farm productivity and rural poverty in india armed with new data we return to an old question from the pages of this journal to what extent do india s rural poor share in agricultural growth combining data from 24 household sample surveys spanning 35 years with other sources we estimate a model of the joint determination of consumption poverty measures agricultural wages and food prices we find that higher farm productivity brought both absolute and relative gains to poor rural households a large share of the gains was via wages and prices though these effects took time the benefits to the poor were not confined to those near the poverty line

term premiums in bond returns abstract this paper examines expected returns on u s treasury bills and on u s government bond portfolios expected bill returns are estimated from forward rates and from sample average returns both estimation methods indicate that expected returns on bills tend to peak at eight or nine months and never increase monotonically out to twelve months reliable inferences are limited to treasury bills and thus to maturities up to a year the variability of longer term bond returns preempts precise conclusions about their expected returns

china s uneven progress against poverty while the incidence of extreme poverty in china fell dramatically over 1980 2001 progress was uneven over time and across provinces rural areas accounted for the bulk of the gains to the poor though migration to urban areas helped the pattern of growth mattered rural economic growth was far more important to national poverty reduction than urban economic growth agriculture played a far more important role than the secondary or tertiary sources of gross domestic product gdp rising inequality within the rural sector greatly slowed poverty reduction provinces starting with relatively high inequality saw slower progress against poverty due both to lower growth and a lower growth elasticity of poverty reduction taxation of farmers and inflation hurt the poor external trade had little short term impact

measuring aggregate welfare in developing countries how well do national accounts and surveys agree in a data set for developing and transition economies the author finds that private consumption per capita based on national accounts deviates on average from mean household income or expenditure based on national sample surveys growth rates also differ systematically so that the ratio of the survey mean to the national accounts mean tends to fall over time but there are revealing exceptions to these general findings the aggregate difference in the levels is due more to income surveys than to expenditure surveys and there are strong regional effects for example the severe data problems in the transition economies of eastern europe and central asia means that there is negligible correlation in that region between growth rates from national accounts and those from household surveys

measuring global poverty why ppp methods matter abstract we present theory and evidence to suggest that in the context of analyzing global poverty the eks approach to estimating purchasing power parities yields more appropriate international comparison of real incomes than the geary khamis approach our analysis of the 1996 and 2005 international comparison project data confirms that the geary khamis approach substantially overstates the relative incomes of the world s poorest nations and this leads to misleading comparisons of poverty across regions and over time the eks index of real income is much closer to being a true index of economic welfare and is therefore preferred for assessment of global poverty

are there dynamic gains from a poor area development program poor area development programs in which the government transfers extra resources to unusually poor areas have been widely used to fight poverty there has been some research on such programs but little is known about their impact on household living standards over time the authors address the issue for a sizable poor area development program in rural china china s program had a significant impact on rural living standards in the targeted areas of the sample the consumption growth model suggests that households living in the targeted areas had a higher rate of consumption growth than one would have otherwise expected nonetheless the authors found that while the gains in growth were enough to prevent an absolute decline in average living standards they were not enough to reverse the strong underlying divergent tendencies in the rural economy

societal poverty a relative and relevant measure poverty lines are typically higher in richer countries and lower in poorer ones reflecting the relative nature of national assessments of who is considered poor in many high income countries poverty lines are explicitly relative set as a share of mean or median income despite systematic variation in how countries define poverty global poverty counts are based on fixed value lines to reflect national assessments of poverty in a global headcount of poverty this paper proposes a societal poverty line the proposed societal poverty line is derived from 699 harmonized national poverty lines and has an intercept of 1 per day and a relative gradient of 50 percent of median national income or consumption the societal poverty line is more closely aligned with national definitions of poverty than other proposed relative lines by this relative measure societal poverty has fallen steadily since 1990 but at a much slower pace than absolute extreme poverty

self rated economic welfare in russia abstract most of those russian adults who feel that they are poor are not classified as such in the poverty statistics and most of those who are classified as poor don t feel that way we study the determinants of peoples perceptions of their economic welfare in an unusually rich socioeconomic survey while income is a highly significant predictor subjective economic welfare is influenced by many other factors including health education employment assets relative income in the area of residence and expectations about future welfare insights are obtained into how objective data should be weighted in assessing economic welfare

economic inequality in the arab region the paper uses harmonized household survey micro data to assess the levels and determinants of economic inequality in 12 arab countries it focuses on the sources of rural urban as well as metropolitan nonmetropolitan inequalities and applies the unconditional quantile regression decomposition technique to analyze the welfare gaps across the entire distribution the analysis finds moderate inequality levels with the gini coefficient for the distribution of household real per capita total expenditures ranging between 30 7 in libya and 45 in mauritania differences in households endowments such as demographic composition human capital and community characteristics appear as the main sources of the urban rural welfare gap there is inequality between metropolitan and non metropolitan regions in many countries mainly because of differences in returns to households characteristics and particularly returns to human capital

when financial work incentives pay for themselves evidence from a randomized social experiment for welfare recipients abstract this paper summarizes early findings from a social experiment that provided financial incentives for new welfare recipients to leave welfare and work full time the financial incentive was essentially a negative income tax with a requirement that people work at least 30 h week early results show that the financial incentive increased full time employment earnings and income and reduced poverty furthermore at the end of the period discussed in this paper the program was paying for itself through increased tax revenues

why not consider that being absolutely poor is worse than being only relatively poor abstract no current strategy to measure income poverty is able to i account for both its absolute and relative aspects and ii always consider that an individual who is absolutely poor is poorer than another individual who is only relatively poor i propose a measure of income poverty satisfying i and ii unlike alternative proposals satisfying i a decrease in a poor individual s income never reduces this measure an application illustrates that the measure yields intuitive judgments about unequal growth experiences for which all absolute resp relative poverty measures systematically conclude that poverty has decreased resp increased

when does economic growth reduce poverty and strengthen the middle class a state level sector specific analysis of peru using novel state level data of peru from 1997 to 2010 we investigate how growth in different sectors affects poverty rates and the middle class our results indicate that only the manufacturing sector seems to robustly decrease poverty growth in the service sector emerges as a meaningful predictor of a rising middle class allowing for regional differences we find substantial variation across the 25 peruvian states with large shifts in magnitudes signs and statistical importance beyond the immediate implications for peru these findings highlight the importance of analyzing the link between economic performance and poverty rates on a subnational level policy implications are likely to differ substantially depending on the source of economic growth and regional particularities

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

true world income distribution 1988 and 1993 first calculation based on household surveys alone the paper derives world income or expenditure distribution of individuals for two years 1988 and 1993 it is the first paper to calculate world distribution for individuals based entirely on household survey data from 91 countries and adjusted for differences in purchasing power parity between the countries measured by the gini index inequality increased from an already very high 63 in 1988 to 66 in 1993 the increase was driven more by rising differences in mean incomes between the countries than by rising inequalities within countries the most important contributors were rising urban rural differences in china and slow growth of rural incomes in south asia compared to several large developed market economies

the distributional impacts of an energy boom in western canada in the energy rich region of western canada inequality rose over the past two decades while poverty declined begging the question of whether the recent energy boom was a contributing factor this study uses measures of inequality and poverty across local labor markets that vary in energy extraction intensity to identify these distributional impacts the evidence shows that overall the boom increased inequality and decreased poverty there are however a few notable cases where these relationships are reversed the significance and relative magnitude of growth across and between distributional segments were consistent with these findings

why has economic growth been more pro poor in some states of india than others abstract we use 20 household surveys for india s 15 major states spanning 1960 1994 to study how the sectoral composition of economic growth and initial conditions interact to influence how much growth reduced consumption poverty the elasticities of measured poverty to farm yields and development spending did not differ significantly across states but the elasticities of poverty to urban and rural non farm output varied appreciably and the differences were quantitatively important to the overall rate of poverty reduction states with higher elasticities did not experience higher rates of non farm growth the non farm growth process was more pro poor in states with initially higher literacy higher farm productivity higher rural living standards relative to urban areas lower landlessness and lower infant mortality

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

do poverty traps exist assessing the evidence why did per capita incomes not increase in burundi haiti and nicaragua countries one possible explanation is a poverty trap which can be understood as a set of self reinforcing mechanisms whereby countries start poor and remain poor poverty begets poverty so that current poverty is itself a direct cause of poverty in the future it implies that much poverty is needless in the sense that a different equilibrium is possible and also that one time policy efforts that break the poverty trap may have lasting effects the concept of a poverty trap at the level of national economies is related to and sometimes based on microeconomic foundations that argue for the existence of poverty traps at the household level the authors discuss behavioral poverty traps as a recent area of research for which the evidence is just starting to accumulate and geographic poverty traps as the most likely form of a trap the policy prescriptions that result are then quite different from the calls for a big push in aid or expansion of microfinance to allow people to overcome credit constraints

you are what and where you eat capturing food away from home in welfare measures consumption of food away from home is rapidly growing across the developing world surprisingly the majority of household surveys around the world haven not kept up with its pace and still collect limited information on it the implications for poverty and inequality measurement are far from clear and the direction of the impact cannot be established a priori since consumption of food away from home affects both food consumption and the poverty line this paper exploits rich data on food away from home collected as part of the national household survey in peru shedding light to the extent to which welfare measures differ depending on whether they properly account for food away from home peru is a relevant context with the average peruvian household spending 28 percent of their food budget on food away from home by 2010 the analysis indicates that failure to account for the consumption of food away from home has important implications for poverty and inequality measures as well as the understanding of who the poor are first accounting for food away from home results in extreme poverty rates that are 18 percent higher and moderate poverty rates that are 16 percent lower these results are also consistent in fact more pronounced with poverty gap and severity measures second consumption inequality measured by the gini coefficient decreases by 1 3 points when food away from home is included a significant reduction finally inclusion of food away from home results in a reclassification of households from poor to non poor status and vice versa 20 percent of the poor are different when the analysis includes consumption of food away from home this effect is large enough that a standard poverty profile analysis results in significant differences between the poverty classification based on whether food away from home is included or not the differences cover many dimensions including demographics education and labor market characteristics taken together the results indicate that a serious rethinking of how to deal with the consumption of food away from home in measuring well being is urgently needed to properly estimate and understand poverty around the world

global inequality when unequal countries create unequal people abstract current global inequality measures assume that national mean income does not matter to economic welfare at given household income as measured in surveys the paper questions that assumption on theoretical and empirical grounds and finds that prominent stylized facts about global inequality are not robust at one extreme theories of relative deprivation yield nationalistic measures whereby global inequality is average within country inequality which is rising however other theories and evidence point instead to the benefits of living in a richer country parameter values consistent with research on global subjective wellbeing imply higher inequality than prevailing measures though falling since 1990

what can new survey data tell us about recent changes in distribution and poverty it has been claimed that in recent times the poor have lost ground both relatively and absolutely even when average levels of living have risen this article tests that claim using household surveys for 67 developing and transitional economies over 1981 94 it finds that changes in inequality and polarization were uncorrelated with changes in average living standards distribution improved as often as it worsened in growing economies and negative growth was often more detrimental to distribution than positive growth overall there was a small decrease in absolute poverty although with diverse experiences across regions and countries almost always poverty fell with growth in average living standards and rose with contraction

the evolving role of agriculture in poverty reduction an empirical perspective abstract the role of agriculture in development remains much debated this paper takes an empirical perspective and focuses on poverty as opposed to growth alone the contribution of a sector to poverty reduction is shown to depend on its own growth performance its indirect impact on growth in other sectors the extent to which poor people participate in the sector and the size of the sector in the overall economy bringing together these different effects using cross country econometric evidence indicates that agriculture is significantly more effective in reducing poverty among the poorest of the poor as reflected in the 1 day squared poverty gap it is also up to 3 2 times better at reducing 1 day headcount poverty in low income and resource rich countries including those in sub saharan africa at least when societies are not fundamentally unequal however when it comes to the better off poor reflected in the 2 day measure non agriculture has the edge these results are driven by the much larger participation of poorer households in growth from agriculture and the lower poverty reducing effect of non agriculture in the presence of extractive industries

the relation between forward prices and futures prices abstract this paper consolidates the results of some recent work on the relation between forward prices and futures prices it develops a number of propositions characterizing the two prices these propositions contain several testable implications about the difference between forward and futures prices many of the propositions show that equilibrium forward and futures prices are equal to the values of particular assets even though they are not in themselves asset prices the paper then illustrates these results in the context of two valuation models and discusses the effects of taxes and other institutional factors

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

the politics of staying poor exploring the political space for poverty reduction in uganda summary despite claims that uganda s recent success in poverty reduction has been significantly related to getting the politics right there are concerns that the poorest may not have benefited from this form of poverty reduction or the types of politics that have helped shape it employing the analytical framework of political space reveals that although some of the poorest groups are represented within the political system political discourse reveals a strong bias toward the economically active leaving the poorest excluded from poverty programs significantly there is an increasing divergence between the regime s political project of modernization and the international poverty agenda with important implications for the poorest

global poverty estimates a sensitivity analysis summary current estimates of global poverty vary substantially across studies we undertake a sensitivity analysis to highlight the importance of methodological choices by measuring global poverty using different data sources parametric and nonparametric estimation methods and multiple poverty lines our results indicate that estimates of global poverty vary significantly when they are based alternately on data from household surveys versus national accounts but are relatively consistent across estimation methods the decline in poverty over the past decade is found to be robust across methodological choices

growth and poverty evidence for developing countries in the 1980s abstract measures of consumption poverty for a sample of developing countries in the 1980s respond elastically to changes in mean consumption although there is a high variance in poverty outcomes at a given rate of growth there is no sign of systematic effects of growth on inequality

banking development socioeconomic structure and income inequality abstract using rich unique data from the italian local credit markets provinces this paper investigates the impact of local banking development on income inequality and the role of the socioeconomic structure in this link exploiting the italian historical banking regulation to instrument for the local presence of bank branches we find that local banking development mitigates income inequality however the finance inequality nexus manifests itself only in relatively advanced areas when we study the structural channels of influence we uncover evidence that banking development can reduce inequality by affecting geographical mobility and urbanization while it has modest effects through the development of material infrastructures and human capital

poverty reduction strategy papers a new convergence abstract poverty reduction strategy papers represent both a primary policy device of international development institutions and an instance of a wider international convergence of public policy around global integration and social inclusion charting the emergence of these approaches this paper argues that this convergence has a number of structural predilections which favor the technical and juridical over the political economic and a disciplinary framework over a practical contest drawing extensively on decentralized governance and poverty reduction programs in uganda this paper shows how these predilections obscure power relations and restrict practical and political options while exacting heavy establishment and compliance costs

weakly relative poverty prevailing measures of relative poverty are unchanged when all incomes grow or contract by the same proportion this property stems from seemingly implausible assumptions about the disutility of relative deprivation and the cost of social inclusion the authors propose weakly relative lines that relax these assumptions on calibrating our measures to national poverty lines and survey data we find that half the population of the developing world in 2005 lived in poverty only half of whom were absolutely poor the total number of poor rose over 1981 to 2005 despite falling numbers of absolutely poor with sustained economic growth the incidence of relative poverty became less responsive to further growth the number of relatively poor rose just as the numbers of absolutely poor fell

community comparisons and subjective well being in a divided society using a south african data set the paper poses six questions about the determinants of subjective well being much of the paper is concerned with the role of relative concepts we find that comparator income measured as average income of others in the local residential cluster enters the household s utility function positively but that income of more distant others others in the district or province enters negatively the ordered probit equations indicate that as well as comparator groups based on spatial proximity race based comparator groups are important in the racially divided south african society it is also found that relative income is more important to happiness at higher levels of absolute income potential explanations of these results and their implications are considered

can the paris deal boost sdgs achievement an assessment of climate mitigation co benefits or side effects on poverty and inequality abstract the paper investigates potential synergies and trade offs between emission reduction policies and sustainable development objectives specifically it provides an ex ante assessment that the impacts of the nationally determined contributions ndcs submitted under the paris agreement will have on the sustainable development goals sdgs of poverty eradication sdg1 and reduced income inequality sdg10 through this research we aim at answering the following questions does mitigation policy always imply a trade off with development objectives if this is the case what is the magnitude of the effect of the new international climate architecture on poverty and inequality by combining an empirical analysis with a modelling exercise the paper estimates the future trends of poverty prevalence and inequality across countries in a reference scenario and under a climate mitigation policy with alternative revenue recycling schemes our study finds that a full implementation of the emission reduction contributions stated in the ndcs is projected to slow down the effort to reduce poverty by 2030 4 2 of the population below the poverty line compared to the baseline scenario especially in countries that have proposed relatively more stringent mitigation targets and suffer higher policy costs conversely the impact of climate policy on inequality shows opposite sign but remains very limited if financial support for mitigation action in developing countries is provided through an international climate fund the prevalence of poverty will be slightly reduced at the aggregate level but the country specific effect depends on the relative size of funds flowing to beneficiary countries and on their economic structure the output of our analysis contributes to the emerging literature on the linkages between climate change policy and sustainable development although we capture only partially the complex system of interrelations and feedbacks proper of the sdgs moreover due to its policy relevance it further enriches the debate on the implementation of the paris agreement and its climate finance tools

the developing world is poorer than we thought but no less successful in the fight against poverty a new data set on national poverty lines is combined with new price data and almost 700 household surveys to estimate absolute poverty measures for the developing world we find that 25 of the population lived in poverty in 2005 as judged by what poverty typically means in the world s poorest countries this is higher than past estimates substantial overall progress is still indicated the corresponding poverty rate was 52 in 1981 but progress was very uneven across regions the trends over time and regional profile are robust to various changes in methodology though precise counts are more sensitive

differentials at firm level productive capacity realization in bangladesh food manufacturing an empirical analysis this article empirically estimates the firm specific productive capacity realization pcr indices using the stochastic frontier production function and analyses a number of variables explaining realization rates across firms and over time following battese and coelli 1995 the stochastic frontier production function is used to estimate capacity output and thereby pcr using the firm level panel data from bangladesh food manufacturing the results show that capacity realization rates widely vary across firms and over time the average rate of realization is about 65 implying that most of the firms are producing away from their full production capacity this article also identifies several firm specific and policy related variables explaining capacity realization the results show that firm size sze and outward orientation opn have positive while capital intensity cnsty market structure mstre and effective rate of assistance era have negative impact on realization rates strikingly both poli

an unconditional quantile regression based decomposition of spatial welfare inequalities in ghana abstractghana has witnessed tremendous economic growth since the 1990s and attained the millennium development goals target of halving poverty this notwithstanding inequality in ghana increased over the same period suggesting growth benefits were not equitably distributed this study provides evidence on the determinants of household consumption expenditure and factors that explain rural urban welfare gaps between 1998 and 2013 the study employs an unconditional quantile regression and recently proposed decomposition technique based on re centred influence functions we find significant spatial differences in consumption expenditure across selected quantiles with rural urban inequalities driven largely by differences in returns to households endowments

poverty reduction without economic growth explaining brazil s poverty dynamics 1985 2004 brazil s slow pace of poverty reduction over the last two decades reflects both low growth and a low growth elasticity of poverty reduction using gdp data disaggregated by state and sector for a twenty year period this paper finds considerable variation in the poverty reducing effectiveness of growth across sectors across space and over time growth in the services sector was substantially more poverty reducing than was growth in either agriculture or industry growth in industry had very different effects on poverty across different states and its impact varied with initial conditions related to human development and worker empowerment the determinants of poverty reduction changed around 1994 positive growth rates and a greater absolute elasticity with respect to agricultural growth contributed to faster poverty reduction but because there was so little of it economic growth played a relatively small role in accounting for brazil s poverty reduction between 1985 and 2004 the taming of hyperinflation in 1994 and substantial expansions in social security and social assistance transfers beginning in 1988 accounted for a larger share of the overall reduction in poverty

growth elasticity of poverty direct estimates from recent data using recent poverty data for developing countries elasticity of 2 poverty headcount with respect to the growth of gross domestic product gdp per capita is directly calculated for the 1990s and the 2000s the global estimate is around 0 84 which is much smaller in absolute magnitude than what some highly influential studies have reported or used for the poverty dense south asia region the elasticity is of the order of 0 22 which is a dramatic contrast from the previous estimates for india where the number of poor people is by far the largest of any country and where the poverty rate is higher than even in sub saharan africa ssa the elasticity is of the order of 0 13 which is an even bigger contrast from earlier studies policymakers and researchers are urged to keep these estimates in mind while judging the likely effect of income growth on poverty and to discount poverty reduction claims based on higher elasticity estimates that have been reported or used in many influential studies i

pricing term structure risk in futures markets one period expected returns on futures contracts with different maturities differ because of risk premia in the spreads between futures and spot prices we analyze the expected returns for futures contracts with different maturities using the information that is present in the current term structure of futures prices a simple affine one factor model that implies a constant covariance between the pricing kernel and the cost of carry cannot be rejected for heating oil and german mark futures contracts for gold and soybean futures the risk premia depend on the slope of the current term structure of futures prices while for live cattle futures the evidence is mixed

macro and micro perspectives of growth and poverty in africa this article reviews trends in poverty economic policies and growth in a sample of african countries during the 1990s drawing on the better household data now available experiences have varied some countries have seen sharp drops in income poverty whereas others have witnessed marked increases in some countries overall economic growth has been pro poor and in others not but the aggregate numbers hide systematic distributional effects taking both macro and micro perspectives of growth and poverty in africa the article draws four key conclusions first economic policy reforms improving macroeconomic balances and liberalizing markets appear conducive to reducing poverty second market connectedness is crucial to enable participation in the gains from economic growth some regions and households by virtue of their remoteness were left behind when growth picked up third education and access to land emerge as key private endowments to help households benefit from new economic opportunities finally rainfall variations and ill health have profound effects on poverty outcomes underscoring the significance of social risk management in poverty reduction strategies in africa

international redistribution of income summary how do international policies on aid trade and factor movements affect the international distribution of income we calculate the impact by world decile of the actual level of aid flows and the effect on income of merchandise trade restrictions by high income countries we find that aid s distributional impact is equality enhancing extremely small in terms of changes in inequality measures but of some importance for the lowest decile of the distribution we also find that some of this impact is counteracted by lost potential income in the lower deciles from merchandise trade barriers imposed by high income countries

mean reversion in equilibrium asset prices evidence from the futures term structure we use the term structure of futures prices to test whether investors anticipate mean reversion in spot asset prices the empirical results indicate mean reversion in each market we examine for agricultural commodities and crude oil the magnitude of the estimated mean reversion is large for example point estimates indicate that 44 percent of a typical spot oil price shock is expected to be reversed over the subsequent eight months for metals the degree of mean reversion is substantially less but still statistically significant we detect only weak evidence of mean reversion in financial asset prices in this study we provide evidence of mean reversion in the prices of several real and financial assets rather than examining evidence of ex post reversion using time series of asset prices we use price data from futures contracts with varying delivery horizons to test whether investors expect asset prices to revert this approach offers two advantages first since futures prices are readily available for many markets our procedure can be implemented for many assets including those for which reliable spot price data is elusive second there is little ambiguity as to the source of any mean reversion detected using our method subject only to the maintained assumption that the no arbitrage cost of carry condition holds our test detects mean reversion that is expected to occur in equilibrium but has no power to detect mean reversion resulting from noise or inefficiencies our methodology focuses on relations between price levels and the slope of the futures term structure defined as the change across delivery dates in the futures prices observed on a given trading date an inverse relation between prices and the futures term slope constitutes evidence that investors expect mean reversion in spot prices to illustrate initially assume there are no

channels and policy debate in the globalization inequality poverty nexus the process of globalization has led to a much greater integration of the world economy the flows of trade capital labour technology and information across national borders have accelerated since the 1980s and created an environment conducive to faster economic growth and transmission of knowledge it is evident that the forces of globalization provide a strong potential for a major reduction in poverty in the developing world however for a number of reasons brought out in this chapter the positive impact of globalization on poverty alleviation worldwide has not been as substantial as one might have expected in this chapter we explore structural factors and policies within the world economy and national economies that impede the full transmission of the benefits of the various channels of globalization to poverty reduction

economic reforms and productive capacity realisation in bangladesh an empirical analysis using firm level data from the bangladesh food manufacturing sector this paper examines the impact of economic reform on productive capacity realisation in the eighties the results suggest that although improvement occurred in the realisation of productive capacities after the implementation of economic reforms there is however room for significant further improvement in increasing output by realising the unrealised capacity

technical efficiency effects of input controls evidence from australia s banana prawn fishery this paper provides the first ex post estimates of the effects of input controls on technical efficiency in a fishery using individual vessel data from the northern prawn fishery of australia for the years 1990 1996 and 1994 2000 stochastic production frontiers are estimated to analyse the efficiency impacts of input controls on engine and vessel size the results indicate that technical efficiency is increasing in a measure of vessel size and engine capacity that was controlled by the regulator from 1985 to 2001 and decreasing in an unregulated input gear headrope length the study shows that fishers have substituted from regulated to unregulated inputs over the period 1990 2000 and technical efficiency has declined coincident with increasing restrictions on vessel size and engine capacity the decline in technical efficiency indicates that the goal of the regulator to increase economic efficiency has not been realized

exchange rates productivity poverty and inequality this article analyses differences in the wealth of nations by comparing ppp based cross country incomes from the penn world table with those derived from prevailing exchange rates using the balassa 1964 samuelson 1964 productivity bias framework we introduce the international poverty line and illustrate the implications for cross country income inequality we demonstrate that our results are not inconsistent with the previous literature when appropriately interpreted

on the impact of trade openness on growth further evidence from oecd countries this study attempts to examine empirically the implications of the degree of openness for total and individual factor productivity growth in a group of 19 oecd countries over the last three decades the study combines both time series and cross sectional data the model employed is a generalization of the commonly used growth accounting model based on the concept of an aggregate production function in which the rate of economic growth is a function of capital and labour accumulation and total factor productivity it is explicitly assumed that total factor productivity depends in turn upon the rate of export expansion the model is then estimated using the random coefficients approach while results generally indicate that the relative importance of trade openness on economic growth varies significantly across countries they also indicate that the role of capital and labour accumulation in fostering economic growth varies with the degree of openness cross sectionally as well as across time

can high inequality developing countries escape absolute poverty do the poor face the same prospects for escaping poverty in high inequality developing countries as in low inequality countries is it possible for inequality to be so great as to stifle prospects of reducing absolute poverty even when other initial conditions and policies are favorable to growth household survey data for developing countries suggest that initial distribution does affect how much the poor share in rising average incomes higher initial inequality tends to reduce growth s impact on absolute poverty by the same token higher inequality diminishes the adverse impact on the poor of general economic contraction combining this evidence with that from recent investigations of inequality s effect on growth the author finds that if inequality is high enough countries that would have very good growth prospects at low levels of inequality may see little or no overall growth and little progress in reducing poverty or even a worsening on both counts the data the author uses suggest that such cases do occur the precision with which key parameters have been estimated makes it difficult to say with confidence how common such cases are but they appear to be in the minority what appear to be the best available estimates suggest that about one fifth of the spells between surveys he analyzed were cases in which poverty was rising yet positive growth in the mean and hence falling poverty is predicted at zero inequality inequality can be high enough to result in rising poverty despite good underlying growth prospects

asset inequality matters an assessment of the world bank s approach to poverty reduction the fight against poverty has been adopted by the multilateral development banks as their principal objective almost three decades after robert mcnamara announced that the world bank s fundamental work was to improve the lives of the poor its new president james wolfensohn has reiterated that poverty reduction is the world bank s principal purpose similarly in 1994 the inter american development bank set social progress and social equity as its central objective the emphasis in the international institutions contrasts with disappointing results in the real world although life expectancy school enrollmuent and other indicators of social wellbeing have improved dramatically across the developing world and although the proportion of the poor has declined in the last few decades the absolute number of poor people in the world has actually increased today about 1 3 billion people in less developed countries still subsist on less than 1 per day world bank 1980 1990 1996 the case of latin america is dramatic while in the 1970 s the number of poor fell it nearly doubled in the 1980 s increasing from about 80 to almost 150 million and in the last few years the number of poor now 33 percent of the total population has failed to fall despite economic recovery birdsall and londofio 1997 the contrast between the multilateral banks goals and these disappointing results suggests the need for a critical reassessment of their approach to poverty reduction in this paper we describe the approach reflected in the work of world bank economists and based on new empirical work assess its relevance for latin america

economic mobility and poverty dynamics in developing countries this study provides an introduction to this special issue of the journal of development studies on economic mobility and poverty dynamics in developing countries in addition to providing a conceptual framework it outlines how the contributions fit into the extant literature a series of regularities emerge across these studies the poor consist of those who are always poor poor at all dates and those who move in and out of poverty with the latter group tending to be strikingly large such movements in and out of poverty are apparent when looking at poverty in either absolute or relative terms changes in returns to endowments can be a potent source of increased incomes finally seemingly transitory shocks can have long term consequences the study concludes by drawing out the policy implications of these regularities

measuring and assessing capacity utilization in the manufacturing sectors of nine oecd countries following a tradition established by cassels klein and hickman we employ the economic theory of cost and production and define economic capacity output as that output at which short and long run average total cost curves are tangent to one another capacity utilization cu rates are then computed as the ratio of actual to capacity output we implement this framework empirically by specifying and estimating a translog variable cost function for the manufacturing sectors of nine oecd countries we find that by the end of the historical sample the early 1980s pervasive and chronic excess capacity exists while the average cost consequence of excess capacity was relatively modest in the 1960s the burden increased considerably after opec i and after opec ii the premium was as large as 15 of average total costs we also find that electricity and fuel price increases had small impacts on capacity output relative to that from labor or capital finally we adjust conventional measures of multifactor productivity growth for changes in cu and find that the adjusted growth is larger after 1973 than that based on traditional procedures

measuring poverty using qualitative perceptions of consumption adequacy we show that subjective poverty lines can be derived using simple qualitative assessments of perceived consumption adequacy based on a household survey we implement the method using survey data for jamaica and nepal respondents were asked whether their consumptions of food housing and clothing were adequate for their family s needs the implied poverty lines are robust to alternative methods of dealing with other components of expenditure the aggregate poverty rates accord quite closely with those based on independent objective poverty lines however there are notable differences in the geographic and demographic poverty profiles

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

foreign direct investment spillovers and technical efficiency in the indonesian pharmaceutical sector firm level evidence the spillovers of foreign direct investment fdi on domestic firms performances have been highly debated for many years this article contributes to this debate by analysing spillovers effects on technical efficiency of indonesian pharmaceutical sector using a unique unbalanced panel of highly disaggregated at five digit international standard industrial classification isic 210 firms over the period 1990 1995 1001 observations the stochastic production frontier spf and the data envelopment analysis dea based on malmquist productivity indices mpi have been used to test the spillovers effects of fdi on technical efficiency the empirical results from the spf show that foreign firms are more efficient than domestic competitors and the presence of the former increases the inefficiency of the latter similarly the results from the mpi demonstrate that fdi has a negative and significant impact on technical efficiency changes in domestic competitors but generate positive spillovers to domestic s

new ways of looking at old issues inequality and growth abstract the paper uses new cross country data on income and asset land distribution to show that i there is a strong negative relationship between initial inequality in the asset distribution and long term growth ii inequality reduces income growth for the poor but not for the rich and iii available longitudinal data provide little support for the kuznets hypothesis policies that increase aggregate investment and facilitate acquisition of assets by the poor might thus be doubly beneficial for growth and poverty reduction

the economic lives of the poor in what turned out to be a rhetorical master move the 1990 world development report from the world bank defined the extremely poor people of the world as those who are currently living on no more than 1 per day per person measured at the 1985 purchasing power parity ppp exchange rate in 1993 the poverty line was updated to 1 08 per person per day at the 1993 ppp exchange rate which is the line we use in this paper poverty lines have always existed indeed 1 per day was chosen in part because of its proximity to the poverty lines used by many poor countries 1 however the 1 a day poverty line has come to dominate the conversations about poverty to a remarkable extent

impact of financial crises on poverty in developing world an empirical approach in this paper we adopt a cross country perspective to analyze the short term effects of currency banking and debt crises on poverty we employ multivariate fixed effects panel data analysis in order to examine whether and to what extent different types of financial crises impact the poverty headcount ratio and the poverty gap as measured by the world bank our findings suggest that out of the three categories of financial crises we identify it is currency crises that most significantly exacerbate both the incidence and depth of poverty in the short run we find evidence that banking crises are associated with an increase in the depth of poverty but not the incidence however this effect tends to be short lived while our analysis shows no direct effect of sovereign debt crises on short term poverty

financial inclusion gender dimension and economic impact on poor households summary we examine the question in the context of gender dimension what is the evidence of the impact of the financial inclusion programs on poor households represented by women relative to that represented by men by constructing a good counterfactual and comparison group we employ the difference in difference estimator approach with panel least squares and generalized methods of moments using standard errors for a robust analysis we notice that income growth cagr net of inflation effect was 8 40 for women as against 3 97 for men indicating that the gender of participating poor undoubtedly affects the outcomes of these programs

does aggregation hide the harmful effects of inequality on growth abstract aggregation can severely bias conventional tests of whether inequality impedes growth a micro growth model estimated on farm household data for rural china indicates that asset inequality in the area of residence has a harmful external effect on consumption growth the effect is lost in a regional growth regression

growth is good for whom when how economic growth and poverty reduction in exceptional cases summary economic growth and liberal economic policies often help the poor but what about the numerous cases in which they do not this article analyzes two types of cases those in which income growth of the poor was significantly lower than expectations negative exceptions and those in which income growth of the poor significantly exceeded expectations positive exceptions insights from these cases inform our theoretical understanding of poverty reduction in addition this article contributes a typology of strategies used in these cases including alternative pathways to economic growth and neoliberal prescriptions for poverty reduction

roads out of poverty assessing the links between aid public investment growth and poverty reduction the authors develop a macroeconomic framework that captures links between aid public investment growth and poverty public investment is disaggregated into education infrastructure and health and affects both aggregate supply and demand dutch disease effects are captured by accounting for changes in the relative price of domestic goods the authors assess the impact of policy shocks on poverty by linking the model to a household survey they calibrate the model for ethiopia and simulate the changes in the allocation of aid and public investment the authors also calculate the amount by which foreign aid should increase to reach the poverty targets of the millennium development goals

trade openness and economic growth a cross country empirical investigation abstract this paper demonstrates that trade liberalization does not have a simple and straightforward relationship with growth using a large number of openness measures for a cross section of countries over the last three decades we use two groups of trade openness measures the regression results for numerous trade intensity ratios are mostly consistent with the existing literature however contrary to the conventional view on the growth effects of trade barriers our estimation results show that trade barriers are positively and in most specifications significantly associated with growth especially for developing countries and they are consistent with the findings of theoretical growth and development literature

ethnic inequality and poverty in malaysia since may 1969 part 2 poverty abstract over the last 50 years malaysia has seen one of the fastest rates of income poverty reduction in the world this came alongside falling overall income inequality due in large part to a national policy effort to address ethnic inequalities in the wake of tragic race riots in 1969 the first paper in the two part series examined various measures of ethnic inequality this second paper assesses the role that changes in between group inequality played in malaysia s success against poverty to address this question a new decomposition method is applied to survey data spanning 50 years the results indicate that ethnic redistribution helped reduce poverty but it was not as important as within group redistribution or mean income growth a pure ethnic redistribution effect is defined and isolated empirically sizable potential gains to the country s poor from ethnic redistribution are revealed in the 1970s suggesting that the early policy effort made sense the absolute gains have faded over time and are now small though the elasticity of national poverty to ethnic redistribution remains quite high

reasonable expectations and the first millennium development goal how much can aid achieve summary using a calibrated neoclassical growth model we address three questions i how much growth should aid flows have produced in sub saharan africa over the last three decades ii how much aid would be needed to attain the first millennium development goal mdg 1 of cutting poverty in half by 2015 iii taking proposed aid flows as given how much would structural characteristics such as domestic savings rates and productivity have to change in order to reach the mdg 1 our analysis indicates that past and future expectations for aid in fostering growth and poverty reduction have been too high

explaining international and intertemporal variations in income inequality this paper explores the propositions that income inequality is relatively stable within countries and that it varies significantly among countries a new and expanded data set provides broad support for both propositions drawing on a political economy and capital market imperfection arguments to explain the intertemporal and international variation in inequality the empirical analysis shows that the predicted variables associated with the first argument a measure of civil liberties and the initial level of secondary schooling and the second argument a measure of financial depth and the initial distribution of land are indeed important determinants of inequality this paper explores two propositions regarding income inequality they are first income inequality is relatively stable within countries and second it varies significantly across countries to illustrate note that the gini coefficient in india remained almost constant for forty years 1951 92 with mean 32 6 and standard deviation 2 0 2 in contrast the variation in gini coefficients across countries is large 61 9 in honduras in 1968 compared with 17 8 in bulgaria in 1976 if substantiated these propositions have potentially significant implications for poverty the significance of the first is obvious barring any fundamental socio political change poverty reduction will depend crucially on the rate of economic growth given this the significance of the second is that in inegalitarian economies the poor will enjoy a smaller share of any national increment in income than in more egalitarian ones drawing on a new and expanded data set on inequality deininger and squire 1996a the first of the paper s three sections conducts standard statistical tests of the two propositions the sample comprises 573 observations on the most common measure of inequality the gini coefficient for 49 developed and developing countries covering the period 1947 94 the results broadly confirm our two propositions specifically analysis of variance anova shows that about 90 of the total variance in the gini coefficients

production technologies and technical efficiency evidence from portuguese manufacturing industry this paper aims to test whether a given type of process innovation namely flexible production technologies fpts contributes to increased firm efficiency using one year firm data from the portuguese manufacturing industry and applying a parametric stochastic frontier approach individual technical efficiencies are obtained and their determinants simultaneously estimated using a single step procedure recently proposed by battese and coelli 1995 the results support the hypothesis that technological flexibility measured through the use of fpts is important in explaining differences in efficiency furthermore given the specifications of the stochastic frontier function the null hypothesis that portuguese firms are fully technically efficient is rejected

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

comparative productivity of korean manufacturing 1967 1987 this paper compares productivity levels in south korean manufacturing with those in the usa for 13 manufacturing branches the comparison is based on specific industry of origin purchasing power parities value added per hour worked in korean manufacturing rose from only 4 5 percent of the us level in 1967 to more than 18 percent in 1987 total factor productivity rose from only 9 percent in 1967 to 26 percent of the us level in 1987 at a more detailed level especially the leather metals and machinery industries have reached high productivity levels some of which approach levels in european manufacturing the considerable labour productivity gap between korea and the united states can partly be explained by capital intensity structural effects size effects and levels of education

on the measurement of capacity utilization capacity utilization is usually defined as the ratio of actual output to the output corresponding to 1 the minimum point on the short run average total cost curve and 2 the point of tangency between the long run average total cost and short run average total cost curves in practice however capacity utilization is often measured as the ratio of actual to the maximum potential output consistent with a given capital stock this paper demonstrates how to estimate the theoretical measures of capacity utilization and examines the correlation between three measures of capacity utilization and the mcgraw hill estimates of capacity utilization using data from a sample of u s privately owned electric utilities for 1961 83 copyright 1989 by blackwell publishing ltd

measuring poverty in a growing world or measuring growth in a poor world the extent to which growth reduces global poverty has been disputed for 30 years although there are better data than ever before controversies are not resolved a major problem is that consumption measured from household surveys which is used to measure poverty grows less rapidly than consumption measured in national accounts in the world as a whole and in large countries particularly india china and the united states in consequence measured poverty has fallen less rapidly than appears warranted by measured growth in poor countries one plausible cause is that richer households are less likely to participate in surveys but growth in the national accounts is also upward biased and consumption in the national accounts contains large and rapidly growing items that are not consumed by the poor and not included in surveys so it is possible for consumption of the poor to grow less rapidly than national consumption without any increase in measured inequality current statistical procedures in poor

low schooling for girls slower growth for all cross country evidence on the effect of gender inequality in education on economic development using cross country and panel regressions this article investigates how gender inequality in education affects long term economic growth such inequality is found to have an effect on economic growth that is robust to changes in specifications and controls for potential endogeneities the results suggest that gender inequality in education directly affects economic growth by lowering the average level of human capital in addition growth is indirectly affected through the impact of gender inequality on investment and population growth some 0 4 0 9 percentage points of differences in annual per capita growth rates between east asia and sub saharan africa south asia and the middle east can be accounted for by differences in gender gaps in education between these regions

relative income effects on subjective well being in the cross section abstract recent work suggests that a person s subjective well being swb depends to a large degree on relative income focusing on the underlying identification this paper makes four contributions to this literature it describes the aggregation problem with past studies implements an estimation strategy to overcome this problem finds micro level evidence in support of the hypothesis that relative income does matter in individual assessments of swb and uses cross section estimates to replicate the aggregate time series the evidence further indicates that relative income effects may be smaller at low income levels the results are obtained from ordered probit techniques and the general social survey gss

the developing world s bulging but vulnerable middle class summary western notions of the middle class are of little obvious relevance to developing countries instead the middle class is identified here as those living above the median poverty line of developing countries even if still poor by rich country standards over 1990 2005 economic growth and global distributional shifts allowed an extra 1 2 billion people to join the developing world s middle class four fifths came from asia and half from china many of those in this new middle class remain fairly close to poverty only 100 million of the 1 2 billion would not be considered poor in any developing county economic growth typically came with an expanding middle class

is more always better a survey on positional concerns abstract we use survey data to provide some empirical information about concerns regarding relative standing respondents chose between a world where they have more of a good than others and one where everyone s endowment of the good is higher but the respondent has less than others questions asked about education attractiveness and intelligence for one s child and oneself income vacation time approval and disapproval from a supervisor and papers to write half of the respondents preferred to have 50 less real income but high relative income concerns about position were strongest for attractiveness and supervisor s praise and weakest for vacation time

dollar a day revisited the article presents the first major update of the international 1 a day poverty line proposed in world development report 1990 poverty for measuring absolute poverty by the standards of the world s poorest countries in a new and more representative data set of national poverty lines a marked economic gradient emerges only when consumption per person is above about 2 00 a day at 2005 purchasing power parity below this the average poverty line is 1 25 which is proposed as the new international poverty line the article tests the robustness of this line to alternative estimation methods and explains how it differs from the old 1 a day line

why growth is not enough household poverty dynamics in northeast gujarat india despite high growth rates in gujarat exceeding 9 per cent per year over the decade of the 1990s poverty in 36 villages located in the northeastern part of this state has changed hardly at all in these villages 9 5 per cent of households escaped from poverty over the past 25 years but 6 3 per cent of households became poor at the same time escape and descent are not symmetric different reasons account for escaping poverty than those for declining into poverty growth alone is hardly sufficient to achieve poverty reduction on any significant scale public policies will be needed to address directly the separate causes for descent into poverty

production technology elasticity of substitution and technical efficiency of the handloom textile industry of bangladesh a number of translog and cobb douglas frontier production models were estimated for the bangladesh handloom textile industry to investigate its production technology and technical efficiency in production it was found that the technical efficiency of the industry in producing cloth was only 41 it was concluded that the industry might improve its technical efficiency by increasing its male female labour ratio and yarn capital ratio and decreasing its hired family labour ratio and labour capital ratio the production technology of the industry was found to be characterized by a linearly homogeneous cobb douglas function the elasticity of substitution between labour and capital for the industry was found to be unity

the efficiency of museums a stochastic frontier production function approach this article examines the technical efficiency of museums based upon data derived from a questionnaire survey of south west england a stochastic frontier production function is estimated with output measured in terms of visitor numbers the cobb douglas function is shown to be the best representation of the production function average levels of efficiency are estimated to be fairly low at 45 5 with wide variations across museums the results indicate that high levels of public funding and voluntary activity have a significantly negative impact on technical efficiency it is argued that further research is needed to develop more sophisticated measures of the output of cultural industries and understand the economic importance of volunteers

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