income inequality and growth does the relationship vary with the income level abstract for three different specifications of a cross country growth model the coefficient of initial income inequality is remarkably similar for high and low income countries contrary to some recent suggestions in the literature but varies markedly across models

photovoltaic investment roadmaps and sustainable development abstract this paper analyzes the potential contributions of photovoltaic energy to sustainable development in its three dimensions environmental economic and social for that purpose the capacity deployments proposed by the main international institutions in the field are considered mainly the international energy agency the paper focuses on the monetary valuation of avoided co2 emissions and the assessment of the required financial funds the risk implied by the uncertain photovoltaic prices are dealt with and methods to manage it are suggested it is shown that valuing emission at a conservative price and properly discounted would be enough to finance on average the required investments thus a low carbon tax is all that would be required to finance the investments

average cost pricing versus serial cost sharing an axiomatic comparison abstract a finite group of agents share a one output production function a cost sharing rule allocates the total cost among the users for every conceivable profile of output demands we investigate the space of possible cost sharing rules from an axiomatic perspective we provide two characterizations of average cost pricing one based on the axioms of additivity and monotonicity both with respect to the cost function and the other based on the axioms of additivity and a version of consistency we also provide a characterization of serial cost sharing based essentially on additivity and a free lunch axiom journal of economic literature classification numbers d63 d78 c79

human capital inequality and economic growth some new evidence this paper provides new measures of human capital inequality for a broad panel of countries taking attainment levels from barro and lee 2001 we compute gini coefficients and the distribution of education by quintiles for 108 countries over five year intervals from 1960 to 2000 using this new cross country data on human capital inequality two main conclusions are obtained first most countries in the world have tended to reduce the inequality in human capital distribution second human capital inequality measures provide more robust results than income inequality measures in the estimation of standard growth and investment equations

research advances in environmentally and socially sustainable operations abstract consumers and governments are pressuring firms to strike a balance between profitability and sustainability however this balance can only be maintained in the long run if the firm can take a holistic approach to sustain the financial flow profit resource flow planet and development flow people for the entire ecosystem comprising poor producers in emerging developing markets global supply chain partners consumers in developed countries and the planet by considering the flows associated with different entities within the ecosystem we classify and summarize recent operations research management science or ms research developments also we identify several gaps for future research in this important area

a meta analytic reassessment of the effects of inequality on growth this paper develops a meta analysis of the empirical literature that estimates the effect of inequality on growth it covers studies published in scientific journals during 1994 2014 that examine the impact on growth of inequality in income land and human capital distribution we find traces of publication bias in this literature as authors and journals are more willing to report and publish statistically significant findings and the results tend to follow a predictable time pattern over time according to which negative and positive effects are cyclically reported after correcting for these two forms of publication bias we conclude that the high degree of heterogeneity of the reported effect sizes is explained by study conditions namely the structure of the data the type of countries included in the sample the inclusion of regional dummies the concept of inequality and the definition of income in particular our meta regression analysis suggests that cross section studies systematically report a stronger negative impact than panel data studies the effect of inequality on growth is negative and more pronounced in less developed countries than in rich countries the inclusion of regional dummies in the growth regression of the primary studies considerably weakens such effect expenditure and gross income inequality tend to lead to different estimates of the effect size land and human inequality are more pernicious to subsequent growth than income inequality is we also find that the estimation technique the quality of data on income distribution and the specification of the growth regression do not significantly influence the estimation of the effect sizes these results provide new insights into the nature of the inequality growth relationship and offer important guidelines for policy makers

making real progress toward more sustainable societies using decision support models and tools introduction to the special volume academics politicians professionals and the general public are aware that without stewarding our planet s natural resources man is on the pathway towards a global collapse over the next three decades mankind is expected to consume an estimated 140 billion tons of minerals ores fossil fuels and biomass per year three times current consumption social welfare and human wellbeing are threatened with the scarcity of natural resources consequently nations and their societies are also at risk of collapse the readers of this special volume will find a compilation of scholarly research papers with real life applications that take the challenge of proposing decision making models and tools to address sustainability challenges in integrative ways the main focus of this special volume is integration of sustainability dimensions economic social environmental ethical and time into decision support models and to identify pathways to achieve more sustainable societies the majority of the research in this special volume 74 percent focuses on environmental and economic dimensions only 26 percent integrated social dimensions with them methodologically a range of mathematical models and tools are presented to support prescriptive decision making with some descriptive models integrated to support decision makers in solving practical problems across a variety of industries and scenarios the breadth and complexity of issues facing organizations and society requires innovative applications of these methodologies the concerns cover a spectrum ranging from energy to solid waste management a multitude of levels from broad based policy concerns to strategic inter organizational sustainable supply chain management and significantly shop floor operational issues are also covered the variety of problems and solutions exemplifies the potential for modelling and operations research for addressing some of our world s most pressing concerns

a multicriteria method for environmental management system selection an intellectual capital approach abstract the adoption of environmental management systems has become more widespread among those firms looking to minimize their environmental impacts considering that firms have to select the optimal management system from a set of possible alternatives this paper presents a novel decision making approach based on the multicriteria method of analytic network process in order to evaluate and prioritize the implementation of environmental management system alternatives in for profit firms since several relevant intangible benefits are derived from the adoption of this kind of management system such as enhancing employees knowledge and skills as well as improving corporate reputation the method integrates and quantifies both financial and non financial intellectual capital value creation criteria in order to identify the alternative that maximizes a firm s total market value the proposed approach is empirically tested in a group of spanish olive oil firms with a proactive environmental management orientation and the results confirm the reliability of the proposed model furthermore the empirical applications reveal that all the olive oil firms attribute great importance to the intangible elements when assessing environmental management systems these results suggest that it is appropriate to take into account the intellectual capital value resulting from these kinds of management systems during the decision making process the proposed method formalizes the evaluation process that firms already employ these firms certainly take non financial capital value creation elements into account albeit in an intuitive way

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

price and warranty period decisions for complementary products with horizontal firms cooperation noncooperation strategies abstract the purpose of this paper is to explore the optimal strategies on price and warranty period of two complementary products in a supply chain with two manufacturers and one common retailer from a two stage game theoretic perspective five decentralized models are established by considering the two manufacturers cooperation noncooperation strategies and the firms different bargain powers the corresponding closed form expressions for equilibrium decisions are obtained through a systematic analysis and comparison some interesting and valuable managerial insights are established we find that the retailer always has the advantage to get the higher profit when she is a leader however this is not always valid for two manufacturers for example two manufacturers profits when they are leaders and they adopt the noncooperation strategy in the supply chain are lower than that when two manufacturers and the retailer have the identical market power all channel members as well as consumers benefit from lower retail prices longer warranty periods and larger profits when the two manufacturers adopt cooperation action

a new unified approach to evaluate economic acceptance towards main green technologies using the meta analysis the aim of this paper is to analyze the main determinants of the economic acceptability of four green technologies gts alternative fuel vehicles energy savings in residential buildings smart meters and renewable electricity using a meta analysis on a sample of 35 selected papers which provided 245 primary data this approach allows detecting relationships across heterogeneous studies avoiding the subjectivity of qualitative surveys we implement a new two step procedure first we compute a measure of the implicit price for a kilogram of co2 avoided pco2 homogenizing the usable information for the gts considered second we conduct a meta regression using the computed pco2 values to estimate the socio economic determinants impact in general our results show a wide degree of acceptability for gts which is stronger among european citizens in particular it emerges that on average the estimated pco2 is positive for the gts considered and additional positive effects exist when respondents are confronted with an explicit reference to quantitative targets in terms of co2 abatement a clear proposal for payment timing and a specific renewable electricity mix these results indicate that information and transparency are crucial to spur gts deployment therefore to support gts market penetration public and private institutional stakeholders have to provide ad hoc information to the end users setting a clear and suitable system of prices to increase the economic value end users place on gts

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

production planning of multi stage multi option seru production systems with sustainable measures abstract with the concerns over climate change and the escalation in worldwide population sustainable development attracts more and more attention of academia policy makers and businesses in countries sustainable manufacturing is an inextricable measure to achieve sustainable development since manufacturing is one of the main energy consumers and greenhouse gas contributors in the previous researches on production planning of manufacturing systems environmental factor was rarely considered this paper investigates the production planning problem under the performance measures of economy and environment with respect to seru production systems a new manufacturing system praised as double e ecology and economy in japanese manufacturing industries we propose a mathematical model with two objectives minimizing carbon dioxide emission and makespan for processing all product types by a seru production system to solve this mathematical model we develop an algorithm based on the non dominated sorting genetic algorithm ii the computation results and analysis of three numeral examples confirm the effectiveness of our proposed algorithm

using data envelopment analysis for estimating energy saving and undesirable output abatement a case study in the organization for economic co operation and development oecd countries abstract environmental protection is one of the main concerns of the international community countries show meticulous attention to environmental issues by considering eco efficiency the eco efficiency evaluation of countries is a complex and multidisciplinary topic data envelopment analysis has widely been applied to measure the eco efficiency of organization for economic co operation and development countries in previous studies energy inputs have not been contemplated the subject becomes more important when there are non discretionary factors in this paper the eco efficiency of countries in the organization for economic co operation and development is assessed given energy inputs undesirable outputs and non discretionary factors to this end slack based and range adjusted measures are extended also new environmental indices are introduced the relationship between consumption of energy inputs and production of undesirable outputs can be addressed by two new environmental indices spearman correlation test indicates a direct and positive relationship between potential of energy saving and potential of undesirable output abatement france germany luxemburg norway sweden and the united kingdom are recognized as eco efficient countries south korea and italy have the highest and lowest potential for energy saving respectively poland and iceland are countries with the highest and lowest potential for undesirable output abatement respectively it can be concluded that countries producing high undesirable outputs may not operate eco efficiently and thus have an extreme potential to save the optimum energy moreover countries consuming low energy may operate eco efficiently and have a low potential to reduce undesirable outputs

income inequality education expenditures and growth abstract recent studies have reported a negative association between income inequality and economic growth if true what accounts for this finding what are possible transition mechanisms that might link the two this paper explores one such mechanism income inequality raises expenditures for public education as a fraction of gross domestic product gdp although public education expenditures are positively associated with future economic growth the contemporaneous effect upon growth is negative given this cost upon current growth these findings may help to explain the lack of a large positive effect from the growth of human capital upon economic growth as reported in the literature

a new data set measuring income inequality this article presents a new data set on inequality in the distribution of income the authors explain the criteria they applied in selecting data on gini coefficients and on individual quintile groups income shares comparison of the new data set with existing compilations reveals that the data assembled here represent an improvement in quality and a significant expansion in coverage although differences in the definition of the underlying data might still affect inter temporal and international comparability based on this new data set the authors do not find a systematic link between growth and changes in aggregate inequality they do find a strong positive relationship between growth and reduction of poverty

accelerating the transition towards sustainability dynamics into supply chain relationship management and governance structures abstract stakeholders and competitive priorities drive profit and non profit organizations towards the implementation of sustainability related measures in their internal operations and in their supply chains planning it is believed by some that investments in sustainability may help them to attain more successful futures by maintaining a healthy balance among economic environmental and social resources dimensions consequently some organizations have begun to integrate these dimensions in recent years researchers and practitioners are also working to accelerate the transition for more equitable sustainable post fossil carbon societies by working with all relevant stakeholders this special volume of journal of cleaner production is focused upon on diverse types of supply chain relationships governance mechanisms and innovations which can foster effective and efficient sustainable supply chain management this volume is comprised of twenty seven articles and a book review fifteen of the articles address the supply chain relationships domain while five focus primarily upon governance five upon innovation and two on relationships and governance however there is a huge potential to further explore the opportunities towards achieving sustainability by implementing proper governance mechanisms and eco innovation strategies research from low income countries dealing with sustainability issues are also urgently needed

promise and pitfalls in the use of secondary data sets income inequality in oecd countries as a case study this paper examines the role of secondary data sets in empirical economic research taking the field of income distribution as a case study we illustrate problems faced by users of secondary statistics showing how both cross country comparisons and time series analysis can depend sensitively on the choice of data after describing the genealogy of secondary data sets on income inequality we consider the main methodological issues and discuss their implications for comparisons of income inequality across oecd countries and over time the lessons to be drawn for the construction and use of secondary data sets are summarized at the end of the paper

inequality and growth uncovering the main conclusions from the empirics abstractthis paper is a critical survey of the empirical literature on the effects of inequality on economic growth we conclude that it is most likely that the disparities found in the results are due to differences in the type of countries and time periods included in the samples the variable used to measure inequality the structure of the data and the estimation techniques these findings suggest that the mechanisms that link inequality to growth are likely to operate differently in different circumstances an element that may offer important guidelines for both policy makers and researchers

economic growth energy intensity and the energy mix abstract this paper explores how changes in energy intensity and the switch to renewables can boost economic growth to do so we implement a dynamic panel data approach on a sample of 134 countries over the period 1960 to 2010 we incorporate a set of control variables related to human and physical capital socio economic conditions policies and institutions which have been widely used in the literature on economic growth given the current state of technology improving energy intensity is growth enhancing at the worldwide level moreover conditional to energy intensity moving from fossil fuels to frontier renewables wind solar wave or geothermic is also positively correlated with growth our results are robust to the specification of the dynamic panel with respect to alternative approaches pooled ols within group or system gmm and to alternative specifications accounting for heterogeneity across countries a set of institutional factors and other technical aspects

the incidence of visible underemployment evidence for trinidad and tobago this article presents an empirical analysis of the incidence of visible underemployment in trinidad and tobago visible underemployment consists of workers who work less than the normal duration of working hours but are willing and available to work more we find that compared to other groups of the labour force the visibly underemployed tend to be less educated and are more likely to work in the private sector we also find that their revealed behaviour is consistent with their desire for more hours only about 50 per cent of the visibly underemployed are able to find full time employment within three months and little except firm size helps predict who will

a quantitative model for environmentally sustainable supply chain performance measurement abstract the development of robust mechanisms for supply chain performance measurement have been identified as an integral step needed for the transition towards sustainable supply chain systems and a greener global economy however measuring the environmental performance of supply chains is a challenging task due to several factors such as the lack of standardised methodologies and the inherent multi criteria nature of the problem by leveraging the capability of a multi regional input output framework to handle the complex and global nature of supply chains the current work presents a robust environmental sustainable performance measurement model underpinned by industrial lifecycle thinking as a result some theoretical insights are provided and an empirical application of the model to the metal products industry of the brics brazil russia india china and south africa nations undertaken in an attempt to address some of the methodological and applied measurement challenges in particular this allowed the modelling of carbon emissions trends within and between the brics nations and with the rest of the world over a 20 year period 1992 2011 as well as providing an opportunity to hypothesis on their future carbon emissions performances specific analyses of the metal product industry showed that demand represents the main driver for the increasing carbon footprint however the overall decline in reported carbon footprint was due to improvements in emissions intensity and efficiency gains induced by technology the study further assesses the effects of imports and economic growth on carbon footprint and discusses the implications of the study to sustainability transition processes in the brics nations

the economic order quantity model revisited an extended exergy accounting approach abstract the economic order quantity eoq model has been popular among academicians and practitioners for decades despite the many variants of the eoq that have appeared in the literature to fine tune it to reality it still has limitations a major one is that it does not take into account the hidden costs inherent in inventory systems some of these costs relate to sustainability issues including environmental social labor and economic effects this paper considers some of these costs referred to as the exergetic costs and estimates them using the extended exergy accounting eea approach extended exergy accounting assigns equivalent exergetic values to capital labor and environmental remediation costs of a system the analysis combines the classical exergy analysis with the sustainability factors which are the labor capital and environment the paper uses an exergetic model to determine the eoq inventory policies for three firms operating in the usa germany and china the results show that the eoq is different for the three firms because the equivalent exergy of capital labor and environment remediation costs is different in each country

inequality and economic growth the empirical relationship reconsidered in the light of comparable data all of the recent empirical work on the relationship between income inequality and economic growth has used inequality data that are not consistently measured this paper argues that this is inappropriate and shows that the significant negative correlation often found between income inequality and growth across countries is not robust when income inequality is measured in a consistent manner using data from the world income inequality database however evidence is found of a significant negative correlation between consistently measured inequality of expenditure data and economic growth for a sample of developing countries

what is the impact of international remittances on poverty and inequality in latin america workers remittances have become a major source of income for developing countries however little is still known about their impact on poverty and inequality using a large cross country panel dataset the authors find that remittances in latin american and caribbean lac countries have increased growth and reduced inequality and poverty these results are robust to the use of different instruments that attempt to correct for the potential endogeneity of remittances household survey based estimates for 10 lac countries confirm that remittances have negative albeit relatively small inequality and poverty reducing effects even after imputations for the potential home earnings of migrants

measuring development with inequality how should aggregate indicators of development account for inequality abstract the paper analyzes how inequality is accounted for in aggregate indicators of development and whether and how it should be used the motivation behind the study stems from the renewed interest in inequality in academia public discourse and in global policy first we argue that inequality should be considered when constructing development indicators the role of distribution in development is important both because people generally prefer lower inequality and inequality tends to have negative effects on development outcomes second we analyze how ten selected development indicators account for inequality in terms of justification type of inequality measure of inequality and method of incorporation and what the strengths and weaknesses of different approaches are we found considerable diversity especially for inequality measures and methods of incorporation as for the type of inequality inequality of opportunities is considered marginally and overlapping inequalities not at all increasing data availability opens the door for inclusion especially for the latter aspect as most indicators suffer from insufficient methodological substantiation we argue for increased clarity regarding why and how inequality is accounted for in development indicators the analysis is complemented by a detailed review of treatment of inequality by the analyzed indicators annex

eco efficiency change in power plants using a slacks based measure for the meta frontier malmquist luenberger productivity index abstract malmquist luenberger index is a popular index deployed for evaluating eco efficiency and productivity change over a certain period when both desirable and undesirable factors are jointly produced in some production processes however conventional data envelopment analysis dea models used for computing this index are unable to distinguish the various technologies employed by the decision making units when heterogeneity exists in the technology the meta frontier malmquist luenberger approach is adopted to evaluate eco efficiency and productivity change over a period when undesirable outputs are incorporated in the analysis of efficiency in this paper a new slacks based dea measure is developed and used to compute the meta frontier malmquist luenberger productivity index this approach is then deployed to evaluate 48 iranian thermal power plants productivity change in three different categories steam gas and combined cycle over an eight year period of restructuring in the power industry this technique enables the calculation of eco efficiency change of thermal power plants operating under different technologies as well as the technology gap ratios and measures the extent to which the efficiency frontiers of individual categories of power plants deviate from the meta frontier the results reveal that the last years of the restructuring period saw a greater rate of productivity growth compared to the initial years and evidence of significant eco efficiency improvements over the period in all the three types of the thermal power plants finally it is expected that the findings in this study aid policy makers and power industry regulators in developing sustainable energy policies towards environmental protection and planning power plant operations

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

inequality is bad for growth of the poor but not for that of the rich the paper assesses the impact of overall inequality as well as inequality among the poor and among the rich on the growth rates along various percentiles of the income distribution the analysis uses micro census data from u s states covering the period from 1960 to 2010 the paper finds evidence that high levels of inequality reduce the income growth of the poor and if anything help the growth of the rich when inequality is deconstructed into bottom and top inequality the analysis finds that it is mostly top inequality that is holding back growth at the bottom

the simultaneous evolution of growth and inequality research on inequality and growth can be divided into two strands one deriving from kuznets and lewis has tried to identify a mechanistic relationship between growth or level of income and inequality the other has tried to find causal explanations of growth and inequality treating each independently in this paper we draw from both strands to test whether growth and inequality are the joint outcomes of other variables and processes we find that simultaneous examination of growth and inequality yields significantly different results and has different consequences for policy from previous independent studies the empirical literature on growth and inequality can be divided into two broad strands one following the pioneering work of kuznets and lewis is motivated by the pessimistic conjecture that the process of growth and development somehow requires increasing inequality at least in the early stages this has led to many efforts to identify a mechanical relationship between the level of development and inequality anand and kanbur 1993 or to determine whether faster growth requires higher or lower inequality the second strand has sought to identify the causal factors influencing the evolution of growth and inequality independently this research has looked either at growth for example barro and sala i martin 1995 or at inequality li et al 1997 but has not tried to identify those factors that might simultaneously influence both growth and inequality 2 thus the literature that looks simultaneously at growth and inequality descending most notably from kuznets 1955 relates them in a mechanistic manner that ignores or minimises the role of other causal factors including policy while the literature that incorporates other causal factors including policies looks independently at growth and inequality neither approach is particularly convincing from a theoretical standpoint the evolution of growth and inequality must surely be the outcome of similar processes in addition neither approach is particularly useful for the policy maker who needs to balance the impact of policies on both growth and distribution in this paper we investigate whether growth and inequality are simultaneously determined and if so whether or not they are subject to

why don t we see poverty convergence average living standards are converging among developing countries and faster growing economies see more progress against poverty yet we do not find poverty convergence countries starting with higher poverty rates do not see higher proportionate rates of poverty reduction the paper tries to explain why analysis of a new dataset suggests that at given mean consumption high initial poverty has an adverse effect on consumption growth and also makes growth less poverty reducing thus for many poor countries the growth advantage of starting out with a low mean is lost due to a high incidence of poverty jel d63 i31 i32 o15

aid and growth regressions this paper examines the relationship between foreign aid and growth in real gdp per capita as it emerges from simple augmentations of popular cross country growth specifications it is shown that aid in all likelihood increases the growth rate and this result is not conditional on good policy there are however decreasing returns to aid and the estimated effectiveness of aid is highly sensitive to the choice of estimator and the set of control variables when investment and human capital are controlled for no positive effect of aid is found yet aid continues to impact on growth via investment we conclude by stressing the need for more theoretical work before this kind of cross country regressions are used for policy purposes

is tolerance good or bad for growth we investigate how tolerance as measured by attitudes toward different types of neighbors affects economic growth in a sample of 54 countries unlike previous studies by richard florida and others we find that tolerance toward homosexuals is negatively related to growth for tolerance toward people of a different race we do not find robust results but the sign of the estimated coefficients is positive suggesting that inclusion of people irrespective of race makes good use of productive capacity we propose mechanisms to explain these divergent findings which clarify why different kinds of tolerance may be of different economic importance

towards supply chain sustainability economic environmental and social design and planning abstract costumers and governments are pressuring companies to become more sustainable however the lack of research on how to incorporate these issues makes this a challenging task to fill this gap a generic multi objective mathematical programming model for the design and planning of supply chains integrating the three dimensions of sustainability is presented the economic pillar of sustainability is addressed in this work considering the costs of the supply chain then recipe an environmental assessment methodology indicated in the literature and by the european commission as the most developed one currently available is for the first time applied to supply chain design optimization finally a social indicator appropriate to assess strategic decisions is proposed this social indicator considers the impact of social and political concerns on company s performance the relevance of this model as a decision support system is highlighted with its application to a real case study of a portuguese battery producer and distributor a set of strategies to select the best solution among the obtained optimal ones is presented results show that the model allows improvements in all the three dimensions of sustainability and offers important managerial insights
