environmental kuznets curve hypothesis in pakistan cointegration and granger causality abstract the paper is an effort to fill the gap in the energy literature with a comprehensive country study of pakistan we investigate the relationship between co2 emissions energy consumption economic growth and trade openness in pakistan over the period of 1971 2009 bounds test for cointegration and granger causality approach are employed for the empirical analysis the result suggests that there exists a long run relationship among the variables and the environmental kuznets curve ekc hypothesis is supported the significant existence of ekc shows the country s effort to condense co2 emissions and indicates certain achievement of controlling environmental degradation in pakistan furthermore we find a one way causal relationship running from economic growth to co2 emissions energy consumption increases co2 emissions both in the short and long runs trade openness reduces co2 emissions in the long run but it is insignificant in the short run in addition the change of co2 emissions from short run to the long span of time is corrected by about 10 yearly

the environmental kuznets curve and the role of coal consumption in india cointegration and causality analysis in an open economy abstract this study investigates the dynamic relationship between coal consumption economic growth trade openness and co2 emissions in case of india in doing so narayan and popp journal of applied statistics 2010 37 1425 1438 structural break unit test is applied to test the order of integration of the variables long run relationship between the variables is tested by applying the ardl bounds testing approach to cointegration developed by pesaran et al journal of applied econometrics 2001 16 289 326 the results confirm the existence of cointegration for long run between coal consumption economic growth trade openness and co2 emissions our empirical exercise indicates the presence of environmental kuznets curve ekc in long run as well as in short run coal consumption as well as trade openness contributes to co2 emissions the causality analysis reports the feedback hypothesis between economic growth and co2 emissions and same inference is drawn between coal consumption and co2 emissions moreover trade openness granger causes economic growth coal consumption and co2 emissions

the causality relationship between energy consumption and gdp in g 11 countries revisited abstract this paper explores whether energy conservation policies can be implemented in countries with the same level of development that is is restraining energy consumption without compromising economic growth feasible in all industrialized countries a new granger non causality testing procedure developed by toda and yamamoto 1995 journal of econometrics 66 225 250 is applied to re investigate the relationship if any between energy consumption and income in 11 major industrialized countries the results clearly do not support the view that energy consumption and income are neutral with respect to each other except in the case of the united kingdom germany and sweden where a neutral relationship is found bi directional causality in the united states and uni directional running from energy consumption to gdp in canada belgium the netherlands and switzerland are found this indicates that energy conservation may hinder economic growth in the latter five countries further the causality relationship appears to be uni directional but reversed for france italy and japan which implies that in these three countries energy conservation may be viable without being detrimental to economic growth

environmental efficiency of investments in renewable energy comparative analysis at macroeconomic level abstract this paper aims to bring into attention the concept of renewable energy investments efficiency and to study one of the three concepts related to it namely environmental efficiency of investments in renewable energy the analysis is undertaken at macroeconomic level for several countries in europe some of them are member states of european union and were observed over the period between 1990 and 2008 the method assumes the study of the econometric models based on kaya identity an equation widely used in studies regarding emissions trends and future emissions scenarios working with time series and cross sectional data a panel data approach is needed indicators like energy intensity co 2 intensity and gross domestic product per capita and per unit of investment are used as they establish a connection between effects and efforts a prerequisite for studying the efficiency a novelty of this research lies in the calculation of environmental efficiency index after an original method proposed by authors the findings of this analysis reveal that there are both countries with high and low environmental efficiency of investments in renewable energy

studying the relationship between economic growth co2 emissions and the environmental kuznets curve in venezuela 1980 2025 abstract this work tries to determine whether it is possible to stabilize co2 emissions under a rapid increase of gross domestic product in a medium term the paper is an effort to study in detail how changes in the driving forces of the economy affect co2 emissions we study the case of venezuela for the period 1980 2025 using the methodology proposed by robalino lopez et al 2014 2013 1 2 which is based on an extension of the kaya identity and on a gdp formation approach that includes the effect of renewable energies we test the environmental kuznets curve ekc 3 hypothesis in a coming future under different economic scenarios considering therefore not only past data but also projections for the coming years we use cointegration techniques 4 and the jaunky 2011 5 specification to test the fulfillment of the ekc hypothesis in venezuela our predictions show that venezuela does not fulfill the ekc hypothesis but however the country could be on the way to achieve environmental stabilization in the medium term this stabilization could be accomplished combining economic growth with increasing use of renewable energy appropriated changes in the energy matrix and in the productive sectoral structure

do individual preferences explain the environmental kuznets curve abstract some economists maintain the optimistic view that individual preferences of rich people eventually lead to a virtuous circle relationship between rising income and environmental degradation in this article i review some of the models that establish a relationship between individual preferences and environmental quality these models provide a basis for discussion of the key role played by two factors individual preferences and technology they do not however capture the distributive conflicts that occur between different social groups in the process of defining environmental policy neither do they provide a good basis for distinguishing between environmental costs caused by the decisions of particular consumers and those which affect the same consumers this point is related to the various manners in which environmental costs are displaced displacement often occurs within a country for current costs and is even clearer and more relevant when costs are transferred across a great distance or to a remote future in such cases there are few incentives to reduce consumption or alter its composition displacement moreover can become a strategy pursued more or less consciously for maintaining high and rising levels of consumption without dealing with the associated environmental costs

a probabilistic choice model for market segmentation and elasticity structure marketing scholars commonly characterize market structure by studying the patterns of substitution implied by brand switching though the approach is useful it typically ignores the destabilizing

an ideal point probabilistic choice model for heterogeneous preferences this paper presents a new ideal point probabilistic choice model unlike the model suggested by cooper and nakanishi cooper l g m nakanishi 1983 two logit models for external analysis of preferences psychometrika48 4 607 619 which attempts to capture choices via a single ideal point the proposed model though based on aggregate data allows for heterogeneity in preferences by estimating a distribution of ideal points the model accounts for substitutability among choice alternatives and alleviates one of the major sources for the violation of the independence from irrelevant alternatives property it is demonstrated that the final form of the model is a multinomial probit with a covariance matrix that depends on the relative position of the choice alternatives an empirical application is provided and the resulting parameters are compared to the distributions of ideal points and attribute weights obtained via linmap at the individual level and via both the logit and probit versions of the model proposed by cooper and nakanishi at the aggregate level

carbon dioxide emissions and economic growth panel data evidence from developing countries in this paper we test the environment kuznet s curve ekc hypothesis for 43 developing countries we suggest examining the ekc hypothesis based on the short and long run income elasticities that is if the long run income elasticity is smaller than the short run income elasticity then it is evident that a country has reduced carbon dioxide emissions as its income has increased our empirical analysis based on individual countries suggests that jordan iraq kuwait yemen qatar the uae argentina mexico venezuela algeria kenya nigeria congo ghana and south africa approximately 35 per cent of the sample carbon dioxide emissions have fallen over the long run that is as these economies have grown emissions have fallen since the long run income elasticity is smaller than the short run elasticity we also examine the ekc hypothesis for panels of countries constructed on the basis of regional location using the panel cointegration and the panel long run estimation techniques we find that only for the middle eastern and south asian panels the income elasticity in the long run is smaller than the short run implying that carbon dioxide emission has fallen with a rise in income

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

testing predicted choices against observations in probabilistic discrete choice models probabilistic discrete choice models such as multinomial logit models are widely used to predict changes in market shares or total demand resulting from changes in policy variables under management control these models often are evaluated in terms of their ability to predict choices in a holdout sample this paper presents a new test for comparing predicted and observed choices the results of a monte carlo experiment indicate that the new test has good finite sample properties and high power in several circumstances likely to arise frequently in applications

environmental kuznets curve for co2 emissions the case of arctic countries abstract the main new contribution of this paper is to examine the environmental kuznets curve ekc hypothesis using time series data at individual country levels empirical focus is on the assessment of income per capita on co 2 emissions in the arctic countries by taking into account the role of energy consumption an autoregressive distributed lag ardl modeling approach to cointegration is applied to annual data for the period 1960 2010 the results provide little evidence of the existence of the ekc hypothesis for the arctic countries we also find that economic growth has a beneficial effect on the environment only in some arctic countries finally energy consumption is found to have a detrimental effect on the environment in most countries

on a clear day you might see an environmental kuznets curve we shed some new light on the environmental kuznets curve ekc and show how it can be viewed as a particular form of equilibrium relationship where technology and preference parameters determine the shape of the curve in contrast to most of the literature on the ekc we estimate a theoretically consistent model on long run data swedish sulfur emission covering the period 1900 2002 furthermore we test and date structural change the model suggests four regimes 1900 1918 1919 1933 1934 1967 and 1968 2002 generating four rather different patterns for pollution over time the policy conclusions are consonant with pearce s general view about the ekc there is no theoretical presumption that it has an inverted u shape nor should any country try to grow out of the environmental problems without analyzing the benefits and costs of so doing

the impact of economic growth on co2 emissions in azerbaijan abstract this paper investigates the relationship between the economic growth and co2 emissions in azerbaijan a cointegration analysis is conducted over the period 1992 2013 for getting more robust results johansen ardlbt dols fmols and ccr methods are employed to explore cointegration and estimate long run coefficients we use cubic quadratic and linear specifications and conclude that the last one is an adequate representation for the impact of the economic growth on co2 emissions in azerbaijan the results from the different cointegration methods are consistent with each other and show that the economic growth has a positive and statistically significant impact on the emissions in the long run implying that the ekc hypothesis does not hold for azerbaijan the income elasticity of co2 emissions using different methods is found to be between 0 7 and 0 8 moreover we find that any short run imbalance can be adjusted towards the long run equilibrium path within less than one year the paper concludes that measures to increase energy efficiency carbon pricing instruments in production and international domestic trade activities and nationwide social awareness programs to instruct about the negative consequences of pollution can be considered as relevant environmental policies aimed at reducing carbon emissions

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

using neoclassical consumer choice theory to produce a market map from purchase data this article presents a new model for estimating the spatial representation of objects and preference vectors from actual choice behavior of individuals or households it is based on neoclassical economic theory of consumer choice the model integrates both decisions of which good s to buy and the quantity of purchase overall preference is decomposed into price effects and intrinsic preference for the good a maximum likelihood method for estimating the model parameters is described and illustrated using choice data of ketchup brands collected by the use of electronic supermarket scanners

further evidence of an environmental kuznets curve in spain abstract using a long span of data in spain esteve and tamarit 2012b reported evidence of a strong link between per capita income and per capita co2 in this paper we extend their work finding evidence of both non linear cointegration and asymmetric adjustment using a novel approach due to sephton 1994 and sephton and mann 2012 the results suggest that there is a long run non linear attractor drawing per capita income and co2 levels together with asymmetric adjustment

on the relationships between co2 emissions energy consumption and income the importance of time variation abstract the environment that governs the relationships between energy consumption carbon dioxide co2 emissions and gross domestic product gdp in the g7 countries changes over time due to variations in economic growth regulatory policy and technology using a novel approach that may detect causalities when the time constant hypothesis is rejected we find significant time varying granger causalities among the variables under consideration there is bidirectional causality between gdp and energy consumption for japan unidirectional causality running from gdp to energy consumption for italy and unidirectional causality running from energy consumption to gdp for the resource country canada moreover the results also show a bidirectional time varying causality between energy consumption and co2 emissions for the united states and causality from energy consumption to co2 emissions for france finally while we find significant time varying causalities running from gdp to co2 emissions for italy and japan the finding of inverted n shaped curves italy and japan lends no support to the traditional environmental kuznets curve ekc hypothesis for these countries it implies that environmental policy and economic growth should go hand in hand other policy implications of the empirical results have been proposed

energy consumption and economic growth in the next 11 countries the bootstrapped autoregressive metric causality approach abstract departing from previous literature using bootstrapped autoregressive metric causality approach which is more robust against non stationarity and break problems than lag augmented tests this study analyzes causal relation between economic growth and energy consumption in the next 11 countries estimating a trivariate model consisting of gdp per capita energy consumption per capita and gross capital formation it was found that the neutrality hypothesis is valid for all of the countries except for turkey these findings imply that energy conservation oriented policies should be implemented in bangladesh egypt indonesia iran korea mexico pakistan and philippines in the case of turkey a unidirectional causal nexus was found from energy consumption to economic growth since the growth hypothesis is valid energy conservation policy poses an obstacle for economic growth in turkey

investigating the environmental kuznets curve hypothesis in vietnam this study investigates the existence of the environmental kuznets curve ekc hypothesis in vietnam during the period 1981 2011 to realize the goals of this study a pollution model was established applying the autoregressive distributed lag ardl methodology the results revealed that the pollution haven hypothesis does exist in vietnam because capital increases pollution in addition imports also increase pollution which indicates that most of vietnam s imported products are energy intensive and highly polluted however exports have no effect on pollution which indicates that the level of exports is not significant enough to affect pollution moreover fossil fuel energy consumption increases pollution while renewable energy consumption has no significant effect in reducing pollution furthermore labor force reduces pollution since most of vietnam s labor force is in the agricultural and services sectors which are less energy intensive than the industrial sector based on the obtained results the ekc hypothesis does not exist because the relationship between gdp and pollution is positive in both the short and long run

the nexus of electricity consumption economic growth and co2 emissions in the brics countries abstract this study reexamines the causal link between electricity consumption economic growth and co 2 emissions in the brics countries i e brazil russia india china and south africa for the period 1990 2010 using panel causality analysis accounting for dependency and heterogeneity across countries regarding the electricity gdp nexus the empirical results support evidence on the feedback hypothesis for russia and the conservation hypothesis for south africa however a neutrality hypothesis holds for brazil india and china indicating neither electricity consumption nor economic growth is sensitive to each other in these three countries regarding the gdp co 2 emissions nexus a feedback hypothesis for russia a one way granger causality running from gdp to co 2 emissions in south africa and reverse relationship from co 2 emissions to gdp in brazil is found there is no evidence of granger causality between gdp and co 2 emissions in india and china furthermore electricity consumption is found to granger cause co 2 emissions in india while there is no granger causality between electricity consumption and co 2 emissions in brazil russia china and south africa therefore the differing results for the brics countries imply that policies cannot be uniformly implemented as they will have different effects in each of the brics countries under study

a single ideal point model for market structure analysis computing unsegmented product maps from preference data by means of single ideal point models is commonly thought to be impossible because of indeterminacy problems the authors show that this math

do economic financial and institutional developments matter for environmental degradation evidence from transitional economies abstract several studies have examined the relationship between environmental degradation and economic growth however most of them did not take into account financial developments and institutional quality moreover stern stern d 2004 the rise and fall of the environmental kuznets curve world development 32 8 1419 1439 noted that there are important econometric weaknesses in the earlier studies such as endogeneity heteroscedasticity omitted variables etc the purpose of this paper is to fill this gap in the literature by investigating the linkage between not only economic development and environmental quality but also financial development and institutional quality we employ the standard reduced form modelling approach to control for country specific unobserved heterogeneity and gmm estimation to control for endogeneity our study considers 24 transition economies and panel data for 1993 2004 our results support the ekc hypothesis while confirming the importance of both institutional quality and financial development for environmental performance we also found that financial liberalization may be harmful for environmental quality if it is not accomplished in a strong institutional framework

market boundaries and product choice illustrating attraction and substitution effects what happens to the share of choices each item receives when the choice set boundaries are extended by adding a new item that is extremely good on one dimension but poor on the others first there is a substitution effect whereby the new item takes choice share mainly from similar items in the set second there is an attraction effect resulting in a general shift of preference toward the added item experimental studies show that choice patterns conflict with current theoretical and common sense ideas about the effect of added alternatives on choice

choice map inferring a product market map from panel data this paper describes choice map a model that infers a product market map from panel data choice map is a stochastic brand choice model a random utility quantal choice model and a multidimensional scaling procedure choice map combines the parsimony of stochastic choice models the rationale of random utility models and the ability of multidimensional scaling procedures to simultaneously infer both brand positions and consumer preferences from preference choice data choice map assumes that consumers have stationary purchase probabilities for the observational period which makes the model best suited to frequently bought mature product categories neither experimental nor survey data are required traditional mapping methods that scale such data may not yield the same structure for low involvement products as will a procedure like choice map that scales behavioral data choice map s descriptive and predictive validity exceeds that of an alternative stochastic brand choice model the dirichlet multinomial for a test data set

time varying analysis of co2 emissions energy consumption and economic growth nexus statistical experience in next 11 countries this paper detects the direction of causality among carbon dioxide co2 emissions energy consumption and economic growth in next 11 countries for the period 1972 2013 changes in economic energy and environmental policies as well as regulatory and technological advancement over time cause changes in the relationship among the variables we use a novel approach i e time varying granger causality and find that economic growth is the cause of co2 emissions in bangladesh and egypt economic growth causes energy consumption in the philippines turkey and vietnam but the feedback effect exists between energy consumption and economic growth in south korea in the cases of indonesia and turkey we find the unidirectional time varying granger causality running from economic growth to co2 emissions thus validates the existence of the environmental kuznets curve hypothesis which indicates that economic growth is achievable at the minimal cost of environment the paper gives new insights for policy makers to attain sustainable economic growth while maintaining long run environmental quality

economic growth and environmental degradation the environmental kuznets curve and sustainable development abstract in this paper we critically examine the concept of the environmental kuznets curve ekc it proposes that there is an inverted u shape relation between environmental degradation and income per capita so that eventually growth reduces the environmental impact of economic activity the concept is dependent on a model of the economy in which there is no feedback from the quality of the environment to production possibilities and in which trade has a neutral effect on environmental degradation the actual violation of these assumptions gives rise to fundamental problems in estimating the parameters of an ekc the paper identifies other econometric problems with estimates of the ekc and reviews a number of empirical studies the inference from some such ekc estimates that further development will reduce environmental degradation is dependent on the assumption that world per capita income is normally distributed when in fact median income is far below mean income we carry out simulations combining ekc estimates from the literature with world bank forecasts for economic growth for individual countries aggregating over countries to derive the global impact within the horizon of the bank s forecast 2025 global emissions of so 2 continue to increase forest loss stabilizes before the end of the period but tropical deforestation continues at a constant rate throughout the period

co2 emissions energy consumption and economic growth in turkey abstract this paper examines the long run and causal relationship issues between economic growth carbon emissions energy consumption and employment ratio in turkey by using autoregressive distributed lag bounds testing approach of cointegration empirical results for turkey over the period 1968 2005 suggest an evidence of a long run relationship between the variables at 5 significance level in turkey the estimated income elasticity of carbon emissions per capita is 0 606 and the income elasticity of energy consumption per capita is 1 375 results for the existence and direction of granger causality show that neither carbon emissions per capita nor energy consumption per capita cause real gdp per capita but employment ratio causes real gdp per capita in the short run in addition ekc hypothesis at causal framework by using a linear logarithmic model is not valid in turkish case the overall results indicates that energy conservation policies such as rationing energy consumption and controlling carbon dioxide emissions are likely to have no adverse effect on the real output growth of turkey

inequality in co2 emissions across countries and its relationship with income inequality a distributive approach this paper analyses the inequality in co2 emissions across countries and groups of countries and the relationship of this inequality with income inequality across countries for the period 1971 1999 the research employs the tools that are usually applied in income distribution analysis the methodology used here gives qualitative and quantitative information on some of the features of the inequalities across countries that are considered most relevant for the design and discussion of policies aimed at mitigating climate change the paper studies the relationship between co2 emissions and gdp and shows that income inequality across countries has been followed by an important inequality in the distribution of emissions this inequality has diminished mildly although the inequality in emissions across countries ordered in the increasing value of income inequality between rich and poor countries has diminished less than the simple inequality in emissions lastly the paper shows that the inequality in co2 emissions is mostly explained by the inequality between groups with different per capita income level the importance of the inequality within groups of similar per capita income is much lower and has diminished during the period especially in the low middle income group

environmental kuznet s curve for india evidence from tests for cointegration with unknown structuralbreaks this study revisits the cointegrating relationship between carbon emission energy use economic activity and trade openness for india using threshold cointegration tests with a view to testing the environmental kuznet s curve hypothesis in the presence of possible regime shift in long run relationship of the variables for the period 1971 to 2008 the article confirms the existence of regime shift or threshold cointegration among the variables and environmental kuznet s curve for india it challenges previous empirical works for india which fail to establish cointegrating relationship among these variables and explains its logical and econometric reasons the study finds that the carbon emission is highly elastic with respect to real per capita income and energy use in india this finding is critical and warns successful design and execution of energy and environmental policy framework which would pave the low carbon sustainable growth path inindia

environmental kuznets curve for carbon emissions in pakistan an empirical investigation this study investigates the relationship between carbon emissions income energy consumption and foreign trade in pakistan for the period 1972 2008 by employing the johansen method of cointegration the study finds that there is a quadratic long run relationship between carbon emissions and income confirming the existence of environmental kuznets curve for pakistan moreover both energy consumption and foreign trade are found to have positive effects on emissions the short run results have however denied the existence of the environmental kuznets curve the short run results are unique to the existing literature in the sense that none of the long run determinants of emissions is significant the contradictory results of short and long run give policy makers the opportunity to formulate different types of growth policies for the two terms taking environmental issues into consideration in addition the uni directional causality from growth to energy consumption suggests that the policy makers should not only focus on forecasting future demand for energy with different growth scenarios but also on obtaining the least cost energy furthermore the absence of causality from emissions to growth suggests that pakistan can curb its carbon emissions without disturbing its economic growth

import demand of crude oil and economic growth evidence from india abstract this study establishes a long run equilibrium relationship among quantity of crude oil import income and price of the imported crude in india for the time span 1970 1971 to 2005 2006 using autoregressive distributed lag ardl bounds testing approach of cointegration empirical results show that the long term income elasticity of imported crude in india is 1 97 and there exists a unidirectional long run causality running from economic growth to crude oil import so reduction of crude oil import will not affect the future economic growth in india in the long run india should take various energy efficiency and demand side management measures in transport sector along with other measures like expanding and strengthening indigenous resource base substituting imported fuels by domestic fuels and de controlling the price of petroleum products to reduce its import dependence

determining the appropriate depth and breadth of a firm s product portfolio abstract some firms have broad product lines others have lean product lines to determine the appropriate number of entries in a specific firm s product line the author develops a model that balances the benefits of increased revenue from a broad product line against production and engineering costs two innovations were central in the development of the model 1 redefining how products are scored on various product attributes so that attribute scores vary normally across the population of products and 2 redefining how the number of entries in a product portfolio is calculated in order to discount the significance of entries that are highly similar to existing products the author also introduces the notion of a centroid time to more easily adjust sales and total development costs for product life cycle and investment life cycle effects these redefinitions enable a firm s profit to be modeled as a simple function of its effective number of product entries the effective number of competitors entrie

energy consumption and economic growth nexus in portugal italy greece spain and turkey an ardl bounds test approach 1965 2009 abstract the paper examines the nexus between primary energy consumption and growth in portugal italy greece spain and turkey pigst with annual time series data from 1965 to 2009 pigst are southern european economies which have experienced several episodes that make them of particular interest to the study of periods of economic expansion and stagnation an ardl bounds test approach is a suitable technique to examine energy growth nexus within the context of countries with both sporadic shocks outliers and permanent shocks structural breaks empirical results suggest bidirectional causality between energy and growth in both the long run and short run supporting the feedback hypothesis the results reveal themselves to be robust to panel framework an energy conservation policy will reduce gdp growth while a saving phenomenon is observed since one additional unit of product requires less than one unit of energy

carbon dioxide emission and income a temporal analysis of cross country distributional patterns the existence of a cointegrating relationship between income and co2 emission for individual country groups suggests existence of a corresponding relationship between the inter country disparities in the levels of income and co2 emission this paper explores the relationship between the patterns of cross country distribution of income and co2 emission and temporal shifts in such a relationship this paper also examines how the mean level of per capita co2 emission and its distributional inequality are related to the corresponding mean income level and the distributional inequality of income the analysis is based on a cross country panel data set at the level of country group environmental quality demanded is treated as a private good and not as a public good as done in most other studies the technique of lorenz and specific concentration curve analysis are used as the basic analytical framework to argue that a measure of relative distributional inequality of income should be used as an explanatory variable in the environmental kuznets curve ekc relationship along with the mean income level in the empirical exercise johansen s cointegration analysis technique is used to explore existence of statistically significant cointegrating vector s relating mean level of emission and specific concentration ratio scr of emission to mean income level and lorenz ratio lr of income the empirical results confirm that the pattern of cross country income distribution has significant effect on the mean level of emission for all the country groups considered

economic growth energy consumption financial development international trade and co2 emissions in indonesia this study examines the linkages among economic growth energy consumption financial development trade openness and co2 emissions over the period of 1975q1 2011q4 in the case of indonesia the stationary analysis is performed by using zivot andrews structural break unit root test and the ardl bounds testing approach for a long run relationship between the series in the presence of structural breaks the causal relation between the concerned variable is examined by the vecm granger causality technique and robustness of causal analysis is tested by innovative accounting approach iaa our results confirm that the variables are cointegrated it means that the long run relationship exists in the presence of structural break stemming in the series the empirical findings indicate that economic growth and energy consumption increases co2 emissions while financial development and trade openness compact it the vecm causality analysis has shown the feedback hypothesis between energy consumption and co2 emissions economic growth and co2 emissions are also interrelated i e bidirectional causality financial development granger causes co2 emissions the study opens up a new policy insights to control the environment from degradation by using energy efficient technologies financial development and trade openness can also play their role in improving the environmental quality

economic models for the environmental kuznets curve a survey abstract the environmental kuznets curve ekc refers to an inverted u shaped relationship between some pollutant level and per capita income i e the environmental quality deteriorates at early stages of economic growth and subsequently improves at a later stage since the early 1990s a considerable number of empirical studies have been conducted on the ekc and although there is no conclusive proof it has been recognized that the ekc emerges as an empirical regularity however some recent studies cast doubt on the concept and methodology of empirical results and evidence of the existence of the ekc has been questioned in fact how economic growth affects the environmental quality i e the shape of the ekc is still controversial in order to identify the actual relationship between the environmental quality and economic growth it is essential to develop economic models from various points of view this paper overviews the current stage of theoretical models that explain such relationship

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

social capital and co2 emission output relations a panel analysis the present paper examines the mitigating effect of social capital on the environmental kuznets curve ekc for co2 emissions using a panel data of 69 developed and developing countries adopting generalised method of moments gmm estimators the paper finds evidence substantiating the presence of ekc moreover the evidence suggests that the pollution costs of economic development tend to be lower in countries with higher social capital reservoir surprisingly there is also evidence to indicate that the income threshold point beyond which co2 emissions decline is higher in countries with higher social capital these results are robust to addition of alternative controlled variables in the ekc specification thus in addition to policy focus on investments in environmentally friendly technology and on the use of renewable energy investments in social capital can also mitigate the pollution effects of economic progress

energy consumption and gdp in tunisia cointegration and causality analysis abstract in this paper the johansen cointegration technique is used to examine the causal relationship between per capita energy consumption pcec and per capita gross domestic product pcgdp for tunisia during the 1971 2004 period in order to test for granger causality in the presence of cointegration among the variables a vector error correction model vecm is used instead of a vector autoregressive var model our estimation results indicate that the pcgdp and pcec for tunisia are related by one cointegrating vector and that there is a long run bi directional causal relationship between the two series and a short run unidirectional causality from energy to gross domestic product gdp the source of causation in the long run is found to be the error correction terms in both directions hence an important policy implication resulting from this analysis is that energy can be considered as a limiting factor to gdp growth in tunisia conclusions for tunisia may also be relevant for a number of countries that have to go through a similar development path of increasing pressure on already scarce energy resources

testing competitive market structures an accurate understanding of the structure of competition is important in the formulation of many marketing strategies for example in new product launch product reformulation or positioning decisions the strategist wants to know which of his competitors will be most affected and hence most likely to respond many marketing science models have been proposed to identify market structure in this paper we examine the managerial problem and propose a criterion by which to judge an identified market structure basically our criterion is a quantification of the intuitive managerial criterion that a submarket is a useful conceptualization if it identifies which products are most likely to be affected by our marketing strategies we formalize this criterion within the structure of classical hypothesis testing so that a marketing scientist can use statistical statements to evaluate a market structure identified by 1 behavioral hypotheses 2 managerial intuition or 3 market structure identification algorithms mathematically our criterion is based on probabilities of switching to products in the situation where an individual s most preferred product is not available submarkets are said to exist when consumers are statistically more likely to buy again in that submarket than would be predicted based on an aggregate constant ratio model for example product attributes e g brand form size use situations e g coffee in the morning versus coffee at dinner and user characteristics e g heavy versus light users are specified as hypotheses for testing alternate competitive structures measurement and estimation procedures are described and a convergent approach is illustrated an application of the methodology to the coffee market is presented and managerial implications of six other applications are described briefly

energy consumption carbon emissions and economic growth nexus in bangladesh cointegration and dynamic causality analysis abstract the paper investigates the possible existence of dynamic causality between energy consumption electricity consumption carbon emissions and economic growth in bangladesh first we have tested cointegration relationships using the johansen bi variate cointegration model this is complemented with an analysis of an auto regressive distributed lag model to examine the results robustness then the granger short run the long run and strong causality are tested with a vector error correction modelling framework the results indicate that uni directional causality exists from energy consumption to economic growth both in the short and the long run while a bi directional long run causality exists between electricity consumption and economic growth but no causal relationship exists in short run the strong causality results indicate bi directional causality for both the cases a uni directional causality runs from energy consumption to co 2 emission for the short run but feedback causality exists in the long run co 2 granger causes economic growth both in the short and in the long run an important policy implication is that energy electricity as well can be considered as an important factor for the economic growth in bangladesh moreover as higher energy consumption also means higher pollution in the long run policy makers should stimulate alternative energy sources for meeting up the increasing energy demand

energy conservation policies growth and trade performance evidence of feedback hypothesis in pakistan this study investigates the relationship between energy consumption and trade openness in pakistan by using the annual time series data for the period of 1973 2011 our main results show i the presence of long run link between energy consumption and trade performance ii positive impact of gross domestic product exports and imports on energy consumption iii bidirectional causal relationship between exports and energy consumption and also be tween imports and energy demand and iv bidirectional causality between gross domestic product and energy consumption points to the presence of feedback hypothesis in pakistan we therefore note that energy conservation policies will reduce the trade performance which in turn leads to the decline in economic growth in pakistan the present study may guide policymakers in formulating a conclusive energy and trade policies for sustainable growth for long span of time

modeling the evolutionary nexus between carbon dioxide emissions and economic growth abstract given the fast paced world economy increasing carbon dioxide co2 emissions have caused serious concern regarding global warming many studies have examined the nexus between co2 emissions and economic growth and inconsistent results are provided limited evidence suggests that different time periods under investigation could be a source of inconsistency but there lacks of a thorough analysis this paper systematically focuses on the evolutionary characteristics of the nexus to explore the influence of time periods the panel data are reorganized by considering different time periods in various countries and an intelligent data driven approach symbolic regression is applied to discover models for each period without predefined structure and parameters three issues does the time period matter what are the trends in different time periods what are the applicable scopes of the models have been addressed in this paper the results reveal the evolutionary nature of the nexus and it is verified that an intrinsic time period distinction does generate extrinsic inconsistency the detailed dynamics of models indicate that the optimal models tend to be more complex as the time periods are extended for countries with different locations and income levels the applicable scopes of the four superior models monotonically increasing inverted u shaped inverted n shaped and m shaped vary in different time periods the findings highlight that the effect of time periods cannot be ignored and the models should not be applied unconditionally when conducting empirical research finally several policy implications are provided which are critical for the balance of economic growth and co2 emissions particularly in some developing countries

dynamic modeling of causal relationship between energy consumption co2 emissions and economic growth in india abstract the paper investigates the causality relationships among energy consumption carbon dioxide co2 emissions and income in india using a dynamic modeling approach the paper also utilises an innovation accounting method to investigate profiles of the macroeconomic variables persisting from an unanticipated shock in innovation our results provide evidence of the existence of bi directional granger causality between energy consumption and co2 emissions in the long run but neither co2 emissions nor energy consumption causes movements in real income there is no causality relationship between energy consumption and income in any direction in the long run implying that india could follow energy conservation and efficiency improvement policies without impeding economic growth this will allow india to reduce co2 emissions without affecting its economic growth and contribute significantly towards combating global warming as well

the co2 emissions income nexus evidence from rich countries the paper attempts to test the environment kuznets curve ekc hypothesis for 36 high income countries for the period 1980 2005 the test is based on the suggestion of narayan and narayan 2010 various panel data unit root and co integration tests are applied carbon dioxide co2 emissions and gdp series are integrated of order one and co integrated especially after controlling for cross sectional dependence additionally the blundell bond system generalised methods of moments gmm is employed to conduct a panel causality test in a vector error correction mechanism vecm setting unidirectional causality running from real per capita gdp to per capita co2 emissions is uncovered in both the short run and the long run the empirical analysis based on individual countries provides evidence of an ekc for greece malta oman portugal and the united kingdom however it can be observed that for the whole panel a 1 increase in gdp generates an increase of 0 68 in co2 emissions in the short run and 0 22 in the long run the lower long run income elasticity does not provide evidence of an ekc but does indicate that over time co2 emissions are stabilising in the rich countries

impact of corruption in public sector on environmental quality implications for sustainability in brics and next 11 countries abstract this study investigates the impact of corruption in public sector on carbon emissions in presence of energy use segregation following the environmental kuznets curve ekc framework the study has been carried out for brazil russia india china south africa brics and next 11 countries over the period of 1990 2017 along with the finding of inverted n shaped ekc for both the cases we find that incidents of corruption enhance environmental degradation by reducing the positive impact of renewable energy consumption on environmental quality and increasing the negative impact of fossil fuel consumption this study has also divulged that the corruptive practices are more prone in case of the countries where the development is mature and institutionalization is more stringent based on these findings we suggest that environmental policies should take account of the corruption and thereby making the policies more robust and effective

bounds testing approach to analysis of the environment kuznets curve hypothesis abstract this paper examines the long run and the dynamic temporal relationships between economic growth energy consumption population density trade openness and carbon dioxide co 2 emissions in brazil china egypt japan mexico nigeria south korea and south africa based on the environment kuznets curve ekc hypothesis we employ the ardl bounds test to cointegration and cusum and cusumsq tests to ensure cointegration and parameter stability the estimated results show that the inverted u shaped ekc hypothesis holds in japan and south korea in the other six countries the long run relationship between economic growth and co 2 emissions follows an n shaped trajectory and the estimated turning points are much higher than the sample mean in addition the results indicate that energy consumption granger causes both co 2 emissions and economic growth in all the countries our results are consistent with previous studies that show that there is no unique relationship between energy consumption population density economic growth trade openness and the environment across countries

decomposition of co2 emissions over 1980 2003 in turkey abstract there is a multi dimensional need for studying the energy situation in turkey and to obtain insight into the development of co2 emissions on the one hand recent projections of the oecd show that turkey has a yearly gdp growth potential of over 7 on the other hand recent projections of undp and world bank indicate that the level of co2 emission is going to rise six fold by 2025 with respect to the level of emissions in 1990 it is a great challenge to both meet the growth target and keep the co2 under control thereupon this paper tries to unfold factors that explain co2 emissions by undertaking a complete decomposition analysis for turkey over the period 1980 2003 the analysis shows as is common to relatively fast growing economies that the biggest contributor to the rise in co2 emissions is the expansion of the economy scale effect the carbon intensity and the change in composition of the economy which nearly move in tandem also contribute to the rise in co2 emissions albeit at a slower rate the energy intensity of the economy which is decreasing is responsible for a modest reduction in co2 emissions hence in congruence with the scale effect a decoupling of carbon emissions and economic growth is not found in turkey over the period 1980 2003

a nonparametric density estimation method for brand choice using scanner data nonparametric density estimation using a kernel method is proposed to model consumer brand choice recent availability of large scanner panel data allows the use of nonparametric approach which has few or at least fewer underlying assumptions and affords greater structural flexibility by removing as many assumptions as possible the author constructs the ultimate nonparametric model radically departing from the traditional approaches to highlight the differences in implementation and performance the proposed model does not involve either parameters that approximate certain distributions as in stochastic models or latent concepts such as utility as in utility maximization models the performance criteria include prediction of market response and brand choice share tracking and robustness under violation of various assumptions involved in parametric choice models such as correlated disturbance and misspecification the method is compared with a popular parametric counterpart the multinomial logit model on simulated and actual scanner panel data the paper emphasizes the conceptual importance of the nonparametric approach by discussing its advantages limitations and its complementary role in developing refining and diagnosing parametric models this perspective affords insight to modeling philosophy and suggests the possibility of a hybrid approach

cluster analysis of the relationship between carbon dioxide emissions and economic growth abstract as global warming continues to worsen the balance between carbon dioxide emissions and economic growth has received increasing attention and carbon reduction comes to be an urgent task in many countries in literature various regression models have been developed to investigate the relationship between carbon dioxide emissions and economic growth such as the inverted u shaped ekc model inverted n shaped model etc which play critical roles in analyzing the relationships existing studies suggest that some countries follow similar models to describe the relationships while others employ different ones regarding the interplay between carbon dioxide emissions and economic growth there lacks a cluster analysis to systematically uncover the similarity of countries that employ models more similar to each other than to the countries in other clusters in this paper a novel clustering approach is proposed to identify clusters of 67 countries from the spatial temporal and descriptive dimensions unlike the traditional clustering technique in which clusters are determined by geometric distances the clusters in this research are obtained based on the differences between the fitting models of the countries in each cluster the first step of the approach is to find clusters of countries sharing similar models in a given year based on the symbolic regression method and the second step is to determine the countries that frequently cooccur in the same cluster by the apriori algorithm the results present two high order clusters with different dynamic features during the period between 1971 and 2010 one high order cluster mainly consists of countries in higher level of income while the other contains lower income level countries and the carbon intensities of the two high order clusters have distinct differences the findings suggest that the countries within the same cluster could learn more lessons from each other while countries belonging to different clusters should not be examined together indiscriminately several policy implications are provided which may inform decision making for policymakers when choosing proper learning objects and help researchers with designing optimal models for specific countries

economic growth and energy consumption revisited evidence from linear and nonlinear granger causality the relationship between energy consumption and economic growth is considered as an imperative issue in energy economics previous studies have ignored the nonlinear behavior which could be caused by structural breaks in this study both linear and nonlinear granger causality tests are applied to examine the causal relationship between energy consumption and economic growth for a sample of asian newly industrialized countries as well as the u s this study finds evidence supporting a neutrality hypothesis for the united states thailand and south korea however empirical evidence on philippines and singapore reveals a unidirectional causality running from economic growth to energy consumption while energy consumption may have affected economic growth for taiwan hong kong malaysia and indonesia policy implications are also discussed

an international literature survey on energy economic growth nexus evidence from country specific studies in this paper an extensive review of the rapidly growing in the literature on the nexus between economic growth and four types of energy consumption total energy consumption electricity consumption nuclear consumption and renewable consumption the various hypotheses associated with the causal interaction between these variables along with a survey of the empirical literature are also discussed the survey focuses on country coverage periods modeling techniques and empirical conclusions a general observation from these studies that results are found to be sensitive to methodology and type of energy considered the empirical results for the specific countries surveyed show that i for energy consumption growth nexus 29 supported the growth hypothesis 27 the feedback hypothesis 23 the conservation hypothesis and 21 the neutrality hypothesis ii for the electricity consumption growth nexus 40 supported the growth hypothesis 33 the feedback hypothesis and 27 conservation hypothesis iii for the nuclear consumption growth nexus 60 supported the neutrality hypothesis and 40 the growth hypothesis and iv for the renewable consumption growth nexus 40 supported the neutrality hypothesis 40 the conservation hypothesis and 20 the growth hypothesis these mixed results may be attributed to the different used data selected variables and econometric approaches undertaken

system dynamics modelling and the environmental kuznets curve in ecuador 1980 2025 abstract is it possible for a country in the process of development to comply with the environmental kuznets curve ekc hypothesis in the medium term this is the question that inspired this study this paper is an extension of a previous study focused on economic development and co2 emissions in the coming years in ecuador robalino lopez et al submitted for publication the main goal of this paper is to analyze whether the ekc hypothesis holds within the period 1980 2025 under four different scenarios this paper uses co integration techniques stock and watson 2010 to test the existence of the ekc hypothesis in ecuador in the medium term using jaunky s 2011 specification our proposal goes a step further than previous contributions and intends to see under which conditions a country could approach the fulfilment of this hypothesis in the medium term results do not support the fulfilment of the ekc nevertheless our estimations show that ecuador could be on the way to achieving environmental stabilization in the near future if economic growth is combined with an increase in the use of renewable energies an improvement of the productive sectoral structure and the use of a more efficient fossil fuel technology

renewable energy policies and contradictions in causality a case of next 11 countries abstract numerous studies on the causal relationship between economic growth energy consumption and carbon dioxide co2 emissions have shown divergence in policy recommendations which arises mainly due to the choice of methodology and the period of study this inconclusiveness in policy prescriptions might turn out to be critical when the renewable energy policies of the developing nations are considered our study analyses the causal relationship between economic growth carbon emissions fossil fuel and renewable energy consumption in next 11 countries during the period of 1990 2016 along with conducting parametric and non parametric causality tests together introducing the geweke 1982 causality test in the literature of energy economics we attempt to establish a wholesome aspect of policy design by comparing and complementing results of different causality analysis and how the causality directions should comply with the context setting our empirical evidence confirms that robust renewable energy policy can be designed by complementing the various causality test results rather than focusing on one particular causality test

revisiting the environmental kuznets curve in a global economy the present study deals with an empirical investigation between co2 emissions energy intensity economic growth and globalization using annual data over the period of 1970 2010 for turkish economy we applied unit root test and cointegration approach in the presence of structural breaks the direction of causality between the variables is investigated by applying the vecm granger causality approach our results confirmed the existence of cointegration between the series the empirical evidence reported that energy intensity and economic growth globalization increase condense co2 emissions the results also validated the presence of environmental kuznets curve ekc the causality analysis shows bidirectional causality between economic growth and co2 emissions this implies that economic growth can be boosted at the cost of environment

co2 emissions energy consumption and output in france abstract this paper examines the dynamic causal relationships between pollutant emissions energy consumption and output for france using cointegration and vector error correction modelling techniques we argue that these variables are strongly inter related and therefore their relationship must be examined using an integrated framework the results provide evidence for the existence of a fairly robust long run relationship between these variables for the period 1960 2000 the causality results support the argument that economic growth exerts a causal influence on growth of energy use and growth of pollution in the long run the results also point to a uni directional causality running from growth of energy use to output growth in the short run

energy consumption income and carbon emissions in the united states abstract this paper investigates the effect of energy consumption and output on carbon emissions in the united states earlier research focused on testing the existence and or shape of an environmental kuznets curve without taking energy consumption into account we investigate the granger causality relationship between income energy consumption and carbon emissions including labor and gross fixed capital formation in the model we find that income does not granger cause carbon emissions in the us in the long run but energy use does hence income growth by itself may not become a solution to environmental problems

urbanization economic growth energy consumption and co2 emissions empirical evidence from countries with different income levels abstract the growth of anthropogenic co2 emissions has been widely attributed to the combustion of energy in support of human activities associated with economic development while the link between urbanization economic growth energy consumption and co2 emissions has as a result received considerable multidisciplinary scholarly attention little work has been undertaken with respect to the how differences in the development stages or income levels of the countries studied may affect these relations here we empirically explore the link between urbanization economic development energy consumption and co2 emissions specifically taking into account the different income levels of the countries studied a series of panel data models and a balanced dataset for a panel of 170 countries were utilized in the study which took the period of 1980 2011 into consideration the result of panel cointegration tests suggested that a cointegration relationship existed between variables in all the countries studied and that a statistically significant positive relationship existed between the variables employed in the long run the results of a granger causality test based on the vector error correction model vecm provided evidence of varied granger causality relationships between the variables across the income based subpanels moreover we also undertook an impulse response and variance decomposition analysis that allowed us to forecast the impacts of economic growth urbanization and energy consumption on future co2 emissions during the period surveyed our results cast a new light on the importance of a country s development stage and income level for government policy decisions relating to the reduction of co2 emissions

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment
