access to markets and rural poverty evidence from household consumption in china abstract this paper presents evidence on the effects of access to domestic and international markets on per capita consumption of households using data from rural china the econometric analysis uses alternative identification schemes to address the potential endogeneity of access to markets we use straight line distances to coastline and navigable river along with the topography of the intervening counties as sources of exogeneous variations we also use identification through heteroskedasticity which does not rely on standard exclusion restrictions the results from alternative identification schemes show that better access to both domestic and international markets has positive effects on per capita consumption the domestic market effect is significantly larger in magnitude and there is complementarity between the access to domestic and international markets

does microfinance change informal lending in village economies evidence from bangladesh this paper examines how availability of microfinance influences households borrowing from informal sources in village economies it uses a unique household level panel data set which spans more than two decades 1987 2008 from rural bangladesh we find that households access to microfinance reduces the incidence of borrowing from informal sources but not the amount of borrowing we find that less poor households benefit more in terms of reducing their reliance on informal borrowing and that the benefit accrues over time we also find that having access to microfinance increases women s informal borrowing for small consumption usage without facilitating access to new business opportunities

the microfinance promise in the past decade microfinance programs have demonstrated that it is possible to lend to low income households while maintaining high repayment rates even without requiring collateral the programs promise a revolution in approaches to alleviating poverty and spreading financial services and millions of poor households are served globally a growing body of economic theory demonstrates how new contractual forms offer a key to microfinance success particularly the use of group lending contracts with joint liability for the most part however high repayment rates have not translated into profits and studies of impacts on poverty yield a mixed picture in describing emerging tensions the paper highlights the diversity of innovative mechanisms beyond group lending contracts the measurement of financial sustainability the estimation of economic and social impacts the costs and benefits of subsidization and the potential to reduce poverty through savings programs rather than just credit the promise of microfinance has pushed far ahead of the evidence and an agenda is put forward for addressing critical empirical gaps and sharpening the terms of policy discussion

introduction imperfect information and rural credit markets puzzles and policy perspectives rural credit markets have been at the center of policy intervention in developing countries over the past forty years many governments supported by multilateral and bilateral aid agencies have devoted considerable resources to supplying cheap credit to farmers in a myriad of institutional settings the results of many of these interventions have been disappointing and one explanation for this must be that they were based on an inadequate understanding of the workings of rural credit markets the articles in this symposium issue are devoted to empirical and theoretical investigations of rural credit markets in the framework of the imperfect information paradigm the authors show how this framework is useful not only in explaining puzzling features of these markets but also in providing a policy perspective to assess the successes and failures of specific interventions

the computation of world income distribution there is a growing perception of the international economy as an interdependent system the un general assembly s 1974 75 declaration on principles and programs for a change in the international economic order assumes that the welfare of peasants workers businessmen civil servants and political elites in less developed countries ldcs are linked to decisions made by economic policymakers in the industrialized nations many people in ldcs especially elites compare their material levels of living with those of rich countries accordingly there is merit to examining global income distribution because scholars do not have a good technique for aggregating country income distributions into a world income distribution they rarely analyze this distribution this article presents a method of calculating global distribution given a set of national distributions as a sidelight to their work on purchasing power parity kravis heston and summers calculate world 145 nonsocialist countries income distribution but by nations not by households or individuals they assume that each individual receives his gnp per capita table 1

an empirical investigation of rationing constraints in rural credit markets in india abstract the literature on rural credit markets has generally assumed that households are rationed in their access to subsidized formal credit the validity of this assumption depends on the level of effective demand for formal credit in turn a function of the demand for credit and its availability from informal sources this paper estimates the demand and the sector specific costs of credit and hence the extent of formal sector rationing through an analysis of household participation in both the formal and the informal credit sectors the results show that the extent of rationing is considerably less than what is conventionally assumed

microfinance literature a sustainability level perspective survey abstract since the early microcredit programs up to the present microfinance has grown exponentially as it has the academic interest on it as a research subject considering that this sector has impact in terms of sustainability any research in the field requires an analysis with wide criteria which should include the economic environmental social and governance dimensions eesg as well as their interrelationships the objectives of this survey are to investigate the contributions of microfinance sectoral scholarly research to sustainability through a systematic literature review using content analysis method contextualizing the scientific production and studying its terminology according to the eesg criteria and under global reporting initiative framework and finally to identify research gaps and to propose future research paths

fuel prices and new vehicle fuel economy comparing the united states and western europe abstract several recent papers have documented an effect of fuel prices on new vehicle fuel economy in the united states this paper estimates the effect of fuel prices on average new vehicle fuel economy for the eight largest european markets the analysis spans the years 2002 2007 and uses detailed vehicle registration and specification data to control for policies consumer preferences and other potentially confounding factors we find fuel prices to have a statistically significant effect on average new vehicle fuel economy in europe the effect estimated for europe is much smaller than comparable estimates for the united states

the quantity and quality of life and the evolution of world inequality gdp per capita is usually used to proxy for the quality of life of individuals living in different countries welfare is also affected by quantity of life however as represented by longevity this paper incorporates longevity into an overall assessment of the evolution of cross country inequality and shows that it is quantitatively important the absence of reduction in cross country inequality up to the 1990s documented in previous work is in stark contrast to the reduction in inequality after incorporating gains in longevity throughout the post world war ii period health contributed to reduce significantly welfare inequality across countries this paper derives valuation formulas for infra marginal changes in longevity and computes a full growth rate that incorporates the gains in health experienced by 96 countries for the period between 1960 and 2000 incorporating longevity gains changes traditional results countries starting with lower income tended to grow faster than countries starting with higher income we estimate an average yearly growth in full income of 4 1 percent for the poorest 50 percent of countries in 1960 of which 1 7 percentage points are due to health as opposed to a growth of 2 6 percent for the richest 50 percent of countries of which only 0 4 percentage points are due to health additionally we decompose changes in life expectancy into changes attributable to 13 broad groups of causes of death and three age groups we show that mortality from infectious respiratory and digestive diseases congenital perinatal and ill defined conditions mostly concentrated before age 20 and between ages 20 and 50 is responsible for most of the reduction in life expectancy inequality at the same time the recent effect of aids together with reductions in mortality after age 50 due to nervous system senses organs heart and circulatory diseases contributed to increase health inequality across countries

symbiosis vs crowding out the interaction of formal and informal credit markets in developing countries abstract it is a common observation in many developing countries that enterprises are active borrowers in both formal and informal credit markets we propose a model in which the formal sector s superior ability in deposit mobilization is traded off against the informational advantage that lenders in the informal sector enjoy the formal sector can screen borrowers by providing only partial financing for projects thereby forcing borrowers to resort to the informal sector for the remainder of the loan we use the model to predict how the market structure responds to changes in the environment and we consider the policy implications of various forms of government intervention

economic growth population theory and physiology the bearing of long term processes on the this lecture sketches a theory of the secular decline in morbidity and mortality that takes account of changes induced in physiological functioning since 1700 the synergism between technological and physiological improvements has produced a form of human evolution biological though not genetic rapid culturally transmitted and not necessarily stable which is still ongoing in both oecd and developing countries thermodynamic and physiological aspects of economic growth are defined and their impact on growth rates is assessed implications of this theory for population forecasting measurement of national income demand for leisure pension policies and demand for health care are considered excerpt

inequality in sub saharan africa new data and new insights from anthropometric estimates reliable information on inequality within countries is highly scarce especially for less developed countries ldcs using anthropometric measures we extend the inequality database for sub saharan africa to no less than 28 countries over six five year periods from 1950 to 1980 and to some 200 regions within those countries in this process we also test in depth the validity of objections against the derivation of inequality measures from height data in a second step we test the determinants of inequality within and between the 200 regions under study our set of explanatory variables includes protein supply cash cropping industrial structure mineral resources distance to the countries capital urbanization education population density and ethnic fractionalization we find that monoculture cash cropping increases inequality whereas diversified cash cropping has the opposite effect

microfinance and moneylender interest rate evidence from bangladesh summary the linkage between the formal and informal credit markets in developing countries has largely been unexplored this paper addresses one important aspect of the linkage by empirically investigating the impact of the intervention of microfinance programs on the moneylender interest rates in northern bangladesh and finds that moneylender interest rates increase with microfinance program coverage higher microfinance program coverage increases moneylender interest rates in the villages in which more loans are invested in productive economic activities than consumption borrowers resort to moneylenders for additional funds probably because of inadequate supply unavailability of seasonal working capital from mfis and tight repayment schedules which in turn increase demand for moneylender loans

the gift of the dying the tragedy of aids and the welfare of future african generations this paper simulates the impact of the aids epidemic on future living standards in south africa i emphasize two competing effects on the one hand the epidemic is likely to have a detrimental impact on the human capital accumulation of orphaned children on the other hand widespread community infection lowers fertility both directly through a reduction in the willingness to engage in unprotected sexual activity and indirectly by increasing the scarcity of labor and the value of a woman s time i find that even with the most pessimistic assumptions concerning reductions in educational attainment the fertility effect dominates the aids epidemic on net enhances the future per capita consumption possibilities of the south african economy

exact consumer s surplus and deadweight loss consumer s surplus is a widely used tool in applied welfare economics both economic theorists and cost benefit analysis often use consumer s surplus despite its somewhat dubious reputation the basic idea is to evaluate the value to a consumer or his willingness to pay for a change in price of a good from say pricep to pricep because price changes affect consumer welfare an evaluation of this effect is often a key input to public policy decisions yet consumer s surplus is probably the most controversial of widely used economic concepts both paul samuelson and ian little conclude that the economics profession would be better off without it it is my feeling of the situation that substantial agreement exists on the correct quantities to be measured the amount the consumer would pay or would need to be paid to be just as well off after the price change as he was before the price change the quantities correspond to john hicks compensating variation measures an alternative measure which takes ex post price change utility as the basis of comparison is hicks equivalent variation the controversy arises in the measurement of these quantities the usual measurement procedure is to use the area to the left of the marshallian market demand curve between two price levels jules dupuit originated this measure of welfare change and alfred marshall and hicks derived appropriate conditions for its use the primary condition for the area to the left of the demand curve to correspond to the compensating variation is to have constant marginal utility of income marshall gave this condition and if it holds the same quantity will be derived as the area to the left of the compensated hicksian demand curve this area to the left of the compensated demand curve is exactly what the compensating variation and equivalent variation measure thus the constant marginal utility of income is a sufficient condition for marshallian consumer s surplus to be equal to hicks consumer s surplus in this case arnold harberger s plea to use the welfare triangle as one half times the product of the price change times the quantity change to measure deadweight loss corresponds to the correct theoretical amount of welfare change in a recent paper robert willig derives bounds for the percentage difference between the correct measure of either the compensating or equivalent variation and the marshallian measure derived form the market demand curve his bounds which depend on the income elasticity of demand for the single good in the region of price change being considered as well as the proportion of the consumer s income spent on the good demonstrate that the marshallian consumer s surplus is often a good approximation to hicks consumer s surplus the fact that the proportion of the consumer s income spent matters as well as the income elasticity was first pointed out by harold hotelling willig contends that the approximation error will be less than the errors involved in estimating the demand curve thus he hopes to remove the need for apology that applied economists often need to give to theorists who remark on the inappropriateness of using marshallian consumer s surplus to measure welfare change however in this paper i show that for the case primarily considered by willig of a single price change which is also the situation in which consumer s surplus is often used in applied work no approximation is necessary professor of economics massachusetts institute of technology and research associate national bureau of economic research i would like to thank peter diamond erwin diewert daniel mcfadden robert merton robert solow hal varian joel yellin and the referees for help and comments research support from the national science foundation is acknowledged the reason that we still have two rather than one of samuelson s six measures of consumer s surplus arises from an index number problem of the correct basis for the welfare comparison i will give both measures but plan to concentrate on the compensating variation

a theory of interactions between mfis and informal lenders abstract we provide a theoretical analysis of effects of entry of a microfinance institution mfi into an informal credit market which is segmented whereby informal lenders derive some market power owing to privileged information concerning borrower specific default risks relative to informal lenders the mfi has a cost advantage and an informational disadvantage regarding borrower risk borrowers differ along another dimension landholding which is observable to all lenders mfi entry is shown to induce selection effects across risk and landownership dimensions in shifts of borrowers from informal lenders to the mfi which could raise informal interest rates as observed in many ldcs the model is consistent with evidence from bangladesh and west bengal in contrast to hypotheses based on cream skimming scale diseconomy inducing collusion facilitating or crowding in effects of mfis on informal credit the model implies that mfi entry is pareto improving for borrowers irrespective of effects on informal interest rates

microfinance spillovers a model of competition in informal credit markets with an application to indian villages despite widespread interest in the development of microfinance spillover effects on the non using population and redistributive issues remain largely unexplored i study a competition game between microfinance institutions mfis offering joint liability loans and moneylenders offering individual loans in presence of adverse selection i show that one unintended consequence of the entry of a microfinance sector in local credit markets can be to trigger an increase in the equilibrium informal interest rate because mfis tend to attract a disproportionately safe share of the borrower pool away from incumbent moneylenders the existence of such composition externality depends crucially on the size of the microfinance sector and the risk composition of the borrower pool the model predicts a non linearly increasing relationship between informal interest rates and mfis capacity in relatively safe credit markets and no relationship in risky villages i show evidence supporting these predictions using a first hand panel database that records all credit transactions over 8 years for a sample of about 1000 households living in indian villages with extensive space and time variation in the size of their microfinance sector

early mortality declines at the dawn of modern growth we explore the hypothesis that demographic changes which began in the seventeenth and eighteenth centuries are at the root of the acceleration in growth rates at the dawn of the modern age during this period life tables for geneva and venice show a decline in adult mortality french marriage registers reveal an important increase in literacy historians measure an acceleration of economic growth we develop an endogenous growth model with a realistic survival law in which rising longevity increases individual incentives to invest in education and fosters growth we quantitatively estimate that the observed improvements in adult mortality account for 70 of the growth acceleration in the pre industrial age

wealthier is healthier we estimate the effect of income on health using cross country timeseries data on health infant and child mortality and life expectancy and income per capita we use instrumental variables estimates using exogenous determinants of income growth to identify the pure income effect on health isolated from reverse causation or incidental association the long run income elasticity of infant and child mortality in developing countries lies between 0 2 and 0 4 using these estimates we calculate that over a half a million child deaths in the developing world in 1990 alone can be attributed to the poor economic performance in the 1980s

economic development and the escape from high mortality summary this paper studies the characteristic features of the escape from high mortality as recorded from the historical experience of northwestern europe and from the current experience of less developed countries the paper documents stylized facts of mortality change and measures the contribution of economic development represented by income per capita to the mortality decline during the second half of the 20th century the paper argues that improvements in economic conditions since the 18th century are an important factor behind the decline in death rates in developed countries and in the subsequent reduction of death rates in less developed countries we show that economic development lowers mortality through differential effects in infectious disease mortality and that quantitatively income growth is able to account for between one third and one half of the recent mortality decline

an indirect utility model of car ownership and private car use abstract in this paper a model is developed for the simultaneous determination of private car ownership and private car use measured as the annual number of kilometers this model is a micro economic utility model in which the fixed and variable car costs enter through the budget restriction this allows us to do micro simulations of increasing those costs which is a policy issue in the netherlands it turns out that in this model both fixed and variable car costs are effective measures for reducing traffic growth the former working primarily through decreasing car ownership levels the latter having a more direct effect on car use

sewers diffusion and the decline of mortality the case of paris 1880 1914 it is common to argue that water infrastructure innovations improve life expectancy yet the benefits of clean water depend on a mechanism to dispose of waste water we draw on the historical experience of a large industrial city to estimate the impact of the spread of the sewer system using a longitudinal data set on mortality and rents for each of paris 80 neighborhoods we show that sanitation contributed several years to life expectancy these results point out the multiplicity of infrastructure needed to help decrease mortality

poverty and famines an essay on entitlement and deprivation this book focuses on the causes of starvation in general and famines in particular the traditional analysis of famines is shown to be fundamentally defective and the author develops an alternative analysis

a little at a time the use of regularly scheduled repayments in microfinance programs abstract informal lenders appear to be thriving even in regions where microfinance institutions mfis such as the grameen bank have established lending programs we suggest that an explanation for this well documented observation lies in the ubiquitous use of regularly scheduled repayments by mfis borrowers are typically required to repay their loans in tightly structured installments beginning soon after loan disbursement this little remarked aspect of the repayment schedule is usually explained as inculcating fiscal discipline among borrowers we argue that an alternative rationale for this loan repayment structure lies in the difficulty of monitoring borrowers actions the potential for moral hazard leads mfis to use innovative mechanisms such as regularly scheduled repayments which indirectly coopt the better informed informal lenders conversely this installment repayment structure allows informal lenders to survive further we show that this linkage can not only expand the volume of informal lending but may also raise the interest rate in the informal sector

the determinants of moneylender interest rates evidence from rural india this study examines the determinants of moneylender interest rates in rural india in the context of two major developments of the 1960s a the incidence of agricultural technical change in the process popularly denoted by the term green revolution and b the spread of government sponsored subsidised credit through rural banks and co operative credit agencies it finds that farmers residing in areas characterised by the use of green revolution technology face lower moneylender interest rates it also finds evidence of the reduction of moneylender monopoly power as a result of increased competition from formal lending agencies it concludes that informal rural credit markets are sensitive mechanisms which respond to environmental as well as borrower characteristics

mortality decline human capital investment and economic growth abstract we examine the role of increased life expectancy in raising human capital investment during the process of economic growth we develop a continuous time overlapping generations model in which individuals make optimal schooling investment choices in the face of a constant probability of death we present analytic results followed by results from a calibrated version of the model using realistic estimates of the return to schooling mortality decline produces economically significant increases in schooling and consumption allowing schooling to vary endogenously produces a much larger response of consumption and capital to mortality decline than is observed when schooling is held fixed

human development in poor countries on the role of private incomes and public services development is often taken to mean rising incomes discussions of the goals of development now often emphasize the reduction of poverty rather than raising average incomes per se the role of social services particularly basic health and education has also received greater emphasis in the 1980s viewed mainly as instruments for raising the incomes of the poor but in all these approaches income growth of one sort or another is what development is all about a rather different view of the meaning of development has recently found expression in the 1990 human development report hrd produced by the united nations development programme a conceptual underpinning for this approach can be found in the work of amartya sen the essence of this view is that human development what people can actually do and be is the overriding purpose of economic development underdevelopment is viewed as the lack of certain basic capabilities rather than lack of income per se we do not aim here to advocate one of these approaches over the other but rather to explore their implications for development policy for instance what does the human development approach imply about the role of economic growth and in particular about reducing income poverty should development priorities shift toward the provision of public services in poor countries even if such a shift is at the expense of income growth

from malthus to modern growth can epidemics explain the three regimes we model demographic and economic long run development in a setting where mortality is endogenous and subject to epidemic shocks the model replicates the full transition from malthusian stagnation to modern growth consistent with the historical facts the economy also passes an intermediate post malthusian phase where growth rates of both population and per capita income increase simultaneously as mortality rates fall and become less volatile the escape from the malthusian trap is the result of a series of mild epidemic shocks making it inevitable at some stage but its timing random calibrations show that it can differ by thousands of generations absent differences in exogenous parameters

analysing gasoline demand elasticities a survey this paper is a survey of studies on gasoline demand although there are very many dxerent studies in this eld which sometimes appear to arrive at contradictory results we find that with proper stratification of studies by model and data type much of the contict turns to consensus in this survey we classtfy studies by data type and by ten d erent categories of model and with the exception of estimates on seasonal data which tend to be unstable and of certain inappropriate model formulations we find a fair degree of agreement concerning average short run and even long run income and price elasticities

imperfect information screening and the costs of informal lending a study of a rural credit market in pakistan many governments have perceived the rural moneylender as usurious this article takes a first step toward directly testing the validity of this view in a study of services costs and charges of fourteen informal market moneylenders and their clients in chambar pakistan the article examines whether the high implicit interest rates charged reflect the actual costs of operating in that market estimates of the resource costs incurred by informal lenders for screening pursuing delinquent loans overhead and cost of capital including unrecoverable loans suggest that lenders charges are equal to their average cost of lending but exceed their marginal cost this finding is consistent with the view that the informal credit market is characterized by excess capacity and monopolistic competition in the presence of imperfect information

the taxation of drivers and the choice of car fuel type in this paper the choice of the car fuel type is studied in the dutch situation three types are important gasoline diesel and lpg with 80 of the cars using gasoline incentives for using diesel or lpg are provided by the tax system that implies higher fixed cost but lower variable cost for users of these fuel types we start by studying fuel type choice on the basis of a logit model and move on to estimate demand functions for kilometres driven for social purposes while correcting for the possible selectivity bias we find that diesel and lpg are in general regarded as inferior alternatives but that monetary incentives are sufficiently strong to overcome this hurdle for drivers with a large demand for kilometres we also find that there are significant effects of the lower variable cost for diesel and lpg drivers on their demand for kilometres the conclusions are confirmed by estimation of a structural model in which fuel type choice and demand for kilometres are consistently explained on the basis of one set of preferences and unobserved heterogeneity is taken into account

famines and economics famines have happened with and without crop failures or wars but they invariably entail a collapse in the command over food of vulnerable subgroups within a society whether through loss of endowment or a contraction in the amount of food that can be acquired from given endowments thus economic analysis can help understand famines viewed as tragic aperiodic magnifications of normal market and governmental failures recent literature in economics and other fields has reflected this change in the conceptualization of famines and it has come with policy implications for famine relieve and prevention

micro credit initiatives for equitable and sustainable development who pays abstract there is a growing acknowledgement that micro credit programs have potential for equitable and sustainable development however my anthropological research on the micro credit program of the grameen bank shows that bank workers are expected to increase disbursement of loans among their members and press for high recovery rates to earn profit necessary for economic viability of the institution to ensure timely repayment in the loan centers bank workers and borrowing peers inflict an intense pressure on women clients in the study community many borrowers maintain their regular payment schedules through a process of loan recycling that considerably increases the debt liability on the individual households increases tension and frustration among household members produces new forms of dominance over women and increases violence in society

moneylenders and bankers price increasing subsidies in a monopolistically competitive market abstract in many areas of the world a significant part of the cost of obtaining a good or service is the cost of enforcing the contracts entailed in its provision we present models of markets with endogenous enforcement costs motivated by studies of rural credit markets we show that subsidies may have perverse effects under monopolistic competition increasing prices or inducing exit higher prices interest rates result from the loss of scale economies or from negative externalities among suppliers the models are consistent with the puzzling evidence that infusions of government subsidized formal credit have not improved the terms offered by moneylenders

formal informal sector interaction in rural credit markets abstract the majority of small cultivators in the less developed countries are not regarded as credit worthy by the formal sector financial institutions and are forced to borrow from the moneylenders in the informal credit market this paper shows that when such borrowers differ in their likelihood of default and the moneylenders are asymmetrically informed about the client specific degree of risk the policy of providing cheap credit through the formal sector can generate adverse composition effects which worsen the terms of credit and the availability of loans in the informal sector

the comparison of multi dimensioned distributions of economic status the literature on inequality measurement has been largely concerned with single dimensioned indicators this paper explores some of the issues which arise when there are several dimensions to inequality and these are not readily reduced to a single index concentrating particularly on the two dimensioned case we make use of results on multi variate stochastic dominance in portfolio theory extending these and applying them to the measurement of inequality the use of the dominance conditions is illustrated by an application to the international distribution of income and life expectancy

a general index of technical change this paper outlines a procedure for estimating a general index of technical change within the context of a quite general production technology specifically when panel data are available for firms in an industry time specific dummies can be combined in a nonlinear estimation procedure to yield a general index of technical change that may be both nonneutral and scale augmenting this approach offers numerous advantages over the traditional time trend representation of technical change for example the general index can serve as the basis for analysis of the determinants of technical change results for a sample of 30 electric utilities over the period 1951 78 show that the productivity decline of the 1970s can be attributed primarily to sulphur oxide restrictions and secularly declining capacity utilization due to rapidly increasing peak load demands

the impact of tax reform on new car purchases in ireland we examine the impact of recent tax reforms in ireland on private car transport and its greenhouse gas emissions a carbon tax was introduced on fuels and purchase vehicle registration and ownership motor taxes were switched from engine size to potential emissions we use a demographic model of the car stock by age size and fuel and a car purchase model that reflects the heterogeneous distribution of mileage and usage costs across various engine sizes the model shows a dramatic shift from petrol to diesel cars particularly for large engines the same pattern is observed in the latest data on car sales this has a substantial impact on tax revenue as car owners shift to the lower tax rates the tax burden has shifted from car ownership to car use and that the overall tax burden on private car transport falls as diesel engines are more fuel efficient than petrol engines carbon dioxide emissions fall modestly or if we consider the rebound effect of travel costs on mileage minimally from the perspective of the revenue the costs per tonne of carbon dioxide avoided are very high

the long run effect of aid on health evidence from panel cointegration analysis abstractalthough a major objective of aid donors is to improve health outcomes in recipient countries there is relatively little research on whether aid to the health sector leads to improved heal

interactions between institutional and informal credit agencies in rural india in an attempt to expand rural credit and displace the village moneylender india created a system of rural cooperatives in the 1950s and expanded branch banking into rural areas in the 1970s this article examines how these measures affected the rural market it begins with the question of how large the expansion of institutional credit has been and the extent to which it has dislodged the village and nonresident moneylenders a detailed comparison of three major surveys of the indian rural credit market suggests that in various guises the moneylender is still a major source of loans the article also examines the weak evidence on intermediation between the formal and informal sectors a formal model of the interaction between the informal moneylender and institutional lender is constructed under a variety of assumptions about the exclusivity of loan contracts and the competitive structure of the informal sector the conclusions are drawn together in the form of five proposals for public policy

inequality among world citizens 1820 1992 this paper investigates the distribution of well being among world citizens during the last two centuries the estimates show that inequality of world distribution of income worsened from the beginning of the 19th century to world war ii and after that seems to have stabilized or to have grown more slowly in the early 19th century most inequality was due to differences within countries later it was due to differences between countries inequality in longevity also increased during the 19th century but then was reversed in the second half of the 20th century perhaps mitigating the failure of income inequality to improve in the last decades jel d31 f0 n0 o0
