optimal dynamic pricing for perishable assets with nonhomogeneous demand we consider a dynamic pricing model for selling a given stock of a perishable product over a finite time horizon customers whose reservation price distribution changes over time arrive according to a nonhomogeneous poisson process we show that at any given time the optimal price decreases with inventory we also identify a sufficient condition under which the optimal price decreases over time for a given inventory level this sufficient condition requires that the willingness of a customer to pay a premium for the product does not increase over time in addition to shedding managerial insight these structural properties enable efficient computation of the optimal policy numerical studies are conducted to show the revenue impact of dynamic price policies price changes are set to compensate for statistical fluctuations of demand and to respond to shifts of the reservation price for the former our examples show that using optimal dynamic optimal policies achieves 2 4 7 3 revenue improvement over the optimal single price policy for the latter the revenue increase can be as high as 100 these results explain why yield management has become so essential to fashion retailing and travel service industries

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

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

pricing and capacity rationing for rentals with uncertain durations we consider a rental firm with two types of customers contract customers pay fixed prenegotiated rental fees and expect a high quality of service walk in customers have no contractual relations with the firm and are shopping for price given multiple contract and walk in classes the rental firm has to decide when to offer service to contract customers and what fees to charge walk in customers for service we formulate this rental management problem as a problem in stochastic control and characterize optimal policies for managing contract and walk in customers we also consider static myopic controls that are simpler to implement and we analytically establish conditions under which these policies perform optimally complementary numerical tests provide a sense of the range of systems for which myopic policies are effective

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

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

markup pricing in mergers and acquisitions this paper studies the relation between the premiums in takeover bids involving exchange listed target firms from 1975 91 and the pre announcement stock price runups the evidence shows that the pre bid runup and the postannouncement increase in the target s stock price the markup are generally uncorrelated with little substitution between the runup and the markup the runup is an added cost to the bidder this finding has important implications for assessing the costs of insider trading it also raises interesting questions about the role of information from public capital markets in private takeover negotiations

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

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

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

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

capacity management in rental businesses with two customer bases we consider the allocation of capacity in a system in which rental equipment is accessed by two classes of customers we formulate the problem as a continuous time analogue of the one shot allocation problems found in the more traditional literature on revenue management and we analyze a queueing control model that approximates its dynamics our investigation yields three sets of results first we use dynamic programming to characterize properties of optimal capacity allocation policies we identify conditions under which complete sharing in which both classes of customers have unlimited access to the rental fleet is optimal next we develop a computationally efficient aggregate threshold heuristic that is based on a fluid approximation of the original stochastic model we obtain closed form expressions for the heuristic s control parameters and show that the heuristic performs well in numerical experiments the closed form expressions also show that in the context of the fluid approximation revenues are concave and increasing in the fleet size finally we consider the effect of the ability to allocate capacity on optimal fleet size we show that the optimal fleet size under allocation policies may be lower the same as or higher than that under complete sharing as capacity costs increase allocation policies allow for larger relative fleet sizes numerical results show that even in cases in which dollar profits under complete sharing may be close to those under allocation policies the capacity reductions enabled by allocation schemes can help to lift profit margins significantly

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

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

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

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

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

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

does option provide more informative content than stock after regulation fair disclosure this article examines the impact of regulation fair disclosure reg fd which intends to eliminate selective disclosure to only a few privileged interested parties on the information embedded in the stock and option markets prior to tender offer announcements in the pre announcement period after reg fd the volume of public option information contains less information about subsequent stock price movements although the quantity of public information may be higher after reg fd the inferior quality of publicly available option information dominates the higher quantity thus the predictive power of option information decreases in the post rfd pre announcement period the volume of public option information is more informative than the volume of stock private information it indicates that although the quality of private stock information is superior to that of public option information the much lower quantity of stock information results in a lower predictive power of private stock information than t

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

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

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

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

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

on intraday risk premia this article presents a framework for analyzing the dynamic effects of anticipated large demand pressures on asset risk premia we show that large institutions who can time their entry into the market will trade either at the open or during periods of unusual demand pressures we show that if these institutions do enter later in the day they trade in the same direction as institutions which provide liquidity continuously institutions therefore appear to exhibit herding behavior we also explore how changing the uncertainty of demand pressures late in the day affects trading costs throughout the day most financial market investors do not continuously monitor intraday fluctuations in stock prices other activities e g outside employment often take precedence over following the stock market and there are limitations to processing information for example a reader of this page is likely to be unaware of current financial market prices in fact for many investors entry into financial markets occurs once a day or even less frequently given these institutional realities it is of interest to explore how asset markets react when it is known that a set of very large predictable demands will arrive during the afternoon does their arrival affect prices only when they arrive or throughout the day if the price impact is spread out then how do trading costs behave during the day if some traders have the flexibility to time their entry into the market when will they arrive during the day and how will their entry decisions affect asset risk premia if market participants anticipate that demands in the afternoon will be unusually volatile how does this affect the intertemporal behavior of prices and expected returns earlier in the day the primary focus of this article is the development of tractable methodologies that can address these issues

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

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

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

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

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

effects of system parameters on the optimal cost and policy in a class of multidimensional queueing control problems we consider a class of markov decision processes frequently employed to model queueing and inventory control problems for these problems we explore how changes in different system input parameter

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

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

pricing and design of differentiated services approximate analysis and structural insights we consider a model of a service system that delivers two nonsubstitutable services to a market of heterogenous users the first service is delivered subject to a guaranteed g processing rate and the second is a best effort be type service in which residual capacity not allocated to the guaranteed class isshared among be users users in turn are sensitive to both price and congestion related effects the service provider s objective is to optimally design the system so as to extract maximum revenues the design variables in this problem consist of a pair of static prices for the two services a policy that controls admission of g users into the system and the mechanism by which users are informed of the state of congestion in the system because these objectives are difficult to address using exact analysis we pursue approximations that are tractable and lead to structural insights specifically we first solve a deterministic relaxation of the original objective to obtain a fluid optimal solution that is subsequently evaluated and refined to account for stochastic fluctuations using diffusion limits we derive approximations that yield the following structural results 1 pricing rules derived from the deterministic analysis are almost optimal 2 the optimal operational regime for the system is close to heavy traffic and 3 real time congestion notification results in increased revenues numerical results illustrate the accuracy of the proposed approximations and validate the aforementioned structural insights

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

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

airline seat allocation with multiple nested fare classes this paper addresses the problem of determining optimal booking policies for multiple fare classes that share the same seating pool on one leg of an airline flight when seats are booked in a nested fashion and when lower fare classes book before higher ones we show that a fixed limit booking policy that maximizes expected revenue can be characterized by a simple set of conditions on the subdifferential of the expected revenue function these conditions are appropriate for either the discrete or continuous demand cases these conditions are further simplified to a set of conditions that relate the probability distributions of demand for the various fare classes to their respective fares the latter conditions are guaranteed to have a solution when the joint probability distribution of demand is continuous characterization of the problem as a series of monotone optimal stopping problems proves optimality of the fixed limit policy over all admissible policies a comparison is made of the optimal solutions

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

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

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

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

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

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
