far overstate differences in standards of living excerpt

assessing the extent and nature of chronic poverty in low income countries issues and evidence discussions of chronic poverty have mostly considered its monetary dimensions with current evidence suggesting that such poverty is much more transient than chronic but chronic poverty is a real and important phenomenon potentially more important quantitatively than it first appears once account is taken of different methodological approaches and inevitable measurement difficulties the chronic poor have distinctive characteristics such as lack of assets or high dependency rates which may account for their persistent poverty the paper argues that it is also necessary to develop concepts of chronic poverty further covering relevant nonmonetary dimensions and not just relying on panel data

growth and chronic poverty evidence from rural communities in ethiopia abstract what keeps some people persistently poor even in the context of relative high growth in this article we explore this question using a 15 year longitudinal data set from ethiopia we compare the findings of an empirical growth model with those derived from a model of the determinants of chronic poverty we ask whether the chronically poor are simply not benefiting in the same way from the same factors that allowed others to escape poverty or whether there are latent factors that leave them behind we find that this chronic poverty is associated with several initial characteristics lack of physical assets education and remoteness in terms of distance to towns or poor roads the chronically poor appear to benefit from some of the drivers of growth such as better roads or extension services in much the same way that the non chronically poor benefit however they appear to have lower growth in this period related to time invariant characteristics and this suggests that they face a conside

trade unions investment and employment the implications of long term wage contracts and investment in capital on non cooperative wage bargaining between a firm and a union are analysed the union maximises a utilitarian utility function and the firm faces a neoclassical investment problem with internal adjustment costs the monopoly union outcomes with binding contracts is time inconsistent because the union has an incentive to renege on announced low wage strategies once the capital stock has been accumulated the monopoly union outcome without binding contracts leads to credible strategies which correspond to higher wages and lower levels of employment investment and the capital stock efficient contracts give rise to higher employment than monopoly union outcomes whether with or without long term wage contracts the results are illustrated with a numerical example finally when the game between the union and firm is repeated reputational equilibira provide a solution to the problem of time inconsistency

data gaps data incomparability and data imputation a review of poverty measurement methods for data scarce environments this paper reviews methods that have been employed to estimate poverty in contexts where household consumption data are unavailable or missing these contexts range from completely missing and partially missing consumption data in cross sectional household surveys to missing panel household data the paper focuses on methods that aim to compare trends and dynamic patterns of poverty outcomes over time it presents the various methods under a common framework with pedagogical discussion on the intuition empirical illustrations are provided using several rounds of household survey data from vietnam furthermore the paper provides a practical guide with detailed instructions on computer programs that can be used to implement the reviewed techniques

rent sharing holdup and wages evidence from matched panel data rent sharing by workers can reduce the incentives for investment if some of the returns to sunk capital are captured in higher wages we propose a simple measure of this holdup effect based on the size of the wage offset for firm specific capital accumulation using social security earnings records for workers in the veneto region of italy linked to detailed financial data for their employers we find strong evidence of rent sharing with an elasticity of wages with respect to potential rents per worker of around 4 arising mainly at larger firms with higher price cost margins on the other hand we find little evidence that bargaining lowers the return on investment instead firm level bargaining appears to split the rents after deducting the full cost of capital

converting asset holdings into livelihood an empirical study on the role of household agency in south africa summary this paper analyzes the complexities of converting assets into livelihood and the role that agency constraints play drawing inspiration from the capabilities approach and using household data from south africa linkages between assets and agency are identified by decomposing asset endowments impact on future livelihood by employing a method of path analysis akin to early heritability of traits studies theoretical asset based studies of chronic poverty are bridged with capabilities literatures the interaction between assets and agency is shown to be as important as asset to asset complementarities the results have wide ranging policy implications

transient poverty poverty dynamics and vulnerability to poverty an empirical analysis using a balanced panel from rural china china s economic reforms starting in the late 1970s have resulted in rapid economic growth with annual growth in gross domestic product averaging greater than 10 percent per year for more than thirty years accompanying this rapid growth in national accounts have been rapid and widespread reductions in poverty with these reductions in poverty however there has often been observed an increase in income inequality both between as well as within rural and urban sectors this rising income gap challenges the notion that economic reforms in china have been as successful as the poverty statistics would suggest in this paper we suggest that an alternative view would be to consider the effects of these reforms on changing the chronic nature of poverty and reducing household vulnerability to poverty using a balanced panel from rural china from 1991 through 2006 we find that most poverty among our sample has shifted from being chronic in nature to being transient with households either shifting into a state of being non poor moving in and out of poverty among our sample vulnerability to poverty has been declining over time but the declines are not uniform over time or space we decompose household vulnerability status into two proximate causes low expected income and high income variability finding vulnerability increasingly due to income variability additionally we demonstrate that vulnerable households have very different characteristics than non vulnerable households

chronic and transitory poverty evidence from egypt 1997 99 abstract this paper uses a panel data of 347 households in egypt to measure changes in household consumption during 1997 99 and to identify causes behind the changes per capita consumption has decreased for the households during this time the decrease has not been dramatic but it has occurred at all points along the distribution over the two year period the number of households who have fallen into poverty is over twice as large as the number of households who have climbed out of poverty about two thirds of overall poverty is chronic average consumption over time is below the poverty line and almost half of all poor are always poor we use quantile regression methods to identify the factors that explain total chronic and transitory poverty while our analysis is able to document the extent of transitory poverty it performs relatively poorly in explaining the determinants of this type of poverty the predominantly chronic nature of poverty in our sample and our ability to identify associated characteristics strengthens the case for targeting antipoverty interventions such as food subsidies

irrigation agricultural performance and poverty reduction in china the overall goal of our paper is to understand the impact that irrigation in china has had on grain production and incomes in general and income and poverty alleviation in poor areas in particular the paper seeks to meet three objectives first we describe the relationship among irrigation status yields and household crop revenue second we seek to understand the magnitude and nature of the effect that irrigation has on yields and crop revenue finally we seek to understand the impact that irrigation has on incomes in poor areas our analysis shows that irrigation contributes to increases in yields for almost all crops and in income for farmers in all areas the importance of crop income in poor areas and the strong relationship between crop revenue and irrigation provides evidence of the importance of irrigation in past and future poverty alleviation in china we also show that in the majority of the villages that invested in new irrigation returns are positive even after accounting for increases in capital and production costs 2005 elsevier ltd all rights reserved

social capital and contributions in a public goods experiment recent empirical studies from across the social and behavioral sciences find that social capital is associated with various measures of well being including economic growth stephen knack and phillip keefer 1997 and mortality ichiro kawachi bruce p kennedy and kimberly lochner 1997 these findings have inspired subsequent studies by economists examining the determinants of individual level measures of social capital e g alberto alesina and elianna la ferrara 2002 however experimental evidence from trust games conducted by edward l glaeser david i laibson jose a scheinkman and christine l soutter 2001 calls into question the efficacy of the most prevalent measures of social capital employed in the literature in contrast we show that these same measures are significantly associated with contributions in a public goods experiment and perform as well as the alternative measures of social trust suggested by glaeser et al because social capital is thought to influence wellbeing through its effect on public good provision our results bolster previous empirical work on the causes and consequences of social capital this abstract was borrowed from another version of this item

wealth weather risk and the composition and profitability of agricultural investments despite the growing evidence that farmers in low income environments are risk averse there has been little empirical evidence on the importance of risk in shaping the actual allocation of production resources among farmers differentiated by wealth the authors use panel data on investments in rural india to examine how the composition of productive and nonproductive asset holdings varies across farmers with different levels of total wealth and across farmers facing different degrees of weather risk income variability is a prominent feature of the experience of rural agents in low income countries the authors report evidence based on measures of rainfall variability that the agricultural investment portfolio behavior of farmers in such settings reflects risk aversion due evidently to limitations on consumption soothing mechanisms such as crop insurance or credit markets the authors results suggest that uninsured weather risk is a significant cause of lower efficiency and lower average incomes a one standard deviation decrease in weather risk measured by the standard deviation of the timing of the rainy season would raise average profits by up to 35 percent among farmers in the lowest wealth quartile moreover rainfall variability induces a more unequal distribution of average incomes for a given distribution of wealth wealthier farmers are willing to absorb significant risk without giving up profits to reduce production risk smaller farmers have to invest their limited wealth in ways that reduce their exposure to risk at the cost of lower profit rates the authors found that at high levels of rainfall variability differences in rates of profit per unit of agricultural assets were similar across classes of wealth but over the sample range of rainfall variability these rates of profit were always higher for the poorer farmers than for the wealthier ones suggesting that the disadvantages of small farmers in risk diffusion are more than offset by their labor cost advantage

estimation of price cost margins and union bargaining power for belgian manufacturing abstract this paper extends hall s 1988 hall r e 1988 the relationship between price and marginal cost in us industry journal of political economy 96 921 947 methodology to analyze imperfections in both the product and the labor market for firms in the belgian manufacturing industry over the period 1988 1995 we investigate the heterogeneity in price cost mark up and workers bargaining power parameters among 18 sectors within the manufacturing industry as well as the relationship between both parameters using a sample of more than 7000 firms our gmm results indicate that ignoring imperfection in the labor market leads to an underestimation of the price cost margin evaluated at perfect competition in the labor market these findings are confirmed in the sectoral analysis sectors with higher workers bargaining power typically show higher price cost margins

the distribution of income shocks during crises an application of quantile analysis to mexico 1992 95 moving beyond the simple comparisons of averages typical of most analyses of household income shocks this article employs quantile analysis to generate a complete distribution of such shocks by type of household during the 1995 crisis in mexico it compares the distributions across normal and crisis periods to see whether observed differences were due to the crisis or are intrinsic to the household types alternatively it asks whether the distribution of shocks during normal periods was a reasonable predictor of vulnerability to income shocks during crises it finds large differences in the distribution of shocks by household types both before and during the crisis but little change in their relative positions during the crisis the impact appears to have been spread fairly evenly households headed by people with less education poor single mothers or people working in the informal sector do not appear to experience disproportionate income drops either in normal times or during crises

growth inequality and poverty looking beyond averages the evidence is compelling that the poor in developing countries do typically share in the gains from rising aggregate affluence and in the losses from aggregate contraction but how much do poor people share in growth do they gain more in some settings than others do some gain while others lose does pro poor growth mean more or less aggregate growth recent theories and evidence suggest some answers but deeper microeconomic empirical work is needed on growth and distributed change only then will we have a firm basis for identifying the specific policies and programs needed to complement and possibly modify growth oriented policies

does poverty trap rural malagasy households this paper studies the determinants of poverty dynamics in several rural areas from madagascar a particular attention is devoted to testing if rural poverty persistence in madagascar could be explained by a vicious circle leading to a poverty trap annual poverty transitions retrieved from an original household panel data survey covering the 1996 2006 periods show that differences in household and environment characteristics are clearly associated with di erences in poverty transitions probabilities poverty vulnerable households have higher dependency ratio and are less educated they also show different income generating activities pattern they cultivate less market oriented crops and have more vulnerable activities such as agricultural wage work a markovian poverty transition model is used to evaluate the role of past poverty in this situation past poverty is allowed to have both an intercept and a slope effect on poverty transitions probabilities our results show that a substantial share of the di erences in household poverty transitions probabilities is attributable to past poverty status these results encourage the development of social protection to prevent households to fall into a poverty trap as well as speciffic measures to encourage paths out of poverty traps francais cet article etudie les determinants de la dynamique de la pauvrete dans plusieurs zones rurales de madagascar une attention particuliere est portee a l identification d un eventuel effet deletere de la pauvrete passee sur la pauvrete future pouvant conduire a un cercle vicieux de perpetuation de la pauvrete le papier se base sur l etude des transitions annuelles sur et sous le seuil de pauvrete observees sur un panel de menages ruraux malgaches entre 1996 et 2006 un modele markovien est utilise pour evaluer le role des caracteristiques des menages de l environnement et de la pauvrete passee dans la probabilite de passer sur ou sous le seuil de pauvrete les resultats montrent que certaines caracteristiques des menages et de l environnement sont clairement associees a differences dans les probabilites de transitions sur et sous le seuil de pauvrete en particulier les menages vulnerables a la pauvrete ont un rapport de dependance plus eleve sont moins eduques et ont une composition de revenus differentes ils sont notamment moins orientes vers les cultures agricoles et plus orientes vers des activites precaires comme le salariat agricole un effet deletere de la pauvrete passee sur le risque d etre pauvre dans le futur est egalement mis en evidence il passe a la fois par un effet de pente et un effet de niveau ces resultats soulignent la necessite de mettre en place des politiques specifiques contre la vulnerabilite a la pauvrete d une part et contre la pauvrete de long terme d autre part

expected poverty under risk induced welfare variability two of the most widely accepted stylised facts about agriculture in south asia sub saharan africa and elsewhere are that income is highly uncertain from one year to another and that deep and widespread poverty exists and yet there has been very little analysis of the joint problems of poverty and risk this paper offers a methodological approach to the issue of how risk affects poverty and applies it to household level data for dry areas of rural india the following questions are addressed under what conditions can one expect an increase in the riskiness of an income or consumption stream to increase poverty how should one measure the contribution of risk to poverty and what long term benefits in terms of reduced poverty can be expected from policies aimed at stabilising incomes of the poor such policies have been widely discussed in the indian subcontinent of late and their effect on rural

is transient poverty different evidence for rural china we define transient poverty as the component of time mean consumption poverty at household level that is directly attributable to variability in consumption this can be thought of as a measure of vulnerability to falling consumption the non transient component then depends solely on mean consumption over time and we call this chronic poverty using robust semi parametric methods and household panel data for rural china we test whether transient poverty is determined by a process that is similar to chronic poverty commonly identified causes of poverty in this setting have weak explanatory power for transient poverty and some of the factors determining transient poverty do not matter to chronic poverty or even have the opposite effect successful policy responses to chronic poverty may still leave considerable transient poverty

the distribution of income shocks during crises moving beyond the simple comparisons of averages typical of most analyses of household income shocks this article employs quantile analysis to generate a complete distribution of such shocks by type of household during the 1995 crisis in mexico it compares the distributions across normal and crisis periods to see whether observed differences were due to the crisis or are intrinsic to the household types alternatively it asks whether the distribution of shocks during normal periods was a reasonable predictor of vulnerability to income shocks during crises it finds large differences in the distribution of shocks by household types both before and during the crisis but little change in their relative positions during the crisis the impact appears to have been spread fairly evenly households headed by people with less education poor single mothers or people working in the informal sector do not appear to experience disproportionate income drops either in normal times or during crises

unionization and plant closure in canada this paper examines for the first time the role of unionization as a determinant of plant closings in canada using the 1999 to 2001 canadian workplace and employee survey the paper contributes to the north american evidence by showing that the share of a plant s workers covered by collective bargaining has a robust positive partial correlation with the probability of larger plants closing for smaller plants the extent of unionization tends to be much lower and its variation plays no role in plant closure the study highlights the theoretical and statistical importance of examining closure separately for large and small plants ce memoire examine pour la premiere fois le role de la syndicalisation en tant que determinant de la fermeture d usines au canada a l aide des resultats de l enquete sur le milieu de travail et les employes de 1999 et de 2001 emte le texte contribue a enrichir le dossier qui montre qu il y a correlation positive partielle robuste entre la portion des travailleurs d usines couverts par une convention collective et la probabilite de fermeture des grandes usines pour les plus petites usines le degre de syndicalisation tend aetre plus faible et sa variation ne joue pas de role dans le processus de fermeture d usines cette etude montre l importance theorique et pratique qu il y a aetudier separement les fermetures des grandes et des petites usines

durables and wives employment yet again the literature examining the relationship between consumer durables expenditures and wives employment is analyzed several deficiencies in the literature are corrected in a revised model that is estimated with data from the 1977 1978 survey of consumer expenditures this article concludes that durables expenditures and wives employment time are complements

direct elicitation of credit constraints conceptual and practical issues with an application to peruvian agriculture abstract this article provides a methodological bridge leading from the well developed theory of credit rationing to the less developed territory of empirically identifying credit constraints we begin by developing a simple model showing that credit constraints may take three forms quantity rationing transaction cost rationing and risk rationing each form adversely affects household resource allocation and thus should be accounted for in empirical analyses of credit market performance we outline a survey strategy to directly elicit households status as unconstrained or constrained in the credit market and if constrained to further identify which of the three nonprice rationing mechanisms is at play we discuss several practical issues that arise due to the use of a combination of factual and interpretative survey questions finally using a farm level data set from peru we illustrate how the methodology can be used to estimate the impacts of credit constraints

rural livelihoods and poverty reduction strategies in four african countries this paper compares and contrasts rural livelihoods in uganda kenya tanzania and malawi with a view to informing rural poverty reduction policies within poverty reduction strategy plans prsps low household incomes in rural areas of all countries are associated with low land and livestock holdings high reliance on food crop agriculture and low monetisation of the rural economy these adverse factors are in some instances made more difficult by land sub division at inheritance declining civil security in rural areas deteriorating access to proper agronomic advice and inputs and predatory taxation by decentralised district councils better off households are distinguished by virtuous spirals of accumulation typically involving diverse livestock ownership engagement in non farm self employment and diversity of on farm and non farm income sources lessons for prsps centre on the creation of a facilitating rather than blocking public sector environment for the multiplication of non farm enterprises seeking creative solutions to the spread of technical advice to farmers and examining critically the necessity for and impact of tax revenue collection by district councils on rural incomes and enterprise

policies for sustainable development in the hillside areas of honduras a quantitative livelihoods approach in this article we use data for 376 households 1 066 parcels and 2 143 plots located in 95 villages in the hillside areas in honduras to generate information needed by decision makers to assess the needs and opportunities for public investments and design policies that stimulate natural resource conservation we develop a quantitative livelihood approach using factor and cluster analysis to group households based on the use of their main assets this resulted in seven household categories that pursue similar livelihood strategies we use a multinomial logit model to show that livelihood strategies are determined by comparative advantages as reflected by a combination of biophysical and socioeconomic variables while 92 of the rural hillsides population in honduras lives on us 1 00 capita day or less households that follow a livelihood strategy based on basic grain farming are the poorest because they often live in isolated areas with relatively poor agro ecological and socioeconomic conditions opportunities for off farm work tend to be limited in these areas and household strategies that combine on farm work with off farm work earn higher incomes per capita incomes can be increased by improving road infrastructure widening access to land policies that reduce household size and dependency ratios and adoption of sustainable land management technologies that restore soil fertility we used probit models to show that the latter can be promoted by agricultural extension programs and land redistribution investments in physical assets should be directed toward households that pursue livelihood strategies based on off farm employment or coffee production while agricultural training programs are best focused on livestock producers

in the eye of the storm the welfare impacts of a hurricane summary the impact of a large covariant shock namely hurricane mitch is examined in the context of household asset holdings in rural nicaragua utilizing household panel data from the period it is found that the hurricane did not have an adverse impact on the ownership of productive assets among the affected households on average on the other hand nonproductive asset holdings seem to have been significantly reduced a further examination confirms that the shock affected the poorest households disproportionally especially in terms of nonproductive assets finally this study presents strong suggestive evidence of a geographical poverty trap within the shock affected areas of the country

why have some indian states done better than others at reducing rural poverty the unevenness of the rise in rural living standards in the various states of india since the 1950s allowed the authors to study the causes of poverty they modeled the evolution of average consumption and various poverty measures using pooled state level data for 1957 91 they found that poverty was reduced by higher agricultural yields above trend growth in nonfarm output and lower inflation rates but these factors only partly explain relative success and failure in reducing poverty initial conditions also mattered states that started the period with better infrastructure and human resources with more intense irrigation greater literacy and lower infant mortality rates had significantly greater long term rates of consumption growth and poverty reduction by and large the same variables that promoted growth in average consumption also helped reduce poverty the effects on poverty measures were partly redistributive in nature after controlling for inflation the authors found that some of the factors that helped reduce absolute poverty also improved distribution and none of the factors that reduced absolute poverty had adverse impacts on distribution in other words there was no sign of tradeoffs between growth and pro poor distribution

poverty transition and persistence in ethiopia 1994 2004 summary this study analyzes the persistence of poverty in both rural and urban areas in ethiopia during 1994 2004 the key finding is that households move frequently in and out of poverty but the difficulty of exiting from poverty like the chance of avoiding slipping back increases with the time spent in that state and varies considerably between male and female headed households our results imply that it is important to design anti poverty policies both to hinder households from slipping into extreme poverty and to minimize the length of the poverty spell for households once they have fallen into it

social capital human capital and the community mechanism toward a conceptual framework for economists abstract for facilitating the development of a consensus on the concept of social capital among economists this paper proposes its operational definition in a way consistent with the definitions of physical and human capital and discusses the relevance on the use of the metaphor of capital for social capital further the unique characteristics in the production and accumulation of social capital in comparison with physical and human capital are identified in relation with the community which is considered the central mechanism to produce social capital the merits and drawbacks of the community relative to the market and the state are examined with the aim of identifying the conditions under which social capital can be supplied efficiently in the direction of promoting economic progress

risk financial markets and human capital in a developing country this paper explores the link between financial market incompleteness and human capital accumulation we examine how child school attendance responds to seasonal fluctuations in the income of agrarian households using panel data from rural india to pinpoint market imperfections we study responses to aggregate and idiosyncratic as well as to anticipated and unanticipated income shocks our main finding is that seasonal fluctuations in school attendance are a form of self insurance but one which does not result in a substantial loss of human capital on average

vulnerability and chronic poverty in rural sichuan abstract chinese anti poverty policy stresses the long term structural nature of rural poverty this paper shows that poverty in rural sichuan during 1991 95 was both dynamic and persistent a new measure of chronic poverty is defined as a high vulnerability to being poor and compared with traditional interpretations of chronic poverty as low mean consumption households are highly vulnerable to falling into poverty even when their average consumption is some distance above the poverty line the determinants of low mean consumption and high vulnerability appear however to be similar suggesting that policies to increase mean consumption will also reduce vulnerability

identifying vulnerability to poverty a critical survey in the economic literature on poverty various methods have been proposed for measuring a phenomenon known as vulnerability however after more than a quarter century of research no consensus has been reached on how to identify such vulnerable individuals within a given population some misunderstandings have also arisen from the overlapping of other closely related concepts such as the expectation of being poor expected poverty multi period poverty and risk exposure this paper offers a detailed conceptual discussion on vulnerability to poverty and its related elements reviewing a wide range of identifying criteria provided in the literature it is found that according to the state of the art in this field of research two key elements stand out in identifying vulnerable individuals an expected well being below the poverty line and a relevant risk of falling into poverty due to downside deviation from a reference level of well being the traditional classification of vulnerability approaches has been updated into four groups i those that stress the element of exposure to risk ii those that emphasize the element of expected poverty iii those that define vulnerability through a utility gap and iv those that are supported by a mean risk dominance criterion

unionization incomplete contracting and capital investment this article examines empirically the hypothesis that incomplete contracts and resulting opportunistic behavior over the return to sunk assets reduces investment union firm contracts are incomplete because they 1 do not prevent all actions aimed at changing the existing contract 2 cover a relatively short time period and 3 do not extend to union members yet to be hired the primary response of firms is to reduce investment in specific durable assets and also to reduce employment growth and increase debt the authors find fairly strong evidence of these effects in a sample of large publicly traded firms using firm specific measures of unionization copyright 1993 by university of chicago press

shocks and their consequences across and within households in rural zimbabwe abstract increasing attention is now being paid to poverty dynamics in developing countries this work links the extent to which households smooth consumption or smooth assets given income shocks the empirical evidence on the churning of households in and out of poverty and the possibility that temporary shocks can have permanent consequences using longitudinal data from rural zimbabwe this paper extends the discussion of these issues by disaggregating the impact of shocks by levels of asset holdings by disaggregating the impact of shocks on individual level welfare and by assessing the extent to which such shocks have permanent consequences by doing so it assesses the validity of distinguishing between asset and consumption smoothing and provides insights into whether poverty dynamics assessed at the household level provide an adequate picture of dynamics at the individual level

are the poor less well insured evidence on vulnerability to income risk in rural china the authors test how well consumption is insured against income risk in a panel of sampled households in rural china they estimate the risk insurance models by generalized method of moments treating income and household size as endogenous insurance exists for all wealth groups although the hypothesis of perfect insurance is universally rejected those in the poorest wealth decile are the least well insured with 40 percent of an income shock being passed on to current consumption by contrast consumption by the richest third of households is protected from almost 90 percent of an income shock the extent of insurance in a given wealth stratum varies little between poor and nonpoor areas

ten years of q squared implications for understanding and explaining poverty summary over the past decade there have been a number of initiatives to promote a more systematic integration of quantitative and qualitative or q squared approaches to poverty analysis in the global south and a large body of literature had emerged the objective of the article is to present a selective review of this empirical work with a view to demonstrate the value it has added for understanding and explaining poverty the evidence strongly suggests that q squared approaches have aided our understanding of the characteristics of the poor and the causes of poverty

how access to irrigation influences poverty and livelihoods a case study from sri lanka abstractthis study combines a livelihoods approach with a regression approach to quantify the effectiveness of irrigation infrastructure investment on improving people s livelihood strategies using a unique dataset based on households in southern sri lanka and a natural experimental setting we estimate from a two stage income regression model to show that irrigation access has a positive effect on income through livelihood choices we also show through qualitative approaches that factors not linked to irrigation infrastructure may contribute to changes in livelihood portfolios in addition we highlight factors that result in certain households being unable to move out of poverty despite access to the improved irrigation infrastructure

livelihoods and chronic poverty in semi arid zimbabwe abstract remoteness and geographic natural physical human and social capital are contrasted with social and political exclusion in explaining persistent rural poverty we found that persistent poverty was strongly associated with the structural poverty of zimbabwe s semi arid communal areas relative urban proximity assisted income diversification and improvement in a very poor socially and politically excluded area less excluded but remote areas remained poor but not as poor as the excluded population livelihoods changed and diversified more in the nonremote area speeding poverty reduction as measured by an index of perceived change we conclude with what policy options and sequence might support the inclusion of chronically poor people

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

pathways out of rural poverty a case study in socio economic mobility in the rural philippines exploiting unique household panel data covering a 30 year period this paper attempts to analyse the patterns of poverty exits by examining socio economic mobility in a philippines village macroeconomic growth was a major factor explaining poverty exit probabilities until the early 1980s after the 1980s poverty exit paths through agricultural ladder narrowed schooling and growth became equally important factors owing to the increased returns to schooling and labour endowments also became important for the lower but not upper social strata providing an economic incentive to have more children for the poor surprisingly we find no evidence of state dependence in poverty spells once observable factors are taken into account copyright 2007 oxford university press

social capital formation and credit access evidence from sri lanka summary while previous studies evaluate the impact of social capital on development outcomes there are very few empirical studies on determinants of social capital formation we use unique long panel data from sri lanka to examine the mechanism of social capital formation in an imperfect credit market we show that households facing credit constraints reduce investments in social capital furthermore temporal declines in investment persistently reduce general trust trust in villagers and trust in business partners while previous studies argue that social capital improves access to informal credit we show the reverse causality combining these findings suggests a potential poverty trap

poverty dynamics in brazilian metropolitan areas an analysis based on hulme and shepherd s categorization 2002 2011 abstract ever more sophisticated studies on the methodological approach and the conceptual scope of poverty have led to a consensus among scholars on the dynamic characteristic of this phenomenon in other words the existence of an in and out of privation movement of individuals and families within this context hulme and shepherd 2003 defined five groups according to the location of the punctual and average indicators of poverty vis a vis the poverty line this paper s objective is to adapt this typology to brazil using pme monthly job survey micro data for the 2002 2011 timeframe and the six brazilian metropolitan regions covered by pme as well as by estimating a multinomial logit investigate which family characteristics relate to a greater or lesser chance of belonging to each of the chronic and transitory poverty categories categorization allows observation that despite a sweeping across the board decline in the percentage of families in all poverty categories in the past decade those families always or usually poor display demographic socioeconomic access to and insertion into the labor market categories which differ from families in transitory poverty or classified as never poor moreover northeastern metropolitan regions salvador and recife have higher percentages of chronic or transitory poverty multinomial logit estimates make it possible to verify that families whose members have completed secondary schooling or college or hold a higher qualified occupation stand lesser chances of entering into or remaining in poverty results call for differentiating among poor families as they enter into or leave poverty which is tantamount to saying that the dynamics of poverty must be taken into account as public policies are drawn up
