externality and literacy a note abstract kaushik basu and james foster 1998 have opened up an interesting approach to the measurement of literacy in which the phenomenon of externality has an important role to play the externality these authors examine is what one may call a material externality and they demonstrate that reckoning such an externality in the measurement of literacy provides an instrumental justification for horizontal equity the present note elucidates this link through a specific formulation of the basu foster thesis it also suggests that apart from a material externality there is also a psychic externality to be considered the psychic externality runs in a direction somewhat orthogonal to that of the material externality postulated by basu and foster and it is shown that reckoning such an externality in the measurement of literacy provides an instrumental justification for being sensitive to levels of literacy attainment in comparisons of literacy improvements in a broad sense the note suggests

the environmental kuznets curve environmental protection policy and income distribution abstract the effect of economic growth on pollution emissions differs substantially among high income countries i address this issue by analyzing public environmental policy decisions individual heterogeneity relative income effect and the political framework in which policy decisions are taken determine the emergence of the downward sloping segment of the environmental kuznets curve ekc income inequality produces a gap between the country s ability to pay for environmental protection and a country s willingness to pay i test this result by using oecd data on public r d expenditure for environmental protection the conclusion is that contrary to the ek hypothesis moments of the income distribution function other than the mean may be important for the emergence of a virtuous path of sustainable growth in high income countries

a dynamic approach to the environmental kuznets curve hypothesis abstract the environmental kuznets curve ekc hypothesis states that pollution levels increase as a country develops but begin to decrease as rising incomes pass beyond a turning point in ekc analyses the relationship between environmental degradation and income is usually expressed as a quadratic function with the turning point occurring at a maximum pollution level other explanatory variables have been included in these models but income regularly has had the most significant effect on indicators of environmental quality one variable consistently omitted in these relationships is the price of energy this paper analyzes previous models to illustrate the importance of prices in these models and then includes prices in an econometric ekc framework testing energy income and co2 income relationships these long run price income models find that income is no longer the most relevant indicator of environmental quality or energy demand indeed we find no significant evidence for the existence of an ekc within the range of current incomes for energy in the presence of price and trade variables

economic growth and poverty reduction measurement issues using income and non income indicators summary this paper first reviews the debate on the definition of pro poor growth and argues that a relative definition has merits when defining the state of pro poor growth while an absolute definition is most suitable when analyzing the rate of pro poor growth the second contribution is to extend the pro poor growth toolbox to non income indicators the analysis applied to bolivia shows that this extension greatly improves our understanding of the distribution of change in non income indicators of the linkages between progress in income and non income dimensions of poverty and on the incidence of progress in non income outcomes along the income distribution

inequality and the impact of growth on poverty comparative evidence for sub saharan africa abstract this study explores the extent to which inequality affects the impact of income growth on the rates of poverty changes in sub saharan africa ssa compared to non ssa based on an unbalanced panel of 86 countries over 1977 2004 for all three measures of poverty headcount gap and squared gap the impact of gdp growth on poverty reduction is a decreasing function of initial inequality the impacts are similar in direction for ssa and non ssa so that within both regions there are considerable disparities in the responsiveness of poverty to income growth depending on inequality nevertheless the income growth elasticity is substantially less for ssa implying relatively small poverty reduction response to growth

dynamic inefficiency endogenous growth and ponzi games we show that in competitive endogenous growth models without externalities balanced growth equilibria are dynamically efficient with learning by doing externalities dynamic inefficiency may exist but due to the mix of capital rather than its scale these results are obtained independent of whether or not lifetimes are finite or generations overlap in olg models with externalities we show that ponzi games may be feasible even though equilibria are characterized by undersaving

troubling tradeoffs in the human development index the 20th human development report has introduced a new version of its famous human development index hdi the hdi aggregates country level attainments in life expectancy schooling and income per capita each year s rankings by the hdi are keenly watched in both rich and poor countries the main change in the 2010 hdi is that it relaxes its past assumption of perfect substitutability between its three components however most users will probably not realize that the new hdi has also greatly reduced its implicit weight on longevity in poor countries relative to rich ones a poor country experiencing falling life expectancy due to say a collapse in its health care system could still see its hdi improve with even a small rate of economic growth by contrast the new hdi s valuations of the gains from extra schooling seem unreasonably high many times greater than the economic returns to schooling these troubling tradeoffs could have been largely avoided using a different aggregation function for the hdi while still allowing imperfect substitution while some difficult value judgments are faced in constructing and assessing the hdi making its assumed tradeoffs more explicit would be a welcome step

social indicators and comparisons of living standards abstract construction of an international index of standards of living incorporating social indicators and economic output typically involves scaling and weighting procedures that lack welfare economic foundations revealed preference axioms can be used to make quality of life comparisons if we can estimate the representative household s production technology for the social indicators this method is applied to comparisons of gross domestic product gdp and life expectancy for 58 countries neither gdp rankings nor the rankings of the human development index hdi are consistent with the partial ordering of revealed preference a method of constructing a utility consistent index incorporating both consumption and life expectancy is suggested

poverty and public policy the problem of poverty is particularly acute in india with 14 of the world s population we have the misfortune of having almost twice as large a share of the world s poor indeed as i shall presently underline the question of poverty and its amelioration has been at the center of our concerns from the beginning of our planning efforts almost four decades ago little therefore can be said on it that some distinguished indian economist has not already said in some ways therefore to talk on the design of public policy for poverty to an indian audience is to carry coal to newcastle or as the old saying goes to teach your grandmother how to suck eggs nonetheless i hope to provide a fresh perspective by putting the problem into an explicit analytical framework that permits alternative policy designs to be sharply defined and contrasted i also intend to draw on international experience to put our efforts and problems into both historical and comparative perspectives

interrelationships between income health and the environment extending the environmental kuznets curve hypothesis abstract this paper examines the link between the health indicators and the environmental variables for a cross section of countries widely dispersed on the economic development spectrum while environment and income are seen to have an inverted u shaped relationship environmental kuznets curve ekc hypothesis it is also well established that environment and health are positively related our study focuses on the implications of this for the relationship between health and income in the early phases of income growth the gains in health and the losses in environmental quality could cancel each other out and this challenges the idea that as incomes increase health would always improve to empirically analyse these issues we estimate a two stage least squares model that focuses on the impact of income and the environment on health status with environment being an endogenous variable our results show that the environmental stress variable has a significant negative effect on health status at the same time gross national product gnp levels are shown to vary positively with health status variables we find that the health gains obtained through improved incomes can be negated to a significant extent if the indirect effect of income acting via the environment is ignored research findings in this regard would be a useful policy instrument towards maximising both the environmental and health gains that come with economic growth and development

demand inducement and the physician patient relationship the physician patient relationship is a paradigm for any expert client relationship the physician both diagnoses the patient s illness and recommends a treatment this dual role gives the physician incentive to recommend treatments whose costs outweigh their medical benefits these socially inefficient treatments correspond to the notion of physician induced demand the level of inducement chosen by the physician is shown to depend on the price and potential medical benefits of treatment and the relative diagnostic skills of physician and patient this model offers several testable hypotheses some of which are confirmed by related studies

children s environmental health education and economic development this article aims at investigating the interplay between environmental quality health and economic development in a unified olg framework human capital accumulation depends on the environment through its impact on children s health and workers productivity in turn environmental quality dynamics rely upon human capital that determines maintenance efforts this two way relationship generates a co evolution of human capital and environmental quality in the long run along the transition path the dynamic interactions between economic and environmental spheres allow for replicating two different trajectories some economies experiment an environmental kuznets curve while some others are caught into the environmental poverty trap

environmental kuznets curves real progress or passing the buck abstract recent research has examined the hypothesis of an environmental kuznets curve ekc the notion that environmental impact increases in the early stages of development followed by declines in the later stages these studies have focused on the relationship between per capita income and a variety of environmental indicators results imply that ekcs may exist for a number of cases however the measures of environmental impact used generally focus on production processes and reflect environmental impacts that are local in nature and for which abatement is relatively inexpensive in terms of monetary costs and or lifestyle changes significantly more consumption based measures such co2 emissions and municipal waste for which impacts are relatively easy to externalize or costly to control show no tendency to decline with increasing per capita income by considering consumption and trade patterns the author re examines the concept of the ekc and proposes the use of alternative consumption based measures of environmental impact the author speculates that what appear to be improvements in environmental quality may in reality be indicators of increased ability of consumers in wealthy nations to distance themselves from the environmental degradation associated with their consumption

political and economic inequality and the environment abstract this paper analyzes and tests the hypothesis that political and economic equality result in lower levels of environmental degradation based on formal statements of the argument put forward by boyce r 1994 ecological economics 11 169 178 i show that equality may or may not be necessary to minimize degradation under some plausible conditions greater inequality may even be conducive to lower degradation actual results depend primarily on the intersection between the distribution of preferences across groups and the institutional rules two cross national empirical tests tend to support the contention that distributional issues do not systematically explain variations in environmental quality the results reinforce the conclusion that assumptions about the structure of preferences and workings of social choice institutions ignore complex interactions which influence the relationship between degradation and equality

testing the environmental kuznets curve hypothesis across the u s evidence from panel mean group estimators abstract it is widely believed that greenhouse gases contribute to a warmer climate since global warming is a serious threat and greenhouse gas emissions are one of the main causes of it analyzing the effects of economic development on environment have great importance in this study the validity of the environmental kuznets curve ekc hypothesis is tested for the 50 u s states during the 1960 2010 period using recent panel data estimators that take cross sectional dependence and slope heterogeneity into account accordingly the cross sectional dependence and slope heterogeneity robust estimators augmented mean group amg and common correlated effects mean group estimator ccemg provide mixed results the amg estimator strongly validates the ekc hypothesis asserting that the ekc holds in 30 of the 50 states with turning points for income per capita lie between 1292 and 48597 on the contrary the ccemg estimator provides only weak evidence on the ekc hypothesis and the ekc holds only in 10 states with turning points between 2457 and 14603

testing the food first hypothesis a cross national study of dependency sectoral growth and food intake in less developed countries abstract previous cross national studies on dependency and economic growth in less developed countries ldcs seldom compare the impacts of different kinds of dependency their focus on economic growth also overlooks the fact that growth per se does not necessarily benefit the masses an alternative measure of the absolute living standard of the masses i e food intake is examined in this paper this study analyzes data from 73 ldcs after comparing the effects of manufacturing growth and cereal production growth on food intake this study supports the food first hypothesis derived from lappe and collins 1977 work since it demonstrates that in most ldcs even in middle income ldcs cereal production has a much stronger effect on food intake than does manufacturing growth

on measuring aggregate social efficiency abstract cross country comparisons of social indicators controlling for income and or social spending have been widely used to measure and explain social efficiency analogously to technical efficiency in production the article argues that these methods are clouded in ambiguities about what is being measured standard methods of measuring technical efficiency require assumptions that are unlikely to hold for social indicators in the context of a simple parametric model of life expectancy conditions are identified under which there will be a systematic pattern of bias in estimates of efficient public health spending

markets for medical care and medical education an integrated long run structural approach this paper investigates the relationship between the market for medical care and the market for medical education within a standard supply and demand framework the capacity of medical schools is considered as an endogenous element within a complete structural system of the market for physicians services the parameters of the model are estimated using data from the postwar period the estimated system is then simulated both to compare it to alternative time series forecasting approaches and to examine the nature of earnings cycles in medicine the results of this exercise support the applicability of traditional economics to this sector of the economy

a theoretical basis for the environmental kuznets curve abstract this paper attempts to explain the environmental kuznets curve ekc or inverted u shaped relationship between income and environmental degradation in the framework of endogenous growth model considering a closed economy one part of capital is used for commodity production which generates pollution that degrades existing environment and the remaining part is used for abating pollution i e upgrading environment sufficient abatement activity improves restores environmental quality a sufficient abatement activity associated with commodity production could only lead optimally towards steady state the ratio of allocation of capital between two sectors production and abatement is fixed along the optimal path but it varies along the non optimal path that exists in the off steady state in the economy allocation of capital for abatement activity varies over time thus a change from insufficient to sufficient allocation of capital i e investment for abatement activity is the basis for an inverted u shaped relationship between environmental quality and economic growth

the economics of medicare equilibrium within the medical community this paper partially fills a theoretical void by developing an integrated model of the various branches of the medical community a consistent and general framework is adopted to analyze equilibrium within the market for medical services under a stylized form of socialized medicine without invoking demand shifting the optimization problem faced by each agent is specified and the equilibrium is defined the effect of various parameter changes on the market for medical services is analyzed the predictions are not contradicted by the stylized facts

the market for medical services and physicians an application of hedonic price theory without disputing the importance of the special characteristics found in the market for medical services it is argued in this paper that the standard economic model of maximizing behaviour rather than an idiosyncratic theoretical formulation unique to the medical profession is well suited to this market this conclusion is based on analysis in which the technique of equalizing differences is used to define a competitive equilibrium that provides the possibility of both price and non price competition the maximizing model developed provides an alternative theoretical explanation of the limit placed on supplier induced demand to that offered by the target income model of physician behaviour or that offered by the arguments based on medical ethics le marche des soins et des medecins une application de la theorie des prix hedoniques sans remettre en question l importance des caracteristiques particulieres du march6 des soins l auteur suggere que le modele traditionnel de comportement de maximisation est applicable a ce march6 et un substitut preferable aux formulations theoriques specifiquements dessinees pour la profession medicale l auteur derive cette conclusion d une analyse dans laquelle la technique des diff6rences egalisantes est utilisee pour definir un equilibre concurrentiel qui accommode la concurrence par les prix mais aussi par d autres moyens le modele de comportement de maximisation qui est developpe fournit une explication th6orique de rechange pour la limite placee sur la demande engendree par le producteur les autres explications ont ete fournies par des modeles de comportement du medecin tentant de se donner acces a un revenu cible ou encore par des explications fondees sur l ethique medicale the market for medical care is distinct from that for other commodities since medical services are often non transferable once purchased kessel 1958 pauly 1978 and consumers frequently find it difficult to evaluate medical services evans 1974 these characteristics of the medical market and the observation that physician density and both physician fees and services are positively associated have encouraged the assertion that physicians control demand sloan and feldman 1978 although research assistance by franca pastro and mary stafford is gratefully acknowledged financial assistance for this research was provided by the british columbia youth employment program the university of alberta s central research fund and the president s research grant from simon fraser university in addition i am grateful for the comments made by chris hall terry heaps david ryan seminar participants at the university of alberta and two anonymous referees canadian journal of economics revue canadienne d economique xviii no 2 may 1985 printed in canada imprime au canada 0008 4085 85 377 94 1 50 c canadian economics association this content downloaded from 157 55 39 144 on mon 25 jul 2016 03 48 21 utc all use subject to http about jstor org terms

the distribution of health and income a theoretical framework a general framework is developed to analyse variations in the distribution of population health where individual health is modelled as a function of income conditional upon the level of another factor such as health related behaviour results are derived for the response of the level of average health in a population and the degree of health inequality to alternative health promotion policies and equiproportionate income growth qualitative results are shown to depend on characteristics of the individual health production functions and the frequency distribution of the other factor at each income level these results are independent of the distribution of income the discussion focuses on the implications of these results for contemporary research into inequalities in health and income

economic growth and emissions reconsidering the empirical basis of environmental kuznets curves abstract recent empirical research indicates that certain types of emissions follow an inverted u or environmental kuznets curve ekc as income grows this regularity has been interpreted as a possible de linking of economic growth and patterns of certain pollutants for developed economies in this paper the empirical basis of this result is investigated by considering some statistical particularities of the various ekc studies performed it is argued that the inverted u relationship between income and emissions estimated from panel data need not hold for specific individual countries over time based on insights from intensity of use analysis in resource economics an alternative growth model is specified and estimated for three types of emissions co2 nox and so2 in four countries netherlands uk usa and western germany it is found that the time patterns of these emissions correlate positively with economic growth and that emission reductions may have been achieved as a result of structural and technological changes in the economy sustainable growth is defined as the rate of economic growth that does not lead to growth in emissions its rate is calculated for each type of emission and country based on estimated parameter values the resulting indicators reflect a balance between the positive influence of growth and negative influence of structural change and technological progress on emission levels

economic growth and social development a longitudinal analysis of causal priority abstract the relationship between social and economic development is investigated using a lagged dependent variable model for 46 developing countries for the years 1960 1970 and 1980 our findings indicate that the two types of development are related and lend support to the trickle up hypothesis whether we use a 10 year or a 20 year lag period the physical quality of life index pqli has a significant and positive effect on gross domestic product gdp while gdp does not show a significant lagged effect on pqli the implications of our findings for policy research and implementation are discussed

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

domestic political conflict and basic needs outcomes an empirical assessment this study undertakes an empirical investigation of the near universal assumption that domestic political conflict is invariably harmful to the societies in which it occurs in particular we examine the implications of domestic conflict for the provision of basic human needs once the known effects of aggregate national wealth are removed using a variation of the panel regression model we regress an index of basic needs satisfaction on measures of domestic conflict scope and intensity along with suitable controls for a sample of 85 contemporary nations the findings indicate that the intensity measure is associated with long term improvements in basic needs while the scope of conflict carries a negative impact for basic needs outcomes

the effects of business to business e commerce on transaction costs this paper studies transaction costs changes arising from the introduction of the internet in transactions between firms we divide transaction costs into coordination costs and motivation costs we classify coordination efficiencies into three categories process improvements marketplace benefits and indirect improvements for motivation costs we focus on informational asymmetries we apply this framework to internal data from an internet based firm to measure process improvements marketplace benefits and motivation costs our results suggest potentially large process improvements and marketplace benefits we find little evidence that informational asymmetries are more important in the electronic marketplace than in the existing physical ones

global observation of ekc hypothesis for co2 sox and nox emission a policy understanding for climate change mitigation in bangladesh abstract environmental kuznets curve ekc hypothesis is critical to understanding the developmental path of a nation in relation to its environment how the effects of economic development processes dictate environmental changes can be found through the study of ekc to understand the ekc phenomena for climate change this study was undertaken by reviewing the available literature as co2 sox and nox are the significant greenhouse gases ghg responsible for global warming thus leading to climate change the study focused on those ghgs for ekc consideration with an understanding of the different ekc trajectories an attempt was made to determine the implications for the economic development of bangladesh in regards to the ekc it was shown that ekc for co2 was following a monotonous straight line in most cases sox were shown to follow the full trajectory of the ekc in most situations and nox was shown the hope only for the developed countries getting the low income turning point the type of economic policy that bangladesh should follow in regards to the discussed pollutants and sources is also revealed from these discussions contributions to policy stimulation in bangladesh are likely to be made

improving human development a long run view abstract the pessimistic flavour of the human development reports appears to be in contradiction with their own numbers as developing countries fare comparatively better in human development than in per capita gdp terms this paper attempts to bridge this gap by providing a new improved human development index ihdi informed by welfare economics the ihdi is presented here alongside the united nations development programme s undp hdi for the world and its main regions since the late 19th century social dimensions in the ihdi are derived following kakwani journal of development economics 41 1993 pp 307 336 with a convex achievement function whereas a geometric average is employed to combine its dimensions longevity knowledge and income thus the ihdi does not conceal the gap between rich and poor countries and casts a much less optimistic view than the conventional undp index while it fits with the undp concern for international differences the paper s findings highlight main weaknesses in human development dimensions of present day developing countries

the determinants of atmospheric so2 concentrations reconsidering the environmental kuznets curve this analysis explores the effects of income and the spatial intensity of economic activity on the atmospheric concentration of sulfur dioxide the results indicate that there is a u shaped relation between income and atmospheric concentration of so2 and an inverted u shaped relation between the spatial intensity of economic activity and so2 concentrations these results suggest that the spatial intensity of economic activity rather than income provides the impetus for policies and technologies that reduce so2 emissions based on this result the atmospheric concentration of so2 in developing nations may decline faster than indicated by previous analyses the potential for this decline depends on the rate at which income grows relative to population the trade off between the effects of income gains and the spatial intensity of economic activity on the atmospheric concentration of so2 is consistent with the notion that some environmental problems can be ameliorated by slowing population growth and increasing income levels

human development revisited a new undp report abstract the undp s first annual human development report is reviewed and discussed the report introduces a new index the human development index hdi as a counter to measures of national income such as gdp measuring development of countries with the aid of this index gives a significantly different ordering to one based on gnp per capita this point is not disputed although success on the index is not a necessary and sufficient condition for success in terms of rapid economic growth as is shown by the case of sri lanka nevertheless the report is welcome for its attention to human development issues for its useful statistical annex and for its observation that the poverty of the people of the developing world has been no barrier to the affluence of their armies

the environmental kuznets curve and sustainability a panel data analysis abstract in recent years sustainability has represented one of the most important policy goals explored in the environmental kuznets curve ekc literature but related hypotheses performance measures and results continue to present a challenge the present paper contributes to this ongoing literature by studying two different ekc specifications for 10 middle east and north african mena countries over the period 1990 2010 using panel data methods for the first specification namely ekc we show that there is an inverted u shape relationship between environmental degradation and income while for the second specification namely modified ekc mekc we show that there is an inverted u shape relationship between sustainability and human development hd the relationships are shaped by other factors such as energy trade manufacture added value and the role of law more interestingly findings from the estimation show that ekc hypothesis hd and sustainability are crucial to build effective environmental policies

human development and economic sustainability abstract this paper attempts to integrate the concern for human development in the present with that in the future in arguing for sustainable human development it appeals to the notion of ethical universalism an elementary demand for impartiality of claims applied within and between generations economic sustainability is often seen as a matter of intergenerational equity but the specification of what is to be sustained is not always straightforward the addendum explores the relationship between distributional equity sustainable development optimal growth and pure time preference

internal and international migration in mexico 1995 2000 using micro data from mexico and us 2000 population censuses and following a multi choice variant of roy s 1951 model this article pools into one model the determinants of internal and international migration in mexico while paying explicit attention to the potential problem of self selection the results reveal that ignoring multiple destinations in the migration decision might lead to erroneous inferences about the determinants of migration and the type of selection after controlling for wage differences the results suggest that single adult men with low schooling levels tend to migrate to the us while married women and men with higher levels of schooling tend to migrate within mexico we also found that there are strong differences between domestic and international social networks

maximizing human development the human development index hdi is widely used as a measure of well being we examine the allocations implied by the maximization of this index using a standard growth model maximization leads to consumption excluding education and health expenditures being pushed to minimal levels it also leads to the overaccumulation of education and or health capital and possibly physical capital relative to the standard golden rule we propose an alternative specification for the hdi where consumption replaces income as a proxy for decent standard of living maximization of this alternative implies a human development golden rule which balances consumption education and health expenditure we advocate the method of optimization subject to constraints for revealing the policy implications of taking an achievement measure and its underlying philosophy seriously

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

effectiveness of regulatory interventions on firm behavior a randomized field experiment with e commerce firms economic regulators use various instruments to stimulate smes to change their behavior but limited evidence exists on the effectiveness of such interventions we analyze the effectiveness of three ways of providing e commerce firms guidance about the legal rules on information disclosure the initial non compliance is considerable in two interventions firm specific guidance is given by post mail and by e mail respectively in another intervention guidance on industry level is given by means of dedicated publications and presentations in all cases the guidance was given on behalf of the regulatory authority the effectiveness of the firm specific guidance is measured through a randomized field experiment while for the industry guidance a panel analysis is conducted we find that sending the firms a letter by post mail slightly improved firm compliance but overall the various forms of guidance appear to be ineffective although information related interventions are commonly used in practice such regulatory interventions can fail to influence the behavior of smes

a comment on growth and equity in developing countries a reinterpretation of the sri lankan experience by bhalla and glewwe the inaugural issue of this journal contained an article by bhalla and glewwe which addresses some problems that arise in attempting to assess the relative success or failure of policies in different countries or policy regimes bhalla and glewwe 1986 p 36 their conceptual framework contrasts two approaches to raising economic welfare the direct or basic needs approach and the indirect or economic growth approach p 61 from 1960 to 1977 sri lanka is seen as approximating the first regime while the subsequent period following the change of government in 1977 is cast as having a closer correspondence to the second the general conclusion invited by the paper is that the change in policy orientation has been for the better the evidence suggests that the post 1 977 policies have not been detrimental to equity objectives and may offer more promise than those which they replaced p 62 in what follows i will suggest that bhalla and glewwe have exceeded the interpretations which their data will support accordingly their case cannot be sustained much as one would like to have answers to the questions they raise for my own part i share the majority view that sri lanka s system of food subsidies was and to some extent remains inefficient but it is surprising to find that bhalla and glewwe also question performance in the social field between 1960 and 1977 and that they totally ignore sri lanka s current state of disruption in their optimistic prognosis

hospital scale economies due to stochastic demand and service abstract this paper uses queuing theory to approximate empirically the potential for hospital scale economies due to the stochastic nature of hospital demand and service these results suggest that scale economies due to stochastic demand and service are likely to be important only for the consolidation of small specialized hospital units

climate change mitigation and agricultural development models primary commodity exports or local consumption production abstract the increasing demand for agricultural products partly due to the high population growth requires agriculture to struggle for productivity improvement however productivity search is constrained by environmental preoccupations raising the question of agricultural development models to be adopted to increase productivity while limiting environmental consequences this paper examines the role of market orientation by assessing the effect of agricultural commodity export on greenhouse gas emissions relatively to local market oriented agricultural production model using panel data from 1986 to 2010 for 136 countries around the world and accurate instrumental variables technique the findings suggest that the proportion of primary commodity export in agricultural production increases greenhouse gas emissions these results are robust to different sources of agricultural export and environmental data and to the inclusion of additional control variables

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

changes in the living standards of the poor in sri lanka during a period of macroeconomic restructuring abstract beginning in 1977 sri lanka moved away from its welfare oriented economy characterized by extensive government intervention in controlling prices and expensive consumer subsidies toward a more market oriented outward looking liberalized economy investment increased due largely to dramatic increases in the inflow of foreign capital combined with greater deficit financing unemployment declined and the rate of growth of gdp increased the major increase in foreign assistance coupled with deficit spending enabled the government to undertake the ambitious infrastructure projects that stimulated demand however this policy change had deleterious consequences for the poor rapid inflation which resulted in a decline of real wages coupled with dramatic decreases in the value of the food stamp scheme brought about a decline in calorie consumption for lower expenditure groups in addition levels of malnutrition as measured by acute wasting were higher after the policy change

the dynamic impact of renewable energy consumption on co2 emissions a revisited environmental kuznets curve approach this paper considers a revisited environmental kuznets curve ekc hypothesis with potential impact of renewable energy consumption on environmental quality to this end paper aims at investigating the validity of the ekc hypothesis employing the dependent variable of co2 emissions and regressors of gdp quadratic gdp and renewable energy consumption this paper hence analyzes this revisited ekc hypothesis to observe if i there exists an inverted u shaped relationship between environmental quality in terms of co2 emissions per capita income and per capita income squared and ii there exists a negative causality from renewables to co2 emissions within ekc model paper employs a panel data set of 17 oecd countries over the period 1977 2010 and launches panel fmols and panel dols estimations the findings support the ekc hypothesis for the panel and indicate that gdp per capita and gdp per capita squared have the impacts on co2 emissions positively and negatively respectively and that renewable energy consumption yields negative impact on co2 emissions another remark of this paper is that the validity of ekc does not depend on income level of individual countries of panel in which ekc hypothesis holds eventually paper argues that if countries carry out i policies i e for fair and easy access to the electricity from renewable sources and ii policies to increase renewables supply through i e improved renewable energy technologies they will be able to contribute to combating global warming problem as they increase their gdp s

macroeconomic conditions in the u s and congressional voting on environmental policy 1970 2008 using the environmental scorecard ratings of congressmen and senators published annually by the league of conservation voters we explore empirically whether political support for pro environment legislation aggregated across each legislative body is sensitive over time to changing economic conditions that is whether there is a political trade off between economic conditions and the environment using lcv scorecard ratings from 1970 to 2008 we find evidence consistent across both the house and senate that political support for the environment is related to per capita income but this general tendency can be decomposed into sharp differences by party

privatization and renationalization what went wrong in bolivia s water sector summary this paper investigates the impact of water service privatization in bolivia it compares the performance of cities in which the service was privatized la paz and el alto with a city in which it is managed as a cooperative santa cruz de la sierra and one where the service is publicly provided cochabamba we find that access to water by low income consumers increased under private provision however the concessionaire failed to meet the targets stipulated in the contract the tariff increases required for full cost recovery eventually led to public outrage that forced the government to renationalize the company

estimating country specific environmental kuznets curves from panel data a bayesian shrinkage approach designing an efficient global climate policy turns out to be a difficult yet crucial task since there are noteworthy cross country differences in energy and carbon intensities in this article the environmental kuznets curve ekc hypothesis is tested for carbon dioxide co2 emissions and as a modelling technique the iterative bayesian shrinkage procedure is employed to handle the cross country differences the results suggest that first the ekc hypothesis is rejected for 47 out of the 51 countries considered when the heterogeneity in countries energy efficiencies and cross country differences in the co2 emissions trajectories are accounted for second a classification of the results with respect to the development levels of the countries concerned reveals that the emergence of an overall inverted u shaped curve is due to the fact that in high income countries increase in gross domestic product gdp decreases emissions while in low income countries emissions and gdp are positively correlated

the heart kuznets curve understanding the relations between economic development and cardiac conditions abstract as countries turn wealthier some health indicators such as child mortality seem to have well defined trends however others including cardiovascular conditions do not follow clear linear patterns of change with economic development abnormal blood pressure is a serious health risk factor with consequences for population growth and longevity as well as public and private expenditure in health care and labor productivity this also increases the risk of the population in certain pandemics such as covid 19 to determine the correlation of income and blood pressure we analyzed time series for the mean systolic blood pressure sbp of men s population mmhg and nominal gross domestic product per capita gdppc for 136 countries from 1980 to 2008 using regression and statistical analysis by pearson s correlation r our study finds a trend similar to an inverted u shaped curve or a heart kuznets curve there is a positive correlation increase gdppc increase sbp in low income countries and a negative correlation in high income countries increase gdppc decrease sbp as country income rises people tend to change their diets and habits and have better access to health services and education which affects blood pressure however the latter two may not offset the rise in blood pressure until countries reach a certain income investing early in health education and preventive health care could avoid the sharp increase in blood pressure as countries develop and therefore avoiding the heart kuznets curve and its economic and human impacts

good and bad growth the human development reports abstract the 1996 human development report undp 1996 is about economic growth and human development in keeping with past reports in the series it emphasizes the diversity of country performance in improving human development indicators at given rates of growth this article reviews what the human development reports have said on this topic looking at how well the main messages have been supported by data and analysis and how compelling they are as a basis for public action

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

development of ecological economics in australia and new zealand abstract this paper reviews the development of ecological economics in australia and new zealand since its beginnings in the late 1970s a historical account is presented that focuses particularly on the activities of the australia new zealand society for ecological economics and key ecological economics research activities achievements of ecological economics in australia and new zealand are assessed using a range of quantitative and qualitative data the main areas of expertise developed by australian and new zealand ecological economists were found to be theoretical foundations and visions for ecological economics biodiversity and resilience input output analysis heterodox valuation approaches analysis of economy environment interactions sustainability indicators sustainable agriculture fisheries and oceans and energy thermodynamics both countries are ranked at the top or near the top of the world rankings in terms of per capita isee membership and publication rates in ecological economics a defining feature of ecological economics in australia and new zealand has also been its practical and problem solving focus and the level of end user engagement the paper concludes by discussing the challenges that face the future development of ecological economics in australia and new zealand

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

the operation of the hospital sector towards a diagnosis it is not surprising to find that most of the existing medical economics research has focused attention on the hospital sector since over 50 percent of all health care expenditures in most western countries cover hospital expenses what is surprising is the lack of a unified economic model for the operation of the hospital sector that goes beyond a piecemeal explanation for some specific institutional regularity it is the intent of this paper to use a traditional economic model of maximizing behavior to develop a general analysis of the hospital sector behavioral models of hospitals are surveyed by jacobs 28 many of the approaches are variants of the classic baumol model of output maximization 2 newhouse 36 and feldstein 17 consider utility maximization subject to a budget constraint with utility a function of both the quality and quantity of medical services in contrast pauly and redisch 38 examine a model in which physicians take an active role in determining the behavior of the not for profit hospital physicians with fixed hours of work maximize net per capita income recently harris 26 has offered a description of the internal operation of hospitals in which both physicians and administrators take an active role in management although the models mentioned provide specific predictions they do not provide a general analysis of the hospital sector furthermore questions concerning market segmentation alternative reimbursement procedures cost management waiting times bed management and occupancy rates are not addressed these issues are addressed in the model formulated in this paper the formal analysis of the present paper is developed within the environment of third party insurance in which all medical services offered by hospitals are financed out of general insurance revenues while consumers face no user charges 2 the technique of equalizing differences formalized by rosen 41 is used to analyze hospitals under competi

an econometric analysis of health care expenditure a cross section study of the oecd countries this paper is an empirical examination of the determinants of aggregate health care expenditure the paper presents a systematic analysis of relationships across 19 oecd countries showing the effects of aggregate income institutional and socio demographic factors on health care expenditure the results indicate that institutional factors of the health systems in addition to per capita gross domestic product gdp contribute significantly to the explanation of the health care expenditure variation between countries for example the way physicians in outpatient care are paid and the mixture of public private funding and inpatient outpatient care

income distribution and co2 emission a comparative analysis for china and india abstract the aim of this paper is to test whether income inequality contributes to environmental degradation in china and india where both countries are giving a great concern about the implications of their unsustainable energy consumption to the environment not only to themselves but also to the global environmental sustainability by applying the bounds test approach to cointegration we found in both countries a long run but not a statistically significant relationship between income inequality and co 2 emissions both in the long run and in the short run the robustness of our cointegration results is also ascertained by using three different long run tests furthermore applying the variance decomposition analysis to examine the dynamic causal relationship between the gini coefficient of income distribution and co 2 emissions we found that income inequality was the least important factor in determining co 2 emissions and that there was no causality running in any direction between co 2 emissions and income inequality in both countries still income and energy consumption are the major determinants of co 2 emissions in both countries nevertheless even though the evidence is not statistically significant in the case of china it indicates that reducing income inequality can have a positive impact on environmental quality while in india redistributing income to improve environmental degradation may not be effective

small business survival and sample selection bias analyses of small business and the factors affecting their survival are fairly common in the research literature the level of research interest may stem from the fact that in the us only about half of all new small businesses survive after 4 years headd 2003 however research attempting to understand the phenomenon that employs data using only information from and about surviving firms may lead to erroneous conclusions regarding the factors that influence firm survival and failure in this paper we provide evidence that omitted information about the firms that disappear from the research data over time leads to biased coefficient estimates comparing the heckman two step estimation approach of switching regression models to a semi parametric cox hazard model the accelerated failure time aft model we conclude that the cox atf approach is the most appropriate model for firm survival analysis

does skewed pattern of income distribution matter for the environmental quality evidence from selected brics economies with an application of quantile on quantile regression qqr approach abstract using annual data from 1980 to 2014 the study explores the relationship between carbon emissions and skewed pattern of income distribution among 4 selected brics economies e g brazil india china and south africa using quantile on quantile regression qqr technique of sim and zhou 2015 it tries to contribute towards an empirical understanding on the quantile structure of both the variables for the selected brics countries it finds for india and brazil that as income rises although both lower and upper income people degrade the environmental quality by releasing more co2 emissions but interestingly it is the poor who intensively degrade the environmental quality than the rich in sharp contrast for china and south africa it finds that it is the poor who relatively contribute less to the environmental degradation by reducing co2 emissions than the rich these findings have greater policy significances which are discussed at the concluding section in greater detail

energy innovation and renewable energy consumption in the correction of air pollution levels abstract this study analyses the relationship between economic growth and environmental pollution specifically it investigates the presence of an environmental kuznets curve ekc in 17 oecd countries over the period of 1990 2012 the results confirm the existence of an n shaped ekc relationship between income and environmental degradation the study offers a novel methodological contribution that makes it possible to explain the environmental pollution process through the analysis of low carbon technologies this demonstrates how income levels affect energy consumption and how higher energy demand leads to a larger share of fossil sources in the energy mix and thus increased greenhouse gas ghg emissions the effect on per capita ghg emissions is explored in a model containing a dampening variable that moderates the relationship between energy consumption and income this empirical evidence helps to explain the interaction between energy regulation economic growth and carbon emissions this study also confirms the positive effect that energy innovation process exerts on environmental pollution finally it is noted that renewable energy sources help to improve air quality

the inequality adjusted human development index a constructive proposal abstract this paper proposes a method to incorporate a concern for distributional inequalities of income education and longevity into the framework of the human development index hdi as it is presently designed by the united nations development programme the paper constructs gini coefficients for a set of 20 developing countries measuring inequalities in annual income educational attainment and life span attainment these calculations are combined with data from the hdi to produce an inequality adjusted human development index iahdi the implications of this proposed index for evaluating and promoting development are considered

the role of education in the environmental kuznets curve evidence from australian data abstract this paper is based on the underlying idea that the use of energy resources in a society significantly depends on their level of education then it is hypothesized that education might directly affect environmental quality by worsening it at early stages and improving it once education expands from its certain level thus we pursue an extension of the standard environmental kuznets curve by including an indicator of the evolution of citizens education this empirical strategy might avoid bias on income coefficients and in turn assess the value of education as environmental policy an application for australia is given to illustrate this possibility by using higher education data for a large time span 1950 2014 empirical results suggest that in most of the studied period expansion in education rate has increasingly compensated the rise of per capita co 2 emissions stemming from the economic growth moreover only in recent years both per capita income and education expansion have been proved to reduce emissions however provided that income growth is difficult to manage it would be worth considering the possibility of promoting education in order to achieve environmental objectives

redd and forest transition tunneling through the environmental kuznets curve abstract international attention is focused on finding ways to reduce emissions from deforestation because of the emerging concerns over climate change however the causes of deforestation are rooted in current economic and development paradigms the causes of deforestation also vary across different geographical regions and have implications for the forest transition attempts to reach an international agreement on curbing deforestation have achieved little success despite over 30 years of un negotiations new initiatives from redd reducing emissions from deforestation and forest degradation could provide financial incentives to curb deforestation hence alternative development paths for forest cover changes and forest transition are analyzed for the redd policy within the framework of an environmental kuznets curve ekc for deforestation the ekc models are estimated for geographical regions of latin america africa and asia the results based on the panel data analysis of 43 countries covering the period 1970 1994 provides evidence that an inverted u shaped ekc fits for latin america and africa while a u shaped ekc applies to asia the results also indicate that strengthening agricultural and forestry sector policies are important for curbing deforestation the ekc models estimates could provide guidance for decisions on financing the redd policy as specific to each region

basic human needs the plateau curve abstract the satisfaction of basic human needs in developing countries follows a nonlinear curve relative to per capita income asymptotically approaching a limiting level within this general relationship some countries are more efficient than others in improving basic needs at lower per capita income levels infant mortality rates in 116 countries from 1950 to 1980 are analyzed to identify factors affecting a country s efficiency in reaching infant mortality targets relative to its gross domestic product per capita the determinants of efficiency include export structure internal distribution late development and access to education implications for development policy are discussed

poverty human development and growth an emerging consensus this paper considers several issues relevant to the debate on the extent to which poverty or development progress in general should be measured by income or by a broader set of objectives issues covered here are practical implications of the two approaches for poverty reduction efforts the impact of growth on basic social indicators and how national achievement on social indicators is best measured sri lanka and pakistan countries often cited in this debate are used as examples

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

the impact of environmental regulation shadow economy and corruption on environmental quality theory and empirical evidence from china abstract mounting environmental pressures led china to focus on the effectiveness of the environmental regulation to control pollution since the shadow economy or underground economic activities that are not included in official statistics accounts for an increasing fraction of china s economy its impacts on environmental quality should be carefully evaluated in this study the main research questions are as follows 1 what is the extent of the effect of environmental regulation on environmental quality and 2 what are the factors that influence the impact of environmental regulation on environmental pollution a theoretical model is developed to explain the relationship among the environmental regulation shadow economy and environmental quality in china an empirical analysis is conducted to test the three propositions of the model thereby examining the explanatory power of the theoretical model concretely using panel data from 30 provinces for the period of 1998 2012 the generalized method of moments gmm method is employed to control for potential endogeneity and introduce dynamic effects the estimation results indicate that stringent environmental regulation and the level of the shadow economy are both positively related to china s environmental pollution however the results also indicate that tighter environmental control would help reduce pollution at a given level of the shadow economy moreover an increase in the proportion of corrupt officials may weaken the environmental regulation which would consequently lead to the increase in illegal production and total pollutant emissions besides many economic and social factors may also affect the environmental quality for instance the development of secondary industry contributes toward an increase in pollutant emissions however increased research and development r d spending on eco friendly industrial operations can help to reduce pollution

performance in living standards abstract our ultimate objective is to enhance the standard of living of our societies but the standard of living has different meanings for different people a thorough investigation of the concept of the standard of living has been made only recently by sen who defines it in terms of functioning and capabilities functioning is an achievement whereas capability is the ability to achieve the main objective of the present paper is to compare achievements levels and improvement changes in the standard of living across countries using an axiomatic approach an achievement index is derived which accomodates the view that a further increase in the standard of living of a country when it is already at a higher level signifies an achievement greater than that of another with an equal increase but from a lower base the paper also tests for the statistical relationship between indicators of the countries standards of living so derived in their capita gdp the question posed is whether the aggregate income which provides people with the means to achieve a better life can be used as proxy measure of the standard living and extent to which the country s improvement in the standard of living can be explained by the levels and changes in the per capita income the analysis presented in the paper is based on the data from 80 developing countries

measuring pro poor growth in non income dimensions current concepts and measurement of pro poor growth is entirely focused on the income dimension of well being this neglects non income dimensions of poverty and the multidimensionality of poverty and wellbeing in this paper we introduce the multidimensionality of poverty into the measurement of pro poor growth measurement by applying the growth incidence curve to non income indicators we develop growth incidence curves and calculate the associated ravallion chen pro poor growth measures for a range of non income indicators such as education mortality vaccinations stunting and a multidimensional wellbeing measure and are thereby able to study improvements in these dimensions of well being at various points of the distribution of those indicators as well as at various points of the income distribution this way we can determine whether improvements in non income indicators were pro poor in an absolute or relative sense we illustrate this empirically for bolivia between 1989 and 1998 and find that growth was relatively pro poor in the non income dimension results for absolute improvements are less clear

is environmental degradation an inevitable consequence of economic growth tunneling through the environmental kuznets curve abstract economywide reforms often contribute simultaneously to economic social and environmental gains however unintended adverse side effects occur in many cases when such growth inducing reforms are undertaken while neglecting other policy market or institutional imperfections the remedy does not generally require reversal of the original economywide reforms but rather the ex ante implementation of additional complementary measures that remove such imperfections the ekc approach seeks to relate the state of the environment to the stage of development developing countries could learn from the experiences of industrialized nations and restructure growth and development to tunnel through any potential ekc thereby avoiding going through the same stages of growth that involve relatively high and even irreversible levels of environmental harm an environmentally adjusted measure of national income could significantly change the shape of the development environment relationship recommendations for decision making include actively seeking win win policies that simultaneously yield both economic and environmental gains pre empting environmental harm through ex ante remedial measures and fine tuning reform policies to avoid severe environmental damage the adoption of more sustainable policies will facilitate the attainment of higher levels of development at a lower environmental cost

liberalization and inequality in sri lanka a comment abstract paul glewwe has recently argued against the widely held view that the liberalizing policy reform in sri lanka in the late 1970s increased inequality we contend here that glewwe has not convincingly discredited the household income distribution data that he has misinterpreted the expenditure distributions and that he has not considered the welfare distributional effects of the relative price changes induced by the policy reforms furthermore we argue that a sound basis remains for the contention that the policy reforms of the late 1970s increased inequality

the diffusion of e commerce among smes theoretical implications and empirical evidence as a specific institution of distributive trades e commerce displays similarities with retail stores and mail order companies as well as providing theoretical support for the assumption that e commerce is a way to sell certain goods and services at prices potentially lower than those of traditional distributive channels this paper analyses its inter firm diffusion among a sample of firms mostly smes in italy the paper has three main purposes firstly it challenges the view of e commerce as a technological revolution by pointing out its nature as a cost minimizing marketing channel in particular it shows how under certain conditions e commerce is a source of transaction cost advantages analogous to those yielded by mail order business secondly the paper identifies from a theoretical viewpoint the circumstances under which e commerce sales might achieve a significant level of penetration among those smes that would otherwise incur high costs in organizing a proprietary distributive channel thirdly it employs a unique data set of italian manufacturing service and hospitality firms nearly 90 of them with fewer than 100 employees to estimate a diffusion model based on the logistic curve according to the estimates by the fourth quarter of 2003 nearly 50 of the population of firms in the geographical area surveyed will have introduced e commerce among their marketing channels

growth and equity in developing countries a reinterpretation of the sri lankan experience in the important debate between the proponents of direct basic needs and indirect economic growth measures of promoting welfare sri lanka has frequently been cited as one country which has successfully pursued the direct approach it has raised living standards without much cost in terms of reduced growth this conclusion however is based on analyses which do not account for the initial conditions of the countries being compared after methodologically incorporating these concerns neither the improvement in living standards nor the 2 0 percent per capita growth rate during the period of direct policy measures 1960 78 was exceptional in contrast during the period of more indirect growth promoting policies 1977 84 i economic growth more than doubled to an average rate of 4 3 percent per capita per annum ii expenditure inequality did not significantly change iii consumption expenditures of the population and the poor generally increased and iv several living standard indicators continued to improve
