the multi item single period problem with an initial stock of convertible units abstract this paper deals with the situation of a number of end items each facing uncertain demand in a single period of interest besides being able to purchase units of the end items there is also available a stock of units that can be converted into end items but at unit costs that depend on the specific end item efficient solution procedures are presented for two situations i where the end item demand distributions are assumed known illustrated for the case of normally distributed demand and ii a distribution free approach where only the first two moments of the distributions are assumed known computational results for a set of problems are presented

empirical study on the determinants of co2 emissions evidence from oecd countries this article empirically investigates the environmental kuznets curve ekc for co2 emissions in the cases of 11 oecd countries by taking into account the role of nuclear energy in electricity production the autoregressive distributed lag approach to cointegration is employed as the estimation method our results indicate that energy consumption has a positive impact on co2 emissions in most countries in the study however the impact of trade is not statistically significant the results provide evidence for the role of nuclear power in reducing co2 emissions only in some countries additionally although the estimated long run coefficients of income and its square satisfy the ekc hypothesis in finland japan korea and spain only finland s ekc turning point is inside the sample period of the study providing poor evidence in support of the ekc hypothesis

land consumption and income in italy a case of inverted ekc abstract the ekc hypothesis postulates that the relationship between economic growth and environmental deterioration is represented by an inverted u shaped function its validity has been questioned from several perspectives and a need for public policies has been expressed this paper uses a heuristic approach to analyze the relationship between per capita income and land consumption as proxied by the number of building permits issued by public authorities using data from the italian regions we run a panel data regression model to test whether the ekc hypothesis holds results confute it evidencing a u shaped relationship in the authors opinion the combined effect of market conditions lifestyle evolution and institutional and political factors have produced an adverse effect on environment on this basis the paper claims that when social and intergenerational aspects are involved a balanced mix of market policies and institutional architecture is needed

factors determining the location decisions of spanish mnes an analysis based on the investment development path on the basis of theoretical assumptions approached via the investment development path idp this study examines the most important factors for and against the location decisions in foreign direct investment taken by multinational enterprises considering host countries at very different stages of economic development latin american and european union countries we carry out different kinds of analysis on a sample of 103 firms belonging to a medium sized country that has recently achieved the status of developed country the results reveal that the importance that home country firm managers give to diverse location factors depends to a certain extent on the stage that each group of host countries has reached in the idp in line with prior research we find that firm managers consider mainly the group of factors associated with strategic asset seeking when deciding to locate their investments in the group of more developed countries european union in contrast our results show that when these firm managers choose the group of less developed countries latin america social and cultural factors play a more determinant role thus suggesting the importance of historical and cultural ties between the home and host countries

decoupling of emissions and gdp evidence from aggregate and provincial chinese data abstract we provide a comprehensive analysis of the relationship between greenhouse gas ghg emissions and gdp in china using both aggregate and provincial data the trend or kuznets elasticity is about 0 6 for china higher than that in advanced countries but below that of major emerging markets the elasticity is somewhat lower for consumption based emissions than for production based emissions providing mild evidence consistent with the pollution haven hypothesis the kuznets elasticity is much lower for the last three decades than for the three previous decades suggesting a longer term trend toward decoupling as china has become richer further evidence of this comes from provincial data richer provinces tend to have smaller kuznets elasticities than poorer ones in addition to the trend relationship we find that there is a cyclical relation also holding in china

technology structural change and bop constrained growth a structuralist toolbox the latin american structuralism las is a significant part of the heterodox tradition in the theory of long run growth with a focus on the problems of developing economies which started their industrialization process when other regions had already accumulated substantial technological capabilities the emergence of a centre periphery system posed specific problems to growth and distribution in laggard economies which las discusses in a systematic way in this paper we presented a simple model which firstly captures key insights of the las school such as the persistency of technological asymmetries and structural heterogeneity secondly it can be used to analyze the impacts of shocks and policies based on how they affect supply side and demand side parameters of the model thirdly it links more closely post keynesian macroeconomics based on the bop constraint with the evolutionary microeconomics concerned with the dynamics of learning lastly it can be used as a toolbox and a teachable model in the analysis of the interactions between structural change technological catching up and long run growth

pollution haven hypothesis revisited a comparison of the brics and mint countries based on vecm approach abstract the aim of this study is to investigate the existence of pollution haven hypothesis phh and test the casual relationship between inward foreign direct investment fdi and environmental pollutions as well as other potential influencing factors of environmental performance to this end a panel vector error correction model vecm and panel co integration test is conducted for two country groups the brics i e brazil russia india china and south africa and the mint i e mexico indonesia nigeria and turkey during 1982 2014 empirical results illustrate a bidirectional and positive causality between fdi inflows and gdp per capita for both groups implying a virtuous circle of fdi growth nexus more importantly both the brics and mint countries illustrate bidirectional and negative causality between fdi inflows and environmental pressures i e per capita energy consumption for brics and per capita carbon emissions for mint such findings indicate the pollution haven hypothesis does not stand in this case in addition it is also found that the opening degree of trade can be promoted by fdi inflows which has rarely been deeply analyzed in prior studies concluding remarks and policy suggestions are proposed in the last section

the impacts of transport energy consumption foreign direct investment and income on co2 emissions in asean 5 economies abstract in this study we incorporate new variables and assess the impact of transportation sector s energy consumption and foreign direct investment on co2 emissions for asean 5 economies using the cointegration and granger causality methods this study also attempts to validate the environmental kuznets curve ekc hypothesis our results reveal that the co2 emissions and their determinants are co integrated only in indonesia malaysia and thailand the long run elasticity estimation suggests that income and transport energy consumption significantly influence co2 emissions whereas fdi is not significant economic growth plays a greater role in contributing to co2 emission in asean 5 nonetheless we find that the inverted u shape ekc hypothesis is not applicable to the asean 5 economies especially in indonesia malaysia and thailand in the long run the bi directional causality between economic growth and co2 emissions is detected in indonesia and thailand while we find unidirectional causality running from gdp to co2 emissions in malaysia we also observe bi directional causality between transport energy consumption fdi and co2 emissions in thailand and malaysia as an immediate policy option controlling energy consumption in transportation sector may result in a significant reduction in co2 emissions however this may slow the process of economic growth in malaysia and indonesia alternatively we suggest policymakers to place more emphasis on energy efficient transportation system and policies to minimise fossil fuel consumption thus the quality of environment can be improved with less deleterious impact on economic growth

is aggregate domestic consumption spending adcs per capita determining co2 emissions in south africa a new perspective aggregate domestic consumption spending is one of the prime drivers of economic progress that facilitates the process of industrialization international trade and innovation but its effect on the environment remains underresearched this paper proposes a novel framework to explain the impact of aggregate domestic consumption spending per capita adcsp on carbon dioxide emissions co2e in south africa using the autoregressive distributed lag ardl technique the results indicated that the adcsp determines co2e in the short run sr and long run lr from adcsp to carbon intensity adcsp ci estimations it was observed that an increase 1 in adcsp increases co2e in both the lr 0 31 and sr 0 22 furthermore the nardl estimations showed that the lr effects of positive shocks in the adcsp on co2e are comparatively stronger than the sr effects the paper offers important policy implications for academics theorists and policymakers

correctly analysing the balance of payments constraint on growth the balance of payments constrained growth bpcg model provides an interesting hypothesis regarding economic growth the main implication is that world demand places the dominant constraint to which individual country growth adjusts i discuss this implication and argue that tests of the bpcg model have essentially been tests of the hypothesis that trade is balanced over the long run a plausible hypothesis but one that need not hold mainly through responses to world demand as transmitted via income elasticities i then discuss the role of relative prices and investment point out logical inadequacies in the traditional bpcg framework and suggest an alternative theoretical framework to investigate its robustness our theoretical and empirical explorations suggest that traditional tests of the bpcg model may be misleading including investment as a proxy for the capacity to export and addressing endogeneity issues for example noticeably weakens the influence of world demand the evidence presented contributes to reconciling evidence supporting the bpcg hypothesis with recent work that consistently finds an important role for the level of the real exchange rate and investment independently of world demand

the toxic intensity of industrial production global patterns trends and trade policy this paper exploits a newly developed data set to investigate recent changes in the international distribution of industrial pollution in particular the authors examine three issues 1 the relationship between the toxic intensity of industrial production and the level of economic development 2 the impact of oecd environmental regulation on global changes in toxic intensity and 3 the relationship between trade policy and the toxic intensity of industrial production in ldc s 10 refs

the effect of fdi on environmental emissions evidence from a meta analysis one important and frequently raised issue about foreign direct investment fdi is the potentially negative consequences for the environment the potential environmental cost due to increased emissions may undermine the economic gains associated with increases in fdi inflow although the literature is dominated with this adverse view of fdi on the environment there is also a possibility that fdi can contribute to a cleaner environment especially if fdi comes with green technologies and this creates spillovers for domestic industries theoretically the effect of fdi on the environment can be negative or positive to deal with the theoretical ambiguity about the fdi environment nexus many empirical studies have been conducted but their results only reinforce the controversy as they produce contrasting results we conduct a meta analysis of the effect of fdi on environmental emissions using 65 primary studies that produce 1006 elasticities our results show that the underlying effect of fdi on environmental emissions is close to zero however after accounting for heterogeneity in the studies we find that fdi significantly reduces environmental emissions results remain robust after disaggregating the effect for countries at different levels of development as well as for different pollutants

linking namea and input output for consumption vs production perspective analyses evidence on emission efficiency and aggregation biases using the italian and spanish environmental accounts we integrate input output and namea tables for spain and italy in 1995 2000 and 2005 in order to address the hot policy issue of sustainable consumption and production a comparison of production and consumption perspectives may have relevant policy implications we deal with the domestic technology assumption and primarily the aggregation bias that may result when calculating indirect emission using different sector aggregations in the analyses e g 16 30 50 extended input output analysis provides analyses of the emissions embodied in domestic consumption and domestic production by considering the structure of intermediate inputs and environmental efficiency in each production sector our empirical findings show that different sectoral aggregation significantly biases the amount of emissions for the consumption perspective though differently in the two countries italy surprisingly show consumption production ratios around or lower than one but in line with some major work at eu level our results thus suggest that special attention must be paid when interpreting the ee ioa of country estimated amounts of embodied emissions both in domestic final demand and those directly associated with the production sectors when the sectoral aggregation level has a low definition as considered in some recent similar studies

is there an ekc between economic growth and smog pollution in china new evidence from semiparametric spatial autoregressive models abstract although china has achieved rapid economic growth it suffers from severe smog conditions determining how to promote cleaner production and environmental sustainability is of great significance in clarifying the relationship between income and pollutants within an extension of the stochastic impacts by regression on population affluence and technology stirpat framework the effects of economic growth on pm2 5 contamination are explicitly investigated based on a recent large sample of 249 chinese cities in 2015 from a nonlinear spatial perspective this study marks the first attempt at comprehensively exploring the nexus between the selected variables and pm2 5 emissions using semiparametric spatial autoregressive models which overcome the misspecification issues of conventional parametric models to avoid the limitations of a single method this study also applies different estimation techniques such as the spatial lag model slm the spatial autoregressive model with spatial autoregressive disturbances sarar two stage least squares regression 2slsr quantile regression qr and nonparametric regression npr the results reveal that pm2 5 pollutants show strong positive characteristics of spatial spillover the results also suggest that there is a significant inverted u shaped relationship between economic growth and pm2 5 concentrations which confirms the environmental kuznets curve ekc hypothesis additionally the empirical findings highlight the influence that the population density industrialization urbanization and traffic development factors have on increasing pm2 5 emissions in contrast technological innovation and green coverage do not play important roles in reducing pm2 5 concentrations the distribution of pm2 5 concentrations displays apparent geographical features to provide an in depth understanding of these impacts marginal analysis is performed to distinguish the local and neighbouring effects of determinants on pm2 5 pollution

confronting the environmental kuznets curve t he environmental kuznets curve posits an inverted u relationship between pollution and economic development kuznets s name was apparently attached to the curve by grossman and krueger 1993 who noted its resemblance to kuznets s inverted u relationship between income inequality and development in the first stage of industrialization pollution in the environmental kuznets curve world grows rapidly because people are more interested in jobs and income than clean air and water communities are too poor to pay for abatement and environmental regulation is correspondingly weak the balance shifts as income rises leading industrial sectors become cleaner people value the environment more highly and regulatory institutions become more effective along the curve pollution levels off in the middle income range and then falls toward pre industrial levels in wealthy societies the environmental kuznets curve model has elicited conflicting reactions from researchers and policymakers applied econometricians have generally accepted the basic tenets of the model and focused on measuring its parameters their regressions typically fitted to cross sectional observations across countries or regions suggest that air and water pollution increase with development until per capita income reaches a range of 5000 to 8000 when income rises beyond that level pollution starts to decline as shown in the conventional ekc line in figure 1 in developing countries some policymakers have interpreted such results as conveying a message about priorities grow first then clean up numerous critics have challenged the conventional environmental kuznets curve both as a representation of what actually happens in the development process and as a policy prescription some pessimistic critics argue that crosssectional evidence for the environmental kuznets curve is nothing more than a

technological regimes catching up and leapfrogging findings from the korean industries abstract this paper examines the experiences of selected industries in korea to identify the stylized facts in the process of technological capability building and thereby to sort out the conditions for the catching up to occur to explain the process we have built a model of technological and market catching up a special attention has been given to the question of whether there has been a case of leapfrogging in any industry in korea and if so what are the conditions for its incidence in our framework we first measure the degree of catching up in terms of market shares in the world then we focus on catching up in technological capabilities in explaining the different record and prospects of korean industries in market catching up in the model technological capability is determined as a function of both technological effort and the existing knowledge base as determinants of technological effort we look at the technological regimes of the industries such as cumulativeness of technical advances fluidity predictability of technological trajectory and the properties of knowledge base using this model we explain the different technological evolution of the selected industries in korea including the d ram automobile mobile phone consumer electronics personal computer and machine tool industries we find three different patterns of catching ups path creating catching up cdma mobile phone path skipping catching up d ram and automobile and path following catching up consumer electronics personal computers and machine tools we interpret the first two case of catching up as leapfrogging unlike the argument by perez and soete perez c soete l 1988 catching up in technology entry barriers and windows of opportunity in dosi et al eds technical change and economic theory pinter publishers london we find that important r d projects except automobiles where only private r d was involved involved both private and public capacities and that entry was not driven by endogenous generation of knowledge and skills but by collaboration with foreign companies

accurate lead time demand modeling and optimal inventory policies in continuous review systems abstract to construct an accurate probability density function for lead time demand in inventory management models a mixture of polynomials mops distributions is estimated using b spline functions from empirical data on demand per unit time this is accomplished by summarizing the empirical observations into separate datasets for each lead time value a mixture distribution approach is then applied to model lead time demand in a continuous review inventory system inventory policies can be determined without knowledge of the underlying demand and or lead time distributions an improvement to a mixture distribution approach that models the lead time demand distribution with a mixture of truncated exponentials mtes distribution is also presented and the mop and mte techniques are compared both methods provide reasonable accuracy but the mop approach requires lower computational time to determine optimal inventory policies the mixture distribution approach is also compared with solutions calculated using optimization through simulation and by compiling a discrete empirical lead time demand distribution

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

a multiscale reassessment of the environmental kuznets curve for energy and co2 emissions abstract this paper investigates the environmental kuznets curve hypothesis for total primary energy supply and co2 from fuel combustion over the period 1971 2015 our analysis has two distinguishing features firstly it adopts a robustness approach by a using both parametric and semi parametric methods and b analysing different geographical scales secondly it strictly adheres to the ekc narrative by a not using control variables and b taking energy and co2 in absolute rather than in per capita terms which is consistent with the fact that nature cares about absolute pressures we show how evidence for ekc changes depending on the model specification the sample and the used variables hence this paper contributes to explaining why the literature on the ekc gives mixed results the multiscale perspective and some theoretical considerations however tell how to perform the analysis appropriately thus we can affirm that both for co2 and energy the fragile evidence of ekc that was emerging at the end of the last century has vanished with the new wave of globalization there is only evidence of decreasing elasticities for very high income countries interestingly the great recession might have produced structural reductions in tpes and co2 in the affected countries finally the case of germany which shows ekc patterns indicates that active energy policies can reduce energy and co2 without harming the economy

determinants of co2 emissions in a small open economy abstract the aim of the paper is to explore the relationship between economic development and carbon dioxide co2 emissions for a small open and industrialized country austria we test whether an environmental kuznets curve relationship also holds for a single country rather than concentrating on panel or cross section data for a set of countries a cubic i e n shaped relationship between gdp and co2 emissions is found to fit the data most appropriately for the period 1960 1999 and a structural break is identified in the mid seventies due to the oil price shock furthermore two variables are additionally significant import shares reflecting the well known pollution haven hypothesis and the share of the tertiary service sector of total production gdp accounting for structural changes in the economy emission projections derived from this single country specification support the widely held opinion that significant policy changes are asked for when implementing the kyoto protocol in order to bring about a downturn in future carbon emissions

energy consumption in china and underlying factors in a changing landscape empirical evidence since the reform period abstract in recent decades the phenomenal growth in the chinese economy has created increasing energy consumption this is the first study analysing energy consumption in china considering economic social and political dimensions of globalisation along with the effects from trade and financial sectors the time period covers the full trajectory since the start of economic reform until recent times in this respect we use the konjunkturforschungsstelle kof globalisation index to explore the dynamic link between economic growth financial development trade and various dimensions of globalisation and energy consumption modern time series econometric techniques are used in establishing stationarity long run dynamics and causality of the series the findings suggest that globalisation decreases energy consumption in the short run but increases it in the long run however the effect of financial development on energy consumption in china is opposite to the globalisation effect on energy consumption granger causality reveals a feedback effect between economic globalisation and financial development globalisation in china can only reduce energy consumption if china develops its financial sector to a greater extent in future china should invest in its financial sector and low carbon energy alternatives to achieve sustainable development prevention of energy shortfalls and cleaner environment would assist in bridging the gap both from social and political aspects to ensure china benefits significantly with high economic growth in this asian century

the environmental kuznets curve ekc theory part a concept causes and the co2 emissions case abstract the main purpose of this study is to capture the main features of the environmental kuznets curve ekc concept according to the ekc theory the process of economic growth is expected eventually to limit the environmental degradation created in the early stages of development the ekc concept leads many researchers from the early 1990s to assume that each economy should focus on its growth and any environmental problems will be eventually eliminated by the process of economic growth several studies attempt to test empirically the ekc hypothesis using data on many countries and examining various types of environmental degradation while other studies examine the underlying factors that may drive such a relationship this article reviews the evolution of the ekc concept and the possible causes of an ekc pattern like the distribution of income the international trade pollution haven hypothesis structural changes technical progress and improvements in energy efficiency institutions and governance and consumer preferences as co2 emissions are a pollutant with global effects several studies deal with the possible ekc pattern for co2 emissions and these studies are discussed separately the various critiques on the ekc concept are reviewed in the second article of this work

non renewable and renewable energy consumption and co2 emissions in oecd countries a comparative analysis abstract this paper attempts to explore the determinants of co 2 emissions using the stirpat model and data from 1980 to 2011 for oecd countries the empirical results show that non renewable energy consumption increases co 2 emissions whereas renewable energy consumption decreases co 2 emissions further the results support the existence of an environmental kuznets curve between urbanisation and co 2 emissions implying that at higher levels of urbanisation the environmental impact decreases therefore the overall evidence suggests that policy makers should focus on urban planning as well as clean energy development to make substantial contributions to both reducing non renewable energy use and mitigating climate change

integrated vendor buyer cooperative models with stochastic demand in controllable lead time abstract this article presents the single vendor single buyer integrated production inventory models we relax the assumption that lead time demand x is deterministic and assume that it is stochastic also we assume that shortage during the lead time is permitted and lead time can be reduced at an added cost two models are considered here in the first model the demand of lead time follows a normal distribution and in the second model it is distribution free for both cases we develop effective iterative procedures for finding the optimal policy and numerical examples are used to illustrate the benefits of integration

trade openness carbon emissions nexus the importance of turning points of trade openness for country panels abstract this paper explores the relationship between trade openness and co 2 emissions by incorporating economic growth as an additional and potential determinant of this relationship for three groups of 105 high middle and low income countries we apply the pedroni 1999 and westerlund 2007 panel cointegration tests and find that the three variables are cointegrated in the long run trade openness impedes environmental quality for the global high income middle and low income panels but the impact varies in these diverse groups of countries the panel vecm causality results highlight a feedback effect between trade openness and carbon emissions at the global level and the middle income countries but trade openness granger causes co 2 emissions for the high income and low income countries policy implications are also provided

robust inventory decision under distribution uncertainty a cvar based optimization approach abstract we study the robust inventory decision making problem faced by risk averse managers with incomplete demand information in a newsvendor setting three basic models are developed expected profit maximization cvar based profit maximization and a combination of the two each model is robustly formulated under the assumption of ellipsoid discrete distribution and again under the box discrete distribution each robust model can be mathematically transformed into a second order cone program for ellipsoid uncertainty or into a general convex optimization problem for box uncertainty both transformed problems can be optimally solved directly we offer propositions with proof to show the equivalence of the transformed problems with the original ones numerical examples are given to validate the proposed approach we find that the performances under both ellipsoid and box uncertain distributions are robust finally sensitivity analysis with respect to risk averse levels and trade off coefficients is conducted to validate the proposed models and solution approaches

transboundary effects of environmental policy markets and emission leakages abstract one of many explanations for environmental kuznets curves for rich countries can be that dirty production is relocated to economies with laxer abatement regimes if this is caused by national abatement policies environmental stresses are transferred to other countries further the economic costs of national abatement policies can be shared with foreigners to some extent both through a lower demand for imports and losses of market shares for foreign competitors that produce cleaner products we quantify effects internally and abroad of a growth induced unilateral carbon tax policy in a rich open economy we find that the environmental benefits fall and the economic costs rise when a global rather than a national perspective is employed

shaping the relationship between economic development and carbon dioxide emissions at the local level evidence from spatial econometric models the debate over the correlation between economic growth and environmental pollution has attracted a great deal of attention from academic researchers and policy makers in recent years there has been excessive use of spatial econometric models and too much emphasis on statistical procedures in empirical studies in this study we contribute to the existing literature by conducting a more rigorous analysis of the relationship between economic growth and hbox co 2 emissions in chinese cities using spatial durbin models our results show that hbox co 2 emissions increase monotonically in relation to economic growth at the city level and that the driving effects of economic growth are slightly smaller in central china than in eastern and western china in addition to economic growth industry s share of the economy is a major driver of hbox co 2 emissions while technological improvement measured by energy intensity per unit of gross domestic product gdp and the effectiveness of environmental governance flatten the shape of the environmental kuznets curve we provide evidence of local spillover effects of explanatory variables on hbox co 2 emissions economic competition as well as technological diffusion are found to exist in chinese cities in relation to hbox co 2 emissions we also find carbon leakage between cities only if the per capita gdp of a given city is less than 493 in 2010 constant dollars results hold when robustness checks are performed policy makers should carefully consider regional differences and the inherent spatial interactions between factors when formulating carbon reduction policies

economic growth sectoral structures and environmental methane footprints we analyze the impacts of economic growth on methane emissions per capita at the sectoral level for the period 1997 2014 we cover three stages of the supply chain distinguishing between emissions

improved quality setup cost reduction and variable backorder costs in an imperfect production process abstract this paper illustrates the relationship between quality improvement reorder point and lead time as affected by backorder rate in an imperfect production process to reduce the total system cost by optimizing the setup cost lot size lead time reorder point and process quality parameter simultaneously we first consider that the lead time demand follows a normal distribution then we apply the distribution free approach for the lead time demand we prove two lemmas which are used to find optimal solutions for the basic and distribution free models we compare our models with the existing models using numerical examples and show that significant savings over the existing models can be achieved

participation in gvcs and co2 emissions abstract this paper attempts to explore the determinants of co2 emissions in the context of international trade while there exist studies that examine the roles of horizontal specialization and inter industry trade transactions little previous research attention has been paid to the roles of vertical specialization and intra industry trade transactions in affecting co2 emissions to fill the knowledge gap this study uses the panel data of 62 countries and regions for the period of 1995 2011 to estimate the effect of participation in global value chains gvcs on per capita co2 emissions major findings include 1 the relationship between participation degrees in gvcs and per capita co2 emissions is found to be inversely u shaped at the aggregate economy level and for most individual industries 2 per capita gdp shows an n shaped relationship with per capita co2 emissions and 3 benign drivers of co2 emissions include r d energy conservation and population control it can be concluded that countries with low gdp or gvc participation degrees are expected to experience worsening co2 emissions in the short or even medium run this trend however can be moderated or even reversed with more r d investments

trade the pollution haven hypothesis and the environmental kuznets curve examining the linkages abstract this paper examines the extent to which the ekc inverted u relationship can be explained by trade and specifically the migration or displacement of dirty industries from the developed regions to the developing regions the pollution haven hypothesis phh using detailed data on north south trade flows for pollution intensive products the evidence for the phh is assessed emissions of 10 air and water pollutants are then estimated controlling for trade openness structural change and dirty north south trade flows evidence of pollution haven effects is found although such effects do not appear to be widespread and appear to be relatively small compared to the roles played other explanatory variables

does urbanization increase pollutant emission and energy intensity evidence from some asian developing economies abstractthis paper aims to investigate the effects of urbanization on pollutant emissions and energy intensity in selected asian developing countries after controlling for the effects of disaggrega

carbon dioxide emissions and economic growth an assessment based on production and consumption emission inventories working with a new dataset on comparable global co2 production and consumption inventories spanning the 1997 2011 period we investigate the relationship between real gross domestic product gdp per capita and co2 emissions per capita associated with both production and consumption activities by including linkages between production based emissions in one country and final consumption in another via cross border value chains we focus on the entire carbon chain we estimate polynomial and threshold models accounting for reverse causality and identification problems we find that the income elasticity for both inventories is regime dependent and reflects small carbon efficiency gains from economic development carbon footprints show larger income elasticities while national policy instruments targeting production can clearly be circumvented by carbon embodied in intermediate trade this implies problems of environmental sustainability that may require consumption based policy instruments

carbon dioxide emissions and trade evidence from disaggregate trade data abstract the relationship between trade and environmental quality is a major controversial issue the paper intends to provide robust evidence and new insights into the discussion specifically it examines the effect of trade on carbon dioxide emissions co2 systematically in a north north north south south north and south south context it employs a panel data instrumental variable quantile approach to control for endogeneity and account for potential quantile parameter heterogeneity some important results emerge first trade with the north increases co2 emissions whereas trade with the south mitigates co2 emissions with a relatively larger effect for less polluted host countries second for advanced countries their trade with the south or the north leads to a reduction in co2 emissions the effect that seems relatively stronger for less polluted advanced countries third for developing countries their trade with the north worsens co2 emissions whereas their trade with the south mitigates co2 emissions with a larger effect for less polluted developing countries last the environmental kuznets hypothesis is also detected across quantiles for the full sample and both developing and advanced countries subsamples the findings suggest that trade benefits the advanced countries but could hurt the developing countries when trade with high income trading partners occurs in terms of co2 emissions

dynamics of export specialization in the regions of the italian mezzogiorno persistence and change guerrieri p and iammarino s 2007 dynamics of export specialization in the regions of the italian mezzogiorno persistence and change regional studies 41 933 947 during the 1980s and 1990s the italian southern economy displayed signs of transformation in production and export structures accompanied by sharp geographical differentiation debate on these changes mainly spurred by growing international pressure has given rise to different views and expectations on the opportunities for endogenous growth on the italian periphery the aim of this paper is to contribute to this ongoing debate by looking at the evolution of sectoral export specialization patterns i e relative comparative advantage structures in the mezzogiorno regions in the period 1985 2000 focusing on inter provincial comparisons the analysis concentrates on the extent of persistence versus change in the evolution of provincial specialization patterns shedding light on the relationship between export structure and performance

dirty industries patterns of change in industrial countries this article concerns itself with the environmental role of heavily polluting industries since 1970 analysing its development in 11 basic industries as well as electricity production and road transport in 32 industrial countries it argues for a green industrial policy demonstrating that other mitigations of environmental pressure in industrial countries end of pipe treatment relocation to the third world structural change in the industrial sector and even environmentally oriented modernization have so far been unable to solve the problems of dirty industries although some approaches have shown some promise

the environmental consequences of domestic and foreign investment evidence from china abstract fixed asset investment fai and foreign indirect investment fdi have important influences on economic development and environmental quality because environmental performance is related with economic development fai and fdi may affect environment indirectly through their impacts on economic growth in this study the direct and indirect effects of both fai and fdi on china s environmental quality are distinguished and separately estimated for the first time with a carefully designed framework of a two equation model because most economic activities and environmental pollutions occur in the urban areas a panel data of 112 chinese cities for the period 2002 2015 is utilized several spatial factors are also introduced to control for the potential spatial correlations in economic development and pollutant emissions the estimation results indicate that there exist apparent differences in the environmental effects of fai and fdi the direct effects of fai on so 2 emissions are significant positive and dominate the negative indirect effects by contrast the direct indirect and total effects of fdi on pollutant emissions are all negative therefore overall speaking well designed and targeted policies should be formulated to reduce the negative environmental impacts of fai and to increase the positive influences of fdi on environment

public policies and the art of catching up matching the historical evidence with a multicountry agent based model in this paper we study the effects of industrial policies on international convergence using a multi country agent based model which builds upon dosi et al 2019b the model features a group of microfounded economies with evolving industries populated by heterogeneous firms that compete in international markets in each country technological change is driven by firms activities of search and innovation while aggregate demand formation and distribution follows keynesian dynamics interactions among countries take place via trade flows and international technological imitation we employ the model to assess the different strategies that laggard countries can adopt to catch up with leaders market friendly policies industrial policies targeting the development of firms capabilities and rd protectionist policies focusing on tariffs only we find that markets cannot do the magic in absence of government interventions laggards will continue to fall behind on the contrary industrial policies can successfully drive international convergence among leaders and laggards while protectionism alone is not necessary to support catching up and countries get stuck in a sort of middle income trap finally in a global trade war where developed economies impose retaliatory tariffs both laggards and leaders are worse off and world productivity growth slows down

a technology gap interpretation of growth paths in asia and latin america abstract this paper presents a north south technology gap model which combines the schumpeterian approach to technical and structural change with the keynesian perspective on effective demand and the balance of payments bop constraint as drivers of growth three are the contributions of the paper first it develops a model in which the technology gap relative productivity and relative wages co evolve and may generate different paths of convergence or divergence between south and north depending on the parameters of the model second the parameters of the model are associated with different types of policies which allows for discussing how these policies may change the growth path finally the model is used to discuss the contrasting experiences of asia and latin america since 1970 convergence in asia and divergence in latin america have been extensively debated topics in the literature on comparative economic development which highlights the crucial role of industrial policy it is argued that the results of the technology gap model are consistent with the findings of this literature and helps understand the forces behind convergence and divergence

minimax distribution free procedure with backorder price discount abstract the inventory models analyzed in this paper explore the problem in which the lead time and ordering cost reductions are inter dependent in the continuous review inventory model with backorder price discount the objective is to minimize total related cost by simultaneously optimizing the order quantity reorder point lead time and backorder price discount moreover we assume that the mean and variance of the lead time demand are known but its probability distribution is unknown we apply a minimax distribution free procedure to find the optimal solution and three numerical examples are given to illustrate the results

economic growth energy and environmental kuznets curve the aim of this study is to investigate the relationship between income and carbon dioxide co2 emissions in the context of the environmental kuznets curve ekc which posits the existence of an inverted u shape relationship between environmental degradation and economic development for this purpose two empirical models are examined for both models the relationship between per capita income and per capita co2 emissions and the relationship among per capita income per capita energy use and per capita co2 emissions are analyzed respectively between 1980 and 2010 using the panel data estimation techniques with the application of driscoll kraay standard errors yet for the first model data are analyzed for 26 oecd countries with high income levels while for the second model data are examined for 52 emerging countries the results of both models show that n shape and an inverted n shape relationship for cubic functional form are observed thus the results do not support the ekc hypothesis which implies that environmental degradation cannot be solved automatically by economic growth

sustainability in a post keynesian growth model for an open economy the paper expands the bop constraint growth model and kaldorian regimes productivity and demand regimes in order to include some of the concerns raised by ecological economics in post keynesian models for open economies the demand regime is modified by taking into account porter s hypothesis which suggests that environmental innovations spurred by environmental policies can foster competitiveness as a result the equilibrium bop constrained rate of growth increases leading to a different version of thirlwall s law which opens room for analyzing the impact of environmental innovations on convergence between developing and developed economies the productivity regime in turn considers the growth and employment implications of innovations in labor productivity standard innovations and environmental efficiency environmental innovations it is argued that the fiscal policy and composition of public expenditure matter for long run growth employment and sustainability

shifts in foreign trade competitiveness and growth potential from baltics to bal techs abstract the collapse of socialism and the ensuing transition process have revealed the position of estonia latvia and lithuania in an international economic perspective data presented in this paper suggest that the baltics are competitive in sectors that generate little value added as a result of their inferior level of technology relative to their trade partners mainly oecd europe this raises questions about the income levels attainable in these countries the question with respect to future economic growth is whether there is any potential in the baltic countries to increase the level of technology this paper argues that the socialist past especially the separation of research and development from production is an important obstacle to technological progress in the baltics in order to integrate research and production socialist institutions need to be transformed or abolished while new ones have to be created this will take considerable time and effort

international competitiveness in post keynesian growth theory controversies and empirical evidence a fundamental starting point for post keynesian theory concerning growth in open economies is succinctly expressed in the following statement by kaldor t he main autonomous factor governing both the level and the rate of growth of effective demand of an industrial country is the external demand for its exports and the main factor governing the latter is international competitiveness which in turn depends on the level of its industrial cost relatively to other industrial exporters kaldor 1971 p 7 italics added moreover thanks to increasing returns in manufacturing export expansion and international competitiveness would interact so as to create vicious or virtuous circles of cumulative causation a few years later kaldor having found a positive correlation between the time changes of the main industrial countries relative manufacturing export shares and that of their relative unit costs a correlation that became known as the kaldor paradox dismissed his original cumulative causation theory and adopted a version close to harrod s foreign trade multiplier the purpose of this paper is to reaffirm the kaldorian cumulative causation theory in its original version by providing a firmer analytical basis and showing that contrary to the kaldor paradox time changes in export performance must be explained by levels rather than by changes in unit costs

a test of environmental kuznets curve for haze pollution in china evidence from the penal data of 27 capital cities abstract the mounting environmental crisis especially the large scale and continuous haze pollution is the most pressing challenge for china during rapid urbanization process this study is aimed at examining the relationship between haze pollution and economic growth and its turning points for different regions in china based on the panel data of 27 capital cities and municipalities in china during 2011 2015 we constructed the parameter estimation model after conducting the unit root cointegration and hausman tests based on the basic and extended models we find that the relationship between haze pollution and economic growth in china is not a typical inverted u shaped environmental kuznet curve ekc by introducing variables such as industrial structure foreign trade and energy intensity this study demonstrates that adjusting industrial structure and improving energy efficiency are effective means for haze pollution control grouping regressions reveal that regional differences exist in the relationships between haze pollution and economic growth and their tuning points for instance there was a u shaped relationship for the central region while there were inverted n shaped relationships for eastern western and northeastern regions policy implications are thus summarized for different regions in terms of balancing economic growth and environmental protection

keeping up with the technology pace a dns curve and limit cycle in a technology investment decision problem abstract in order to keep up with its economic environment a firm should respond to new technological developments in this paper we establish the optimal technology investment decision within a dynamic model in which the baseline technology level rises over time the problem is analyzed by designing a two state optimal control model it turns out that in the state space a dechert nishimura skiba dns curve can be determined that separates different long run outcomes viz zero investment constant positive investment or a cyclical sequence of zero and positive investment

is the environmental kuznets curve hypothesis a sound basis for environmental policy in africa achieving economic development and environmental sustainability simultaneously is one of the most important development challenges for africa today the relationship between economic growth and environmental sustainability is founded on the environmental kuznets curve ekc this paper examines the validity of the hypothesis and the driving factors of carbon dioxide co2 emission in five african countries using the stirpat empirical model panel cointegration and fully modified ordinary least squares unlike previous studies economic development is disaggregated into agriculture and industrial economic development the results show that there is no evidence of the validity of the hypothesis in africa regardless of whether economic development is driven by agriculture or industrialisation energy structure and energy intensity are the two major driving forces of co2 emissions in africa population growth and urbanisation have negative relationship with co2 emissions from our results the ekc is not a sound basis for environmental policy in africa rather environmental policy in africa specifically for co2 emissions mitigation should focus on encouraging energy efficiency enhancing the use of clean energy incorporating the impact of population growth and harnessing the positive impacts of urbanisation

do countries influence neighbouring pollution a spatial analysis of the ekc for co2 emissions abstract by considering spatial relationships this study aims to analyse to what extent per capita co2 emissions are determined by renewable energy consumption the share of the services sector in gdp energy intensity and real per capita income a panel data set composed of 173 countries over the 1990 2014 period is used to estimate an environmental kuznets curve ekc augmented by neighbouring per capita income and energy intensity both standard and spatial forms are estimated for seven different sets of countries to assess the robustness of the results finally several forecasts are performed to verify global sustainability and to provide some policy suggestions for the period 2015 2100 the empirical results indicate that i most areas support the standard ekc ii there seems to be an inverted u shaped relationship between neighbouring per capita income and national per capita emissions in europe asia and the world as a whole iii neighbouring energy intensity increases national per capita emissions and iv forecasts show that economic growth will accelerate climate change however a steady annual growth in renewable energy consumption and a steady decrease in energy intensity both close to 2 5 may guarantee environmental sustainability prior to 2100

a further inquiry into the pollution haven hypothesis and the environmental kuznets curve abstract empirical research on the relationship between economic growth and its impact on the environment often tests the environmental kuznets curve ekc a hypothesis that rising national output leads to increases in pollution emissions until an economy reaches a certain size and decreases thereafter this paper addresses a branch of ekc literature focused on the role international trade plays in shaping this relationship in particular we test the pollution haven hypothesis which posits that emission reductions observed in developed nations are partly the result of shifting dirty production to developing nations with lax environmental standards we estimate ekcs for seven oft studied pollutants and find little evidence that pollution havens play a significant role in shaping the ekc we also find that confidence intervals around ekc turning points are very wide often including values well above the range of the data this leads us to be skeptical of the optimistic view that economic growth naturally leads to improvements in environmental quality

are asean countries havens for japanese pollution intensive industry in an era of closer worldwide economic integration the role that environmental regulations play in shaping a country s comparative advantage is greater than ever this has led to fears that dirty firms will relocate from developed to developing countries where environmental regulations may be less stringent the so called pollution haven hypothesis to date however there is little support for the existence of pollution havens despite anecdotal evidence and the theoretical predictions in this paper we employ a unique industry level dataset for japan and examine whether japanese industries have relocated production to their asean neighbours in response to the relative stringency of japanese environmental regulations not only do we find no evidence for pollution haven consistent behaviour but also some indication that the complex relationship between the characteristics of japanese dirty industries and environmental regulations may actually have reduced japanese outward fdi to the philippines

us environmental load displacement examining consumption regulations and the role of nafta abstract in light of concerns that structural changes to us production may not be accompanied by similar changes to us consumption this paper provides a detailed examination of us environmental load displacement over the period 1974 2001 the forces that drive such displacement are also examined with particular attention paid to the scale and composition of us consumption the share of imports in consumption the role of environmental regulations and the potential impact of nafta it is found that the usa as a whole has experienced environmental load displacement over the period under consideration with the extent of this displacement seeming to increase over the last decade it would appear to be the increasing scale of us trade that is increasing environmental load displacement indeed the composition of us imports and exports have become significantly cleaner over the period considered however although imports from mexico have grown more rapidly than exports to mexico no evidence is found to suggest that nafta is increasing displacement to mexico with regard to us domestic consumption patterns although they have become cleaner a greater share than ever is now met via imports sectoral pollution abatement costs are found to be a determinant of this increasing share of imports in domestic consumption

manufacturing energy use in eight oecd countries decomposing the impacts of changes in output industry structure and energy intensity this paper examines trends in manufacturing energy use in eight oecd countries decomposing the changes that occured between 1973 and 1987 into the effects of changes in aggregate manufacturing activity industry structure and energy intensities measured at the industry group level while manufacturing production grew in every country except the uk the rate of growth was variable from nation to nation structural change led to modest reductions in energy use in most countries although in norway structural change led to substantial growth in energy use the reduction in energy intensities was strikingly uniform across all nations ranging from 20 norway to 36 japan over the period of the analysis while other studies have used divisia decomposition techniques we use an alternative method based on laspeyres indices a comparison of the two techniques shows that they yield closely similar empirical results although the laspeyres approach is more easily interpreted while the interactions between changes in structure and intensity are arbitrarily assigned to the two factors by the divisia approach the lapeyres method yields interaction terms that explicitly account for such effects

continental national and sub national innovation systems complementarity and economic growth the purpose of this paper is to discuss the relevance of innovation systems to economic growth rates over the last two centuries the focus is on complementarity or lack of it between sub systems of society and on models of active learning in catching up economies the paper discusses variations in rates of growth of economic regions and the extent to which variations may be attributed to innovation systems the analysis is applied to britain in the 18th century the united states in the second half of the 19th century and the innovation systems of catching up countries in the 20th century
